Key Takeaways
- Argentine founders should start from default U.S. rules.
- The home-country file matters a great deal in a no-treaty structure.
- The U.S. LLC still needs a clean payee and owner-funding file.
- One shared cross-border file makes the structure easier to manage.
Argentine founders should expect the home-country file to matter a lot
Argentina is not on the current IRS treaty list, so the U.S. side often starts from default rules. That makes the residence-country reporting file more important because any relief or credit planning usually has to be handled locally rather than through a treaty shortcut.
The local side is not an afterthought here.
The U.S. LLC still needs a clean U.S. identity
Even in a no-treaty country, the U.S. LLC should have a consistent payee story, W-8 documentation where relevant, and a complete owner-funding ledger. Weak U.S. records make the no-treaty structure harder, not easier.
The entity still has to earn credibility.
Argentine founders should build one cross-border file, not two disconnected ones
Keep the U.S. documents, platform statements, and local reporting support together. That way the structure can be explained as one business rather than as two incompatible bookkeeping systems.
That is what keeps the year-end process manageable.

What should Argentine founders organize first?
