What comes out — and what's added
From your gross salary, two things are withheld, and one is sometimes added:
- ISR — income tax under the SAT monthly tables, applied progressively.
- IMSS (worker share) — your contribution to social security (illness, disability, and more).
- Subsidio al empleo — a subsidy added back for lower earners, which raises your net.
Key point: a good net-salary calculator itemizes ISR, IMSS and the subsidy separately, using the current 2026 tables — not a rough percentage.
Why the 2026 tables matter
The SAT updates the ISR tables and the UMA (which drives several thresholds) each year. Using last year's numbers gives a wrong net. The 2026 figures reflect the updated tarifa and the current UMA.
No email wall
Many Mexican payroll sites hide the result behind a sign-up. You shouldn't have to give your email to see your own net salary — the calculation is straightforward once the current tables are applied.
