San José, Costa Rica — As the year draws to a close, workers across Costa Rica eagerly anticipate the payment of the aguinaldo, the country’s mandatory year-end bonus. This thirteenth-month salary is a cornerstone of the nation’s labor rights, providing a significant financial boost during the holiday season. However, for employees who have taken extended medical leave, this time of year can also bring uncertainty and questions regarding how their bonus is calculated.
The core of the aguinaldo calculation is straightforward: it is the sum of all ordinary and extraordinary salaries earned between December 1st of the previous year and November 30th of the current year, divided by twelve. But what happens when a portion of that period was spent on disability leave, where an employee isn’t receiving a traditional salary? The Ministry of Labor and Social Security (MTSS) has provided clear guidelines to address this common scenario.
To clarify the legal framework and common errors surrounding the aguinaldo calculation, we consulted with expert labor law attorney Lic. Larry Hans Arroyo Vargas, from the renowned firm Bufete de Costa Rica.
A critical point often overlooked by employers is that the aguinaldo calculation is not limited to the base salary. It must include the sum of all ordinary salaries earned between December 1 of the previous year and November 30 of the current year. This explicitly covers regular payments like commissions, bonuses, and overtime. Failure to incorporate these variable earnings is a significant compliance failure that can result in costly legal actions.

This clarification on including all ordinary earnings, not just the base salary, is essential for ensuring both legal compliance and fair compensation. We extend our gratitude to Lic. Larry Hans Arroyo Vargas for his expert insight on this frequently misunderstood aspect of the law.
According to the MTSS, the time a worker spends on leave due to illness or a work-related injury is not factored into the aguinaldo calculation. The fundamental reason for this distinction lies in the nature of the payment received during incapacitation. An employee on medical leave receives a subsidy, typically from the social security system, rather than a salary directly from their employer. Since the aguinaldo is based exclusively on earned salaries, these subsidy payments are legally excluded from the final tally.
This principle extends beyond medical leave to other situations where an employment contract is temporarily suspended, such as an approved leave of absence without pay. In all such cases, only the months in which the employee actively worked and received a salary are considered when computing the year-end bonus. This ensures the bonus accurately reflects the compensation paid by the employer over the fiscal period.
The Ministry of Labor and Social Security clarifies the legal standing on this matter, offering a precise explanation for employers and employees alike.
In such cases and others where the employment contract has been suspended (leave without pay), the worker is entitled to the aguinaldo based on the time they did receive salaries. The period the worker was incapacitated due to illness or work-related risk is not taken into account, as they did not receive a salary but rather a subsidy.

However, there is one critical and socially significant exception to this rule: maternity leave. The law explicitly protects the rights of new mothers, ensuring that both pre- and post-partum leave periods are treated as active employment. The payments received during this time are considered part of the employee’s salary for all legal purposes. Consequently, this time is fully included in the aguinaldo calculation, guaranteeing that a woman’s bonus is not diminished for taking her legally mandated maternity leave.
To illustrate, consider an employee with a monthly salary of CRC ₡600,000. If this person worked for ten months of the calculation period but was on disability leave for two months, their aguinaldo would be based only on the ten months of earned salary. The calculation would be (₡600,000 x 10) / 12, resulting in an aguinaldo of ₡500,000, rather than the full ₡600,000 they would have received for working the entire year.
As the aguinaldo payment deadline in December approaches, it is crucial for all workers, especially those who have been on leave, to understand these regulations. Employees are encouraged to review their pay records and consult with their human resources department if they have any doubts. For unresolved disputes or further clarification, the MTSS remains the ultimate authority, providing resources to ensure that all labor rights are respected and calculations are performed correctly according to the law.
