The mandatory rollout of Making Tax Digital for Income Tax (MTD for ITSA) is scheduled to begin in April 2026. The process will significantly adjust how businesses, self-employed individuals, and landlords engage with HMRC. The system will require businesses and individuals to register, file, pay, and update their details through an online tax account.

It is important to begin to consider using accounting software that is equipped to send updates to HMRC in preparation for the launch of MTD for ITSA in April 2026.

According to HMRC, the software must be capable of:

• creating and storing digital records of your business income and expenses — you can choose to use spreadsheets with compatible software to do this;
• sending quarterly updates;
• submitting your tax return by 31 January after the end of the year; and
• receiving information from HMRC.

The MTD for ITSA rules will initially apply to businesses, self-employed individuals and landlords with an income of over £50,000 annually. MTD for ITSA will then be extended to those with an income between £30,000 and £50,000 from 6 April 2027. A new system of penalties for the late filing and late payment of tax for ITSA will also apply. At present there are no plans to extend ITSA to smaller businesses with income below £30,000 or to Corporation Tax.

Readers affected by this forthcoming change who have not yet converted to the use of an MTD compatible accounting software should consider their options, and we can help. Please call.
