What is this calculator for?

Use it to estimate a Taiwan resident household’s taxable net income and progressive comprehensive-income tax under a simplified filing scenario. The 2026 filing covers 2025 income; official 2026-income amounts have also been announced for the 2027 filing season.

Why can the filed result differ?

Eligibility for dependents, itemized deductions, the basic-living-expense difference, special deductions, dividend taxation, AMT, and other rules can materially change the result. This tool intentionally asks you to enter eligible deductions rather than pretending to decide eligibility.
