Methodology

How we calculate

Every calculator states the tax year and the country whose rules it uses. Salary and savings tax rules are built in for 11 countries for 2026; investing and freelance rules for Germany, the Netherlands and Ireland. More countries follow as we verify them. Results are estimates for planning, not tax advice.

Rules last checked: 20 October 2026.
