Marriage Allowance vs Married Couple's Allowance 2026: Two Very Different Benefits
Marriage Allowance and Married Couple's Allowance sound similar but are entirely different tax reliefs with different eligibility rules. Marriage Allowance is available to most couples and saves up to GBP 252 per year, while Married Couple's Allowance applies only to those born before April 1935. This guide explains both.
Why These Two Allowances Are Frequently Confused
The names are similar, both involve couples, and both reduce a tax bill. But Marriage Allowance and Married Couple's Allowance are entirely separate reliefs with different mechanics, different eligibility requirements, and different values.
If you are confused about which applies to you, the simplest test is this: was either you or your spouse born before 6 April 1935? If yes, Married Couple's Allowance may apply. If no, only Marriage Allowance is available.
Marriage Allowance: How It Works in 2026/27
Marriage Allowance allows one partner in a married couple or civil partnership to transfer GBP 1,260 of their Personal Allowance to their partner. This reduces the receiving partner's tax liability by 20% of GBP 1,260, which equals GBP 252 per year.
Eligibility requires:
- You are married or in a civil partnership
- One partner's taxable income is below the Personal Allowance of GBP 12,570 (they have unused allowance to give away)
- The other partner pays Basic rate Income Tax (income between GBP 12,571 and GBP 50,270)
Higher or Additional rate taxpayers cannot receive the transfer. The saving is fixed at GBP 252 regardless of the transferring partner's exact income level, as long as eligibility is met.
You can backdate a claim by up to four previous tax years, which means couples who have been eligible since 2022/23 could potentially reclaim GBP 252 x 4 = GBP 1,008 as a lump sum, plus the current year's benefit.
Married Couple's Allowance: How It Works in 2026/27
Married Couple's Allowance is a legacy relief for older taxpayers. At least one partner must have been born before 6 April 1935 to qualify.
In 2026/27:
- Maximum Married Couple's Allowance: GBP 11,080
- Minimum Married Couple's Allowance: GBP 4,280
- Tax relief rate: 10%
- Maximum tax reduction: GBP 1,108 per year
The allowance is means-tested. It is allocated initially to the husband (or the higher earner in same-sex couples, by election). If the husband's income exceeds a certain threshold, the allowance is reduced until it reaches the minimum.
The relief mechanism is different from Marriage Allowance. Instead of transferring unused personal allowance, Married Couple's Allowance provides a direct 10% reduction in the tax bill of the qualifying partner.
