After investment immigration, am I still a Taiwan tax resident and NHI insured? Household registration, days of stay, and new NHI rules
Many people think that “living abroad for 183 days a year means you are not a Taiwan tax resident,” but this standard actually applies to foreign nationals (those without household registration in Taiwan). As long as you have household registration in Taiwan, the threshold is much stricter: residing in Taiwan for a total of 31 days or more in a tax year still makes you a “resident individual”; even if you reside less than 31 days, you may still be deemed a resident if your life and economic center remain in Taiwan. As for NHI, the “suspension and reinstatement” system was abolished at the end of 2024, and the rules have changed accordingly. Below, we break down the actual determination methods for Taiwan tax residency and NHI eligibility for your reference when planning after obtaining foreign status.
“183 days” is the standard for foreign nationals, not for those holding Taiwan household registration.
The Income Tax Act classifies “resident individuals of the Republic of China” into two categories: ① Those with household registration in Taiwan: if they reside in Taiwan for a total of 31 days or more in the tax year, they are resident individuals; if they reside for 1 day or more but less than 31 days, but their life and economic center are in Taiwan, they are also considered residents. ② Those without household registration in Taiwan: if they reside in Taiwan for a total of 183 days or more in the tax year, they are resident individuals. In other words, the common saying “living abroad for 183 days means you are not a Taiwan tax resident” only applies to foreigners who never had household registration in Taiwan. For those holding Taiwan household registration, the threshold is 31 days, and as long as the registration remains, it is generally difficult to be deemed a non-resident solely by residing less than 31 days.

The key factor that truly changes the determination: household registration removal.
Under the Household Registration Act, if you have been abroad for more than 2 years, you should apply for household registration removal. If you have been abroad for 2 years or more without any entry record using a Republic of China (Taiwan) passport, the household registration authority will proactively remove your household registration. After removal, the tax determination will revert to the rule for “individuals without household registration in Taiwan” (residing in Taiwan for 183 days or more in a year to be considered a resident). In other words, simply being abroad without actually returning to Taiwan is not enough; typically, the conditions for household registration removal must be met before the basis for tax resident status truly changes. Actual case determinations are still subject to review by the tax authorities.

New NHI Rules: The “suspension and reinstatement” system was abolished at the end of 2024; eligibility is now tied to household registration status.
In the past, long-term expatriates often remembered to apply for NHI “suspension” before going abroad, suspending coverage while overseas and reinstating it upon return, thereby avoiding premium payments during their stay abroad. This suspension and reinstatement system was abolished on December 23, 2024, and the National Health Insurance Administration no longer accepts new suspension applications. Under the new system, NHI eligibility is directly tied to household registration status: as long as your household registration remains in Taiwan, you are generally required to maintain NHI coverage and pay premiums as stipulated; only after your household registration is moved abroad will you lose NHI eligibility and be unenrolled. In other words, “remember to suspend NHI before going abroad” is now a thing of the past; the relevant question becomes “Is my household registration still in Taiwan?”

Household Registration Removal and Reinstatement: How NHI and Tax Status Change
If your household registration has been moved abroad and you later wish to return to Taiwan, the waiting period for NHI reinstatement varies by the duration of absence: if household registration is reinstated within 2 years of removal (i.e., abroad for less than 4 years), coverage can be reinstated on the same day; if reinstated after more than 2 years of removal (i.e., abroad for more than 4 years), you must wait 6 months from the date of reinstatement to re-enroll. Tax resident status will be recalculated based on the rules for “those with household registration” after reinstatement and actual return to Taiwan. When planning long-term stays abroad or return schedules, it is advisable to consider both the NHI waiting period and tax status together.
Obtaining a golden visa is a separate matter from severing Taiwan tax residency.
Obtaining a foreign residence permit or second passport only changes your status in the destination country; it does not automatically sever your tax residency or NHI coverage in Taiwan—these are governed by separate rules in Taiwan and the destination country, which do not automatically interact. If your goal is to actually reduce your tax ties to Taiwan, you generally need to simultaneously: ① substantially reduce your days of physical presence in Taiwan and genuinely relocate your life and economic center abroad, and ② evaluate the impact of moving your household registration (including military service, NHI, and other civil rights) based on your personal circumstances. This involves significant personal rights and long-term planning, and it is recommended to consult professionals familiar with Taiwan’s tax laws and household registration regulations for case-specific advice.

Frequently Asked Questions
If I live abroad for 183 days, am I no longer a Taiwan tax resident?
Not necessarily. The 183-day rule applies to “individuals without household registration in Taiwan.” As long as you still have household registration in Taiwan, the threshold is that you are considered a resident individual if you reside in Taiwan for a total of 31 days or more in the tax year. Even if you reside less than 31 days, you may still be deemed a resident if your life and economic center remain in Taiwan. Simply living abroad for more than 183 days, while retaining household registration in Taiwan, does not necessarily change your tax resident status; the actual determination is made by the tax authorities on a case-by-case basis.
Under what circumstances will my household registration be removed?
Under the Household Registration Act, if you have been abroad for more than 2 years, you should apply for household registration removal. If you have been abroad for 2 years or more without any entry record using a Republic of China (Taiwan) passport, the household registration authority will proactively remove your household registration. After removal, the tax resident determination will shift to the standard for “individuals without household registration in Taiwan” (183 days).
Do I still need to suspend my NHI before going abroad?
No longer needed. The NHI suspension and reinstatement system was abolished on December 23, 2024. The National Health Insurance Administration no longer accepts suspension applications. Under the new system, NHI eligibility is tied to household registration status: if your household registration remains in Taiwan, you are generally required to maintain coverage and pay premiums; only after your household registration is moved abroad will you lose eligibility and be unenrolled according to regulations.
If I move my household registration back to Taiwan after removal, how long does it take to reinstate NHI?
It depends on the duration of absence: if household registration is reinstated within 2 years of removal (i.e., abroad for less than 4 years), NHI coverage can be reinstated on the same day; if household registration is reinstated after more than 2 years of removal (i.e., abroad for more than 4 years), you must wait 6 months from the date of reinstatement to re-enroll in NHI.
Will obtaining a golden visa or second passport automatically make me no longer a Taiwan tax resident?
No. Obtaining a foreign residence card or citizenship changes your status in the destination country but does not automatically alter your tax domicile or National Health Insurance eligibility in Taiwan—these are governed by separate rules in Taiwan and the destination country. If your goal is to effectively reduce your tax ties to Taiwan, you generally need to separately address factors such as days of physical presence, center of vital interests, and household registration status.
Whom should I consult for accurate confirmation?
Tax resident status is determined on a case-by-case basis. It is recommended to consult the tax authorities at your registered household location or the Ministry of Finance Tax Portal for current regulations; for NHI eligibility changes, contact the National Health Insurance Administration; for household registration removal/reinstatement rules, contact the household registration office or the Department of Household Registration.
