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 20 'How to respond to this opportunity' 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 both of the two questions above. The supplier should note that the transcript must answer both questions detailed above, 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.

This is driven by a range of customer behaviours from simple error through to deliberate evasion. Identifying deliberate evasion is inherently difficult across a very large population of more than 5m customers. By its nature its intent is to hide and deceive. This can lead to risk targeting and response being more costly for HMRC which impacts on our ability to close the tax gap and can increase burdens on compliant customers.\nUsing data to identify potential deliberate evasion in our analytical risking processes may help improve HMRC's approach to managing this risk and the customer impacts of that. We would like to explore novel analytical techniques and data that help identify indicators of potential evasion in our risking processes.\nWe are seeking solution(s) that can help close the tax gap by identifying deliberate evasion behaviour among small business customers.\nWe are open to exploring a variety of potential solutions that achieve this objective. While not a formal requirement, we anticipate that some solutions will:\n(a)\tIdentify or confirm potential evasion, by predicting behaviour,\n(b)\tExplore different uses of data available to HMRC or third parties.\nFurther information and context on this problem statement is available in the tender documentation.\nThe challenge to identify indicators of evasion:\n•\tThere are an estimated 5.45 million small businesses in the UK (0 to 49 employees).\n•\tSmall businesses operate in all of our main tax regimes: Corporation Tax, VAT, PAYE, Income Tax Self-Assessment.\n•\tSmall business operate across almost all sectors of the economy and evasion can be more prevalent in some sectors and populations than others.\n•\tWe have access to significant amounts of data provided by customers in their tax returns which can be monthly, quarterly, annual and transactional depending on the tax regime.\n•\tWe also have access to some Third Party Data, e.g. Merchant Acquirer data.\n•\tWe use at - scale analytics to detect anomalies as indicators of risk for further investigation.\n•\tAnalysis to detect indicators of behaviour, specifically evasion behaviour, is challenging.\n•\tThis can lead to risk targeting and response being more costly for HMRC and burdensome for the customer.", "status": "active", "items": [ { "id": "1", "additionalClassifications": [ { "scheme": "CPV", "id": "48000000", "description": "Software package and information systems" }, { "scheme": "CPV", "id": "72000000", "description": "IT services: consulting, software development, Internet and support" } ], "deliveryAddresses": [ { "region": "UK", "country": "GB", "countryName": "United Kingdom" } ], "relatedLot": "1" } ], "value": { "amountGross": 6000000, "amount": 5000000, "currency": "GBP" }, "procurementMethod": "open", "procurementMethodDetails": "Competitive flexible procedure", "procedure": { "features": "The competition is being run via HMRC's SAP Ariba portal - see instructions under Submission for how to register for the event.

The event is open to all suppliers and all tender documentation is provided on the portal.\n5.3\tStage 1: Invitation to submit initial tender\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 20 'How to respond to this opportunity' 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 both of the two questions above. The supplier should note that the transcript must answer both questions detailed above, 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. Suppliers not invited to stage 2 will be provided with written feedback on why they have not been shortlisted to participate in stage 2.\n(k)\tSuppliers successfully shortlisted to participate in stage 2 will be issued with a contract based on the template in Attachment E - Contracts for Innovation - Draft Version and Attachment F - HMRC Mandatory Clauses - Draft Version to support their engagement through stage 2.\n(l)\tHMRC intends to shortlist a maximum of 12 suppliers to participate in stage 2.\n(m)\tHMRC may, at its discretion, invite a bidder to form a partnership or consortium with another competitor.\n(n)\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.\n5.4\tStage 2: Solution presentation & demonstration\n(a)\tStage 2 will commence with the issuing of a letter inviting suppliers that have been successfully shortlisted at stage 1 to further develop their proposed solution for a period of approximately 5 weeks.\n(b)\tThe letter will provide details of how the presentation and demonstration stage will be conducted, including the evaluation criteria and process and the format of the presentation event.\n(c)\tThe letter will also provide details of any new information made available to suppliers at this stage of the Procurement.\n5.5\tStage 3: Pilot\n(a)\tStage 3 will commence with the issuing of a letter inviting suppliers that have successfully passed the downselect at stage 2 to participate in a Pilot stage. This stage will allow suppliers to design, build, test and demonstrate their prototypes in consultation with HMRC.\n(b)\tThe letter will provide details of how the prototyping and proof of concept stage will be conducted. HMRC anticipates that the Pilot will have a 12 month duration, and funding will be available for up to 3 bidders. The funding available is capped for stage 3, and HMRC does not commit to cover any or all of the bidder's costs for participating in any stage of this competition. HMRC reserves the right to withdraw any funding offer at any time throughout this competition and makes no guarantee as to its availability.\n(c)\tStage 3 will conclude with the issuing of a letter to all participating suppliers confirming the closure of the Pilot stage.\n5.6\tStage 4: Final tender\n(a)\tStage 4 will commence with the issuing of a letter at the end of stage 3 inviting suppliers that successfully passed the downselect at stage 2 to submit their final tenders.\n(b)\tThe letter will provide details of how the final tender stage will be conducted.\n(c)\tThe letter will also provide details of any new information made available to bidders at this stage of the competition.\n5.7\tOptional stages & rights\n(a)\tHMRC reserves the right to add an optional dialogue or negotiation stage within, or at the end of stage 4. Any use of a dialogue or negotiation stage will be followed by an additional final tender submission. If used, this stage will be described in the letter issued at the beginning of stage 4.\n(b)\tHMRC reserves the right to re-run or re-start any stage of the competition at any time.\n(c)\tHMRC reserves the right to directly award a contract at any stage during the competition if only a single supplier enters or meets the requirements." }, "mainProcurementCategory": "goods", "aboveThreshold": true, "submissionMethodDetails": "This procurement will be conducted by way of an eSourcing event using HMRC's SAP Ariba eSourcing Portal.

The event is open to all suppliers and all tender documentation is provided on the portal.\n5.3\tStage 1: Invitation to submit initial tender\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 20 'How to respond to this opportunity' 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 both of the two questions above. The supplier should note that the transcript must answer both questions detailed above, 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. Suppliers not invited to stage 2 will be provided with written feedback on why they have not been shortlisted to participate in stage 2.\n(k)\tSuppliers successfully shortlisted to participate in stage 2 will be issued with a contract based on the template in Attachment E - Contracts for Innovation - Draft Version and Attachment F - HMRC Mandatory Clauses - Draft Version to support their engagement through stage 2.\n(l)\tHMRC intends to shortlist a maximum of 12 suppliers to participate in stage 2.\n(m)\tHMRC may, at its discretion, invite a bidder to form a partnership or consortium with another competitor.\n(n)\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. \n5.4\tStage 2: Solution presentation & demonstration\n(a)\tStage 2 will commence with the issuing of a letter inviting suppliers that have been successfully shortlisted at stage 1 to further develop their proposed solution for a period of approximately 5 weeks.\n(b)\tThe letter will provide details of how the presentation and demonstration stage will be conducted, including the evaluation criteria and process and the format of the presentation event.\n(c)\tThe letter will also provide details of any new information made available to suppliers at this stage of the Procurement.\n5.5\tStage 3: Pilot\n(a)\tStage 3 will commence with the issuing of a letter inviting suppliers that have successfully passed the downselect at stage 2 to participate in a Pilot stage. This stage will allow suppliers to design, build, test and demonstrate their prototypes in consultation with HMRC. \n(b)\tThe letter will provide details of how the prototyping and proof of concept stage will be conducted. HMRC anticipates that the Pilot will have a 12 month duration, and funding will be available for up to 3 bidders. The funding available is capped for stage 3, and HMRC does not commit to cover any or all of the bidder's costs for participating in any stage of this competition.

The event is open to all suppliers and all tender documentation is provided on the portal.\n5.3\tStage 1: Invitation to submit initial tender\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 20 'How to respond to this opportunity' 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 both of the two questions above. The supplier should note that the transcript must answer both questions detailed above, 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. Suppliers not invited to stage 2 will be provided with written feedback on why they have not been shortlisted to participate in stage 2.\n(k)\tSuppliers successfully shortlisted to participate in stage 2 will be issued with a contract based on the template in Attachment E - Contracts for Innovation - Draft Version and Attachment F - HMRC Mandatory Clauses - Draft Version to support their engagement through stage 2.\n(l)\tHMRC intends to shortlist a maximum of 12 suppliers to participate in stage 2.\n(m)\tHMRC may, at its discretion, invite a bidder to form a partnership or consortium with another competitor.\n(n)\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.\n5.4\tStage 2: Solution presentation & demonstration\n(a)\tStage 2 will commence with the issuing of a letter inviting suppliers that have been successfully shortlisted at stage 1 to further develop their proposed solution for a period of approximately 5 weeks.\n(b)\tThe letter will provide details of how the presentation and demonstration stage will be conducted, including the evaluation criteria and process and the format of the presentation event.\n(c)\tThe letter will also provide details of any new information made available to suppliers at this stage of the Procurement.\n5.5\tStage 3: Pilot\n(a)\tStage 3 will commence with the issuing of a letter inviting suppliers that have successfully passed the downselect at stage 2 to participate in a Pilot stage. This stage will allow suppliers to design, build, test and demonstrate their prototypes in consultation with HMRC.\n(b)\tThe letter will provide details of how the prototyping and proof of concept stage will be conducted. HMRC anticipates that the Pilot will have a 12 month duration, and funding will be available for up to 3 bidders. The funding available is capped for stage 3, and HMRC does not commit to cover any or all of the bidder's costs for participating in any stage of this competition. HMRC reserves the right to withdraw any funding offer at any time throughout this competition and makes no guarantee as to its availability.\n(c)\tStage 3 will conclude with the issuing of a letter to all participating suppliers confirming the closure of the Pilot stage.\n5.6\tStage 4: Final tender\n(a)\tStage 4 will commence with the issuing of a letter at the end of stage 3 inviting suppliers that successfully passed the downselect at stage 2 to submit their final tenders.\n(b)\tThe letter will provide details of how the final tender stage will be conducted.\n(c)\tThe letter will also provide details of any new information made available to bidders at this stage of the competition.\n5.7\tOptional stages & rights\n(a)\tHMRC reserves the right to add an optional dialogue or negotiation stage within, or at the end of stage 4.
