Income Tax Calculator

This UK income tax calculator estimates the Income Tax due on an annual income for the 2026/27 tax year, band by band, for England, Wales, Northern Ireland and Scotland.

It answers the question “how much income tax will I pay?” for earned income. It calculates Income Tax only: National Insurance, student loan repayments, pension deductions, dividend tax and tax on savings are deliberately excluded, and each has its own calculator.

Income Tax calculator inputs

Your gross income for the 2026/27 tax year.

Scotland sets its own Income Tax bands on earnings. Welsh rates currently match England and Northern Ireland.

Advanced: adjusted net income

Adjusted net income is used only to work out whether your Personal Allowance is reduced above £100,000. Most people should leave it equal to their income, and only change it if they know their adjusted net income differs because of allowable adjustments such as gift aid or personal pension contributions.

Reading your result

The headline figures are the Income Tax estimated for the whole tax year and the income you keep after that tax. Switch between annual, monthly and weekly to see the same annual calculation presented over a shorter period.

The effective rate is your total Income Tax divided by your income, so it is always lower than your top band rate. The marginal rate is the statutory rate that would apply to your next £1 of taxable income. Personal Allowance used shows the allowance left after any taper, and taxable income is what the bands are applied to.

  • The band table shows exactly how much income falls in each band and the tax charged there.
  • Scottish taxpayers see the Scottish starter, basic, intermediate, higher, advanced and top bands.

How UK Income Tax works

Most people can receive a Personal Allowance of £12,570 before paying Income Tax. Income above that allowance is taxable and is charged in slices: each band taxes only the part of your taxable income that falls inside it, which is why moving into a higher band never reduces your take-home pay.

In England, Wales and Northern Ireland the basic rate of 20% applies to the first £37,700 of taxable income. The 40% higher rate applies to taxable income from £37,701 to £125,140 — with a full allowance, the 40% tax threshold is reached at around £50,270 of income. The additional rate of 45% applies above £125,140 of taxable income.

Scotland sets its own rates and bands on earnings, with six bands from 19% to 48%. The Personal Allowance itself is a UK-wide figure, so a Scottish taxpayer receives the same allowance but pays Scottish rates on taxable income.

  • Personal Allowance = £12,570, reduced by £1 for every £2 of adjusted net income above £100,000.
  • Taxable income = income − the Personal Allowance actually available.
  • Income Tax = the sum of each band rate applied to the income falling in that band.

Worked examples

£35,000 salary in England

An employee living in England earns £35,000 with a full Personal Allowance.

  1. Taxable income is £35,000 − £12,570 = £22,430.
  2. All of it sits in the basic rate band, so tax is £22,430 × 20%.

Estimated Income Tax is £4,486, leaving £30,514 before other deductions.

£60,000 salary in Scotland

A Scottish taxpayer earns £60,000 with a full Personal Allowance.

  1. Taxable income is £47,430, spread across the starter, basic, intermediate and higher bands.
  2. The starter, basic and intermediate bands account for £6,320.09 of tax up to £31,092 of taxable income.
  3. The remaining £16,338 is taxed at the Scottish higher rate of 42%.

Estimated Income Tax is £13,182.05 for the year.

£110,000 income and the allowance taper

Someone in England has adjusted net income of £110,000.

  1. Income is £10,000 above £100,000, so the allowance is reduced by £5,000 to £7,570.
  2. Taxable income becomes £102,430: £37,700 at 20% and £64,730 at 40%.

Estimated Income Tax is £33,432, an effective rate of about 30.4%.

Assumptions

The result depends on the following. If any of them do not match your situation, treat the figure as indicative only.

  • Figures use the verified 2026/27 rates and thresholds in force from 6 April 2026 to 5 April 2027.
  • Income is non-savings, non-dividend income such as employment or self-employment profit.
  • The standard Personal Allowance of £12,570 applies, tapered above £100,000 of adjusted net income.
  • Adjusted net income equals your income unless you enter a different figure in the advanced option.
  • Income Tax only: National Insurance, student loan repayments, pension contributions, dividend tax and savings tax are not included.

What this calculator does not do

  • It does not interpret a PAYE tax code, apply cumulative in-year adjustments or model an individual payslip.
  • Marriage Allowance, Blind Person’s Allowance, the savings and dividend allowances, the starting rate for savings, and reliefs such as pension or charitable adjustments are not applied automatically.
  • Benefits in kind, taxable state benefits, rental profit rules, multiple employments and underpayments collected through a tax code can all change the actual liability.
  • The marginal rate reported is the statutory band rate. The effective 60% cost of losing Personal Allowance between £100,000 and £125,140 is explained but is not presented as a tax band, because no such statutory band exists.

Methodology and 2026/27 rate basis

All figures come from a single versioned rate set, income-tax-2026-27, reviewed against the GOV.UK sources listed below on 20 September 2026. Nothing is scraped at runtime and no rate is hard-coded inside the interface.

The engine is pure TypeScript and runs entirely in your browser. It computes the available Personal Allowance, derives taxable income, then applies each band in order, keeping full precision internally and rounding only when a figure is displayed. Unit tests check published boundaries including £12,570, £50,270, £125,140 and the Scottish band edges.

Income Tax bands 2026/27 — England, Wales and Northern Ireland

These rates apply to taxable income, meaning income after the Personal Allowance has been deducted.

  • Basic rate 20% — first £37,700 of taxable income.
  • Higher rate 40% — taxable income from £37,701 to £125,140.
  • Additional rate 45% — taxable income above £125,140.

Scottish Income Tax bands 2026/27

A Scottish income tax calculation uses six bands on earned income. National Insurance remains UK-wide and is not affected by where you live.

  • Starter rate 19% — first £3,967 of taxable income.
  • Basic rate 20% — £3,968 to £16,956.
  • Intermediate rate 21% — £16,957 to £31,092.
  • Higher rate 42% — £31,093 to £62,430.
  • Advanced rate 45% — £62,431 to £125,140.
  • Top rate 48% — above £125,140.

The £100,000 Personal Allowance taper

Once adjusted net income passes £100,000, the Personal Allowance falls by £1 for every £2 of income above that point, and disappears entirely at £125,140. Losing allowance means extra income is taxed twice over in effect: once at the statutory band rate, and again because previously tax-free income becomes taxable.

In England, Wales and Northern Ireland this produces a well-known effective rate of about 60% on income between £100,000 and £125,140, even though the statutory band rate remains 40%. Adjusted net income can be reduced by allowable items such as personal pension contributions and gift aid donations, which is why the calculator lets you enter it separately.

Frequently asked questions

How much Income Tax will I pay on my salary?

Enter your annual income and where you live, and the calculator shows the Income Tax estimated for the 2026/27 tax year, band by band, plus your income after Income Tax. Remember that a payslip also has National Insurance and possibly pension and student loan deductions.

What are the Income Tax bands for 2026/27?

In England, Wales and Northern Ireland: 20% on the first £37,700 of taxable income, 40% from £37,701 to £125,140, and 45% above that. Scotland has six bands from 19% to 48%.

When does the 40% tax threshold start?

The higher rate applies to taxable income above £37,700. With the full £12,570 Personal Allowance, that equates to income of about £50,270. If your allowance is reduced, the threshold in terms of gross income arrives sooner.

Does this include National Insurance?

No. This is an Income Tax calculator only. National Insurance is a separate charge with its own thresholds — use the National Insurance or take-home pay calculators for a full payslip view.

Why does my Personal Allowance disappear above £100,000?

The allowance is reduced by £1 for every £2 of adjusted net income above £100,000 and reaches zero at £125,140. The calculator applies this automatically and flags when you are inside that range.

Are Scottish Income Tax rates different?

Yes. Scotland sets its own rates and bands on non-savings, non-dividend income. Choose Scotland and the breakdown switches to the Scottish bands. Savings and dividend income remain taxed at UK-wide rates.

Do Wales and Northern Ireland have their own rates?

Northern Ireland uses the UK rates. Wales can set Welsh rates of Income Tax, and for 2026/27 they are set at the same level as England and Northern Ireland, so the result is identical.

Why is my actual tax bill different?

Your tax code, savings and dividend income, benefits in kind, Marriage Allowance, Blind Person’s Allowance, reliefs, multiple income sources and in-year adjustments can all change the outcome. This is a general estimate, not tax advice.
