Why it matters for non-US founders
Three directions of PE risk, each a different problem:
- Your US LLC creates a PE in your home country. If you run day-to-day operations of the US LLC from your Dubai or Bengaluru apartment — making decisions, meeting clients, holding meetings — your home country’s tax authority may argue the US LLC has a PE there. The home country can then tax a share of the LLC’s profits attributable to the PE.
- You personally create a PE in the US. If you spend substantial time working in the US (even on a tourist visa), the IRS may argue you have a US PE, which brings US-source taxation and potentially US tax residency into play.
- Your UK/UAE/India business creates a PE in the US. Different fact pattern but same rulebook.
The specific triggers
PE criteria come from each applicable tax treaty, with common patterns:
- A fixed place of business — an office, a shop, a workshop, a mine. A home office can qualify if used regularly and the home country has aggressive PE guidance.
- A dependent agent who habitually concludes contracts on the company’s behalf.
- A project lasting more than a threshold (often 6 or 12 months) in the host country.
Why we route PE questions to the expert desk
PE analysis is treaty-specific and fact-intensive. The standard 5472 service is scoped to a non-US founder running the US LLC entirely from outside the US. If there’s any US activity (US employees, US office, substantial US time), that’s a PE question and needs an EA/CPA call before we file.
