A mandatory or customary extra month's salary paid to employees in many countries, typically disbursed in December, separate from any performance-based bonus program.
Key Takeaways
13th month pay is an extra month's salary paid to employees once per year, typically in December. In countries where it's mandatory, every eligible employee receives it. No performance review needed. No company profit threshold required. The employee worked for the year, so they get the extra pay. The concept originated in countries where workers' annual earnings were traditionally distributed across 13 payments instead of 12. Over time, labor laws formalized this practice into a statutory right. Today, it's a cornerstone of employment law in Latin America, parts of Europe, and several Asian countries. For global companies, 13th month pay creates a compliance minefield. It interacts differently with local tax codes, social security systems, and employment contracts in every country. Treating it as a "bonus" in your HRIS when it's actually a statutory entitlement is a common mistake that leads to incorrect tax withholding and unhappy employees.
Each country has its own rules for calculation, timing, eligibility, and tax treatment. Here are the major markets.
Presidential Decree No. 851 requires all employers to pay 13th month pay to rank-and-file employees who have worked at least one month during the calendar year. The payment must be made on or before December 24. Calculation: total basic salary earned during the year divided by 12. Overtime, holiday pay, and night differential are excluded from the base. The first PHP 90,000 of 13th month pay is tax-exempt. Amounts exceeding this threshold are taxable income. Employers who fail to pay face fines and potential criminal charges. Some companies pay in two installments: 50% in May or June and 50% in December.
The "13o salario" (13th salary) is required under Federal Law No. 4.090/1962. It's paid in two installments: the first between February 1 and November 30 (at least 50% of the total), and the second by December 20. Calculation: one month's gross salary based on the December rate. If the employee received a raise during the year, the December salary applies, which means the 13th month reflects the highest salary of the year. FGTS (severance fund) contributions and INSS (social security) deductions apply. It's fully taxable. Part-time employees and domestic workers are also entitled.
The "Aguinaldo" must be paid before December 20 each year. The minimum is 15 days of salary for employees with 12 months of service, prorated for those with less. Many employers pay more than the minimum as a competitive practice, with 30, 40, or even 60 days being common in sectors like banking and technology. The first 30 days of minimum daily salary equivalent is tax-exempt. Any amount above that is taxable. Unlike most countries, Mexico's 13th month pay is based on days of salary rather than monthly salary, which changes the calculation for employees with variable schedules.
In Portugal, employees receive both a 13th and 14th month salary, paid in June and November respectively. Spain has a similar structure with two extra payments ("pagas extras"). Italy's "tredicesima" is typically paid in December. Greece mandates a 13th and 14th month salary for private sector employees, though these were reduced during the financial crisis. Austria, Germany, and the Netherlands don't have statutory 13th month requirements, but many collective bargaining agreements include them, making them effectively mandatory for covered industries.
The "Tunjangan Hari Raya" (THR) is a religious holiday allowance equivalent to one month's salary, paid at least 7 days before the employee's major religious holiday (typically Eid al-Fitr for Muslim employees, Christmas for Christians, etc.). Government Regulation No. 36/2021 covers the requirements. Employees with 12+ months of service receive one full month's salary. Those with 1 to 12 months receive a prorated amount. The THR is separate from any contractual bonus and cannot be substituted for one.
The standard formula is simple, but variations across countries create complexity for payroll teams managing global workforces.
Basic formula: Total Basic Salary Earned During the Year / 12 = 13th Month Pay. For an employee earning PHP 30,000 per month in the Philippines who worked the full year: PHP 30,000 x 12 / 12 = PHP 30,000. For an employee who started on July 1: PHP 30,000 x 6 months / 12 = PHP 15,000 (prorated). The tricky part is defining "basic salary." In most countries, it includes only the fixed regular salary. Overtime, commissions, allowances, and variable pay are typically excluded. In Brazil, however, the calculation uses gross salary (including certain allowances), and in some countries, it's based on the most recent month's salary, not the average.
Employees who don't work the full calendar year receive a prorated 13th month. The proration is based on the number of months (sometimes days) actually worked. In the Philippines, an employee who worked from March to December (10 months) receives 10/12 of their monthly basic salary. In Brazil, fractions of 15 days or more within a month count as a full month for proration purposes. Terminated employees are entitled to the prorated amount in most jurisdictions, paid as part of their final settlement.
13th month pay has different tax implications depending on where the employee is located. This creates payroll complexity for multinational employers.
The Philippines exempts the first PHP 90,000 of combined 13th month pay and other benefits from income tax. Mexico exempts the first 30 days of minimum daily salary. In most other countries, 13th month pay is fully taxable as regular income. The exemption thresholds change periodically, so payroll teams must verify the current limits at the start of each fiscal year.
In Brazil, the 13th month salary is subject to INSS (social security) contributions and FGTS (severance fund) deposits. In Italy, the tredicesima is subject to INPS contributions. In the Philippines, 13th month pay is excluded from PhilHealth, SSS, and Pag-IBIG contribution calculations. These variations mean that the employer's total cost of 13th month pay differs significantly by country: in Brazil, the true cost is roughly 130% of the base amount after mandatory contributions.
Non-compliance with 13th month pay laws carries real consequences. Here's what happens when employers get it wrong.
The Department of Labor and Employment (DOLE) actively investigates 13th month pay complaints. Employers who fail to pay can face administrative fines, closure orders for repeat violations, and criminal prosecution. During the holiday season, DOLE sets up hotlines and complaint desks specifically for 13th month pay issues. In 2023, DOLE received over 3,000 complaints related to non-payment or underpayment of 13th month pay.
The Ministry of Labor (now part of the Ministry of Economy) conducts inspections and can impose fines for late or missing payments. Brazilian labor courts are employee-friendly, and 13th salary claims are among the most common in the system. Interest and monetary correction apply to late payments, and repeat violations can trigger doubled penalties.
Using the wrong salary base (including or excluding components incorrectly). Missing the payment deadline by even one day. Failing to prorate for mid-year hires. Attempting to combine 13th month pay with a discretionary bonus into a single payment (this doesn't satisfy the statutory requirement). Not paying 13th month to terminated employees as part of final settlement. Misclassifying 13th month pay in the HRIS, leading to incorrect tax calculations.
For companies with employees in multiple countries, managing 13th month pay requires coordination across payroll, finance, and legal teams.
Global HR teams must understand the distinction, because conflating the two creates legal and financial problems.
| Feature | 13th Month Pay | Annual Bonus |
|---|---|---|
| Legal basis | Statutory requirement in many countries | Employer discretionary or contractual |
| Performance linkage | None. Paid regardless of performance | Typically tied to individual/company performance |
| Amount | Usually one month's basic salary | Variable: 5% to 100%+ of base salary |
| Timing | Mandated deadline (e.g., Dec 24 in Philippines) | Employer determines (usually Q1 of following year) |
| Eligibility | All rank-and-file employees (country-specific) | Defined by employer policy |
| Tax treatment | May have exempt thresholds | Fully taxable as supplemental wages |
| Can employer skip payment? | No (where legally mandated) | Yes, if discretionary and clearly documented |
Accurate budgeting for 13th month pay prevents cash flow surprises and ensures compliance across all operating countries.
