Final Declaration Support for Making Tax Digital
The final declaration is where your quarterly figures become a complete tax return, with other income, gains and reliefs added and your liability confirmed. ABM Chartered Accountants provides final declaration support that files accurately through compatible software before 31 January.
Your Complete Tax Return Under MTD
Final declaration support covers the year-end submission that replaces the Self Assessment return for MTD taxpayers. Once all four quarterly updates are filed, we finalise each business with accounting adjustments, then add employment income, dividends, interest, pension income, capital gains and reliefs such as pension contributions or Gift Aid. Your first MTD final declaration for 2026 to 2027 is due by 31 January 2028.
We prepare the full tax calculation, review it with you for planning opportunities, obtain your approval and submit through your compatible software with confirmation from HMRC.

Why Your Final Declaration Needs an Accountant
All income captured: PAYE, dividends, interest, pensions and gains are added correctly alongside your MTD business figures.
Every relief claimed: Pension contributions, Gift Aid, marriage allowance and loss claims are reviewed before submission.
Accurate liability: Payments on account and the balancing payment are calculated so you know exactly what to pay in January.
Filed before penalties: A late final declaration earns a penalty point and a £200 charge once the threshold is reached.
Planning review included: Year-end is when we identify timing and structuring choices that reduce next year’s bill.

Final Declaration FAQs
Common questions about the final declaration that completes each tax year under Making Tax Digital for Income Tax.
What is the final declaration under MTD?
It is the year-end submission through compatible software that finalises your business figures, adds all other income and reliefs, and confirms your tax liability. It replaces the Self Assessment return.
When is the final declaration due?
By 31 January following the end of the tax year. For the first MTD year, 2026 to 2027, the deadline is 31 January 2028, which is also when the balancing payment is due.
Can I submit before all quarterly updates?
No. HMRC requires all four quarterly updates to be filed before the final declaration is accepted. We check every update is in place before starting your year-end work.
Does the final declaration include employment income?
Yes. Employment income, dividends, savings interest, pension income and capital gains are all added at this stage, together with reliefs such as pension contributions and Gift Aid.
What happens if the final declaration is late?
A late final declaration earns a penalty point. Reaching four points triggers a £200 penalty and each further late submission adds another £200 until you return to compliance.
Do you also handle the tax payment?
We calculate the balancing payment and payments on account, tell you the amounts and dates, and can arrange a time to pay agreement with HMRC if needed.
