13th Month Salary: A Global Guide

What is the 13th month salary?

When dealing with international payroll, you will undoubtedly encounter terms such as ‘Christmas bonus’, ‘year-end bonus’ and ‘holiday pay’. 
However, the concept of a 13th month payment may be unfamiliar to some; particularly those based in the UK and USA. 

While many private-sector companies may offer discretionary, performance-based bonuses, in certain countries, the reference to a 13th month – and in some cases, a 14th month –  salary represents additional compensation granted to employees. 

This compensation can be mandated by local labour laws or observed as a customary practice by employers. 

The intricacies of the 13th month salary and the expectations surrounding these additional payments vary greatly depending on the country in question. 

Navigating this can be somewhat challenging for employers when hiring internationally. Therefore, it is essential to budget accordingly to ensure all employee entitlements are met and comply with local labour legislation. 

13th month calendar

What are the origins of the 13th month salary?

In the 1970s, the Philippines introduced the concept of the 13th-month pay as a statutory compensation for employees ahead of the festive season.
Under PD 851, the 13th-month pay became mandatory for all employees, setting it apart from the voluntary Christmas bonus. This was typically awarded at the employer’s discretion and often reserved for employees in higher salary brackets or managerial positions.

What are the benefits of the 13th month salary?

Introducing a mandatory, universal bonus successfully closes the gap for those with lower-level salaries, particularly those who are not awarded discretionary bonuses in their job roles.  Undoubtedly, this additional remuneration serves as a powerful tool for improving employee morale, job satisfaction, and retention rates. Furthermore, typically being paid at Christmas or ahead of the holiday season, it provides a much-needed financial incentive during what is typically an expensive time of year.
As a result, this boost in income has proven to increase consumer spending in countries who have adopted the policy, ultimately contributing to economic growth.

How does the 13th month salary vary around the world?

As the concept of the 13th month pay continues to evolve globally, it remains a vital tool for improving employee well-being and financial stability across various cultures and industries. Indeed, many countries have introduced laws mandating the payment to coincide with Christmas, religious festivals, and/ or the summer vacation period. 

The terminology may also vary from country to country, with the term 13th month being adopted for payroll processing due to the nature of the payment being equal to an additional month’s salary. 
Similarly, the term ‘14th month‘ has been coined in countries where14 pay instalments are observed. 

How is the 13th month pay processed?

It is imperative that the payment be processed through payroll and is subject to any applicable deductions. 13th month payments (or equivalent) may be tax exempt in some countries; therefore, it is essential to ensure the remuneration is processed correctly and itemised in payslips. 

In countries where the bonus is regulated by law, the manner and timing of the payment should adhere to local legislation or applicable collective bargaining agreements. The contract of employment should stipulate the terms observed for any additional payment due to employees.

At the end of an employment relationship, employees will typically be entitled to a pro-rated amount of the 13th month (and 14th month) salary, and employers should budget for this accordingly.

How is the 13th month salary calculated?

The computation of the payment varies on a country-specific basis and may be included in the gross annual salary, as is observed in Italy, (total gross salary/14) or in addition to the base salary, akin to the practice in the Philippines and Switzerland, where the 13th-month payment is made as an additional payment equal to 1/12 of the base salary.

Some countries may also see the 13th month payment divided across two instalments, as is the case in Brazil and Greece

It is, therefore, crucial to clearly communicate this arrangement to the employee through contractual documentation, specifying whether the total gross remuneration encompasses or excludes additional payments.

In some countries, employers have greater discretion in determining how and when the payment is made, as long as the employee receives all compensation due over the course of the year. For instance, in Spain and Portugal, employers can choose to divide the salary into either 12 or 14 equal instalments.

For employees who have not worked for the full year, the employer should award a pro-rated amount:

(Base monthly salary x number of months worked within the year) / 12
