What is MTD for Income Tax?

Making Tax Digital for Income Tax Self-Assessment (MTD ITSA) is HMRC's requirement that self-employed people and landlords keep digital records and report income quarterly to HMRC rather than once a year through a Self-Assessment return.

The change affects how tax reporting is done rather than how much tax is paid. The same income, expenses and reliefs apply — the difference is that the data must be submitted four times a year using compatible software, with a final declaration at the end.

Who is affected and when?

From April 2026, MTD ITSA is mandatory for self-employed individuals and landlords whose qualifying income (combined gross self-employment and property income) exceeds £50,000 per year.

From April 2027, the threshold drops to £30,000. A further rollout to those with qualifying income above £20,000 has been proposed but not yet confirmed. Partnerships and trusts have separate timelines.

What does the quarterly reporting process involve?

Each quarter, taxpayers must submit a digital update to HMRC summarising income and expenses for that quarter. The quarters follow the business's accounting period, with the option to align to the standard HMRC quarterly periods. Compatible software handles the submission automatically.

At the end of the tax year, an end-of-period statement (EOPS) must be submitted for each source of income — self-employment and property are treated separately. The final declaration then confirms the complete tax position for the year, replacing the traditional Self-Assessment return.

What software is required?

HMRC publishes a list of MTD-compatible software. Popular options include Xero, QuickBooks, FreeAgent and various bookkeeping apps. Free software options are also available for those with simpler affairs.

The software must be able to receive and store digital records throughout the year and submit quarterly updates directly to HMRC. Spreadsheets can be used as the record-keeping tool if bridging software is used to make the digital submission.

The traditional Self-Assessment return is replaced by a final declaration at the end of the year. The information required is broadly the same, but it is submitted through compatible software as the last step in the MTD process.

HMRC's new points-based penalty regime applies to MTD ITSA. Each missed submission adds a penalty point, and once a threshold is reached, a financial penalty is charged. The system is designed to penalise persistent non-filers rather than occasional late submissions.

No. The same tax rules, allowances, deductions and reliefs apply. MTD changes the timing and method of reporting, not the underlying tax liability.

Yes. Countify can review whether MTD applies to you, help you choose and set up compatible software, structure your bookkeeping for quarterly reporting and manage the submission process on your behalf.
