13th Month Pay Calculator Philippines
Compute 13th month pay under Presidential Decree No. 851, including prorated amounts for partial years and the ₱90,000 tax-exempt ceiling.
How to Compute 13th Month Pay
Presidential Decree No. 851 sets one formula: total basic salary earned during the calendar year, divided by 12. Nothing about the divisor changes for employees who joined late or resigned early. A shorter year produces a smaller total to divide, which is what makes the amount prorate itself automatically.
A worked example makes the proration obvious. An employee on ₱20,000 a month who started in July has earned ₱120,000 in basic salary by December. Divided by 12, the 13th month pay is ₱10,000. Dividing by six instead would give ₱20,000, a full month of salary the employee has not accrued, and it is the single most common computation error in Philippine payroll.
What Counts as Basic Salary
The DOLE Handbook draws a firm line between basic salary and everything layered on top of it. Premium payments and allowances stay out of the computation, which is why a heavily incentivized employee can receive a 13th month pay that looks small next to their actual annual earnings.
| Pay Component | Included? |
|---|---|
| Basic monthly pay | Yes |
| Maternity leave salary differential | Yes |
| Overtime pay | No |
| Night shift differential | No |
| Holiday pay and rest day premium | No |
| Cost of living allowance (COLA) | No |
| Cash value of unused leave credits | No |
| SSS maternity benefit | No |
One exception overrides the whole table. Where a collective bargaining agreement, company policy, or established practice treats any of these as part of basic salary, they must be included. A company that has folded allowances into basic pay for years cannot quietly strip them out at year end, since the rule against diminution of benefits in PD 851 blocks that.
Who Is Eligible for 13th Month Pay
Coverage is deliberately broad. Every rank-and-file employee in the private sector qualifies after working at least one month during the calendar year, whatever their designation or employment status. Probationary, project-based, fixed-term, seasonal, and piece-rate workers are all included. The 30 calendar days of service can be broken rather than continuous.
Managerial employees fall outside PD 851. The Labor Code defines them as those vested with powers to lay down and execute management policies, or to effectively hire, transfer, suspend, discipline, or dismiss staff. Job titles do not settle it. A supervisor who only recommends actions without the authority to make them stick is rank-and-file, and stays entitled.
Employers paid on a purely commission, boundary, or task basis are also excluded, though piece-rate workers remain covered. Government employees are outside the decree entirely, since it applies to the private sector.
Prorated 13th Month Pay
New hires, resigned staff, and terminated employees all receive a proportionate amount based on the time they worked during the year. Resigning before December forfeits nothing. Any employer claiming the benefit is lost on resignation is misreading the law, and DOLE treats non-payment as a money claim.
For separated employees the amount forms part of final pay. DOLE Labor Advisory No. 06, Series of 2020 requires final pay to be released within 30 days of the last day of employment unless a more favorable company policy or agreement applies.
| Monthly Basic | Months Worked | 13th Month Pay |
|---|---|---|
| ₱18,000 | 3 | ₱4,500 |
| ₱18,000 | 6 | ₱9,000 |
| ₱18,000 | 12 | ₱18,000 |
| ₱35,000 | 6 | ₱17,500 |
| ₱35,000 | 12 | ₱35,000 |
Is 13th Month Pay Taxable
13th month pay and other benefits are exempt from income tax up to a combined ₱90,000 per calendar year under Section 32(B)(7)(e) of the Tax Code, as amended by the TRAIN Law. Only the excess is taxed. That ceiling has been in place since 2018 and is unchanged for 2026.
The ceiling is shared, which is what catches higher earners out. Christmas bonuses, mid-year bonuses, productivity incentives, and anniversary gifts all draw from the same ₱90,000. An employee with ₱80,000 of 13th month pay and a ₱20,000 Christmas bonus has ₱10,000 of taxable excess, even though neither payment alone crosses the line. That excess stacks on annual compensation and is taxed at the marginal rate.
De minimis benefits sit outside this bucket and carry their own separate ceilings, which BIR Revenue Regulations No. 29-2025 raised for 2026. Keeping small allowances properly classified as de minimis therefore protects more of the ₱90,000 for actual bonuses.
| Annual Taxable Income | Rate on Excess |
|---|---|
| Up to ₱250,000 | 0% |
| ₱250,001 to ₱400,000 | 15% |
| ₱400,001 to ₱800,000 | 20% |
| ₱800,001 to ₱2,000,000 | 25% |
| ₱2,000,001 to ₱8,000,000 | 30% |
| Above ₱8,000,000 | 35% |
When 13th Month Pay Must Be Paid
The deadline is 24 December, with no grace period. Employers may split the benefit, releasing half before the school year opens and the balance in December, provided the full amount clears by the 24th. Paying late puts the company in violation of PD 851 and exposes it to money claims and inspection findings.
A second obligation lands three weeks later. Every covered employer files a compliance report with DOLE by 15 January under Section 8 of PD 851, submitted through the online portal at reports.dole.gov.ph. Size does not exempt anyone, and the requirement applies to all private sector employers.
| Obligation | Deadline |
|---|---|
| Release 13th month pay | 24 December |
| Optional first tranche | Before school year opens |
| DOLE compliance report | 15 January |
| Final pay for separated staff | 30 days from last day |
How 13th Month Pay Affects Other Computations
The benefit does not enter the regular wage. PD 851 keeps it out of the base used for overtime and premium pay, fringe benefits, and contributions to SSS, PhilHealth, and Pag-IBIG, along with private retirement plans. Payroll systems that fold it into the contribution base overstate both employer and employee deductions for December.
13th Month Pay Philippines FAQ
Common questions about computation, eligibility, and tax.
Add up the basic salary you actually earned from January to December, then divide by 12. That is the whole formula under Presidential Decree No. 851. If you earned ₱300,000 in basic salary for the year, your 13th month pay is ₱25,000. The divisor is always 12, even if you worked only part of the year, which is what makes a partial year produce a smaller amount rather than a full month’s salary.
Multiply your monthly basic salary by the months you actually worked, then divide by 12. Someone earning ₱20,000 a month who worked six months earned ₱120,000 in basic salary, so the 13th month pay is ₱10,000. Dividing by six instead of 12 is the most common error, and it overpays: it would produce ₱20,000, a full month’s salary that the employee has not yet accrued.
Only above ₱90,000. Under Section 32(B)(7)(e) of the Tax Code as amended by the TRAIN Law, 13th month pay and other benefits are exempt from income tax up to a combined ₱90,000 per calendar year, and only the excess is taxed. That ceiling is shared, so your Christmas bonus, mid-year bonus, and performance incentives count toward the same ₱90,000. The ceiling took effect in 2018 and has not changed for 2026, though a bill to raise it to ₱150,000 has been filed and remains pending.
Every rank-and-file employee in the private sector who worked at least one month during the calendar year, regardless of how they are paid or what their employment status is. Probationary, project-based, fixed-term, and piece-rate workers are all covered. Managerial employees are excluded under PD 851, meaning those who can lay down management policy or effectively hire, fire, and discipline staff. Supervisors without that authority are usually rank-and-file and stay covered.
On or before 24 December each year. Employers may split it, paying half before the school year opens and the balance by 24 December, but the full amount has to be settled by that date. There is no grace period. Employers separately have to file a compliance report with DOLE by 15 January through the online portal at reports.dole.gov.ph, and that requirement applies to every private employer regardless of size.
Unpaid ones do. The benefit is based on basic salary actually earned, so unpaid absences, unpaid leave, and undertime lower the total you divide by 12. Paid leave has no effect, because the salary was still earned. This is why two employees on identical rates can receive different amounts.
Yes, prorated for the portion of the year they worked. Resignation or termination before December does not forfeit the benefit, and any employer saying otherwise is wrong. The amount forms part of final pay, which DOLE Labor Advisory No. 06, Series of 2020 requires to be released within 30 days of the last day of employment.
No. 13th month pay is mandatory under PD 851 and a Christmas bonus is discretionary. An employer cannot substitute a smaller Christmas bonus for the statutory amount, and if the bonus falls short, the difference is still owed. Both count toward the same ₱90,000 tax-exempt ceiling, so the December payslip should show them as separate lines.
The SSS maternity benefit is excluded, since it comes from SSS rather than the employer and is not basic salary earned. The salary differential your employer pays on top of the SSS benefit is included in basic salary for 13th month purposes, per the DOLE Handbook. Months spent on maternity leave therefore contribute less than fully worked months.
