13th Month Pay: What It Is and How to Calculate It

A guide to thirteenth month salaries for businesses expanding or employing overseas

Published on

As your business expands, or your workforce grows internationally, HR and payroll processes become increasingly complicated.

Complying with international labour law, as well as with cultural expectations, is key to maintaining your company’s reputation, improving employee retention, and avoiding hefty legal fees and financial penalties.

13th month pay is one such concept of which you must be aware in order to stay globally compliant. In this article, we’ll explain what a thirteenth and fourteenth salary is, where 13th month pay is mandatory or customary, and how to calculate it.

To make the global payroll process smoother and be sure of your enterprise’s compliance with all local and international employment laws, including 13th salary, consider working with a trusted global business solutions provider like Mauve.

What is 13th month pay?

The Philippines was the first country to enshrine a 13th month pay package in law, back in 1975, as a sort of mandatory Christmas bonus. 13th month salaries are additional compensation which companies pay their employees once a year, either according to government mandate or national custom. Each 13th month pay is calculated per employee, typically equating to a full month’s pay if the worker is paid monthly, or 1/12 of an individual’s yearly salary.

13th and 14th (and in some countries 15th!) month pay is usually tax-free, and whilst it may often fall on or around Christmas, it is distinct from a Christmas bonus which is often added on top. 13th month pay is particularly prevalent in Latin America, though is becoming moreso elsewhere in the world, including in Asia, Africa and Europe.

A 13th month salary may be included as part of a worker’s legal rights – akin to the legal minimum wage in different countries – in which case you would have to comply with the law or face potentially severe consequences. Alternatively, thirteenth salaries may be culturally, not legally, enforced, in which case failure to provide them may damage your reputation and employee retention.

13th month pay computation – the calculation of how much each individual overseas employee is due – depends also on the laws and customs of the country in question. A little later in this article, we’ll explain how the most common forms of 13th month pay computation work.

Is it mandatory to pay employees a 13th month wage?

Only in countries where 13th month pay is enshrined in law is it mandatory to provide your employees with this additional compensation. However, if you were to neglect paying your overseas employees a 13th month salary in countries where it is customary to do so, you risk losing those employees and damaging your organisation’s reputation.

In which countries is 13th month pay the status quo?

Today, 13th month pay is either compulsory or expected in nearly 50 countries around the globe. Below is a complete list of countries which enforce a 13th month pay model, either legally or culturally.

Is 13th month pay taxable?

Typically, 13th, 14th, and 15th month pay is not taxable. However, should the calculated amount of a 13th month salary exceed the average monthly wage of an employee, it may be taxed as normal pay.

Are all employees eligible for 13th month pay?

In countries where 13th salaries are normal, it is usually the case that all employees are eligible to receive them. However, this is not always the case. In some countries, employees must work for a company for a minimum amount of time (e.g. one month) before becoming eligible, whilst in others certain types of employees – managers, public sector workers, personal service employees and freelancers – are exempt. Typically, those exempted from 13th month pay are workers who are already likely to receive the equivalent of one full month’s salary as an annual bonus.

How to calculate 13th month salaries for your employees

When you plan an overseas expansion – be it opening new offices, or hiring a remote team of salespeople to bring your brand to a new market – one of the more difficult processes to get right is undoubtedly global payroll. The same can be true with regards to international employee relocation. One of the key elements to successfully complying with overseas 13th month pay laws and customs is knowing how to accurately calculate them.

13th month pay computation should be conducted on a country-by-country basis, since different countries (and different collective bargaining agreements within them) will calculate thirteenth salaries in different ways. As a business expanding overseas or hiring workers abroad, it’s crucial you familiarise yourself with the specific calculations used by each of the countries you have a presence in.

The most common way to calculate 13th month pay, as exemplified by the Philippines, is simply to divide the gross annual salary of each employee by 12. The resulting number is the average monthly pay, and thus the amount to pay as a thirteenth salary.

In other countries, like India for example, 13th month pay is calculated as a percentage of annual salary. Whilst in countries like Brazil and Italy, 13th month pay is already included in the contracted salary of each employee (where the practice applies), and thus to calculate it you need to divide your employees’ gross annual salaries by 13.

Other unique 13th month pay computations include Argentina’s famous Aguinaldo system, through which employees receive two equal payments equivalent to 50% of the highest monthly salary they’ve received that year.


13th month pay, also referred to as thirteenth salary, is an increasingly common practice in the world of business. To ensure global compliance and maintain your company’s good reputation, it’s important to be aware of 13th month pay practices and laws within the countries you operate (or intend to operate) in.
