Like many of us, you’ve probably dreamed of turning a hobby or avocation into a regular business. You won’t have any unusual tax headaches if your new business is profitable. However, if the new enterprise consistently generates losses (deductions exceed income), IRS may step in and say it’s a hobby–an activity not engaged in for profit–rather than a business.
What are the practical consequences? Under the so-called hobby loss rules, you’ll be able to claim those deductions that are available whether or not the enterprise is engaged in for profit (such as state and local property taxes). However, your deductions for business-type expenses (such as rent or advertising) will be limited to the excess of your gross income from the hobby over those expenses that are deductible whether or not the enterprise is engaged in for profit. Deductible hobby expenses are claimed on Schedule A of Form 1040 as miscellaneous itemized deductions subject to a 2%-of-AGI “floor.” By contrast, if the new enterprise isn’t affected by the hobby loss rules, all otherwise allowable expenses would be deductible on Schedule C, even if they exceeded income from the enterprise.
There are two ways to avoid the hobby loss rules. The first way is to show a profit in at least three out of five consecutive years (two out of seven years for breeding, training, showing, or racing horses). The second way is to run the venture in such a way as to show that you intend to turn it into a profit-maker, rather than operate it as a mere hobby. The IRS regs themselves say that the hobby loss rules won’t apply if the facts and circumstances show that you have a profit-making objective.
