If you're Self-Employed, you must make your claim for the third SEISS grant by 29th January.
The scheme has been extended. If you were not eligible for the first and second grant based on the information in your Self Assessment tax returns, you will not be eligible for the third.
To make a claim for the third grant your business must have had a new or continuing impact from coronavirus between 1 November 2020 and 29 January 2021, which you reasonably believe will have a significant reduction in your profits.
The third taxable grant is worth 80% of your average monthly trading profits, paid out in a single instalment covering 3 months’ worth of profits, and capped at £7,500 in total.
