React calculator for Taiwan individual income tax, with three filing methods for married couples.
What it does
Browser calculator for Taiwan's individual income tax for the 2026 filing year: enter salary, other income, marital status, dependants and deductions to see the tax due, effective rate, bracket and each step, and compare the three filing methods for married couples. A React app on GitHub Pages, no account or key. For reference only; official amounts follow the Ministry of Finance.
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.
