What Is a 13th Month Pay and How Does It Work?
It’s Not a Bonus. It’s the Law.
If you’re hiring in the Philippines for the first time, one term will come up in almost every conversation about compensation: 13th month pay. Many Australian employers assume it’s a discretionary bonus — something offered by generous companies to keep staff happy. It’s not. 13th month pay is a statutory entitlement, mandated by Philippine law, and failing to pay it on time carries real legal consequences.
Here’s everything you need to know — including how to calculate it, when to pay it, and how to account for it in your hiring budget.
1. What Is 13th Month Pay?
13th month pay is a mandatory cash payment equivalent to one month’s basic salary, required under Presidential Decree No. 851, signed into law in 1975. It applies to all rank-and-file employees in the private sector — regardless of their employment status (regular, contractual, or project-based), as long as they have worked for at least one month in the calendar year.
The payment must be made on or before December 24 of each year.
13th month pay is tax-exempt up to PHP 90,000 (approximately AUD 2,370) under current Philippine tax law. Amounts above this threshold are subject to withholding tax — though in practice, most rank-and-file employees fall below the exempt threshold.
2. Who Is Entitled?
The entitlement covers all rank-and-file employees who have worked for at least one month during the calendar year. This includes:
- Full-time employees
- Part-time employees (pro-rated)
- Project-based employees (for the duration of the project)
- Employees on probation
- Employees who have resigned or been terminated before December (pro-rated to their last day)
Managerial employees are technically excluded from the statutory requirement — but many Philippine employers extend the benefit to managers as a standard practice. When in doubt, consult your EOR provider on local norms for the role.
3. How to Calculate It
The formula is straightforward:
13th Month Pay = Total Basic Salary Earned in the Calendar Year ÷ 12
“Basic salary” means the fixed base pay — it does not include allowances, overtime pay, holiday pay, night differential, or other supplementary compensation.
| Scenario | Monthly Basic Salary | Months Worked | 13th Month Pay Due |
|---|---|---|---|
| Full year employee | AUD 2,100 | 12 | AUD 2,100 |
| Mid-year hire (started July) | AUD 2,100 | 6 | AUD 1,050 |
| Part-time (half days) | AUD 1,050 (effective) | 12 | AUD 1,050 |
| Resigned in September | AUD 2,100 | 9 | AUD 1,575 |
Employees who resign or are terminated before December are still entitled to their pro-rated 13th month pay, which should be released with their final pay.
4. When Must It Be Paid?
The legal deadline is on or before December 24 each year. Most employers process payment in the first two weeks of December to allow for payroll processing time.
Some companies split the payment: half in June (often called a “mid-year bonus” or “6th month pay”) and the remaining half in December. While this isn’t required by law, it’s a common practice that employees appreciate — and it can help with cash flow planning on the employer side.
Late payment is a violation of Philippine labour law and can result in complaints filed with the Department of Labor and Employment (DOLE).
5. Common Mistakes Foreign Employers Make
Australian businesses new to hiring in the Philippines make the same mistakes repeatedly. Here are the most common ones:
Treating it as optional. 13th month pay is not a bonus you can withhold if performance is below expectations. It is a statutory right, regardless of performance.
Confusing it with a Christmas bonus. A Christmas bonus (sometimes called a 14th month pay) is discretionary. 13th month pay is not. They are separate things.
Forgetting to budget for it annually. Many businesses budget based on monthly salary and are caught off guard by the December liability. Add 8.33% to your annual salary budget (1 ÷ 12 = 8.33%) to account for 13th month pay from day one.
Not pro-rating for mid-year hires. A hire who starts in September is still entitled to 13th month pay for the months they worked — don’t overlook this in their first-year compensation.
Including allowances in the base salary calculation. Transportation allowances, meal subsidies, and other benefits are not “basic salary” and should not be included in the 13th month pay calculation.
6. How EOR Handles This For You
One of the practical advantages of using an Employer of Record is that 13th month pay is handled automatically — no surprises, no risk of missing the deadline.
Your EOR provider tracks each employee’s tenure and basic salary throughout the year, calculates the exact 13th month pay liability for each employee, and ensures payment is processed on time in December. The cost is reflected in your monthly invoice — typically amortised as a 1/12 loading each month — so there’s no unexpected AUD 2,000+ hit in December.
For businesses managing payroll directly without an EOR, building this accrual into your monthly bookkeeping is essential.
Want Compliance Handled For You?
13th month pay is one of a dozen compliance obligations that come with hiring in the Philippines. SSS, PhilHealth, Pag-IBIG, BIR tax filings, employment contracts, and termination procedures all have specific rules — and the consequences of getting them wrong range from employee complaints to regulatory action.
Our local EOR team manages all of it. You focus on the work; we handle the compliance.
