UK Income Tax 2026/27: Rates, Brackets & Free Calculator

On this page

UK income tax looks simple until your first payslip arrives and the numbers do not match what you expected. The confusion usually comes from one misunderstanding: you do not pay your top rate on your whole income — only on the slice of it that falls inside each band. Once that clicks, the whole system makes sense.

This guide covers the 2026/27 UK income tax bands, the personal allowance (and its sneaky taper), how Scotland differs, and how to estimate your own bill in seconds.

The 2026/27 UK income tax bands

For England, Wales, and Northern Ireland, the 2026/27 tax year (6 April 2026 – 5 April 2027) looks like this:

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%

Every threshold is currently frozen until April 2031. That freeze matters: as wages rise with inflation but bands stay put, more people drift into higher bands each year without feeling richer — economists call this fiscal drag.

A worked example: earn £60,000 and you do not pay 40% on £60,000. You pay 0% on the first £12,570, 20% on the next £37,700 (£12,571–£50,270), and 40% only on the final £9,730 above £50,270. Total income tax: about £11,432 — an effective rate of roughly 19%, not 40%.

The personal allowance and the £100k trap

The personal allowance (£12,570) is the amount you earn tax-free. But it has a tripwire: once your adjusted net income passes £100,000, the allowance shrinks by £1 for every £2 you earn above it, vanishing entirely at £125,140.

This creates the famous 60% effective rate between £100,000 and £125,140 — you pay 40% higher-rate tax plus lose tax-free allowance at the same time, equivalent to another 20%. It is the most expensive income stretch in the UK tax system, and exactly why pension contributions (which reduce adjusted net income) are so valuable in that range.

Scotland: different bands entirely

Scotland sets its own income tax bands, and they are more granular:

Band	Income	Rate
Personal allowance	Up to £12,570	0%
Starter	£12,571 – £16,537	19%
Basic	£16,538 – £29,526	20%
Intermediate	£29,527 – £43,662	21%
Higher	£43,663 – £75,000	42%
Advanced	£75,001 – £125,140	45%
Top	Over £125,140	48%

Which system applies depends on where your main home is, not where you work. Cross-border commuters should check their tax code starts with the right letter.

How to estimate your UK income tax (3 steps)

Enter your gross annual income into DollarWise’s free UK Income Tax Calculator — it applies the 2026/27 bands automatically.
Add pension contributions and Gift Aid if relevant — these reduce your taxable income and can pull you out of the personal-allowance taper zone.
Remember what is not included — National Insurance, student loan repayments, and Scottish rates (if applicable) are separate. The calculator estimates income tax only.

Beyond income tax: the full deduction picture

Your payslip shows more than income tax:

National Insurance — a separate payroll tax with its own thresholds and rates. It is often the bigger surprise for new earners.
Student loan repayments — 9% of earnings above the repayment threshold for Plan 2 loans, deducted like a tax but technically a loan repayment.
Pension contributions — usually deducted before tax is calculated, which is why they are the single best lever for reducing your bill.

A £50,000 salary can easily lose 30%+ to the combination of these. Always budget on take-home pay, never gross.

Common UK tax mistakes

Wrong tax code. An emergency or outdated tax code (check your payslip) can over- or under-deduct for months. HMRC’s personal tax account shows your current code.
Ignoring the £100k taper. Earning £100,001 can cost you far more than £1 in extra tax. If you are near the line, pension contributions or Gift Aid donations can pull you back under.
Forgetting savings and dividend allowances. The first £1,000 of savings interest (£500 for higher-rate taxpayers) and £500 of dividends are tax-free on top of the personal allowance.
Not filing when required. Employees usually need no tax return, but side income over £1,000, rental income, or high-earner child benefit charges can trigger Self Assessment.

Estimates only — verify against HMRC before making financial decisions. Tax rules change at Budgets.
