Why LATAM is the next big hiring corridor for US companies
Latin America has become the default near-shore contractor pool for US companies. Time zone alignment with the US (Eastern, Central, and Mountain align well with most of LATAM), strong engineering and design talent, and competitive rates have made Mexico, Brazil, Argentina, and Colombia particularly attractive.
The compliance landscape is more fragmented than India or the Philippines, however. Three of the four countries have no US tax treaty. Each has its own tax authority, registration system, and invoicing requirements. This guide breaks down what a US company needs to know for each of the big four.
The US side: identical across all four countries
Regardless of whether your contractor is in Mexico City, São Paulo, Buenos Aires, or Bogotá, the US side of the transaction looks the same.
Collect a W-8BEN
Before the first payment, the contractor must complete Form W-8BEN (individual) or Form W-8BEN-E (entity). The form documents foreign status and beneficial ownership.
Confirm services performed outside the US
Under IRS source of income rules for personal services, services income is sourced to the place where the work is physically performed. A Mexico-based contractor working remotely earns Mexican source income for US tax purposes, not US source income.
If the contractor visits the US for a sprint or onsite, that portion becomes US source and is subject to NRA withholding rules. The statutory rate is 30 percent under IRC sections 1441 through 1443, unless reduced by treaty.
Treaty coverage is uneven across LATAM
Here is the part that surprises many US founders. As of 2026, the US has only one income tax treaty with a major LATAM economy in force: Mexico.
The US has no income tax treaty with Brazil, Argentina, or Colombia.
The US-Chile treaty entered into force, but that is the only other major LATAM treaty in scope.
This matters when there is US source income. Without a treaty, the contractor faces the full 30 percent statutory withholding rate on US source FDAP income with no treaty reduction available. For services performed entirely outside the US, this is a non-issue because the foreign source treatment removes the US withholding right in the first place.
Mexico: SAT, RFC, CFDI
The Mexican tax administration is SAT, the Servicio de Administración Tributaria. Every working person in Mexico must have an RFC, the Registro Federal de Contribuyentes, regardless of citizenship.
For an independent professional (Persona Física con Actividad Empresarial), the RFC is registered with the SAT. The registration determines the contractor’s tax regime, which dictates the rates and obligations.
The simplified regime for individuals is RESICO (Régimen Simplificado de Confianza). RESICO applies to individuals with annual income up to MXN 3.5 million and uses graduated rates tied to income brackets.
For US payers, the relevant Mexican output is CFDI invoicing. The Mexican government requires every commercial transaction to be invoiced via CFDI, the electronic invoice that SAT validates in real time. The contractor issues a CFDI 4.0 for each payment from you and provides it for your records (optional for you, mandatory for the contractor).
US-Mexico treaty: Article 14 and the 183-day rule
The US-Mexico Income Tax Convention governs cross-border taxation. The Treasury technical explanation walks through each article.
Article 14 covers independent personal services. A Mexican resident’s services income is taxable in the US only if the contractor has a fixed base in the US or is present in the US for more than 183 days in a twelve-month period. For a Mexican contractor performing all work in Mexico and visiting the US only briefly, the treaty supports the foreign source treatment under domestic US law.
When US source income does arise, the contractor files Form 8233 to claim treaty exemption for services.
Brazil: Receita Federal, CPF, MEI, autônomo
The Brazilian tax authority is Receita Federal. Every Brazilian resident has a CPF, the Cadastro de Pessoas Físicas, which is the individual tax identification number.
Brazilian contractors operate in one of two regimes for tax purposes.
MEI (Microempreendedor Individual) is the simplified regime for individuals with annual gross revenue up to BRL 81,000. MEIs pay a fixed monthly tax via DAS (Documento de Arrecadação do Simples Nacional) covering INSS, ISS, and ICMS depending on the activity. Annual filing is the DASN-SIMEI declaration, due by May 31 of the year after the reporting year.
Autônomo is the unincorporated self-employed status for individuals who exceed MEI limits or perform services outside the MEI eligible activity list. Autônomos file the annual IRPF (Imposto de Renda Pessoa Física) return through Receita Federal, due in late April each year, when annual income exceeds the filing threshold.
No US-Brazil tax treaty exists as of 2026, so all the US side is governed by domestic IRS rules. For pure offshore services performed in Brazil, the foreign source rule applies and no US withholding is required.
Argentina: AFIP/ARCA and Monotributo
Argentina’s tax administration is AFIP, now operating under the ARCA name in some 2026 contexts. The simplified regime for self-employed individuals is Monotributo, which combines income tax, VAT (IVA), pension contributions, and social health contributions into a single monthly payment.
Monotributo has categories from A to K, with income thresholds and monthly amounts updated periodically by AFIP to reflect Argentina’s inflation. Service providers can register up through approximately Category H. Above that ceiling, the contractor moves to the general regime with separate income tax and IVA registration.
Argentina has no US tax treaty. For pure offshore services, this is a non-issue because no US source income arises.
Argentina has currency controls that can complicate FX receipt. The official exchange rate (BCRA peso) and the parallel rates have diverged significantly in recent years. Most Argentine freelancers receiving USD work for US clients use specialist FX rails or maintain USD holdings outside the local banking system.
Colombia: DIAN and RUT
The Colombian tax authority is DIAN, the Dirección de Impuestos y Aduanas Nacionales. Every taxpayer must register and obtain a RUT (Registro Único Tributario), which contains the NIT (Número de Identificación Tributaria).
Colombian independent contractors self-report income annually to DIAN. Foreign companies are generally not required to withhold Colombian taxes when paying contractors in Colombia.
Colombian contractors are required to contribute to the General Social Security System on a monthly basis. Recent reforms under Law 2381 of 2024 (the Colombian Pension Reform) introduce a phased contribution requirement depending on contract type and income level. The administration of these contributions sits with the contractor, not the US payer.
Colombia has no US tax treaty. For pure offshore services, the foreign source rule under US law applies.
Payment rail selection across LATAM
LATAM corridors have higher FX margins than developed-market corridors. The choice of rail can drive a 2 to 5 percentage point swing in net amounts received.
Wise. Works for Mexico, Brazil, and Colombia. Argentina coverage is limited and depends on regulatory status. Wise quotes mid-market plus a transparent margin (typically 0.5 to 1 percent for these corridors). Settlement in one to three business days.
Payoneer. Strong coverage across all four countries. Common for contractors who source US work through marketplaces.
Stripe Connect. Works in Mexico, Brazil, and Colombia with local payout support. Useful for platform-style payments.
SWIFT international wire. Universal coverage. Higher cost (sender fee plus intermediary deductions plus 2 to 4 percent local FX margin). Best for one-off larger payments.
Brazil-specific: PIX. Brazil’s instant payment system PIX was launched by the Banco Central do Brasil on November 16, 2020 in full operation. PIX is domestic to Brazil but is increasingly bridged by payment platforms for cross-border cases.
For ongoing LATAM relationships, Wise or Payoneer typically wins on price and speed. SWIFT is reasonable for occasional larger payments.
Misclassification risk across the four
Each jurisdiction has its own employment test, but the substance is similar.
Mexico. The Federal Labor Law (Ley Federal del Trabajo) uses a subordination test. If the contractor effectively works under the company’s direction, the relationship can be reclassified as employment with back wages, social charges, and severance liability.
Brazil. The CLT (Consolidação das Leis do Trabalho) uses a four-element test: personal performance, subordination, habitually performed work, and onerosidade (compensation). Brazil is one of the more aggressive jurisdictions on misclassification, with significant back-liability exposure.
Argentina. The LCT (Ley de Contrato de Trabajo) presumes an employment relationship when the worker is personally performing services for another in a dependent capacity. The contractor’s burden of proof for independent status is high.
Colombia. The Substantive Labor Code uses a similar control-and-subordination test. Recent reforms have tightened the scrutiny on long-term contractor relationships.
The mitigations are consistent across all four: deliverables-based SOW, evidence of multiple clients, autonomy over working methods, and periodic review of the relationship.
A clean onboarding workflow for any LATAM contractor
- Confirm the contractor is locally registered (RFC, CPF, Monotributo, RUT).
- Send the contractor an SOW with country-appropriate clauses on IP, governing law, and dispute resolution.
- Collect a signed W-8BEN. Refresh every three years.
- Pick a payment rail. Wise or Payoneer for most cases. SWIFT for larger one-off payments.
- Pay the invoice on the agreed schedule. Keep contracts, invoices, payment receipts, and W-8 together.
- Review the engagement quarterly for misclassification risk.

When a platform pays for itself
A US company paying a single Mexican contractor can do this manually. Past three or four contractors across two or more LATAM countries, the administrative overhead (different invoicing rules, different FX corridors, different misclassification tests) makes a platform meaningfully cheaper than DIY.

Pulling it together
LATAM is the cleanest near-shore contractor corridor for most US companies. The US tax side is simple once you confirm the work is performed offshore and collect the W-8BEN. The local side lives with the contractor.
The complexity that does arise comes from FX corridor pricing and misclassification scrutiny in jurisdictions like Brazil and Argentina, which are aggressive on labor reclassification. A platform that bakes country-appropriate SOW clauses into the workflow removes most of this friction.
