What is Sueldo neto?
The sueldo bruto (gross salary) is the agreed salary before deductions. The sueldo neto (net salary) is what reaches the worker's account after ISR and the employee IMSS contribution are withheld.
Other deductions, such as repayment of an Infonavit loan or alimony payments, also reduce the net amount.
In practice
From $20,000 gross, after ISR and the employee IMSS contribution the worker receives around $16,900 of net salary.
