Working Legally in Mexico: RESICO and Freelancing
Mexico · Step by Step
Key Facts
- Permission first. Working for Mexican clients requires residency with work authorization (“permiso para trabajar”) — tourists may not.
- RESICO is the headline. The simplified regime taxes service income at roughly 1%–2.5% of gross receipts — among the lightest rates anywhere.
- Foreign clients, foreign payroll. Remote workers paid abroad sit in a different lane — the 183-day tax-residency rule still decides where you owe.
- Everything runs on facturas. The CFDI e-invoice, issued against your RFC, is how income officially exists.
- Get the contador. A Mexican accountant costs roughly MX$1,000–2,500 (US$55–135) a month and pays for itself in avoided mistakes.
You have the residency, the RFC and the bank account from earlier steps — this one turns them into a legal livelihood. Working legally in Mexico means matching your situation to the right tax regime, and for most expat freelancers the answer has a name: RESICO, one of the friendliest small-earner regimes in the world.
Step 1: Sort the permission question
Three situations, three answers. Working for Mexican clients or employers requires a residency card with work authorization — temporary residents request the “permiso para trabajar” notation (employer-sponsored cards include it; rentista-based cards typically don’t until you ask the INM to add it), while permanent residents work freely by right.
Remote workers paid by foreign companies occupy the famous gray-comfortable lane: no Mexican employer, no Mexican-source income, and Mexico’s practical concern is whether you become a tax resident — the 183-day rule covered in our tax guide. And tourists on an FMM may not work for Mexican payers, full stop.
Step 2: Meet RESICO, the expat freelancer’s regime
When you register your RFC for economic activity, the SAT assigns you a régimen — and the Régimen Simplificado de Confianza (RESICO) is the one to ask about. Open to individuals with gross receipts up to MX$3.5 million (about US$190,000) a year, it taxes gross income at roughly 1% to 2.5% — no deduction gymnastics, minimal bookkeeping, retention handled largely through the e-invoice system itself.
The trade: no deductions at all, and discipline requirements (file on time, stay current) that can eject you into the heavier general regime. For higher earners or deduction-heavy businesses, the alternative is persona física con actividad empresarial — progressive rates up to 35%, but every legitimate expense (with its factura) deducts.
Step 3: Learn the factura economy
Mexican taxation runs on the CFDI — the digital factura you issue clients for every payment, generated through the SAT system with your e-signature (e.firma) from the RFC step. Clients won’t pay invoices that aren’t facturas; expenses don’t deduct without one; the system cross-checks itself in real time.
Add IVA: services to Mexican clients generally carry 16% value-added tax, charged on top, declared monthly. This is exactly where the contador earns the fee — monthly declarations, factura hygiene and regime strategy for MX$1,000–2,500 (US$55–135) a month is the standard expat arrangement, and the consensus of everyone who tried the DIY route first.
Step 4: Keep the two systems straight
The recurring expat confusion is mixing the lanes. If you’re a Mexican tax resident (home and center of vital interests here, or 183-plus days), Mexico taxes your worldwide income — including the foreign clients — with treaty credits preventing true double taxation for Americans, Canadians and most Europeans (the US-Mexico treaty plus the foreign tax credit handle the overlap; US citizens file the IRS return regardless).
If you’re not a Mexican tax resident, Mexican-source income still owes Mexican tax — which is why working for local clients without an RFC is the line not to cross. The clean setup most working expats land on: residency with work permission, RFC under RESICO for any Mexican-source work, foreign income declared where the treaty says it belongs, contador on retainer, facturas for everything.
Boring, light, legal.
Frequently Asked Questions
Can I freelance for Mexican clients as a temporary resident?
Only with work authorization on your card — request the “permiso para trabajar” from the INM if your card lacks it. Permanent residents work by right.
What is RESICO and what does it cost me?
The simplified trust regime: gross service income up to MX$3.5 million (about US$190,000) a year taxed at roughly 1%–2.5%, with minimal bookkeeping — but no deductions.
Do remote workers with foreign clients need an RFC?
Not for the foreign work itself — but tax residency (183 days) can make Mexico tax that income anyway, and an RFC is needed for treaty-clean filing. See our Mexico tax guide.
What is a factura (CFDI)?
The official digital invoice issued through the SAT against your RFC. Income officially exists through it; expenses deduct only with it.
Do I really need an accountant?
At MX$1,000–2,500 (US$55–135) a month for declarations and regime strategy, the contador is the consensus best purchase of working-expat life in Mexico.
