Tax Bracket Calculator

This UK tax bracket calculator estimates income tax, marginal rate, and effective tax rate from the income figure you enter.

Tax brackets are progressive. That means moving into a higher band does not usually make all your income taxable at the higher rate; only the income inside that band is taxed at that rate.

Use it for planning, comparison, and general understanding. Actual tax can vary because of tax codes, allowances, benefits, pension contributions, Scottish rates, student loans, and other personal circumstances.

If someone earns £55,000, not all of that income is taxed at the higher-rate band. The lower bands are filled first, then only the portion above the relevant threshold is taxed at the higher marginal rate.

This is why a pay rise can still leave you better off even if part of the rise falls into a higher band. The calculator helps separate the total tax bill from the tax rate on the next pound earned.

Your marginal rate is useful when judging bonuses, overtime, side income, or pension contributions. It estimates how much of the next pound may be lost to income tax before other deductions.

Your effective rate is better for understanding the overall tax burden. Two people can share the same marginal band but have different effective rates depending on how much of their income sits in each band.

Use this calculator when the question is income tax banding: total income tax, marginal rate, effective rate, and after-tax income from the income and allowance values you enter.

The component has a simple taxable-income mode and a gross-income-with-allowance mode. It does not include National Insurance, student loans, Scottish bands, benefits, or full payroll rules.

Use uk income tax calculator when you need the richer UK income tax page with region and optional NI estimate.

Use salary after tax calculator when you want a take-home pay estimate rather than a band-focused income tax view.

Label saved scenarios with whether you entered taxable income or gross income, because those two modes answer different questions.

Treating the marginal rate as if it applies to all income. Progressive bands tax only the slice inside each band.

Entering gross income in taxable-income mode and then also using a personal allowance elsewhere, which can double-count the allowance.

Using this page for Scottish income tax. The simple tax bracket component uses the rest-of-UK band structure; use the UK income tax page for the Scotland selector.

Quoting income tax alone as total employment tax. National Insurance and payroll deductions are separate.

Applying earned-income bands to dividends, savings interest, or capital gains without checking their separate allowances and rates.

Example: enter £50,000 as taxable income to estimate income tax, effective rate, marginal rate, and after-tax income under the simple UK band model.

Switch to gross-income mode only when you want the calculator to subtract a personal allowance before applying the bands.

Change one input at a time — income, input mode, or personal allowance — so you can see whether the band, taxable amount, or allowance is driving the result.

Use the result to understand tax bands, then move to the salary after tax calculator when you need monthly take-home pay.

Use salary after tax for employee take-home pay including simplified NI, pension, and student loan deductions.

Use uk income tax for region-aware income tax estimates and a band breakdown.

Use capital gains tax separately because CGT uses disposal proceeds, cost basis, allowance, asset type, and CGT rates rather than salary bands.

Do not use this page as a generic tax return calculator; it is a focused income-tax-band tool.

Check whether you entered taxable income or gross income. The wrong mode can shift the result by the personal allowance amount.

Check whether your personal allowance is standard, tapered, or adjusted by your tax code before using the result in a serious decision.

Check whether Scotland, dividends, savings income, pension relief, or student loans matter. Those are better handled by specialist pages or official guidance.

Rerun this tax bracket calculator when taxable income, personal allowance, or the relevant UK band structure changes.

Recheck before bonuses, overtime, or pension contribution decisions if you are using marginal rate to understand the next pound of income.

If this estimate differs from HMRC software, a payslip, or the UK income tax calculator, first check whether each tool is using the same income, allowance, region, and deduction scope.
