How the math works

ISR: the 2026 monthly tariff (Art. 96 LISR) is applied to your gross salary. For example, $20,000 falls in the $17,533.65-$35,362.83 bracket: 21.36% on the excess over $17,533.65 plus $1,856.84 fixed = $2,383.65.

Subsidio al empleo: $535.65/month applies when gross income is up to $11,492.66. It reduces ISR to zero but is never paid out in cash.

IMSS (employee): 1.125% cesantia y vejez + 0.625% invalidez y vida + 0.375% gastos medicos pensionados + 0.25% prestaciones en dinero + 0.40% enfermedad y maternidad (only on the amount exceeding 3 UMA daily).

Net = gross - ISR + subsidio - IMSS

Tax tables verified: October 2026. Sources: SAT (Anexo 8, RMF 2026), IMSS (LSS Arts. 106-108, 147, 168).

Does this include INFONAVIT?
No. INFONAVIT housing fund deductions depend on your specific credit and are not included.
What if I earn minimum wage?
Workers earning exactly the minimum wage pay no employee IMSS share - the employer absorbs it (Art. 36 LSS). This calculator applies standard rates.

How it works

Quick answer: A monthly gross salary of $20,000 MXN nets about $17,104.14 after 2026 ISR ($2,383.65) and the employee IMSS share ($512.21).

Formula

ISR = (gross − lower limit) × marginal rate + fixed fee  (SAT 2026 monthly tariff)
Net ISR = ISR − subsidio al empleo ($535.65 if gross ≤ $11,492.66)
IMSS ≈ 2.375% of salary + 0.40% of the part above 3 UMA ($10,698.66)

Assumes the base salary for contributions (SBC) equals the gross monthly salary.
