Do I have to pay personal income tax if I don't buy social security?

If you don't buy social security, you need to pay personal income tax.

Social security and individual tax are two independent concepts. Although both people need to pay, the nature of payment is different. Social security is compulsory, and personal income tax is paid monthly. There is no necessary connection between them. According to Item 1, Paragraph 1, Article 6 of the Individual Income Tax Law of People's Republic of China (PRC), the special deduction includes social insurance premiums and housing accumulation fund such as basic old-age insurance, basic medical insurance and unemployment insurance paid by individual residents in accordance with the scope and standards stipulated by the state.
