Married Couple's Allowance

HM Revenue & Customs

Description

A distinct, much older allowance from Marriage Allowance, this reduces the tax bill for married couples or civil partners by between £436 and £1,127 a year (2026/27), depending on income. It's only available where at least one partner was born before 6 April 1935 — an increasingly narrow, very elderly group of claimants (at least one partner must now be 91 or over) — so most couples should look at Marriage Allowance instead.

Some of the organisations we may connect you with pay us a referral fee if you use their service. This never affects which listings you see in the directory. No live partner is confirmed yet for this listing.
