Proposed changes to the basis period rules, which are currently being consulted on, could result in some self-employed businesses being mandated into Making Tax Digital for Income Tax sooner than expected.

Making Tax Digital for Income Tax

Based on the current draft regulations, Making Tax Digital for Income Tax Self Assessment (MTD ITSA) will compulsorily apply for accounting periods starting on or after 6 April 2023.

Consultation: basis period reform

HMRC recently published a Consultation, policy paper and draft legislation proposing a simplification of the Income Tax rules for the self-employed by allocating trading profit to tax years regardless of the business’ accounting period end date.

If the Basis period reforms being consulted on go ahead, existing traders with a 31 March accounting period end could be mandated into MTD ITSA a year earlier than they may have expected. MTD ITSA would apply from 6 April 2023, rather than 1 April 2024.

For a trader with a 31 March year-end:

This impact is not limited to traders with an accounting period ending on 31 March. Under the draft regulations, traders would have expected to join MTD ITSA at different dates depending on their accounting end date, for example:

In all cases, under the basis period reform, as currently proposed, the MTD ITSA start date is likely to become 6 April 2023.
