Divorce and the Marriage Allowance in 2026/27: Reclaiming or Cancelling £1,260

Quick answer

A divorce does not switch off the Marriage Allowance by itself: the £1,260 transfer keeps running until you or your former partner tells HMRC to stop. When you cancel because of a separation, it ends at the close of the current tax year, restoring the transferring partner's full £12,570 Personal Allowance from the following 6 April. Decide quickly who benefits, because leaving it in place can hand your ex an up-to-£252 saving funded by your allowance.

How the Marriage Allowance works in 2026/27

The Marriage Allowance is a transfer between spouses or civil partners. The lower earner gives up £1,260 of their £12,570 Personal Allowance, reducing their own allowance to £11,310. The higher earner, who must be a basic-rate taxpayer, receives that £1,260 as a tax credit worth 20%, cutting their bill by up to £252 for the year.

To qualify in England, Wales and Northern Ireland the recipient must earn between £12,570 and £50,270, keeping them in the 20% basic-rate band. The person transferring usually earns under £12,570, so they pay no tax even after giving up part of their allowance. If you want to model how the bands interact with your income, the

Why divorce does not end the transfer automatically

Many people assume that once the decree absolute (now called the final order) arrives, all the tax links between them dissolve too. That is not how the Marriage Allowance works. HMRC treats the transfer as a standing instruction that continues year after year until cancelled or until eligibility ends. A change in marital status does not reach HMRC's tax records unless someone reports it.

This matters because tax codes are adjusted to reflect the transfer. The recipient often has an "M" suffix on their code and the transferring partner an "N" suffix. If the transfer is left running after divorce, the wrong allowances flow through PAYE all year, and one of you may end up underpaying or overpaying. The cleaner approach is to deal with it at the point of separation rather than waiting.

Cancelling: who does it and when it takes effect

Either former partner can cancel, but the timing rule depends on the reason. When you cancel because of divorce, dissolution or separation, the change applies from the end of the tax year in which you cancel. So if you cancel in, say, November 2026, the transfer still applies for the whole of 2026/27 and only stops from 6 April 2027. This protects the recipient from a sudden in-year clawback.

If the person who received the allowance cancels for a non-divorce reason, HMRC may instead backdate the cancellation to the start of the tax year, which can create an underpayment to settle. For most separating couples, the transferring partner is the one who wants to act, because cancelling restores their full £12,570 allowance going forward. You can cancel through your Personal Tax Account online or by phoning HMRC; have your National Insurance number ready.

Reclaiming relief you missed

Divorce is also a moment to check whether you ever claimed relief you were entitled to. New Marriage Allowance claims can be backdated up to four tax years, provided you met the conditions in each of those years. If you were eligible but never applied, you could recover up to four years of relief at up to £252 a year. That backdated claim can still be made even as a marriage is ending, as long as you both qualified during the relevant years.

The reverse is not true for the recipient. Cancelling does not let HMRC reach back and recover the saving for past years; it simply stops the future benefit. So if you received the allowance, there is no windfall in cancelling, only the loss of the up-to-£252 going forward. Check your wider position too, because divorce can change your

band if maintenance, pension sharing or a salary change shifts your income.

Devolved differences: Scotland, Wales and Northern Ireland

The £1,260 transfer amount is identical across the whole UK because the Personal Allowance is set by Westminster. What differs is the band the recipient must sit in. In England, Wales and Northern Ireland the recipient must be a basic-rate (20%) taxpayer earning up to £50,270.

Scotland operates its own income tax bands. To receive the Marriage Allowance in Scotland, the recipient must pay no more than the intermediate rate of 21%, which runs up to the £31,092 threshold for 2026/27. Above that, into the higher (42%) or advanced (45%) Scottish bands, eligibility is lost. The saving is calculated on Scottish rates, so it will not be exactly £252. Wales uses the same income tax bands as England and Northern Ireland for this purpose, so Welsh couples follow the standard rules. If you are a Scottish taxpayer untangling finances, the

tool helps you confirm which band you fall into after divorce.

Practical steps when you separate

First, agree who keeps or cancels the transfer. If you transferred your allowance away, cancelling restores your full £12,570 Personal Allowance and protects you if your income rises post-divorce. Second, cancel promptly online or by phone so the change lands at the correct year-end. Third, check your tax code after the new tax year starts to make sure the "M" or "N" suffix has been removed. Finally, review whether a backdated claim could recover up to four years of relief if you never used the allowance while eligible. Sorting the Marriage Allowance is a small task that prevents an unwelcome tax surprise later.
