The Covid-19 support grants (CJRS, SEISS and Eat Out to Help Out) are taxable and should be declared on your business' tax return. For corporation tax (CT) you must report amounts received in the accounting period covered by the return, not grants claimed for the period and paid in a later period.

Self-employed individuals will be able to apply for the fourth SEISS grant from late April if they submitted their tax return for 2019-20 by midnight on 2 March 2021 (it was due by 31 January 2021).

As a self-employed individual you may have been able to claim up to three grants under the self-employed income support scheme (SEISS) since the start of the pandemic.
