What Happens if HMRC Make a Mistake

No one is perfect, and that includes the team at HMRC. In fact, it’s inevitable that mistakes will be made from time to time. The important thing is how you deal with those mistakes when they happen. 

In this blog post, we’ll take a look at what happens if HMRC makes a mistake on your tax return. We’ll also discuss your options for rectifying the situation. 

So, if you’re feeling worried about your taxes this year, read on!

Will HMRC Make a Mistake?


The short answer is yes, from time to time HMRC do make mistakes. In most cases, these mistakes are relatively minor and can easily be rectified by the taxpayer. However, there are occasional cases where more serious errors are made.

The mistakes made by HMRC can be broadly split into two categories: errors in the tax calculation, and errors in the administration of the tax return.

Errors in Tax Calculation

As the name suggests, these are mistakes that relate to the actual calculation of your tax bill. This could be something as simple as an incorrect figure being entered into the system, or a more complex error such as incorrectly applying a tax relief.

Errors in Administration of Tax Return

These are errors made by HMRC in the administration of your tax return, rather than in the calculation of your tax bill. This could include errors such as failing to process a paper tax return on time, or incorrectly recording information that you have provided.

What can I do if HMRC makes a Mistake on my Tax Return?


If you spot an error on your tax return, the first thing you should do is contact HMRC to let them know. You can do this by phone, post or online.

Once you have notified HMRC of the error, they will investigate and let you know what needs to be done to rectify the situation. In most cases, this will simply involve amending your tax return. However, if the error is more serious, you may need to provide additional information or documents.

If you disagree with HMRC’s findings, you have the right to appeal their decision. 

How to Dispute an HMRC Decision?


If you think that HMRC have made a mistake, you have the right to appeal their decision. You can do this by writing to HMRC and explaining why you believe their decision is incorrect.

If you’re not satisfied with HMRC’s response, you can escalate your appeal to the Tax Tribunal. The Tax Tribunal is an independent body that will review your case and make a final decision.

What if I don't Spot the Mistake?


If you don’t spot the mistake on your tax return, HMRC will eventually realise their error and send you a notice to let you know. This notice will include details of the mistake and how much extra tax you owe as a result.

If you’re unable to pay the additional tax bill, you should contact HMRC immediately to discuss your options. In some cases, HMRC may be willing to agree to a payment plan or offer other financial assistance.

What if I think HMRC have Made a Mistake, but I'm not Sure?


If you’re not sure whether or not HMRC have made a mistake, the best thing to do is get in touch with them and ask for clarification. HMRC have a dedicated team of advisors who will be able to help you understand their decision and why it has been made.

Consequences of an HMRC Mistake


If HMRC makes a mistake on your tax return, the consequences will depend on the severity of the error. In most cases, the mistake will simply result in you having to amend your tax return. However, if the error is more serious, you may end up owing additional tax.

If you don’t spot the mistake and HMRC eventually realise their error, you will be sent a notice telling you how much extra tax you owe. If you’re unable to pay the additional tax bill, you should contact HMRC immediately to discuss your options.
