Hobby vs Business: When the IRS Cares About the Difference
If the IRS calls your side activity a hobby, you still pay tax on every dollar of income but you cannot deduct the expenses. Here is how the IRS tells a hobby from a business and how to land on the right side of the line.
You started selling your woodworking, or your photos, or your homemade candles, and now you are wondering how the IRS sees it. The hobby versus business question matters more than it sounds, because the tax treatment is lopsided. A business can deduct its expenses and even report a loss. A hobby pays tax on all of its income and deducts nothing. Knowing which side you are on, and how to get to the better side, is worth real money.
Why the label matters so much
If your activity is a business, you report it on Schedule C, deduct your ordinary and necessary expenses, and if you spent more than you brought in, that loss can offset your other income. If it is a hobby, the income is fully taxable as other income, but the expenses are not deductible at all right now. So a hobby really is the worst of both worlds: money in, nothing to offset it.
People sometimes assume the expense deductions for hobbies will come back. They will not. The suspension that took them away has been made permanent, so there is no future year where hobby expenses quietly return.
How the IRS decides
The core question is whether you are genuinely trying to make a profit. There is no single test, the IRS weighs a list of factors together, including:
- Whether you run it in a businesslike way and keep real books.
- Your expertise, or your reliance on advisors who have it.
- The time and effort you put in.
- Whether you depend on the income.
- Your history of profits and losses, and whether losses are normal startup losses or ongoing.
- How much personal pleasure or recreation is involved.
The three-of-five-year safe harbor
There is a helpful presumption. If your activity shows a profit in at least three of the last five years, the IRS presumes it is a real business and the burden flips to them to argue otherwise. For activities involving horses, the test is two of seven years. Falling short does not automatically make you a hobby, but it does mean you should be ready to show your profit motive.
How to land on the business side
Most of the factors come down to acting like a business. Keep separate records, track income and expenses, have a plan for turning a profit, and document the steps you take to improve. The same habits that make you look like a business to the IRS also happen to be the habits that actually help you become profitable.

Frequently asked questions
Do I have to pay tax on hobby income?
Yes. All income from a hobby is taxable and gets reported as other income on your return, even though you cannot deduct the expenses against it. There is no minimum that makes hobby income tax-free.
Can I deduct hobby expenses?
No. Since 2018 the expense deductions that used to offset hobby income have been suspended, and that suspension is now permanent. So a hobby is the worst of both worlds for tax, income in but no expenses out.
How does the IRS decide if I have a business or a hobby?
It looks at whether you genuinely intend to make a profit, using a list of factors like whether you run it in a businesslike way, keep books, have expertise, and depend on the income. No single factor decides it.
What is the three-of-five-year rule?
If your activity turns a profit in at least three of the last five years, the IRS presumes it is a real business rather than a hobby. For activities involving horses the test is two of seven years. Failing it does not automatically make you a hobby, but it shifts the burden onto you.
Do I pay self-employment tax on hobby income?
No. Because a hobby is not a trade or business, the income goes on Schedule 1 as other income, not on Schedule C, so it is not hit with self-employment tax. The trade-off is that you also cannot deduct any costs.
