Pay attention to the tax rules if you turn a hobby into a business

Many people dream of turning a hobby into a regular business. Perhaps you enjoy boating and would like to open a charter fishing business. Or maybe you’d like to turn your sewing or photography skills into an income-producing business.

You probably won’t have any tax headaches if your new business is profitable over a certain period of time. But what if the new enterprise consistently generates losses (your deductions exceed income) and you claim them on your tax return? You can generally deduct losses for expenses incurred in a bona fide business. However, the IRS may step in and say the venture is a hobby — an activity not engaged in for profit — rather than a business. Then you’ll be unable to deduct losses.

By contrast, if the new enterprise isn’t affected by the hobby loss rules, all otherwise allowable expenses are deductible, generally on Schedule C, even if they exceed income from the enterprise.

Important: Before 2018, deductible hobby expenses could be claimed as miscellaneous itemized deductions subject to a 2%-of-AGI “floor.” However, because miscellaneous deductions aren’t allowed from 2018 through 2025, deductible hobby expenses are effectively wiped out from 2018 through 2025.
