How Does Mexican Tax Calculation Work?

Mexican invoices require precise calculation of IVA (Impuesto al Valor Agregado) at 16% standard rate or 8% for border zones. When companies pay independent professionals, they must also calculate ISR withholding (10%) and IVA retenido (2/3 of IVA). This free calculator handles all common Mexican tax scenarios including forward and reverse IVA calculation, ISR withholding, and multi-line invoice totals.
