  • Trying to submit Apr '21 to '22: "You cannot use this service."

    Hello, any help on the below appreciated please. I want to submit my self-assessment tax return for financial year 6 Apr 2021 to 5 April 2022, during which I was self-employed. Problem: I get the error "You cannot use this service." in the box next to Apr 21 to Apr 22 at So I can't submit my return. Details: The previous year (20-21) I was employed and the system tells me I submitted the right amount of tax. In order to access 21-22 I click 'Choose which year to view' at the top. For 21-22 I get this error saying I can't use this service. I registered as self-employed in August 2022, was this too late? Even though the deadline for the return is 31 Jan 2023? Any guidance appreciated. Thanks,
