Frequently asked questions

Is this an official HMRC or UK government service?
No. We are a private, independent document-assistance service. We are not HMRC and we are not affiliated with HMRC or the UK government.
Can I apply for free myself?
Yes. HMRC does not charge for Marriage Allowance — you can apply yourself for free directly with HMRC. Our £29 fee pays for the form preparation and postal submission, including backdated years in one go.
When and how do I receive my money?
HMRC pays any refund directly to you — usually by bank transfer or cheque. We never receive your refund. Processing typically takes several weeks after HMRC receives the form.
Can I backdate a claim?
Yes — Marriage Allowance can be backdated up to 4 tax years, but only by post on the HMRC MATCF form. The online HMRC service only handles the current tax year.
What does your service cost?
A one-off fee of £29, paid when you submit your details. HMRC's own service is free of charge.
