A No-BS Guide for Founders
Sole prop? LLC? S-Corp? C-Corp? Partnership? Unless you’re an attorney, the options feel overwhelming, especially when everyone online has a strong opinion and none of them are running your business.
Here’s the thing: there’s no universally “best” answer. But there is a right answer for your situation, and once you understand how each structure works, it becomes pretty obvious where you should land.
Let’s break them all down.
The Big Picture First
Every business structure answers three core questions:
- Taxes, how does the IRS see your business income, and how does that affect what you pay?
- Complexity, how much admin, paperwork, and cost does this add to your life?
- Liability, if something goes wrong (lawsuit, debt, etc.), is your personal stuff at risk?
The more protection and tax flexibility you want, the more complexity you take on. Simple as that.
Sole Proprietorship
The default. The path of least resistance.
If you’re freelancing, consulting, doing side work, or just getting started, and you haven’t formally set anything up, congratulations, you’re already a sole proprietor.
How it works:
- Zero setup. You and your business are legally the same entity.
- All income goes straight to your personal tax return (Schedule C).
- You pay self-employment tax (15.3%) on all net profit, plus income tax on top of that.
The good: Dead simple. No filings, no fees (usually), no ongoing compliance.
The bad: No liability protection. If your business gets sued, your personal bank account, car, and house are all fair game. That’s the real killer here.
Best for: Very early stage, low-risk work, testing an idea, or side income where you genuinely haven’t committed yet. Once there’s meaningful money or risk involved, it’s time to level up.
General Partnership
Like a sole prop, but with a co-founder, and shared risk.
If two or more people go into business together without forming a formal entity, you’ve got a general partnership by default.
How it works:
- Each partner reports their share of profit/loss on their personal return.
- Self-employment tax applies to each partner’s share.
- Partners are jointly and severally liable, meaning if your partner does something dumb, you can be held responsible.
The good: Still simple, no corporate-level tax, flexible profit-sharing arrangements.
The bad: The liability exposure is brutal. One partner’s mistake can sink both of you personally. And disputes between partners without a formal agreement get messy fast.
Best for: Honestly, most people should avoid this and go straight to an LLC if they’re building something real with a partner. A partnership agreement is table stakes if you’re in this structure.
Limited Liability Company (LLC)
The workhorse structure for most small businesses and startups.
This is where most founders land, and for good reason. An LLC gives you liability protection without a ton of overhead.
How it works:
- Your personal assets are protected from business debts and lawsuits (as long as you’re not mixing personal/business finances).
- By default, a single-member LLC is taxed like a sole prop; a multi-member LLC like a partnership. All profit passes through to your personal return.
- You pay self-employment tax (15.3%) on all net profit.
- No required salary, just take draws as you need.
The good: Liability protection + pass-through taxes + relatively simple compliance. Flexible ownership structure. Works in almost every state.
The bad: That self-employment tax on all profit stings as you scale. And while it’s simpler than a corporation, there are still annual fees and state filings to keep up with.
Best for: Most small businesses, freelancers who want protection, early-stage startups, real estate investors, basically anyone who wants a real business structure without a ton of overhead.
One important note: An LLC is a legal structure, not a tax structure. You can change how your LLC is taxed without changing the legal entity, which is where S-Corp election comes in.
S-Corp (LLC or Corporation with S-Corp Tax Election)
The tax optimization play for profitable small businesses.
An S-Corp isn’t a separate legal structure, it’s a tax election. An LLC (or a C-Corp) can elect to be taxed as an S-Corp by filing IRS Form 2553. Legally, you’re still an LLC. The IRS just treats you differently.
How it works:
- You must pay yourself a “reasonable salary” for the work you do (W-2, with payroll taxes).
- Remaining profits are paid out as distributions.
- Distributions are not subject to self-employment tax, only income tax.
- Everything still passes through to your personal return. No corporate tax.
The win: You’re only paying the 15.3% payroll/SE tax on your salary, not your full profit. On $120k net profit with a $60k salary, you’re potentially saving $6,000–$9,000 per year.
The complexity: Payroll setup, Form 1120S annually, and the IRS pays close attention to “reasonable compensation.” Don’t lowball your salary, that’s exactly what they audit.
Best for: Business owners with consistent net profit above ~$60,000–$80,000 who are actively working in the business. Below that threshold, admin costs often eat the tax savings.
Real examples:
| Net Profit → | Default LLC SE Tax | S-Corp Savings (est.) | Worth It? |
| $60,000 | ~$8,500 | ~$1,000–$2,000 net | Probably not |
| $120,000 | ~$17,000 | ~$6,000–$7,000 net | Yes |
| $200,000 | ~$23,000+ | ~$10,000–$15,000+ net | Definitely |

C-Corporation
The structure built for venture-backed growth companies.
If you’re building something you plan to raise institutional capital for, take public, or issue lots of equity to employees and investors, a C-Corp (typically a Delaware C-Corp) is the standard.
How it works:
- Separate legal entity. Strong liability protection.
- Pays its own federal income tax (currently 21% flat rate).
- When profits are distributed as dividends, shareholders pay tax again, the infamous “double taxation.”
- BUT: Most high-growth startups don’t pay dividends. They reinvest. So double taxation isn’t always the practical issue it sounds like.
- Stock options, 83(b) elections, preferred shares, convertible notes, all the VC-friendly tools work cleanly here.
The good: VCs and institutional investors expect it (most won’t invest in an LLC or S-Corp). Easier to issue different classes of stock. QSBS exclusion can shelter massive capital gains for early shareholders.
The bad: More expensive to set up and maintain. Double taxation on dividends. Not ideal if you’re planning to distribute profits regularly to owners rather than reinvest.
Best for: Startups planning to raise venture capital, companies planning an IPO, businesses with complex equity needs. If you’re bootstrapping and plan to stay that way, a C-Corp probably isn’t right for you.
Decision Guide
A quick-reference flowchart for founders
Fine for early validation. Zero overhead, zero cost. Get moving.
⚠ Upgrade once the idea has real traction or money involved.
You need proper structure. Continue through the questions below.
Shields personal assets from business debts and lawsuits. The default starting point for most founders.
If there’s real money or customers involved, you almost certainly need it. A single lawsuit can reach personal assets.
The gold standard for venture-backed companies. Investors expect it; SAFEs and preferred shares are built around it.
Do it early. Converting from an LLC later is possible but expensive and painful.
More flexibility. Keep evaluating below for tax optimization.
Split income between salary and distributions — potentially saving thousands in self-employment tax.
Run the numbers with a CPA first. Payroll overhead must be weighed against the savings.
S-Corp savings usually don’t justify added complexity below this profit threshold.
Pass-through taxation, no payroll filings, minimal overhead. At lower profit levels, the tax savings from an S-Corp election rarely outweigh the hassle.
Reassess annually as profits grow.
Equity split, vesting schedules, decision-making authority, what happens if someone leaves. Every detail, in writing.
Handshake partnerships are how friendships end. Regardless of entity type.
Document ownership, IP assignment, and your operating agreement. Future investors will thank you.

What Many People Get Wrong
Rushing to S-corp too early. The savings sound great on paper. But if your profit is inconsistent or you’re below the $60k threshold, you’re paying for payroll software and a more complex tax return to save almost nothing.
Staying sole prop too long. Once you’re making real money or have any client-facing risk, the liability exposure of a sole prop is genuinely dangerous. An LLC in most states costs a few hundred dollars a year. It’s worth it.
Picking C-Corp because it sounds serious. Unless you’re raising venture capital, a C-corp adds cost and complexity without a clear benefit for most small businesses.
Ignoring state rules. Every structure has state-level nuances, filing fees, franchise taxes, recognition of S-Corp elections, etc. What works in Wyoming might not be optimal in California. Your state matters.
Bottom Line
For most founders building a real, profitable business:
- Start with an LLC. It’s the right default 80% of the time.
- Add S-Corp election when the math makes sense, typically $60k+ in consistent net profit.
- Go C-Corp only if you’re raising venture capital or have a clear reason that outweighs the complexity.
- Talk to a CPA. Seriously. A one-hour conversation with a good CPA will save you more than their fee in the first year.
Structure isn’t permanent either. You can convert, elect, or reorganize as your business evolves. The goal is to pick what’s right for where you are now, not what sounds most impressive.
