MTD Quarterly Update Checklist: Get Your 7 November Update Right

The first Making Tax Digital quarterly update deadline came and went on 7 August 2026. If yours was a scramble — or did not happen — the good news is structural: updates are cumulative, so the one due on 7 November covers the whole tax year to date and closes any Q1 gap at the same time.

This is the working checklist for that update and every one after it. For the regime as a whole — who is in, when, and what the Final Declaration is — see the Making Tax Digital guide.

Key Takeaways

• The Q2 update covers 6 April to 5 October 2026 and is due 7 November 2026 (calendar-quarter election: 1 April to 30 September, same deadline)
• Each update is cumulative — year to date, not the last three months — so a missed Q1 is satisfied by Q2
• HMRC receives totals per income and expense category, not individual transactions
• No accounting or tax adjustments are needed — the update is a summary, not a return, and no tax is due on it
• No penalty points for late updates in 2026/27. From 2027/28, four late submissions triggers £200
• The real work is upstream: every transaction in the period must exist as a digital record before you send

The Deadlines, Both Ways of Counting

Notice the start date never moves. That is the cumulative design: Q2 is not "July to September", it is "everything since the tax year began". If your first update was late, thin, or absent, the second one replaces it in HMRC's view of the year.

One constraint on the election: you cannot switch between standard and calendar periods for a tax year once you have sent an update. Whichever you used (or your software used) for Q1 is fixed until 6 April 2027.

What HMRC Actually Receives

A quarterly update is a set of totals per category, matching Self Assessment categories, for each business — self-employment, UK property and foreign property each file separately.

It is not:

• A tax return. No tax is calculated or due. Your software shows an estimate afterwards; that is informational
• A transaction list. HMRC's own wording is that it "will not receive details of individual digital records, such as a receipt or invoice"
• Adjusted figures. HMRC states you "do not need to make any accounting or tax adjustments before sending a quarterly update" — no capital allowances, no private-use apportionment, no accruals. Those come at the Final Declaration

If your turnover for an income source is under £90,000, the update can be a single income total and a single expense total rather than a category breakdown. Above it, categories in full. The digital records guide covers what each underlying record must contain.

Four Weeks Out — Reconciliation Checklist

Aim to have this done by 10 October for a 7 November deadline. Everything here is about making sure the digital records exist and are right; the submission itself is minutes.

• Confirm which update periods you are on (standard or calendar) — check what Q1 was sent under; it cannot change now
• Bank feed complete to the period end — every business account and card connected or statements imported through 5 October (30 September on the calendar election)
• Every bank line categorised — or, under £90k, at least marked income or expense
• Receipts matched to bank lines — each cost has its evidence attached or filed, so the record and the receipt are linked before quarter end rather than reconstructed later
• Off-feed costs captured — anything paid in cash, on a personal card, or by direct debit from a personal account. These are the entries a bank feed never reminds you about
• Email receipts pulled in — software subscriptions, online orders, travel bookings; connect the inbox rather than forwarding one by one
• Income recorded on the right basis — invoices paid, not invoices raised, if you are on cash basis (the default for most sole traders); rent received for landlords
• Q1 gaps filled — anything missed before 7 August simply goes in now; the cumulative total takes care of it
• Separate businesses separated — self-employment and property records are not mixed; UK and foreign property are separate businesses
• Jointly owned property handled per owner — your share only; expenses can be deferred to the annual submission for jointly let property. See the landlords guide
• Agree who submits — if your accountant sends the update, confirm they have what they need and by when; if you send it, confirm the filing product still connects to HMRC

The Week Of — Submission Checklist

• Records exist for every transaction to the period end. This is the rule that matters: digital records must be in place before the deadline or before you send, whichever is first
• Totals sanity-checked against last quarter's cumulative figures — Q2 totals should be Q1 plus three months, not a fresh three months
• Category totals look plausible — a quarter with zero motor costs for a tradesperson, or expenses larger than turnover, is worth a second look before sending, not after
• Digital link intact — if your records live in one product and your filing in another, the export was CSV/API/integration, not retyped totals
• Send. Then note the estimated tax figure your software shows — it is a rough guide to what to set aside, nothing more
• Diarise 7 February immediately

If You Missed 7 August

Send the Q2 update by 7 November and you have met the obligation for both quarters — the cumulative total does the work.

On penalties: HMRC has confirmed no penalty points for late quarterly updates during 2026/27. In later years each late update earns a point and four points triggers £200 (two points if you volunteered in early). Late payment penalties on tax are a separate matter and are unaffected by the concession. Detail in the MTD penalties guide.

What the concession does not cover: you still need to send the updates before you can file the year's return, and a late annual return still earns a point this year. Treat 2026/27 as the year to get the rhythm right without the cost, not the year to skip it.

Common Q1 Mistakes to Fix Before Q2

From the first cycle, the errors that come up most often — none of them fatal, all of them easier to fix now than in January:

1. Recorded the last three months instead of year to date. Q2 should carry the cumulative total. If your software builds the update from the records it holds, this is automatic; if you keyed totals into bridging software, check what you keyed.
2. Missed off-feed costs. Personal-card subscriptions, cash purchases, the parking meter. Add them now; the cumulative total picks them up.
3. Adjusted the figures. Deducting private use, applying capital allowances or simplified expenses before the update. Not needed and not wanted — those are Final Declaration adjustments.
4. Mixed businesses. Property expenses in the trade, or foreign property in with UK. Each is its own update.
5. Retyped totals into the filing product. Compliant records, broken digital link. Fix the workflow (export or connect) so it does not repeat.
6. Assumed the record-keeping app files. A tool that holds your receipts and records is not necessarily one HMRC recognises for submission. Know which product in your setup actually sends — see the MTD software guide.

Correcting a Sent Update

• During the tax year: fix the underlying record and the next update carries the correction. There is no separate amendment; the cumulative Q3 total simply overwrites what Q2 said.
• After Q4: resend the fourth update, or adjust the category totals in your software — before you make any tax adjustments for the Final Declaration.

If your accountant files for you, tell them what changed rather than fixing it silently — they will be reconciling your records to the update they sent.

Making Q3 Boring

The reason Q1 was a scramble for a lot of people is that the deadline arrived and the records did not exist yet. The fix is not a better checklist; it is moving the record-keeping to the point where the transaction happens:

• Capture receipts on the day — photograph paper, let email receipts pull in automatically. Each becomes a digital record with amount, date and merchant already filled in
• Match bank lines weekly, not quarterly — ten minutes a week versus a lost Sunday in October
• Export digitally into your filing product — an integration or a CSV, so the digital link is never in question

That is the split MTD-ready record keeping is designed for: SparkReceipt keeps the digital records and the evidence behind them, up to date as costs happen; your HMRC-recognised software turns them into the update. When 7 February comes round, the checklist above should take an afternoon at most.

MTD Quarterly Update FAQ

What is a quarterly update for MTD?

A summary of your business income and expenses, sent to HMRC through MTD-recognised software four times a year. It contains totals per category for the tax year to date. It is not a tax return and no tax is due on it.

When is the next MTD quarterly update due?

7 November 2026, covering 6 April to 5 October (or 1 April to 30 September on the calendar-quarter election). Then 7 February and 7 May.

What if I missed the 7 August deadline?

Send the 7 November update. Because updates are cumulative it covers both quarters. HMRC is not applying penalty points to late quarterly updates in 2026/27.

Do I need to send receipts with the update?

No. HMRC receives category totals only. You must keep the receipts as evidence for at least 5 years after the 31 January deadline, and the digital records behind the totals must exist before you send.

Do I make tax adjustments in the quarterly update?

No. HMRC's guidance says no accounting or tax adjustments are needed before sending. Adjustments belong to the Final Declaration.

Can I estimate figures in a quarterly update?

The update should reflect the digital records you hold for the period. Errors are corrected in the next update, so an honest figure that later needs revising is fine; a placeholder guess with no records behind it is not what the rule intends.

Can I change from standard to calendar quarters?

Not once you have sent an update for the tax year. The election is fixed until the following 6 April.

Does my accountant have to send the update, or can I?

Either. HMRC allows you, your agent, or a mix — you keep the records, they submit — as long as the data moves between you digitally.
