How to Compute Your 13th Month Pay (Philippines, 2026)
Your 13th month pay is one-twelfth of the total basic salary you earned this year — a legal right for rank-and-file employees, payable by December 24. Here's the exact formula, the tax rule, and a worked example.
Educational only — not legal or tax advice. Based on PD 851 (DOLE) and the TRAIN law (BIR). Confirm specifics with your HR or a licensed professional.
The formula
13th month pay = total basic salary earned this year ÷ 12. “Basic salary” is your base pay only — it excludes overtime, holiday and night-differential pay, allowances, and cash conversions of unused leave.
- Full year worked. ₱25,000/month × 12 months ÷ 12 = ₱25,000 — one month of basic pay.
- Joined mid-year (pro-rated). ₱25,000/month × 7 months ÷ 12 = ₱14,583.
Who gets it, and when
Every rank-and-file private-sector employee who worked at least one month in the calendar year is entitled, no matter their position or pay scheme. It must be paid on or before December 24(some employers split it — half mid-year, half in December).
Is it taxed?
Your 13th month pay plus other benefits (Christmas bonus, etc.) are tax-free up to ₱90,000combined, per year, under the TRAIN law. Only the portion above ₱90,000 is added to your taxable income. For most Filipinos, the entire 13th month is tax-free.

Make it count
A 13th month spent by January is a missed chance. The highest-leverage moves: top up your emergency fund, clear any high-interest debt, or invest a chunk — even ₱10,000 invested and left to compound matters more than the amount suggests.
Frequently asked questions
How is 13th month pay computed?
Add up your total BASIC salary earned during the calendar year and divide by 12. Basic salary excludes overtime, holiday pay, night differential, allowances, and cash conversions of unused leave. So someone earning ₱25,000/month who worked the full year gets ₱25,000 — one month of basic pay.
Who is entitled to 13th month pay?
All rank-and-file employees in the private sector who have worked at least one month during the calendar year, regardless of position or how they are paid, are entitled by law (PD 851). Managerial employees are not legally covered, though many employers still grant it.
When should it be paid?
Not later than December 24 each year. Some employers split it — half mid-year, half in December.
Is 13th month pay taxed?
Your 13th month pay plus other benefits (like a Christmas bonus) are tax-FREE up to ₱90,000 total per year under the TRAIN law. Only the amount ABOVE ₱90,000 is added to your taxable income.
What if I resigned or was hired mid-year?
You still get a PRO-RATED 13th month based on the months you actually worked. Example: ₱25,000/month for 7 months = ₱25,000 × 7 ÷ 12 ≈ ₱14,583.
