How nonprofits trigger Unrelated Business Income Tax — a flat 21% federal levy, the three-part IRS test, traps in gift shops and advertising, statutory exclusions, and the post-2017 siloing rules under IRC §512(a)(6) that lock losses to each unrelated business.
Section 280A(g) — the Augusta Rule — lets business owners rent their personal residence to an S-corp, C-corp, or partnership for fewer than 15 days a year and exclude the entire rent from federal income tax.

The IRS applies a nine-factor test and a three-of-five-years safe harbor (two of seven for horses) to distinguish a real business from a hobby — here is what each factor weighs and how to document profit motive before an audit.
A 409A valuation is the IRS-recognized appraisal that sets the strike price on every option grant. Without one, founders risk 20% federal excise penalties, premium interest, and California's 5% piggyback tax — all falling on the employee.
U.S. cash balance pension plans let solo doctors, attorneys, and consultants deduct $100,000–$370,000 a year on top of a Solo 401(k). 2026 contribution limits, a worked example for a 54-year-old physician, and the actuarial commitments to weigh before signing.
