In the UK, you can save up to £20,000 per tax year in ISAs entirely tax-free. Beyond ISAs, you can earn tax-free interest on other savings via the Personal Savings Allowance (PSA): £1,000 for basic-rate taxpayers and £500 for higher-rate taxpayers. There is no limit on total savings amounts, only on interest earned and annual contributions.
For the 2025/26 tax year, you can contribute up to £20,000 into a tax-free Individual Savings Account (ISA). This amount can be split between different types of savings accounts, or you can choose to invest the full £20,000 in one account before having to pay tax on it.
Individual Savings Accounts (ISAs)
The government sets a maximum amount that you can invest in ISAs. Until 2031 the annual limit is £20,000. You pay no Income Tax on the interest or dividends you earn within an ISA and any profits from investments are free of Capital Gains Tax.
ISAs offer tax-free savings, with interest earned inside an ISA not counting toward your PSA. If your savings interest exceeds your allowances, HMRC may collect tax via PAYE or require you to file a Self Assessment return, especially if your savings and investment income is over £10,000.
The amount of interest you can earn on your savings will depend on your tax bracket: Basic-rate taxpayers (20%) – tax-free interest up to £1,000. Higher-rate taxpayers (40%) – tax-free interest up to £500. Additional-rate taxpayers (45% or higher) – no tax-free interest on savings.
If you earn less than £17,570 a year, you can earn up to £5,000 a year in savings/investment returns before being taxed on it. This is known as the 'starting rate for savings'. Your exact limit will depend on the exact amount you earn. If you earn £12,570 or less, you'll get the full £5,000 allowance.
The TFSA (Tax-Free Savings Account) annual contribution limit is $7,000 for 2024, 2025, and 2026, while the cumulative limit for someone who has been eligible since 2009 and never contributed can reach up to $109,000 in 2026. Contribution room increases yearly, starting from age 18, and you can check your personal limit via the Canada Revenue Agency (CRA) My Account website.
If your savings are only held in ISAs, or other tax-free savings/investment products, you won't need to pay any tax on money you make in interest or returns, no matter how much you make.
To avoid the UK's 60% tax trap (an effective 60% rate on income between £100k-£125k), the key is to reduce your adjusted net income back below £100,000 by making tax-efficient contributions, primarily via pension contributions, which reclaim your full £12,570 Personal Allowance, and also through salary sacrifice for benefits like childcare or cycle-to-work, and Gift Aid donations to charity.

The five key mistakes to avoid in a TFSA are over-contributing (and re-depositing withdrawals in the same year), treating it like a basic savings account (missing out on investment growth), failing to track your room (relying solely on CRA data), improperly moving funds (withdrawing and redepositing instead of transferring), and investing in non-qualified assets or high-risk trades (like day trading or certain foreign stocks that incur withholding tax).
Yes, it is possible for HMRC to access your business or personal bank account, but it cannot do this freely. To see your bank records, it must have a reasonable belief that you have underpaid tax or failed to declare income, and it must follow a set legal process.
ISAs. ISAs allow you to save up to £20,000 each tax year, with no income tax to pay on your returns. They come in various forms, including easy access and fixed rate accounts, of if you're saving for the long term, a Lifetime ISA could be worth considering.
Is £100,000 savings good in the UK? Yes. £100,000 is five times the annual ISA tax-free savings allowance and approximately ten times the UK average in savings. But if your AER (Annual Equivalent Rate) is lower than the rate of inflation, your money will lose value every year.
Therefore, it's wise for savers with substantial savings to avoid holding more than £120,000 in any one bank to ensure full protection under the FSCS. This limit was raised to £120,000 from £85,000 on 1 December 2025.
Over-contributions – If you contribute too much to your TFSA, you'll pay a penalty of 1% per month on the excess amount until you remove it. If you over-contribute deliberately, you'll pay a 100% tax on any gains or income you make on the excess amount.
