Why trust this guide: structure and tax facts come from the SBA and the IRS, linked below. Costs and rules vary by state, so confirm yours. This is general education, not legal or tax advice, and we are not lawyers or accountants.
A limited liability company, or LLC, is a business structure that separates you from your business in the eyes of the law. It can protect your personal assets, such as your savings, from some business debts and claims. You do not need one to start a side hustle. In the United States, if you earn money on your own and haven't filed anything, you're generally treated as a sole proprietor by default.
So the real question isn't "Do I need an LLC?" It's "Is my side hustle risky or big enough that an LLC is worth the cost and paperwork?" Here's how to work that out.
What is the difference between a sole proprietorship and an LLC?
A sole proprietorship is the default: you and the business are the same person legally. An LLC is a separate legal entity you form with your state. The main difference is liability protection, meaning whether a business problem can reach your personal property.
Taxes are often similar. According to the IRS, a single-member LLC is generally treated as a "disregarded entity" for federal income tax unless it elects otherwise. That means you usually still report the income on your personal return, much like a sole proprietor. Our side hustle taxes guide covers the basics.
Step 1: Ask what could actually go wrong
An LLC is protection against claims. So think about risk, not status. Ask:
- Could a customer be injured or harmed by what you do (for example, physical services)?
- Do you sign contracts, lease space or hire help?
- Do you hold other people's property or money?
- Do you have significant savings or a home you'd be upset to lose?
If you sell digital templates or do freelance writing from your laptop, your risk is usually low. If you do home repair, pet care or food, it's higher. Insurance can matter more than an LLC in these cases.
Step 2: Know what an LLC doesn't do
An LLC is often oversold. Here's what it does not do:
- It doesn't lower your taxes by itself.
- It doesn't protect you from your own mistakes or negligence in every case.
- It doesn't replace insurance.
- It doesn't make your income look more "official" to customers on most platforms.
Step 3: Price the ongoing costs
Forming an LLC means a state filing fee, and many states charge annual or biennial fees on top. Some charge a minimum yearly tax. These amounts vary widely by state, so check your state's business office website before you decide. Our guide to tracking side hustle income and expenses will help you see whether the costs are worth it.
| Factor | Sole proprietor | LLC |
|---|---|---|
| Setup | None by default | State filing |
| Liability protection | None | Often yes, with limits |
| Yearly fees | None | Varies by state |
| Federal tax return | Schedule C, personal return | Usually the same, if single-member |
| Paperwork | Light | More |
Step 4: Handle the basics either way
Whether or not you form an LLC, you still need to:
- Track every dollar of income and expense.
- Set aside money for taxes, since no employer withholds them.
- Check local license and permit rules.
- Open a separate bank account.
- Consider insurance for your type of work.
The IRS notes that self-employed people generally pay self-employment tax in addition to income tax. Plan for it so April doesn't surprise you.
A worked example
Alex designs printable planners and sells them online, earning a few hundred dollars a month. The risk is low: nobody can be physically hurt by a PDF. Alex stays a sole proprietor, opens a separate checking account and tracks expenses in a spreadsheet.
A year later Alex starts offering in-person organizing in clients' homes. Now the risk is higher, since someone could claim damage to property. Alex looks at the state's LLC fees, gets a quote for liability insurance and decides to do both. The change came from risk, not from a sudden jump in income.
Common mistakes
- Forming an LLC because a video said so. Compare fees and benefits in your own state.
- Skipping the separate bank account. It makes taxes and protection harder.
- Assuming an LLC means no taxes on profit. You still owe tax on what you earn.
- Ignoring insurance. For hands-on work it may matter more.
- Forgetting state rules. Some states charge yearly fees even when you earn nothing.
Edge cases
Irregular income: Fixed annual fees hurt more when income swings. In lean months, they may take a bigger share of your profit. See how to budget on irregular income.
Tight budget: Wait. Start as a sole proprietor, build a small buffer and add protection when the numbers justify it. Our guide on whether your side hustle is worth it can help.
Starting from zero: You can begin earning today. Track income from the first dollar and decide on structure after you have a few months of data.
Platform rules: Some platforms or clients ask for a business name or tax ID. A sole proprietor can often use their own name or register a "doing business as" name.
Who should skip forming an LLC (for now)
Skip it if your hustle is low-risk, your income is small and your state charges meaningful yearly fees. Also skip it if you haven't tested whether the hustle will last. Form one when the risk, the contracts or the money at stake grow. If you're still choosing between gigs and independent work, read gig work vs. freelancing.
Quick answers
Do I need an LLC to start a side hustle? No. You can start as a sole proprietor, which is the default for individuals who earn money on their own without filing a business entity.
Does an LLC save on taxes? Not by itself. The IRS treats a single-member LLC as a disregarded entity by default, so profit is usually reported on your personal return.
What does an LLC protect? It can protect personal assets from certain business debts and claims. It doesn't cover every situation and doesn't replace insurance.
How much does an LLC cost? It depends on your state. Check your state's filing fee and any annual fees before deciding.
Can I form an LLC later? Yes. Many people start as sole proprietors and form an LLC when risk or income grows.
