Taiwan tax residency: the 183-day rule
Taiwan treats you as a tax resident at 183 days in the calendar year (1 January – 31 December) — but the day count is only the part we can calculate. It is one of Taiwan's tests, not the whole rule (see the others below). Source: National Taxation Bureau, Ministry of Finance (R.O.C.), last reviewed 2026-05-27.
183 days isn't the only route — Taiwan can also treat you as resident on non-day grounds (domicile + habitual residence, household registration (registered-status concept), centre of vital interests, family ties). See every test below.
Spend 183 days or more in Taiwan during the calendar year (1 January – 31 December) and it will generally treat you as a tax resident for that period.

How does Taiwan count days for tax residency?
According to National Taxation Bureau, Ministry of Finance (R.O.C.), you become a tax resident of Taiwan once you spend 183 days or more there in the calendar year (1 January – 31 December). Because the count is per calendar year, it resets every 1 January and days from a previous year do not carry over — though a single stay that spans New Year is split across two years’ totals.
183-day rule
183 days · the calendar year (1 January – 31 December)Spend 183 days or more in Taiwan during the calendar year (1 January – 31 December) and it will generally treat you as a tax resident for that period.
Foreign nationals are resident for tax purposes if they stay in the R.O.C. for 183+ days in a taxable year. Days are counted from passport entry/exit stamps; multiple stays accumulate.
What else makes you a tax resident of Taiwan?
The day count is only one route. Taiwan can also make you a tax resident through any one of the following — regardless of how few days you spend there. These don't depend on a day count, so Yuravia can't track them for you; weigh them against your own situation.
Domicile + habitual residence
Income Tax Act Art. 7(2)(1): an individual who has a domicile (legal/permanent home) within the ROC and habitually resides there is a resident irrespective of day count (subject only to the 31-day carve-out), so anyone domiciled in Taiwan is presumptively a worldwide-income resident.
Household registration (registered-status concept)
Holding an active household registration (戶籍) in Taiwan is the practical proxy for domicile used by the tax authority; a registered national is treated under the domicile/31-day framework rather than the 183-day rule applied to aliens.
Centre of vital interests
For domiciled/registered persons present 1-30 days, residency turns on whether their centre of vital/economic interests is in Taiwan, evidenced by entitlement to Taiwan social-security/National Health Insurance benefits, a spouse or dependent (minor) child residing in Taiwan, or ongoing economic/financial activities (business, employment, property management) in Taiwan.
Family ties
A spouse or dependent minor child residing in Taiwan is an explicit factor establishing the centre of vital interests, and thus can make a low-presence domiciled individual a resident.
Taiwan at a glance
- Tax year
- 1 January – 31 December (calendar year). The official instructions state the taxable year is "a full year from January 1 to December 31."
- How days are counted
- Days are counted from passport/immigration entry-exit records excluding the date of arrival and including the date of departure; if a person enters and leaves multiple times in a taxable year, the days are accumulated to reach 183.
- What residency means
- A foreign national staying 183+ days in a calendar year is a tax resident, filing on a progressive 5–40% scale; however Taiwan's regular income tax is essentially territorial — both residents and non-residents are taxed only on Taiwan-source income. Residents are additionally subject to the Income Basic Tax (alternative minimum tax, flat 20%), under which foreign-source income is included only if it is TWD 1M+ and basic income exceeds the threshold (TWD 7.5M for 2025), so foreign income is not fully taxed as under a classic worldwide system.
- Notable regime
- Foreign (Special) Professionals tax incentive under the Act for the Recruitment and Employment of Foreign Professionals (incl. Employment Gold Card holders): for first-time qualifying professionals, 50% of annual salary income exceeding TWD 3 million is excluded from income tax for 5 years (in each year they stay 183+ days), provided they had no Taiwan household registration and were not Taiwan tax residents in the prior 5 years.

Frequently asked questions
How many days can I stay in Taiwan without becoming a tax resident?
According to National Taxation Bureau, Ministry of Finance (R.O.C.), Taiwan treats you as a tax resident at 183 days in the calendar year (1 January – 31 December) (the "183-day rule"). Staying under that is necessary but not sufficient — a permanent home, family, or your centre of vital interests can make you resident on fewer days.
Is the day count the only way to become a tax resident of Taiwan?
No. Beyond the day count, Taiwan can treat you as resident through domicile + habitual residence, household registration (registered-status concept), centre of vital interests, family ties — any one of these can apply even if you stay well under 183 days. They don't depend on counting days, so confirm them against your own circumstances.
What counts as a day of presence in Taiwan?
In most jurisdictions any day on which you are physically present — including the arrival and departure days — counts as a full day. Treating both as counted is the conservative assumption. Always confirm the exact rule with National Taxation Bureau, Ministry of Finance (R.O.C.).
What is the official source for Taiwan's tax-residency rule?
