The Bottom Line on LLCs for Hobby Income
An LLC does one thing a sole proprietorship does not: it puts a legal wall between the activity and your personal finances. It does not lower your tax rate or eliminate self-employment tax — both structures get taxed the same way. Whether that wall is worth the cost depends on two things: how much you earn and what state you’re in.
What an LLC Actually Does (and Doesn’t Do)
Think of an LLC as a legal fence. On one side: the business, its contracts, its debts, its obligations. On the other side: your personal savings, your car, your home.
As a sole proprietor, that fence doesn’t exist. A legal dispute or unpaid business debt can reach straight through to personal assets. An LLC changes that — but it doesn’t change anything about how the IRS taxes the income.
The biggest surprise for first-time LLC filers: A single-member LLC is what the IRS calls a “disregarded entity.” It’s invisible for tax purposes. If the activity qualifies as a business, the income flows to Schedule C and self-employment tax applies at the same rate. The LLC is a legal structure, not a tax strategy.
If the activity is still classified as a hobby: Forming an LLC doesn’t reclassify it as a business. Hobby income in a single-member LLC still flows to Schedule 1, Line 8z as “Other Income” — not Schedule C. Expenses remain non-deductible under current TCJA rules. The §183 classification follows from the facts of the activity — profit history, how it’s run, documented profit intent — not from having a legal entity. See The Hobby Loss Rule Explained for what actually changes the classification.
Example — Same income, two different legal positions
Jordan sells custom illustrations online and nets $8,000 in a year. Here’s what the tax picture looks like either way:
Sole Proprietor Single-Member LLC Taxable income $8,000 $8,000 SE Tax (~15.3%) ~$1,130 ~$1,130 Federal income tax Same Same Total tax bill Identical Identical The numbers are the same. What changes is what happens if a client sues Jordan over a missed deadline, or a customer claims property damage from a product. As a sole proprietor, Jordan’s personal bank account is in play. As an LLC, the dispute stays on the business side of the fence — Jordan’s personal assets stay out of it.
An LLC doesn’t reduce the tax bill. It changes what’s at risk.
Three Situations Where LLC Formation Tends to Come Up
Situation 1: 1099s Start Arriving
Once a client pays $600 or more in a year, they’re supposed to send a 1099-NEC — and many do. When those forms start showing up, the paper trail is there: someone else is reporting that money as a business payment.
That’s usually the moment someone with hobby income starts thinking more seriously about how the activity is structured. Operating under an LLC is one of the things that makes an activity look more intentional and business-like — which matters if the IRS ever questions whether it’s a real business or a hobby.
Situation 2: Consistent Losses and the §183 Question
The Hobby Loss Rule (§183) comes into play for activities that can’t show a profit in 3 of 5 years — ones that risk having deductions disallowed. The IRS doesn’t just look at the numbers — it looks at how the activity is run. An LLC isn’t a magic shield here, but how the activity is set up matters. Courts and the IRS look at whether someone treated the activity seriously — and having a formal entity structure is one of the things that points toward “yes.”
The question is always: does this look like a business or a pastime? How it’s organized is part of the answer.
Situation 3: Personal Assets Are Worth Protecting
If a business deal goes sideways — a customer dispute, an unpaid invoice that turns into a lawsuit — a sole proprietor’s personal finances are on the table. For someone who owns a home, has savings, or has anything they’d rather not see dragged into a business problem, an LLC keeps that stuff on the other side of the fence.
How the Cost Math Works
The annual cost of an LLC varies dramatically by state. For most hobby earners, the real question is: does the cost of maintaining the LLC justify the liability protection at the current revenue level?
The Hypothetical: Sarah’s Art Sales in California
Sarah sells hand-painted prints online and at local art shows. Her numbers:
- Annual revenue: $4,200
- Annual expenses (canvas, paint, shipping, booth and platform fees): $2,800
- Net profit: $1,400
Sarah lives in California. She’s considering forming an LLC for liability protection.
Cost Amount CA LLC filing fee $70 (one-time) CA Franchise Tax Board minimum annual tax $800/yr Total Year 1 LLC cost $870 Sarah’s net profit is $1,400. Her LLC would cost $800 of that every year, regardless of whether she earns anything at all. CA’s $800 minimum franchise tax is owed even in a zero-revenue year.
The LLC math in California doesn’t favor formation until Sarah’s net profit is high enough that the $800 fee is a small fraction of the benefit — a threshold that looks very different in lower-cost states.
State Cost Comparison
The same LLC that costs $800/year in California costs $10/year in Colorado and $0/year in Wyoming or Texas.
States With High Hidden Costs
| State | Filing Fee | Annual Cost | The Catch |
|---|---|---|---|
| California | $70 | $800/yr | $800 CA Franchise Tax minimum — owed even at $0 revenue |
| New York | $200 | $9/yr | Publication requirement adds ~$200–$1,200 in required county newspaper notices |
| Massachusetts | $500 | $500/yr | High formation and renewal fees |
Lower-Cost States
| State | Filing Fee | Annual Fee | State Income Tax |
|---|---|---|---|
| Montana | $35 | $20/yr | Graduated |
| Arizona | $50 | $0/yr | Graduated |
| Colorado | $50 | $10/yr | Flat rate |
| Wyoming | $100 | $60/yr | None |
| Nevada | $425 | $350/yr | None |
Wyoming and Nevada carry no state income tax, which is relevant for higher-revenue hobby earners — though federal self-employment tax applies regardless of state.
Sole Proprietor vs. LLC: What Actually Changes
| Factor | Sole Proprietor | Single-Member LLC |
|---|---|---|
| How taxed | Schedule C | Schedule C (same — disregarded entity) |
| SE Tax rate | 15.3% | 15.3% (identical) |
| Liability protection | ❌ None | ✅ Personal assets separated |
| §183 audit signals | Weaker organizational evidence | Stronger organizational evidence |
| QBI Deduction (20%) | Available | Available |
| Home office deduction | Available | Available |
Note on the QBI deduction: The 20% Qualified Business Income deduction (§199A) shown in the table applies only to income from an IRS-recognized business — not hobby income on Schedule 1. If the activity is classified as a hobby, the QBI deduction does not apply regardless of entity structure. For activities that do qualify, the deduction is subject to income-based phase-outs and specified service trade or business (SSTB) limitations. A tax professional can confirm eligibility in your situation.
The tax bill is identical either way. The difference is what the LLC does for liability protection — and what it signals about how seriously the activity is being run.

Knowledge Check — LLC Basics
Question 1: A single-member LLC is described by the IRS as a “disregarded entity.” What does that mean in practice?
- A) The LLC pays no taxes at all
- B) The LLC’s income is taxed the same way as a sole proprietorship — on Schedule C
- C) The IRS doesn’t recognize the LLC as a legitimate business structure
Show answer
B. A “disregarded entity” means the IRS ignores the LLC’s existence for tax purposes. Income and expenses still flow through to the owner’s Schedule C, and self-employment tax applies at the same 15.3% rate as a sole proprietorship. The LLC structure provides liability protection — not a tax rate change.
Question 2: California charges an $800/year minimum franchise tax on LLCs. Under what circumstance is that tax owed?
- A) Only when the LLC earns more than $800 in profit
- B) Only in the first year of operation
- C) Every year, regardless of revenue — even in a $0 revenue year
Show answer
C. California charges $800 a year just to have the LLC on the books — it doesn’t matter if the activity earned anything that year. A slow year, a zero-revenue year, a year you barely touched the business: still $800 owed to the state.
How Self-Employment Tax Works for Both Structures
Either way — sole proprietorship or LLC — SE tax kicks in once the net profit from the activity clears $400 for the year:
- Rate: 15.3% (12.4% Social Security + 2.9% Medicare)
- Calculated on: 92.35% of net earnings
- What that looks like: $3,000 net profit → ~$424 SE tax
SE tax is separate from income tax and is often the biggest surprise for people earning self-employment income for the first time. See how SE tax interacts with hobby vs business classification for the full picture.
What LLC Formation Involves
Formation itself is straightforward — Articles of Organization are filed online in most states, an EIN comes from IRS.gov at no cost, and most states process filings within a few business days. The step that actually makes the liability protection hold is keeping the activity’s finances entirely separate from personal finances: once personal and business money are mixed, the fence the LLC creates starts to blur. The harder question isn’t how to form one — it’s whether the ongoing state fees justify the protection at the current revenue level.
