Why you should consider the Marriage Allowance
Many married couples and civil partners could be missing out on valuable tax savings. The Marriage Allowance offers a simple way to reduce your household tax bill. If your circumstances are suitable, you should consider the Marriage Allowance as soon as possible. A straightforward claim could save you up to £252 during the 2026–27 tax year. Furthermore, backdating your claim could unlock even greater savings.
What is the Marriage Allowance?
The Marriage Allowance lets one spouse or civil partner transfer part of their Personal Allowance to the other. Specifically, the lower earner can transfer £1,260 of their unused allowance to their partner. The standard Personal Allowance for the 2026–27 tax year is £12,570. Therefore, the transferring partner’s allowance reduces to £11,310. In return, the receiving partner’s allowance increases to £13,830.
This transfer directly lowers the amount of Income Tax the higher-earning partner pays. As a result, the couple benefits overall even though one partner’s allowance decreases. For many households, this provides an easy and effective tax-saving opportunity. You do not need to change your working arrangements or income levels to benefit.
Who can claim?
To qualify, both partners must meet certain conditions. Firstly, you must be married or in a civil partnership. Secondly, the person transferring the allowance must have income below their Personal Allowance. Thirdly, the receiving partner must normally be a basic rate taxpayer. This generally means they have income between £12,571 and £50,270 during 2026–27.
Importantly, both partners must be basic rate taxpayers for the claim to succeed. If the higher earner pays tax at the higher or additional rate, the couple will not qualify. Therefore, you should review both partners’ income before making a claim.
Additionally, different limits apply for Scottish taxpayers. Scotland operates its own separate Income Tax bands. Consequently, the qualifying income thresholds differ slightly. Scottish couples should check the current Scottish rates to confirm their eligibility.
How the tax saving works in practice
When you consider the Marriage Allowance, it helps to understand the practical benefit. The receiving partner gains an extra £1,260 of tax-free income. At the basic rate of 20%, this produces a saving of £252 per year. Although this may seem modest, it adds up significantly over time.
Moreover, the overall effect is usually beneficial for the couple as a whole. The lower earner loses a portion of their Personal Allowance that they were not fully using. Meanwhile, the higher earner gains relief they can use immediately. Therefore, no money is lost in the process. The couple simply redistributes an unused tax benefit more effectively.
Backdating your claim for additional savings
It is also worth remembering that you can backdate your claim. Where eligibility existed in earlier years, HMRC allows couples to claim retrospectively. Currently, eligible couples can backdate a claim to 6 April 2022. As a result, this could produce a useful lump-sum repayment from HMRC.
Therefore, if you have been eligible for several years but never claimed, you should consider the Marriage Allowance backdating option. The combined savings across multiple years can be substantial. You can make the claim online through the HMRC website, and the process is straightforward.
What happens after you claim?
Once you make a successful claim, the allowance usually continues automatically in future tax years. You do not need to reapply each year. However, the allowance will stop if you cancel it or if a change in circumstances affects your eligibility.
Changes that could affect your claim include:
- Divorce or dissolution of the civil partnership
- Income changes — for example, the higher earner moving into a higher tax band
- Death of either partner
- The lower earner’s income exceeding the Personal Allowance
Consequently, you should review your eligibility regularly. Couples whose income levels have changed recently should check whether they still qualify. Equally, those who previously did not qualify may now find they are eligible.
Common reasons people miss out
Despite its simplicity, many eligible couples overlook this relief. Some assume it only applies to retired couples or single-income households. Others are unaware it exists at all. In reality, any qualifying couple can benefit. For instance, couples where one partner works part-time often qualify.
Additionally, some people confuse the Marriage Allowance with the older Married Couple’s Allowance. These are separate reliefs with different eligibility rules. The Married Couple’s Allowance applies only where one partner was born before 6 April 1935. In contrast, the Marriage Allowance is available to all qualifying couples regardless of age. Therefore, younger couples should also consider the Marriage Allowance when reviewing their tax position.
