Tax health insurance can generally be purchased by individuals such as China People's Insurance Company, Taikang Pension Insurance Company, Ping An Insurance Company and Pacific Insurance Company. However, it should be noted that if an individual wants to buy tax health insurance, the premise is that the unit where the individual works has the relevant authority to open it. Individuals can't actually buy tax health insurance if individual units don't have access to tax health insurance.
Tax-preferential health insurance is essentially a one-year universal medical insurance, and its policy has a tax-preferential identification code, which can be used to deduct personal income tax.
