Tell HMRC and pay back a Self-Employment Income Support Scheme grant

Find out what to do if you need to pay back some or all of a SEISS grant.

You must tell HMRC if, when you made the claim, you were not eligible for the grant. For example:

  • for the first or second grant, your business was not adversely affected
  • for the third, fourth or fifth grant, your business had not been impacted by reduced activity, capacity or demand or inability to trade in the relevant periods
  • you did not intend to continue to trade
  • you’ve incorporated your business

You must also tell us if you:

  • received more than we said you were entitled to
  • amended any of your tax returns on or after 3 March 2021 in a way which means you’re no longer eligible or are entitled to a lower fourth or fifth grant than you received
  • made a mistake reporting your turnover in your claim for the fifth grant which means you are entitled to a lower grant than you received
  • have received a letter or email from HMRC that says you need to pay back some or all of a grant

When you must tell HMRC

In most cases, if you’re not eligible and have to pay the grant back, you must tell us within 90 days of receiving the grant.

For the fourth and fifth grants the rules for when to tell us are different if amending your return affects your eligibility or grant amount. 

If your return has been amended

You must tell us if there is an amendment to any of your tax returns on or after 3 March 2021 which either:

  • lowers the amount of fourth or fifth grant you’re eligible for 
  • causes you to no longer be eligible for the fourth or fifth grant 

If your return has been amended before claiming your grant, you must tell us within 90 days of receiving your grant.

If your return has been amended after receiving your grant, you must tell us within 90 days of making the amendment.

If you do not tell us, we’ll write to you to recover the grant and you may also have to pay a penalty. Find more information on how we will recover your overpaid grant.

You do not have to tell us if the grant amount:

  • you are eligible for has lowered by £100 or less
  • was £100 or less

If you are not sure, you should still tell us about the amendment using the online form. 

If you made a mistake when reporting your turnover

You need to tell us if you:

  • made a mistake reporting your turnover in your claim which means you are entitled to a lower grant than you received
  • later realise you should have reported a different turnover figure in your claim which means you are entitled to a lower grant than you received

Voluntary repayments

You can also tell us if you want to voluntarily pay back some or all of the grant you received. You can do this at any time.
