How do I edit a submitted VAT return?
Once a return has been submitted through MTDsorted, you cannot make any changes to it.
As per the HMRC guidance for correcting errors in your VAT return, the next steps are to see if you need to report the issue to HMRC.
You should always keep a record of the details about the error, this should include the date it was discovered, how it happened and the amount of VAT involved.
When do you report errors to HMRC?
You can correct errors for VAT returns in the past 4 years, if the net value of the error is either:
- £10,000 or less
- between £10,000 and £50,000 but less than 1% of the total value of your sales.
You must tell HMRC separately for net errors that are:
- over £50,000
- over £10,000 if they exceed 1% of the total value of sales
- deliberate errors
How do you calculate the net value of errors?
To work out the net value of errors:
- Add up the additional tax due to HMRC
- Subtract the tax you're due
Note: You should not include any deliberate errors in this calculation.
How do you correct the VAT error?
If it’s not a reportable mistake, you can complete your next period VAT return to take into account any additional tax that you’re due to pay to HMRC, or subtract any that you’re reclaiming.
You should add the net value to box 1 for tax due to HMRC, or to box 4 for tax due back to you.
How do I report to HMRC?
If you must report the error to HMRC, you can either:
- complete the online report form
