Frequently Asked Questions
Who is entitled to 13th month pay in the Philippines?
All rank-and-file employees in the private sector who have worked at least one (1) month during the calendar year, regardless of position, employment status, or how their wages are paid.
When is 13th month pay released?
Employers must pay it on or before December 24 each year. Some companies split it into two — half in May/June and the rest in December.
How is 13th month pay computed?
Total basic salary earned during the calendar year ÷ 12. 'Basic salary' excludes allowances, overtime, holiday pay, night differential, and unused leave conversions.
How much is the 13th month pay of a ₱30,000 monthly salary?
If you worked the full year at ₱30,000 basic monthly salary with no unpaid leave, your 13th month pay is ₱30,000 (₱360,000 total basic ÷ 12) and it is fully tax-free because it is below the ₱90,000 cap.
How do I compute a prorated 13th month pay?
Multiply your monthly basic salary by the number of months you actually worked, subtract any unpaid leave, then divide by 12. Example: ₱25,000 × 7 months ÷ 12 = ₱14,583.33.
Is 13th month pay taxable?
Yes, but only the portion exceeding ₱90,000 when combined with other bonuses (e.g. 14th month, Christmas bonus, productivity incentives) is subject to income tax.
What if I resigned before December?
You're still entitled to a prorated 13th month pay based on the number of months you actually worked that year, paid as part of your final pay.
Do unpaid leaves reduce my 13th month pay?
Yes. Days without pay (LWOP) are not part of basic salary earned, so they lower the total that gets divided by 12. This calculator estimates the deduction using a 22-working-day month.
Is 13th month pay the same as a Christmas bonus?
No. 13th month pay is mandatory under PD 851. A Christmas bonus is voluntary and given at the employer's discretion, though both count toward the ₱90,000 tax-exempt cap for benefits.
Are SSS, PhilHealth and Pag-IBIG deducted from 13th month pay?
No. Mandatory contributions are computed on your monthly basic salary, not on your 13th month pay. Only income tax can be withheld, and only on the portion above ₱90,000.
Do government employees get 13th month pay?
Government workers receive a year-end bonus and cash gift under separate laws instead of PD 851. This calculator follows the private-sector PD 851 rules.
Are kasambahay and probationary employees covered?
Yes. Kasambahay (domestic workers) are entitled to 13th month pay under RA 10361, and probationary, contractual, and project-based rank-and-file employees are covered once they have worked at least one month in the year.
