The company didn't pay social security until a year later. Can I claim compensation?

If the unit fails to pay social security for one year, causing losses to the workers, it needs to compensate according to its actual losses. If the employee terminates the contract with the unit, the unit will pay one month's salary for each full year of work in the unit.

Legal objectivity:

Article 47 of the Labor Contract Law

The economic compensation shall be paid according to the standard of one month's salary for each full year of the employee's working years in the unit. For more than six months but less than one year, it shall be counted as one year; If it is less than six months, economic compensation of half a month's salary shall be paid to the workers.

If the monthly salary of workers is three times higher than the average monthly salary of local workers announced by the people's government of the municipality directly under the central government or the city divided into districts where the employer is located, the standard for paying economic compensation to workers is three times the average monthly salary of workers, and the longest period for paying economic compensation to workers shall not exceed 12 years.

The monthly salary mentioned in this article refers to the average salary of workers in the twelve months before the dissolution or termination of the labor contract.
