Hobby or Business? How the IRS Tells the Difference
Updated October 26, 2026
Why the difference matters
Money from a hobby and money from a business are both income. The difference is in what you can subtract. A business can deduct ordinary and necessary expenses, such as supplies, software, and a share of your phone bill. Under current federal law, a hobby generally cannot deduct its expenses against the income it produces.
That is why the label matters. Two people can sell the same handmade items, and their tax results can be very different depending on how they run the activity.
Two quick examples
Picture a person who sells hand-knit scarves on weekends. She keeps a spreadsheet of yarn costs and sales, opened a separate bank account for the shop, raised her prices after checking what buyers would pay, and tracks whether the work turns a profit each year. That pattern looks like a business.
Now picture a person who paints for fun, sells the occasional canvas to friends, and has never tracked costs. The paintings are mostly for enjoyment, and the sales cover only a small part of the supplies. That pattern looks like a hobby. Both people owe tax on what they earn. Only the first one usually can deduct the costs of doing the work.

The factors the IRS looks at
The IRS does not use one single test. It looks at the whole picture, including these points from its guidance on hobby losses:
- Do you carry on the activity in a businesslike way, with records and a separate bank account?
- Do you have the skill or expertise the work needs, or are you learning it?
- Do you spend a lot of time on it, and do you work at it regularly?
- Do you expect the assets you use, such as equipment or property, to rise in value?
- Have you made a profit in similar activities in the past?
- Do you have a history of income or losses over several years?
- Do you get enjoyment from the activity, which points toward a hobby?
No single factor decides it. The pattern across several years usually tells the story.
The three-out-of-five shortcut
The tax code includes a helpful shortcut. If an activity makes a profit in at least three of five consecutive years, the IRS presumes it is a business. Losses in the first years are normal for a new business, because many take time to become profitable. What matters is whether you are working toward a profit and can show it.
If you do not meet the shortcut, the IRS still looks at the full set of facts. The rule simply gives you a clear target to aim for.
A quick self-check
Ask yourself a few honest questions. Do you keep a ledger of every sale and expense? Do you adjust prices and marketing to earn more? Would you stop if it lost money for three years in a row? If your answers show planning and a real goal of profit, you are probably running a business. If the activity is mostly for fun and the money is an extra, it may be a hobby.
Losses that keep repeating are a red flag. The IRS may question them if an activity shows losses year after year with no clear plan to turn a profit.
What to do if you are not sure
Start by keeping clean records from day one. Open a separate bank account for the activity, save receipts, and write down what you sell and what you spend. Clean records help you either way, because they show whether the work is steady and businesslike.
If the activity is a business, report it on Schedule C with your other self-employment income. If it is a hobby, report the income on the other income line and do not deduct the expenses against it. A tax preparer can help you pick the right answer for your facts before you file.
Mistakes that cost people money
The most common mistake is treating a hobby as a business to claim losses, then getting a notice later. The second is the reverse: a real business that leaves income off the return because it looked like a hobby. Both are fixable if you catch them early, but it is much easier to get the answer right the first time.
FAQ
Do I owe tax on hobby income?
Yes. Income from a hobby is taxable whether or not you call it a business. The difference is mainly what expenses you can deduct.
Can I deduct a loss from my hobby?
Under current federal law, hobby expenses are generally not deductible against hobby income, so a hobby loss usually cannot offset your other income.
How many years of losses is a red flag?
There is no fixed number. The IRS looks at the full pattern. Losses that repeat year after year with no real plan to profit draw the most attention.
Do I need a separate bank account?
It is not required, but it is one of the strongest signs of a businesslike activity and makes records much easier to keep.
Can a side business turn into a hobby later?
It can. If an activity stops being run in a businesslike way, or keeps losing money with no plan to improve, its status may change. Keep records every year so you can show what changed.
