What is the Marriage Allowance?

HMRC has come up with a marriage allowance, which is a tax allowance allowing you to transfer part of your personal allowance to your civil partner or spouse. At present, it is possible to transfer £1,260 of personal allowance in case you earn below the personal allowance threshold.

This benefit favours couples in which one of them is earning lower than the personal allowance (£12,570 in the 2025/26 tax year) and the other partner is a basic rate taxpayer. The transferring partner is giving up a portion of their unused personal allowance, which can be utilised by the receiving partner to minimise their tax payment.

Example:

If one spouse earns £9,000 in a year and the other earns £30,000, they are eligible to claim the Marriage Allowance. The lower earner can transfer £1,260 of their Personal Allowance. It reduces their spouse’s tax bill by £252. The £252 is a tax credit which is calculated as 20% of the transferred amount. This can be a simple saving as long as both partners meet the eligibility conditions.

Eligibility Requirements for the Marriage Allowance

You can apply for the Marriage Allowance at any point during the tax year if you and your spouse meet the eligibility rules. HMRC can adjust your tax codes and reduce your tax bills as soon as you apply.

To qualify for the marriage allowance:

• You must be married or in a civil partnership.
• The income of a lower-earning partner must be below the Personal Allowance, which is currently  £12,570. 
• The higher-earning partner must be a basic rate taxpayer.
• Neither partner can be a higher-rate or additional-rate taxpayer.
• If both earn above £12,570, then there is no unused allowance to transfer, and
• Even if one partner has no income, they can still transfer part of their allowance to the other partner.

The Reasons to Cancel Your Marriage Tax Allowance

Marriage Allowance is such a nice benefit, though it is not a lifetime freebie. You should know what the key reasons are and why you may have to withdraw Marriage Allowance. 

• Change in Circumstances

Life does not stand still, and so are your financial situations. Maybe you have taken up a new job, got a promotion or you have started earning a bigger salary that makes you cross the personal allowance limit. Marriage allowance could no longer be useful when the income of the partner who earns less is significantly raised.

• Separation or Divorce

This is possibly the major reason why individuals should be aware of how to cancel marriage allowance. The tax benefits that you were sharing will end up with the end of relationships. The transfer of tax allowance of your wife or husband after a separation would lead to financial problems and could even make you cost heavily.

• Changes in Income

When the recipient partner turns out to be a higher rate taxpayer (earning above £50,270), he/she is no longer entitled to receive marriage allowance. Likewise, in case the income of the transferring partner increases beyond the personal allowance, then there is nothing to transfer. It becomes necessary to cancel marriage tax allowance.

What Is 1131N Tax Code?

On receiving marriage allowance, the tax code is amended to accommodate the new allowance. When you receive the transferred allowance, you are likely to receive 1131N tax code.

The suffix N means that you are receiving the marriage allowance benefit. The allowance will be transferred by your partner whose tax code will have an M suffix. Knowledge of these codes will let you know whether your marriage allowance is valid or not and when it has been cancelled successfully.

On cancellation, your tax code normally goes back to the standard code (which is normally 1257L with reference to the 2024/25 tax year), but again depending on your circumstances.

What is the Married Couple’s Allowance?

Married Couple’s Allowance is a tax benefit for married couples or those in a civil partnership where one partner was born before April 6, 1935. It reduces the amount of tax the couple has to pay and is based on the highest earner’s income.

Marriage Allowance, on the other hand, is a tax benefit for couples where one partner earns less than their personal allowance and the other partner is a basic rate taxpayer. It allows couples to transfer a portion of their personal allowance to their partner, reducing their overall tax bill. The two benefits are different, but both can help married couples save money on their taxes.

Paying your tax bills on time and accurately is a daunting and time-consuming exercise. AccountingFirms can help you manage your taxes and pay your taxes on time with the help of professional accountants.

When to Cancel Marriage Allowance?

Marriage Allowance isn’t a permanent benefit. Once you claim it, it renews automatically every year. If your circumstances change, you may need to cancel it.

Change in income levels

If the income of either partner changes, you may no longer be eligible for the Marriage Allowance. This means if the lower-earning partner’s total taxable income goes above £12,570, you must cancel the allowance. Similarly,  if the higher-earning partner becomes a higher-rate taxpayer, you must cancel the allowance. 

Divorce or Permanent Separation

Only married couples or civil partners are eligible for the Marriage Allowance. This means you must cancel it if you get a divorce or permanent separation. You can’t reapply unless you remarry or enter a new civil partnership.

If your partner dies

If a spouse or civil partner dies, the Marriage Allowance will end in the tax year of the death of the partner. The surviving partner may still receive benefits for that year.

The surviving spouse will need to notify HMRC about the death, which is usually handled when registering the death certificate. They should check if they’re owed a refund for part of the year.

Mistaken application

A person can apply by mistake, not realising they don’t qualify. You will need to cancel the allowance to avoid unexpected tax bills later.

How to Cancel Your Marriage Tax Allowance? Step by Step Process

Once you have decided to cancel the marriage tax allowance, doing so step-by-step will help you avoid tax complications. Follow the below-mentioned process to keep your tax record accurate and updated.

Step 1: Eligibility to Cancel

Before you go through the process of cancellation, make sure you really need to cancel. Evaluate the incomes and circumstances of both partners. There is no need to cancel the allowance in case you are still eligible and receiving the allowance.

Check your recent payslips or P60 to know your tax status. Check the suffix of tax codes, if your tax code has the M or N suffix, then you are still eligible and the allowance is active.

Step 2: Contact HMRC

Cancellation is the most straightforward option, which can be done by the personal tax account on GOV.UK. You will be required to create an account in case you do not have one.

Instead, you can use the Income Tax helpline of HMRC at 0300 200 3300. The lines are operating between Monday and Friday, 8am to 6pm. When calling, have your National Insurance number with you.

You may address HM Revenue and Customs at: Pay As You Earn and Self Assessment, HM Revenue and Customs, BX9 1AS.

Step 3: Finalise the Process of Cancellation

When you are using your online account, go to the section of marriage allowance and choose the option of cancellation. You will be required to give a reason why you want to cancel, e.g. change in circumstances or separation.

In case of calling, discuss your case with the HMRC advisor. They will guide you at every step and update your record. Record the date and time when you have called and request a reference number.

In writing, both partners should state their details and National Insurance numbers and the reason why you are cancelling.

Step 4: Verify New Tax Code

When the cancellation is made, the HMRC will send new tax codes to the two partners. This normally takes 8 weeks. Check your payslips and make sure that the new code is activated.

HMRC will notify your employer, hence you do not have to do this yourself. However, when you see that you are still using the old code two months later, call HMRC once more.

What Happens When You Cancel Your Marriage Allowance?

When you cancel your Marriage Allowance, your tax code will be adjusted, and you’ll stop receiving the benefit. This means that you’ll pay more tax than you would have if you had continued to receive Marriage Allowance.

You’ll also need to inform your partner that you’ve cancelled the benefit, as their tax code will also be adjusted. If you’re unsure whether to cancel your marriage allowance, you should speak to a tax professional who can advise you on your individual circumstances.

If You Have Forgotten to Cancel the Marriage Allowance, Then?

In case you forgot to cancel your marriage allowance at the right time, there is no need to panic. HMRC realises that things evolve and individuals forget to inform them. Nevertheless, by still claiming the marriage allowance when you are not entitled to it. You risk having paid less than you should have paid in taxes. HMRC can revise your tax code from back date to collect the outstanding amount, which is usually spreading it over your subsequent earnings.

Call HMRC immediately upon becoming aware of the mistake. Describe the case in a truthful manner. They will re-calculate your tax and will inform you that there are a few adjustments required. Being proactive is a sign of good faith and it is more effective in finding solutions.

How to Reverse Marriage Tax Allowance?

Reversing marriage tax allowance is to change who transfers the allowance, or to cancel it and may have roles reversed. In case your circumstances have changed such that the other partner is now earning less than before, you may wish to switch roles. It is a pity that you cannot just change roles on your own. 

The first thing to do is to cancel the current arrangement and reapply online with the partners in reversed positions to obtain marriage allowance. No charge to cancel and reapply, however, timewise. Cancellations usually come into effect at the end of the tax year and new applications may take weeks.

How To Claim Back Marriage Tax Allowance?

In case you have paid more than the necessary tax due to cancellation of marriage allowance during the middle of the year, you might be in a position to receive a marriage allowance refund. HMRC will determine who owes you money when they cancel you.

The refunds are normally automatic in case you are entitled to one. The cash is normally remitted straight into your bank account or by BACS. Alternatively, HMRC could also change your tax code to provide you with the refund by providing you with lower tax deductions in subsequent pay periods.

You can also claim the marriage tax allowance of the past year that has not been claimed. HMRC gives backdating of up to four past tax years and it could be worth more than £1,000.

How Cancelling Marriage Allowance Will Affect Your Personal Allowance?

The partner who transferred part of their allowance will get it back, and the receiving partner will lose the tax savings. HMRC will undo the transfer when you cancel Marriage Allowance. This means the partner who initially gave away part of their personal allowance (up to £1,260) will get their full allowance back (currently £12,570/year). The receiving partner will stop receiving the tax credit. HMRC will adjust your tax codes accordingly.

For example, if you were the lower earner and transferred £1,260 to your spouse, your Personal Allowance would rise from £11,310 back to £12,570. Your spouse would stop receiving the tax credit. It means they would no longer benefit from the annual £252 tax reduction. 

This shift may mean your spouse pays about £252 more in tax over the year, and you will avoid paying unnecessary tax if your income has increased.

What Happens to Marriage Allowance in Case of Divorce?

If you get divorced or dissolve your civil partnership, you’ll no longer be eligible for Marriage Allowance. You should inform HMRC of the change in your circumstances, and they’ll update your tax code accordingly.

Changes to Your Tax Code due to Marriage Allowance

When you claim your marriage allowance, HMRC will update both partners’ tax codes. The lower earner partner, who is the transferring partner,  will gain an ‘N’ suffix.  The higher earner partner, who is the receiving partner, will gain an “M” suffix.

And when the marriage allowance is cancelled, these suffixes will also be removed. The tax code will be reset to your normal tax code by HMRC.

Example: 1131N tax code removal

If the lower earner’s tax code was 1131N, cancelling the marriage allowance will restore it to the standard 1257L code.

How Do I Get My Tax Allowance Back From My Husband

It is an ordinary post-separation question. The allowance transferred is in the possession of the receiving partner until you revoke the arrangement. To reclaim your tax allowance through your husband (or wife) you have to cancel the marriage allowance.

All of your personal allowance comes back to you once cancelled. This normally applies in the following tax year, but HMRC can backdate it in case of separation or divorce.

Keep in mind that the cancellation has consequences on both spouses. Your ex-spouse will lose the extra allowance that he or she was getting and this may make his or her tax bill higher. This may be an unpleasant process, but you need to be sure that your personal tax matters are acuurate.

Transferring Tax Allowance to Spouse – The fundamentals

The basics of marriage allowance is the transfer of tax allowance to spouse. The earner with less income gives a share of 10% of his/her personal allowance (at present £1,260) to his/her partner.

It only works to the advantage of couples in which one of the partners is a basic rate taxpayer and the other is earning less than the personal allowance limit. The partner receiving gets tax cut of up to £252 annually.

To establish this transfer both partners need to coordinate and the earner with lower income has to apply using GOV.UK. The transfer will run automatically every tax year until you change the circumstances or cancel the transfer.

Marriage Tax Allowance If One Partner Is Not Working

The best scenario as regards this benefit is marriage tax allowance when one of the partners is not working. When one of the partners is making no money whatsoever, then they are not spending any of their personal allowance. It is financially sound to transfer some of it to their working spouse.

The non working partner may transfer £1,260 of his or her unused allowance and this may save the couple £252 a year. This is regardless of whether an individual is unemployed, a stay at home parent or a retired individual earning no taxable income.

Although the non-working partner may be getting a few benefits, provided they are not taxable and the total income does not exceed the personal allowance, then they can transfer the allowance.

How Much is Married Tax Allowance Worth?

At the present, in the 2024/25 tax year, marriage allowance can save couples a maximum of £252 each year. This amount is a result of the transfer of £1,260 of personal allowance which lowers the tax bill of the receiving partner by 20% (basic rate) of the same amount.

This accumulates over a number of years. Backdated refunds of more than £1,000 could be owed to the person who has been eligible, but had not claimed the four years. Although £252 per year is not a treasure, it is basically free money, which many couples are not getting. This supplementary income can actually count to households that are on tight budgets.

When Can You Apply for Marriage Allowance?

At what time can you claim marriage allowance? You may make an application at any point in the tax year and provided you are eligible, you may also backdate your claim to a maximum of four past tax years.

Marriage allowance is a benefit that applies to married couples and civil partners where both partners were born on or after 6 April 1935. One of them is required to be a non-taxpayer (earning less than £12,570) and the other a basic rate taxpayer (earning between £12,571 and £50,270).

The application process is simple using the GOV.UK marriage allowance page. You will require the National Insurance numbers of both parties as well as information about the income of the lower earner.

The Bottom Line

It is just as important as knowing how to claim your marriage allowance, to know how to cancel that allowance. You are separated, have a change in income or just no longer feel you are getting a good deal under the arrangement; either way, it is better to cancel early in case it is not right and to prevent any possible complications.

Talk to HMRC via the personal tax account, by phone or even by letter and they will help you through the cancellation process. Do not forget to review your new tax code, and both partners must be aware of it.

But in case you forgot to cancel your marriage allowance, you should not fret. HMRC has a good system of rectifying such situations. The trick is that you need to act the moment you realise there is a necessity to change something.
