Marriage Allowance not showing on husband's SA tax calculation

The marriage allowance is not showing on client's husband's self assessment tax calculation before submitting it was applied for successfully, it is showing his details on her return and has reduced her personal allowance accordingly. Can anyone help please? it was applied for on the 14th and an email was received to say was successful. Many thanks in advance

Hi Michael,
While the transfer from your client's record may have been successful, if your client's husband is a higher rate taxpayer, he would not be entitled to the transfer of allowances, and it would automatically be omitted from his own calculation. If neither are higher rate taxpayers, you may wish to try resubmitting your client's husband's return, as the transfer may not have had time to map over succesfully. If doing so does not update the calcualtion with the transfer, contact us by webchat or phone via Self Assessment: general enquiries, and we can confirm what is preventing the transfer.
Thank you.
