Self Assessment Tax Return

If Self Assessment is on your to-do list this year, you’re in the right place.

Whether you’re a sole trader, landlord, or both, every tax year still ends the same way: with a final Self Assessment tax return that needs to be accurate, compliant, and submitted on time.

That hasn’t changed - even with Making Tax Digital.

How MTD fits in

From 6 April 2026, HMRC will begin rolling out Making Tax Digital for Income Tax Self Assessment (MTD for ITSA). Over time, this means more frequent reporting during the year for some taxpayers.

But here’s the bit most people care about:

👉 You’ll still need a final declaration at the end of the tax year.

That’s the return that:

  • Confirms your total income and expenses

  • Finalises your tax position

  • Makes everything official with HMRC

In other words, the important bit doesn’t go away.
