Title 26 › Subtitle Subtitle A— - Income Taxes › Chapter CHAPTER 1— - NORMAL TAXES AND SURTAXES › Subchapter Subchapter B— - Computation of Taxable Income › Part PART VI— - ITEMIZED DEDUCTIONS FOR INDIVIDUALS AND CORPORATIONS › § 183
Limits tax deductions for activities an individual or S corporation does that are not run to make a profit. If an activity is not run for profit, you may only take two kinds of deductions: those you can take whether or not you mean to make money, and other business-type deductions only up to the amount that the activity’s gross income exceeds the first group of deductions. Definitions in one line: "activity not engaged in for profit" — an activity that is not treated as a trade or business or certain investment activities (so normal business-expense rules do not apply). If the activity shows a profit in at least 3 of 5 straight years, the IRS will assume you are trying to make a profit unless the IRS proves otherwise. For activities mainly involving breeding, training, showing, or racing horses, the test is profit in 2 of 7 years. You can elect to delay the IRS’s decision until after the fourth year (sixth for horse activities); if you do, the 3-in-5 (or 2-in-7) test applies to the whole period and the IRS gets two extra years after the filing deadline for the last year to assess any tax owed.
