To find out what tax band you’re in, compare your total taxable income for the tax year (6 April to 5 April) against the thresholds for where you live. In England, Wales, and Northern Ireland there are three rates above the tax-free Personal Allowance; in Scotland there are six. The band you’re “in” is the one that applies to your highest pound of income, and it sets your marginal rate along with several other things: how much savings interest you can earn tax-free, what rate your dividends are taxed at, whether you owe the High Income Child Benefit Charge, and how much relief your pension contributions attract.
The Bands in England, Wales, and Northern Ireland
The thresholds have been frozen since 2021 and stay the same for 2026/27. Your first £12,570 is your Personal Allowance and carries no tax. Above that:
- Basic rate, 20%: £12,571 to £50,270
- Higher rate, 40%: £50,271 to £125,140
- Additional rate, 45%: above £125,140
If you earn £55,000, you are a higher-rate taxpayer even though most of your income sits in the basic band or the allowance. The label follows your top pound, not your average.1GOV.UK. Income Tax Rates and Personal Allowances
The Bands in Scotland
If you live in Scotland, rates are set by the Scottish Parliament. The Personal Allowance is still £12,570, but above it the income is split into six bands for 2026/27:
- Starter rate, 19%: £12,571 to £16,537
- Scottish basic rate, 20%: £16,538 to £29,526
- Intermediate rate, 21%: £29,527 to £43,662
- Higher rate, 42%: £43,663 to £75,000
- Advanced rate, 45%: £75,001 to £125,140
- Top rate, 48%: above £125,140
The higher and top-rate thresholds are frozen; the basic and intermediate thresholds rose by 7.4 percent for 2026/27. Scottish residency is based on where you live, not where you work, so someone commuting into England from a Scottish home pays Scottish rates. A salary of £50,000 pulls a Scottish resident into the higher rate (42 percent above £43,663), while the same salary elsewhere in the UK stays under the higher-rate threshold.2MyGov Scotland. Current Rates – 6 April 2026 to 5 April 2027
Which Income Counts
Your band is worked out from your total income across the tax year, not just your salary. That means:
- Gross employment pay including bonuses and commission, or self-employed profits after allowable expenses
- Rental income from property
- Savings interest outside an ISA
- Dividends outside an ISA
- Taxable benefits from your employer, such as a company car or private medical cover, reported on a P11D3GOV.UK. Expenses and Benefits for Employers – Reporting and Paying
From that total, deduct pension contributions and grossed-up Gift Aid donations. The result is your adjusted net income, and that is the figure HMRC lines up against the band thresholds and the £100,000 and £60,000 tapering points below.4GOV.UK. Personal Allowances – Adjusted Net Income
Moving Up a Band Doesn’t Retax Everything
One thing to get straight: crossing into a higher band never means all your income is suddenly taxed at the higher rate. Each rate only applies to the income that falls inside its band. The Personal Allowance stays tax-free, the basic-rate slice is taxed at 20 percent, and only the pounds above £50,270 get the 40 percent rate. A pay rise that nudges you across a threshold leaves you better off, not worse.
There is one place this breaks down, and it catches people out.
The 60% Effective Rate Between £100,000 and £125,140
If your adjusted net income goes above £100,000, your Personal Allowance shrinks by £1 for every £2 above the threshold. By £125,140 it is gone. On that slice of income you pay 40 percent tax and lose tax-free allowance at the same time, giving an effective rate of 60 percent. It’s the steepest marginal rate in the system, and unlike ordinary band boundaries, it genuinely does mean each extra pound in that range costs you more than a pound higher up.1GOV.UK. Income Tax Rates and Personal Allowances
Pension contributions and Gift Aid donations reduce adjusted net income, so someone earning £105,000 who pays £6,000 into a pension drops back to £99,000 and keeps the full allowance. Standard pension contributions are capped at £60,000 per year or 100 percent of earnings, whichever is lower.5GOV.UK. Pension Schemes Rates
What Your Band Changes Beyond Income Tax
Knowing your band matters because several other tax rules key off it directly.
Savings Interest
The Personal Savings Allowance depends entirely on your band. Basic-rate taxpayers can earn £1,000 of interest tax-free each year. Higher-rate taxpayers get £500. Additional-rate taxpayers get nothing. Interest inside an ISA is outside this system and stays tax-free at any income level.6GOV.UK. Tax on Savings Interest – How Much Tax You Pay
Dividends
Dividends have their own £500 tax-free allowance. Above that, the rate is set by your band: 10.75 percent for basic-rate taxpayers, 35.75 percent for higher-rate, and 39.35 percent for additional-rate, following changes from April 2026.
High Income Child Benefit Charge
If you or your partner claim Child Benefit and the higher earner has adjusted net income above £60,000, that person owes a tax charge that claws back part of the benefit. The charge rises with income and reaches 100 percent of the Child Benefit at £80,000. Because it uses adjusted net income, pension contributions and Gift Aid reduce it.7GOV.UK. Child Benefit Tax Calculator
Marriage Allowance
A married or civil-partnered couple where one earns below the Personal Allowance can transfer £1,260 of the unused allowance to the other, worth up to £252 a year. The receiving partner must be a basic-rate taxpayer in England, Wales, or Northern Ireland, or a starter, basic, or intermediate-rate taxpayer in Scotland. Higher-rate taxpayers don’t qualify.8GOV.UK. Marriage Allowance – How It Works
Checking What HMRC Thinks You Earn
Your tax code is the shorthand HMRC gives your employer or pension provider to work out how much tax-free income to apply. The standard code is 1257L, matching the £12,570 Personal Allowance. You’ll find your code on your payslip, your P60 at the end of the tax year, or your P45 if you’ve recently left a job.9GOV.UK. Understanding Your Employees Tax Codes
To see your current code, an estimate of your income tax for the year, and any recent adjustments, sign in to your personal tax account on GOV.UK.10GOV.UK. Personal Tax Account – Sign In or Set Up
Two codes are worth a closer look. A code with an M1 or W1 suffix is an emergency code, taxing you on a month-by-month or week-by-week basis without your full year’s allowances. It commonly appears when you start a job without a P45 or take a lump sum from a pension, and it usually leads to an overpayment that HMRC refunds once the code is corrected. A code starting with K means your deductions (for company benefits, state pension, or unpaid tax from earlier years) exceed your Personal Allowance, so instead of a tax-free amount, a figure is added to your taxable pay. The amount taken in any pay period is capped at half your pre-tax pay.11GOV.UK. Understanding Your Employees Tax Codes – What the Letters Mean
If the code looks wrong, or if your income has changed enough to push you into a different band, update your details through the personal tax account or contact HMRC directly. A wrong code doesn’t change what you owe in the end, but it can leave you overpaying month after month until it’s fixed.
