How your income fills the tax bands
Each slice of taxable income is taxed at its own rate, so only the part above a threshold pays the higher rate.

常见问题
How is ISR worked out?
From the monthly table in Article 96 of the Income Tax Law. Each band has a fixed fee plus a rate charged only on the part of your pay above that band’s lower limit, so moving up a band never costs you more than you gained.
What is the employment subsidy?
A credit against ISR for lower earners. Since 2025 it is a single flat amount — R$535.65 a month for 2026, which is 15.02% of the monthly UMA — for anyone earning up to $11,492.66 a month, replacing the old table of ten income ranges. Just past that limit it disappears entirely.
What does IMSS cost me?
About 2.375% of your contribution base salary, plus 0.4% on the part above three UMA, covering sickness and maternity, disability and life, and old age. Your employer pays considerably more on top of that.
What is not included?
Aguinaldo, vacation premium, profit sharing (PTU) and any voluntary retirement contributions, all of which are taxed under their own rules. This is the standard monthly withholding on salary.
