HMRC self assessment: Common mistakes
Here’s a list of common mistakes made by users –
- Entering incorrect bank details
- Incorrect tax return numbers
- VAT errors
- PAYE details mistakes
Let us take a close look at each type of mistake and find ways to solve them.
1 Entered incorrect bank details
If you’ve provided the wrong bank account details for a tax refund, this is something you’ll want to rectify as quickly as possible to avoid delays or the payment going to the wrong account. The best way to handle this is usually by calling the relevant HMRC helpline. Be ready to provide the correct bank account number, sort code, and account holder name.
HMRC will then be able to update their records and ensure any future payments are sent to the correct place. They might also be able to trace a payment that has gone to the wrong account, although this can sometimes be a more complex process.
2 Entered incorrect tax return (self assessment) details
If you’ve made a mistake on your Self Assessment tax return, the process for correcting it depends on whether you filed online or by paper and how much time has passed since the filing deadline. If you filed online and it’s within 12 months of the filing deadline (usually 31st January for online returns), you can usually amend your return online through your HMRC online account.
If you filed by paper or if the 12-month window has passed, you’ll typically need to write to HMRC to explain the error and provide the correct information. You’ll need to include your UTR and the tax year the amendment relates to. HMRC will then review your amendment and update your tax calculation accordingly.
3 Incorrect PAYE details
If you believe your employer has submitted incorrect PAYE information to HMRC on your behalf (for example, incorrect earnings or tax deductions), your first step should be to speak to your employer. They are responsible for submitting this information and will need to make any necessary corrections through their payroll system.
If your employer is unable or unwilling to correct the error, you can then contact HMRC directly. Be prepared to provide details of the incorrect information and the correct figures. HMRC can then investigate the issue with your employer.
4 VAT errors
If you’ve made a mistake on your VAT return, the rules for correcting it depend on the value of the error and how you submitted your return. For errors below a certain threshold (currently £10,000 or 1% of your turnover, whichever is lower), you can usually correct them on your next VAT return.
For larger errors or if you need to correct a return outside of your normal accounting periods, you’ll likely need to notify HMRC separately, either online or by post, using form VAT652. The GOV.UK website provides detailed guidance on correcting VAT errors.
Steps to correct the mistake: Contact, correction, re-submission & more
1 Identify the type of mistake
The first step is to identify the type of the mistake made by the applicant. You may identify the mistake committed from the list provided above.
2 Contacting HMRC
After identifying the mistake, you may contact the HMRC and notify them about the mistake. You may know more about the correction procedure from the officials at HMRC. You may get in touch with them via phone, email or by post.

1 Identifying & reporting the error to HMRC
Once you’ve contacted HMRC and reported the error, what happens next? This will depend on the nature of the mistake and the method you used to report it. Depending upon the type of the mistake, you may be asked to submit relevant supporting documents, files or data.
2 Getting confirmation from HMRC
If you contacted HMRC by phone or online, you might receive immediate confirmation that your issue has been noted and is being looked into. If you wrote by post, it will take longer for them to acknowledge receipt. This is why sending by recorded delivery is a good idea – you’ll at least know they’ve received it.
3 Processing time
The time it takes for HMRC to process your correction can vary significantly. Simple errors might be rectified relatively quickly, while more complex issues could take several weeks or even months to resolve. Be patient, but don’t hesitate to follow up if you haven’t heard anything within a reasonable time-frame (e.g., a few weeks for phone/online queries, a month or more for postal submissions). When you follow up, have your reference numbers and details of your initial contact ready.
4 Updated documentation
Once the correction has been made, HMRC might send you updated documents, such as a revised tax calculation, a new tax code, or confirmation of a change in your records. Make sure you keep these documents safe for your records.
5 Pay penalties (if applicable)
In some cases, submitting incorrect information to HMRC can lead to penalties, especially if the error resulted in an underpayment of tax and was deemed to be careless or deliberate. However, if you proactively report an error and cooperate with HMRC to correct it, this can often mitigate or avoid penalties. It’s important to be honest and transparent in your communication with HMRC.
