What to Look at When Choosing an Entity
- Local incorporation vs branch/subsidiary: Incorporating locally exposes you to domestic compliance fully; using a branch may complicate repatriation and double tax.
- Accounting & inflation adjustments: Argentina uses inflation-adjusted accounting; failing to comply can lead to distorted financials and penalties.
- Access to incentives: Some countries offer tax credits or rate relief: Mexico’s Regularización Fiscal 2026 offers partial or total reduction of penalties, recargos for small businesses. (sat.gob.mx)
- Regime for small taxpayers: Mexico’s Régimen Simplificado, Chile’s smaller EIRL circunstances, or Argentina’s Monotributo can reduce compliance burdens.
Actionable Steps & Example Comparison
- If you’re launching a tech startup with revenue under threshold: in Mexico, consider setting up as persona física en Régimen Simplificado de Confianza to reduce ISR and compliance; Chile might favor SpA; Argentina Monotributo if under revenue ceiling.
- For international contracts or IP holding entities: Chile & Mexico offer treaty benefits; ensure entity’s operations justify its substance.
- Example: an Argentine business exporting software services might benefit from forming SRL, utilizing ARBA and AFIP compliance; but aligning times for annual Ganancias declaration and anticipo payments—note Argentina has extended Ganancias deadlines to 22 September 2026 for persons físicas y sucesiones indivisas.
