Is it reasonable for the company to deduct wages when paying social security in the month of resignation?

Legal analysis: reasonable. The unit has the right to withhold and remit the personal part of your salary. If an employee leaves his job and works for less than one month in that month, the company needs to pay social security for that month. Moreover, individuals and units need to pay social security fees in accordance with the provisions of national documents, and there can be no illegal deduction in violation of the Social Insurance Law.

Legal basis: Article 12 of the Social Insurance Law of People's Republic of China (PRC), the employing unit shall pay the basic old-age insurance premium in proportion to the total wages of its employees as stipulated by the state and record it in the basic old-age insurance pooling fund.

Employees shall pay the basic old-age insurance premium in accordance with the proportion of wages stipulated by the state and record it in their personal accounts.

Individual industrial and commercial households without employees, part-time employees who have not participated in the basic old-age insurance in the employing unit and other flexible employees who have participated in the basic old-age insurance shall pay the basic old-age insurance premiums in accordance with state regulations and record them in the basic old-age insurance pooling fund and individual accounts respectively.
