Therefore, if, as a couple, you’re eligible, you can make a tax saving. When you apply for marriage allowance, you can transfer part of your allowance to your spouse or civil partner. 

The process of transferring personal allowance to spouse 

Transferring tax allowance to spouse

The marriage tax allowance transfer will allow one partner to transfer part of their Personal Allowance (PA) to the other partner. If you’re the lower earner, you can transfer 10% of your personal allowance to your partner. Therefore, to reiterate, the transfer of the married person allowance is 10% of the lower-earner partner’s PA to the higher-earner.

In 2022/23 and 2023/24, the PA is £12,570. Therefore, when you’re the lower-earning partner, you can transfer £1,260 of your personal allowance to your partner. This’ll result in additional tax relief. In turn, the higher-earning spouse receives the allowance transfer, and it reduces their tax by £1,260.

The entitlement to claim spouse tax allowance transfer (UK) will depend on the income of both people in the marriage or civil partnership. 

When do you qualify for the UK marriage allowance transfer?

To be eligible for marriage tax allowance transfer, you must satisfy the following criteria:

  • You’re married or in a civil partnership.
  • You were both born after 5 April 1935. If one or both individuals were born before this date, you’d need to claim for the ‘married couple’s allowance’ instead.
  • One partner will have total taxable income below the personal allowance of £12,570. Your total taxable income includes any salaries or self-employment profits. It also includes dividends, other taxable income, job seekers allowance, Universal Credit and state pension. The second partner will be a basic rate taxpayer earning more than the personal allowance and be paying income tax at the basic tax rate. However, they’ll not be in the higher rates tax bracket, which is income above £50,270 in 2022/23 and 2023/24.

If you claim for the married couples tax allowance, the lower income earner can transfer precisely 10% of the prevailing PA for the tax year in question.

It may be the case that the lower income earner does have some taxable income. This could be in the form of salary or some other income. When this is the case, the amount of personal allowance transfer may be less than the 10% mentioned above depending on what their total income is.
