About

Making tax calculations clearer, verifiable and useful.

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

How we work

1

Traceable sources

Regulatory parameters are linked to official sources and an identifiable tax year.

2

Tested calculations

The engine, annual parameters and editorial content stay separate so each change can be checked.

3

Explicit limitations

Results are documented estimates, not tax advice tailored to an individual situation.

What is available today

Luxembourg is the first covered market, with a French foundation designed to expand to more languages and jurisdictions.

  • Simple and advanced modes with monthly and annual results
  • Five guides covering salaries, contributions, tax and payslips
