Higher Rate Tax Explained — 40% Tax in the UK

The higher rate of income tax — 40% in England, 42% in Scotland — is a common source of confusion. Many people think they'll lose nearly half their income once they breach the threshold, but that's not how the banded system works.

When Does 40% Tax Apply?

In England, Wales and Northern Ireland, the higher rate (40%) applies to income above £50,270in 2026/27. Only the income above that threshold is taxed at 40% — the rest is still taxed at 20% (basic rate) and 0% (personal allowance).

In Scotland, the higher rate (42%) begins at £43,663. Scotland also has an Advanced Rate of 45% above £75,000.

How Much Extra Tax Does Higher Rate Mean?

The basic rate band covers £37,700 of income (from £12,571 to £50,270). The maximum tax you pay in the basic rate band is £7,540 (20% × £37,700). After that, each extra pound costs 40p.

How to Reduce Higher Rate Tax

• Pension contributions via salary sacrifice: Each £1 contributed reduces taxable income by £1, pushing it below the 40% band. If you're just over £50,270, even a modest pension contribution can save the 40% rate on that portion.
• Gift Aid: Charitable donations via Gift Aid extend your basic rate band by the grossed-up donation amount — effectively shifting some income back into the 20% band.
• Claim via Self Assessment: If your employer can't apply higher-rate relief directly, submit a Self Assessment return to reclaim the additional 20% on pension contributions or Gift Aid.
• Use your ISA allowance: While not a tax deduction, keeping investments and interest inside an ISA prevents that income from adding to your taxable total.
