In the Philippine labor landscape, the 13th month pay is a mandatory benefit that often raises questions when intertwined with statutory leaves—most notably, maternity leave. To navigate this, one must look at the intersection of Presidential Decree No. 851 (The 13th Month Pay Law) and Republic Act No. 11210 (The 105-Day Expanded Maternity Leave Law).
The Legal Framework
Under Presidential Decree No. 851, all rank-and-file employees in the private sector are entitled to a 13th month pay, provided they have worked for at least one month during the calendar year.
The "13th month pay" is defined as one-twelfth (1/12) of the total basic salary earned by an employee within a calendar year. The key phrase here is "basic salary earned."
How Maternity Leave Affects the Computation
The fundamental rule in Philippine labor law is "no work, no pay," unless a specific law or company policy states otherwise. When an employee goes on maternity leave, they are technically not rendering service to the employer.
While the Expanded Maternity Leave (EML) law ensures the employee receives her full pay (through SSS benefits and the employer’s salary differential), these payments are classified as social security benefits and administrative differentials, not "basic salary earned" for the purpose of 13th month computation.
What is excluded from "Basic Salary"?
For the purposes of computing 13th month pay, the following are generally excluded:
- Overtime pay
- Night shift differential
- Holiday pay
- Unused vacation and sick leave credits converted to cash
- Maternity leave benefits
The Mathematical Formula
The computation is straightforward but must account for the months or days the employee was physically at work (or on paid leaves like SL/VL, if company policy treats those as part of the basic salary).
$$\text{13th Month Pay} = \frac{\text{Total Basic Salary Earned During the Calendar Year}}{12}$$
Illustrative Example
An employee earns ₱30,000 per month. She goes on maternity leave for 105 days (roughly 3.5 months) from July to mid-October.
| Month | Employment Status | Basic Salary Earned |
|---|---|---|
| January - June | Active Work | ₱180,000 (₱30k x 6) |
| July - September | Maternity Leave | ₱0 |
| October | Returned (Half Month) | ₱15,000 |
| November - December | Active Work | ₱60,000 (₱30k x 2) |
| Total Earned | ₱255,000 |
Computation: $$\frac{₱255,000}{12} = ₱21,250$$
In this scenario, the employee receives ₱21,250 as her 13th month pay, rather than a full month's salary of ₱30,000, because she did not "earn" basic salary during the period she was on maternity leave.
Employer Differential and 13th Month Pay
Under RA 11210, employers are required to pay a salary differential—the difference between the employee’s full salary and the SSS maternity benefit.
The Department of Labor and Employment (DOLE) has clarified through various advisories that this differential is not included in the computation of the 13th month pay. It is treated as a benefit to ensure the employee maintains her income level during her recovery and infant care, but it does not count as "service rendered" for the 13th month calculation.
Key Compliance Deadlines and Rules
- Deadline: The 13th month pay must be paid on or before December 24 of every year.
- Taxation: Under the TRAIN Law, 13th month pay and other benefits are tax-exempt up to ₱90,000.
- Resignation/Termination: If an employee resigns or is terminated before the 13th month pay is distributed, they are still entitled to a proportionate amount based on the time they worked during that year.
- Company Policy: If a company’s CBA (Collective Bargaining Agreement) or established policy is more generous (e.g., counting maternity leave as part of the 13th month base), the company must follow that more favorable rule. Once a benefit becomes "established practice," it cannot be unilaterally withdrawn by the employer.
Summary of Principles
The 13th month pay for an employee on maternity leave is proportionate. While the law protects the employee’s tenure and provides for her income during the leave via the EML, the 13th month pay itself is strictly a reflection of the actual basic salary earned while in active service during the calendar year.
