The short answer: your 13th month pay is your total basic salary earned from January to December, divided by 12. Not your monthly salary — your total basic salary actually earned. The divisor is always 12, even if you only worked part of the year.
If your basic salary is PHP 30,000 a month and you worked the full year, you earned PHP 360,000 in basic salary. Divided by 12, your 13th month pay is PHP 30,000.
If you started in July and earned PHP 180,000 in basic salary by December, your 13th month pay is PHP 15,000 — not PHP 30,000. The divisor does not shrink with the months you worked. This is the single most common thing people get wrong.
Who is entitled to it
Every rank-and-file employee in the private sector who has worked at least one month during the calendar year. That includes probationary, contractual, project-based, part-time and seasonal employees.
Managerial employees are not covered by the law. Many companies grant it anyway as a matter of policy — check your handbook rather than assuming.
When it has to be paid
On or before 24 December. Your employer may split it into two instalments, with the first released by 31 May, but the full amount has to be settled by Christmas Eve.
What does not count toward the computation
This is where the number often comes out lower than people expect. Excluded from basic salary: overtime pay, night shift differential, holiday and rest day premiums, transport, meal and housing allowances, performance bonuses and cash gifts, and the cash conversion of unused leave.
Unless your company or CBA has consistently treated any of these as part of basic salary — in which case past practice matters.
Is it taxed?
Your 13th month pay is tax-exempt up to PHP 90,000, and that ceiling is shared with your other benefits — Christmas bonus, productivity incentives, and similar — in the same calendar year. Anything above PHP 90,000 combined is taxable.
If you resigned or were separated during the year
You are still entitled to a pro-rated amount, computed the same way: total basic salary earned, divided by 12. It should form part of your final pay, which is generally released within 30 days of separation.
This matters more than people realise when they are timing an exit. Leaving in October does not forfeit your 13th month — it reduces it proportionally, and it still has to be paid.
Now the part nobody writes about
I spent years on the HR side of this, and here is what I noticed every December: the money lands, and the mood changes overnight. People who were certain in October that they needed to leave become unsure by the second week of December.
That is not weakness. It is what relief does. But it is worth knowing it is happening to you, because February always comes, and the question you were sure about in October will still be there — just older.
