Marriage Allowance Deadline: Act Now to Save Up to £252 on Your Tax Bill
As the tax year draws to a close on April 5, 2026, financial experts are issuing an urgent call to action for married couples across the UK. Time is running out to claim the Marriage Allowance, a government scheme that could save eligible couples up to £252 per year, with potential backdated claims exceeding £1,000. Failure to act before the deadline could mean inadvertently gifting hundreds of pounds to HM Revenue and Customs.
What Is the Marriage Allowance and How Does It Work?
The Marriage Allowance allows a lower-earning spouse, who earns below the personal allowance threshold of £12,579, to transfer £1,260 of their unused personal allowance to their partner. This transfer is only available if the recipient is a basic-rate taxpayer. In simple terms, this means that if one partner earns less than the personal allowance and the other pays tax, the couple can reduce their overall tax bill through a straightforward process.
Despite its simplicity, thousands of eligible couples miss out on this benefit each year, often due to a lack of awareness or misconceptions about the complexity of the application. Samuel Mather-Holgate, managing director of Mather and Murray Financial, emphasises that this is one of the most overlooked tax opportunities available.
Expert Advice: Don't Miss Out on Easy Savings
Samuel Mather-Holgate has highlighted the urgency of the situation, stating, "This is one of the easiest tax wins available right now, especially this close to the tax year end." He warns couples not to accidentally gift HMRC £252 by missing the deadline. The application process is quick and straightforward, typically taking just minutes to complete online via the HMRC website.
He adds, "If you've forgotten to do it, you can backdate it up to four years. That means this simple step could be worth over £1,000 in total. It's the tax equivalent of finding money at the back of the sofa. It's a five-minute form for what could be a four-figure benefit." With the ongoing cost of living crisis putting pressure on household finances, this allowance offers a practical way to boost income without altering spending habits.
Key Deadlines and Eligibility Criteria
Timing is crucial for maximising savings. While applications can be made at any time, couples aiming to claim for the current tax year must act before the April 5, 2026, cut-off. Paper applications are possible, but Samuel cautions that they risk missing the deadline due to slower processing times, potentially resulting in the loss of this year's saving.
To qualify for the full benefit, couples must meet specific criteria:
- Be married or in a civil partnership.
- The higher earner must remain within the basic-rate tax band.
- The lower earner must have an income below the personal allowance threshold.
This scheme is designed to provide financial relief to couples where one partner earns significantly less, making it a valuable tool for household budgeting. As the deadline approaches, experts urge all eligible couples to review their situation and apply promptly to secure these tax savings.
