UK tax-data outcome sets out 21-day reporting deadline

What the consultation outcome says

On 29 October HMRC published the outcome of its technical consultation on improved third-party tax data. The government says it amended the proposed regulations and guidance after industry feedback, including clearer requirements and a 21-day reporting deadline. It plans to lay the regulations on 3 November 2026 and publish updated schemas, guidance and the impact note on the same date. Official source.

The planned reporting framework

The consultation concerns interest-income data and card-sales data, including relevant banks, building societies, merchant acquirers and payment facilitators. The framework sits under Schedule 23 of the Finance Act 2026. The outcome retains preparation for reporting from April 2028. The short outcome statement does not supply every operational detail needed to calculate an individual reporting deadline or build a compliant production system.

Do not build solely from the old draft

Earlier consultation documents discuss collecting and verifying tax references, obtaining missing information and reporting on an ongoing basis. The outcome says revised material will follow. Data holders should therefore version-control the documents they use and compare the forthcoming rules and schemas with the consultation drafts. A design based on an earlier assumption about timing or required fields may need to change.

A clearly hypothetical example

A payment facilitator starts designing a card-sales reporting process using the July draft schema. Following the October outcome, it should reserve a review point for the 3 November publication and test how the final deadline interacts with validation, correction and submission. It should not tell customers that every draft field is already a final legal requirement simply because software development has begun.

Data quality and access need planning together

The useful preparation is to map where required information originates, how identity or tax references will be checked, who can access records and how errors will be corrected. Collecting additional data without a defined purpose can create avoidable privacy and operational problems. The outcome also says further work will address registration and arrangements for amendments or resubmission, so those areas remain important dependencies.

What to monitor next

Check the legislation laid on 3 November and the accompanying final guidance before settling implementation commitments. Record unresolved questions about scope, frequency, deadline triggers and correction procedures, then assign responsibility for resolving them. This is a consultation outcome and implementation milestone, not evidence that April 2028 reporting is already live or that a particular customer’s tax position has changed.
