The RESICO Tax Regime in Mexico Explained
Navigating the Mexican tax system often feels like trying to find a specific house in a colonial town with no street signs—confusing, circular, and slightly overwhelming. I remember the absolute panic I felt during my first tax season in Playa del Carmen, staring at the SAT website and wondering if I was accidentally committing a felony. This guide meticulously breaks down the RESICO regime, providing the clarity you need to manage your Mexican obligations with confidence.

Understanding the RESICO Revolution for Expats
The introduction of the Régimen Simplificado de Confianza, or RESICO, fundamentally changed the landscape for foreigners living and working in Mexico. Before this regime existed, many of us were stuck in the "Actividad Empresarial" category, which required keeping meticulous track of every single deduction, from office chairs to printer ink, just to bring our effective tax rate down to something manageable.
What Exactly is Régimen Simplificado de Confianza
RESICO is a simplified tax regime designed for individual taxpayers (personas físicas) who have relatively straightforward business activities. In 2026, it remains the "golden ticket" for many expats because it shifts the focus from net income (income minus expenses) to gross income. Instead of paying tax on your profits after deductions, you pay a very small percentage on your total incoming revenue. This eliminates the stressful "deduction hunt" that used to define the end of every month for freelancers and small business owners in Mexico.
For those of us who have lived through the transition, the difference is night and day. You no longer need to beg for a "factura" every time you buy a cup of coffee for a client just to save a few pesos on your tax bill. Understanding Income Tax (ISR) in Mexico: How It Works is still important for context, but RESICO simplifies the math so significantly that it almost feels too good to be true.
Why the Mexican Government Created RESICO
The SAT (Servicio de Administración Tributaria) realized that the complexity of the old system was driving many people into the informal economy. By offering a ridiculously low tax rate—ranging from 1% to 2.5%—they made it more attractive for people to "get legal" than to stay under the radar. For the expat community, this was a massive win. It provided a clear path to residency and financial compliance without the overhead of a high-priced accounting firm for every minor transaction.
This shift was also about data. By moving everyone into a system where "facturas" are generated electronically for every peso earned, the government gained much better visibility into the economy. As an expat, participating in this system is one of the best ways to prove your "economic solvency" and "integration" if you ever decide to pursue Mexican Citizenship by Naturalization: The Process.
Transitioning from Traditional Tax Regimes
If you were already registered under the old RIF (Régimen de Incorporación Fiscal) or Actividad Empresarial, the transition to RESICO isn't always automatic. I’ve seen many friends get stuck in the old, higher-tax systems simply because they didn't "opt-in" or "check the box" during the right window. The SAT has become stricter about these transitions.
The transition requires a "Notice of Change of Economic Indicators" through the SAT portal. It sounds intimidating, but it is essentially just telling the government, "Hey, I qualify for the simpler version, please let me in." If you are just starting out, ensure your initial registration as a resident includes the correct regime selection. You can find more details on the initial setup in The RFC and SAT: Mexico's Tax System for Foreigners.
Eligibility and the 3.5 Million Peso Rule
One of the most frequent questions I get at expat meetups in San Miguel de Allende is, "Do I make too much money for RESICO?" The regime is designed for "small" taxpayers, but the definition of "small" in Mexico is actually quite generous for the average freelancer or remote worker.
Who Can Join the RESICO Club
To qualify for RESICO in 2026, your annual gross income must not exceed 3.5 million Mexican pesos. Given the current exchange rates, this is a significant amount of money—roughly $175,000 to $200,000 USD depending on the market. For most digital nomads, consultants, and local business owners (like those running a boutique hotel or a cafe), this limit is more than enough.
The regime covers four main types of income:
- Business activities (selling products, hardware, etc.).
- Professional services (consulting, teaching, coding).
- Leasing of real estate (renting out your condo or house).
- Primary sector activities (agriculture, fishing, etc.).
If your income comes from a foreign employer but you are a tax resident in Mexico, you can often still use RESICO, provided you are set up correctly. This is where using a service like Wise becomes essential for receiving those funds in a way that the SAT can track and you can easily report.
The Critical Exclusions You Need to Know
This is where things get tricky, and where I’ve seen expats get into hot water. You cannot be in RESICO if you are a shareholder or a partner in a "Moral Person" (a corporation). This means if you own a Mexican S.A. de C.V. for your business, you are barred from using RESICO for your individual taxes.
Furthermore, if you receive income from "tax havens" or if you have a relationship with a company that could be considered "related parties," you might be disqualified. I once knew a consultant who was kicked out of RESICO because he was technically a silent partner in his brother's Mexican construction company. The SAT’s systems are linked; they will find out.

Income Limits and Year-End Adjustments
What happens if you have a fantastic year and hit 3.6 million pesos? The moment you exceed the 3.5 million peso threshold, you are legally required to leave RESICO. The SAT will move you to the "Actividad Empresarial" regime, and here is the kicker: you may have to retroactively pay the higher tax rate for the entire year.
This is why "tax planning" isn't just for the ultra-wealthy. If you are nearing that 3.5 million limit in November, you need to be very careful about when you issue your final facturas for the year. I always tell people to keep a buffer. If you’re consistently earning near the limit, it might be safer to stay in the standard regime so you don't get hit with a massive, unexpected bill in April.
The Math Behind the 1% to 2.5% Tax Rates
Let’s talk about the actual numbers, because this is where the "magic" of RESICO happens. Under the standard tax regime, you could be paying up to 35% on your profits. Under RESICO, you are paying a maximum of 2.5% on your total income.
Breaking Down the Progressive Tax Table
The tax rate in RESICO is progressive, but even the "highest" bracket is incredibly low compared to most Western countries. The SAT calculates your monthly payment based on the total amount of "facturas" you issued that month.
| Monthly Income (MXN) | Tax Rate (%) |
|---|---|
| Up to 25,000 | 1.00% |
| 25,001 to 50,000 | 1.10% |
| 50,001 to 83,333 | 1.50% |
| 83,334 to 208,333 | 2.00% |
| 208,334 to 3,500,000 | 2.50% |
Imagine you earn 60,000 MXN in a month as a freelance graphic designer. Your tax bill would be roughly 900 MXN. That is less than the cost of a nice dinner for two in Mexico City. When you compare this to the tax rates in the US, Canada, or Europe, it becomes clear why RESICO is such a draw for the expat community.
Comparing RESICO vs Actividad Empresarial
In the "Actividad Empresarial" regime, you pay tax on your profit. If you earn 100,000 MXN but have 80,000 MXN in valid business expenses, you pay tax on 20,000 MXN. At a 20% rate, that’s 4,000 MXN.
In RESICO, you pay on the 100,000 MXN regardless of expenses. At a 2% rate, you pay 2,000 MXN. Even though you had high expenses, RESICO still wins. The only time RESICO might not be the best choice is if your business has extremely low margins (e.g., you spend 95 cents to make a dollar). For most service-based expats, RESICO is the undisputed champion. You can read more about the comparison in Income Tax (ISR) in Mexico: How It Works.
The Caveat of Deductions (or Lack Thereof)
The most important thing to remember—and the thing that most expats struggle to wrap their heads around—is that deductions do not matter for ISR (Income Tax) in RESICO. You cannot deduct your rent, your laptop, or your flights to see family. You pay on the "top line" (total income).
However, you still need to collect "facturas" for your expenses because of VAT (IVA). In Mexico, VAT is 16%. Even if you are in RESICO for income tax, you are still likely responsible for VAT. To offset the VAT you collect from clients, you need to show the VAT you paid on business expenses. This is a nuance many people miss. They think "No deductions means no facturas," but that’s a quick way to end up owing a lot of IVA.
Practical Compliance and the SAT Paperwork Trail
The low tax rates of RESICO are a "trust" agreement with the government. In exchange for the low rate, the government expects perfect compliance. If you miss a deadline, the SAT can (and will) kick you out of the regime and move you to a much more expensive one.
Getting Your RFC and e.firma Ready
Before you can even think about RESICO, you need your RFC (Registro Federal de Contribuyentes) and your e.firma (electronic signature). Getting an appointment at the SAT office has historically been a nightmare—I’ve spent many hours refreshing a browser at 2 AM just to find a slot in a city three hours away.
The e.firma is a set of files on a USB drive that acts as your legal signature for everything. Do not lose these files, and do not forget the password. Without them, you cannot file taxes, issue invoices, or communicate with the SAT. If you are starting from scratch, I highly recommend following the steps in How to Get an RFC in Mexico.
The Art of the Factura (CFDI 4.0)
In Mexico, an invoice is not just a PDF you make in Word. It is a "CFDI" (Comprobante Fiscal Digital por Internet), an encrypted XML file registered directly with the SAT. In 2026, we are using version 4.0, which requires the exact name and tax address of the recipient as it appears on their "Constancia de Situación Fiscal."
If you bill a client in the US or Europe, you still have to issue a "global" or "foreign" factura. If you don't issue a factura for the money hitting your bank account, the SAT considers that "unexplained wealth," which is a major red flag. Learning How to Issue a Factura (CFDI) in Mexico is probably the most important skill you will acquire as a self-employed expat here.
Monthly Filings and Annual Declarations
RESICO requires monthly filings by the 17th of the following month. The SAT portal usually auto-populates these based on the facturas you issued, which is a great feature—if the system is working. You also have to file an annual declaration in April.
One of the biggest mistakes I see is expats thinking that because their income is the same every month, they don't need to check the portal. Always log in. Check your "Buzón Tributario" (tax mailbox). The SAT sends official notifications there, and "I didn't see the email" is not a valid legal defense in Mexico.

Managing Foreign Income and Banking Logistics
For most of us, our clients aren't in Mexico. We are getting paid in Dollars, Euros, or Pounds. Managing the flow of that money into Mexico while staying compliant with RESICO is a delicate dance of exchange rates and bank transfers.
Receiving Payments from Abroad via Wise
When you receive foreign currency, the SAT wants to know the value in Pesos on the day the money hit your account. This is where a service like Wise is a lifesaver. You can receive your USD or CAD into your Wise account and then transfer it to your Mexican bank account when the rate is favorable.
When you issue your factura for this income, you must use the official exchange rate published by the Bank of Mexico (Banxico). Keeping your Wise statements organized is essential for your monthly filings. It provides a clear "paper trail" that matches the facturas you've issued to the foreign client.
Reporting Foreign Currency and Exchange Rates
The SAT is very specific about currency conversion. You cannot just use the "Google rate." You must use the "Tipo de Cambio" from the "Diario Oficial de la Federación" (DOF) from the day the payment was received.
If you receive $1,000 USD, and the DOF rate is 18.50, you must issue a factura for 18,500 MXN. If you eventually convert that money at a rate of 19.00, you have an "exchange gain," which technically should be accounted for. Most small RESICO taxpayers don't have to worry about minor fluctuations, but for larger amounts, it’s worth discussing with a specialist like those at Taxes for Expats.
Tax Treaties and Double Taxation Concerns
One of the biggest fears for Americans is paying tax twice. Thankfully, the US and Mexico have a robust tax treaty. Because RESICO taxes are so low, you will likely use the Foreign Tax Credit (FTC) on your US return, but you might still owe US taxes because the 1-2.5% you pay in Mexico doesn't fully "cover" your US tax liability.
This is a complex area. You are dealing with Mexican residency rules on one hand and the IRS on the other. It is vital to understand Do US Expats Living in Mexico Still Need to Pay US Taxes? to ensure you aren't leaving yourself open to an audit back home. Firms like Taxes for Expats are specifically geared toward helping you navigate this "dual-filing" nightmare.
Common Pitfalls and Expert Tips for Success
After years of helping people navigate this, I’ve seen the same mistakes made over and over. RESICO is simple, but it is not "set it and forget it."
The Danger of Missing a Single Filing
The SAT has zero tolerance for missed filings in RESICO. If you miss three monthly filings (consecutive or not) or fail to file your annual return, you are automatically disqualified. You will be moved to the "Régimen de Actividad Empresarial," and you cannot return to RESICO.
I know a guy in Tulum who lost his RESICO status because he went on a surfing trip in Indonesia and forgot to file for three months. His tax rate went from 1.5% to nearly 25% overnight. Treat your filing date like it’s the most important day of the month.
Working with Professional Accountants
Even though RESICO is "simplified," I still recommend hiring a local "contador." A good accountant in Mexico will cost you between 500 and 1,500 MXN per month for basic RESICO management. They will ensure your facturas are correct, your Buzón Tributario is clear, and your monthly "declaraciones" are filed on time.
Trying to DIY your Mexican taxes is like trying to fix your own plumbing in an old colonial house—you might think you’ve got it, but one wrong turn and you’ve got a massive mess on your hands.

When to Exit RESICO and Why
RESICO isn't always the end-all-be-all. If your business grows significantly and your expenses start to outpace your revenue, the inability to take deductions might start to hurt. Or, if you decide to take on partners and form a corporation, you will be legally forced out.
Also, for those of us from the US, it’s important to remember how these payments affect your Social Security and other home-country benefits. Balancing your Mexican tax strategy with your long-term goals is key. I always suggest keeping an eye on US Taxes for Americans Living in Mexico to make sure your global financial picture stays healthy.
