Thousands of taxpayers deduct losses from activities that the IRS classifies as hobbies rather than businesses, often without realizing the distinction exists.

Founders routinely select their business structure based on convenience or early-stage advice—rarely with an eye toward what happens when a buyer eventually arrives.
