This guidance has been updated with information about the fourth SEISS grant. The online service to claim the fourth grant will be available from late April 2021. If you are eligible based on your tax returns, HMRC will contact you in mid-April to give you a date that you can make your claim from. It will be given to you either by email, letter or within the online service. You must make your claim on or before 1 June 2021.
How HMRC works out trading profits and non-trading income for the SEISS
HMRC look at your trading profits and non-trading income on your Self-Assessment tax returns to check if you meet the eligibility criteria for the fourth grant. They also use your average trading profits to work out how much grant you will get.
If you need help in claiming the fourth SEISS grant please contact MJB Avanti (08000) 388 799. We have access to accurate calculators to work out your likely claim amount.
