Overview

• In Mexico, Article 87 of the Federal Labor Law guarantees an annual aguinaldo of at least 15 days’ pay to be paid no later than December 20, and there is no approved increase to a 30‑day minimum for 2025.
• Mexican workers who served less than a year receive a proportional payment, commonly calculated from daily pay (monthly salary ÷ 30), multiplied by 15, divided by 365 and then by days worked, with BBVA offering an online calculator.
• If the aguinaldo in Mexico is unpaid or underpaid by the deadline, workers can file a report with the Procuraduría Federal de la Defensa del Trabajo (Profedet) to trigger an investigation.
• In Argentina, the December Sueldo Anual Complementario equals 50% of the highest gross monthly salary earned between July and December and must be paid by December 18, with many employers advancing the payment and a four‑business‑day window to regularize without sanctions.
• Argentina’s domestic workers covered by Law 26.844 calculate the December installment on the semester’s best month using October 2025 wage scales, include remunerative add‑ons like seniority or zone, and receive a proportional amount if they worked only part of the semester.
