Marriage and Married Couple's Allowance

You don’t usually pay Income Tax on all of your taxable income. This is because most people qualify for one or more allowances. An allowance is an amount of otherwise taxable income that you can have tax-free each tax year. This guide provides a simple explanation of how the Marriage and Married Couple’s Allowance works. These allowances are usually increased each year and normally apply from the start of the tax year (6 April).

Marriage Allowance

Married couples and those in civil partnerships can transfer up to £1,250 of personal allowance (10% of the £12,500 personal allowance for 2019/20) to their partner for 2019/20 and is sometimes known as the Marriage Tax Allowance.

You might be eligible for this if:

  • you’re married, or in a civil partnership and are not in receipt of Married Couple’s Allowance
  • one of you earns less than the Personal Allowance so is not liable to tax or liable to tax at the higher or additional rates. This means an income of less than £12,500 while your partner is a basic rate taxpayer with income between £12,501 and £50,000
  • you were born after 6 April 1935. If you weren’t, you might be able to get Married Couple’s Allowance.

If you’re eligible, married couples and civil partners, but not unmarried couples, can transfer 10% of their Personal Allowance (£1,250 in 2019/20) to their partner. This means the partner who earns more will get £1,250 added to their Personal Allowance (the amount you can earn before having to pay tax on your income).

20% of this allowance is given as a reduction in your tax bill (unlike the Personal Allowance which is deducted from your taxable income before tax is worked out).

Here’s an example.

If you earn £30,000 a year, which means you’re a basic rate taxpayer, and your partner earns £8,000 a year and so is a non-rate taxpayer, your household could be £250 better off:

Partner 1

  Without Marriage Allowance Including Marriage Allowance
Income £30,000 £30,000
Personal Allowance £12,500 £13,750
Income Tax £3,630 £3,392
Tax saving 0 £250

Partner 2

  Without Marriage Allowance Including Marriage Allowance
Income £8,000 £8,000
Personal Allowance £12,500 £11,250
Income Tax £0 £0
Tax saving 0 £0

In this example, once the non-taxpayer (Partner 2) earns over £11,250 (the difference between the standard personal allowance of £12,500 and the amount that’s been transferred, £1,250), this becomes less beneficial. This is because the non-taxpayer would pay tax on income over £11,250 rather than £12,500.

The recipient partner’s tax code will usually change to ‘M’, to show they are receiving marriage allowance from their spouse. If the partner who transferred their personal allowance is in employment, their tax code will change to ‘N’, showing they have elected to use the marriage allowance.

Claiming Marriage Allowance for previous years

You need to meet the criteria for each year you apply for. Keep in mind that the threshold for non-taxpayers and basic rate taxpayers is different according to the tax year you are claiming for. You can backdate your claim for up to four years.

This could be worth up to £1,150, including the £250 saving for the current tax year.

Claiming Marriage Allowance if your partner has died

If your partner died after 2015, and you meet the other criteria for Marriage Allowance, you can still apply for the benefit.

You’ll be applying for a backdate of the benefit, so you’ll get the benefit as if you had applied for it from April 2015.

This will be worth up to £1,150, but you’ll only get payments for the years in which both of you were alive.

Married Couple’s Allowance

Instead of the Marriage Allowance, couples where one or both partners are born before 6 April 1935 may be able to claim a more generous allowance, called Married Couple’s Allowance.

For marriages before 5 December 2005, the husband’s income is used to work out Married Couple’s Allowance although it can be transferred to the wife.

For marriage and civil partnerships after this date, it’s the income of the highest earner.

Tax relief for the Married Couple’s Allowance is given at the rate of 10%. This means that the higher earning partner gets 10% of the tax they pay.

The benefit has upper and lower limits for both the amount of tax that can be claimed and how much that can be earned.

For the 2019 to 2020 tax year, this could cut your tax bill between £345 and £891.50 a year.

The easiest way to check how much you’ll get is to use the calculator on the GOV.uk website.

You can claim Married Couple’s Allowance in your Self Assessment tax return or if you don’t fill one out, you can get in touch with HMRC with details of your marriage or civil partnership ceremony and the details of your spouse or civil partner.
