Under Philippine law, the Social Security System (SSS) is a mandatory social insurance program designed to provide protection to workers against the hazards of disability, sickness, maternity, old age, death, and other contingencies. The primary law governing this is Republic Act No. 11199, otherwise known as the Social Security Act of 2018.

Failure by an employer to remit these contributions is not merely a breach of administrative duty; it is a criminal offense.

The Legal Mandate of the Employer

The Social Security Act imposes a strict "mandatory" nature on contributions. Once an employment relationship is established, the following duties arise for the employer:

Mandatory Deduction: The employer must deduct the employee's share of the monthly contribution from their salary.
Employer Share: The employer must provide their prescribed counterpart contribution.
Timely Remittance: The employer must remit both the employee and employer shares to the SSS within the first ten (10) days of the month following the applicable month (or based on the prescribed schedule based on the employer's ID number).

Important Legal Doctrine: The law states that even if the employer fails to remit the contributions, the employee's right to benefits remains protected, provided there is proof that the employment existed and the deductions were made.

Step-by-Step Actions for the Employee

If you discover that your contributions are not being posted, you should follow this structured approach to protect your rights.

1. Verification of Records

Before taking legal action, ensure the records are accurate. Employers sometimes have delays in posting due to SSS system issues rather than actual non-payment.

Check your My.SSS account via the SSS website or mobile app.
Request a Contribution Collection List (CCL) or a simple printout of your contributions from any SSS branch.

2. Internal Clarification (Demand Letter)

Request a meeting with your Human Resources or Accounting department. If the explanation is unsatisfactory, serve a formal written demand. This letter should:

State the specific months that are unremitted.
Request proof of payment (validated SSS Contribution Payment Form).
Give a specific period (e.g., 5 to 10 days) for the employer to rectify the records.

3. Filing a Formal Complaint with the SSS

If the employer ignores the demand or refuses to pay, proceed to the SSS Branch having jurisdiction over the employer’s place of business.

Approach the Member Assistance Center (MAC).
Fill out a Complaint Affidavit.
Required Documents: Payslips showing deductions, Employment Contract, or a Certificate of Employment (COE).

4. SSS Mediation and Legal Action

The SSS will assign an account officer to inspect the employer’s books. If the violation is confirmed, the SSS will issue a Notice of Violation. If the employer still refuses to comply:

The case is referred to the SSS Legal Department.
The SSS may file a criminal case for Violation of RA 11199 before the Prosecutor’s Office.

Penalties for Non-Compliance

The law provides heavy sanctions for employers who fail to remit or who deduct contributions but fail to remit them (which may also constitute Estafa under the Revised Penal Code).

Type of Liability	Description
Administrative Interest	A penalty of 2% per month from the date the contribution fell due until paid.
Criminal Liability	Imprisonment of 6 years and 1 day to 12 years.
Fines	A fine ranging from Php 5,000 to Php 20,000.
Civil Liability	The employer is liable to the SSS for the unpaid contributions and the value of any benefits the employee missed out on due to the non-remittance.

Crucial Reminders for Employees

Presumption of Deduction: Under the law, if an employer fails to remit contributions, it is presumed that they were deducted from the employee’s salary if the employee was actually working during that period.
The "Trust Fund" Doctrine: Contributions are considered "trust funds." Once deducted from your salary, that money no longer belongs to the employer; they are merely holding it in trust for the SSS. Misappropriating these funds is a serious crime.
Condonation Programs: Occasionally, the SSS offers "Contribution Condonation Programs" which allow employers to pay back arrears without the 2% monthly penalty. If your employer claims financial hardship, they should be encouraged to apply for these programs to settle your records.

Failure to remit SSS contributions deprives workers of their safety net. By law, the responsibility for remittance rests solely on the employer, and any agreement between the employer and employee to "waive" SSS coverage is null and void for being contrary to public policy.
