If you run a business “on the side” and derive most of your income from another source, you may face a risk: Your enterprise might be a hobby in the eyes of the IRS. If so, it will be subject to the hobby loss rules, which means you can’t use a loss from the activity to offset other income. In evaluating whether an activity is a hobby, the IRS looks at various factors. For example, poor record keeping, ongoing lack of profit and minimal effort to make a profit might indicate a hobby. Concerned about the hobby loss rules? We can help evaluate your situation.
