Marriage allowance

I was applied Marriage allowance and transfer 10% to my husband. My husband already received the letter and has been approved the marriage allowance. But when he want to summit the self assessment,the calculator form is not show have 10% marriage allowance, what need to do please.

I have the same issue. My tax coding clearly shows that 10% allowance is transferred from my wife, but the SA tax calculation does not seem to reflect the larger (110%) personal allowance in the calculation. I have rechecked my SA and all the input seems to be correct. Can someone advise please?

Hi halokittytoby Toby@0717,
Please make sure that your husband fulfills the criteria to receive your marriage allowance transfer, including not being a higher rate taxpayer.
You can read more here -
Marriage Allowance: How it works - GOV.UK .
Also, if you complete a Self Assessment tax return for yourself, please submit this first - if your husband submits his return before you do, the transfer may not show initially. If after ensuring the above your husband still experiences the same issue, please contact us by webchat or phone via:
Self Assessment: general enquiries and we can check the transfer.
​​​​​​​Thank you.

Hi,
If you are in receipt of the marriage allowance then you do not enter anything on the Self Assessment tax return. Once your tax return is processed our systems will pick up the marriage transfer and amend the tax return.
If this has not been updated then you will need to contact HMRC to review:
Self Assessment: general enquiries
Thank you
