Permanent establishment: when an Israeli company accidentally creates a US tax presence

Permanent establishment isn't about incorporation — it's about activity. A company that never registers a US entity can still create US tax exposure if someone is habitually negotiating and closing contracts on US soil on the company's behalf. The trigger is behavior, not paperwork.

The relevant question is whether a person is doing more than preparatory or auxiliary work — genuinely closing business, repeatedly, rather than just attending meetings or gathering information. The line is fact-specific, and companies routinely cross it without any single visible moment where it happened.

An Israeli B2B company hired a single US-based salesperson to close enterprise deals directly, with no US entity ever formed. Two years in, the pattern of that person's activity was enough to support a permanent establishment finding — meaning a portion of the company's profit could be attributed to the US and taxed there, retroactively, with no one having decided at any point to create that exposure.

The fix is rarely to stop selling in the US — it's to structure how the selling happens, and in some cases to form a US entity deliberately rather than let one exist in substance without existing on paper. The earlier this is addressed, the more options are actually available.
