Tax free savings income in 202425
If you’ve got savings sitting in a bank or building society account, you might be wondering how much interest you can earn before the taxman comes knocking. The good news is that the Personal Savings Allowance means many UK taxpayers can receive interest completely tax-free in 2024–25. Let’s walk through how it works and whether you’re affected.
Understanding the Personal Savings Allowance
HMRC introduced the Personal Savings Allowance to give individual savers a small buffer before interest becomes taxable. Rather than paying tax on every penny of interest earned, you’re allowed to receive a certain amount tax-free each tax year (6 April 2024 to 5 April 2025).
The allowance varies depending on your income tax band:
- Basic rate taxpayers (earning up to £50,270): £1,000 tax-free savings allowance
- Higher rate taxpayers (earning £50,271 to £125,140): £500 tax-free savings allowance
- Additional rate taxpayers (earning over £125,140): No allowance
The key point here is that your allowance depends on your marginal tax band, not your total income. If you’re a basic rate taxpayer earning £30,000, you get the full £1,000 allowance regardless of how little you earned the previous year.
How it works in practice
Let’s say you earned £40,000 salary in 2024–25 and your savings earned £800 in interest. Because £800 falls within your £1,000 basic rate allowance, you pay no tax on that interest. Simple.
However, if your savings earned £1,500 in interest, you’d only be taxed on the excess: £500 × 20% = £100 tax due.
For higher rate taxpayers, the maths is tighter. If you earn £80,000 and your savings generate £600 in interest, you’d pay tax on £100 of it (the amount over your £500 allowance) at 40%, giving you a bill of £40.
It’s worth noting that from April 2024, the Personal Savings Allowance replaced the previous Personal Savings Accounts approach. Banks now report gross interest to HMRC automatically, and you only need to declare taxable interest if you’re completing a Self Assessment tax return.
Who needs to declare savings income?
If you’re employed and your total income (including interest) stays within the basic rate band, and you have no other untaxed income, you likely won’t need to file a Self Assessment return at all. Your savings interest will be covered by your allowance, and you’re done.
However, you must declare savings interest if:
- You’re self-employed
- You have multiple sources of income that push you into higher or additional rate tax bands
- You’re a director or have rental income
- You receive interest that exceeds your allowance
- You’ve received a notice to file from HMRC
Many people assume they don’t need to declare because their interest sits within the allowance—but if you meet any of the above criteria, declaration is still a requirement, even if no tax is ultimately due.
Maximising your tax-free savings
Given that basic rate taxpayers can receive £1,000 tax-free, it makes sense to use this allowance efficiently. If you’re earning close to the basic rate threshold, you might prioritise building your savings here rather than extending income that could tip you into higher rate tax.
If you’re self-employed, managing your income carefully can help you stay within the basic rate band and preserve that larger allowance. Conversely, if you’re already paying higher rate tax, the reduced £500 allowance is still worth having—don’t leave it unused.
It’s also worth checking your savings account regularly. Interest rates have been volatile, and the interest your savings generate might surprise you. An easy way to stay on top of things is to request an annual interest statement from your bank or building society.
What about Premium Bonds and ISAs?
Premium Bond prizes and Individual Savings Account (ISA) interest are completely outside the Personal Savings Allowance—they’re already tax-free by design. If you’re a higher rate taxpayer concerned about using your reduced allowance efficiently, maximising ISA contributions is a smart strategy.
Wrapping up
The Personal Savings Allowance is a genuine benefit for UK savers, particularly those in the basic rate band. The 2024–25 thresholds remain unchanged from the previous year, giving you consistency as you plan. The best approach is to understand which band you fall into, keep track of your interest, and make sure you’re declaring it correctly if required.
