According to the laws governing national health insurance, every five years a new set of rates should be calculated to cover the following five years. In addition, whenever the system's reserve fund goes below the equivalent of medical costs for one month (currently, that figure is about NT $ 250 billion), then the insurance rates can be raised automatically.
根據健保法規定，每五年應該精算出維持「下一個五年」的費率，且當健保「安全準備金」低於一個月的醫療費（約兩百五十億元）時，健保可自動調漲費率。
