How is ISR calculated in Mexico?

ISR (Income Tax) is calculated using a progressive table published in Annex 8 of the Tax Resolution. The lower limit is subtracted from taxable income, the corresponding percentage is applied to the excess, and the fixed fee is added. In RESICO, the rate is applied directly to income with no deductions.
