Is Marriage Allowance different in Wales?

One partner must earn under £12,570 (Personal Allowance). The other must be a basic or higher rate taxpayer earning up to £50,270. Welsh taxpayers receive a C-prefixed tax code (C1383M) rather than the standard 1383M used in England and Northern Ireland.

Can Welsh couples backdate a Marriage Allowance claim?

Yes. Up to 4 previous tax years can be claimed, exactly as in England. Total backdated saving can be up to £1,008 for 4 years. Claims are made at gov.uk/apply-marriage-allowance.

Marriage Allowance for Welsh taxpayers — 2025-26

Marriage Allowance allows a lower-earning spouse or civil partner to transfer £1,260 of their Personal Allowance to their partner. In Wales, the tax saving uses Welsh Rates of Income Tax (WRIT), which are set by the Senedd (Welsh Parliament).

For 2025-26, the Senedd has matched England's income tax rates exactly — 20% basic, 40% higher, 45% additional. This means the Marriage Allowance saving for Welsh taxpayers is the same £252/year as for English taxpayers.

Welsh recipients of Marriage Allowance get a C-prefixed tax code — C1383M instead of 1383M. The eligibility ceiling in Wales is £50,270 (same as England), unlike Scotland where it is £43,662.

To claim, apply at gov.uk/apply-marriage-allowance. HMRC adjusts both partners' tax codes. Claims can be backdated for up to 4 tax years.
