Legality of Deducting SSS Premium from 13th Month Pay

Below is a comprehensive discussion of the legality (or illegality) of deducting Social Security System (SSS) contributions (premiums) from the 13th month pay in the Philippine setting. This discussion consolidates the pertinent laws, regulations, and administrative issuances relating to 13th month pay and SSS contributions, and it explains why—under prevailing rules—an employer generally should not deduct SSS contributions from the 13th month pay.


1. The Legal Basis for 13th Month Pay

  1. Presidential Decree (PD) No. 851

    • Enacted on December 16, 1975, PD 851 requires all employers to pay their rank-and-file employees a 13th month pay.
    • Generally, all rank-and-file employees who have worked at least one month during a calendar year are entitled to this benefit.
  2. Computation

    • Under PD 851, the minimum 13th month pay is computed as one-twelfth (1/12) of the employee’s basic salary earned within the calendar year.
    • In practice, many companies go beyond the minimum and give additional bonuses, but the legal obligation is only for the mandated 13th month pay under PD 851.
  3. Nature of 13th Month Pay

    • The 13th month pay is not treated as part of the “regular wage” for purposes of certain computations (e.g., overtime pay, holiday pay).
    • Nonetheless, it is still considered a mandatory benefit that must be paid on or before December 24 of each year, unless the employer is allowed by the Department of Labor and Employment (DOLE) to pay it on a different schedule (e.g., in two installments).

2. The Legal Framework for SSS Contributions

  1. Social Security Act (RA 11199)

    • Republic Act No. 11199 (Social Security Act of 2018) governs the rules on coverage and contributions to the SSS. This law superseded previous SSS laws (RA 1161, as amended by RA 8282).
    • The SSS law provides how much employers and employees must contribute to the SSS based on a prescribed schedule of contributions, usually determined by the employee’s monthly salary credit (MSC).
  2. Definition of “Compensation”

    • Under the SSS law and its implementing rules, “compensation” is generally defined as all actual remuneration for employment, including the mandated cost-of-living allowance and other forms of remuneration for services rendered.
    • However, certain items—such as de minimis benefits, certain allowances, and sometimes bonuses—may be excluded from the definition of compensation upon which SSS premiums are based.
  3. Monthly Salary Credit (MSC)

    • SSS contributions are computed monthly based on the MSC. There is a maximum monthly salary credit; once the salary or wage hits that maximum credit, the contribution does not increase further even if the employee receives additional compensation.

3. Is the 13th Month Pay Included in the Basis for SSS Contributions?

3.1 Common Practice and Administrative Guidance

  • General Exclusion from the Regular Wage Basis
    Although the 13th month pay is a mandatory benefit, it is generally treated similarly to a bonus for the purposes of SSS and other statutory contributions. In practice and according to prevailing interpretations, the 13th month pay is not included in the regular monthly wage base used to compute the SSS premium for a given month.

  • Not Payment for Services in a Given Month
    The logic behind excluding the 13th month pay from monthly SSS deductions is that it is not compensation for a single particular month’s work; rather, it is a statutory benefit that accrues over the course of the year. By design, it is akin to an annual bonus measured against total basic salary.

  • No Separate SSS Deduction
    Because the SSS imposes monthly contribution requirements (rather than an annual lump-sum requirement) and the 13th month pay does not count as part of that month’s “regular wage,” employers typically do not deduct SSS contributions from the 13th month pay.

3.2 Clarifications from DOLE and SSS Circulars

  • While the Social Security Act and its implementing rules do not always explicitly label “13th month pay” as excludable in the same sentence as “bonuses,” SSS guidance and labor practices in the Philippines have long established that:

    “If the remuneration is not part of the employee’s basic pay for a given pay period (month), it is generally not subject to SSS premiums.”

  • In many SSS or DOLE advisories, the 13th month pay is not singled out for monthly contributions. Employers are required to withhold and remit SSS contributions for the regular monthly salary, but not for a mandatory benefit that is computed and given at year-end (or in installments) outside of the monthly payroll structure.


4. The Tax and Contribution Treatment of 13th Month Pay

  1. Tax Treatment

    • Under the Tax Code (as amended, particularly by the TRAIN Law), the 13th month pay and other benefits (such as Christmas bonuses) are tax-exempt up to PHP 90,000 in a calendar year. Any amount in excess of PHP 90,000 is subject to withholding tax.
    • This tax exemption threshold does not affect whether SSS contributions apply; however, it underscores that the law treats the 13th month pay differently from regular wages.
  2. PhilHealth and Pag-IBIG

    • Similarly, for PhilHealth and Pag-IBIG (HDMF) contributions, the 13th month pay is generally not factored into the regular monthly salary base for computing mandatory contributions.
    • Some employees or employers, however, mistakenly combine the 13th month pay with monthly wages, but standard practice and official guidelines usually classify it as an excluded item for monthly premium calculations.

5. Consequences of Improper Deductions

  1. If SSS Premiums Are Deducted from the 13th Month Pay

    • Strictly speaking, if an employer withholds or deducts SSS contributions from an employee’s 13th month pay, the deduction is typically considered unwarranted, as it is not required by law.
    • This may be seen as a form of illegal deduction or underpayment of the 13th month pay, entitling the employee to recover the amount improperly deducted.
  2. Potential Labor Complaints

    • Employees who believe their 13th month pay has been improperly reduced can file a complaint before the Department of Labor and Employment or the National Labor Relations Commission.
    • If found to have violated labor laws or related social security guidelines, the employer may be ordered to return the deducted amounts plus possible penalties.
  3. Compliance Advice

    • Employers are advised to compute SSS contributions strictly on basic monthly salary (within the maximum salary credit) plus mandated allowances that are expressly included, excluding purely discretionary bonuses or mandated year-end benefits such as the 13th month pay.

6. Frequently Asked Questions

  1. Can an employer combine the 13th month pay with December’s salary and then deduct SSS contributions?

    • While administratively some employers release the 13th month pay together with the December salary, the standard is still to exclude that portion from the SSS contribution computation. The combined release is an accounting practice for convenience, but it does not change the legal treatment of the 13th month pay.
  2. If the 13th month pay is added to salary in December and the total is still below the maximum monthly salary credit, must the employer withhold an additional SSS contribution?

    • Under typical guidelines, the basis for SSS contribution is the employee’s regular monthly compensation for that December pay period. The 13th month pay (even if given simultaneously) remains excluded for contribution calculations.
  3. What if the employer calls a portion of the December pay a ‘bonus’ and lumps it with the 13th month pay—could this change the deduction rules?

    • Purely discretionary bonuses follow a similar pattern: discretionary bonuses not tied to a specific month’s work are ordinarily excluded from the SSS premium base. If the employer lumps them together, the label does not automatically trigger SSS deductions unless it is proven to be part of the employee’s “basic pay” structure.
  4. Is it ever legal to deduct from the 13th month pay for other reasons (e.g., loan repayments, authorized salary deductions)?

    • Deduction from wages or benefits can only be done if expressly allowed by law, regulation, or with the valid consent of the employee (e.g., for company loans). As for SSS contributions, there is no legal basis to deduct from the 13th month pay. For other deductions, the employer must follow the rules on lawful deductions under the Labor Code and DOLE regulations.

7. Summary and Key Takeaways

  1. 13th Month Pay is Mandated

    • PD 851 obliges employers to provide rank-and-file employees with a 13th month pay, computed as at least 1/12 of the total basic salary earned within the calendar year.
  2. Excluded from SSS Premium Computation

    • The 13th month pay is not generally treated as part of the monthly salary for which SSS premiums are due.
    • Consequently, it is not standard nor legally required to deduct employee SSS contributions from the 13th month pay.
  3. Illegal Deduction

    • An employer’s act of deducting SSS contributions from the 13th month pay can be deemed improper, and employees may seek restitution or file a complaint.
  4. Check for Maximum Monthly Salary Credit

    • The SSS system uses a monthly wage bracket; once the regular monthly salary hits the maximum salary credit, additional pay (including bonuses) typically does not increase the SSS contribution for that month.
  5. Employee Remedies

    • If an employer incorrectly deducts from the 13th month pay, employees may demand reimbursement or file a labor complaint. DOLE or the National Labor Relations Commission would generally uphold the employee’s right to a full 13th month pay.

8. Practical Tips for Employers and Employees

  • For Employers

    1. Separate the accounting for the 13th month pay from the regular payroll in December (or whenever it is disbursed).
    2. Adhere to the SSS contribution schedule (employee and employer shares) based on the monthly salary credit for actual monthly wages.
    3. When in doubt, consult the latest SSS circulars or DOLE advisories on allowable bases for deductions.
  • For Employees

    1. Verify payslips and check if any SSS deduction is applied to your 13th month pay.
    2. If you see deductions that you suspect are improper, raise the matter with your HR/payroll department.
    3. If unresolved internally, you may seek guidance from DOLE or file a labor complaint if the deduction is indeed inconsistent with labor or social security laws.

9. Conclusion

In the Philippines, the 13th month pay is a statutorily mandated year-end benefit governed by PD 851. Under the common interpretation of the Social Security Act and established labor practice, this benefit is excluded from the monthly basic salary that forms the basis for SSS contributions. Thus, it is not legal to deduct SSS premiums from the 13th month pay. Employees who encounter such deductions may demand rectification or seek remedies under labor dispute mechanisms.

Ultimately, both employers and employees should remain vigilant and informed about the proper treatment of the 13th month pay under labor laws and the correct computation of SSS, PhilHealth, and Pag-IBIG contributions to avoid any compliance issues. When in doubt, consulting official SSS and DOLE issuances or seeking professional legal advice is the best course of action.
