The deadline for the 7th November MTD submission is approaching.
For sole traders and landlords who began Making Tax Digital for Income Tax in April 2026, this marks the second quarterly update of the first mandatory MTD year.
October is your last full month to ensure your bookkeeping is accurate, your digital records are complete, and your software is prepared.
Waiting until November to review everything leaves you little time to resolve missing transactions, unreconciled accounts, or software issues.
Use this October checklist to prepare now.
What is the 7th November MTD deadline?
The 7th November MTD deadline is the deadline for the second Making Tax Digital for Income Tax quarterly update of the 2026/27 tax year.
For businesses with standard update intervals, the second update encompasses records from 6 April to 5 October 2026.
For those using calendar-based periods, it covers 1 April to 30 September 2026. HMRC’s current system applies cumulative updates, meaning your second quarterly update includes totals from the start of the tax year through the end of the specified period, not just the last three months.
Your software calculates these totals from your digital records.
Therefore, October is the ideal time to verify the records supporting these figures.
Your October checklist for the 7th November MTD deadline
1. Check that your first quarterly update was submitted
Begin by reviewing your status as of the first MTD deadline on 7th August.
If you’ve already submitted your initial update, focus on preparing the next one.
If you missed the deadline, don’t assume you can skip ahead to November. HMRC mandates that all quarterly updates be submitted prior to filing your tax return.
Contact your bookkeeper now if you have any pending updates.
2. Make sure your digital records are up to date
Your MTD quarterly update is generated from your digital bookkeeping records.
October is a good time to verify that all entries are complete.
Look for:
- Sales and other business income
- Property income, where relevant
- Business expenses
- Property expenses
- Customer invoices
- Supplier invoices
- Bank transactions
- Payments received
- Refunds or credits
HMRC recommends creating digital records as soon as possible after the transaction date.
If you’re regularly updating your books, this should mainly be a review rather than a catch-up effort.
3. Find any missing receipts and invoices
That receipt you planned to handle later? Later is now.
Make sure you have supporting documentation for the transactions recorded during this period.
Missing documentation can make it difficult to understand the purpose of a payment and whether it was recorded accurately.
Pay particular attention to:
- Business purchases made personally
- Online subscriptions
- Fuel and travel costs
- Supplier bills
- One-off purchases
- Refunds
- Customer invoices
Identifying gaps early gives you more time to gather the necessary information.
4. Reconcile your bank accounts
Do your bookkeeping records align with your bank account transactions?
Bank reconciliation helps uncover:
- Missing transactions
- Duplicate entries
- Unmatched customer payments
- Incorrect amounts
- Payments recorded against the wrong invoice
- Transactions entered twice
Just because your bank feed imports transactions automatically doesn’t mean everything is accurate.
The software can import data, but you still must verify it.
5. Check your income has been recorded correctly
Review the income received by your business or property activity.
Ask yourself:
- Have all sales been recorded?
- Are customer payments matched to the correct invoices?
- Have any transactions been duplicated?
- Have refunds been recorded?
- Is property income complete?
- Are there payments sitting in your bank feed that have not been dealt with?
If your income records are incomplete, your quarterly totals may be incomplete too.
6. Review your expenses
Next, review the business’s outgoings.
Ensure expenses are recorded accurately and classified appropriately.
While automated bookkeeping tools may recommend categories based on past transactions, these suggestions can sometimes be incorrect.
For instance, two payments to the same supplier could pertain to entirely different purchases.
If you notice anything unusual, investigate and resolve it before finalising your update. HMRC advises that if you discover an error in your digital records during the year, you should correct it promptly.
7. Check each source of income
If you own multiple businesses or have income from self-employment and property, ensure you know what to report.
Under MTD, you are required to submit quarterly updates for each income source.
For example, you might have:
- One self-employed business
- A second self-employed activity
- UK property income
- Foreign property income
Do not assume a single update covers all sources.
Your bookkeeper can help you understand the proper way to maintain your records.
8. Check your MTD software is still connected
Do not delay addressing software issues until November 7th.
Your compatible software must be authorised and connected to HMRC before it can submit quarterly updates.
During October, check:
- You can access the software
- Your bank feeds are working
- All records are syncing correctly
- Your HMRC connection is active
- You know how the quarterly update will be submitted
If you use a bookkeeper, confirm who will complete the submission.
9. Review anything unusual before the deadline
Not every quarter will have simple transactions.
Perhaps you:
- Bought expensive equipment
- Received a large refund
- Changed bank accounts
- Started receiving property income
- Stopped a business activity
- Received an unusual customer payment
- Made transactions between business accounts
Don’t leave these issues unresolved.
If you don’t understand something, flag it to your bookkeeper for review while there’s still time.
10. Do not wait until 7th November to press submit
7th November is the deadline, not the submission day.
HMRC states that quarterly updates are typically due between the end of the relevant period and the deadline.
Once your records are complete and verified, there’s little benefit in delaying submission until the last minute.
Submitting early allows more time to resolve any technical issues that may arise.
What if you miss the 7 November MTD deadline?
During the 2026/27 tax year, HMRC will not assign penalty points for late quarterly updates.
However, that doesn’t mean the deadline is optional.
You still need to:
- Maintain the required digital records
- Send the quarterly update
- Catch up on any outstanding updates
- Complete all required quarterly updates before submitting your tax return
Starting from tax years after 2026/27, missing quarterly deadlines may lead to penalty points.
Accumulating four points could result in a £200 penalty, with extra £200 penalties for continued missed deadlines at the threshold.
The first year is crucial for setting up a reliable routine.
Do not make MTD a quarterly panic
A straightforward way to prepare for Making Tax Digital is to shift from treating bookkeeping as a quarterly task.
Updating your books monthly makes the work before each deadline far easier.
By October, your bookkeeping should mainly involve reviewing and finalising records, not recreating them from scratch.
Regular bookkeeping can help you:
- Keep digital records current
- Spot missing transactions sooner
- Identify overdue invoices
- Reconcile accounts regularly
- Correct errors before deadlines
- Reduce the amount of catching up required
The upcoming MTD deadline is always approaching.
Staying up to date with your records means you’re already getting ready for it.
