Reporting a SEISS grant on your Self-Assessment return
You don’t need to repay a SEISS grant – it’s not a loan. However, SEISS grant awards are subject to Income Tax and Class 4 National Insurance contributions.
The SEISS grants are taxable in the tax year in which they are received. So, the first three SEISS grants are taxable in the 2020/21 tax year and they should be reported in full in your 2020/21 Self-Assessment tax return.
If you’re self-employed and your sole trader business receives a SEISS grant in the fourth or fifth rounds, they’re taxable in the 2021/22 tax year and should be reported on your 2021/22 Self-Assessment return.
To make it easier for self-employed people to enter money received from SEISS grants, HMRC will include a box on the 2020/21 and 2021/22 Self-Assessment tax return forms.
Track your income, expenses and file your tax return directly to HMRC today.
