When is the next MTD quarterly update due? 7 November 2026 — here's what it has to contain

Last verified: 24 August 2026, against the cited gov.uk and HMRC sources.

Who this deadline applies to

MTD for Income Tax started on 6 April 2026 for individuals registered for Self Assessment whose qualifying income — total gross income from self-employment and property combined, before any expenses — was over £50,000 in 2024-25. HMRC reminded over 864,000 sole traders and landlords about the first quarterly update, which was due by 7 August 2026 (gov.uk news, July 2026). The phase-in continues: over £30,000 in 2025-26 brings you in from 6 April 2027, and over £20,000 in 2026-27 from 6 April 2028 (gov.uk: check if you need to use MTD).

Two details about qualifying income catch people out (gov.uk: work out your qualifying income): it is the combined total — £25,000 of rent plus £27,000 of self-employment turnover is £52,000 and over the threshold, even though neither source is over it alone — and it is before expenses, so a landlord with £55,000 of rent and £30,000 of costs still has £55,000 of qualifying income.

Why "cumulative" is genuinely good news

Each quarterly update is a set of totals per category covering the period from the start of the tax year to the end of the update period. Update 1 covered months 1–3; the 7 November update covers months 1–6; update 3 covers months 1–9; update 4 the whole year. HMRC's technical documentation confirms each submission supersedes the one before it (HMRC end-to-end service guide).

The practical consequence: if you made a mistake in your 7 August submission, you do not file an amendment. Correct the row in your records, and the 7 November cumulative update automatically carries the fix. Estimated or provisional figures are acceptable in-year, as long as they are corrected by the time you finalise your return (gov.uk).

The update is not a mini tax return. HMRC does not receive your individual receipts or invoices — just the running totals per category. And if you have both a trade and a rental property, you send an update for each income source, though both can be done in the same sitting.

Standard or calendar periods — same deadline either way

The calendar-quarters election exists for people whose books naturally run to month ends. It changes only the period boundaries, never the deadlines — and it had to be selected in your software before your first update of the tax year, so for 2026-27 the choice is already locked in (gov.uk). After the four updates, the year finishes the familiar way: the tax return for 2026-27, submitted through software with your year-end adjustments and other income, is due 31 January 2028, along with payment (gov.uk: submit your tax return).

Yes, a spreadsheet is still legal — with bridging software

You do not need an accounting-app subscription for MTD. HMRC's guidance explicitly permits keeping digital records in a spreadsheet and connecting it to HMRC through bridging software, provided the link between them is digital — you must not re-type totals by hand into a submission screen; corrections are made in the spreadsheet and flow through the digital link (gov.uk: create digital records).

The digital record itself is simpler than the myths suggest: for each item of business income or expense, HMRC requires the amount, the date, and the category. One spreadsheet row per transaction meets the requirement. Bridging software works by cell-mapping — you point it once at the cells holding each category total, and each quarter it reads the current values and submits them. Vendor pricing starts around £30 + VAT per year (VitalTax's published price for one taxpayer, first submission free), and gov.uk confirms free products exist for simple tax affairs, though they may be limited. The authoritative list is HMRC's own software finder.

Two simplifications worth knowing (gov.uk): if your turnover is under £90,000, HMRC accepts a single consolidated-expenses total per update instead of a category-by-category breakdown — though residential landlords must still record restricted finance costs (typically mortgage interest) separately. And retailers can record daily gross takings rather than every individual sale.

What if you miss 7 November?

For the 2026-27 tax year, HMRC has confirmed there are no penalties for missing a quarterly update deadline — a deliberate first-year easement. You must still send the update before you can complete your year-end return, so catch up promptly rather than letting updates stack (gov.uk: penalties for MTD for Income Tax).

From then on, the points system applies: each missed quarterly update or return deadline earns 1 penalty point (one point per deadline, even if several businesses' updates are late together); at 4 points you get a £200 penalty, and a further £200 for each additional miss while at the threshold. Points expire after 24 months if you stay below the threshold. MTD Income Tax points are separate from any VAT penalty points.

Readiness checklist for 7 November 2026

1. Records complete to the period end — every business transaction from 6 April 2026 to 5 October 2026 (or 30 September under the calendar election) logged with amount, date and category.
2. Q1 corrections made in the records, not patched in software — the cumulative update carries them automatically.
3. Categories match HMRC's — MTD uses the same categories of income and expenses as Self Assessment; HMRC's developer APIs define the exact fields (Self Employment Business API, Property Business API).
4. One update per income source — trade and property are submitted separately.
5. Bridging tool connected and mapped — if you cell-mapped it for Q1, the same mapping serves all year.
6. Reconcile before sending — check that every logged amount actually reached a category total; a typo'd category that silently drops out of your totals is the classic spreadsheet failure.

Quick answers

Do I pay tax on 7 November?

No. Quarterly updates are information only. Tax payment dates are unchanged: 31 January, and 31 July if payments on account apply (gov.uk deadlines).

My income is under £50,000 — can I ignore this?

For now. But the threshold falls to £30,000 (tested on your 2025-26 return, mandation from April 2027) and £20,000 (from April 2028) — and it's combined gross income, not profit.

Can I get out of MTD entirely?

If you're digitally excluded, you can apply to HMRC for an exemption by phone or post; HMRC aims to respond within 28 days (gov.uk: apply for an exemption).

Do the figures have to be accurate to the penny?

In-year updates can include estimated or provisional amounts; what matters is that the final figures on your tax return are right.
