On £75,000 of income in United Kingdom (2026/27 tax year), this estimates about £20,943 in tax (Income tax + National Insurance) — an effective rate of 27.92%, even though your marginal rate is 40%. The Personal Allowance and rate bands are set by HM Treasury and can change at each Budget or Autumn Statement. Thresholds are currently frozen through at least 2027/28, but that policy could change. Income tax + employee National Insurance. Does NOT include student loan repayments or any reliefs beyond the standard Personal Allowance. Covers England, Wales, and Northern Ireland only — NOT Scotland, which sets its own income tax bands and rates. Class 1 employee National Insurance applies to gross income directly (NOT to taxable income after the Personal Allowance) — NI has its own Primary Threshold, separate from the tax-free Personal Allowance, even though both happen to be £12,570 this tax year. This is an educational estimate, not tax advice or a substitute for a qualified accountant.

Progressive tax systems apply higher rates only to the income within each bracket, not your entire income at the top rate. This calculator uses real, sourced tax rules for each supported country to show exactly how that adds up — see the tax data source note on this page for exactly where the figures come from.
Effective rate vs. marginal rate
Your marginal rate is what you pay on your last dollar earned. Your effective rate — what actually matters for 'how much of my income goes to tax' — is always lower, because earlier income was taxed at lower bracket rates first.
What this doesn't include
This covers income tax only. Payroll-style taxes (US FICA, Canadian CPP/EI, UK National Insurance), state/provincial variations beyond what's noted, and personal credits or deductions beyond the standard ones aren't included — see this country's specific disclaimer above.
