Calculations use 2026 statutory rates pulled directly from each country's tax authority and cross-checked against PwC Tax Summaries. Primary sources include HMRC for the United Kingdom, Belastingdienst for the Netherlands, gesetze-im-internet.de for Germany, ZUS and Ministerstwo Finansów for Poland, the State Tax Service for Ukraine, Agenzia delle Entrate for Italy, and equivalent official publications for the remaining seven countries. Where brackets or thresholds update mid-year, the rates in force from 1 January 2026 are used.
Employee mode applies standard statutory income tax plus mandatory social contributions: pension, health, unemployment, and care insurance where applicable, each subject to its own cap or floor. Self-employed mode applies the country-specific simplified regime available to freelancers and contractors: JDG in Poland, Selbstständig and Freiberufler in Germany, self-employed Class 4 NIC in the UK, FOP group 3 in Ukraine, ZZP in the Netherlands, autónomo under RETA in Spain, IFICI (the successor to NHR) in Portugal, self-employed flat regime in Bulgaria, PFA in Romania, OSVČ with 60% expense paušál in Czech Republic, OÜ dividend distribution in Estonia, Micro-Entrepreneur BNC in France, and Forfettario in Italy.
Amounts are calculated internally in each country's native currency on an annual basis, then converted to the selected display currency using exchange rates from open.er-api.com refreshed hourly. Currency conversion affects display only; the underlying tax math is always performed in the native currency to preserve accuracy.
Estimates exclude regional and municipal surcharges, voluntary insurance top-ups, personal deductions beyond the standard personal allowance, dependent credits, and special tax treaties that may apply to specific expat situations. Cost of living, healthcare quality, public services, and other non-monetary factors are out of scope — this tool compares the tax burden component only.
