Calculators and checkers
Every interactive tool on the site in one place: tax calculators, eligibility checks, calendars and route finders for Luxembourg, the Netherlands, Belgium and EU rules.
What the tools do
Each tool sits inside a page that explains the rules behind it. Calculators turn your figures into an estimate: tax on a profit, a net salary, withholding on a dividend, the cost of an employee. Checkers ask a few questions and return the rules that apply, the route that usually fits and the red flags to clear first.
They run in your browser and store nothing. Figures use the 2026 rates in force, and 2027 where the law is enacted or a proposal is clearly marked. Each tool states its own assumptions next to the result.
