The 40% higher rate begins at £50,270 in England, Wales and Northern Ireland. But crossing that line costs you more than just 40% on the top slice. Here is the full picture, including the knock-on effects most guides miss.
The higher rate tax threshold is the most consequential line in the UK tax system after the Personal Allowance, because crossing it changes far more than the rate on your top slice of income. For 2025/26 the 40% higher rate begins at £50,270 in England, Wales and Northern Ireland, a figure that has not moved since 2021 and will not move before April 2028. The frozen threshold is steadily turning ordinary earners into higher-rate taxpayers for the first time.
Most people understand that income above this line is taxed at 40%. Far fewer realise that the same threshold quietly triggers a cascade of other changes: a smaller savings allowance, a possible Child Benefit clawback, and a richer rate of pension relief. This guide covers the headline figure and all of those second-order effects, because that is where the real money sits.
The £50,270 figure is not a standalone number; it is the sum of two parts. You receive a £12,570 Personal Allowance taxed at 0%, then a £37,700 basic rate band taxed at 20%. Stack them and you reach £50,270, the exact point your next pound is taxed at 40%.
| Component | Amount (2025/26) | Rate on this slice |
|---|---|---|
| Personal Allowance | £12,570 | 0% |
| Basic rate band | £37,700 | 20% |
| Higher rate threshold | £50,270 | 40% begins above this |
| Additional rate threshold | £125,140 | 45% begins above this |
The higher rate then runs all the way from £50,271 to £125,140, where the 45% additional rate takes over. For the full set of bands across the UK, see our guide to income tax rates and thresholds, which sets out every rate including the 45% additional band above.
Tax is marginal, so it is worth seeing precisely how a salary above £50,270 is taxed. Consider Marcus, an employee earning £62,000 in 2025/26 with a standard 1257L code:
Marcus pays £12,232 in income tax. His marginal rate is 40%, but his effective rate is just under 20%, because most of his income was taxed at lower rates first. If he received a £1,000 bonus, he would keep £600 of it; crossing into the higher rate does not somehow shrink his earlier income. You can test your own salary against the threshold with the salary tax calculator.
This is the part most guides skip, and it is the most important section on the page. The higher rate threshold is also a trigger for several other tax changes that arrive the moment you pass it.
A basic-rate taxpayer gets a £1,000 Personal Savings Allowance, letting them earn £1,000 of interest tax-free. The instant you become a higher-rate taxpayer, that allowance drops to £500. On today's interest rates that change alone can add tax to a few thousand pounds of savings you previously held tax-free.
If you or your partner claim Child Benefit, the High Income Child Benefit Charge starts to claw it back once the higher earner's adjusted net income exceeds £60,000, with full withdrawal by £80,000. This sits just above the higher rate threshold and catches many families by surprise. The charge is collected through Self Assessment.
Not every effect is negative. Higher-rate taxpayers receive 40% tax relief on personal pension contributions and Gift Aid donations, rather than the 20% a basic-rate payer gets. The extra 20% is usually reclaimed through Self Assessment or by asking HMRC to adjust your code. Because pension contributions also reduce your adjusted net income, they can pull you back below £50,270 and undo the other effects above.
People obsess over the 40% rate, but the quiet stuff, the halved savings allowance and the Child Benefit clawback, is where crossing £50,270 really bites. Know the whole picture before you assume a pay rise is all profit.
If you are a Scottish taxpayer, with an S prefix on your tax code such as S1257L, the higher rate threshold is a different number entirely. Scotland's higher rate is 42% rather than 40%, and it begins at £43,663, well below the £50,270 used elsewhere in the UK.
| Scottish band around the higher rate | Taxable income | Rate |
|---|---|---|
| Intermediate rate | £27,492 to £43,662 | 21% |
| Higher rate | £43,663 to £75,000 | 42% |
| Advanced rate | £75,001 to £125,140 | 45% |
The effect is real money. A Scottish taxpayer earning £50,000 is already a 42% higher-rate payer on part of their income, while an English taxpayer on the same salary is still entirely within the 20% basic rate. The £12,570 Personal Allowance is identical, but everything above it diverges. Wales, by contrast, uses a C-prefix code and currently mirrors England exactly, so the Welsh higher rate is 40% at £50,270.
You may see the higher rate appear directly in a tax code. A D0 code instructs payroll to tax all of that income at 40% with no Personal Allowance, and it is normally applied to a second job or a second pension where your allowance and basic rate band are already fully used by your main income. The Scottish version is SD0 and the Welsh version is CD0.
A D0 code is correct when it is doing its job, taxing additional income that genuinely all falls in the higher band. It is wrong, and expensive, if it has been applied to your only source of income, because you would lose your Personal Allowance and basic rate band entirely. If a D0 code appears unexpectedly, check it before months of overpayment accumulate.
For the self-employed, the £50,270 threshold applies to taxable profit in the same way it applies to a salary. A sole trader pays 40% on profit above £50,270, plus Class 4 National Insurance charged separately on top.
There is a meaningful overlap to flag. Making Tax Digital for Income Tax begins in April 2026 for sole traders and landlords with qualifying income above £50,000, a figure that sits right next to the higher rate threshold. That means a large share of higher-rate sole traders will be in the very first MTD wave, required to keep digital records and file four cumulative quarterly updates plus a final declaration. The £30,000 threshold follows in April 2027 and £20,000 in April 2028.
