It aims to go beyond what can be done in current accounting software. \nThe list of non-exhaustive services under consideration are as follows: \n- A working PoC model developed and demonstrated in supplier(s) test / sandbox environment which tests how synthetic transactions can be: \n-- produced or captured (automatically, manually or via a hybrid approach) \n-- transferred to accounting software \n-- coordinated and used by accounting software to calculate tax liabilities across multiple income and expense streams \n-- transferred to HMRC via existing infrastructure (e.g. Making Tax Digital APIs) \n- Uses realistic supplier-generated synthetic data for two HMRC defined personas.  \n- Demonstrates model impact on HMRC defined transactions which are commonly mis-categorised; mis-apportioned; have unclear gross / net settlements. \n- Sufficient build and operational detail to demonstrate end-to-end feasibility, rather than solely conceptual designs or options appraisals. \nThese products/services are expected to be key enablers to delivering the following capabilities:  \n- Tax system simplification \n- Upstream compliance \n- Customer financial clarity and cash-flow management \n- Business systems integration \n- End-to-end data propagation  \n- API handling \nHRMC are considering phasing this procurement into the following: (1) preparation; (2) build; (3) test and evaluation with conditional progression to build phase subject to agreed success criteria. \nPhase 1: Preparation (8 weeks): \n- Supplier generation of robust realistic synthetic payment data (assured by HMRC) \n- Supplier evaluation plan including impact metrics  \n- Baseline of synthetic payment data established \n- System design blueprint of proposed working model  \nPhase 2: Build (12 weeks): \n- Design sprints including extensive records, resulting in the working technical demonstrator.  \n- Model must be developed and demonstrated in supplier(s) test / sandbox environment using agreed synthetic data \nPhase 3: Test and evaluation (6 weeks testing, 6 weeks evaluation): \n- Test of the technical demonstrator by the supplier(s) and HMRC, against agreed metrics \n- Evaluation reports of the technical demonstrator, including scalability and re-use recommendations \nThis PoC approach is focused on structured discovery and learning. It is not a commitment to implement a specific solution, technical design, or live service.",

                        "description": "This is NOT a call for competition or requests to participate.\nThis IS notice of a planned procurement.\nHis Majesty's Revenue and Customs (HMRC) intends to commence a competitive procurement for the delivery of an innovation-led Proof of Concept (PoC) exploring how emerging technologies, richer transaction data and integrations across banking, payment, fintech and software ecosystems could support increased simplification and accuracy within Income Tax Self Assessment (ITSA).\nThe PoC will build, test and evaluate a working technical demonstrator. Its purpose is to generate evidence and learning, rather than develop a live service or commit HMRC to a specific future solution.\nThis work supports HMRC's Transformation Roadmap and aligns with HMRC's Strategic Approach to Third Party Software. It explores how banking, payments, fintech and software ecosystems can help customers manage their tax affairs through the products and services they already use, reducing administrative effort, improving visibility of tax obligations and helping customers get their tax right first time, while building on a thriving and innovative market.\nMaking Tax Digital (MTD) for Income Tax provides the digital foundations for ITSA and continues to roll out. Innovation across banking, payments, fintech and software markets presents opportunities to develop, test and better understand ecosystem approaches to support more efficient and effective tax administration that makes it simpler for customers to meet their tax responsibilities.\nFor many ITSA customers, software and fintech products already provide valuable automation and support, helping many customers to manage their tax affairs more efficiently. However, richer data, improved standards and greater interoperability may create opportunities to further enhance transaction categorisation and apportionment, reducing customer effort, supporting customer experience and ensuring more accurate tax outcomes.\nHMRC wants to test and learn with the market how banks, payment providers, fintechs and software platforms can build on existing capabilities to deliver more integrated, accurate and customer-centred tax experiences, while supporting a thriving and innovative software ecosystem.\nThe central question for the PoC is: to what extent can future enhanced data, ecosystem integrations, and interventions reduce customer effort, improve customer experience and improve accuracy across more aspects of Income Tax Self Assessment?\nHMRC welcomes ideas from suppliers which innovate further, building on today, and looking towards future capabilities. Suppliers are welcome to bid independently or in partnership to build, test and evaluate an end-to-end working technical demonstrator of enhanced future capabilities and integrations. Alongside SMEs, HMRC anticipates that this procurement will be suitable for participation by consortia involving banks, payment providers, fintechs and accounting software providers.\nThe following services are indicative and non-exhaustive:\n•\tprovision of a sandbox or test environment;\n•\tcreation and management of HMRC defined, persona-based synthetic transaction datasets, with sufficient complexity, realism and scale to fully test the technical demonstrator;\n•\tdesign, build and operation of a realistic working technical demonstrator showing how future ecosystem data and integrations could impact on transactions, including categorisation, apportionment, or establishment of gross and net income positions;\n•\ttesting against agreed evaluation measures, including transaction treatment accuracy, tax calculation accuracy, and customer effort; and\n•\tevaluation of findings, lessons learned, and recommendations for potential future application.\nThrough the procurement HMRC may seek information relating to:\n•\tecosystem data sources and standards available to suppliers;\n•\taccessibility, availability and interoperability of those data sources across accounting software providers and other ecosystem participants;\n•\tapplicability of data sources and integrations across the ITSA population;\n•\tcommercial, operational or legal factors affecting ecosystem sharing and interoperability;\n•\tthe strengths and limitations of current and emerging approaches.\nThrough the PoC HMRC aims to:\n•\tgenerate evidence on the value of enriched ecosystem data, integrations and emerging technologies; and\n•\tevaluate how emerging banking, payments, fintech and software capabilities can work together to support an accurate and efficient ITSA.",

However, richer data, improved standards and greater interoperability may create opportunities to further enhance transaction categorisation and apportionment, reducing customer effort, supporting customer experience and ensuring more accurate tax outcomes.\nHMRC wants to test and learn with the market how banks, payment providers, fintechs and software platforms can build on existing capabilities to deliver more integrated, accurate and customer-centred tax experiences, while supporting a thriving and innovative software ecosystem.\nThe central question for the PoC is: to what extent can future enhanced data, ecosystem integrations, and interventions reduce customer effort, improve customer experience and improve accuracy across more aspects of Income Tax Self Assessment?\nHMRC welcomes ideas from suppliers which innovate further, building on today, and looking towards future capabilities. Suppliers are welcome to bid independently or in partnership to build, test and evaluate an end-to-end working technical demonstrator of enhanced future capabilities and integrations. Alongside SMEs, HMRC anticipates that this procurement will be suitable for participation by consortia involving banks, payment providers, fintechs and accounting software providers.\nThe following services are indicative and non-exhaustive:\n•\tprovision of a sandbox or test environment;\n•\tcreation and management of HMRC defined, persona-based synthetic transaction datasets, with sufficient complexity, realism and scale to fully test the technical demonstrator;\n•\tdesign, build and operation of a realistic working technical demonstrator showing how future ecosystem data and integrations could impact on transactions, including categorisation, apportionment, or establishment of gross and net income positions;\n•\ttesting against agreed evaluation measures, including transaction treatment accuracy, tax calculation accuracy, and customer effort; and\n•\tevaluation of findings, lessons learned, and recommendations for potential future application.\nThrough the procurement HMRC may seek information relating to:\n•\tecosystem data sources and standards available to suppliers;\n•\taccessibility, availability and interoperability of those data sources across accounting software providers and other ecosystem participants;\n•\tapplicability of data sources and integrations across the ITSA population;\n•\tcommercial, operational or legal factors affecting ecosystem sharing and interoperability;\n•\tthe strengths and limitations of current and emerging approaches.\nThrough the PoC HMRC aims to:\n•\tgenerate evidence on the value of enriched ecosystem data, integrations and emerging technologies; and\n•\tevaluate how emerging banking, payments, fintech and software capabilities can work together to support an accurate and efficient ITSA.",

It aims to go beyond what can be done in current accounting software.\nThe list of non-exhaustive services under consideration are as follows:\n- A working PoC model developed and demonstrated in supplier(s) test / sandbox environment which tests how synthetic transactions can be:\n-- produced or captured (automatically, manually or via a hybrid approach)\n-- transferred to accounting software\n-- coordinated and used by accounting software to calculate tax liabilities across multiple income and expense streams\n-- transferred to HMRC via existing infrastructure (e.g. Making Tax Digital APIs)\n- Uses realistic supplier-generated synthetic data for two HMRC defined personas.\n- Demonstrates model impact on HMRC defined transactions which are commonly mis-categorised; mis-apportioned; have unclear gross / net settlements.\n- Sufficient build and operational detail to demonstrate end-to-end feasibility, rather than solely conceptual designs or options appraisals.\nThese products/services are expected to be key enablers to delivering the following capabilities:\n- Tax system simplification\n- Upstream compliance\n- Customer financial clarity and cash-flow management\n- Business systems integration\n- End-to-end data propagation\n- API handling\nHRMC are considering phasing this procurement into the following: (1) preparation; (2) build; (3) test and evaluation with conditional progression to build phase subject to agreed success criteria.\nPhase 1: Preparation (8 weeks):\n- Supplier generation of robust realistic synthetic payment data (assured by HMRC)\n- Supplier evaluation plan including impact metrics\n- Baseline of synthetic payment data established\n- System design blueprint of proposed working model\nPhase 2: Build (12 weeks):\n- Design sprints including extensive records, resulting in the working technical demonstrator. \n- Model must be developed and demonstrated in supplier(s) test / sandbox environment using agreed synthetic data\nPhase 3: Test and evaluation (6 weeks testing, 6 weeks evaluation):\n- Test of the technical demonstrator by the supplier(s) and HMRC, against agreed metrics\n- Evaluation reports of the technical demonstrator, including scalability and re-use recommendations \nThis PoC approach is focused on structured discovery and learning. It is not a commitment to implement a specific solution, technical design, or live service.",

Its purpose is to generate evidence and learning, rather than develop a live service or commit HMRC to a specific future solution.\nThis work supports HMRC's Transformation Roadmap and aligns with HMRC's Strategic Approach to Third Party Software. It explores how banking, payments, fintech and software ecosystems can help customers manage their tax affairs through the products and services they already use, reducing administrative effort, improving visibility of tax obligations and helping customers get their tax right first time, while building on a thriving and innovative market.\nMaking Tax Digital (MTD) for Income Tax provides the digital foundations for ITSA and continues to roll out. Innovation across banking, payments, fintech and software markets presents opportunities to develop, test and better understand ecosystem approaches to support more efficient and effective tax administration that makes it simpler for customers to meet their tax responsibilities.\nFor many ITSA customers, software and fintech products already provide valuable automation and support, helping many customers to manage their tax affairs more efficiently. However, richer data, improved standards and greater interoperability may create opportunities to further enhance transaction categorisation and apportionment, reducing customer effort, supporting customer experience and ensuring more accurate tax outcomes.\nHMRC wants to test and learn with the market how banks, payment providers, fintechs and software platforms can build on existing capabilities to deliver more integrated, accurate and customer-centred tax experiences, while supporting a thriving and innovative software ecosystem.\nThe central question for the PoC is: to what extent can future enhanced data, ecosystem integrations, and interventions reduce customer effort, improve customer experience and improve accuracy across more aspects of Income Tax Self Assessment?\nHMRC welcomes ideas from suppliers which innovate further, building on today, and looking towards future capabilities. Suppliers are welcome to bid independently or in partnership to build, test and evaluate an end-to-end working technical demonstrator of enhanced future capabilities and integrations. Alongside SMEs, HMRC anticipates that this procurement will be suitable for participation by consortia involving banks, payment providers, fintechs and accounting software providers.",

HMRC reserves the right to amend this process at the beginning of each stage by updating this tender instruction document or by issue of letters to bidders participating in the relevant stage. Any updates will be issued simultaneously to all suppliers via SAP Ariba.\nThe 2 stages will be as follows:\nStage 1: Invitation to submit initial tender - Video submissions and Pre-Selection Questionnaire (PSQ)\nStage 2: Final tender - Solution presentation, demonstration, and written tender\nSTAGE 1:\n(a)\tStage 1 commenced with the issuing of a Tender Notice and the publication of this document.\n(b)\tThis document includes a procurement specific questionnaire (PSQ) and quality questions at Schedules 1 and 2 which all suppliers are required to complete and return in accordance with the Procurement Timetable and instructions within this document.\n(c)\tHMRC will use this stage to firstly confirm that neither the supplier, nor any related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are listed on the Cabinet Office debarment list. To the extent that any such entities are listed on the debarment list, HMRC will consider whether to exclude the supplier from participating in the Procurement in accordance with its obligations under the Act. \n(d)\tIn addition, HMRC will consider whether any supplier or related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are excluded or excludable suppliers, and before HMRC determines that a supplier is an excluded or excludable supplier, it will provide the supplier reasonable opportunity to make representations and provide evidence as is proportionate in the circumstances. If the supplier is an excluded or excludable supplier only by virtue of an associated person or proposed sub-contractor, HMRC will notify the supplier of its intention to exclude the supplier and provide the supplier with reasonable opportunity to replace the associated person or sub-contractor. If as a consequence of this process HMRC excludes the supplier from participating in the Procurement, or is aware of an associated person or sub-contract having been replaced, it will give notice of this fact within 30 days of its decision to the Procurement Review Unit (PRU).\n(e)\tHMRC will also undertake a review of the completed PSQ with reference to any information held on the Central Digital Platform. Responses to any conditions of participation will be assessed in accordance with the selection process and any selection criteria as set out in the Tender Notice, PSQ and described in this document.\n(f)\tThe assessment of suppliers utilising PSQ, as detailed above, will be undertaken prior to the evaluation of bid submissions for stage 1. Suppliers are required to submit their PSQ through Ariba. \n(g)\tAs part of their stage 1 submission, alongside the PSQ, suppliers must submit a video up to a maximum of 5 minutes duration providing their response to the questions set out in Schedule 2: Quality Evaluation Criteria.\n(h)\tSuppliers should submit a video using the instructions provided in Section 7.5 'Stage 1 video submission' below. Additionally, suppliers must submit a transcript of their video, with a maximum of 750 words. \n(i)\tThe video and associated 750-word transcript must cover the questions set out in Schedule 2: Quality Evaluation Criteria. The supplier should note that the transcript must answer the questions set out in Schedule 2: Quality Evaluation Criteria, and that the video should be used for supplementary presentation and delivery purposes only - i.e. information that is not well suited to communicating via written (the transcript) or spoken word. For example, acceptable video content would include (but is not limited to) demonstrations, animations, graphs and charts, supporting visual/practical aids etc.). HRMC reserves the right to exclude bidders who utilise the video submission to provide excessive additional content which could have been adequately conveyed in the speech of the video and accompanying transcript. For example, unacceptable video content would include (but is not limited to) a PowerPoint presentation that features significant text that the bidder intends the evaluators to assess over and above the 750-word transcript.\n(j)\tStage 1 will complete with suppliers being notified in writing of whether or not they have been successfully shortlisted to participate in stage 2.\n(k)\tHMRC intends to shortlist a maximum of 3 suppliers to participate in stage 2.\n(l)\tHMRC may, at its discretion, invite a bidder to form a partnership or consortium with another competitor.\n(m)\tSuppliers should note that HMRC reserves the right to re-assess any response to the PSQ, in light of any new relevant information that comes to HMRC's attention. \nSuppliers selected to participate in Stage 2 will received a fixed amount of funding of £8,000 exVAT to support their continued participation in the process.\nFull details are included in the competition documents available upon registration.\nConditions of participation may be included in any stage. Where included this will be communicated in the letter or instructions for that stage."

                        "description": "HM Revenue and Customs (HMRC) has launched a competitive procurement for the delivery of an innovation-led Proof of Concept (PoC) exploring how emerging technologies, richer transaction data and integrations across banking, payment, fintech and software ecosystems could support increased simplification and accuracy within Income Tax Self Assessment (ITSA).\nThe PoC will build, test and evaluate a working technical demonstrator. Its purpose is to generate evidence and learning, rather than develop a live service or commit HMRC to a specific future solution.\nThis work supports HMRC's Transformation Roadmap and aligns with HMRC's Strategic Approach to Third Party Software. It explores how banking, payments, fintech and software ecosystems can help customers manage their tax affairs through the products and services they already use, reducing administrative effort, improving visibility of tax obligations and helping customers get their tax right first time, while building on a thriving and innovative market.\nMaking Tax Digital (MTD) for Income Tax provides the digital foundations for ITSA and continues to roll out. Innovation across banking, payments, fintech and software markets presents opportunities to develop, test and better understand ecosystem approaches to support more efficient and effective tax administration that makes it simpler for customers to meet their tax responsibilities.\nFor many ITSA customers, software and fintech products already provide valuable automation and support, helping many customers to manage their tax affairs more efficiently. However, richer data, improved standards and greater interoperability may create opportunities to further enhance transaction categorisation and apportionment, reducing customer effort, supporting customer experience and ensuring more accurate tax outcomes.\nHMRC wants to test and learn with the market how banks, payment providers, fintechs and software platforms can build on existing capabilities to deliver more integrated, accurate and customer-centred tax experiences, while supporting a thriving and innovative software ecosystem.\nThe central question for the PoC is: to what extent can future enhanced data, ecosystem integrations, and interventions reduce customer effort, improve customer experience and improve accuracy across more aspects of Income Tax Self Assessment?\nHMRC welcomes ideas from suppliers which innovate further, building on today, and looking towards future capabilities. Suppliers are welcome to bid independently or in partnership to build, test and evaluate an end-to-end working technical demonstrator of enhanced future capabilities and integrations. Alongside SMEs, HMRC anticipates that this procurement will be suitable for participation by consortia involving banks, payment providers, fintechs and accounting software providers.",

HMRC reserves the right to amend this process at the beginning of each stage by updating this tender instruction document or by issue of letters to bidders participating in the relevant stage. Any updates will be issued simultaneously to all suppliers via SAP Ariba.\nThe 2 stages will be as follows:\nStage 1: Invitation to submit initial tender - Video submissions and Pre-Selection Questionnaire (PSQ)\nStage 2: Final tender - Solution presentation, demonstration, and written tender\nSTAGE 1:\n(a)\tStage 1 commenced with the issuing of a Tender Notice and the publication of this document.\n(b)\tThis document includes a procurement specific questionnaire (PSQ) and quality questions at Schedules 1 and 2 which all suppliers are required to complete and return in accordance with the Procurement Timetable and instructions within this document.\n(c)\tHMRC will use this stage to firstly confirm that neither the supplier, nor any related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are listed on the Cabinet Office debarment list. To the extent that any such entities are listed on the debarment list, HMRC will consider whether to exclude the supplier from participating in the Procurement in accordance with its obligations under the Act.\n(d)\tIn addition, HMRC will consider whether any supplier or related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are excluded or excludable suppliers, and before HMRC determines that a supplier is an excluded or excludable supplier, it will provide the supplier reasonable opportunity to make representations and provide evidence as is proportionate in the circumstances. If the supplier is an excluded or excludable supplier only by virtue of an associated person or proposed sub-contractor, HMRC will notify the supplier of its intention to exclude the supplier and provide the supplier with reasonable opportunity to replace the associated person or sub-contractor. If as a consequence of this process HMRC excludes the supplier from participating in the Procurement, or is aware of an associated person or sub-contract having been replaced, it will give notice of this fact within 30 days of its decision to the Procurement Review Unit (PRU).\n(e)\tHMRC will also undertake a review of the completed PSQ with reference to any information held on the Central Digital Platform. Responses to any conditions of participation will be assessed in accordance with the selection process and any selection criteria as set out in the Tender Notice, PSQ and described in this document.\n(f)\tThe assessment of suppliers utilising PSQ, as detailed above, will be undertaken prior to the evaluation of bid submissions for stage 1. Suppliers are required to submit their PSQ through Ariba.\n(g)\tAs part of their stage 1 submission, alongside the PSQ, suppliers must submit a video up to a maximum of 5 minutes duration providing their response to the questions set out in Schedule 2: Quality Evaluation Criteria.\n(h)\tSuppliers should submit a video using the instructions provided in Section 7.5 'Stage 1 video submission' below. Additionally, suppliers must submit a transcript of their video, with a maximum of 750 words.\n(i)\tThe video and associated 750-word transcript must cover the questions set out in Schedule 2: Quality Evaluation Criteria. The supplier should note that the transcript must answer the questions set out in Schedule 2: Quality Evaluation Criteria, and that the video should be used for supplementary presentation and delivery purposes only - i.e. information that is not well suited to communicating via written (the transcript) or spoken word. For example, acceptable video content would include (but is not limited to) demonstrations, animations, graphs and charts, supporting visual/practical aids etc.). HRMC reserves the right to exclude bidders who utilise the video submission to provide excessive additional content which could have been adequately conveyed in the speech of the video and accompanying transcript. For example, unacceptable video content would include (but is not limited to) a PowerPoint presentation that features significant text that the bidder intends the evaluators to assess over and above the 750-word transcript.\n(j)\tStage 1 will complete with suppliers being notified in writing of whether or not they have been successfully shortlisted to participate in stage 2.\n(k)\tHMRC intends to shortlist a maximum of 3 suppliers to participate in stage 2.\n(l)\tHMRC may, at its discretion, invite a bidder to form a partnership or consortium with another competitor.\n(m)\tSuppliers should note that HMRC reserves the right to re-assess any response to the PSQ, in light of any new relevant information that comes to HMRC's attention.\nSuppliers selected to participate in Stage 2 will received a fixed amount of funding of £8,000 exVAT to support their continued participation in the process.\nFull details are included in the competition documents available upon registration.\nConditions of participation may be included in any stage. Where included this will be communicated in the letter or instructions for that stage."

                        "description": "HM Revenue and Customs (HMRC) has launched a competitive procurement for the delivery of an innovation-led Proof of Concept (PoC) exploring how emerging technologies, richer transaction data and integrations across banking, payment, fintech and software ecosystems could support increased simplification and accuracy within Income Tax Self Assessment (ITSA).\nThe PoC will build, test and evaluate a working technical demonstrator. Its purpose is to generate evidence and learning, rather than develop a live service or commit HMRC to a specific future solution.\nThis work supports HMRC's Transformation Roadmap and aligns with HMRC's Strategic Approach to Third Party Software. It explores how banking, payments, fintech and software ecosystems can help customers manage their tax affairs through the products and services they already use, reducing administrative effort, improving visibility of tax obligations and helping customers get their tax right first time, while building on a thriving and innovative market.\nMaking Tax Digital (MTD) for Income Tax provides the digital foundations for ITSA and continues to roll out. Innovation across banking, payments, fintech and software markets presents opportunities to develop, test and better understand ecosystem approaches to support more efficient and effective tax administration that makes it simpler for customers to meet their tax responsibilities.\nFor many ITSA customers, software and fintech products already provide valuable automation and support, helping many customers to manage their tax affairs more efficiently. However, richer data, improved standards and greater interoperability may create opportunities to further enhance transaction categorisation and apportionment, reducing customer effort, supporting customer experience and ensuring more accurate tax outcomes.\nHMRC wants to test and learn with the market how banks, payment providers, fintechs and software platforms can build on existing capabilities to deliver more integrated, accurate and customer-centred tax experiences, while supporting a thriving and innovative software ecosystem.\nThe central question for the PoC is: to what extent can future enhanced data, ecosystem integrations, and interventions reduce customer effort, improve customer experience and improve accuracy across more aspects of Income Tax Self Assessment?\nHMRC welcomes ideas from suppliers which innovate further, building on today, and looking towards future capabilities. Suppliers are welcome to bid independently or in partnership to build, test and evaluate an end-to-end working technical demonstrator of enhanced future capabilities and integrations. Alongside SMEs, HMRC anticipates that this procurement will be suitable for participation by consortia involving banks, payment providers, fintechs and accounting software providers.",

HMRC reserves the right to amend this process at the beginning of each stage by updating this tender instruction document or by issue of letters to bidders participating in the relevant stage. Any updates will be issued simultaneously to all suppliers via SAP Ariba.\nThe 2 stages will be as follows:\nStage 1: Invitation to submit initial tender - Video submissions and Pre-Selection Questionnaire (PSQ)\nStage 2: Final tender - Solution presentation, demonstration, and written tender\nSTAGE 1:\n(a)\tStage 1 commenced with the issuing of a Tender Notice and the publication of this document.\n(b)\tThis document includes a procurement specific questionnaire (PSQ) and quality questions at Schedules 1 and 2 which all suppliers are required to complete and return in accordance with the Procurement Timetable and instructions within this document.\n(c)\tHMRC will use this stage to firstly confirm that neither the supplier, nor any related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are listed on the Cabinet Office debarment list. To the extent that any such entities are listed on the debarment list, HMRC will consider whether to exclude the supplier from participating in the Procurement in accordance with its obligations under the Act.\n(d)\tIn addition, HMRC will consider whether any supplier or related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are excluded or excludable suppliers, and before HMRC determines that a supplier is an excluded or excludable supplier, it will provide the supplier reasonable opportunity to make representations and provide evidence as is proportionate in the circumstances. If the supplier is an excluded or excludable supplier only by virtue of an associated person or proposed sub-contractor, HMRC will notify the supplier of its intention to exclude the supplier and provide the supplier with reasonable opportunity to replace the associated person or sub-contractor. If as a consequence of this process HMRC excludes the supplier from participating in the Procurement, or is aware of an associated person or sub-contract having been replaced, it will give notice of this fact within 30 days of its decision to the Procurement Review Unit (PRU).\n(e)\tHMRC will also undertake a review of the completed PSQ with reference to any information held on the Central Digital Platform. Responses to any conditions of participation will be assessed in accordance with the selection process and any selection criteria as set out in the Tender Notice, PSQ and described in this document.\n(f)\tThe assessment of suppliers utilising PSQ, as detailed above, will be undertaken prior to the evaluation of bid submissions for stage 1. Suppliers are required to submit their PSQ through Ariba.\n(g)\tAs part of their stage 1 submission, alongside the PSQ, suppliers must submit a video up to a maximum of 5 minutes duration providing their response to the questions set out in Schedule 2: Quality Evaluation Criteria.\n(h)\tSuppliers should submit a video using the instructions provided in Section 7.5 'Stage 1 video submission' below. Additionally, suppliers must submit a transcript of their video, with a maximum of 750 words.\n(i)\tThe video and associated 750-word transcript must cover the questions set out in Schedule 2: Quality Evaluation Criteria. The supplier should note that the transcript must answer the questions set out in Schedule 2: Quality Evaluation Criteria, and that the video should be used for supplementary presentation and delivery purposes only - i.e. information that is not well suited to communicating via written (the transcript) or spoken word. For example, acceptable video content would include (but is not limited to) demonstrations, animations, graphs and charts, supporting visual/practical aids etc.). HRMC reserves the right to exclude bidders who utilise the video submission to provide excessive additional content which could have been adequately conveyed in the speech of the video and accompanying transcript. For example, unacceptable video content would include (but is not limited to) a PowerPoint presentation that features significant text that the bidder intends the evaluators to assess over and above the 750-word transcript.\n(j)\tStage 1 will complete with suppliers being notified in writing of whether or not they have been successfully shortlisted to participate in stage 2.\n(k)\tHMRC intends to shortlist a maximum of 3 suppliers to participate in stage 2.\n(l)\tHMRC may, at its discretion, invite a bidder to form a partnership or consortium with another competitor.\n(m)\tSuppliers should note that HMRC reserves the right to re-assess any response to the PSQ, in light of any new relevant information that comes to HMRC's attention.\nSuppliers selected to participate in Stage 2 will received a fixed amount of funding of £8,000 exVAT to support their continued participation in the process.\nFull details are included in the competition documents available upon registration.\nConditions of participation may be included in any stage. Where included this will be communicated in the letter or instructions for that stage."

                    "description": "HM Revenue and Customs (HMRC) has launched a competitive procurement for the delivery of an innovation-led Proof of Concept (PoC) exploring how emerging technologies, richer transaction data and integrations across banking, payment, fintech and software ecosystems could support increased simplification and accuracy within Income Tax Self Assessment (ITSA).\nThe PoC will build, test and evaluate a working technical demonstrator. Its purpose is to generate evidence and learning, rather than develop a live service or commit HMRC to a specific future solution.\nThis work supports HMRC's Transformation Roadmap and aligns with HMRC's Strategic Approach to Third Party Software. It explores how banking, payments, fintech and software ecosystems can help customers manage their tax affairs through the products and services they already use, reducing administrative effort, improving visibility of tax obligations and helping customers get their tax right first time, while building on a thriving and innovative market.\nMaking Tax Digital (MTD) for Income Tax provides the digital foundations for ITSA and continues to roll out. Innovation across banking, payments, fintech and software markets presents opportunities to develop, test and better understand ecosystem approaches to support more efficient and effective tax administration that makes it simpler for customers to meet their tax responsibilities.\nFor many ITSA customers, software and fintech products already provide valuable automation and support, helping many customers to manage their tax affairs more efficiently. However, richer data, improved standards and greater interoperability may create opportunities to further enhance transaction categorisation and apportionment, reducing customer effort, supporting customer experience and ensuring more accurate tax outcomes.\nHMRC wants to test and learn with the market how banks, payment providers, fintechs and software platforms can build on existing capabilities to deliver more integrated, accurate and customer-centred tax experiences, while supporting a thriving and innovative software ecosystem.\nThe central question for the PoC is: to what extent can future enhanced data, ecosystem integrations, and interventions reduce customer effort, improve customer experience and improve accuracy across more aspects of Income Tax Self Assessment?\nHMRC welcomes ideas from suppliers which innovate further, building on today, and looking towards future capabilities. Suppliers are welcome to bid independently or in partnership to build, test and evaluate an end-to-end working technical demonstrator of enhanced future capabilities and integrations. Alongside SMEs, HMRC anticipates that this procurement will be suitable for participation by consortia involving banks, payment providers, fintechs and accounting software providers.",

HMRC reserves the right to amend this process at the beginning of each stage by updating this tender instruction document or by issue of letters to bidders participating in the relevant stage. Any updates will be issued simultaneously to all suppliers via SAP Ariba.\nThe 2 stages will be as follows:\nStage 1: Invitation to submit initial tender - Video submissions and Pre-Selection Questionnaire (PSQ)\nStage 2: Final tender - Solution presentation, demonstration, and written tender\nSTAGE 1:\n(a)\tStage 1 commenced with the issuing of a Tender Notice and the publication of this document.\n(b)\tThis document includes a procurement specific questionnaire (PSQ) and quality questions at Schedules 1 and 2 which all suppliers are required to complete and return in accordance with the Procurement Timetable and instructions within this document.\n(c)\tHMRC will use this stage to firstly confirm that neither the supplier, nor any related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are listed on the Cabinet Office debarment list. To the extent that any such entities are listed on the debarment list, HMRC will consider whether to exclude the supplier from participating in the Procurement in accordance with its obligations under the Act.\n(d)\tIn addition, HMRC will consider whether any supplier or related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are excluded or excludable suppliers, and before HMRC determines that a supplier is an excluded or excludable supplier, it will provide the supplier reasonable opportunity to make representations and provide evidence as is proportionate in the circumstances. If the supplier is an excluded or excludable supplier only by virtue of an associated person or proposed sub-contractor, HMRC will notify the supplier of its intention to exclude the supplier and provide the supplier with reasonable opportunity to replace the associated person or sub-contractor. If as a consequence of this process HMRC excludes the supplier from participating in the Procurement, or is aware of an associated person or sub-contract having been replaced, it will give notice of this fact within 30 days of its decision to the Procurement Review Unit (PRU).\n(e)\tHMRC will also undertake a review of the completed PSQ with reference to any information held on the Central Digital Platform. Responses to any conditions of participation will be assessed in accordance with the selection process and any selection criteria as set out in the Tender Notice, PSQ and described in this document.\n(f)\tThe assessment of suppliers utilising PSQ, as detailed above, will be undertaken prior to the evaluation of bid submissions for stage 1. Suppliers are required to submit their PSQ through Ariba.\n(g)\tAs part of their stage 1 submission, alongside the PSQ, suppliers must submit a video up to a maximum of 5 minutes duration providing their response to the questions set out in Schedule 2: Quality Evaluation Criteria.\n(h)\tSuppliers should submit a video using the instructions provided in Section 7.5 'Stage 1 video submission' below. Additionally, suppliers must submit a transcript of their video, with a maximum of 750 words.\n(i)\tThe video and associated 750-word transcript must cover the questions set out in Schedule 2: Quality Evaluation Criteria. The supplier should note that the transcript must answer the questions set out in Schedule 2: Quality Evaluation Criteria, and that the video should be used for supplementary presentation and delivery purposes only - i.e. information that is not well suited to communicating via written (the transcript) or spoken word. For example, acceptable video content would include (but is not limited to) demonstrations, animations, graphs and charts, supporting visual/practical aids etc.). HRMC reserves the right to exclude bidders who utilise the video submission to provide excessive additional content which could have been adequately conveyed in the speech of the video and accompanying transcript. For example, unacceptable video content would include (but is not limited to) a PowerPoint presentation that features significant text that the bidder intends the evaluators to assess over and above the 750-word transcript.\n(j)\tStage 1 will complete with suppliers being notified in writing of whether or not they have been successfully shortlisted to participate in stage 2.\n(k)\tHMRC intends to shortlist a maximum of 3 suppliers to participate in stage 2.\n(l)\tHMRC may, at its discretion, invite a bidder to form a partnership or consortium with another competitor.\n(m)\tSuppliers should note that HMRC reserves the right to re-assess any response to the PSQ, in light of any new relevant information that comes to HMRC's attention.\nSuppliers selected to participate in Stage 2 will received a fixed amount of funding of £8,000 exVAT to support their continued participation in the process.\nFull details are included in the competition documents available upon registration.\nConditions of participation may be included in any stage. Where included this will be communicated in the letter or instructions for that stage."

To the extent that any such entities are listed on the debarment list, HMRC will consider whether to exclude the supplier from participating in the Procurement in accordance with its obligations under the Act. \n(d)\tIn addition, HMRC will consider whether any supplier or related persons within its corporate group, associated persons relied on to meet the conditions of participation, or proposed sub-contractors are excluded or excludable suppliers, and before HMRC determines that a supplier is an excluded or excludable supplier, it will provide the supplier reasonable opportunity to make representations and provide evidence as is proportionate in the circumstances. If the supplier is an excluded or excludable supplier only by virtue of an associated person or proposed sub-contractor, HMRC will notify the supplier of its intention to exclude the supplier and provide the supplier with reasonable opportunity to replace the associated person or sub-contractor.
