Estimates only

All results produced by this calculator are estimates based on the figures you enter and HMRC-published rates for the selected tax year. They are for planning and comparison purposes only.

Results do not constitute a formal tax calculation, Self Assessment return or statement of tax liability. Your actual tax position will depend on your full personal and business circumstances, including income from other sources, allowable expenses, filing elections and other factors not modelled here.

Not financial or tax advice

Nothing on this site constitutes financial, tax, legal or accounting advice. You should not rely on these estimates when making significant financial decisions, submitting a tax return or planning business structures.

For formal tax calculations, Self Assessment filing, or any decision with significant financial consequences, consult a qualified accountant, tax adviser or use HMRC's official Self Assessment service.

No guarantee of accuracy

Whilst every effort is made to keep rates and thresholds accurate and up to date, we cannot guarantee that all information is current at all times. Tax rules change and individual circumstances vary. Source links to GOV.UK are provided so you can verify the current position independently.

Limitation of liability

To the maximum extent permitted by law, we accept no liability for any loss or damage arising from your use of this website or reliance on its estimates.
