Taiwan Comprehensive Income Tax (綜合所得稅): Rates and Residency
Taiwan's Comprehensive Income Tax (CIT — 綜合所得稅 — administered by the Ministry of Finance via National Taxation Bureau) uses a progressive system for residents. 2026 rates (TWD brackets): 5% (up to TWD 560,000), 12% (TWD 560,001–1,260,000), 20% (TWD 1,260,001–2,520,000), 30% (TWD 2,520,001–4,720,000), 40% (above TWD 4,720,000). Note: brackets are adjusted periodically — verify at etax.nat.gov.tw. Standard deduction (標準扣除額): TWD 124,000 per person (2026); dependent deductions available. Tax residency: a person is a Taiwan income tax resident if they stay in Taiwan for 183+ days in the taxable year (January–December). Non-resident treatment: those present fewer than 90 days: 18% flat withholding on Taiwan-source income (no deductions). Those present 91–182 days: 18% flat withholding (same — but note the MOF may apply different rules for specific income types). After 183 days: resident rates apply with full deduction entitlements. Year of departure: if you leave mid-year having already been resident (183+ days), you file as a resident for that full year. If you leave before reaching 183 days in the departure year: non-resident treatment applies for that year (18% flat). Annual tax return filing: due May 31 of the following year. Electronic filing via eTax (etax.nat.gov.tw) with ARC (Alien Resident Certificate) number. Exit clearance (稅務規費繳清): the National Taxation Bureau requires tax clearance before departure for individuals with significant unpaid tax liabilities — banks may report foreign nationals' departing status. Practically: if your withholding is current and you have no large outstanding balance, exit clearance is not a barrier.
Labor Insurance (勞保) and Labor Pension Fund (勞退): Departure Refunds
Taiwan's labor protection system has two distinct components relevant to departing foreigners: (1) Labor Insurance (勞保 — Lao Bao, administered by Bureau of Labor Insurance — bli.gov.tw): mandatory social insurance for employed workers. Contributions: employee 20% of premium (approximately 1.1% of insured salary); employer 70%; government 10%. Labor Insurance provides: old-age benefits, disability, death, maternity. Old-age benefit for departing foreigners: if a foreign national permanently departs Taiwan without qualifying for old-age annuity (requires 15+ years of contributions), they may apply for a one-time old-age benefit lump-sum (老年一次金) equivalent to contributions × service months factor. Amount: calculated based on average insured monthly salary × months of insurance. Tax: subject to supplementary NHI premium (2.11%) deduction from the benefit (not income tax). Apply to BLI before or within a reasonable period after departure. (2) Labor Pension Fund — Individual Account (勞退個人帳戶 — administered by Bureau of Labor Funds — blf.gov.tw): separate from Labor Insurance. Employer contribution: 6% of monthly salary into your personal account (個人帳戶). Employee voluntary contribution: optional up to 6% additional. This account belongs to you and cannot be seized. Departure refund: when a foreign national permanently departs Taiwan, they are entitled to withdraw the entire accumulated balance of their Individual Pension Account (勞退個人帳戶), including employer contributions and investment returns. This is a key benefit — the full accumulated fund is yours on departure. Tax: the withdrawal is subject to income tax treatment (classified as pension income with exemptions).
National Health Insurance (全民健保): NHI on Departure
Taiwan's National Health Insurance (全民健保 — NHI, administered by National Health Insurance Administration — nhi.gov.tw) is one of the world's most comprehensive universal health systems. NHI coverage: all residents (including employed foreigners with ARC) are compulsorily enrolled. Premiums: employee 30% of premium (approximately 2.35% of insured salary); employer 60%; government 10%. NHI refund: NHI premiums paid do NOT generate a refundable account or future benefit outside Taiwan. There is no NHI lump-sum withdrawal. On departure: NHI coverage terminates on the date you surrender your ARC (Alien Resident Certificate). You lose access to Taiwan's healthcare network immediately. Supplementary NHI premium (二代健保補充費 — 2nd generation NHI supplementary premium): 2.11% applies to interest, dividend, rental income, labor insurance benefits, and professional service fees above TWD 20,000 per single payment. This supplementary premium is withheld at source by the payer. On departure: ensure all supplementary NHI obligations are settled. ARC surrender: when you depart Taiwan and surrender your ARC at the National Immigration Agency (NIA — immigration.gov.tw), this terminates your Taiwan residency, NHI enrollment, and triggers final tax obligations. Retain copies of all Taiwan tax filings and NHI/Labor Insurance contribution records before surrendering your ARC.
House and Land Transaction Income Tax (房地合一稅): Real Estate Gains
Taiwan reformed its real estate capital gains tax regime in 2016 and significantly amended it in 2021 (effective July 2021 — 房地合一稅2.0). The House and Land Transaction Income Tax (HLTI) now applies to gains on properties sold by individuals. 2026 rates by holding period: (1) Held ≤1 year: 45% — designed to deter short-term speculation. (2) Held >1 to ≤2 years: 35%. (3) Held >2 to ≤5 years: 20% (non-resident) / 15% (resident with self-use home exemption conditions). (4) Held >5 to ≤10 years: 20% (non-resident) / 10% (resident with conditions). (5) Held >10 years: 15% (non-resident) / 10% (resident with conditions). Self-use home exemption (自用住宅用地): residents (individuals with household registration) who have lived in the property for 6+ years of the holding period may benefit from a lifetime exemption of up to TWD 4M gain. Non-residents: do NOT qualify for the self-use exemption — 15–45% applies depending on holding period. Calculation: taxable gain = selling price − acquisition cost − expenses − improvements − certain government-approved deductions. Filing: HLTI return must be filed within 30 days of the transfer date (not at year-end). This is separate from the annual Comprehensive Income Tax return. Land Value Increment Tax (土地增值稅 — LVIT): a separate tax administered by local governments on the increase in official land value — calculated on official government price tables, not market prices. LVIT: general rate 20–40%; self-use exemption rate 10%.
