What Is 13th Month Pay? The Legal Basis
13th month pay is one of the oldest and most widely recognized mandatory employee benefits in the Philippines. It was created by Presidential Decree No. 851, signed on December 16, 1975, which directed all employers in the private sector to pay their rank-and-file employees a bonus equivalent to one-twelfth of their annual basic salary, released not later than December 24 of every year. The decree was issued at a time of high inflation, and its stated purpose was to help workers cope with the added expenses of the Christmas season. Half a century later, the requirement remains fully in force and is one of the benefits Filipino employees associate most closely with year-end payroll.
The Department of Labor and Employment (DOLE) fleshed out the details of PD 851 through its Revised Guidelines on the Implementation of the 13th Month Pay Law, issued in 1987. These guidelines defined key terms such as "basic salary" and "rank-and-file employee," clarified which employers and workers are covered, and set out how the benefit should be computed and reported. Every year, usually around October or November, DOLE regional and field offices issue a Labor Advisory reminding employers of the December 24 deadline and of their obligation — which applies to every covered employer regardless of company size — to file a report of compliance afterward. For 2026, the computation rules and the ₱90,000 tax-exemption threshold introduced by the TRAIN Law remain unchanged, so the figures used throughout this guide reflect current law.
Who Is Covered — and Who Is Excluded
The general rule is broad: all rank-and-file employees in the private sector are entitled to 13th month pay, regardless of the nature of their employment, as long as they have worked for at least one month during the calendar year. This includes regular, probationary, contractual, project-based, and part-time employees. It also covers employees paid on a piece-rate, task, or commission basis, at least with respect to the fixed or guaranteed wage portion of their pay. A worker does not need to complete a full year of service, nor does she need to still be employed in December, to qualify — one month of service is enough to create a pro-rated entitlement.
The following are generally excluded from the mandatory coverage of PD 851:
- Managerial employees. The Labor Code defines a managerial employee as one whose primary duty is to manage the establishment, or a department or subdivision of it, and who has the authority to hire, transfer, suspend, lay off, recall, discharge, or discipline other employees, or to effectively recommend such actions. Because PD 851 is explicitly framed as a rank-and-file benefit, true managerial employees have no statutory right to a 13th month pay. In practice, however, many companies voluntarily grant managers an equivalent or larger year-end bonus as part of their total compensation package — nothing in the law prevents an employer from being more generous than the minimum it requires.
- Government employees. Workers in national and local government agencies and government-owned or controlled corporations are covered instead by separate rules on a year-end bonus and cash gift funded through the national budget, not by PD 851.
- Kasambahay (domestic workers). Household helpers are covered by their own law, Republic Act No. 10361 (the Domestic Workers Act), which grants an equivalent 13th month benefit under a different set of implementing rules.
- Employees already receiving an equivalent or greater benefit. If an employer already pays a bonus scheme — such as a combined mid-year and year-end bonus — that is at least equal to one-twelfth of the employee's annual basic salary, it may be treated as compliance with PD 851 without requiring a separate, additional payment, provided the existing benefit is clearly not lower than what the law requires.
One point of confusion worth clearing up: supervisory employees who do not meet the strict legal test for "managerial employee" (for example, those who merely recommend rather than independently decide on disciplinary matters) are still considered rank-and-file for purposes of PD 851 and remain covered by the mandatory 13th month pay.
The Exact Computation Formula
The formula prescribed by DOLE is simple in principle:
13th Month Pay = Total Basic Salary Earned During the Calendar Year ÷ 12
The key term to understand is "basic salary." Under the DOLE guidelines, basic salary means all remuneration the employee actually earned for services rendered, excluding allowances and monetary benefits that are not integrated into the basic pay. In practice, the following are generally excluded from the 13th month pay computation unless a company policy or collective bargaining agreement expressly integrates them into basic salary:
- Overtime pay and premium pay for rest days or holidays
- Night shift differential
- Cost-of-living allowances (COLA) and other fixed allowances
- Cash value of unused service incentive leave or other monetized leave credits
- Profit-sharing payments, stock options, and other discretionary fringe benefits
Because the formula runs off basic salary actually earned, anything that reduces an employee's basic pay during the year — such as unpaid leave or absences without pay — will also reduce the 13th month pay, even if the employee remained on the payroll for all 12 months.
Worked Example 1: A Full Year of Service
Maria is hired on January 1 and works the entire year without any unpaid absences. Her monthly basic salary is ₱25,000.
- Total basic salary earned = ₱25,000 × 12 months = ₱300,000
- 13th month pay = ₱300,000 ÷ 12 = ₱25,000
Because Maria's basic salary was constant every month, her 13th month pay simply equals one month's basic salary — a helpful shortcut for employees whose pay didn't change during the year.
Worked Example 2: A Year With Unpaid Leave
Juan's monthly basic salary is ₱30,000. In August, he took 10 days of unpaid leave, which reduced his basic pay for that month to ₱20,000. Every other month he received his full ₱30,000.
- Basic salary earned, 11 regular months = ₱30,000 × 11 = ₱330,000
- Basic salary earned in August = ₱20,000
- Total basic salary earned = ₱330,000 + ₱20,000 = ₱350,000
- 13th month pay = ₱350,000 ÷ 12 = ₱29,166.67
Notice that Juan's 13th month pay comes out slightly lower than his nominal monthly salary, because the unpaid days reduced the total basic salary he actually earned for the year — the divisor is always 12, regardless of how much was actually earned.
The ₱90,000 Tax-Exemption Threshold
Under Section 32(B)(7)(e) of the Tax Code, as amended by the TRAIN Law (Republic Act No. 10963), 13th month pay is not taxed on its own — it is pooled together with certain "other benefits" an employee receives during the year, such as a Christmas bonus, cash gifts, mid-year bonus, productivity incentives, and similar additional compensation. The combined total of 13th month pay plus these other benefits is exempt from income tax up to ₱90,000 per year. Any amount in excess of ₱90,000 is added to the employee's taxable compensation income for the year and subjected to withholding tax under the graduated BIR TRAIN Law brackets, typically trued up in the December payroll run or reflected in the year-end BIR Form 2316.
Worked Example: Exceeding the Threshold
Anna's monthly basic salary is ₱70,000, and she works the full year, so her 13th month pay alone would be ₱70,000 — comfortably under the cap. However, her employer also gives her a ₱30,000 mid-year bonus and a ₱15,000 company anniversary bonus, both of which count as "other benefits" for tax purposes.
- 13th month pay = ₱70,000
- Mid-year bonus = ₱30,000
- Anniversary bonus = ₱15,000
- Total "13th month pay and other benefits" = ₱115,000
- Tax-exempt portion (capped) = ₱90,000
- Taxable excess = ₱115,000 − ₱90,000 = ₱25,000
That ₱25,000 excess is added to Anna's other taxable compensation income for the year and taxed according to the BIR's graduated brackets — it is not taxed as a flat percentage of the excess, but combined with her regular salary in computing her total annual tax due. This example shows why an employee's 13th month pay can look tax-exempt in isolation, yet still trigger additional withholding once other bonuses are added on top.
13th Month Pay and Taxability at a Glance
| Monthly Basic Salary | Annual Basic (12 months) | 13th Month Pay | Tax-Exempt | Taxable Excess |
|---|---|---|---|---|
| ₱15,000 | ₱180,000 | ₱15,000 | ₱15,000 | ₱0 |
| ₱25,000 | ₱300,000 | ₱25,000 | ₱25,000 | ₱0 |
| ₱50,000 | ₱600,000 | ₱50,000 | ₱50,000 | ₱0 |
| ₱90,000 | ₱1,080,000 | ₱90,000 | ₱90,000 | ₱0 |
| ₱100,000 | ₱1,200,000 | ₱100,000 | ₱90,000 | ₱10,000 |
| ₱150,000 | ₱1,800,000 | ₱150,000 | ₱90,000 | ₱60,000 |
As the table shows, the 13th month pay of most rank-and-file employees in the Philippines — even fairly well-compensated ones — remains entirely tax-exempt on its own. It is only once monthly basic salary climbs past roughly ₱90,000, or once other bonuses are stacked on top, that any part of the benefit becomes subject to withholding tax.
When 13th Month Pay Must Be Paid
PD 851 is explicit: 13th month pay must be paid not later than December 24 of every year. Employers are free to release it earlier, and many do — a common practice is to split the benefit into two payouts, for instance half in May or June and the remaining half before December 24, or to pay the full amount in a single lump sum sometime in November or early December. What the law does not allow is delaying full payment beyond December 24, regardless of the employer's cash flow situation, unless DOLE has formally granted a distressed employer an exemption or deferred schedule, which is uncommon and requires a specific application and approval.
Every covered employer — regardless of company size — is required under Section 8 of PD 851 to submit a compliance report confirming that 13th month pay has been paid, not later than January 15 of the following year. DOLE now administers this filing through its Online Compliance Portal, where the employer indicates the establishment's name and address, total employment, the number of workers who received the benefit, and the total amount paid out. Failure to pay on time can expose an employer to a DOLE labor inspection, an order to pay the benefit plus possible administrative fines, and in cases of willful or repeated refusal, potential liability under the penal provisions of the Labor Code. Employees who do not receive their 13th month pay by December 24 may file a request for assistance or a formal complaint with the nearest DOLE field office.
Pro-Ration for Employees Who Resigned or Were Hired Mid-Year
A common misconception is that an employee must complete a full year, or still be employed in December, to receive 13th month pay. This is incorrect. Because the benefit is computed strictly from basic salary actually earned, any employee who has rendered at least one month of service during the calendar year is entitled to a proportionate, or pro-rated, 13th month pay — whether they were hired partway through the year, resigned before December, or were terminated for a valid cause.
Worked Example: A Mid-Year Resignation
Mark is hired on March 1 with a monthly basic salary of ₱30,000, and resigns effective November 15 of the same year.
- Full months worked at full pay: March through October = 8 months × ₱30,000 = ₱240,000
- Partial month: November 1–15 (half of the month) = ₱15,000
- Total basic salary earned = ₱240,000 + ₱15,000 = ₱255,000
- 13th month pay = ₱255,000 ÷ 12 = ₱21,250
Mark's pro-rated 13th month pay of ₱21,250 forms part of his final pay and does not need to wait until the December 24 deadline — it should be released together with his other final pay items (unpaid salary, unused leave conversion, and any other amounts due) within the timeframe recommended by DOLE for final pay, generally within 30 days from the date of separation. The same logic applies symmetrically to an employee hired partway through the year: someone hired on September 1 and still employed on December 31 would have their 13th month pay computed only on the basic salary earned from September to December, divided by 12 — not divided by 4, since the divisor under the formula is always 12 regardless of how many months were actually worked.
Frequently Asked Questions
Is 13th month pay mandatory in the Philippines?
Yes. Under Presidential Decree No. 851, every private-sector employer must pay its rank-and-file employees a 13th month pay on or before December 24 of each year, as long as the employee has worked at least one month during the calendar year. It is not a discretionary bonus — it is a legally mandated benefit.
Do probationary, contractual, or part-time employees get 13th month pay?
Yes. Coverage under PD 851 depends on being a rank-and-file employee who has rendered at least one month of service, not on employment status. Probationary, contractual, project-based, and part-time rank-and-file employees are all entitled to a pro-rated 13th month pay based on the basic salary they actually earned.
Are managers entitled to 13th month pay?
Not under PD 851 — the law's mandatory coverage is limited to rank-and-file employees, and true managerial employees (those with authority to hire, discipline, or effectively recommend such actions) are excluded. In practice, many employers voluntarily give managers an equivalent or larger year-end bonus, but this is a company policy choice rather than a legal requirement.
Is 13th month pay the same as a Christmas bonus?
No. 13th month pay is a mandatory statutory benefit computed as one-twelfth of the basic salary earned during the year. A Christmas bonus is typically a separate, discretionary benefit an employer chooses to give on top of it. For tax purposes, however, both are pooled together with other similar benefits under the same ₱90,000 tax-exempt cap.
Do resigned or terminated employees still get 13th month pay?
Yes. An employee who separates from a company before December — whether through resignation, end of contract, or termination for cause — is still entitled to a pro-rated 13th month pay based on the basic salary actually earned up to the last day worked. This amount should be included in the employee's final pay.
Is my 13th month pay taxable?
Generally no. Under the TRAIN Law, 13th month pay combined with other similar benefits (mid-year bonus, cash gifts, and productivity incentives) is exempt from income tax up to ₱90,000 per year. Only the portion of the combined total that exceeds ₱90,000 becomes part of your taxable compensation income and is subject to withholding tax.
What happens if my employer doesn't pay by December 24?
You may file a request for assistance or a formal complaint with your nearest DOLE regional or field office. DOLE can conduct a labor inspection, order the employer to pay the benefit with possible administrative fines, and in cases of willful or repeated non-compliance, the employer may face further liability under the Labor Code.
Does 13th month pay include overtime, allowances, or unused leave conversions?
No, not under the default DOLE rule. The computation is based strictly on basic salary earned for actual work rendered. Overtime pay, holiday and rest-day premiums, night shift differential, fixed allowances, and monetized unused leave are excluded unless a company policy or collective bargaining agreement expressly integrates them into the definition of basic salary.
