If you’re a sole trader or landlord earning over £50,000 who’s been keeping digital records under Making Tax Digital for Income Tax since April, it’s worth being precise about what happens next. The period covering 6 April to 5 July 2026 has closed — but closing a reporting quarter isn’t the same as submitting it. The actual deadline to send that first quarterly update to HMRC is 7 August 2026, a full month after the quarter ends. Recent research surveying 1,000 UK sole traders earning £50,000-plus found that 55% said they still had work to do before they’d be ready — which, with under three weeks to go, is a lot of businesses cutting it fine on a legal deadline that’s genuinely new to them.

Why the confusion is common

Under the old annual Self Assessment system, there was one filing point a year, so it’s an easy habit to assume “the quarter’s over” means “I’m done.” MTD for Income Tax doesn’t work that way. You keep digital records throughout the quarter using compatible software, then submit a summary of income and expenses for that period within roughly a month of it closing. Miss 7 August, and you’ve missed a statutory submission, not just a personal deadline — even though HMRC has confirmed there are no penalties for missed quarterly updates during this first 2026/27 transition year. That soft-landing is real, but it’s not permission to ignore it: you still have to catch up your digital records and file the update eventually, and penalties do start applying in later years once the transition period ends.

What to check before 7 August

Confirm two things this week. First, that your bookkeeping software is actually MTD-compatible and connected to HMRC — not just any spreadsheet or accounting tool, but one on HMRC’s recognised list, submitting the specific quarterly summary format required. Second, that your April-to-July income and expenses are fully entered, not partially logged with the rest “to catch up later.” If you’ve been putting receipts in a shoebox and planning to reconstruct the quarter from memory in early August, that’s exactly the scenario the 55%-not-ready statistic is describing.

If your bookkeeping has genuinely fallen behind, this is also a reasonable moment to ask whether it’s worth automating the parts that keep slipping — bank feed reconciliation, receipt capture, expense categorisation — rather than doing it manually every quarter under deadline pressure. That’s squarely the kind of practical, contained project BuildApps or CoolCoding can help set up properly once, rather than you rebuilding the same time pressure four times a year.

It gets easier after the first one

Most of the friction in this transition is genuinely first-quarter friction. Once your software is properly connected and your record-keeping habit is established, quarters two, three, and four tend to be far less work than the first — you’re maintaining a routine rather than building one from scratch under deadline pressure. That’s a reasonable thing to tell yourself if this feels disproportionately stressful right now: it front-loads the effort, it doesn’t repeat it. But that only holds if the connection and the habit actually get built properly this time, rather than scraped together once and abandoned until the next quarter’s deadline creeps up in the same way.

The takeaway

5 July was the end of your first MTD quarter, not the finish line. The actual submission deadline is 7 August 2026, and with over half of eligible sole traders telling researchers they weren’t ready as of this month, it’s worth confirming today — not in the last week of July — that your software is connected, your records are complete, and you know exactly what you’re submitting and when.
