In this easy-to-understand guide, we'll talk about the Marriage Allowance, how it works, eligibility criteria, and practical application for claiming. Whether you've just gotten married or have been together for years, you will learn how this simple yet powerful allowance can keep a few pounds in your pocket.
What Is the Marriage Allowance?
It is a tax relief granted by HM Revenue and Customs to married couples or civil partners. One partner is allowed to transfer part of their personal tax allowance to the other, thus minimizing the couple's overall tax liability.
For the 2024/2025 tax year, the personal allowance stands at £12,570, out of which up to £1,260 can be passed onto an individual's spouse or civil partner, potentially permitting income tax savings of up to £252 annually.
Are You Eligible to Claim the Marriage Allowance?
To be eligible for Marriage Allowance, you need to satisfy these conditions:
- You must be married or in a civil partnership.
- One partner must earn less than the personal allowance (£12,570).
- The other partner must be a basic rate taxpayer, earning between £12,571 and £50,270.
Example Scenario:
Let's look at Sarah and Tom. Sarah works part-time and earns £10,000 per annum, which is lower than the personal allowance. Tom looks at his calendar while working full-time and earning €30,000 per year and comfortably fits into the basic rate tax band.
Sarah transfers £1,260 of her unused allowance to Tom. Tom's personal allowance rises effectively to £13,830, and the amount of tax paid decreases: savings go to £252 dollars per annum.
