Your MTD IT Survival Guide | Be Ready for 7 August 2026

A practical guide for accountants and bookkeepers who need to get their practice ready for the 7th August 2026 MTD for Income Tax quarterly filing deadline.

A guide to the first Making Tax Digital filing deadline for accountants

This guide is for practices that need to be ready for the 7th August 2026, the first MTD for Income Tax quarterly filing deadline. It covers what compliance actually looks like in practice, what tools you need, and what to do between now and deadline day.

Since April 2026, self-employed individuals and landlords with qualifying income over £50,000 are legally required to keep digital records and submit quarterly updates to HMRC. Many practices are still stuck in preparation mode, and the clock is already running.

The good news is that August is also an opportunity. Practices that handle this well will strengthen client relationships and stand out from those that don’t. Getting MTD right is not just about compliance; it is about showing clients they are in safe hands.

Frequently Asked Questions about MTD for Income Tax

What is the first MTD for Income Tax quarterly filing deadline?

The first quarterly filing deadline is 7 August 2026. It covers Quarter 1 of the 2026/27 tax year, which runs from 6 April to 5 July 2026. All self-employed individuals and landlords with qualifying income over £50,000 who entered MTD from April 2026 must submit by this date.

What counts as MTD-compatible software?

MTD-compatible software is any HMRC-recognised digital tool that can keep digital records and submit quarterly updates directly to HMRC. HMRC publishes its approved software list on GOV.UK. BrightBooks is on that list and supports direct quarterly submission for all client types.

Do my clients need to change the software they use for bookkeeping?

Not necessarily. BrightBooks includes bridging tools for clients who want to keep using Excel, so they can stay MTD-compliant without changing how they work day to day. For clients already using Xero, QuickBooks, or Sage, BrightTax pulls quarterly data directly from HMRC for the annual declaration, so no migration is needed.

What happens after the 7 August deadline?

The quarterly cycle continues. The remaining deadlines for 2026/27 are 7 November 2026, 7 February 2027, and 7 May 2027, with a final declaration at year end. From April 2027, the income threshold drops to £30,000, bringing a larger and generally less digitally prepared cohort of clients into scope.

What is the penalty for missing the MTD quarterly filing deadline?

HMRC has confirmed a soft-landing approach for 2026, so penalties may not be applied immediately in the first year. But the obligation to file is live, and missing or inaccurate quarterly data creates extra work when it comes to the final declaration. Filing on time from Q1 is strongly advisable.
