Match the HMRC activity and software confirmation to the correct business, tax year and update period. Uploading receipts or finishing bookkeeping is not proof of submission. If the evidence is missing or contradictory, ask the accountant to check before anyone sends a duplicate.
Ask for evidence with four matching details
The confirmation should identify the business or property source, tax year, update period and submission outcome. Keep a reference or receipt where available. If you have a trade and property, proof of one does not establish that both were sent.
Check HMRC activity and software results
HMRC says recent activity in the online account shows a sent update. Compatible software should also show the result. If an accountant files, ask for that confirmation rather than relying only on a progress message.
Understand the period shown
A standard second 2026/27 update covers 6 April to 5 October 2026. A confirmation for a different period or business is not proof of that obligation. Match cumulative coverage, especially after a handover.
If the evidence does not agree
Ask the accountant to check the filing software and HMRC account. A failed submission, a delayed display and an incomplete records task need different responses. Do not send a duplicate simply because a screen has not refreshed.
Retain the figures reviewed, any correction queries and final confirmation together. If something failed, record the error, who will resolve it and when the result will be checked. These records make a later accountant handover easier too.
Check your own HMRC activity
Sign in through the official personal tax account entry point using your own details. HMRC’s guidance says recent activity shows “You sent a quarterly update”. Match the relevant business and period with the software confirmation.
If the software says submitted but the account does not agree, give the accountant both pieces of evidence and ask it to verify the outcome. Do not turn an uncertain display into a second filing. Agree when you will receive the checked result.
Match the receipt to the actual obligation
Illustrative example.
A taxpayer runs a trade and also has a property business. A confirmation for the trade’s first update does not show that the property business’s second update was filed. A green “complete” badge without the business and period is not enough to resolve that question.
Ask the accountant to match each obligation to its submission result and HMRC activity. Keep the date, business, tax year, period and available confirmation together. If one source is missing, agree who investigates it before attempting another submission.
| Check | Practical action |
|---|---|
| Business | Match the correct trade or property business. |
| Period | Check the tax year and cumulative coverage dates. |
| Outcome | Check actual submission evidence rather than document-upload status. |
Does a successful bank feed prove submission?
No. Imported transactions are an input to record-keeping, not filing evidence.
Should I submit again if the dashboard is slow?
Check the software outcome and HMRC activity first. Resolve the uncertainty before attempting another filing.
