If you sell handmade goods at craft fairs, breed dogs, give music lessons, or run a small Etsy shop, the IRS is aware of you — even if your income is modest. Hobby income has been taxable since before most people alive today were born, but the rules around deductions changed significantly in 2018. Understanding where the IRS draws the line between a hobby and a business, and what that means for your taxes, prevents unpleasant surprises at filing time.
This is not a reason to avoid hobby income. It is a reason to understand it before you earn it.
Hobby income is taxable
All income from hobby activities is gross income and must be reported on your federal tax return — regardless of how small the amount, regardless of whether you received a 1099, and regardless of whether the activity makes a profit. Report it on Schedule 1 of Form 1040, line 8j (Other Income).
There is no floor below which hobby income becomes nontaxable. The de minimis rules that apply to some other income types do not apply here.
The hobby loss rule: what changed in 2018
Before 2018, hobby expenses could be deducted up to the amount of hobby income as a miscellaneous itemized deduction, subject to the 2% AGI floor. That deduction was eliminated by the Tax Cuts and Jobs Act. It is currently suspended through tax year 2025 and may or may not be reinstated after that.
The practical result: hobby income is fully taxable, but hobby expenses are currently not deductible. If you spend $400 on supplies to make $600 in sales, you pay income tax on the full $600, not on the $200 profit.
This asymmetry is one of the main reasons people want their activity classified as a business rather than a hobby.
How the IRS distinguishes a hobby from a business
The IRS uses a facts-and-circumstances test based on nine factors. No single factor is decisive. The question is whether, overall, you are genuinely trying to make a profit.
The nine factors
- Do you conduct the activity in a businesslike manner? — maintaining separate books, keeping records, having a business bank account, and treating it like a business all weigh toward business status
- Do you put in the time and effort that a profit-seeking activity requires? — spending significant time on the activity, particularly if you have relevant expertise, weighs toward business status
- Do you depend on this income for your livelihood? — dependency on the income weighs toward business status; retirees with other income sources may weigh less heavily here
- Are your losses due to startup costs or circumstances beyond your control? — losses attributable to unusual circumstances or early-stage investment weigh toward business status; persistent losses with no plausible path to profit weigh against
- Have you changed your methods to improve profitability? — adjusting pricing, dropping unprofitable product lines, or changing suppliers in response to losses weighs toward business status
- Do you (or your advisors) have the knowledge needed to run this as a business? — relevant expertise supports a profit motive; lack of knowledge that one would be expected to acquire weighs against
- Have you made a profit from similar activities in the past? — prior profitable ventures in the same area support business status
- Does the activity produce a profit in some years? — actual profits, even occasional ones, support business status
- Do you expect the assets used in the activity to appreciate? — if the activity is building toward asset appreciation (breeding livestock, acquiring antiques, building a collection), that can support a profit motive even without operating profit
The profit presumption rule
There is a safe-harbor presumption: if your activity shows a profit in at least 3 of 5 consecutive tax years (2 of 7 for horse breeding and racing), the IRS presumes it is a business, not a hobby. This presumption can be rebutted by the IRS, but it shifts the burden of proof.
This is one reason keeping accurate records matters from year one. A small profit in year one — even a dollar — counts toward the three-of-five tally.
What happens if your activity is classified as a business
Business classification — filing a Schedule C — means your income and expenses are netted. If you have $600 in sales and $400 in legitimate business expenses, you pay income tax on $200 of profit, not on $600 of gross income.
The tradeoff: Schedule C income is subject to self-employment tax — 15.3 percent on the first $176,100 of net self-employment income in 2025, plus 2.9 percent above that. Half of self-employment tax is deductible from gross income. So business classification gives you expense deductions but adds self-employment tax obligations.
Whether business or hobby classification produces a better tax outcome depends on your specific numbers — the profit margin, your income tax bracket, and the amount of deductible expenses. For activities with thin margins and significant expenses, Schedule C can actually produce a lower total tax bill despite self-employment tax. For activities that are genuinely profitable with few expenses, hobby classification (when expenses are not deductible) may produce a similar bill. Run both calculations.
Specific activities and common questions
Selling handmade items (craft fairs, Etsy, local markets)
Income from selling handmade items — pottery, jewelry, woodworking, baked goods, textiles — is taxable whether sold in person or online. Platform 1099-K reporting thresholds have changed in recent years; check current thresholds before assuming no reporting obligation. Platforms like Etsy and PayPal are required to report payments above IRS thresholds to both you and the IRS.
Cost of goods sold (materials that went into the items you sold) is deductible on Schedule C if you are a business. Under hobby rules, it is currently not deductible.
Teaching or tutoring
Income from private instruction — music lessons, tutoring, art classes — is self-employment income even if informal and paid in cash. If you teach multiple students and earn more than $400 in net self-employment income, you file Schedule SE in addition to Schedule C. The Social Security earnings test applies.
Animal breeding
Dog breeding, horse racing, and similar activities receive special IRS scrutiny because they are common hobby-loss situations. The profit presumption window is 2 of 7 years rather than 3 of 5. Careful record-keeping — veterinary bills, feed costs, breeding fees — is particularly important.
Renting out equipment or property informally
Occasional rental of personal equipment (tools, musical instruments, cameras) or space (a garage, a storage area) generates taxable income. If the rental is sporadic and not marketed as a business, it may fall under hobby rules. If it is ongoing and marketed, Schedule C applies.
Short-term rental of a residence (Airbnb-type) has its own tax rules and is a separate category from hobby income.
How hobby income interacts with retirement benefits
Social Security earnings test
Net earnings from self-employment — including Schedule C income — count toward the Social Security earnings test if you are collecting before full retirement age. The 2026 limit is $24,480 for most of the year, and $65,160 in the year you reach full retirement age. Hobby income reported as Other Income on Schedule 1 (not Schedule C) does not count, because it is not self-employment income.
This distinction matters. If your activity is borderline, how you report it affects whether the income counts against your Social Security benefits.
IRMAA
Medicare Part B and Part D premiums are income-tested through IRMAA, which is based on modified adjusted gross income from two years prior. A strong year of hobby or self-employment income can raise your Medicare premiums two years later. If your hobby income is irregular — a good year followed by a typical year — track the impact in advance rather than being surprised when the IRMAA notice arrives.
Income-based benefits
Programs like Medicaid, SNAP, and LIHEAP use gross income calculations. Hobby income is generally counted as income for these programs. If you receive any income-based benefit, verify how self-employment or hobby income is treated under that specific program before earning it.

Recordkeeping that matters
Whether your activity is a hobby or a business, maintaining basic records from the start protects you:
- Income records — dates and amounts received, from whom, for what; bank deposits or payment app records serve this purpose if kept consistently
- Expense receipts — materials, supplies, equipment, fees; even if you cannot currently deduct them as hobby expenses, if the classification changes or the suspension lifts, you will want the documentation
- Profit and loss by year — a simple annual summary showing income minus expenses; this supports the three-of-five profit presumption and helps you see whether the activity is actually financially worthwhile
- Time logs — for the IRS’s “time and effort” factor, informal notes are better than nothing; they are useful if the activity is ever questioned
Common mistakes
- Not reporting small amounts — there is no taxable minimum for hobby income; a $150 craft fair sale is taxable, same as $15,000
- Assuming no 1099 means no reporting obligation — platforms only issue 1099-Ks above the applicable threshold; below-threshold income is still taxable and still reportable
- Deducting hobby expenses — attempting to deduct hobby expenses that are not currently deductible is a flag; if you want deductions, operate as a Schedule C business with the documentation to support it
- Conflating revenue with profit — total sales revenue minus materials minus platform fees minus shipping is your actual income; tracking this number prevents overestimating what the activity earns
- Ignoring estimated quarterly payments — if hobby income pushes your expected annual tax liability to $1,000 or more above withholding, estimated quarterly payments are required to avoid an underpayment penalty
Before your first taxable hobby sale
- Decide whether to operate as a hobby or a business — if you plan to deduct expenses, you need Schedule C and the documentation to support business status; if income will be modest and sporadic, hobby reporting may be simpler
- Open a separate account for activity income and expenses — this makes recordkeeping much simpler and supports a businesslike-manner argument if needed
- Track your income against the Social Security earnings limit if applicable — if you are collecting Social Security before full retirement age and will file Schedule C, know your annual limit
- Set aside a portion of each payment for taxes — 20 to 25 percent of hobby income is a reasonable reserve for most people; your actual rate depends on your tax bracket and whether self-employment tax applies
- Check whether estimated quarterly payments will be required — if you expect more than $1,000 in tax liability above withholding, calculate your first quarterly payment due date and amount before you earn more than that
