The Second Generation NHI Supplementary Premium has been implemented since January 1 this year (2013). According to the current National Health Insurance Act, withholding units such as companies and institutions should, after withholding the six individual supplementary premiums, complete the withholding details filing process before January 31, 2014 for the National Health Insurance Administration (NHIA) to collect and organize data and to issue proof of payment of the individual health insurance premium, which will then be submitted to the financial tax units as basis for individual income tax deduction. However, according to the NHIA data, most withholding units have not filed withholding details to date. 

NHIA explains that withholding units can use the PC version software provided by the Administration to produce files of the withholding details, or produce their own file and then submit it to the NHIA via the internet platform to complete the filing process. However, the process requires an electronic certificate in order to log in to the platform, resulting in some withholding units having yet completed the filing. To meet such demands of the withholding units, in addition to the original certificate-based filing, the NHIA has added a new function of certificate-free internet filing of various income tax deductible supplementary premiums. In order to avoid internet traffic at the end of January next year due to the majority of withholding units filing at the same time, it is recommended that a person charged with withholding duty file the existing data first, and make good use of the value-added internet services. 

NHIA reminds the public that the Administration takes caution in data processing. A withholding unit should check for an e-mail confirmation after the certificate-free withholding details filing, and reply to the e-mail in seven days (holidays included) to confirm the filed data in order to complete the data transmission for the Administration to proceed with the data processing. The withholding unit can also submit query on the same platform for progress of the filed data processing. After the NHIA has finished processing the filed data (approximately three working days), a receipt or error statement will be e-mailed to the withholding unit. 

In case of any confusion or questions regarding the filing process, please feel free to call the NHIA toll-free service line: 0800-030-598.
