LLC vs. Sole Proprietor: Which Business Structure Is Right for You?

The Question Every Side Hustle Eventually Hits

You started selling your products. Money is coming in. Tax season is approaching. And someone, probably a well-meaning friend or a random internet comment, tells you that you need an LLC or you're going to lose everything.

That's not quite true. But it's not completely wrong either.

The reality is that most small product businesses start as sole proprietorships by default, and many stay that way for years. Others form an LLC early because the protection and credibility matter for their situation. Neither choice is universally right.

Here's how to figure out which one makes sense for you, without spending $300 on a consultation just to hear "it depends."

What a Sole Proprietorship Actually Is

If you sell products and haven't filed any paperwork to form a business entity, you're already a sole proprietorship. There's no registration required at the federal level. You and your business are the same legal entity.

This means a few things:

Taxes are simple. You report business income on Schedule C of your personal tax return. No separate business tax return needed.
Setup cost is near zero. You might need a local business license ($25-75 in most cities), but there's no state filing fee.
You have full control. No operating agreements, no annual reports, no corporate formalities.
Your personal assets are exposed. If someone sues your business or you can't pay a business debt, your personal savings, car, and home could be at risk.

That last point is the big one. A sole proprietorship offers zero liability protection. Your business debts are your personal debts.

What an LLC Actually Is

An LLC (Limited Liability Company) is a separate legal entity from you. When you form an LLC, you create a legal wall between your personal finances and your business finances.

Here's what that means in practice:

Liability protection. If your business gets sued or goes into debt, your personal assets are generally protected. The key word is "generally" because this protection can be pierced if you mix personal and business finances.
Tax flexibility. By default, a single-member LLC is taxed the same as a sole proprietorship (Schedule C). But you can elect to be taxed as an S-corp later if it saves you money.
Credibility. Some wholesale buyers, retailers, and business partners take you more seriously with "LLC" after your name. It signals that you're committed to this as a real business.
Ongoing requirements. Most states require annual reports ($50-300/year depending on the state) and you need to maintain a registered agent.

The Cost Comparison

Let's talk actual numbers, because "it depends on your state" isn't helpful.

Sole Proprietorship Costs

Local business license: $0-75/year
DBA ("Doing Business As") filing if using a business name: $10-50
Total first-year cost: $10-125

LLC Costs

State filing fee: $50-500 (varies wildly by state. California charges $70 to file plus an $800/year franchise tax. Wyoming charges $100 with a $60 annual report.)
Registered agent: $0 if you act as your own, $100-300/year if you use a service
Annual report: $0-300/year depending on state
Operating agreement: Free if you write your own using a template
Total first-year cost: $50-1,600+

California is the expensive outlier. If you're in California and making less than $5,000/year from your business, the $800 franchise tax alone might not make financial sense yet.

When a Sole Proprietorship Makes Sense

A sole proprietorship is probably fine if:

You're testing an idea. You've been selling at a few markets to see if people actually buy your products. Revenue is under $5,000/year.
Your products carry low risk. You're selling digital products, prints, or items that are very unlikely to cause physical harm.
You do not have significant personal assets to protect. If you're 22 with $800 in your bank account, there's not much for a creditor to come after.
You want to keep things simple. You're a one-person operation and the administrative overhead of an LLC isn't worth it yet.

When You Should Form an LLC

An LLC starts making sense when:

You're selling products that could cause harm. Candles, skincare, food, children's items, anything that someone could claim injured them. A personal injury lawsuit against a sole proprietor goes after everything you own.
Revenue is growing. Once you're consistently making $10,000+ per year, the liability protection is worth the filing costs.
You're signing contracts. Wholesale agreements, retail partnerships, or commercial leases are easier and safer to sign as an LLC.
You want to bring on a partner. An LLC with an operating agreement clearly defines ownership, profit sharing, and what happens if someone wants out.
You have personal assets worth protecting. A house, savings, investments. The $200 annual cost of an LLC is cheap insurance compared to losing your home.

The "Piercing the Corporate Veil" Problem

Having an LLC doesn't automatically protect you. Courts can "pierce the veil" and hold you personally liable if you treat your LLC like a personal piggy bank. To maintain your protection:

Keep separate bank accounts. Never pay personal expenses from your business account or vice versa.
Use your LLC name on contracts and invoices. Sign things as "Jane Smith, Member of Smith Crafts LLC," not just "Jane Smith."
Keep basic records. Track your income, expenses, and major business decisions. You don't need elaborate corporate minutes, but you need something.
Don't undercapitalize. If your LLC has $50 in its account and you're taking on $10,000 in obligations, a court might not respect the liability protection.

How to Form an LLC (the Short Version)

You don't need a lawyer for this. Here's the process in most states:

Choose a name. Search your state's business registry to make sure it's available.
File Articles of Organization. This is a one-page form on your state's Secretary of State website. Fill in your business name, address, and registered agent.
Pay the filing fee. $50-500 depending on your state.
Write an operating agreement. Even for a single-member LLC, this document establishes how the business is run. Free templates are available from your state bar association or SCORE.
Get an EIN. Free from the IRS website (irs.gov). Takes five minutes. You need this to open a business bank account.
Open a business bank account. Bring your Articles of Organization and EIN to any bank.

The whole process takes 1-3 hours plus a few days to a few weeks for your state to process the filing.

The DBA Option

If you want to operate under a business name without forming an LLC, you can file a DBA ("Doing Business As"). This lets "Jane Smith" do business as "Sunshine Candles" without creating a separate legal entity.

A DBA gives you a business name but no liability protection. It's a cosmetic filing, not a legal shield. Cost is typically $10-50.

What About S-Corp Election?

You might have heard that forming an S-corp saves you on self-employment taxes. This is true, but only once you're making enough money. The general rule of thumb is that S-corp election starts saving you money when your net business income exceeds $40,000-50,000 per year.

Below that threshold, the extra payroll costs and administrative requirements of an S-corp (running payroll for yourself, filing quarterly payroll taxes, additional tax return) cost more than you'd save. Talk to an accountant when you hit that revenue level.

The Bottom Line

If you're just starting out and testing an idea with low-risk products, a sole proprietorship is fine. Don't let anyone pressure you into spending money on an LLC before you've validated that people will actually buy what you're selling.

If you're making real money, selling products that could potentially cause harm, or you have personal assets worth protecting, an LLC is worth the relatively small annual cost. Think of it as insurance for your personal finances.

And regardless of your business structure, keep your business and personal finances separate from day one. It makes taxes easier, looks more professional to customers, and protects you legally. That's the single best thing you can do for your business, LLC or not.
