Self-employed individuals (including partnerships) who have overclaimed the Self Employed Income Support Scheme (SEISS) must pay back the overpayment to HMRC. The rules for repaying HMRC state that you must tell HMRC if you were not eligible to have claimed the grant. 

For example:

• for the first or second grant, your business was not adversely affected
• for the third or fourth 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 since 5 April 2018

You must also tell HMRC if you:

• received more than we said you were entitled to
• amended your tax return on or after 3 March 2021 in a way which means you’re entitled to a lower grant than you received

If you have overclaimed you must tell HRMC within 90 days of receiving the grant or face additional penalties. If the amount in question is £100 or less then there is no requirement to notify HMRC or pay back any grant received. 

All qualifying self-employed businesses can continue to claim SEISS grants until 30 September 2021, if they continue to be adversely affected by the coronavirus pandemic. A fourth grant covers the period from 1 February 2021 to 30 April 2021 and a fifth and final grant will cover the period from May onwards.

The fourth grant will provide support covering 80% of average trading profits, up to a maximum of £7,500 for those who meet the eligibility requirements. The fifth and final grant will see those whose turnover has fallen by 30% or more continuing to receive the full 80% grant whilst those whose turnover has fallen by less than 30% will receive a 30% grant.
