Marriage Allowance unable to transfer on my current self assessment return

I have tried to file my self assessment online today and transfer 10% personal allowance to my spouse. The system show : Error: As you have already made three attempts to match your Recipient details, you cannot select to transfer your Marriage allowance in this return. so I submitted the apply for marriage allowance via online account separately. My question is as the transfer of 10 % allowance cannot reflected on my return now, should I still submit the self assessment at stage, because after I transferred out 1,260 allowance, I might need to pay a little bit of tax. Please advise. Thank you

Hi

Once the transfer request is processed, your tax return calculation would be amended to include the transfer. It won't show until after the ta return has been submitted.

Thank you
