Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what measures she is taking to help ensure all landlords declare their rental income accurately.

HMRC seeks to promote compliance and prevent non-compliance as early as possible through targeted education and support. We use a range of data sources and other information to identify, deter, and respond to non-compliance in the property sector, and help landlords to get their tax right from day one, keep them on track, and offer an opportunity to address previous errors.

Where landlords do not come forward to correctly declare their rental income, HMRC takes further steps including opening formal compliance interventions where necessary. We respond strongly to those who deliberately bend or break the rules.

From April 2026, landlords with qualifying income above £50,000 will need to use Making Tax Digital (MTD) for Income Tax. That threshold will reduce to £30,000 in April 2027 and £20,000 in April 2028.

MTD helps taxpayers pay the right amount of tax by encouraging timely and accurate record keeping, with digital prompts (where supported) pointing out errors or missing entries.

Through reducing error and improving accuracy in returns, MTD is expected to raise around £3bn in additional tax revenue by 2030-31.
