Generally, units are allowed to default on social security for several months.

First, units are generally allowed to pay social security for several months.

1, social security will be broken if it is not paid within 3 months. Insured persons should be insured within 3 months after being included in the social security scope. If they fail to go through the insurance formalities within the specified time, or the payment is continuously interrupted for 3 months, it will be regarded as the interruption of insurance. After the interruption, you can go through the insurance procedures and pay for 6 months in a row before you can enjoy medical insurance benefits.

2. Legal basis: Article 58 of People's Republic of China (PRC) Social Insurance Law.

The employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for its employees. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay.

Article 63

If the employer fails to pay social insurance premiums in full and on time, the social insurance premium collection agency shall order it to pay or make up within a time limit. If the employer fails to pay or repay the social insurance premium within the time limit, the social insurance premium collection agency may inquire about its deposit account in banks and other financial institutions; And can apply to the relevant administrative departments at or above the county level to make a decision on the allocation of social insurance premiums, and notify their bank or other financial institutions in writing to allocate social insurance premiums. If the balance of the employer's account is less than the social insurance premium that should be paid, the social insurance premium collection agency may require the employer to provide guarantee and sign a deferred payment agreement.

Second, does unpaid social security affect the payment of the next unit?

Social security arrears do not affect the payment of the next unit. But if the last unit is in arrears, it will affect the payment of the next unit, as long as the individual is in arrears. As long as the payment is suspended and the account number is provided to the new unit to increase staff, the new unit can continue to pay the fee, which can be calculated together with the previous payment period. If the last unit owes money, the next unit can't pay it back without paying it back.
