How it works

The United Kingdom edition of the income-tax estimator. It applies the England, Wales and Northern Ireland income-tax bands to the annual income you enter and returns the tax due, what is left, and your effective and marginal rates. The bands are labelled for the 2025 tax year in this build and are illustrative main rates only.

The personal allowance is encoded as a 0% band, so the schedule runs: 0% on the first £12,570, 20% (basic rate) from £12,570 to £50,270, 40% (higher rate) from £50,270 to £125,140, and 45% (additional rate) above that. Tax is then the sum of each slice × its band rate. Your marginal rate is the band your last pound falls in; your effective rate is total tax ÷ total income, and it is always lower because the earlier slices were taxed less.

Worked example at £60,000. The first £12,570 is covered by the allowance and taxed at 0%; the next £37,700 at 20% = £7,540; the remaining £9,730 at 40% = £3,892. Total income tax £11,432, leaving £48,568, an effective rate of 19.05% against a marginal rate of 40%. Being a higher-rate taxpayer clearly does not mean paying 40% on everything — here it is 40% on under a sixth of the income.

Three UK-specific caveats. National Insurance is a separate deduction from income tax and is not modelled, so your payslip will show less than £48,568 spread across the year. Scotland sets its own income tax bands, with more of them and different thresholds, so a Scottish taxpayer should not rely on this result. And most employees pay through PAYE, where HMRC collects tax month by month against a tax code — meaning your code, not this calculator, determines what actually comes out of each pay packet.

The engine also taxes exactly the number you type and applies nothing else: no adjustment of the allowance at higher incomes, no pension relief, no Gift Aid, no marriage allowance, no dividend or savings allowances, and no separate treatment of dividend income or capital gains. VAT is irrelevant here — it is a consumption tax already included in the shelf prices you pay at 20% standard rate. These are estimates for planning; check anything that matters with HMRC or a qualified adviser.

Frequently asked questions

Does this include National Insurance?
No. National Insurance is a separate charge from income tax with its own thresholds, and it is not modelled here, so your real take-home pay is lower than the figure shown. Treat the result as income tax only.
Does it work for Scottish taxpayers?
Not accurately. Scotland sets its own income tax bands and rates, with more bands and different thresholds than England, Wales and Northern Ireland. The schedule loaded here is the rest-of-UK one, so a Scottish taxpayer will get the wrong answer.
How is the personal allowance handled?
As a 0% band covering the first £12,570 of income, which is why tax only begins above that. The engine does not model any reduction of the allowance at higher incomes, so estimates for large incomes will be understated.
Why is my effective rate so much lower than my 40% band?
Because only the slice above £50,270 is taxed at 40%. At £60,000 the tax is £11,432 — an effective rate of 19.05% — since the first £12,570 is untaxed and the next £37,700 is taxed at 20%.
Will my payslip match this?
Not exactly. Employees are taxed through PAYE against a tax code that reflects your allowances, benefits in kind and any adjustments from previous years, and it is applied period by period rather than annually. National Insurance and pension contributions come off too.
What about pension contributions and dividends?
Neither is modelled. Pension relief, Gift Aid and the marriage allowance all change the tax due, and dividends and savings income have their own allowances and rates. This tool applies the four main bands to the single figure you enter and nothing more.
Is this an official HMRC calculation?
No — it is a planning estimate using illustrative bands for the labelled year. Use the HMRC calculators or speak to a qualified adviser before relying on the number.
