To report hobby income on your tax return, enter the total on Schedule 1 (Form 1040), Part I, Line 8j, labeled “Activity not engaged in for profit income.”1Internal Revenue Service. 2025 Schedule 1 (Form 1040) Additional Income and Adjustments to Income That amount rolls into the Part I total on Line 10 of Schedule 1, which then transfers to Line 8 of your Form 1040 and becomes part of your adjusted gross income. Federal law treats gross income as income from whatever source derived, and hobby earnings are no exception.2Office of the Law Revision Counsel. 26 US Code 61 – Gross Income Defined You owe tax on every dollar, and you cannot deduct the costs you incurred earning it.
The Exact Line on Schedule 1
Add up every dollar the hobby brought in during the year: cash, checks, payment app transfers, marketplace payouts, the value of anything you received in barter. Put the total on Line 8j of Schedule 1.
A common mistake in older write-ups is pointing people to Line 8i. That line is for prizes and awards, not hobby income. Using the wrong line won’t change what you owe, but it can create confusion when the IRS matches your return against the 1099 forms it received. After Line 8j, complete the rest of Part I, carry the total from Line 10 to Line 8 of Form 1040, and finish the return normally. Make sure the figure on Schedule 1 matches what shows up on the 1040. Mismatched numbers between the two forms are easy pickings for automated screening.
What Counts and Which 1099s to Expect
Everything the hobby earned counts, whether or not a form arrives in the mail. Two information returns show up most often.
A Form 1099-K comes from payment apps and online marketplaces when your total payments for goods or services through the platform exceed $20,000 and you had more than 200 transactions during the year.3Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill – Dollar Limit Reverts to $20,000 That threshold was reinstated after several years of planned reductions, so it’s the operative rule for 2025 and 2026 returns. A platform can still send a 1099-K voluntarily at lower amounts.
A Form 1099-NEC comes from a client or platform that paid you $600 or more for services during the year.4Internal Revenue Service. Reporting Payments to Independent Contractors Getting one doesn’t automatically mean the IRS considers you a business, but it does mean the agency has a record of that payment and expects to see it on your return.
Here is where people trip up: you report all hobby income even if no 1099 ever arrives. The forms are reporting mechanisms for payers, not permission slips for you. Cash from a craft fair, Venmo transfers for homemade candles, a swap with a neighbor — every dollar of value counts.
Why You Cannot Deduct Hobby Expenses
Before 2018, hobbyists could deduct expenses as miscellaneous itemized deductions subject to a 2% floor of adjusted gross income. The Tax Cuts and Jobs Act suspended that deduction starting in 2018, and the One, Big, Beautiful Bill Act, signed into law on July 4, 2025, made the elimination permanent.5Office of the Law Revision Counsel. 26 US Code 67 – 2-Percent Floor on Miscellaneous Itemized Deductions There is no expiration date to wait out.
The practical effect is harsh. Spend $3,000 on pottery supplies, sell $1,200 worth of bowls, and you owe tax on the full $1,200. Your $3,000 in costs does not reduce taxable income at all. No home office deduction, no depreciation, no write-off for materials. Every dollar of hobby revenue is fully taxable, even when the activity loses money overall.
If you consistently spend more than you earn and want those deductions back, the alternative is filing as a business on Schedule C, which requires meeting the IRS profit-motive test set out in Treasury Regulation § 1.183-2.6eCFR. 26 CFR 1.183-2 – Activity Not Engaged in for Profit Defined Business classification also brings self-employment tax with it, which is worth weighing before switching.
No Self-Employment Tax on Hobby Income
One genuine upside of hobby treatment: no self-employment tax. The 15.3% combined Social Security and Medicare tax applies to net earnings from a trade or business reported on Schedule C, and kicks in at $400 of net earnings.7Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Because hobby income lands on Schedule 1 rather than Schedule C, it bypasses that calculation.
You still owe regular income tax at your ordinary rate, but skipping the 15.3% is meaningful. On $5,000 of hobby income, that’s roughly $765 you’re not paying. It’s also one reason the IRS occasionally scrutinizes taxpayers who report income as a hobby when the facts look more like a business.
Do You Need to Make Estimated Payments
Nobody withholds tax from hobby earnings, so the bill can pile up by April. If you expect to owe $1,000 or more in total tax after withholding and credits, the IRS generally expects quarterly estimated payments using Form 1040-ES.8Internal Revenue Service. Estimated Taxes The quarterly deadlines fall in April, June, September, and January of the following year.
If you also hold a W-2 job, the simpler fix is filing a new W-4 and asking for additional withholding per paycheck. That covers the extra tax without quarterly paperwork. For larger or unpredictable hobby income, quarterly estimates are the safer route against an underpayment penalty.
What Happens If You Don’t Report
Skipping hobby income can trigger the accuracy-related penalty of 20% on the underpaid tax when the IRS finds negligence or a substantial understatement.9Internal Revenue Service. Accuracy-Related Penalty For individuals, an understatement is substantial when it exceeds the greater of 10% of the tax that should have been on the return or $5,000.10Office of the Law Revision Counsel. 26 US Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Interest runs on both the tax and the penalty.
The more common scenario isn’t a dramatic audit. It’s an automated CP2000 notice. When the IRS matches a 1099-K or 1099-NEC to your return and finds the income missing, it proposes additional tax, and interest runs back to the original due date. Reporting everything from the start, including small amounts, is the cleanest defense. The matching system is better than people assume.
How Long to Keep Records
Keep records supporting the return for three years from the date you filed or the due date, whichever is later. Underreport income by more than 25% of the gross income shown on the return and the window extends to six years. Don’t file at all and there’s no time limit.11Internal Revenue Service.
