Traceable sources
Regulatory parameters are linked to official sources and an identifiable tax year.
About
GlobalFiscalLab builds calculators and guides that explain their assumptions, keep rules separate from their sources and state their limitations clearly.
Roadmap updated on 21 August 2026
Regulatory parameters are linked to official sources and an identifiable tax year.
The engine, annual parameters and editorial content stay separate so each change can be checked.
Results are documented estimates, not tax advice tailored to an individual situation.
Luxembourg is the first covered market, with a French foundation designed to expand to more languages and jurisdictions.
Future updates
Priorities may change when official rules evolve or user feedback identifies a more important need.
Continuous improvement of explanations, reference cases and checks around the existing calculator.
Assessing net-to-gross, employer cost, bonuses and additional salary months before development.
Calculator, country page and five guides available in English with the same official sources.
German publication after complete translation and review of administrative and tax terminology.
Potential expansion to other jurisdictions when the required sources and tests can be maintained sustainably.
A feature is only marked as available after its sources, assumptions and tests have been reviewed.
GlobalFiscalLab does not replace an authority or qualified professional. Contact forms are for questions, corrections and partnerships; do not include payslips, declarations, identification numbers or other sensitive data.
