Now that I am 46 years old, can I still pay social security?

You can pay. According to the inquiry, China Law Network shows that.

1. If there is no unit, you can apply for social security as a freelancer, but you can only pay pension and medical insurance. You need to bring your ID card to the social security service point of the local community street or the county-level social security bureau.

2. If there is a unit, it needs the unit to handle it. Legal basis: Article 16 of the Social Insurance Law of People's Republic of China (PRC) stipulates that individuals who have participated in the basic old-age insurance will receive the basic old-age pension on a monthly basis if they have accumulated contributions for fifteen years when they reach the statutory retirement age.
