For 13th month pay in the Philippines, basic salary generally means the pay you actually earned for your regular work during the calendar year. It is not always the same as your gross pay, take-home pay, or the amount shown at the top of your payslip. Overtime, night shift differential, holiday premiums, allowances, bonuses, and other extra benefits are usually excluded unless your contract, company policy, collective bargaining agreement, or long-standing company practice treats them as part of your regular basic salary.
This matters because the legal formula is simple, but payroll disputes usually happen in the details:
13th month pay = total basic salary earned during the calendar year ÷ 12
So if your employer computed your 13th month pay lower than expected, the first thing to check is not only your monthly rate, but what payroll included or excluded as “basic salary.”
What “Basic Salary” Means for 13th Month Pay
Under Presidential Decree No. 851, commonly called the 13th Month Pay Law, the minimum 13th month pay is one-twelfth of the employee’s basic salary earned within the calendar year.
The rules implementing PD 851 explain that “basic salary” includes the earnings paid by the employer to the employee for services rendered. In ordinary terms, this is your regular pay for doing your job.
It does not normally include extra payments that are not part of your regular basic salary, such as:
- overtime pay
- premium pay
- night shift differential
- holiday pay premiums
- cost-of-living allowance, if separately stated
- cash conversion of unused vacation or sick leave
- profit-sharing payments
- discretionary bonuses
- commissions that are true incentives and not part of the wage structure
- transportation, meal, communication, or rice allowances, unless integrated into basic pay
The important practical point is this: the label used by the employer is not always controlling. If an amount is consistently treated as part of regular salary, or is integrated into the employee’s basic pay by contract, company policy, CBA, or established company practice, it may have to be included.
Legal Basis: Who Is Entitled to 13th Month Pay?
The current rule is that rank-and-file employees in the private sector are entitled to 13th month pay if they worked for at least one month during the calendar year.
This applies regardless of:
- whether the employee is regular, probationary, project-based, seasonal, contractual, or part-time
- the employee’s position title, as long as the employee is legally rank-and-file
- whether wages are paid daily, weekly, semi-monthly, monthly, by piece rate, or under another wage method
- whether the employee resigned, was terminated, or separated before December, as long as they earned basic salary during the year
The original PD 851 had a salary ceiling, but later rules removed that ceiling for rank-and-file employees. The Revised Guidelines on the Implementation of the 13th Month Pay Law state that all rank-and-file employees are entitled regardless of the amount of monthly basic salary.
Rank-and-File vs. Managerial Employees
A rank-and-file employee is generally someone who does not have real management authority to lay down and execute management policies or to hire, transfer, suspend, lay off, recall, discharge, assign, or discipline employees.
A job title like “manager,” “officer,” “team lead,” or “supervisor” does not automatically remove 13th month pay entitlement. What matters is the employee’s actual authority and duties.
For example:
| Employee situation | Likely treatment |
|---|---|
| “Sales Manager” with no hiring, firing, or policy-making authority | May still be rank-and-file or supervisory, depending on facts |
| Store branch manager who controls staffing, discipline, and operations | May be managerial |
| Team lead who only monitors attendance and reports to HR | Title alone is not enough to classify as managerial |
| Supervisor who effectively recommends disciplinary actions using independent judgment | May be supervisory, but not necessarily managerial |
In many companies, even managerial employees receive a 13th month equivalent as a company benefit. But the strict statutory entitlement under PD 851 is for rank-and-file employees.
What Is Included in Basic Salary?
The safest way to understand basic salary is to ask: Was this amount paid as regular compensation for the employee’s normal work?
| Pay item | Included in 13th month basic salary? | Practical note |
|---|---|---|
| Monthly basic pay | Yes | The usual basis for monthly-paid employees |
| Daily wage for days actually worked | Yes | Add all regular daily wages earned during the year |
| Paid leave with pay | Usually yes | Because the employee still received regular salary |
| Salary during paid regular holidays for monthly-paid employees | Usually yes | This is part of regular paid salary, not an extra premium |
| Piece-rate earnings | Yes, for covered workers | Use total earnings from output or production |
| Fixed or guaranteed wage | Yes | Included as regular pay |
| Salary differential paid by employer during maternity leave | Yes | DOLE guidance treats this as part of basic salary for 13th month computation |
| Commission forming part of wage structure | May be yes | Depends on how and why it is paid |
Example: Full-Year Monthly Employee
Ana earns a basic salary of ₱25,000 per month and worked the entire year with no unpaid absences.
| Month | Basic salary earned |
|---|---|
| January to December | ₱300,000 |
Computation:
₱300,000 ÷ 12 = ₱25,000
Ana’s minimum 13th month pay is ₱25,000.
Example: Employee Hired Mid-Year
Ben was hired on July 1 with a monthly basic salary of ₱30,000.
| Period worked | Basic salary earned |
|---|---|
| July to December | ₱180,000 |
Computation:
₱180,000 ÷ 12 = ₱15,000
Ben does not get the full ₱30,000 because he did not earn a full year of basic salary. He gets the proportionate 13th month pay of ₱15,000.
Example: Salary Increase During the Year
Cara earned ₱25,000 per month from January to June, then ₱30,000 per month from July to December.
| Period | Basic salary earned |
|---|---|
| January to June: ₱25,000 × 6 | ₱150,000 |
| July to December: ₱30,000 × 6 | ₱180,000 |
| Total basic salary earned | ₱330,000 |
Computation:
₱330,000 ÷ 12 = ₱27,500
Cara’s 13th month pay is ₱27,500, not simply her latest salary of ₱30,000.
What Is Excluded From Basic Salary?
The usual excluded items are payments that are extra, conditional, or not part of the employee’s regular wage for ordinary work.
| Pay item | Excluded? | Why |
|---|---|---|
| Overtime pay | Yes | Extra pay for work beyond normal hours |
| Night shift differential | Yes | Additional statutory premium |
| Rest day premium | Yes | Additional pay for rest day work |
| Special holiday premium | Yes | Additional premium, not basic salary |
| Regular holiday premium or extra holiday pay | Yes | The premium portion is not basic salary |
| Cash conversion of unused leave | Yes | Paid because leave was unused, not for current services rendered |
| COLA separately stated | Usually yes | Not basic salary unless integrated |
| Transportation, meal, rice, or communication allowance | Usually yes | Excluded unless integrated into basic pay |
| Performance bonus | Usually yes | Generally separate from basic salary |
| Profit-sharing | Yes | Not regular salary |
| SSS maternity benefit | Yes, excluded | Paid by SSS, not employer basic salary |
Be careful with holiday pay. For a monthly-paid employee who receives the same monthly salary even when a regular holiday occurs, that monthly salary remains part of basic salary. What is excluded is the extra holiday premium or additional holiday pay, not the ordinary monthly salary itself.
Commissions: When Are They Included?
Commissions are one of the most common sources of confusion.
The Supreme Court has treated commissions differently depending on their nature.
In Boie-Takeda Chemicals, Inc. v. De la Serna, G.R. No. 92174, December 10, 1993, the Court recognized that 13th month pay under PD 851 is based on basic salary, and that commissions that are not part of basic salary are excluded.
But in Philippine Duplicators, Inc. v. NLRC, G.R. No. 110068, February 15, 1995, the Court held that certain sales commissions formed part of basic salary because they were directly tied to the work performed and were part of the salary structure.
In Philippine Agricultural Commercial and Industrial Workers Union v. NLRC, G.R. No. 107994, August 14, 1995, the Court also emphasized that employees receiving a guaranteed wage plus commission may be entitled to 13th month pay based on their total earnings, depending on how the compensation system actually works.
Practical Rule for Commissions
Ask these questions:
- Is the commission a direct payment for the employee’s regular work output?
- Is it a predetermined part of the wage structure?
- Is it regularly earned as part of how the employee is compensated?
- Does the employee have a guaranteed wage plus commission arrangement?
- Is the “commission” really just an incentive, bonus, or profit-sharing item?
If the commission is part of the wage structure for services rendered, it may be included. If it is merely an incentive or bonus outside basic salary, it may be excluded.
How to Compute 13th Month Pay Step by Step
Use this practical process before raising a payroll dispute.
Get your payslips for the calendar year. Use January to December, or your employment period if you were hired, resigned, or separated during the year.
Identify only the basic salary earned. Exclude overtime, premiums, night differential, allowances, bonuses, and other non-basic items unless they are integrated into your basic pay.
Add the basic salary actually earned. If you had unpaid absences or unpaid leave, your total basic salary earned may be lower.
Divide by 12. Do this even if you worked for less than 12 months. The formula is still total basic salary earned during the calendar year divided by 12.
Compare with what was paid. If there is a difference, ask payroll or HR for a written breakdown.
Check company policy, contract, or CBA. Some employers give more than the statutory minimum. A more favorable benefit may become enforceable if it is in a contract, CBA, policy, or long-standing practice.
Common Real-Life Scenarios
You Had Unpaid Absences
If you are “no work, no pay,” unpaid absences reduce your basic salary earned. Since 13th month pay is based on actual basic salary earned, the 13th month pay may also be lower.
Example:
| Item | Amount |
|---|---|
| Monthly basic salary | ₱24,000 |
| Total basic salary that could have been earned for full year | ₱288,000 |
| Less unpaid absences deducted from salary | ₱8,000 |
| Actual basic salary earned | ₱280,000 |
| 13th month pay | ₱23,333.33 |
Computation:
₱280,000 ÷ 12 = ₱23,333.33
You Were on Paid Leave
If your leave was paid and your regular salary was not reduced, the paid salary is generally included because it was still paid as salary.
You Were on Maternity Leave
Maternity benefits from SSS are not basic salary because they are paid by SSS. However, the salary differential paid by the employer under the Expanded Maternity Leave Law rules is treated by DOLE as part of basic salary for computing 13th month pay. See DOLE’s Department Advisory No. 01-19 on maternity leave salary differential.
You Resigned Before December
A resigned employee is still entitled to proportionate 13th month pay.
Example:
| Item | Amount |
|---|---|
| Monthly basic salary | ₱20,000 |
| Worked from January to September | 9 months |
| Total basic salary earned | ₱180,000 |
| 13th month pay | ₱15,000 |
Computation:
₱180,000 ÷ 12 = ₱15,000
The employer should not deny the benefit simply because the employee did not stay until December.
You Were Terminated
Termination does not automatically remove the right to earned 13th month pay. If you earned basic salary during the year, the proportionate 13th month pay should be included in your final pay, subject to lawful deductions and clearance rules.
Under DOLE Labor Advisory No. 06-20 on final pay, final pay should generally be released within 30 days from separation or termination, unless a more favorable company policy, contract, or agreement applies.
You Are Paid Daily
For daily-paid employees, add the regular daily wages actually earned during the year, then divide by 12.
Example:
| Item | Amount |
|---|---|
| Daily basic wage | ₱700 |
| Days actually paid during the year | 280 |
| Total basic salary earned | ₱196,000 |
| 13th month pay | ₱16,333.33 |
Computation:
₱196,000 ÷ 12 = ₱16,333.33
You Are Paid by Piece Rate
Covered piece-rate workers are entitled to 13th month pay. The basis is usually the total earnings from production or output during the year, divided by 12.
Example:
| Item | Amount |
|---|---|
| Total piece-rate earnings for the year | ₱240,000 |
| 13th month pay | ₱20,000 |
Computation:
₱240,000 ÷ 12 = ₱20,000
You Have More Than One Employer
If you work for two private employers, each employer computes 13th month pay based only on the basic salary you earned from that employer.
A government employee who also works part-time for a private employer may be entitled to 13th month pay from the private employer for that private employment.
You Are a Kasambahay
Domestic workers, or kasambahays, have a specific law: Republic Act No. 10361, the Domestic Workers Act or Batas Kasambahay. Section 25 states that a domestic worker is entitled to 13th month pay as provided by law.
For a kasambahay, the practical computation is also based on total basic salary earned during the calendar year divided by 12, provided the kasambahay rendered at least one month of service.
13th Month Pay vs. Christmas Bonus
13th month pay is mandatory for covered employees. A Christmas bonus is usually voluntary unless it is required by:
- employment contract
- company policy
- collective bargaining agreement
- long-standing and consistent company practice
- written employer commitment
| Benefit | Mandatory? | Basis |
|---|---|---|
| 13th month pay | Yes, for covered employees | Law |
| Christmas bonus | Usually no | Employer policy, contract, CBA, or practice |
| 14th month pay | Usually no | Unless required by policy, contract, CBA, or practice |
| Performance bonus | Depends | Usually policy-based or discretionary |
An employer cannot replace the legal 13th month pay with a vague “bonus” unless the payment clearly satisfies the legal equivalent required by PD 851 and its rules.
When Should 13th Month Pay Be Paid?
The statutory deadline is not later than December 24 of every year.
Employers may pay it in installments, such as half in June and half in December, as long as the full legally required amount is paid by December 24.
DOLE advisories have also reminded employers that no application for exemption or deferment is allowed for 13th month pay.
Employers are required to submit compliance reports through the DOLE Establishment Report System by the required deadline, commonly in January of the following year, as stated in DOLE’s annual 13th month pay advisories.
Is 13th Month Pay Taxable?
For tax purposes, 13th month pay and other benefits are generally excluded from taxable income up to the statutory ceiling.
Under the TRAIN Law, Republic Act No. 10963, the tax-exempt ceiling for 13th month pay and other benefits is ₱90,000. The BIR’s withholding tax tools also reflect that amounts above ₱90,000 may be taxable as compensation income.
This ₱90,000 ceiling is not only for 13th month pay. It usually covers the combined total of 13th month pay and other benefits such as bonuses and incentives that fall under the same tax category.
Example:
| Item | Amount |
|---|---|
| 13th month pay | ₱80,000 |
| Christmas bonus | ₱20,000 |
| Total | ₱100,000 |
| Tax-exempt portion | ₱90,000 |
| Potential taxable excess | ₱10,000 |
What to Do If Your 13th Month Pay Was Undercomputed
Before filing a complaint, it is often useful to request a written breakdown. Many errors come from payroll classification, unpaid absences, wrong hire date, omitted salary adjustment, or confusion between gross pay and basic pay.
Step-by-Step Practical Guide
Secure your documents. Gather your employment contract, appointment letter, payslips, payroll records, company handbook, salary increase notices, and resignation or termination documents.
Prepare your own computation. List your basic salary earned per month and divide the total by 12.
Ask HR or payroll for a breakdown. Ask which items were included and excluded. Keep the request polite and written, such as by email or official HR ticket.
Check whether allowances were integrated into salary. If an allowance was always treated as part of basic pay, ask payroll why it was excluded.
Check whether commissions are wage-based or incentive-based. If commissions are part of the regular wage structure, cite the relevant Supreme Court rulings.
If unresolved, consider DOLE’s Single Entry Approach. The Single Entry Approach, or SEnA, is a mandatory conciliation-mediation process for many labor issues. It is designed to resolve disputes quickly without immediately going through full litigation.
File with the proper DOLE office if necessary. Usually, this is the DOLE Regional, Provincial, or Field Office covering the workplace.
If the case includes illegal dismissal or larger employment claims, it may go to the NLRC. The National Labor Relations Commission handles labor cases such as illegal dismissal and money claims connected with employer-employee disputes.
Documents Usually Helpful for a DOLE or NLRC Claim
| Document | Why it helps |
|---|---|
| Employment contract or job offer | Shows agreed basic salary and benefits |
| Payslips | Shows actual salary, deductions, and pay items |
| Payroll summary or BIR Form 2316 | Helps prove annual compensation |
| Time records or attendance logs | Helps explain unpaid absences or work days |
| Resignation or termination letter | Shows separation date |
| Company handbook or policy | May show more favorable benefits |
| CBA, if unionized | May contain better 13th month or bonus provisions |
| HR emails or announcements | May show company practice or commitments |
Practical Issues for Foreigners and Overseas Filipinos
Foreigners working in the Philippines for a private-sector employer are generally covered by Philippine labor standards if there is an employer-employee relationship in the Philippines, subject to the terms of their work authorization and employment documents.
Foreign-owned companies operating in the Philippines are also expected to comply with Philippine labor laws for employees in the Philippines. The fact that the parent company is abroad does not automatically remove Philippine labor standards obligations.
For Filipinos working abroad, the answer depends on the governing contract, country of employment, employer, and applicable overseas employment rules. A Filipino employee working abroad is not automatically covered by Philippine 13th month pay rules in the same way as a private employee working in the Philippines, unless the employment contract, applicable law, or deployment terms provide for it.
For expats employing a kasambahay in the Philippines, RA 10361 applies. A household employer’s foreign nationality does not excuse non-payment of the kasambahay’s statutory benefits.
Frequently Asked Questions
What is basic salary for 13th month pay in the Philippines?
Basic salary is the regular pay earned by an employee for services rendered during the calendar year. It generally excludes overtime, night differential, holiday premiums, allowances, bonuses, and other non-basic benefits unless they are integrated into regular basic salary.
Is 13th month pay based on gross salary or basic salary?
It is based on basic salary earned, not gross salary. Gross salary may include overtime, allowances, premiums, and bonuses that are usually excluded from 13th month pay computation.
Are allowances included in 13th month pay?
Usually, no. Transportation, meal, rice, communication, and similar allowances are generally excluded if they are separate from basic salary. They may be included if they are integrated into basic pay by contract, policy, CBA, or established company practice.
Is overtime included in 13th month pay?
No. Overtime pay is expressly excluded from the usual computation of 13th month pay because it is additional compensation for work beyond normal hours, not basic salary.
Are commissions included in 13th month pay?
It depends. If the commission is part of the employee’s wage structure and is direct compensation for services rendered, it may be included. If it is a separate incentive, bonus, or profit-sharing payment, it may be excluded.
Do resigned employees get 13th month pay?
Yes. A resigned employee is entitled to proportionate 13th month pay based on the total basic salary earned during the calendar year up to the resignation date.
Do probationary employees get 13th month pay?
Yes, if they are rank-and-file employees in the private sector and worked for at least one month during the calendar year. Regularization is not required for entitlement.
Is 13th month pay the same as a Christmas bonus?
No. 13th month pay is mandatory for covered employees. A Christmas bonus is usually voluntary unless required by contract, company policy, CBA, or established company practice.
Can an employer pay 13th month pay after December 24?
The legal deadline is not later than December 24. Late payment may expose the employer to a labor standards complaint.
Can an employer deduct cash advances or loans from 13th month pay?
Lawful and authorized deductions may be allowed, but employers should be careful. Unauthorized withholding of wages and benefits can violate the Labor Code. If deductions are made, the employee should ask for a written breakdown showing the legal or agreed basis.
Key Takeaways
- Basic salary for 13th month pay means regular salary earned for services rendered.
- The formula is: total basic salary earned during the calendar year ÷ 12.
- Overtime, holiday premiums, night differential, allowances, bonuses, and unused leave conversions are usually excluded.
- Allowances or commissions may be included if they are integrated into basic salary or form part of the wage structure.
- Resigned, terminated, probationary, project-based, part-time, daily-paid, and piece-rate rank-and-file employees may still be entitled if they worked at least one month.
- The legal deadline for payment is December 24.
- If the computation looks wrong, request a payroll breakdown first, then consider DOLE SEnA or the appropriate labor complaint process if the issue remains unresolved.
