Marriage Allowance UK: Claim £252 Back - Your Guide to Tax Relief

What is Marriage Allowance UK?

Marriage Allowance is a UK government tax relief designed to help married couples and civil partners reduce their overall tax bill. It works by allowing one partner to transfer a percentage of their unused Personal Allowance to their spouse or civil partner. This can lead to a tax saving of up to £252 per tax year.

The Personal Allowance is the amount of income you can earn each tax year before you start paying income tax. For the 2024/25 tax year, the standard Personal Allowance is £12,570. If you earn less than this amount, you're not utilising your full Personal Allowance.

Marriage Allowance allows the lower earner (who earns less than their Personal Allowance) to transfer 10% of their Personal Allowance to their higher-earning spouse or civil partner, provided the higher earner is a basic rate taxpayer.

How does it work in practice?

Imagine one partner earns £10,000 a year, which is below the Personal Allowance of £12,570. They aren't using all of their tax-free allowance. Their spouse earns £30,000 a year and is a basic rate taxpayer. The lower earner can transfer £1,257 (10% of £12,570) of their unused Personal Allowance to their spouse.

This means the higher earner's taxable income is effectively reduced by £1,257. For a basic rate taxpayer (paying 20% tax), this results in a tax saving of £252 (£1,257 x 20%).

It's important to note that the Marriage Allowance can be backdated for up to four tax years. This means if you're eligible but haven't claimed, you could receive a significant rebate covering previous years, potentially adding up to over £1,000.

Who is eligible for Marriage Allowance?

To be eligible for Marriage Allowance, both you and your partner must meet specific criteria:

• You must be married or in a civil partnership. This allowance is not available to cohabiting couples or those in a common-law marriage. Unfortunately, if your spouse or civil partner has died since the claim began, you can still claim.
• One partner must have an income below the Personal Allowance. For the 2024/25 tax year, this means earning less than £12,570.
• The other partner must be a basic rate taxpayer. This means their income must be between £12,571 and £50,270 for the 2024/25 tax year. If your partner pays higher or additional rate tax, you won't be eligible.
• Both partners must have been born on or after 6 April 1935. Marriage Allowance replaced the Married Couple's Allowance, which applies if one partner was born before 6 April 1935. You cannot claim both.

What if my income changes?

Your eligibility can change from one tax year to the next if your or your partner's income changes significantly. For example, if the lower earner starts earning above the Personal Allowance, or the higher earner moves into the higher-rate tax bracket, you would no longer be eligible.

If your circumstances change, it's crucial to inform HMRC to avoid issues. You can cancel your Marriage Allowance claim online or by contacting HMRC directly.

How to claim Marriage Allowance UK

Claiming Marriage Allowance is a straightforward process and can be done online, by post, or by phone. It's usually the lower earner who makes the claim, as they are transferring a portion of their allowance.

Online through GOV.UK

This is often the quickest and easiest way to apply. You'll need:

1. Your National Insurance number.
2. Your partner's National Insurance number.
3. A valid UK passport or P60. You'll need these to prove your identity through the Government Gateway account setup process if you don't already have one.

Follow these steps:

• Go to the 'Apply for Marriage Allowance' page on GOV.UK.
• Click on 'Apply online'.
• You'll be asked to sign in to your Government Gateway account or create one if you don't have one.
• Once logged in, follow the on-screen instructions to provide your details and your partner's details.
• HMRC will review your application and confirm if you're eligible.

By phone

If you prefer to speak to someone or encounter issues with the online service, you can call HMRC's Income Tax helpline. Make sure you have your National Insurance number and your partner's to hand.

By post

While less common nowadays, you can also claim by post. You'll need to download and complete a form from the GOV.UK website and send it to HMRC.

What happens after you claim?

If your claim is successful:

• For the current tax year: The higher earner's tax code will be adjusted to reflect the transferred allowance, meaning they'll pay less tax going forward.
• For previous tax years (backdated claims): You will usually receive a refund cheque or a bank transfer for the overpaid tax. This can often be a substantial sum, particularly if you backdate for four years.

Important: Once you've claimed, you don't need to reapply each year, provided your circumstances remain the same. The allowance will continue automatically until you or your partner inform HMRC of a change in circumstances.

The financial benefits: How much can you save?

The potential savings from Marriage Allowance can be significant, especially when backdating claims for previous tax years. Here's a breakdown:

Current Tax Year Savings (2024/25)

• The lower earner transfers 10% of their Personal Allowance: £1,257.
• The higher earner's taxable income is reduced by £1,257.
• At the basic rate of tax (20%), this means a saving of £1,257 x 0.20 = £252.

This £252 will be reflected in the higher earner's payslip through an adjusted tax code, meaning they will take home more pay each month.

Backdated Claims

You can backdate your claim for up to four previous tax years. This means you could receive a lump sum payment. Let's look at the maximum potential backdate for a full four years:

Tax Year	Personal Allowance	Transferred Amount (10%)	Basic Rate (20%)	Max Saving per Year
2023/24	£12,570	£1,257	20%	£252
2022/23	£12,570	£1,257	20%	£252
2021/22	£12,570	£1,257	20%	£252
2020/21	£12,500	£1,250	20%	£250
Total Backdated Saving	-	-	-	£1,006

Combined with the current year's saving, a new claimant could potentially receive approximately £1,258 (£1,006 + £252) in tax relief. This comes as a welcome boost to household finances, particularly in the current economic climate.

Example Scenario

Sarah and Mark are married. Sarah works part-time and earns £9,000 a year. Mark works full-time and earns £35,000 a year.

• Sarah's income: £9,000 (below Personal Allowance of £12,570). She is the lower earner.
• Mark's income: £35,000 (between £12,571 and £50,270). He is a basic rate taxpayer.

Sarah can transfer £1,257 (10% of £12,570) of her unused Personal Allowance to Mark. Mark's taxable income reduces from £35,000 to £33,743. His tax bill will then be £1,257 x 20% = £252 lower. This saving will be automatically applied to his payslip each month, or he will receive a refund for any overpaid tax in the current year.

If they haven't claimed before and are eligible for the previous four years, they would also receive a lump sum of £1,006 for the backdated claims.

Common pitfalls and things to watch out for

While Marriage Allowance is a fantastic benefit, there are a few common misunderstandings and pitfalls to be aware of:

• Higher Rate Taxpayers: Crucially, if the higher earner is a higher or additional rate taxpayer, you are not eligible for Marriage Allowance. This is a common point of confusion. The allowance is specifically for basic-rate taxpayers.
• Income fluctuations: If either yours or your partner's income changes significantly, you might lose eligibility. For instance, if the lower earner's income rises above the Personal Allowance, or the higher earner moves into the higher-rate tax bracket, you must inform HMRC.
• Only one claim per couple: Only one partner needs to apply, usually the lower earner. Once transferred, the allowance applies to the higher earner.
• Death of a partner: If a partner dies after claiming Marriage Allowance, the surviving partner will continue to receive the allowance for that tax year. If the lower earner dies, the survivor can still claim the allowance for the part of the tax year prior to death.
• Not the same as Married Couple's Allowance: These are two different allowances. Married Couple's Allowance applies if at least one partner was born before 6 April 1935. You cannot claim both.
• Backdating limits: You can only backdate your claim for a maximum of four tax years, beyond which you lose the opportunity to reclaim past relief.
• Scams: Be wary of scam companies or individuals offering to claim Marriage Allowance on your behalf for a fee. The process is free and straightforward via GOV.UK. Third-party companies often charge a significant percentage of your refund, which is unnecessary.

How to cancel Marriage Allowance

If your circumstances change and you no longer wish to claim or are no longer eligible, it's important to cancel the allowance with HMRC. You can do this by:

• Logging into your Government Gateway account and managing your tax services.
• Calling HMRC's Income Tax helpline.

Failing to cancel could lead to an underpayment of tax for the higher earner, which HMRC may then seek to recover.

Marriage Allowance vs. Married Couple's Allowance

It's easy to confuse these two tax benefits, as their names are similar. However, they are distinct and have different eligibility criteria.

Feature	Marriage Allowance	Married Couple's Allowance
Eligibility	One partner earns below Personal Allowance, other is basic rate taxpayer. Both born AFTER 5 April 1935.	At least one partner born BEFORE 6 April 1935.
Who claims	Lower earner (transferor)	Higher earner (transferee)
Benefit	10% of Personal Allowance transferred to spouse, saving up to £252.	Tax reduction between £401.50 and £1,037.50, depending on age.
How it works	Reduces higher earner's taxable income.	Reduces tax bill directly (not Personal Allowance).
Claim method	Online via GOV.UK, phone, post	Usually claimed on Self Assessment, or by phone/post.
Backdating	Up to four previous tax years	Up to four previous tax years
Can you claim both?	No	No

If you believe you might be eligible for Married Couple's Allowance, you should check the specific criteria on the GOV.UK website or contact HMRC for advice. It is specifically for older married couples or civil partners.
