Disclaimer

Not financial, tax or legal advice

Nothing on this site is financial, tax, legal, or professional advice of any kind, and no figure produced by a calculator here should be treated as a recommendation to take or avoid any particular action. Using a calculator on this site does not create an adviser-client relationship, and no advice is given or implied about what you personally should do.

Every result is an estimate

Each calculator applies published HMRC and gov.scot rates and thresholds for the 2026/27 tax year to the numbers you enter, using the assumptions listed on that calculator’s own page (usually a single, stable salary with no other income, and no unusual personal circumstances). It cannot know about your employer’s specific scheme rules, other income you have, tax reliefs you’re entitled to, or anything HMRC holds on your tax code that differs from the standard assumptions. Real payroll figures can differ from an estimate here, sometimes by a meaningful amount, for reasons the calculator has no way to see.

Accuracy is not guaranteed

Reasonable care is taken to keep every rate, threshold, and calculation correct and up to date, and each calculator’s methodology and sources are published on its own page and on the About & methodology page. Even so, no guarantee is given that any result is complete, current, or free of error. Tax rules change, sometimes with little notice, and a calculator here may lag behind an announced change until it’s been reviewed and updated.

Not affiliated with HMRC or the UK Government

UK Calculators is an independent site. It is not affiliated with, endorsed by, or connected in any way to HMRC, gov.scot, or the UK Government, and is not an official government service. For your definitive tax position, use HMRC’s own services or speak to HMRC directly.

Before you rely on a result

• Check the figures against your own payslip, pension statement, or HMRC account where you can.
• For a decision that matters, such as changing your pension contributions or agreeing to a salary sacrifice scheme, speak to your employer’s payroll team or a regulated financial adviser first.
• Contact HMRC directly for anything specific to your own tax record or tax code.
