How to Correctly Compute 13th Month Pay in the Philippines

In the Philippines, the 13th Month Pay is not a mere Christmas bonus or a discretionary gift from an employer; it is a mandatory statutory benefit. Governed by Presidential Decree No. 851 and further clarified by the Department of Labor and Employment (DOLE) through various Labor Advisories, this benefit ensures that workers have additional liquidity during the holiday season.


1. Legal Basis and Coverage

The 13th Month Pay Law (P.D. 851) mandates that all employers in the private sector pay their rank-and-file employees a 13th month pay, regardless of the nature of their employment and irrespective of the method by which their wages are paid.

Who is Entitled?

To be eligible for the 13th month pay, an employee must meet the following criteria:

  • Rank-and-file status: Managerial employees are not legally entitled to this benefit under P.D. 851, although many companies grant it as a matter of policy or through Collective Bargaining Agreements (CBA).
  • Length of Service: The employee must have worked for at least one (1) month during the calendar year.

Who is Excluded?

  • Managerial employees (as defined by the Labor Code).
  • Employees already receiving a Christmas bonus equivalent to at least one month's salary.
  • Government employees (covered by separate civil service laws and different bonus structures).
  • Commission-based agents (where the commission is the sole source of income).

2. The Computation Formula

The minimum 13th month pay required by law shall not be less than one-twelfth (1/12) of the total basic salary earned by an employee within a calendar year.

The Mathematical Formula:

$$\text{13th Month Pay} = \frac{\text{Total Basic Salary Earned During the Calendar Year}}{12}$$

Defining "Basic Salary"

"Basic Salary" includes all remunerations or earnings paid by an employer to an employee for services rendered. However, it excludes the following, unless these are integrated into the basic salary by individual or collective agreement:

  • Cost of Living Allowance (COLA)
  • Profit-sharing payments
  • Overtime pay
  • Night shift differential
  • Holiday pay
  • Unused vacation and sick leave credits converted to cash

Note: Maternity leave benefits are not included in the "total basic salary" because there is no employer-employee relationship regarding wage payment during that period (the benefit is paid by the SSS).


3. Sample Computation

Consider an employee with a monthly basic salary of ₱20,000 who worked for the entire year without any unpaid absences.

Month Monthly Basic Salary Deductions (Absences/LWP) Total Earned
Jan - Oct ₱20,000 x 10 ₱0 ₱200,000
November ₱20,000 ₱2,000 (2 days absent) ₱18,000
December ₱20,000 ₱0 ₱20,000
TOTAL ₱238,000

Calculation: $$\text{13th Month Pay} = \frac{₱238,000}{12} = ₱19,833.33$$


4. Pro-rated 13th Month Pay

An employee who resigns or whose services are terminated at any time before the time of payment of the 13th month pay is still entitled to this benefit. This is called the pro-rated 13th month pay.

The amount is in proportion to the time the employee worked during the year, from the time they started (or January 1st) until the time of their resignation or termination.

Example: If an employee worked from January 1 until June 30 with a total earned basic salary of ₱120,000: $$\text{Pro-rated Pay} = \frac{₱120,000}{12} = ₱10,000$$


5. Deadlines and Compliance

Payment Deadline

The 13th month pay must be paid on or before December 24 of every year. Employers are encouraged to pay earlier to assist employees with holiday expenses.

Compliance Report

Every employer is required to submit a compliance report to the nearest DOLE Regional Office not later than January 15 of the following year. The report must include:

  1. Name of establishment
  2. Address
  3. Principal product or business
  4. Total employment
  5. Total number of benefit recipients
  6. Total amount of benefits granted

6. Taxation of 13th Month Pay

Under the TRAIN Law (Republic Act No. 10963), the 13th month pay and other "other benefits" (such as productivity incentives and Christmas bonuses) are tax-exempt up to a maximum threshold.

  • Tax-Exempt Threshold: ₱90,000.
  • Any amount exceeding the ₱90,000 limit is subject to the regular income tax rates.

7. Important Considerations

  • Non-Diminution of Benefits: If an employer has been including overtime pay or other allowances in the 13th month pay computation for a long period, they may be barred from suddenly excluding them under the principle of "non-diminution of benefits."
  • Late Payment: Failure to pay the 13th month pay is considered a money claim case. Employees may file a complaint with the DOLE, which can lead to inspections and orders to pay with potential legal interest.
  • Kasambahays: Under the Batas Kasambahay (R.A. 10361), domestic workers are also entitled to a 13th month pay equivalent to one-twelfth of their total basic salary earned in a year.
