Tax calculators for 2026/27

What each calculator covers

• Income tax and take-home pay

  Works out income tax, National Insurance, student loan repayments and the Child Benefit charge on salary, self-employed profit, dividends, savings and rental profit. It shows what you keep, the tax on your next £100, and the effect of pension payments and salary sacrifice.

• Capital gains tax

  Works out tax on gains from shares, property and other assets, using your income to see how much of the basic-rate band is left, with losses, the annual exempt amount and Business Asset Disposal Relief.

• Corporation tax

  Works out a company's corporation tax, applying the small profits rate, the main rate and marginal relief, with adjustments for short accounting periods and associated companies.

• Salary, dividends or sole trader

  Compares what an owner-manager keeps from company profits at different salary levels, finds the best mix, and compares it with trading as a sole trader.

• Cost of employing someone

  Shows the full cost of a salary to the business, including employer National Insurance, the Employment Allowance and pension, and what the employee takes home.

• VAT

  Adds VAT to a price or takes it out of one at the standard, reduced or zero rate, and shows how close your turnover is to the registration threshold.

• Mileage claims

  Works out the approved mileage amount for business journeys in your own car, van, motorcycle or bicycle.

How these calculators work

• They use the 2026/27 rates for England, Wales and Northern Ireland. Scotland has different income tax bands, so Scottish taxpayers should speak to us.
• They give estimates from the figures you enter. They do not replace a tax return, and they do not cover every relief, benefit in kind or special case.
• Nothing you type leaves your device. The page does not store your figures.
• Rates come from GOV.UK and are the same figures printed in the tax tables above.

This is general information, not advice on your circumstances. Tax rules change and the right answer often depends on facts a calculator cannot see. Please speak to us before acting.
