SAT Announcement: 2026 Master Plan, what it means for foreingners and businesses operating in Mexico

Mexico’s Tax Administration Service (SAT) has announced its 2026 Master Plan, outlining the strategies that will guide the authority toward a historic tax collection goal of MXN 5.8 trillion, while strengthening tax enforcement and promoting a more transparent and approachable relationship with taxpayers.

For foreigners living, investing, or doing business in Mexico—and for sectors such as real estate, construction, non-profits, and structured businesses—this plan carries very real implications.

Here’s what you should know.

A more accessible—and more present—tax authority

One of the main pillars of the 2026 Master Plan is improved taxpayer service. SAT plans to:

• Open new offices in key states such as Jalisco, Quintana Roo, Baja California, Mexico City, Nuevo León, and Yucatán.

• Expand its Mobile Office program nationwide.

• Improve appointment systems, particularly for taxpayers under review or audit.

• Increase online procedures and simplify filing formats.

Why does this matter for foreign investors and companies?Greater accessibility also means greater oversight. SAT will have more visibility, more data cross-checking, and less tolerance for errors—especially those stemming from misunderstanding Mexican tax obligations.

Smarter, more targeted audits

SAT has announced that audits will be guided by objective and intelligent criteria, focusing on taxpayers with clear inconsistencies rather than those who comply properly.

This approach will likely prioritize:

• Unusual transaction patterns.

• Weak or poorly structured tax planning.

• Inconsistencies between reported income, invoicing, and tax returns.

• High-risk sectors such as real estate, construction, and professional services.

The takeaway: solid planning and proper documentation are no longer optional—they are essential.

Zero tolerance for fake invoices

The fight against fake or simulated invoices remains a top priority.

Under the 2026 Master Plan:

• SAT will intensify reviews to identify invoice trafficking schemes.

• Taxpayers who used invoices deemed fraudulent will have 30 days to correct their tax situation.

• Omitted taxes will be assessed and collected accordingly.

This is particularly relevant for:

• Developers and construction companies.

• Businesses using outsourced services.

• Non-profits that must ensure strict transparency of funds.
