In March 2025, the Government published a tax consultation on the use of third-party data which ran until 21 May 2025. The premise? To “help taxpayers get their tax right the first time, whilst closing the tax gap”.
In practice, the idea is that HMRC will put increased focus on improving the quality of certain data already gathered from organisations, so that it can automatically be factored into the individual’s personal tax account, ultimately reducing the administrative burden on the taxpayer and lessening the scope for non-compliance.
The consultation focused on financial account information (specifically bank and building society interest (BBSI)) and other interest – and card sales (data shared by providers of card acquiring services such as merchant acquirers).
But how does this differ from what we already have in place? And what could it mean for the future of income tax in the UK?
