Taiwan Tax Calculator (2026) — Add or Reverse Tax
Taiwan charges a 5% VAT, a 20% corporate tax rate, and a 40% top personal income tax rate.
How to use this calculator:
- Purchase mode — add VAT to a pre-tax price, or reverse a tax-included total to find the pre-tax price and exact tax paid.
- Profit / salary modes — enter an amount to see the corporate tax owed or a ceiling estimate of personal tax at the top marginal rate.

Why Reverse Tax Calculation Matters
Receipts and invoices usually show only the tax-included total, so separating revenue from tax collected — for bookkeeping or cross-border comparisons — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why selecting "Reverse" in the purchase-mode calculator above handles it exactly.
History & Context
Taiwan's business tax system runs two parallel tracks — a Value Added Tax (currently 5%) for most businesses and a separate Gross Business Receipts Tax for specific sectors like banking and insurance that don't fit the standard VAT input-credit model.
Taiwan Semiconductor Manufacturing Company (TSMC) alone paid over NT$100 billion (roughly $3.4 billion) in corporate income tax in 2024 — about 15.9% of Taiwan's entire corporate income tax collection from a single company — illustrating how concentrated Taiwan's corporate tax base is around its dominant semiconductor industry.
Business Use Case
A small Taiwanese business with taxable income under NT$120,000 pays no corporate income tax at all, while a company like TSMC above that threshold pays the standard 20% rate on a vastly larger base — Taiwan's flat 20% rate applies uniformly once the small-business exemption threshold is crossed.
Real-World Examples
VAT on a purchase
A NT$1,000.00 purchase in Taiwan at 5%:
- Tax: NT$1,000.00 × 5% = NT$50.00
- Total: NT$1,050.00
Corporate tax on profit
NT$1,000.00 in company profit in Taiwan at 20%:
- Tax: NT$1,000.00 × 20% = NT$200.00
- After-tax profit: NT$800.00
Extracting VAT from a receipt total (reverse)
A receipt shows a NT$1,499.00 tax-included total in Taiwan at 5%:
- Pre-tax price: NT$1,499.00 ÷ (1 + 5%) = NT$1,427.62
- VAT: NT$1,499.00 − NT$1,427.62 = NT$71.38
