HMRC will work out your average trading profit by adding together your total trading profits or losses from all self-employments and partnerships for the three tax years, then we will divide by three. 

The Self-employment Income Support Scheme grant will be 80% of your average monthly trading profits, paid out in a single instalment covering three months, and capped at £7,500 altogether. HMRC advises payments will be made six working days from making the claim. The online service will tell you how we’ve worked the grant out. 

Please follow this link to see how HMRC will work out your average trading profits including if you have not traded for all three years.
