13th Month Pay Computation (Philippines)

A 13th Month Pay Computation in the Philippines sets out the rights and obligations of the parties on the matter it concerns and records the terms they have agreed.

The basic computation formula under the DOLE Revised Guidelines is: 13th Month Pay = Total Basic Salary Earned During the Calendar Year ÷ 12. For this purpose, 'basic salary' means the fixed or guaranteed wage paid for services rendered before deductions for SSS, PhilHealth, Pag-IBIG (HDMF), and withholding tax, and excludes allowances, overtime pay, premium pay, night shift differential, holiday pay, cost of living allowances (COLA), profit-sharing payments, and other monetary benefits not integrated into the basic salary. The Supreme Court of the Philippines, in Boie-Takeda Chemicals v Dela Serna (G.R. No. 92174, December 10, 1993), confirmed that commissions paid to employees may be excluded from the basic salary base unless they form part of the fixed guaranteed compensation.

The 13th month pay must be paid on or before December 24 of each year. However, employers may, at their discretion, pay one-half of the 13th month pay before the opening of the regular school year in May and the remaining one-half on or before December 24 — a practice common among large Philippine corporations disclosed in their CBA provisions and employee handbooks. Under Section 6 of the NIRC (National Internal Revenue Code), as amended by the Tax Reform for Acceleration and Inclusion (TRAIN) Law (RA 10963, effective January 1, 2018), the 13th month pay and other benefits are exempt from income tax up to PHP 90,000 per year. Amounts exceeding PHP 90,000 are subject to withholding tax and must be reflected in the BIR Form 2316 (Certificate of Compensation Payment/Tax Withheld) filed annually.

All rank-and-file employees who have worked for at least one month during the calendar year are entitled to 13th month pay, pro-rated based on the number of months or fraction thereof actually worked. Managerial employees as defined under Article 82 of the Labor Code are excluded from the mandatory PD 851 coverage, but may receive 13th month pay under company policy or CBA. Employees of the national government and its political subdivisions, including government-owned and controlled corporations (GOCCs), are excluded from PD 851 but may receive year-end bonus under the General Appropriations Act (GAA) administered by the Department of Budget and Management (DBM).

A 13th Month Pay Computation Worksheet is needed in the Philippines in the following situations.

A 13th Month Pay Computation Worksheet is required for every covered rank-and-file employee before December 24 of each calendar year, when the employer computes and processes the mandatory 13th month pay payment under PD 851 to confirm compliance and avoid penalties.

A 13th Month Pay Computation Worksheet is needed when computing pro-rated 13th month pay for employees hired during the calendar year, to determine the fractional entitlement based on the number of months actually worked from the date of hire to December 31.

A 13th Month Pay Computation Worksheet is required when an employee resigns, is terminated, or is separated at any time during the calendar year — as DOLE Labor Advisory No. 06-20 mandates inclusion of proportionate 13th month pay in the final pay, computed for the period from January 1 (or hire date) to the last day of employment.

A 13th Month Pay Computation Worksheet is needed to support the employer's DOLE Establishment Report filing required under Department Order No. 183-17, where 13th month pay compliance is one of the labor standards inspected.

A 13th Month Pay Computation Worksheet is required to accurately compute the taxable and non-taxable portions of the 13th month pay — the first PHP 90,000 per year is exempt from income tax under RA 10963 (TRAIN Law), while excess amounts are subject to withholding tax reportable on BIR Form 2316.

Parties in Philippines should prepare a 13th Month Pay Computation (Philippines) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under Philippine law, the Civil Code of the Philippines (Republic Act No. 386) governs contractual obligations. The Revised Corporation Code (Republic Act No. 11232) regulates corporate entities through the Securities and Exchange Commission (SEC). The Labor Code of the Philippines (Presidential Decree No. 442) and Department of Labor and Employment (DOLE) govern employment matters. The Data Privacy Act of 2012 (Republic Act No. 10173) and the National Privacy Commission (NPC) protect personal data. The Bureau of Internal Revenue (BIR) administers tax obligations under the National Internal Revenue Code. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A valid Philippines 13th Month Pay Computation Worksheet contains the following essential elements.

Employee Information: Full name, employee ID, department, position, and employment status (regular, probationary, project-based, or casual), confirming rank-and-file classification for PD 851 coverage.

Computation Period: January 1 to December 31 of the calendar year, or the pro-rated period from the hire date or last day of employment for partial-year employees.

Monthly Basic Salary Breakdown: Month-by-month listing of the basic salary earned, excluding overtime, allowances, COLA, and other non-basic components, in Philippine Pesos (PHP).

Total Basic Salary for the Year: Sum of all monthly basic salary amounts earned during the computation period.

13th Month Pay Formula: Total Basic Salary Earned ÷ 12 = 13th Month Pay. For pro-rated computation: (Total Basic Salary Earned ÷ 12) × (Number of Months Worked ÷ 12) — or more accurately, Total Basic Salary Earned ÷ 12, which naturally pro-rates since only months with income are included.

Tax Exemption Computation: Identification of the exempt portion (up to PHP 90,000 combined 13th month pay and other benefits under RA 10963 TRAIN Law) and the taxable excess, if any, for withholding tax computation and BIR Form 2316 reporting.

Payment Schedule: Date of payment (on or before December 24) and, if split, dates of the May and December installments.

Payroll Officer Certification: Signature of the payroll officer confirming accuracy, and acknowledgment receipt signed by the employee upon payment.
