The IRS uses 9 factors to determine if your activity is a for-profit business (deductions allowed) or a hobby (deductions severely limited). Answer honestly — this is the exact IRS framework.
⚠️ What's at stake: If the IRS classifies your activity as a hobby, you cannot deduct losses against other income. You also can't carry forward losses from previous years. This can result in thousands in unexpected back taxes + penalties.
Answer each question about how you run your activity. Scoring: Yes = business indicator. No = hobby indicator.
1. Do you run this activity in a businesslike manner?
E.g., separate bank account, business cards, accurate books, written business plan.
2. Have you invested significant time and effort to make it profitable?
E.g., consistently working to grow revenue, taking courses, hiring help.
3. Do you depend on income from this activity for your livelihood?
E.g., it's your primary income source, or you're working to make it so.
4. Have you had profits in this activity in at least 3 of the last 5 years?
IRS "safe harbor": showing profit in 3 of 5 years creates a rebuttable presumption of for-profit intent.
5. Do you have losses? If so, are they due to startup costs or circumstances beyond your control?
Losses from getting started or from economic conditions are OK. Losses from personal lifestyle choices are not.
6. Have you changed your methods to improve profitability?
E.g., pivoted strategy, cut costs, changed marketing when results were poor.
7. Do you (or your advisors) have the expertise needed to run this as a business?
E.g., worked in the industry before, consulted with a CPA, attended relevant training.
8. Has the activity been profitable in the past, even if not recently?
Any history of profitability, even in early years, supports business intent.
9. Can you expect to make a future profit from the appreciation of assets used in the activity?
E.g., equipment, IP, or property used in the activity will likely appreciate in value.

Hobby loss rule: Under IRC § 183, if your activity is deemed a hobby, you can only deduct expenses up to the amount of income generated — you cannot create a loss to offset other income.
The 5-year safe harbor: If you show a profit in 3 of 5 consecutive years (2 of 7 for horse activities), the IRS presumes your activity is for-profit. File Form 5213 to trigger this safe harbor for new activities.
The 9 factors are not weighted equally — the IRS considers the totality of circumstances. Meeting 5 or more factors significantly strengthens your position.
Documentation is everything: Keep a business journal, save all receipts, maintain separate finances, and record marketing/improvement efforts. Paper trails win audits.
