UK income tax ranges from 0% to 45% depending on your income band. The UK uses a progressive tax system, meaning you don’t pay a single flat rate on your entire salary — instead, different portions of your income are taxed at different rates as they pass through each band. This is one of the most commonly misunderstood aspects of the UK tax system, and it means moving into a “higher tax bracket” doesn’t suddenly make all your income taxed at that higher rate.
This guide breaks down exactly how much tax you’ll pay at every salary level, how the personal allowance taper works, what Scottish taxpayers pay differently, and practical strategies to reduce your tax bill.
UK Income Tax Rates 2026/27
The table below shows the four income tax bands for England, Wales, and Northern Ireland. Scotland has its own rates (covered below).
| Tax Band | Taxable Income | Rate |
|---|---|---|
| Personal Allowance | £0 - £12,570 | 0% |
| Basic Rate | £12,571 - £50,270 | 20% |
| Higher Rate | £50,271 - £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
Note: Personal Allowance reduces by £1 for every £2 earned over £100,000.
The Personal Allowance (£12,570) has been frozen since 2021 and is expected to remain frozen until at least 2028. Because the threshold hasn’t risen with inflation, more workers are being pulled into higher tax bands each year — a process known as “fiscal drag” or “stealth taxation.” Someone earning £50,000 today pays significantly more tax in real terms than someone earning that amount in 2021.
Tax Calculation Examples
The best way to understand how progressive taxation works is to see it in action. In each example below, notice how income is “sliced” through the bands — the first £12,570 is always tax-free, the next portion is taxed at 20%, and so on.
£30,000 Salary
| Band | Taxable Amount | Rate | Tax |
|---|---|---|---|
| Personal Allowance | £12,570 | 0% | £0 |
| Basic Rate | £17,430 | 20% | £3,486 |
| Total Tax | £3,486 |
£60,000 Salary
| Band | Taxable Amount | Rate | Tax |
|---|---|---|---|
| Personal Allowance | £12,570 | 0% | £0 |
| Basic Rate | £37,700 | 20% | £7,540 |
| Higher Rate | £9,730 | 40% | £3,892 |
| Total Tax | £11,432 |
£100,000 Salary
| Band | Taxable Amount | Rate | Tax |
|---|---|---|---|
| Personal Allowance | £12,570 | 0% | £0 |
| Basic Rate | £37,700 | 20% | £7,540 |
| Higher Rate | £49,730 | 40% | £19,892 |
| Total Tax | £27,432 |
Personal Allowance Reduction
This is the single most important tax trap in the UK system. Once your income exceeds £100,000, your Personal Allowance starts disappearing — you lose £1 of allowance for every £2 you earn above £100,000. The result is a hidden 60% marginal tax rate in the £100,000–£125,140 range that catches many people off guard.
| Income | Personal Allowance | Effective Rate |
|---|---|---|
| £100,000 | £12,570 | 27.4% |
| £110,000 | £7,570 | 33.0% |
| £120,000 | £2,570 | 37.5% |
| £125,140+ | £0 | 40% |
The £100,000–£125,140 range has an effective 60% marginal tax rate due to allowance tapering. For every additional £1 you earn in this band, you lose 50p of Personal Allowance (which would have been tax-free), plus you pay 40% tax on the £1 itself. The combined effect is 60p in tax on every additional £1 earned. This is why many higher earners make pension contributions to keep their income below £100,000 — it’s one of the most effective tax planning strategies available.
Scottish Income Tax Rates
If you live in Scotland, you pay Scottish Income Tax rates set by the Scottish Parliament instead of the UK-wide rates above. Scotland has introduced a more graduated system with six bands instead of three, including a starter rate (19%) and an advanced rate (45%). The result is that lower earners in Scotland pay slightly less tax than their English counterparts, while higher earners pay noticeably more — particularly above £75,000 where Scotland’s 45% advanced rate kicks in versus England’s 40%.
| Tax Band | Taxable Income | Rate |
|---|---|---|
| Personal Allowance | £0 - £12,570 | 0% |
| Starter Rate | £12,571 - £14,876 | 19% |
| Basic Rate | £14,877 - £26,561 | 20% |
| Intermediate Rate | £26,562 - £43,662 | 21% |
| Higher Rate | £43,663 - £75,000 | 42% |
| Advanced Rate | £75,001 - £125,140 | 45% |
| Top Rate | Over £125,140 | 48% |
Tax-Free Income
Beyond the Personal Allowance, there are several other sources of income that are completely tax-free. Making full use of these allowances is one of the easiest ways to reduce your overall tax bill — particularly the ISA allowance, which shelters investment growth and interest from tax indefinitely.
| Source | Limit |
|---|---|
| ISA interest/gains | Unlimited |
| Personal Savings Allowance | £1,000 (basic), £500 (higher) |
| Dividend Allowance | £500 |
| Rent-a-room relief | £7,500/year |
| Premium Bond prizes | Unlimited |
National Insurance (In Addition)
Income tax isn’t the only deduction from your pay. National Insurance (NI) is a separate tax that most employees pay on earnings above £12,570. While it’s technically a contribution toward the State Pension and other benefits, in practice it functions as an additional income tax. When planning your finances, you need to consider both taxes together to understand your true marginal rate.
| Earnings | Employee NI Rate |
|---|---|
| £0 - £12,570 | 0% |
| £12,571 - £50,270 | 8% |
| Over £50,270 | 2% |
Combined marginal rates (Income Tax + NI):
- Basic Rate band: 28%
- Higher Rate band: 42%
Take-Home Pay Examples
Here’s what you actually take home at various salary levels after both income tax and National Insurance. These figures assume a standard tax code (1257L), no student loan deductions, and no pension contributions — your take-home will be lower if you have either of those.
| Gross Salary | Income Tax | NI | Take-Home (Monthly) |
|---|---|---|---|
| £25,000 | £2,486 | £1,007 | £1,792 |
| £35,000 | £4,486 | £1,807 | £2,392 |
| £50,000 | £7,486 | £3,007 | £3,292 |
| £75,000 | £17,432 | £3,507 | £4,505 |
| £100,000 | £27,432 | £4,007 | £5,713 |
How to Reduce Your Tax Bill
There are several legitimate strategies to reduce the amount of income tax you pay. The most powerful is making pension contributions, which attract tax relief at your highest marginal rate. If you’re a higher-rate taxpayer contributing £10,000 to a pension, you effectively get £4,000 back in tax relief. For those in the £100,000–£125,140 trap, pension contributions are even more valuable because they restore your Personal Allowance.
| Strategy | Tax Saving |
|---|---|
| Pension contributions | Full marginal rate |
| Salary sacrifice | NI + income tax |
| Marriage Allowance | £252/year |
| Gift Aid donations | Reclaim tax paid |
| ISA investing | Tax-free growth |
Marriage Allowance
Marriage Allowance is a simple tax break that many eligible couples overlook. If one partner earns less than the Personal Allowance (£12,570) and the other is a basic rate taxpayer, the lower earner can transfer 10% of their unused allowance to their partner.
- Transfer £1,260 of your allowance
- Partner saves £252/year
- You can backdate 4 years (up to £1,260 total)
Payment Methods
How you pay income tax depends on how you earn your money. Most employees never need to think about it — PAYE (Pay As You Earn) handles everything automatically through your employer’s payroll. Self-employed workers must file a Self Assessment tax return and pay their own tax bill.
| Employment Type | How Tax is Collected |
|---|---|
| Employed (PAYE) | Automatic from pay |
| Self-employed | Self Assessment |
| Multiple jobs | Tax code allocation |
| Pension income | Usually PAYE |
Key Deadlines
If you’re required to file a Self Assessment tax return (self-employed, rental income, income over £100,000, or untaxed income), these are the dates you need to know. Missing the 31 January deadline results in an automatic £100 penalty, with further penalties accumulating the longer you delay.
| Deadline | Date |
|---|---|
| Tax year end | 5 April |
| Self Assessment registration | 5 October |
| Paper tax return | 31 October |
| Online tax return | 31 January |
| Tax payment due | 31 January |
Bottom Line
The UK’s progressive tax system means your effective tax rate is always lower than your marginal rate. Even someone earning £100,000 keeps over two-thirds of their gross salary after income tax and NI.
| Salary | Take-Home % | Effective Tax Rate |
|---|---|---|
| £25,000 | 86.0% | 14.0% |
| £50,000 | 79.0% | 21.0% |
| £75,000 | 72.1% | 27.9% |
| £100,000 | 68.6% | 31.4% |
Tips:
- Use your full pension allowance (reduces taxable income)
- Maximise ISA contributions (tax-free growth)
- Claim Marriage Allowance if eligible
- Salary sacrifice for additional NI savings
