## Introduction
Latin America’s tax systems are increasingly digital, and authorities are cracking down on compliance of filings, books, and record-keeping. These are the essentials to stay compliant across Mexico, Argentina, Chile, Colombia, and Peru.
## Electronic Books and Registries
- **Peru:** Important change under *Resolución de Superintendencia N° 0125-2026/SUNAT/RSNATI*—principal taxpayers (ingresos netos > 2,300 UIT) were supposed to use *Sistema Integrado de Registros Electrónicos* (SIRE). SUNAT has **extended discretion** for infractions covering June and July 2026, allowing taxpayers to **subsanear** (fix) without sanctions until August 31, 2026. ([cpe.sunat.gob.pe](https://cpe.sunat.gob.pe/node/141?utm_source=openai))
- **Chile:** Platforms must report online sellers’ payments; first **semianual** reports due end of August 2026, including sales and payments from October–December 2025 and Jan–June 2026. Failure means platform could be held responsible for VAT, and sellers missing obligations. ([sii.cl](https://www.sii.cl/normativa_legislacion/resoluciones/2025/reso93_anexo1.pdf?utm_source=openai))
## Deadlines & Extensions (Argentina Highlight)
- **AFIP** issued **Resolución General 5876/2026**, extending the deadline for individuals (personas humanas) and successions to file **Ganancias 2025** until **August 27, 2026**. It also deferred the first anticipo (prepayment) for 2026 to **September**, by CUIT series.

## Miscelánea Fiscal Mexico & Buzón Tributario Windows
- In Mexico, via **Buzón Tributario**, any **trámite, promoción, solicitud o aclaración** presented between **July 20–31, 2026** in this channel will be considered received **August 3, 2026** due to non-business days. This affects deadlines around the end of July. ([wwwnp.sat.gob.mx](https://wwwnp.sat.gob.mx/minisitio/BuzonTributario/index.html?utm_source=openai))
- Also, key elements of tax forms and security codes (e.g. **Anexo 26 codigos de seguridad en cajetillas de cigarros**) under **Resolución Miscelánea Fiscal RMF 2026** have changes effective **August 1, 2026**. ([sat.gob.mx](https://www.sat.gob.mx/minisitio/NormatividadRMFyRGCE/documentos2026/rmf/rmf/1aRM_RMF2026.pdf?utm_source=openai))
## Practical Steps to Compliance
1. **Mark the new deadlines.** Argentina: August 27 for Ganancias 2025; Mexico: August dates in Buzón Tributario; Peru: August 31 for rectification of SIRE related infractions.
2. **Evaluate whether electronic systems like SIRE or digital platform reporting apply to you.** If bulk of income is platform-based, double-check platform’s reporting to avoid liability.
3. **Check CUIT / RUT / RFC series**—many deadlines slide by taxpayer identifier.
4. **Use grace periods and extensions** effectively, but don’t assume they’ll be renewed—build compliance into your calendar.
## Common Penalty Risks & Avoidance
- Delays in filing or payment: fixed fines or interest charged daily.
- Use of informal or cash-only systems without formal receipt issuance.
- Unreported income from digital platforms or foreign sources when taxable under residency rules.
- Incomplete electronic records or failure to migrate to mandated systems (e.g. SIRE in Peru, Libro IVA Digital in Argentina).
## Conclusion
Compliance in Latin America is shaped by evolving digital systems and frequent regulatory updates. To stay clear of penalties, **stay informed** about extensions and rule changes, **formalize** your record-keeping, and use grace periods while stepping up compliance infrastructure.
