Overview: Argentine Entrepreneurs in the US Market
Argentina has one of Latin America's most vibrant tech and startup ecosystems. Buenos Aires has earned the nickname "Silicon Valley of South America," producing unicorns like MercadoLibre, Globant, Auth0, and Vercel. Argentine entrepreneurs increasingly form US LLCs to access the American market, receive payments in US dollars, and tap into the US venture capital ecosystem.
For many Argentine founders, a US LLC serves a dual purpose: accessing the world's largest consumer market and providing a stable business platform outside Argentina's volatile economic environment. With strict currency controls and high inflation, having a US-based entity with USD banking is particularly valuable.
However, operating a US entity from Argentina comes with specific IRS obligations. Unlike many countries, Argentina does not have a comprehensive income tax treaty with the United States, which means Argentine entrepreneurs face unique challenges in managing cross-border tax obligations.
No US-Argentina Tax Treaty
Argentina and the US do not have a comprehensive tax treaty. This means standard 30% withholding rates apply on US-source income like dividends, interest, and royalties. Proper planning is essential to manage your overall tax burden.
US Tax Requirements for Argentine Business Owners
As an Argentine entrepreneur with a US business entity, your tax obligations depend on your company structure, income sources, and whether you qualify as a US tax resident.
Form 5472 Requirements
Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation) must be filed annually by any US corporation or LLC that is at least 25% foreign-owned and has "reportable transactions" with foreign related parties.
For Argentine entrepreneurs, reportable transactions typically include:
- Capital contributions: Any money transferred from your Argentine or international accounts to your US company
- Loans: Funds borrowed from or lent to the company
- Service payments: Fees for services provided between you and the company
- Rent or royalties: Payments for intellectual property or equipment
- Sales of goods: Any inventory or assets sold between related parties
Even a single-member LLC with no business activity must file Form 5472 if there was any transaction between you (the foreign owner) and the LLC during the tax year.
Important: Stripe Atlas and Formation Services
Many Argentine entrepreneurs form US LLCs through Stripe Atlas, Firstbase, or doola. These services help with formation but typically don't handle ongoing IRS compliance. You still need to file Form 5472 and Form 1120 annually.
Form 1120 Requirements
If your US entity is classified as a corporation for tax purposes, you must file Form 1120 annually. This includes:
- C-Corporations: Standard corporations formed in any US state
- LLCs electing corporate taxation: LLCs that have filed Form 8832
- Foreign-owned disregarded entities: Single-member LLCs owned by foreign persons must file a pro-forma Form 1120 along with Form 5472
ITIN Application Process
An Individual Taxpayer Identification Number (ITIN) is required for Argentine citizens who need to file US tax returns but don't qualify for a Social Security Number.
| Feature | Argentine CUIT/CUIL | US ITIN |
|---|---|---|
| Purpose | Argentine tax & employment ID | US tax identification for non-residents |
| Format | 11 digits (XX-XXXXXXXX-X) | 9 digits (9XX-XX-XXXX) |
| Issued by | AFIP (Federal Tax Authority) | Internal Revenue Service (IRS) |
| Processing time | Immediate at registration | 7-11 weeks typically |
The ITIN application process involves:
- Complete Form W-7: The ITIN application form
- Provide proof of identity: Your Argentine passport (certified copy or original)
- Include supporting documentation: Your tax return or a letter explaining why you need the ITIN
- Submit via IRS or Acceptance Agent: You can mail directly to the IRS or use a Certifying Acceptance Agent (CAA)
No US-Argentina Tax Treaty
Unlike most major economies, Argentina does not have a comprehensive income tax treaty with the United States. This has significant implications:
| Income Type | With Treaty (e.g., UK) | Argentina (No Treaty) |
|---|---|---|
| Dividends | 5-15% | 30% |
| Interest | 0-15% | 30% |
| Royalties | 0-10% | 30% |
Key implications of no treaty:
- Full 30% withholding: US-source dividends, interest, and royalties are subject to 30% withholding with no reduction
- No permanent establishment protection: Without treaty protection, your US activities could create unexpected tax exposure
- Double taxation risk: Argentina taxes worldwide income, meaning the same income could be taxed in both countries
- Foreign tax credits: Argentina's AFIP may allow credits for US taxes paid, but the process requires careful documentation
Structuring Tip
Without treaty protection, the structure of your US entity becomes even more important. Many Argentine entrepreneurs use single-member LLCs (disregarded entities) to avoid corporate-level US taxation on non-US-source income. Consult a cross-border tax professional before choosing your entity structure.
Currency Controls & Challenges
Argentina's strict currency controls (known as "cepo cambiario") create unique challenges for entrepreneurs with US entities:
- Restrictions on USD purchases: Argentina limits how many dollars individuals can purchase through official channels
- Multiple exchange rates: The official rate, "blue dollar," MEP, and CCL rates create complexity in valuing transactions
- Mandatory repatriation: Certain export income must be converted to Argentine pesos through official channels
- AFIP reporting: Foreign bank accounts and entities must be reported to AFIP in your annual tax return (bienes personales)
- Tax on foreign assets: Argentina's "Impuesto sobre los Bienes Personales" taxes worldwide assets including your US LLC ownership
AFIP Reporting Required
As an Argentine tax resident, you must report your US LLC ownership, US bank accounts, and all foreign assets to AFIP. Failure to report can result in significant penalties and potential criminal charges. The personal property tax (bienes personales) may also apply to your US LLC interest.
Important Tax Deadlines
| Deadline | Filing Requirement | Notes |
|---|---|---|
| April 15, 2025 | Form 1120 & 5472 | For calendar year corporations |
| June 15, 2025 | Extended deadline for foreign filers | Automatic 2-month extension |
| June 2025 | Argentine income tax return (Ganancias) | Report worldwide income |
| June 2025 | Bienes Personales (personal property tax) | Report US LLC ownership |
| September 15, 2025 | Extended US returns | With Form 7004 filed |
Penalties for Non-Compliance
- Form 5472 penalty: $25,000 per form, per year for failure to file or filing an incomplete return
- Continued failure: Additional $25,000 for each 30-day period of non-compliance after IRS notice
- Form 1120 penalties: 5% of unpaid tax per month, up to 25% maximum
- Accuracy-related penalties: 20% of any underpayment due to negligence
Penalty Example
An Argentine entrepreneur who fails to file Form 5472 for three years could face $75,000 in penalties ($25,000 x 3 years), regardless of whether the business made any money.
State Tax Considerations
| State | State Income Tax | Annual Fee | Key Benefits |
|---|---|---|---|
| Delaware | None for out-of-state | $300/year | Business-friendly courts, established case law |
| Wyoming | None | $60/year | Lowest fees, strong privacy |
| New Mexico | None for out-of-state | $0/year | No annual report |
US Banking for Argentine Entrepreneurs
US banking is particularly important for Argentine entrepreneurs given currency controls. Here are your main options:
Online-First Banks:
- Mercury: Popular among Latin American founders, remote application available
- Relay: Accepts foreign-owned LLCs with straightforward onboarding
Fintech Alternatives:
- Wise Business: Provides US account details with excellent ARS-USD conversion
- Payoneer: Very popular in Argentina for receiving international payments
- dLocal: Argentine-founded fintech, good for regional payment processing
Banking Tip
Given Argentina's currency controls, many founders keep business funds in their US bank account and use Wise or Payoneer to transfer only what's needed to Argentina. This provides stability and avoids forced conversion to pesos at unfavorable official rates.
Common Mistakes to Avoid
- Ignoring Form 5472: Many Argentine entrepreneurs don't realize this form exists
- Not reporting to AFIP: Failing to declare US LLC ownership and foreign bank accounts
- Assuming treaty protection exists: There is no US-Argentina tax treaty
- Ignoring bienes personales: Your US LLC interest may be subject to Argentina's personal property tax
- Missing the initial filing: Your first tax return is due even if formed late in the year
- Not keeping transaction records: Document all transactions between yourself and your US company
- Assuming "no income = no filing": Zero-income companies still have filing obligations
- Currency control violations: Not complying with Argentine currency regulations regarding foreign income
