  • Marriage Allowance - forgot to fill in details in SA for 20/21

    Hi there, my other half is self-employed and on some occasions dependent on income (most recently for the tax year 21/22) has passed on personal tax allowance to me via the marriage allowance. We have realised that they didn't complete the relevant part of the self-assessment form for 20/21 for marriage allowance. As a result, I didn't get the marriage allowance and a subsequent rebate. Is there a way for us to rectify this retrospectively either online via the Self Assessment platform or over the telephone?
