Year-1 total$0.00

Argentine SaaS founders can establish a Wyoming LLC to access US banking infrastructure and manage revenue in USD. This structure provides a legal framework for international operations while remaining distinct from local Argentine corporate entities.

The process involves state-level formation, obtaining an EIN from the IRS, and opening a Mercury account. Founders must maintain compliance with both US federal reporting requirements and Argentine tax regulations regarding foreign assets.

§ 02Tax residency · Argentine SaaS Founders

What the tax authority sees

US federal / local status

Wyoming LLCs are treated as pass-through entities for US federal tax purposes, where non-US owners are subject to US tax only on income effectively connected with a US trade or business (ETBUS).

Home-country rule

BCRA capital controls; USD hedging via US LLC common practice

Editorial verdict

Use the Wyoming LLC to hold USD revenue outside the Argentine banking system to hedge against local currency volatility, ensuring you maintain clean accounting for AFIP reporting.

§ 05Questions founders actually ask

FAQ

A Wyoming LLC is a US legal entity. While it allows you to hold funds in a US bank account like Mercury, you remain a tax resident of Argentina. You must declare your ownership and any income withdrawn from the LLC to the AFIP according to local regulations.
