Aguinaldo

The aguinaldo is the Spanish-speaking Latin America name for a statutory year-end bonus that employers must pay their workers in addition to regular salary. It exists across Mexico, Argentina, Bolivia, Costa Rica, Ecuador, Guatemala, Honduras, Nicaragua, Paraguay, Peru, Uruguay, and several other jurisdictions, with each country setting its own calculation formula, payment timing, and statutory threshold. The aguinaldo is the local-language equivalent of the broader 13th month salary concept, although the specific rules vary materially between countries. This guide covers what the aguinaldo is, the country-by-country rules across the major Latin American economies, the worked example of a Mexican aguinaldo calculation, common employer mistakes, tax treatment, and how it differs from the Brazilian 13º salário (décimo terceiro).

In Mexico, the aguinaldo is governed by Article 87 of the Federal Labor Law (Ley Federal del Trabajo, or LFT), which requires every employer to pay at least 15 days of the worker’s daily salary by 20 December each year. Workers who have not completed a full year of service are entitled to a proportional aguinaldo based on the days actually worked during the calendar year. The 15-day baseline is a statutory minimum, and many Mexican employers pay more (typically 20 to 30 days) under collective bargaining agreements, internal policies, or as a competitive talent measure.

For international employers hiring across Latin America, the aguinaldo is one of the most operationally significant compliance points. It is universal across the region, has fixed statutory deadlines that fall in the same period (mid-November to late December for most countries), and triggers labour-inspection scrutiny when missed or under-paid. Foreign employers running global payroll often miscalculate the aguinaldo because they apply the home-country 13th-month calculation methodology rather than the specific country formula, with the result that workers receive less than the statutory minimum and the employer faces back-payment claims and penalties.

The word “aguinaldo” comes from the Spanish term for a gift or bonus traditionally given at the Christmas or New Year season. The concept of a statutory aguinaldo (as a binding labour-law obligation rather than a discretionary gift) emerged across Latin America during the mid-20th century, with Mexico adopting Article 87 LFT in its current form in 1970 and most other regional jurisdictions following with similar provisions through the 1970s and 1980s.

Although the cultural framing varies (some countries explicitly link the aguinaldo to Christmas tradition, others treat it as a year-end compensation mechanism), the operational function is consistent across the region: a statutory year-end payment, calculated as a multiple of daily or monthly salary, payable in December, subject to specific tax treatment, and enforceable through labour inspection. The aguinaldo is not a discretionary bonus and cannot be waived by employee consent or absorbed into regular salary.

The aguinaldo functionally parallels the 13th month salary concept used in many other regions (the Philippines, Indonesia, parts of Europe), but the term “aguinaldo” specifically refers to the Spanish-speaking Latin American implementation. The Brazilian equivalent is called the 13º salário or décimo terceiro and operates under different rules (specifically the two-installment payment structure under CLT). The Portuguese-speaking Brazilian framework is covered separately.

Each Latin American country has its own aguinaldo formula, statutory deadline, and threshold. The table below summarises the major regional jurisdictions as of May 2026. Specific calculation details and statutory references follow in the country sections.

Two patterns are worth noting. First, Mexico is an outlier with the 15-day statutory minimum compared to most regional jurisdictions that mandate a full month’s salary. Second, several countries (Argentina, Uruguay, Peru) split the payment across two annual instalments, while most others pay a single year-end lump sum. Both patterns affect cash flow planning for foreign employers.

Mexico’s aguinaldo is the most widely-referenced regional version because of the country’s size and the high volume of cross-border employment with the United States. The statutory framework is Article 87 of the Federal Labor Law (Ley Federal del Trabajo, or LFT), which has been in force in its current form since 1970.

Statutory minimum: 15 days of the worker’s daily salary. The calculation is based on the daily wage at the time of payment, including base salary and any fixed compensation components (housing allowance, food allowance, transportation allowance, regular performance bonuses). Variable components (sales commission, irregular bonuses) are excluded unless they form part of the worker’s habitual remuneration.

Payment deadline: by 20 December each year. The payment must be made by this date regardless of whether the worker is still employed. Workers terminated during the year receive a proportional aguinaldo based on days worked.

Proportional calculation for partial years: workers who have not completed a full calendar year of service receive an aguinaldo proportional to days actually worked. The standard formula is: (Days worked in year / 365) × 15 days of daily salary. This applies to new hires during the year and to workers whose employment ended during the year (in which case the proportional aguinaldo is paid at termination, not waiting for 20 December).

Tax treatment: the first 30 days of UMA (Unidad de Medida y Actualización) value of aguinaldo is income-tax exempt in Mexico. For 2026, the UMA daily value is approximately 113.14 pesos, making the exempt amount approximately 3,394 pesos. Aguinaldo amounts above this threshold are subject to standard income tax withholding (ISR) and to IMSS (Instituto Mexicano del Seguro Social) social security contributions.

Above-minimum practice: many Mexican employers pay more than 15 days under collective bargaining agreements (contratos colectivos) or as competitive talent practice. Industry norms vary: 20 days is common in manufacturing and retail, 30 days is common in financial services, technology, and consulting, and 40+ days appears in senior management roles. The statutory minimum is the floor, not the market rate.

A worked example illustrates how the Mexican aguinaldo is calculated in practice. Consider a worker hired on 1 April 2026 in Mexico City at a monthly base salary of 25,000 pesos, with a 2,000 peso monthly food allowance (vales de despensa) included in habitual remuneration.

For a full-year worker on the same compensation package (12 full months), the gross aguinaldo would be 13,315 pesos (15 days × 887.67 daily rate). The proportional calculation in this example reflects the partial year (April-December) of service.

If the same employer paid an above-statutory 30 days of aguinaldo (a common practice in financial services and technology), the gross would scale linearly: full-year worker would receive 26,630 pesos gross; proportional partial-year worker would receive 20,061 pesos gross. The 30-day rate is approximately 2.4 percent of annual base salary, vs 1.2 percent at the 15-day statutory minimum.

Aguinaldo tax and social security treatment varies by country. The Mexican framework is the most-referenced and is detailed above. The following table summarises the major regional jurisdictions.

Mexico, Argentina, Ecuador, Guatemala, Peru, and Uruguay treat the aguinaldo as taxable income subject to standard withholding (with Mexico’s UMA threshold the most generous partial exemption). Bolivia, Costa Rica, and the Dominican Republic generally exempt the aguinaldo from income tax entirely. The tax position materially affects net cash flow to the worker and total cost to the employer, and should be factored into compensation modelling when entering each market.

Several common aguinaldo compliance failures recur across international employers hiring in Latin America. Each can result in labour inspectorate fines, individual worker back-payment claims, or in serious cases criminal liability for repeated non-payment.

1. Applying the wrong country formula. Mexico’s 15-day baseline is different from the one-month standard in most other regional jurisdictions. Foreign employers running global payroll often apply a uniform 13th-month calculation methodology and end up underpaying in countries that require a full month.

2. Missing the country-specific payment deadline. Deadlines vary materially: Nicaragua (10 December), Peru (15 December), Mexico (20 December), Ecuador (24 December), Paraguay (31 December). Globally consolidated December-31 payroll runs miss the earlier deadlines and trigger penalty exposure.

3. Excluding fixed allowances from the calculation base. In Mexico, food allowance (vales de despensa), housing allowance, and other fixed habitual compensation components must be included in the daily salary calculation. Excluding them produces under-payment.

4. Treating the aguinaldo as discretionary. The aguinaldo is a statutory entitlement, not a discretionary bonus. It cannot be waived by employee consent, absorbed into a higher base salary, or contingent on performance.

5. Failing to pay proportional aguinaldo at termination. Workers terminated during the year are entitled to a proportional aguinaldo based on days worked. The proportional payment is due at termination, not on the standard December deadline. Including this payment in standard severance is the operational fix.

6. Misapplying the UMA exemption in Mexico. The 30-day UMA threshold is income-tax exempt only, not social security exempt. The full aguinaldo amount is subject to IMSS contributions regardless of the UMA threshold. Employers sometimes calculate net pay incorrectly by applying the exemption to both ISR and IMSS.

7. Ignoring the two-instalment structure in Argentina, Uruguay, and Peru. These three countries split the annual aguinaldo into two payments at different deadlines. Globally consolidated December-only payroll misses the June payment entirely.

8. Forgetting Peru’s 9 percent extraordinary contribution. Peru’s Gratificación is paid alongside a 9 percent additional payment (Bonificación Extraordinaria) under Law 30334. Forgetting this addition produces under-payment relative to statutory requirement.

The aguinaldo is functionally similar to the broader concept of a 13th-month salary used in many other regions, but the specific rules differ enough that the two should not be conflated for compliance purposes. The Brazilian 13º salário (décimo terceiro) in particular has structurally different rules including a two-installment payment, mandatory withholding mechanics, and different inclusion of variable compensation.

The operational implication for international employers is that compensation modelling for Latin America should be done country-by-country, not regionally. A “13th month bonus” line item in a global compensation policy is too generic; the specific country implementation determines the formula, deadline, tax treatment, and inclusion rules.

The aguinaldo sits within a broader set of Latin American employment and compensation concepts that frequently come up together. Understanding the relationships helps employers structure compliant compensation packages.

13th Month Salary is the universal concept article covering year-end bonus mechanisms across all regions. The aguinaldo is the Spanish-speaking Latin American implementation of this broader concept.

13º Salário (Décimo Terceiro) is the Brazilian (Portuguese-speaking) version, operating under different CLT rules with a two-installment payment structure.

Employer of Record (EOR) arrangements for Latin America must handle aguinaldo compliance correctly as part of the local employment contract. Sophisticated EOR providers handle the country-by-country variation; less mature providers default to a generic 13th-month line item that may not match the specific country formula.

Prima Vacacional (Mexico) is a separate statutory entitlement under Article 80 LFT requiring a vacation premium of at least 25 percent of vacation salary, paid in addition to the regular vacation pay. The Prima Vacacional is distinct from the aguinaldo but commonly confused with it by foreign employers.

PTU (Participación de los Trabajadores en las Utilidades) in Mexico is the statutory profit-sharing payment, separate from both the aguinaldo and the Prima Vacacional. PTU is calculated based on company taxable income and distributed annually in May or June.
