While politicians debate the future of the Personal Allowance, existing HMRC rules already offer a legitimate way to raise your tax-free earnings ceiling by thousands of pounds. By combining two separate schemes – Marriage Allowance and Rent a Room – taxpayers can effectively enjoy a personal tax-free allowance of £21,330, even as the government holds off on any immediate changes.
The standard Personal Allowance stands at £12,570 for most people. Marriage Allowance can transfer £1,260 of that allowance to a spouse or civil partner, while Rent a Room lets you earn up to £7,500 tax-free from letting out a furnished room in your home. Together, these add £8,760 to the baseline, reaching the £21,330 figure.
How Marriage Allowance Works
Marriage Allowance allows you to transfer £1,260 of your tax-free Personal Allowance to your husband, wife, or civil partner. This reduces the receiving partner’s tax bill by up to £252 per year. Designed for couples where one person earns less than the Personal Allowance, the relief ensures that the higher-earning partner can make use of the unused allowance.
Importantly, HMRC permits backdating. Couples can claim for any tax year since 6 April 2022 (the 2022-to-2023 tax year) as long as they were eligible. This means a couple who only recently discovered the relief could receive a rebate covering multiple years. For example, a five-year claim could be worth well over £1,000.
Rent a Room: Earn £7,500 Tax-Free
Meanwhile, the Rent a Room Scheme provides a tax-free allowance of £7,500 per year for income from letting out furnished accommodation in your home. This applies whether you rent a single room or an entire floor, as long as it’s within your main residence. The threshold is halved to £3,750 if you share the rental income with another person, such as a spouse or business partner.
The scheme is automatic if your gross rental income stays below the threshold. In other words, you don’t need to do anything – no tax return, no paperwork. Only if you earn more than the threshold do you need to complete a tax return. In that case, you can choose to opt into the scheme and claim the £7,500 allowance, or instead record your actual income and expenses on the property pages of your tax return.
Combining the Two for Maximum Benefit
Combining these two reliefs can significantly increase your effective tax-free income. For instance, a married person who lets out a room and claims the full Rent a Room allowance, while also benefiting from Marriage Allowance, would see their personal tax-free allowance rise from £12,570 to £21,330. That equates to a potential tax saving of hundreds of pounds each year, depending on your marginal rate.
HMRC’s own guidance confirms the Marriage Allowance figures: “Marriage Allowance lets you transfer £1,260 of your Personal Allowance to your husband, wife or civil partner. Your Personal Allowance is the amount you can earn before paying tax. This reduces their tax by up to £252 in the tax year (6 April to 5 April the next year).”
Andy Burnham’s Position on Personal Allowance
The political backdrop to these schemes is the ongoing debate over the Personal Allowance. Andy Burnham, the Labour politician, previously told The Times that the “frustration about the personal allowance” he had heard while campaigning in the Makerfield by-election was “lodged in my mind.” However, people close to Burnham later indicated to BBC News that any changes to the Personal Allowance are not part of his initial plan to tackle the cost of living.
Asked directly whether he would make changes to the income tax allowance, Burnham said: “It's funny these days you can't answer a question honestly without people then reading everything else into it. I want to answer questions honestly in this job, as I said before. I think that's all about trust in politics and doing politics differently, and I'm determined to keep working in that way. It's just perhaps the way politics is these days and the way people report things, but that was an honest answer.”
He added: “There is no commitment at this point to change, but we will look at that at the Budget.” This leaves no immediate alteration to the Personal Allowance, making it even more important for taxpayers to use existing reliefs.
Key Takeaways
- Marriage Allowance transfers £1,260 of Personal Allowance, saving up to £252 a year.

- Rent a Room offers a £7,500 tax-free allowance, or £3,750 if shared.
- Combining both can produce a total effective allowance of £21,330.
