Making Tax Digital for Income Tax will become mandatory in phases from April 2026. If you are self-employed or a landlord earning over £50,000 you need to start preparing to submit quarterly updates, keeping digital records and a new penalty system will apply.

Initially, MTD for IT will apply to businesses, self-employed individuals, and landlords with an annual income exceeding £50,000. From 6 April 2027, the rules will extend to those with an income between £30,000 and £50,000. A new system of penalties for late filing and late payment of tax will also be introduced.

From April 2028, sole traders and landlords with income over £20,000 will need to follow MTD rules. The government is also exploring ways to bring those earning under £20,000 within the MTD framework at a future date.

To help ensure taxpayers pay on time, HMRC increased the late payment penalties with effect from 1 April 2025. This applies to VAT-registered businesses as well as early adopters of Making Tax Digital for Income Tax.

The updated penalty rates are as follows:

• 15 days late: increased from 2% to 3%
• 30 days late: increased from 2% to 3%
• From day 31 onwards: a 10% annual penalty now applies, up from 4%, with daily interest added from this point

Taxpayers that remain with self-assessment face a separate set of penalty rules.
