How these are maintained

Every tool states the figures it uses and the date they were last checked. Tax parameters move at least once a year — with each national budget — so anything showing a stale date should be treated as stale. Where a number is still provisional, such as the Dutch box 3 deemed return on savings for 2026, the page says so rather than presenting it as settled.

These calculators are for comparison and planning. They assume a single person with no dependents on a standard employment contract, and they are not a substitute for payroll software or advice from a qualified tax adviser in your country.
