What Is Higher Rate Tax? The 40% Band Explained

Cross £50,270 of taxable income in 2025/26 and you become a higher rate taxpayer. That sounds alarming, but the 40% charge applies only to the slice of income above that threshold, not to a single penny you earned below it. A sole trader turning over £60,000 after expenses does not suddenly hand over 40% of their entire profit to HMRC; they pay 40% on roughly £9,730 of it. The difference between those two calculations is about £17,600, which is why the misconception costs people real panic (and occasionally bad financial decisions).

How the 40% Band Actually Works in 2025/26

UK Income Tax is structured in bands, each applying a different rate to a different slice of income. You can see how all the slices fit together on the UK tax bands overview, but the higher rate band sits immediately above the basic rate band.

For a straightforward employee or sole trader with no other income, the bands for 2025/26 stack like this:

Note that Scotland uses different Income Tax bands set by the Scottish Parliament; the figures above apply to England, Wales and Northern Ireland.

A Worked Example: Freelance Consultant Earning £68,000

Suppose you are a self-employed consultant whose taxable profit for 2025/26 is £68,000.

• Personal Allowance: £12,570 taxed at 0% = £0
• Basic rate band: £37,700 (the gap between £12,570 and £50,270) taxed at 20% = £7,540
• Higher rate band: £17,730 (the gap between £50,270 and £68,000) taxed at 40% = £7,092
• Total Income Tax: £14,632

You can plug your own numbers into the salary and income tax calculator to see the exact split for your situation, including National Insurance.

The consultant's overall (average) tax rate is 21.5%, not 40%. The higher rate only raised her total bill by £7,092, the 40% chunk. That is significant money, but it is not the catastrophe that "you're a 40% taxpayer now" can imply.

Who Reaches the Higher Rate Threshold?

Employees with multiple income streams

Salary alone pushes many senior employees past £50,270, but the threshold catches others less obviously. If your PAYE salary is £44,000 and you earn £10,000 of freelance income on the side, £3,730 of that freelance income falls into the 40% band. HMRC combines all taxable income sources: employment, self-employment, rental income, savings interest above the Personal Savings Allowance, and dividends above the £500 dividend allowance.

Sole traders with a strong year

A good year can push profit past the threshold unexpectedly. A plumber whose turnover jumps after taking on a commercial contract, a freelance designer landing a big retainer, or a sole trader who sells a business asset all risk the threshold without necessarily planning for it.

The unexpected 60% trap above £100,000

At £100,000, something stranger happens. HMRC begins withdrawing the Personal Allowance at £1 for every £2 of income above that level. By £125,140, the full £12,570 allowance has gone. On the £25,140 between £100,000 and £125,140 you effectively pay 40% Income Tax plus lose tax relief worth 40%, producing a marginal rate of 60%. Any income in that range is among the most expensively taxed in the entire UK system.

Tax Codes and the Higher Rate: Where Errors Creep In

If you are employed, your employer deducts tax via PAYE using your tax code. Most codes assume a standard pattern of income throughout the year. If you receive a large bonus in a single month, HMRC's system can over-collect tax mid-year (because it projects you will earn that amount every month) and then issue a refund after the year-end Self Assessment. Conversely, if you have a second income HMRC does not know about, you can underpay and face a January bill.

One specific code to be aware of: if HMRC instructs your employer to collect tax on a second job at 40% from the first pound, they apply the D0 tax code, which taxes all income from that employment at the higher rate with no Personal Allowance. This is correct when your main employment already uses up your basic rate band, but it is worth confirming the code is applied to the right job.

Reducing Income That Falls Into the 40% Band

Legal, straightforward planning can pull income back below or closer to £50,270:

Pension contributions: Every pound paid into a registered pension reduces your adjusted net income. A higher rate taxpayer effectively gets 40% relief, meaning a £1,000 contribution costs only £600 out of pocket after the tax saving is claimed via Self Assessment.

Gift Aid donations: Charities reclaim basic rate relief at source, but higher rate taxpayers can claim the additional 20% through their tax return, reducing their higher rate liability.

Salary sacrifice schemes: If you are employed, ask whether your employer offers salary sacrifice for pension, cycle-to-work or electric vehicles. Sacrifice reduces your gross pay, potentially keeping you below the threshold entirely.

Timing self-employed income: Sole traders on cash basis can legitimately influence which tax year income falls in by timing invoices near the year-end (5 April). Accelerating expenses into a high-income year achieves the same result.
