Tax Calculators Telford • UK Tax Estimates • Personal, Property and Business Tax
Tax Calculators for Individuals, Landlords and Businesses
Use our UK tax calculators to estimate common tax figures before filing a return, reviewing a property position, checking company tax, planning dividends, preparing payroll or dealing with HMRC.
These calculators are designed for practical estimates. They should not be treated as final tax advice where the position involves property ownership, foreign income, company extraction, HMRC penalties, residence, earlier-year errors or incomplete records.
Direct answer
Which tax calculator should you use?
The right calculator depends on the tax question. If you are estimating tax on employment, pension income, dividends or mixed income, start with the Income Tax, Dividend Tax or Self Assessment calculator.
If you are a landlord or selling a property, use the rental profit, mortgage interest, non-resident landlord or Capital Gains Tax calculator. If you run a company, use the Corporation Tax, salary versus dividend, VAT or payroll calculator.
