13th Month Pay: 1/12 of Basic, Due 24 December

The formula

13th month pay is one-twelfth (1/12) of the total basic salary you earned during the calendar year. That is a floor, not a ceiling: the advisory says the minimum shall not be less than 1/12, and anything better in your contract, company practice or collective bargaining agreement still stands.

The divisor is always 12. It does not change to match the months you worked, which is the single most misunderstood part of the rule. Work seven months and you divide seven months of basic salary by twelve.

DOLE’s own worked examples

The advisory works three cases. These are DOLE’s figures, not illustrations of mine.

A regular employee with some unpaid leave:

₱209,774.20 divided by 12 gives ₱17,481.18.

Notice what unpaid leave does. It does not disqualify anyone; it lowers the basic salary actually earned, and the 13th month pay falls with it. Paid leave, in June, changes nothing.

A piece-rate worker. Piece-rate means payment based on production, the amount or quantity of work done rather than time employed. The basis is total earnings from production during the year, divided by 12. DOLE’s example: ₱120,000.00 of output across January to December gives ₱10,000.00.

Fixed wage plus commission. Here the commission drops out:

₱216,782.12 divided by 12 gives ₱18,065.18. The ₱30,000.00 of commission is excluded entirely.

What counts as basic salary

Basic salary means all remuneration or earnings paid by your employer for services rendered. The advisory then lists what it does not include:

• The cash equivalent of unused vacation and sick leave credits
• Overtime pay
• Premium pay
• Night shift differential
• Holiday pay
• Cost of living allowance

There is one important exception. If any of these are already treated as part of your basic salary through an individual or collective agreement, company practice or policy, then they are included. So the answer for two people at the same company can genuinely differ depending on what their contracts say.

Commissions are excluded by case law rather than by the list. DOLE cites Boie-Takeda Chemicals, Inc. vs. De la Serna, G.R. No. 92174 and G.R. No. 102552, decided 10 December 1993, where the Supreme Court held that commissions, while part of the generic term wage, are not part of basic salary for this purpose.

Who is covered

The coverage is deliberately wide. The advisory grants it to rank-and-file employees in the private sector regardless of position, designation, or employment status, and irrespective of the method by which their wages are paid, provided they worked at least one (1) month during the calendar year.

It then names groups that are often assumed to be excluded and are not:

The maternity case is worth spelling out. The benefit itself is paid by SSS rather than by your employer, and what your employer owes on top is the salary differential. How that benefit is computed is in the SSS maternity benefit guide.

The one month of work is the only threshold. There is no minimum length of service beyond it and no exclusion for probationary or fixed-term staff.

No exemption, no deferment

The advisory closes one door explicitly:

No request or application for exemption from payment of 13th month pay, or for deferment of its payment shall be accepted and allowed.

There is no form for this because there is no process. An employer in difficulty does not have a route to defer it.

The compliance report employers owe

This part is aimed at employers but is worth knowing as an employee, because it means DOLE holds a record.

Employers must report compliance through the DOLE Online Compliance Portal at reports.dole.gov.ph. The report covers eight items:

1. Name of establishment
2. Address
3. Principal product or business
4. Total employment
5. Total number of workers benefitted
6. Amount granted per employee
7. Total amount of benefits granted
8. Name, position and telephone number of the person giving the information

Compliance is monitored by the DOLE Regional, Field or Provincial Office with jurisdiction over the workplace, under Department Order No. 238, Series of 2023.

How it is taxed

13th month pay is not tax-free without limit. It sits inside the annual exclusion for 13th month pay and other benefits, and anything above that threshold is taxable compensation. What your employer reports, and the certificate you receive each January, is covered in BIR Form 2316. The rate that applies to any taxable excess is in the BIR income tax table.

A note on dates

The rules above come from Labor Advisory No. 16, Series of 2025, signed 15 November 2025, which is the most recent guidance DOLE has published. DOLE reissues this advisory annually and the deadline dates move with the year.

The formula, coverage and exclusions have been stable, because they come from Presidential Decree No. 851 and Article 5 of the Labor Code rather than from the advisory itself. The dates are the part to re-check each December.

Where this goes wrong

Dividing by the months you worked. The divisor is 12, always.

Expecting overtime and night differential to count. They are excluded unless your contract or company practice folds them into basic salary.

Assuming commissions count. They do not, and the Supreme Court settled that in 1993.

Thinking resignation forfeits it. It does not. The proportionate amount is due.

Waiting for an employer’s exemption to come through. No exemption or deferment is accepted or allowed.
