13th month pay is a legally mandated extra payment every rank-and-file employee in the Philippines must receive: one twelfth of the basic salary they earned within the calendar year, paid on or before December 24. It is not a bonus and not discretionary — it is law.
The legal basis
13th month pay was established by Presidential Decree No. 851 in 1975 and remains in force, administered by the Department of Labor and Employment (DOLE). It covers all rank-and-file employees who have worked at least one month during the calendar year, regardless of how they are paid or the nature of their employment.
Foreign employers hiring in the Philippines — directly, through a BPO, or through an employer of record — routinely miss this in their first cost model. It is not optional, and DOLE requires employers to report compliance each January.
The exact calculation
The formula is: total basic salary earned during the calendar year ÷ 12. "Basic salary" excludes allowances, overtime, holiday premium, night differential, and monetary benefits not integrated into the base wage.
An employee who worked the full year at an unchanged monthly salary receives one full month's basic pay. An employee who joined mid-year receives a proportional amount: if they earned six months of basic salary, they receive six twelfths — half a month's pay. Resigned or terminated employees are entitled to the proportional amount for the months they worked.
Deadline and payment practice
The law requires payment on or before December 24. Many employers pay half in May or June and the balance in December; that is compliant as long as the full amount lands by the deadline.
In the BPO industry, 13th month pay is universal by definition — every agent, team leader, and support employee on Philippine payroll receives it. Cost models that quote a monthly salary without a thirteenth month understate annual cost by roughly 8.3%.
Tax treatment
13th month pay and other benefits are income-tax-exempt up to a ceiling set by the tax code — ₱90,000 since the TRAIN Law took effect in 2018. Amounts above the ceiling are taxable. For typical BPO salaries the full 13th month payment falls under the ceiling and arrives untaxed.
13th month vs. 14th month pay
Only the 13th month is required by law. A 14th month payment — which some employers grant mid-year or at Christmas — is purely discretionary and contractual. Job candidates comparing offers should read "guaranteed 14th month" as a real differentiator and "13th month pay" as the legal minimum every employer must provide anyway.
Common questions
01Who is entitled to 13th month pay?
All rank-and-file employees in the private sector who worked at least one month in the calendar year — regardless of position title, employment status, or how wages are paid. Managerial employees, as defined by the Labor Code, are the main exclusion, though many employers extend it to them voluntarily.
02Is 13th month pay the same as a Christmas bonus?
No. 13th month pay is a statutory obligation under PD 851 with a fixed formula and deadline. A Christmas bonus is discretionary. An employer can pay both, but only one is required by law.
03Do employees who resign before December still get it?
Yes — proportionally. An employee who resigns after seven months receives seven twelfths of a month's basic salary, typically released with their final pay.
