13th month pay computation 2026 Philippines

13th month pay in the Philippines is one-twelfth of the total basic salary an employee actually earned from January 1 to December 31. Every rank-and-file private-sector employee who worked at least one month in the year is entitled to it, and it must be paid by December 24 under Presidential Decree No. 851.

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

13th Month Pay Calculator (2026)

Enter basic salary only. Leave out overtime, allowances, night differential, holiday pay, and COLA unless your company treats them as part of basic salary.

Total basic salary earned₱240,000.00
13th month pay (÷ 12)₱20,000.00

Within the ₱90,000 tax-exempt ceiling, which is shared with other bonuses and benefits paid in the year.

What Counts as Basic Salary

Basic salary means all remuneration paid for services rendered, minus benefits that are not part of the regular or basic salary. Under the DOLE Revised Guidelines on 13th month pay, leave these out:

  • Overtime pay and premium pay for rest days and special days
  • Night differential
  • Holiday pay
  • Cost-of-living allowance (COLA) and other allowances not integrated into basic pay
  • The cash equivalent of unused vacation and sick leave
  • Profit-sharing payments and de minimis benefits

The exception: if an employment contract, collective agreement, or established company practice treats any of these as part of basic salary, include them. Unpaid absences reduce the total, because 13th month pay is based on salary actually earned. See our de minimis benefits guide for which benefits stay outside the computation.

Worked Examples

Full year, same salary

₱20,000 monthly basic salary, January to December, no unpaid absences: ₱240,000 ÷ 12 = ₱20,000.

Unpaid absences

Same ₱20,000 salary, but 10 unpaid leave days at a ₱909 daily rate (₱9,091 deducted): (₱240,000 − ₱9,091) ÷ 12 = ₱19,242.

New hire in April

Started April 1 at ₱25,000 a month: 9 months × ₱25,000 = ₱225,000 ÷ 12 = ₱18,750.

Resigned in August

Last day August 31 at ₱30,000 a month: 8 months × ₱30,000 = ₱240,000 ÷ 12 = ₱20,000, paid with final pay rather than in December.

Daily-paid worker with a mid-year wage increase (Metro Manila)

An NCR non-agriculture minimum wage earner working 26 days a month, paid ₱695/day until September 25, 2026 and ₱755/day from September 26 under Wage Order NCR-28:

  • January to August: 8 × 26 days × ₱695 = ₱144,560
  • September: 22 days × ₱695 + 4 days × ₱755 = ₱18,310
  • October to December: 3 × 26 days × ₱755 = ₱58,890

Total basic salary ₱221,760 ÷ 12 = ₱18,480. Use actual days worked in real payroll; this example assumes a fixed 26 days for clarity. The NCR minimum wage guide explains the NCR-28 change, and the regional wage guide lists 2026 increases in other regions.

Who Is Entitled, and Who Is Not

PD 851 covers all rank-and-file employees of private-sector employers who worked at least one month in the calendar year, regardless of position, designation, employment status, or method of wage payment. That includes probationary, contractual, project-based, and seasonal staff, and workers paid by piece rate or on a fixed wage plus commission. Kasambahay are entitled under RA 10361.

Not covered: managerial employees, government employees, employers already paying a 13th month pay or its equivalent, and employees paid purely on commission, boundary, or task basis.

Common 13th Month Pay Computation Mistakes

Mistake 1: Including non-basic pay. Overtime, COLA, night differential, holiday pay, and leave conversions are not basic salary unless company policy or an agreement makes them so. Including them overstates the amount; leaving out items your policy treats as basic understates it.

Mistake 2: Skipping proration for new hires and separated employees. An employee who worked three months is owed 3/12 of the basic salary earned, and a separated employee's share belongs in final pay regardless of why they left.

Mistake 3: Applying one rate to the whole year. Raises and wage order increases change the monthly basic salary. Use each month's actual rate. In 2026 this affects every region that raised its minimum wage mid-year.

Mistake 4: Forgetting the DOLE compliance report. After paying, employers submit a 13th Month Pay Compliance Report at reports.dole.gov.ph by January 15 of the following year. Missing it is a separate gap from the payment itself.

Is 13th Month Pay Taxable?

Up to ₱90,000 a year of 13th month pay and other benefits is tax-exempt under the TRAIN Law. The ₱90,000 is one shared pool: a mid-year bonus, productivity bonus, or de minimis benefits above their own ceilings all count toward it.

An employee receives ₱40,000 in 13th month pay and a ₱60,000 year-end bonus. Combined, ₱100,000: the first ₱90,000 is exempt and ₱10,000 is added to taxable compensation.

2026 Deadlines

  • December 24, 2026: full 13th month pay released to current employees. If you pay in two halves, the first half goes out before the opening of the school year.
  • Within 30 days of separation: prorated 13th month pay for resigned or separated employees, as part of final pay (DOLE Labor Advisory No. 06-20). See our final pay guide.
  • January 15, 2027: 13th Month Pay Compliance Report due at reports.dole.gov.ph, following the pattern of January 15, 2026 for 2025 payments.

Cash Flow: What the Numbers Look Like

For 30 rank-and-file employees averaging ₱20,000 in monthly basic salary, the 13th month obligation is ₱600,000, all due by December 24. For 50 employees it is ₱1,000,000. The liability builds every payroll cycle from January 1 whether or not anyone is tracking it, which is why employers who accrue it monthly are not scrambling in November.

Frequently Asked Questions

How do you compute 13th month pay in the Philippines?

Add up the total basic salary the employee actually earned from January 1 to December 31, then divide by 12. For an employee on the same ₱20,000 monthly basic salary all year with no unpaid absences, 13th month pay is ₱240,000 ÷ 12 = ₱20,000. Overtime, allowances, night differential, holiday pay, and COLA are left out unless the employer treats them as part of basic salary.

When is the deadline for 13th month pay?

13th month pay must be paid no later than December 24. Employers may pay half before the opening of the regular school year and the other half on or before December 24, as long as the full amount is paid by the deadline.

Who is entitled to 13th month pay?

All rank-and-file employees in the private sector who worked at least one month during the calendar year, regardless of position, employment status (regular, probationary, contractual, project-based), or how their wages are paid. Kasambahay are entitled under the Batas Kasambahay (RA 10361). Managerial employees are not covered by the law, though many employers extend it as policy.

Is 13th month pay taxable?

Up to ₱90,000 a year is tax-exempt under the TRAIN Law (NIRC Section 32(B)(7)(e), RR No. 11-2018). The ₱90,000 is shared with other bonuses and benefits such as a mid-year or productivity bonus. Only the combined amount above ₱90,000 is taxable.

Does 13th month pay include overtime, allowances, or holiday pay?

No. Under the Revised Guidelines on 13th month pay, basic salary excludes allowances not integrated into basic pay, the cash equivalent of unused vacation and sick leave, overtime, premium pay, night differential, holiday pay, and COLA. They are included only if an individual or collective agreement, company practice, or policy treats them as part of basic salary.

What happens to 13th month pay when an employee resigns?

An employee who resigns or is separated for any reason, including dismissal for just cause, is entitled to a proportionate 13th month pay for the basic salary earned that year. It is part of final pay, which DOLE Labor Advisory No. 06-20 says should be released within 30 days of separation.

Does a mid-year salary increase change 13th month pay?

Yes. 13th month pay is based on the basic salary actually earned each month, so the old rate applies to the months before the increase and the new rate after. For example, Metro Manila minimum wage earners were paid ₱695 per day until September 25, 2026 and ₱755 from September 26 under Wage Order NCR-28, so their 2026 13th month pay uses both rates.

Do employers need to file a 13th month pay report with DOLE?

Yes. Covered employers submit a 13th Month Pay Compliance Report through reports.dole.gov.ph by January 15 of the following year. The deadline for 2025 payments was January 15, 2026.
