Correcting a return or accounts you have filed

How to put right a Company Tax Return or accounts that have already gone to HMRC or Companies House.

If you filed with us

Sign in and open your returns page. Next to the return or accounts you want to correct, press one of these:

  • Correct this return if something was wrong
  • Correct these accounts if something was wrong

We fill in the form from what we sent. Check every section, change what was wrong, then send it.

If you filed somewhere else

Start with the company number, as for any filing, and pick the dates of the filing you want to correct. If they aren't offered, press the link below: Choose custom dates

For a tax return, press: Correct a tax return HMRC already has for these dates

For accounts, press: Correct the accounts at Companies House

Then fill in the form with the right figures and send it.

What happens to the first filing

HMRC receives an amended return that says it changes the earlier one.

Corrected accounts say they replace the originals. A correction does not remove the first set from the public record.

If we can't correct it from here

HMRC only accepts an amended return for a limited time, and a few filings can't be corrected here. If that applies to yours, the form says so before anything is sent. Companies House also accepts corrected accounts on paper.

May we use analytics, and record your visit, to see where our form is hard to use? Analytics counts pages and notes clicks (including repeated clicks and clicks that do nothing), where people click, errors and page speed, never what you type. In a recording, our own words, such as headings, questions and hints, can show; what you type, and the company and tax details we show you, are hidden, and any other text is hidden unless we have marked it as our own. Your Companies House authentication code and Government Gateway login are never recorded. It is optional and does not change the service you get.
