Key Takeaways
- The 90-day and $3,000 rule is narrow and depends on multiple conditions.
- Meeting one part of the rule does not mean the exception automatically applies.
- Exact U.S. days, compensation, and employer facts should be documented together.
- A short trip can still require careful analysis.
Short U.S. service trips are not automatically taxable, but the exception is narrow
The IRS exclusion page describes a specific rule under which compensation for personal services performed in the United States by a nonresident alien is not treated as U.S.-source income if three conditions are met. The period of presence, the compensation cap, and the foreign-employer requirement all matter. Founders often remember only one piece of that rule and then assume the trip is safe.
This exception is a checklist, not a vibe
A founder who spent fewer than 90 days in the U.S. may still fail the rule if the compensation exceeds the threshold or the employer side is wrong. Likewise, a founder working for a foreign employer may still fail if the U.S. presence is too long. The rule works only when the facts line up together.
Keep a trip memo while the details are fresh
If a founder thinks the exception may apply, the file should preserve exact days in the U.S., the compensation related to the U.S. services, and the employer relationship. That memo is far more useful than trying to rebuild the exception months later from memory.
Frequently Asked Questions
Is staying under 90 U.S. days enough by itself?
No. Other conditions also have to be met, including the compensation threshold and employer requirements.
Why should founders document compensation separately for short U.S. trips?
Because the exception depends in part on how much compensation relates to the U.S. services.
What is the biggest mistake with this rule?
Remembering one condition and forgetting that the rule is a multi-part test.
