What is 13th Month Pay?
13th month pay is an additional salary payment usually equivalent to one month’s basic pay that employers must provide to employees, either as a legal requirement or as a customary practice in certain countries.
It originated in the Philippines in 1975, when the law mandated employers to provide this benefit. Since then, many countries in Latin America, Asia, and parts of Europe have adopted the practice.
Key Point: Unlike bonuses, which are discretionary and performance-based, 13th month pay is a statutory entitlement in many regions.
AI Payroll Software Connection: Modern payroll systems automatically calculate 13th month pay based on employee salaries, tenure, and local laws removing the risk of manual errors.
Which Countries Require 13th Month Pay?
Employers with global teams must carefully track where 13th month pay is mandatory and where it is optional but customary.
Mandatory Countries (Statutory):
- Philippines – Required by law, paid by December 24.
- Brazil – Known as “Christmas bonus,” paid in two installments.
- Indonesia – Called Tunjangan Hari Raya (THR), paid before religious holidays.
- Mexico – Known as Aguinaldo, must be paid before December 20.
- Guatemala, Ecuador, and other Latin American nations – Similar laws in place.
Customary but Not Mandatory:
- Certain European countries (e.g., Spain, Italy, Portugal) where employers often pay 13th month salaries as part of collective agreements.
For global employers, cloud-based HR systems and payroll outsourcing solutions ensure compliance across jurisdictions without manual tracking.

How is 13th Month Pay Calculated?
The general formula is:
13th Month Pay = (Annual Basic Salary ÷ 12)
Pro-Rated 13th Month Pay for New Employees
Employees who haven’t completed a full year of service still qualify for pro-rated 13th month pay. For example:
- Employee salary = $1,200/month
- Months worked = 6
- 13th month pay = (1,200 × 6) ÷ 12 = $600
Deductions and Taxation
- In some countries, 13th month pay is tax-free up to a limit (e.g., the Philippines).
- In others (like Brazil), it is subject to tax and social security contributions.
