UK tax calculation tools
Tax calculators for individuals, landlords and businesses
These calculators are designed to give a quick estimate of common UK tax figures. They are useful if you want to understand the tax effect of income, rental profit, dividends, capital gains, company profits, VAT or payroll before speaking to an accountant.
The calculators should not be treated as final tax advice. Tax depends on the tax year, allowances, reliefs, residence position, income sources, ownership structure and HMRC filing rules. If you are filing a tax return or responding to HMRC, the calculation should be reviewed properly.

- Tax rates and allowances depend on the tax year
