The Régimen Simplificado de Confianza (RESICO) is a tax regime in Mexico designed to make tax compliance simpler and more beneficial for small taxpayers. It applies mainly to individuals with annual incomes under 3.5 million pesos, and allows them to pay income tax (ISR) at reduced rates while simplifying reporting and administrative requirements.
What is the RESICO Tax Regime?
RESICO was introduced to replace older regimes like the Tax Incorporation Regime (RIF) and to streamline how individuals and small businesses pay income tax. Its main goals are to:
- Offer lower ISR rates than the general regime (between 1% and 2.5% based on income levels).
- Automate tax calculations based on CFDI (Digital Tax Receipts) issued.
- Reduce burdensome paperwork, eliminating many formal accounting obligations.
- In recent years, the SAT has reinforced rules so taxpayers can take advantage of these benefits more easily.
For 2025 and onward, taxpayers under RESICO continue to benefit from simplified monthly payments of ISR, which for many taxpayers are considered final—meaning no annual tax return is required if you meet the regime’s rules.
Important RESICO Rules & Updates for 2025–2026
Here are key aspects you need to understand to remain compliant and avoid losing your status under RESICO:
1. Monthly Payments Are Definitive
If you comply and make your monthly payments on time, these are considered final for income tax purposes, and you may be exempt from filing an annual return under certain conditions.
2. Income Thresholds Still Apply
To qualify for or remain under RESICO, your annual income must stay below 3.5 million pesos. This includes income from wages, interest, services, rent, and other taxable activities.
In reforms around the 2026 tax package, special rules clarify how income from certain primary activities (like agriculture or livestock) is treated if it exceeds specific thresholds, meaning you pay ISR only on the excess.
3. Tax Mailbox and Electronic Signature Obligations
Having an active Buzón Tributario and e.firma is mandatory to receive SAT notifications and stay compliant, with deadlines established through 2026.
4. Proposed 2026 Tax Reforms Affecting RESICO
The 2026 tax reform under discussion includes several proposals that may be implemented:
- Exemption from annual tax return requirements for RESICO taxpayers, simplifying compliance further.
- Reduced penalties for RESICO taxpayers, similar to those in other simplified regimes.
- Extended deadlines for tax notifications to taxpayers, giving more time for legal and procedural steps.
These reforms aim to give RESICO taxpayers more clarity and reduce administrative burden as the regime continues into 2026.
Common Mistakes That Can Cost You Your RESICO Benefits
Despite its simplicity, many taxpayers lose access to RESICO due to avoidable errors:
1. Missing Three or More Monthly Payments
Failing to submit at least three monthly payments in a year—whether consecutive or not—may count as non-compliance under SAT rules. Regularly check your compliance status. (Avoid missing payments. Stay inside RESICO by paying monthly.)
2. Holding Company Shares or Partnerships
If you become a partner or shareholder in a company, you could be automatically excluded from RESICO. Individuals should avoid corporate relationships that jeopardize eligibility.
3. Exceeding the Income Limit
If your income goes above 3.5 million pesos in any year, RESICO status may be lost. Include all types of income—wages, interest, rent, and professional fees in your calculations.
4. Issuing CFDIs for Activities Outside RESICO
Generating official invoices (CFDI) for activities that are not covered by RESICO (for example, certain online platform sales or activities not registered with your RFC) could affect your eligibility.
5. Failing to Activate Your Tax Mailbox
This may seem simple, but not enabling your Buzón Tributario can lead to missed notices and loss of compliance.
Tips to Maximize Your RESICO Benefits
- Keep all monthly payments up to date.
- Ensure your RFC, e.firma, and tax mailbox remain active.
- Track your income throughout the year to prevent crossing the eligibility threshold.
- Regularly check your obligations and registered activities with the SAT.
- Use the SAT’s tools for calculating and paying taxes on time.
Staying informed is the best way to take advantage of RESICO’s simplified process and lower tax rates.
Summary: Why RESICO Still Matters in 2026
RESICO remains a highly beneficial regime for small taxpayers in Mexico, offering:
- Lower ISR rates.
- Simplified monthly tax compliance.
- Reduced reporting requirements.
- Potential future relief from annual filing obligations under tax reform.
As Mexico’s tax system evolves, staying compliant and understanding new rules will help you save on taxes and avoid unnecessary complications.
