How to Check If My Tax Return Is Filed with HMRC
That uneasy feeling usually arrives after a long day on the road, on site, or catching up with paperwork: did the Self Assessment return actually go through? If you need to check if my tax return is filed, do not rely on whether you remember pressing ‘submit’. HMRC provides clear signs that a return has been received, and checking early gives you time to fix any problem before it turns into a penalty or a chasing letter.
For sole traders, landlords, CIS subcontractors and company directors, this is one of those small admin checks that can save a lot of unnecessary stress. A submitted return is only part of the job. You also need to know what tax is due, when it must be paid and whether HMRC has processed the figures as expected.
How to check if my tax return is filed online
The quickest way to check is through your HMRC online account or the HMRC app. Sign in using the Government Gateway details you used for Self Assessment, then select Self Assessment and look for your submitted returns or tax return history.
If the return has been filed successfully, you should normally be able to see the relevant tax year marked as submitted. You may also see a submission receipt, confirmation reference, the date it was received and a calculation showing the tax due. Save or download this confirmation for your records. It is useful evidence if there is ever a query over the filing date.
If an accountant submitted the return on your behalf, ask for a copy of the completed return and the electronic submission confirmation. A professional accountant should be able to tell you when it was filed, what income and expenses were included, the tax calculation and the payment dates to work to. Do not assume that sending your records to an accountant is the same as authorising and submitting a completed return.
A paper return is different. HMRC does not provide the same immediate online proof of receipt, and post can take time to process. If you posted a return, check whether you used tracked delivery and retain the proof of posting. You can also contact HMRC to ask whether it has been logged, though this may not be visible straight away.
The signs your return was submitted properly
A successful online submission generally leaves more than one trace. Your online account should show the return for the correct tax year, and the tax calculation should match the information you approved. You may also receive an acknowledgement by email if your account settings allow it, but the status in your HMRC account is the more reliable check.
Be careful with the wording on screen. ‘Saved’, ‘in progress’ or ‘ready to send’ does not mean filed. Equally, a return can be received but still need amendment later if you spot an error. The key is that it shows as submitted for the right year.
For example, if you are filing your 2025-26 return, make sure you are not looking at confirmation for 2024-25. It sounds obvious, but this catches people out when they have several years of Self Assessment history in the account.
Why a filed return may not look right
Sometimes HMRC has received the return but the account still raises questions. The most common issue is confusing the filing position with the payment position. Submitting a return before the 31 January deadline does not settle the tax bill. If you owe tax, the balancing payment is normally due by 31 January following the end of the tax year. You may also have payments on account due on 31 January and 31 July.
A return can also appear to show an unexpected amount due because of earlier underpayments, payments on account, late-payment interest or a coding adjustment. CIS subcontractors should check that all tax deductions shown on their monthly statements have been included. Missing CIS deductions can make the bill appear far higher than it should be, or reduce the refund due.
Landlords should check that rental income, allowable costs and any share of jointly owned property have been reported correctly. Limited company directors need to separate their personal Self Assessment position from the company’s Corporation Tax return. One being filed does not confirm that the other has been dealt with.
If your account says a return is overdue even though you submitted one, do not ignore it. It could be a processing delay, a return filed for the wrong period, a technical submission issue or an HMRC record that still needs correcting. Keep your submission reference and contact HMRC or your accountant promptly.
What to do if you cannot see a submitted return
First, make sure you are signed in to the correct Government Gateway account. It is not unusual for someone to have more than one login, particularly where a business was previously managed by a family member, bookkeeper or former accountant.
Next, check that you are viewing Self Assessment rather than PAYE. Employees who have tax taken through wages can still need Self Assessment if they have untaxed income, rental income, substantial dividends or self-employed earnings. The two services display information differently.
If you filed very recently, allow a little time for HMRC’s systems to update. However, do not leave the matter for weeks if a deadline is close. Find the confirmation email, submission receipt or accountant’s acknowledgement. If there is no evidence of submission, treat the return as unfiled until you have confirmed otherwise.
Avoid filing a duplicate return simply because you cannot immediately find the status. A second submission may replace the first or create extra work to untangle the position. Check the facts first, then take advice if anything does not add up.
Check more than the submission date
Once you have confirmed your return is filed, take five minutes to look at the wider position. Check the tax calculation, the payment deadline and whether payments on account apply. If you have a refund due, confirm the bank details held by HMRC are correct and that the repayment claim has been made where required.
This is particularly worthwhile for tradespeople and drivers with changing income. A busy year, a new contract, a vehicle replacement or higher fuel and materials costs can all affect the final tax figure. The return may be filed correctly but still include missed expenses or an incorrect income entry. Amendments are often possible after submission, but it is better to deal with errors while records are fresh.
Keep the return, calculation, supporting records and proof of submission together. For most Self Assessment records, you should retain evidence for at least five years after the 31 January submission deadline. That includes invoices, bank records, mileage information, CIS statements, rental paperwork and expense receipts relevant to the return.
When it makes sense to ask for help
If you have missed the filing deadline, cannot locate proof of submission, have received an HMRC penalty notice, or your calculation does not reflect your records, getting help early is usually cheaper than trying to repair things after several letters have arrived. The same applies if you are unsure about allowable expenses, CIS deductions, rental income, dividends or payments on account.
