Budget 2026 Savings Tax Changes Explained: What UK Savers Need to Know

A Surprise Hike for Savers in the 2026 Budget

Wednesday's budget delivered mixed news for UK savers. In his inaugural appearance as chancellor, John Healey reversed a previously announced plan to slash the cash ISA contribution limit for those under 65, but then introduced an unexpected extra tax charge on savings and property income. His predecessor, Rachel Reeves, had already set out a proposal to raise income tax rates for savers and landlords, scheduled to take effect in April 2027. Healey went a step further, tacking on an additional two percentage points to each bracket.

Jason Hollands, managing director at wealth manager Evelyn Partners, characterised the higher rates as a "sting in the tail" for those relying on interest income. He acknowledged, however, that there are practical measures savers can take to soften the blow, noting that the optimal approach will vary depending on individual circumstances.

What the New Tax Rates Mean in Practice

The revised rates, which apply across the UK, stand at 24% for basic-rate taxpayers, 44% for higher-rate taxpayers, and 49% for those paying the additional rate. They kick in on 6 April of the relevant tax year.

The practical implication is that finding a savings account whose after-tax return outpaces inflation becomes significantly more difficult, particularly if inflation remains elevated next year as many forecasters expect.

Anna Bowes, a personal finance specialist at advice firm The Private Office, illustrated the challenge with a 3.5% inflation scenario. Under the new tax regime, a basic-rate saver would need to secure 4.61% gross interest simply to preserve the real value of their money. A higher-rate taxpayer would need 6.25%, and an additional-rate taxpayer would need 6.86%. Bowes noted that, as far as she is aware, the two higher thresholds are currently unattainable on any standard savings account.

Tax-Free Allowances That Still Protect Your Interest

Despite the higher headline rates, several allowances continue to shield a portion of savings income from tax entirely.

Cash ISAs. Interest earned on money held within a cash ISA is completely tax-free. The annual contribution cap remains at £20,000 per tax year. This was originally slated to be reduced to £12,000 for anyone under 65 from April 2027, but Healey has withdrawn that proposal. Once funds are inside a cash ISA, they are protected from tax indefinitely, provided they are not withdrawn. You are free to switch providers to chase better rates, subject to each account's specific terms.

Personal allowance. The standard tax-free personal allowance for the 2026-27 year is £12,570. This applies to all income, including wages, pensions, and savings interest. If your employment or pension income does not fully consume this allowance, HM Revenue and Customs will apply the remaining amount to your savings interest before any tax is charged.

Personal Savings Allowance (PSA). On top of the personal allowance, basic-rate taxpayers can receive up to £1,000 of interest each financial year without a tax bill, while higher-rate taxpayers get £500. Additional-rate taxpayers receive no PSA at all. A few years ago, exceeding these thresholds required a very large savings balance, but with accounts currently offering 5% or more, it is far easier to trip over the limit. To illustrate: a basic-rate taxpayer depositing £20,000 into a non-ISA account paying 5% will earn exactly £1,000 in annual interest, exhausting their entire PSA. Any interest above that threshold is taxed at 24%. For a higher-rate taxpayer, just £10,000 in the same 5% account would wipe out their £500 PSA, with everything beyond taxed at 44%.

Starting rate for savings. Low-income earners may also qualify for an additional tax-free layer of up to £5,000 of interest, on top of the PSA. To be eligible, your other income (wages, pension, etc.) must fall below £17,570 per year. The ISA allowance governs how much you can deposit each year, whereas the PSA is calculated on the interest you actually receive.

Strategies to Reduce Your Overall Savings Tax Bill

Review where your money sits. Experts consistently advise keeping a readily accessible emergency fund, so a modest tax bill should not deter you from maintaining liquidity. That said, Hollands cautions that holding more cash than you realistically need over the coming years may mean forgoing the potential of longer-term investment growth.

Couples should pool their allowances. If you are married or in a civil partnership, Hollands recommends reviewing your combined savings and allowances. If both partners have maxed out their ISA and PSA contributions but one pays tax at a lower rate, transferring cash to the lower-earning partner can reduce the household's overall tax burden. He stressed, however, that this must be a genuine transfer: the money becomes the recipient's legally and in practice, and they must be free to decide what to do with it, making trust essential.

Consider children's accounts. If you are building a fund for a child's future, holding it in their name rather than your own can be advantageous. You can pay into a child trust fund, contribute to an existing junior ISA, or open a new one. The annual limit for a junior ISA is £9,000, and all returns are tax-free. One caveat: if the child earns more than £100 in interest from money a parent has put in their account, the parent is taxed on those returns. This rule does not apply if the funder is a grandparent.

Factor in pensions and mortgage overpayments. Dan Coatsworth, head of markets at AJ Bell, highlighted the double benefit of pension contributions: you receive tax relief at your highest marginal rate and simultaneously lower your adjusted net income. "Not only does it mean you pay less tax on your income, but it could also help bring you back below other tax thresholds, while helping boost your prospects for retirement at the same time," he explained. The trade-off is that pension money is locked in until retirement. Overpaying on your mortgage is another avenue worth examining for those with substantial cash reserves.

Look beyond standard savings accounts. For cash you need to keep accessible, premium bonds offer a tax-free alternative. Prizes are exempt from tax, each person in the UK can hold up to £50,000, and the bonds are government-backed. The prize fund has recently been increased, giving each bond a 21,000-to-1 chance of winning.

Both Hollands and Coates also pointed to low-coupon, short-dated gilts as a viable alternative. These UK government bonds pay a small annual interest rate and are set to mature within the next couple of years. Crucially, the return received at maturity is not subject to capital gains tax. They can be purchased through an investment platform and held either inside a stocks and shares ISA or outside it, though platform fees will apply. Hollands noted that because most of the return derives from the CGT saving at maturity, these instruments can deliver very attractive after-tax returns compared with the post-tax interest on a conventional cash account, particularly for those paying the higher and additional tax rates.
