LLC vs sole proprietor: which is right for your side hustle?

· · 9 min read

Educational information only — not legal or tax advice. Consult a CPA for your situation.

If you have a side hustle and haven't filed any paperwork, you're already a sole proprietor. That's fine for most people starting out — but at some point, an LLC starts to make sense. Here's a plain-English breakdown of the differences, the costs, and exactly when to make the switch.

⚠️ The quick answer: Sole proprietor is the default (zero paperwork, zero cost) and works fine for side hustles earning under $10,000/year with low liability risk. An LLC adds personal asset protection, address privacy, and a professional structure — and at higher income levels, can be elected to tax as an S-corp to reduce self-employment tax.

The tax reality — LLCs don't automatically save taxes

This is the most common misconception. A single-member LLC is a "disregarded entity" for federal tax purposes — meaning the IRS treats it exactly like a sole proprietor. Your income still goes on Schedule C, and you still pay self-employment tax (15.3%) on your net profit.

An LLC only reduces taxes if it elects S-corp tax treatment with the IRS (Form 2553). Under an S-corp election:

  1. You pay yourself a "reasonable salary" (subject to SE tax)
  2. Any remaining profit passes through as distributions (not subject to SE tax)

S-corp example: A freelancer makes $80,000 net profit. As a sole proprietor, SE tax applies to all $80,000 = $11,304. As an S-corp with a $45,000 salary, SE tax applies only to $45,000 = $6,358. Savings: ~$4,946 per year — minus accounting costs of $1,500–2,500 for the extra complexity. Net savings: ~$2,500–3,400/year once the numbers work out.

When S-corp makes sense: Generally when net profit exceeds $40,000–50,000/year consistently. Below that, the accounting costs and complexity often exceed the tax savings. At $20,000 net profit, stick with sole proprietor or basic LLC.

What does an LLC actually protect?

As a sole proprietor, you and your business are the same legal entity. If a client sues you, if your business owes a debt, or if something goes wrong on the job — creditors and plaintiffs can potentially come after your personal savings, car, or home.

An LLC creates a legal wall between your business and your personal life. If the business gets sued, only business assets are at risk. Your personal bank account, house, and car stay protected (as long as you maintain the LLC properly — meaning separate bank accounts, no mixing of personal and business funds).

Who needs this protection most?

Address privacy — underrated benefit

When you file for an LLC in most states, your registered agent's address appears on public state records — not yours. Without an LLC, your home address may end up on business licenses, contracts, and state records. With a registered agent service like Northwest, their address is the public-facing one.

This matters if you work from home, sell products online, or have any reason not to want your residential address appearing in a Google search of your business name.

How much does forming an LLC cost?

StateFiling feeAnnual fee
Wyoming$100$60/yr min
Delaware$90$300/yr franchise tax
Florida$125$138.75/yr
California$70$800/yr minimum franchise tax
Texas$300No annual fee for most small LLCs
New York$200$9/yr + biennial report

In addition to state fees, you'll need a registered agent — a person or service with a physical address in your state who receives legal documents on behalf of your LLC. You can be your own registered agent (using your home address) or use a service. Northwest Registered Agent charges a flat fee and uses their address — keeping yours private.

When to stay a sole proprietor

When to form an LLC


Frequently asked questions

What is a sole proprietor?

Anyone earning self-employment income without forming a business entity. No paperwork needed — you're automatically a sole proprietor the moment you earn your first dollar from a side hustle.

Do LLCs pay less tax than sole proprietors?

Not by default. An LLC taxed as a disregarded entity pays identically to a sole proprietor. Only an S-corp election (available to LLCs) can reduce SE tax — typically worth pursuing at $40,000+ net profit.

What does an LLC protect against?

Business lawsuits and debts — they can't reach your personal assets when you have an LLC (as long as you maintain proper separation of business and personal finances).

How much does it cost to form an LLC?

$50–500 in state filing fees depending on the state, plus a registered agent (~$100–300/year). Many formation services include the first year of registered agent service.

Should I form an LLC for my side hustle?

Consider it once you're earning $10,000+/year, have personal assets to protect, work with clients in person, or want your home address off public records. For tiny or brand-new hustles, sole proprietor is fine to start.


The bottom line

Sole proprietor is the right starting point for most side hustles — zero cost, zero paperwork, fully legitimate. An LLC becomes the right move when you're earning real money, have personal assets to protect, or want address privacy. And for high earners, the S-corp election on top of an LLC is where the real tax savings kick in.

The best time to form an LLC is usually when you've proven the hustle works and are earning consistently. Don't pay state filing fees to protect a hustle that earns $200/month — but don't wait until you're earning $50,000/year without any protection either.
