IMSS employee contributions are real but split across several sub-items with different bases and caps tied to the UMA, materially more complex than a single rate. Your real take-home will be somewhat below $258,580 once IMSS is deducted.
A $300,000 gross salary in Mexico has an estimated ISR take-home of $258,580 per year ($21,548 per month) for 2026, after $41,420 in federal ISR. IMSS employee contributions are not included, see below for why.

No. This is ISR (federal income tax) only. IMSS employee contributions are real but split across several sub-items with different bases and caps tied to the UMA, materially more complex than a flat rate, so this calculator excludes them rather than approximate a misleading number. Your real take-home will be somewhat lower than $258,580 once IMSS is deducted.
$300,000/year sits within the range nearshore tech employers (Mexican payroll or EOR) typically pay, though the exact competitiveness depends heavily on role, seniority, and city (Mexico City and Guadalajara/Monterrey command different bands). See our dedicated nearshore tech salary insight for city-level context.
No. Aguinaldo (the mandatory year-end bonus) and PTU (employee profit-sharing) are taxed under separate rules from ordinary monthly salary and aren't included in this $300,000 figure.
Mexico take-home figures use the 2026 SAT tarifa mensual (Anexo 8, Resolución Miscelánea Fiscal), applied monthly and annualized. Models federal ISR only; IMSS employee contributions, aguinaldo, PTU, and subsidio al empleo are excluded. Always confirm with the SAT or a tax professional for your exact position.
