Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what steps her Department will take to ensure transparency in the operation of HMRC's proposed whistleblowing reward scheme; and whether she plans to publish (a) eligibility criteria and award thresholds for applicants, and (b) data on the number and value of awards granted.

At Autumn Budget on 26 November 2025 the Government launched the Rewards for informants of high value tax fraud. This scheme is designed to target serious non-compliance involving large corporates, wealthy individuals, offshore and avoidance schemes. Informants can receive a reward of between 15 and 30% when they provide information which leads directly to HMRC collecting more than £1.5M tax. HMRC have published eligibility criteria for the scheme at https://www.gov.uk/guidance/reporting-serious-tax-avoidance-and-evasion.

HMRC has previously published data on the total amount of rewards paid annually through the standard informants reward scheme and will continue to do so. To protect the confidentiality of informants we do not publish the number of rewards or size of individual rewards.
