HMRC starts to assess grant overpayments

The fourth and fifth SEISS grants were calculated based on tax return information HMRC held on 2 March 2021, including the 2019/20 tax returns where these have been filed, along with any amendments made prior to that date. However, where amendments were made after this date it is possible that the entitlement to those grants would have reduced. For example, where the tax return was originally filed using estimated figures that were later corrected and the true figures were better than anticipated.

Amendments can be made by the individual taxpayer, directly by HMRC, or as the result of an enquiry. If the entitlement to the fourth and fifth grants was reduced by more than £100 as a result of the amendment, the taxpayer should expect a letter from HMRC very soon. This will contain an assessment of the amount that needs to be repaid, along with a breakdown of how that amount has been calculated. The letter will have a reference number and needs to be used to make the payment. The payment should not be made via the self-assessment account, and instead the instructions here should be followed. If payment is not made within 30 days, a 5% penalty will be applied unless a time to pay arrangement is set up before that deadline. It is possible to appeal in writing within 30 days of the date on the letter.
