Sourced directly from tax authorities
Every rate, band, threshold, and credit is taken from the official publications of each country's revenue authority — not copied from other calculators. Budget changes are applied on the day they become effective.
Full breakdown, not just a number
You see exactly how your tax is computed: each band, each credit, each NI or social insurance class. The full breakdown tab shows every step. The payslip tab shows it the way your employer does.
All edge cases covered
Personal Allowance taper, married tax credits, pension age bands, student loan plan routing, self-employed NI classes, Scottish income tax bands — the details that matter for real people in real situations.
What is an income tax calculator?
An income tax calculator takes your gross salary or self-employment income and works out exactly how much you keep after all taxes — income tax, social insurance, and any other statutory deductions — are applied. Unlike a simple percentage estimate, a proper calculator applies the correct progressive rate schedule for your country, accounts for personal allowances or credits, handles pension relief, and shows breakdowns by pay period.
Tax systems vary enormously by country. Ireland uses a two-rate system (20%/40%) combined with a Universal Social Charge and PRSI, with tax credits reducing liability directly. The UK uses three rates (20%/40%/45%) with a Personal Allowance that phases out above £100,000, plus National Insurance as a separate deduction. Scotland has its own six-rate income tax schedule. A single calculator cannot accurately serve all of these — which is why we build dedicated, country-specific tools.
