# Taiwan Personal Tax Basics

Taiwan's income-tax residence rules combine domicile and presence, while local-source income and overseas-income basic tax follow different rules. Foreign payment is not enough to make work done in Taiwan foreign-source.

Scope: Selected individual residence, local work income, filing and overseas basic-income-tax principles, with the narrowly qualified foreign-special-professional relief identified. This is not a full tax calculation or treaty determination.

Jurisdiction: Taiwan: individual income taxation. Sources reviewed 2026-09-22; review due 2026-12-21.

General information, not personal tax advice. Nationality, tax residence and source of income are different questions. Consult the tax authority or a qualified adviser for your circumstances.

## Domicile with habitual residence, or at least 183 days

Article 7 treats an individual as resident if domiciled and habitually resident in the territory, or, without that domicile, present for at least 183 days during the tax year. The second route is inclusive of day 183; citizenship or a residence permit alone does not replace the statutory tests.

Evidence: conditional. [Taiwan Ministry of Justice, Laws and Regulations Database: Income Tax Act Article 7: individual residence](https://law.moj.gov.tw/LawClass/LawSingle.aspx?pcode=G0340003&flno=7). Source location: Income Tax Act Article 7(2)(1)-(2), operative Chinese text.

## Calendar-year visits are combined

MOF's alien-tax instructions use the calendar year and add separate visits together. Arrival day is excluded and departure day is included. The annual tax count should not be substituted for the multi-year immigration or naturalisation residence calculation.

Evidence: documented.

Source location: Instructions section I, tax year and calculation of days of residence, points 3-4.

## Local work can be taxable despite overseas payroll

Compensation for work performed in Taiwan is generally local-source. Article 8 has a limited exception for a nonresident staying no more than ninety days in the year and paid by an overseas employer. It does not exempt all foreign-paid workers or everyone staying fewer than 183 days.

Evidence: conditional. [Taiwan Ministry of Justice, Laws and Regulations Database: Income Tax Act Article 8: local-source income](https://law.moj.gov.tw/LawClass/LawSingle.aspx?pcode=G0340003&flno=8); [Taiwan Ministry of Finance, eTax Portal: Alien income-tax instructions, body for 2025 returns](https://www.etax.nat.gov.tw/etwmain/en/announcement/alien-individual-income-tax/instructions). Source location: Income Tax Act Article 8(3); MOF instructions section I.1, distinctions between stays up to 90 days, over 90 but under 183, and at least 183.

## Withholding does not resolve every filing obligation

The official instructions distinguish nonresident withholding from declarations for relevant income not fully dealt with at source, including locally earned pay from an overseas employer where taxable. Residents generally make an annual return in May, with departure-related filing rules requiring separate attention.

Evidence: conditional.

Source location: Instructions section I.1 and I.6, taxpayer categories and time of filing.

## Overseas income can enter the resident basic-tax calculation

Resident overseas income is not simply ignored: MOF says qualifying overseas income of at least NT$1 million enters the basic-income calculation. That inclusion alone does not mean extra tax is payable; the comparison with ordinary income tax, applicable deduction and other rules still matter. Any credit for overseas tax is subject to a limit, not an automatic full refund.

## Foreign-special-professional relief is conditional

Qualifying foreign special professionals under Article 22 and its tax-relief regulations can obtain five-year relief starting with their first qualifying year of at least 183 days and professional salary above NT$3 million. The benefit excludes half the salary above that amount from ordinary income and overseas income from basic income, subject to the statutory conditions and an application with supporting evidence; it is not available merely because a worker is foreign.

## Scope and limitations

- The English instruction page retains a 2024 heading, but its actual body addresses 2025 returns filed in 2026 and was updated on 27 April 2026. Only its baseline counting, source and filing explanations are used here; its dated rate, exemption and deduction tables are not republished as 2026 amounts.
- The overseas basic-income-tax mechanism, local-source tax and special-professional relief are distinct. Treaty relief, household circumstances, foreign-controlled entities and separate property taxes require additional analysis.
- The special-professional FAQ summarises a qualified regime, not its complete eligibility checklist. Residence or a work permit alone is not proof that the exemption applies.
