IRS Audit Red Flag- Hobby or Business?

One of the most common IRS audit red flags is reporting large losses from an activity that appears to be a hobby rather than a legitimate business. The IRS closely monitors taxpayers who repeatedly claim losses on Schedule C or Schedule F to offset wages, investment income, or other taxable earnings. It's important to understand the difference between a hobby and a business. While any income you earn from a hobby is taxable and must be reported as "Other Income" on Schedule 1 of Form 1040, the expenses associated with that hobby generally are not deductible.

Prior to 2018, taxpayers who itemized their deductions could deduct hobby expenses up to the amount of hobby income as a miscellaneous itemized deduction, subject to certain limitations. The Tax Cuts and Jobs Act suspended that deduction through 2025, and the One Big Beautiful Bill Act permanently eliminated it. If you want to deduct losses on Schedule C, you must be able to demonstrate that your activity is a bona fide business. This means operating with continuity and regularity, maintaining accurate records, conducting the activity in a businesslike manner, and having a genuine profit motive.

The IRS also provides a helpful safe harbor rule. If your activity generates a profit in at least three out of five consecutive years—or two out of seven years for horse breeding activities—the IRS generally presumes you're operating a business for profit unless it can prove otherwise.

The bottom line? If you're claiming business losses year after year without ever turning a profit, make sure you have the documentation and facts to support your position. Taking the time to operate your activity like a true business can help reduce your audit risk and protect your deductions.
