How to compute 13th month pay in the Philippines (2026)
The formula is simple — total basic salary divided by 12. The edge cases are not. Mid-year hires, resigned employees, maternity differentials, unpaid leave — every scenario with worked examples and DOLE compliance deadlines.

What is 13th month pay?
13th month pay is a mandatory monetary benefit under Presidential Decree No. 851, signed in 1975. It requires all private-sector employers — regardless of size, industry, or business structure — to pay eligible employees an amount equivalent to one-twelfth (1/12) of their total basic salary earned during the calendar year.
It is not a bonus. It is not discretionary. It cannot be withheld, reduced, or offset against advances without legal basis. Under the law, it is a right — and DOLE enforces it.
Who is entitled?
| Entitled | Not entitled |
|---|---|
| All rank-and-file employees in the private sector | Managerial employees — those who manage a department and direct two or more employees |
| Employees who worked at least one month during the calendar year | Government employees (separate benefit applies) |
| Full-time, part-time, probationary, contractual, project-based, seasonal | Employees already receiving an equivalent benefit under CBA — only if equal to or greater |
| Daily-rate and piece-rate workers | |
| Kasambahays (domestic workers) — RA 10361 |
Watch out
Many Philippine companies have extended 13th month pay to managerial employees as longstanding practice. Once established, it becomes a contractual obligation — the employer cannot unilaterally withdraw it without employee consent and potential legal exposure.
The formula
Full-year employee
13th Month Pay = Total Basic Salary Earned (Jan–Dec) ÷ 12
Partial-year employee (mid-year hire, resigned, etc.)
13th Month Pay = Total Basic Salary Actually Earned During the Year ÷ 12
The divisor is always 12 — fixed by law. What changes is the numerator. Do not divide by the number of months worked.
What counts as basic salary?
This is the most common source of error. Basic salary is not total compensation.
| Excluded from computation | Included in computation |
|---|---|
| Overtime pay | Monthly basic salary |
| Night shift differential | Daily rate × days worked (daily-rate employees) |
| Holiday premium pay | Salary during paid leaves (vacation leave, sick leave) |
| Rest day premium | Maternity leave salary differential (RA 11210) |
| Allowances (transport, meal, housing, COLA) | Commission — only if integrated into basic salary by company policy or CBA |
| Performance bonuses, cash gifts, service charges |
On maternity leave
Under RA 11210, the salary differential — the difference between the SSS maternity benefit and the employee's regular salary — is explicitly included as basic salary for 13th month purposes. Many payroll systems do not handle this automatically.
7 worked scenarios
Scenario 1
Full-year employee, fixed monthly rate
Employee earns ₱35,000/month basic salary. Worked January to December 2026 with no unpaid leaves.
Scenario 2
Mid-year hire
Hired July 1, 2026. Monthly basic salary: ₱28,000. No unpaid leaves.
Scenario 3
Employee who resigned before December 24
Earns ₱22,000/month. Worked January–September 2026, resigned September 30.
Must be included in final pay. Under DOLE Labor Advisory No. 06-20, final pay must be released within 30 days from separation.
Scenario 4
Employee with unpaid leaves
Earns ₱40,000/month. Worked all 12 months but took 15 days unpaid leave in March. Daily rate: ₱40,000 ÷ 26 = ₱1,538.46.
Scenario 5
Salary changed mid-year (promotion)
Promoted July 1, 2026. Salary Jan–Jun: ₱30,000. Salary Jul–Dec: ₱38,000.
Scenario 6
Daily-rate employee
Works 6 days/week at ₱750/day. Actual days worked in 2026: 280 days.
Scenario 7
Employee on maternity leave (RA 11210)
Earns ₱45,000/month. Took 105-day maternity leave. SSS benefit: ₱60,000. Employer salary differential: ₱97,500.
Always include the maternity salary differential. Required under RA 11210 — most generic payroll systems miss this.
Tax treatment (TRAIN Law)
Under the TRAIN Law (RA 10963), 13th month pay is tax-exempt up to ₱90,000 — combined with other qualifying benefits in the same calendar year. The ₱90,000 ceiling applies to the total of 13th month pay, Christmas bonus, productivity incentives, and other bonuses of a similar nature.
| Component | Amount |
|---|---|
| 13th month pay | ₱60,000 |
| Christmas bonus | ₱40,000 |
| Total benefits | ₱100,000 |
| Tax-exempt ceiling | ₱90,000 |
| Taxable excess | ₱10,000 |
The ₱10,000 taxable excess is added to December's taxable income and subject to the employee's BIR graduated rate. This must be reflected in BIR Form 2316.
Payment deadlines & DOLE compliance
Common mistakes that lead to DOLE complaints
Including overtime and allowances in the base
Computing 13th month on total compensation rather than basic salary sets a precedent that is difficult to reverse — and may constitute underpayment if you later try to correct it.
Forgetting resigned employees
Pro-rated 13th month must be included in final pay. This is the most common trigger for DOLE complaints against Philippine SMEs.
Dividing by months worked instead of 12
The divisor is always 12 — fixed by law. Using the number of months worked as the denominator is an error that systematically overpays employees.
Missing the maternity salary differential
Explicitly required under RA 11210. The differential between the SSS benefit and full salary is part of basic salary for 13th month computation purposes.
Not accounting for mid-year salary changes
Compute on total actual earnings for the year — not on the current rate annualised. Promotions and salary increases change the numerator.
13th month pay — computed automatically, every scenario covered.
KAMI's payroll module pulls from each employee's actual salary history — pro-rated periods, unpaid leaves, maternity differentials, mid-year salary changes. It flags employees approaching the ₱90,000 tax ceiling, generates the DOLE compliance report, and produces a full audit trail.

Frequently asked questions
Is 13th month pay mandatory for probationary employees?
Yes. Probationary employees who have worked for at least one month are entitled to pro-rated 13th month pay based on their actual basic salary earned.
What if an employee went AWOL?
Employees who go AWOL are still entitled to 13th month pay for the months they actually worked. The employer may deduct outstanding obligations but cannot withhold the benefit outright. Processing may be delayed pending clearance.
Can employers pay 13th month pay earlier than December?
Yes. Many companies release it in June and December, or as a single payment in November. The law sets the deadline — not the earliest payment date.
Is there a 14th month pay law in the Philippines?
No. 14th month pay is entirely discretionary. Some companies pay it voluntarily or by contractual commitment, but there is no statutory obligation under Philippine law.
What is the difference between 13th month pay and final pay?
Final pay is the total amount owed to a separated employee — including unpaid wages, unused leave conversions, and pro-rated 13th month pay. The 13th month component uses the same pro-rated formula.
