Tax-Calculator (jdspr)
React calculator for Belgian self-employed: INASTI contributions, income tax (IPP), VAT and expenses.
What it does
Browser calculator for Belgian self-employed people: from revenue it works out professional expenses (flat-rate or actual), INASTI contributions, personal income tax (IPP) with municipal tax and the VAT balance, on 2024 rates. Runs locally with npm run dev on Vite and React. No README and no licence file; the method and rates are described only in CLAUDE.md, which says to update the rates yearly.
Licence unknown: we found no licence we could recognise. Check with the maintainers before you reuse the code.
Where it fits on the map
Not on the map: for individual taxpayers.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
