Hi Stephanie Greathead
If you applied for Marriage Allowance through an agent or third party, this may account for the delay in receiving your rebate - please contact this agent or third party for progress on receiving your refund.
If you applied for Marriage Allowance through HMRC directly, and your refund is not showing as claimable on your Personal Tax Account, please contact us by webchat or phone via
Income Tax: general enquiries to allow us to review the progress of your claim.
Thank you
