If you’re searching for the deadline on 13th month pay because December is approaching and you still haven’t received yours, or because you recently resigned and want to know what you’re entitled to, Philippine law sets a clear rule. Employers in the private sector must release the 13th month pay not later than December 24 of every year. This article explains exactly what the law requires, who qualifies, how the amount is calculated (including when you worked only part of the year), what happens if you left your job, and the practical steps you can take if payment is delayed.

What Is the 13th Month Pay?

The 13th month pay is a mandatory additional benefit equivalent to one-twelfth (1/12) of an employee’s total basic salary earned during the calendar year. It is not a bonus or gift from the employer. It is a statutory right designed to help workers cope with year-end expenses and the effects of inflation. Many companies release it earlier — sometimes as early as November or in two installments — but the law fixes the latest possible date.

Legal Basis

The requirement comes from Presidential Decree No. 851 issued on December 16, 1975. Section 1 originally required employers to pay a 13th-month pay not later than December 24 to employees earning not more than ₱1,000 monthly. The Rules and Regulations Implementing PD 851, and subsequent clarifications, modified this to cover all rank-and-file employees in the private sector, regardless of salary level or position title.

You can read the full text of Presidential Decree No. 851 on LawPhil. The Department of Labor and Employment (DOLE) continues to issue reminders every year reinforcing the December 24 deadline.

Who Is Entitled to 13th Month Pay?

You qualify if you meet these conditions:

You are a rank-and-file employee (not a managerial employee who has the power to lay down policies or effectively recommend hiring, firing, or discipline).
You worked for at least one month (or 30 calendar days) during the calendar year, including periods of paid or unpaid leave, holidays, and rest days.
Your employer is in the private sector.

Exceptions (employers generally not covered):

Government agencies and most government-owned and controlled corporations.
Household helpers and personal service workers.
Employers already paying a 13th-month pay or its equivalent when PD 851 took effect.
Workers paid purely on commission, boundary, or task basis (except piece-rate workers).
Distressed employers who obtained prior exemption from the DOLE Secretary.

Even probationary, casual, project, seasonal, and fixed-term rank-and-file employees are covered as long as they meet the one-month service requirement. Foreign nationals working as rank-and-file employees for private companies in the Philippines enjoy the same rights.

How Is the 13th Month Pay Computed?

The formula is straightforward:

13th Month Pay = Total Basic Salary Earned in the Calendar Year ÷ 12

Basic salary includes all earnings paid for services rendered. It generally excludes:

Cost-of-living allowance (COLA) unless integrated into basic pay by company policy or agreement.
Overtime pay, night shift differential, holiday pay, and premium pay.
Profit-sharing, unused leave credits, and most allowances that were not part of basic salary in 1975.

Sales commissions are included when they form a regular and substantial part of the employee’s earnings.

Examples:

Monthly basic salary of ₱18,000, worked the full year → ₱18,000 × 12 ÷ 12 = ₱18,000.
Same salary, worked only 7 months → ₱18,000 × 7 ÷ 12 = ₱10,500.
Employee with variable commissions who earned ₱240,000 in basic pay (regular wage + qualifying commissions) over 10 months → ₱240,000 ÷ 12 = ₱20,000.

The Supreme Court has consistently upheld pro-ration for partial-year service (see Central Azucarera de Tarlac v. Central Azucarera de Tarlac Labor Union-NLU, G.R. No. 188949, 26 July 2010).

The Mandatory Deadline: December 24

Under PD 851 and its implementing rules, the 13th month pay must be paid not later than December 24 of every year. This date was chosen so workers have the money in time for the Christmas season.

Employers have flexibility:

They may release the full amount earlier.
They may split it: one-half before the opening of the regular school year and the remaining half on or before December 24.
In unionized companies, the payment schedule can be set through a collective bargaining agreement.

The law does not allow employers to delay payment past December 24 because of cash-flow problems or internal policies. The obligation is fixed.

What If You Resigned, Retired, or Were Terminated Before December?

You are still entitled to a pro-rated 13th month pay based on the basic salary you actually earned from the start of the year (or your hiring date) up to your last day of work, provided you rendered at least 30 calendar days of service.

This pro-rated amount must be included in your final pay. Employers cannot refuse it simply because you are no longer employed on December 24. Withholding it violates the law. Most companies process final pay (including the pro-rated 13th month) within 30 days after your last working day or after you complete the exit clearance process.

What If Your Employer Does Not Release It on Time?

If December 24 passes and you have not received your 13th month pay (or the correct pro-rated amount), take these practical steps:

Send a written request (email or formal letter) to your employer or HR, stating the legal basis (PD 851) and the exact amount you believe is due. Keep copies and proof of sending.
If there is no satisfactory response within a reasonable time (usually 5–10 days), file a complaint with the nearest DOLE Regional Office. DOLE offers the Single Entry Approach (SEnA) for quick mediation at no cost.
For larger or disputed claims, you may file a case with the National Labor Relations Commission (NLRC). Money claims generally prescribe after three years, but it is best to act promptly.

DOLE can also conduct workplace inspections. Employers who repeatedly violate the rule may face administrative sanctions in addition to paying what is owed.

Common Pitfalls and Real-Life Scenarios

Many employees face these situations:

The company says “We’ll release it in January when we have funds.” — This is not allowed. The deadline is mandatory.
The employer claims the 13th month pay is “already included in your bonus.” — Only if the bonus is at least equal to the required 1/12 amount; otherwise, the difference must still be paid.
A resigned employee is told “Company policy says only active employees on December 24 get it.” — Company policy cannot override the law. You are entitled to the pro-rated share.
Disputes over what counts as “basic salary,” especially with commissions or allowances. Keep your payslips and employment contract — they show the rate and what was actually paid as basic.

Part-time employees and those with multiple private-sector jobs are entitled to proportionate shares from each employer.

Frequently Asked Questions

When is the exact deadline for 13th month pay in the Philippines?
It must be released on or before December 24 of every year.

Can my employer pay the 13th month pay after December 24?
No. The law requires payment not later than that date. Late payment can be the subject of a DOLE complaint.

Am I still entitled if I resigned in September or October?
Yes. You receive a pro-rated amount based on the basic salary you earned during the months you worked. It should be included in your final pay.

How is 13th month pay computed for project or seasonal workers?
The same formula applies: total basic salary earned during the calendar year divided by 12, as long as you worked at least 30 calendar days.

Can the 13th month pay be given in installments?
Yes. Employers may split it into two parts (one before school opening and the balance by December 24) or follow a schedule agreed in a collective bargaining agreement.

Is the 13th month pay taxable?
It is generally exempt from income tax up to a certain ceiling set by BIR rules (currently part of the ₱90,000 combined exemption for 13th month pay and other benefits). Any amount above the exempt limit is taxable.

Do government employees receive 13th month pay?
Most national and local government employees receive a 13th month pay or equivalent under separate rules, but PD 851 itself primarily covers the private sector.

What documents should I prepare if I need to claim unpaid 13th month pay?
Keep your payslips, employment contract or appointment paper, and any written communications with HR. These help establish your basic salary rate and period of employment.

Can my employer substitute another benefit for the 13th month pay?
No. The law prohibits substitution. If the employer already provides an equivalent amount (such as a Christmas bonus of at least 1/12), they do not need to pay extra, but they must still meet the minimum requirement.

Key Takeaways

The legal deadline for releasing 13th month pay is December 24 of every year.
