If the IRS calls it a hobby, your losses disappear. That is not a slogan. It is section 183 of the tax code: activities not engaged in for profit. A side hustle that never shows a profit motive by objective facts does not get to dump unlimited losses onto a W-2. The kitchen-table brand, the Etsy store, the photography “business” that is mostly weekends and no books — those are where hobby vs business gets expensive.
The regulation is explicit. Greater weight goes to facts than to your statement of intent. A reasonable expectation of profit is not required, but the facts must show you entered or continued the activity with the objective of making a profit. Nine factors in Treas. Reg. §1.183-2 get used as a guide: how you run it, your expertise, the time and effort, expectation that assets will appreciate, success in other activities, history of income and losses, amount of occasional profits, your financial status, and elements of personal pleasure.
Hobby vs business is a facts test, not a logo test
An LLC and a pretty invoice do not finish the job. A separate bank account, real books, a price list, marketing that is not only friends, and changes you make when something loses money — those look like a trade or business. A drawer of receipts and a yearly loss that happens to shelter a salary look like a hobby. The IRS has seen the second one.
There is a presumption: if gross income exceeds deductions for three or more of the five consecutive years ending with the current year, the activity is presumed for-profit unless the IRS shows otherwise. Horse activities have a 2-of-7 variant. A presumption is not a shield if you never meant to make money. It is a starting point. People who “forget” to deposit cash and then claim a loss are not in this conversation. They are in a different one.
If it is a hobby, you generally cannot deduct the losses against other income the way a Schedule C business can. The Tax Cuts and Jobs Act’s treatment of miscellaneous itemized deductions already made hobby expenses a bad deal for many people. Confirm current-year rules with Publication 535 and a tax pro. Do not take a forum post as the Code.
Run it so a stranger would call it a business
- Separate account. Separate books. Invoices with due dates you actually chase.
- A written price, not “whatever they can pay” every time, unless discounting is a documented strategy.
- Time on the calendar that is production and selling, not only making.
- When a product loses money, change it or kill it. Pleasure without adjustment is a hobby signal.
- Profit some years. A decade of losses with a growing personal salary next door is a story the factors punish.
Home-office and other deductions still need a trade or business. Publication 587 will not save a hobby. Neither will a trademarked name.
Make profit the point, or stop calling it a write-off
There is nothing wrong with a hobby. There is something wrong with dressing one in Schedule C clothing. If you want the tax treatment of a business, accept the discipline of a business: records, prices, and a path to profit that a reasonable outsider could see. Hobby vs business is the IRS asking whether you are working or playing. Answer with the books.
Pleasure does not automatically kill a profit motive. The regulation says a sport or recreation can still be a business if the facts show you are in it for money. The problem is mixing a beloved craft with a salary-offset story and no change in behavior after years of red ink. If you would not keep doing it without the write-off, the factor about personal pleasure is not on your side.
Get a tax professional involved before you claim a string of losses, not after a letter arrives. Bring the books, the time log, and the price changes you made. Hobby vs business is easier to win with contemporaneous records than with a narrative you invent in April.
