## Recent Policy Updates You Should Know
- **Colombia**: After the 10 August 2026 earthquake, the government published draft decrees giving **special deadlines** for income tax and complementary taxes due in August for individuals and other taxpayers in affected municipalities. Also, suspends customs‐procedures deadlines in certain seccionales through 10 September. ([dian.gov.co](https://www.dian.gov.co/Prensa/Paginas/NG-Comunicado-de-Prensa-101-2026.aspx?utm_source=openai))
- **Argentina**: The deadline to file the **Ganancias y Bienes Personales** (Income and Wealth Tax) declaration for persons and undivided estates was **extended to 27 August 2026**. ([afip.gob.ar](https://afip.gob.ar/gananciasybienes/?utm_source=openai)) Additionally, for **autónomos** (self-employed workers), new contribution amounts took effect on **15 August 2026**. ([afip.gov.ar](https://www.afip.gov.ar/autonomos/?utm_source=openai))
- **Mexico**: The **Acuerdo 124/2026** published 13 August updates the **stimulus fiscal (tax incentive)** rates and special quotas for **special production and services tax (IEPS)** on certain fuels and diesel for the week of 15-21 August 2026.

## Actionable Compliance Steps for Taxpayers
- If you're in one of the **Colombian municipalities** affected by the quake and are due to file or pay income tax or do customs operations, **check the decrees**: you may get extended deadlines without fines or interest. Don’t assume deadlines based on calendar without verifying local domicile.
- Argentinian individuals with Ganancias/Bienes personales obligations: calendar moved—ensure filings are completed by **27 August**. Missing this may lead to fines or interest. Self-employed (autónomos) must update their contribution amounts starting **15 August**. Adjust your monthly budgeting accordingly.
- Mexican businesses or individuals dealing with fuel procurement or use should watch weekly IEPS stimulus schedules—fuel tax cost may change every week. For purchases of gasoline < 91 octanes or diesel, check your margins with new IEPS reductions.
## Preventing Surprise Penalties
- Always **verify official gazetteed or government site announcements**, especially following natural disasters—reliefs often come in emergency decrees or projects.
- Track changes to key tax rulebooks or codifications such as Colombia’s *Estatuto Tributario* (and its regulations like Decreto 898/2026) which affect subtle items like “interest presunto” or inflation components. ([normograma.dian.gov.co](https://normograma.dian.gov.co/dian/compilacion/docs/decreto_0898_2026.htm?utm_source=openai))
- In Argentina, regulatory updates like Law 27.802 (modifying treatment of certain investment income) affect residence or passive income tax—review these annually. ([biblioteca.afip.gob.ar](https://biblioteca.afip.gob.ar/dcp/LEY_C_027802_2026_02_27?utm_source=openai))
- In Mexico, the RMF (Resolución Miscelánea Fiscal) updates often mid-year—check the latest Anexos for forms, obligations, emission of digital invoices, etc. ([sat.gob.mx](https://www.sat.gob.mx/minisitio/NormatividadRMFyRGCE/index.html?utm_source=openai))
## Practical Checklist
- Λ Mark your country and sub-region for any **natural disaster** or emergency decrees; check if yours is included.
- Λ Build alerts for major government tax portals: DIAN (Colombia), AFIP (Argentina), SAT (Mexico), SII (Chile), SUNAT (Peru).
- Λ Budget for contributions or revised rates entering into force—e.g. in Argentina as of 15 August or deadlines in Colombia.
- Λ Use fiscal incentives when available (fuel stimulus in Mexico, emergency relief in Colombia).
**Bottom line**: Compliance means being aware of flattened deadlines, temporary reliefs, and weekly adjustments—not just annual tax season. Keep up-to-date with government announcements to stay ahead.
