NHI Supplementary Premium Withholding and Payment

Answer
Q: Is the NHI supplementary premium the same as the second-generation NHI (2nd gen NHI)?
A:
Yes. The 2nd gen NHI which came into effect on 1 January 2013, was introduced to make the premium system fairer and to improve the financial sustainability of Taiwan’s NHI program. Under the 2nd gen NHI, health insurance premiums consist of two components:
  1. General Insurance Premium - This is the same as the traditional NHI premium and is calculated primarily based on an individual's regular salary or wages.
  2. Supplementary Insurance Premium - This applies to certain additional sources of income. For example, if an individual receives a bonus exceeding four times their insured monthly salary, or earns professional service income, dividend income, interest income, rental income, or part-time income paid by an employer other than the insured unit, the paying entity is generally required to withhold a 2.11% NHI supplementary premium on the applicable amount.

Q:
When is the NHI supplementary premium required to be withheld?
A:
A 2.11% NHI supplementary premium must be withheld when any of the following types of income meet the applicable threshold (or exceed the prescribed cumulative limit):

  2. Part-time Salary Income – Part-time salary paid to an individual who is not enrolled in NHI through the paying entity, where a single payment is equal to or exceeds the statutory minimum monthly wage (currently TWD 29,500).
