Mexico Christmas bonus calculator
The legal minimum bonus is fifteen days of salary, paid before 20 December.
It is not entirely tax free: only the first thirty UMA. Anything above that is taxed.
How it works
Take the daily salary -the monthly figure over thirty- and multiply by the days of bonus. If the year was not worked in full, it is shared in proportion to the days worked.
Thirty daily UMA of that amount are exempt. The excess is added to the month's salary to find the bracket and the difference in tax is charged.
Formula
Daily salary = monthly salary ÷ 30
Bonus = daily × days × (days worked ÷ 365)
Exempt = 30 × daily UMA
Taxable = bonus − exempt
Tax = tax(salary + taxable) − tax(salary)
Worked example
A salary of $15,000, 15 days of bonus, full year, in 2026:
Daily salary: $500
Bonus: $7,500
Exempt (30 × $117.31): $3,519.30
Taxable: $3,980.70 → tax of $763.11
You receive: $6,736.89
Explanation
Fifteen days is the <b>minimum</b>, not the norm. Many employers give thirty, some more; that is what the days field is for. What they cannot do is give less, or replace it with a gift or a voucher.
The thirty-UMA exemption is a flat figure and does not depend on your salary, so it shelters lower earners more: on $8,000 the bonus arrives almost whole, on $40,000 most of it is taxed.
Someone who joined mid-year still gets a bonus, in proportion to the days worked. Someone who has left collects it in the final settlement.
