How much is my aguinaldo?

Your pay, your days of aguinaldo and how much of the year you have worked: what you are owed before 20 December, and how much of it is taxed.

Your Christmas bonus (aguinaldo), before tax

$4,000

The law says it must be paid before 20 December.

Your monthly pay, before deductions (MXN) $8,000

Daily pay is the monthly pay divided by 30.

Days of aguinaldo 15

The law sets at least 15; your contract can give more.

Days worked this year 365

If you started this year, count the days from your start date to 31 December.

How much of it pays income tax

Tax-free	$3,519
Taxed (ISR)	$481

Federal Labour Law, art. 87: at least fifteen days of pay, before 20 December; if you did not work the whole year, the proportional part. LFT ↗

Tax-free up to 30 UMA: MX$3,519.30 in 2026 (UMA of MX$117.31 a day since Feb 1, 2026, INEGI). Income Tax Law art. 93 §XIV still says “minimum wage”; the SAT applies it as 30 UMA in its payroll guide. INEGI ↗

The calculation divides the monthly pay by 30, uses a 365-day year and does not work out the income tax on the taxed part.

What you learn here

The aguinaldo is a right, not a gift: the law asks for at least 15 days of pay before 20 December.
If you started working this year you are owed it too: the share for the days you worked.
Up to 30 UMA it pays no income tax; only the part above that is taxed, added to that month’s pay.
