The Bottom Line
There is no dollar amount below which hobby income is exempt from federal tax. All of it is reportable — including amounts as small as a few dollars. What do exist are several threshold amounts where different rules kick in. None of them create an exemption; they just change what the rules require.
The most important thing to know up front: the $400 figure that circulates online is not a hobby income threshold. It belongs to a different rule entirely.
The $400 Confusion — Where It Comes From
This is where most people get turned around: the $400 threshold is a self-employment tax threshold, not a hobby income threshold.
It applies only to Schedule C business income. If an activity qualifies as a business and earns more than $400 in net profit, self-employment tax (15.3%) applies to that profit. Hobby income reported on Schedule 1 is never subject to self-employment tax — not at $400, not at any amount.
The $400 figure gets attached to hobby income because the same person often asks both questions at once: “Do I have a hobby or a business, and is there a minimum before I owe anything?” The answer to the first question changes everything about the second. Under hobby classification, the floor is $0 — all of it is reportable.
Example — Jordan’s Woodworking Sales
Jordan built and sold three cutting boards at a local market over the summer — a craft he’s been doing for years as a hobby. His total take was $340 in cash. No 1099 arrived. After reading online that “you don’t have to report under $400,” Jordan didn’t include it on his return.
The $400 rule Jordan read about applies to self-employment income on Schedule C. Because his woodworking is classified as a hobby — not a business — there is no minimum threshold. The $340 was reportable in full on Schedule 1, Line 8z.
The IRS wouldn’t necessarily know about the $340. But the reporting obligation existed regardless of whether a 1099 was issued.
How the Other Thresholds Work
These are the four trigger points that apply to hobby income. None of them are exemptions.
| Threshold | What It Triggers | Applies to Hobby Income? |
|---|---|---|
| $0 | Reporting obligation — all hobby income is reportable | ✅ Yes |
| $400 net profit | Self-employment tax (Schedule C only) | ❌ No — hobby income is never subject to SE tax |
| $600 | 1099-K / 1099-NEC issuance by payers and platforms | ✅ Yes — creates a matching record the IRS cross-references |
| 3-of-5 profit years | §183 Safe Harbor — activity presumed to be a business | ✅ Yes — determines whether hobby or business rules apply |
The $600 Threshold
Most people first encounter this threshold when a payment platform sends them a 1099-K — which happens when payments through the platform reach $600 or more in a calendar year. Separately, any payer who compensates a non-employee $600 or more for services is required to issue a 1099-NEC.
Receiving either form doesn’t change how the income is classified — hobby income stays hobby income regardless of which form arrives. What it does create is a matching record: income documented on a 1099 that doesn’t appear on a return can trigger a CP2000 notice from the IRS.
The 3-of-5 Year Safe Harbor
The most consequential “threshold” linked to hobby income isn’t a dollar amount. Under IRC §183(d), an activity that shows a profit in at least 3 of the last 5 consecutive tax years is presumed to be a business — which shifts the income from Schedule 1 to Schedule C, allows expense deductions, and adds self-employment tax on net profit.

Knowledge Check — Hobby Income Thresholds
Question 1: Jordan earned $340 selling handmade cutting boards as a hobby. No 1099 was issued. Is the $340 reportable?
- A) No — hobby income under $400 is below the IRS minimum
- B) No — income is only reportable when a 1099 is issued
- C) Yes — all hobby income is reportable regardless of amount or whether a 1099 arrived
Show answer
C. There is no minimum reporting threshold for hobby income. The $400 floor applies to self-employment tax on Schedule C business income only. The obligation to report hobby income exists independent of whether a 1099 was issued.
Question 2: Someone received a 1099-K from a payment platform for $800 in hobby-related sales. What does the 1099-K change about how the income is classified?
- A) It reclassifies the income as business income and requires Schedule C
- B) Nothing — the 1099-K documents what was paid; classification is determined by the facts of the activity, not the form
- C) It exempts the income from tax because the platform already withheld
Show answer
B. A 1099-K documents payments received — it doesn’t determine whether those payments are hobby or business income. Classification follows from the facts of the activity under IRC §183. The 1099-K matters because it creates a matching record: income that appears on a 1099 but not on a return can trigger a CP2000 notice.
What Happens When Hobby Income Goes Unreported
The IRS matches 1099s issued by platforms and payers against what filers report on their returns. When income documented on a 1099 doesn’t show up on a return, the IRS sends a CP2000 notice — a formal discrepancy notice that proposes changes to the return and asks for a response. It’s not an audit, but it does require a written reply.
Hobby income without a 1099 still needs to be reported — the obligation doesn’t come from the form, it comes from having received the income. The absence of a 1099 just means the IRS has less information to match against.
