The new tax year, which began in April, has brought a reset of various tax-free allowances, including HMRC schemes that allow you to increase your tax-free Personal Allowance fully legally. Despite the extended freeze on tax thresholds, you can boost your allowance beyond the basic £12,570 by participating in a scheme allowed by HMRC and submitting a self-assessment tax return for this tax year.
Understanding Fiscal Drag
Tax thresholds have been frozen for five more years, leading to increased 'fiscal drag.' This phenomenon pushes more people into paying tax for the first time or into higher tax bands as inflation drives wages up. The standard income tax Personal Allowance remains at £12,570 and will stay at that level until at least 2031. This is the maximum amount you can earn before paying 20% tax on income between £12,570 and £50,270, 40% on earnings over that, and 45% on every pound over £125,140 for additional rate taxpayers.
The Rent-a-Room Scheme
You can boost your Personal Allowance to up to £20,070 with tax-free earnings of £7,500 through the rent-a-room scheme. This scheme allows you to earn up to £7,500 from letting out a furnished room in your home without paying tax, provided you live in the property. The allowance cannot be used for buy-to-let income. You must declare the income on a self-assessment tax return. If you earn £7,500 or less (£625 per month), you are exempt from tax on that income.
By combining the £12,570 Personal Allowance with the £7,500 rent-a-room allowance, you can enjoy a total tax-free income of £20,070. If you share the income with a partner, you can split the allowance, each claiming £3,750 extra, boosting your tax-free allowance to £16,320 per person.
Opting Out and Other Considerations
You can opt out of the scheme and have the rent-a-room income taxed normally. This might be beneficial if you incur a loss from renting (e.g., after extensive refurbishment) and want to offset that loss against tax on other property income. The government explains: "The Rent a Room Scheme lets you earn up to a threshold of £7,500 per year tax-free from letting out furnished accommodation in your home. The threshold is halved to £3,750 if you share the income with someone else."
You can let out as much of your home as you want. The tax exemption is automatic if you earn less than your threshold, meaning you do not need to do anything. However, you must complete a tax return if you earn more than your threshold. You can then opt into the scheme and claim your tax-free allowance on your tax return. Alternatively, you can choose not to opt in and record your income and expenses on the property pages of your tax return.
