Client reimbursements are gross income on Schedule C, and most states tax them even at zero markup — bill and book pass-throughs correctly.

Solo patent agents bill 30–50% below large-firm attorneys, but the discount only works with disciplined books — unearned fees held in a client trust account under 37 CFR 11.115, milestone-based flat-fee recognition, and per-matter profitability tracking across multi-year prosecutions.

U.S. nomads still owe worldwide income tax, the 2026 Foreign Earned Income Exclusion caps at $132,900 and never covers the 15.3% self-employment tax, the tax-home test disqualifies perpetual travelers, and FBAR triggers at $10,000 aggregated across all foreign accounts.
