Staying on top of your Making Tax Digital (MTD) deadlines is vital for avoiding HMRC penalties and keeping your business fully compliant with the UK’s digital tax rules. Whether you’re filing VAT returns, submitting quarterly income tax updates, or preparing for future Corporation Tax requirements, knowing when to file is just as important as how to file.

This guide breaks down the key MTD deadlines for 2025 and beyond, organised by tax type, so you always know what’s due and when.

MTD for VAT: Deadlines

If you’re VAT-registered, MTD for VAT applies to you, and your digital VAT returns must be submitted on time via compatible software.

If you’re VAT-registered, MTD for VAT applies to you. You must submit your digital VAT returns on time through MTD-compatible software — late filing or payment can lead to penalties and interest charges.

When are MTD VAT returns due?

  • Filing deadline: One month and seven days after the end of your VAT period.
  • Payment deadline: Same as your filing deadline — one month and seven days after the VAT period ends.

Example:
If your VAT quarter ends on 31 March, your MTD VAT return and payment are both due by 7 May.

VAT Quarter EndsFiling & Payment Deadline
31 March7 May
30 June7 August
30 September7 November
31 December7 February (following year)

If you file monthly or annual VAT returns, the same rule applies your deadline is always one month and seven days after the end of your VAT period.

MTD for Income Tax (ITSA): Deadlines

Making Tax Digital for Income Tax Self-Assessment (MTD for ITSA) is due to start in April 2026, beginning with self-employed individuals and landlords with annual income over £50,000.

Under MTD for ITSA, you’ll have new deadlines to meet throughout the year:

  • Quarterly updates: Submitted every three months to HMRC using MTD-compatible software.
  • End of Period Statement (EOPS): Submitted after your accounting year ends to finalise income and claim any reliefs.
  • Final Declaration: This replaces the traditional Self-Assessment tax return and must be submitted by 31 January following the end of the tax year.

Quarterly Update Schedule (from 2026):

QuarterPeriod CoveredSubmission Deadline
Q16 April – 5 July5 August
Q26 July – 5 October5 November
Q36 October – 5 January5 February
Q46 January – 5 April5 May

Your final declaration and any balancing tax payment remain due by 31 January after the end of the tax year, just like the current Self-Assessment deadline.

MTD for Corporation Tax: What Happened to the Timeline?

Making Tax Digital for Corporation Tax (MTD for CT) was originally planned for rollout no earlier than April 2026, following consultations and pilot schemes. However, the UK government has since confirmed that MTD for CT will not be introduced.

Here’s how the timeline developed before the decision was made:

YearEvent
2021HMRC completed its consultation on MTD for Corporation Tax
2024Pilot scheme tested digital submissions with volunteer companies
2025Government confirmed MTD for Corporation Tax will not go ahead

Key point: Companies will continue filing Corporation Tax returns through the current CT600 system. While MTD for CT is off the table, moving to digital record-keeping and accounting software is still strongly recommended to improve accuracy, save time, and prepare for any future HMRC updates.

Accounting Wise - What Happens If You Miss an MTD Deadline?

What Happens If You Miss an MTD Deadline?

HMRC now uses a points-based penalty system for late MTD submissions, replacing the old single-penalty approach. Here’s how it works:

  • You get one point each time you miss a submission deadline.
  • Once you reach a points threshold for example, four points for quarterly VAT returns you’ll receive a £200 fine.
  • After that, each additional missed deadline triggers another £200 penalty until you bring your points back down.

Points expire after 12 months of full compliance, so submitting on time consistently will reset your record and help you avoid repeat fines.

Keeping digital records up to date and using reminders in your MTD software makes it much easier to stay compliant and avoid penalties.

Making Tax Digital Deadlines FAQs

The main MTD deadlines are:

  • April 2022 – MTD for VAT became mandatory for all VAT-registered businesses, regardless of turnover.
  • April 2026 – MTD for Income Tax Self Assessment (ITSA) will begin for self-employed individuals and landlords with income over £50,000.
  • April 2027 – MTD for ITSA is expected to extend to those earning between £30,000 and £50,000.

If you are VAT-registered, you must already be using MTD-compliant software to keep records and file VAT returns digitally. This became mandatory in April 2022 and applies to all VAT-registered businesses, including those below the £85,000 turnover threshold.

MTD for ITSA begins in April 2026 for self-employed individuals and landlords with annual income over £50,000. Those earning between £30,000 and £50,000 are expected to join in April 2027. HMRC has not yet set a date for businesses earning under £30,000.

Under MTD for ITSA, businesses will need to submit digital updates every quarter, instead of a single annual tax return. The reporting periods are expected to be:

  • 6 April to 5 July → report due 5 August
  • 6 July to 5 October → report due 5 November
  • 6 October to 5 January → report due 5 February
  • 6 January to 5 April → report due 5 May

These dates will be confirmed closer to rollout.

Not yet. If you’re not VAT-registered, MTD doesn’t apply to you unless you are self-employed or a landlord and fall into the ITSA thresholds starting in 2026. However, moving to digital software now will make the transition smoother and reduce stress later.

No it has been cancelled. The government confirmed in 2025 that MTD for Corporation Tax will not go ahead. Companies will continue filing Corporation Tax returns using the CT600 form via HMRC’s online system.

Missing deadlines could mean:

  • Late submission penalties
  • Interest charges on unpaid tax
  • Potential compliance checks from HMRC
    Using digital software reduces the risk of missing deadlines, as many tools include automated reminders and direct submission features.

To stay on top of deadlines:

  • Use MTD-compliant accounting software with deadline alerts
  • Work with an accountant who monitors filing dates for you
  • Keep digital records updated regularly instead of leaving it until year-end

At Accounting Wise, we manage digital record-keeping and submissions on your behalf, ensuring you never miss an MTD deadline.
