LLC vs S-Corp vs C-Corp: Picking a Structure Without the Jargon

Most first-time founders treat the business structure question like a box to check. Just pick LLC, move on, start building. And for a lot of people that works out fine. But the structure you choose shapes how you pay taxes, how you raise money, and what happens if things go sideways. Getting it wrong doesn't usually kill a company, but it can cost you real money to fix later.

Here's the honest version: most early-stage founders should just form an LLC. If you're building a venture-backed software company, you probably want a Delaware C-Corp. If you're a profitable small business looking to reduce self-employment taxes, an S-Corp election might save you thousands per year. Everything else is mostly noise.

But let's actually walk through what these structures are, because the jargon gets in the way of making a decent decision.

LLC stands for Limited Liability Company. It's a state-level legal structure that separates your personal assets from your business debts. So if your company gets sued or can't pay its bills, creditors generally can't come after your house, your car, or your savings. That protection alone is worth forming one.

By default, a single-member LLC is taxed as a sole proprietorship, meaning all income flows through to your personal tax return. A multi-member LLC is taxed as a partnership. In both cases, you'll owe self-employment tax (currently 15.3% on the first $160,200 of net income for 2023) on top of income tax. That's the main downside people don't think about upfront.

Who should form an LLC:

• Solo founders and small teams who aren't planning to raise venture capital
• Consultants, freelancers, and service businesses going legit
• Anyone who wants liability protection without a ton of corporate overhead
• Early-stage startups who just want to get moving and can convert later

What an LLC won't do: you can't issue traditional stock to investors or employees. Venture funds generally don't invest in LLCs. If you're building something you plan to scale with outside capital, an LLC is often just a stepping stone.

A C-Corporation is what most people picture when they say "corporation." It's a separate legal entity, owned by shareholders, taxed at the corporate level. That second tax point sounds bad until you realize why investors love this structure.

VC funds, for legal and compliance reasons, almost exclusively invest in Delaware C-Corps. Delaware has business-friendly laws, a well-established body of case law, and courts that know how to handle corporate disputes. This is why you see every YC company incorporate in Delaware even if they're headquartered in Austin or New York.

The big advantages of a C-Corp:

Equity is clean. You can issue preferred and common shares, options, warrants, SAFEs. The mechanics investors expect all work smoothly.

Qualified Small Business Stock (QSBS). Under Section 1202 of the tax code, early investors and employees may be able to exclude up to $10 million in gains from federal taxes if the company qualifies. This is genuinely huge and is one of the underappreciated reasons to be a C-Corp from day one if you're planning to raise.

Retained earnings. Unlike pass-through structures, a C-Corp can keep profits inside the company without distributing them. That flexibility matters when you're reinvesting everything in growth.

The downside is double taxation in theory: the company pays corporate tax on profits, and shareholders pay capital gains or dividend taxes when they receive money. In practice, early-stage startups are usually burning cash or reinvesting everything, so double taxation isn't the real concern for most founders. It matters more when the company is profitable and paying dividends, which for most startups is far down the road.

An S-Corp isn't really a separate type of business entity. It's a tax election that an LLC or corporation can make with the IRS. When you elect S-Corp status, the business income passes through to shareholders' personal tax returns, avoiding corporate-level income tax. Similar to an LLC, but with one significant twist.

With an S-Corp, you can split your income into two buckets: a reasonable salary (subject to payroll taxes) and distributions (not subject to self-employment or payroll taxes). Done correctly, this can reduce your tax bill meaningfully once your business is generating solid profit.

Simple example: If you're netting $200,000 from your LLC, you'd owe self-employment taxes on all of it. With an S-Corp election and a $100,000 reasonable salary, you'd only owe payroll taxes on the salary portion, potentially saving $10,000+ per year. The exact number depends on your state, income, and how aggressive you are with the salary split.

But S-Corps come with real constraints:

• Maximum 100 shareholders, all of whom must be U.S. citizens or residents
• Only one class of stock allowed (kills the preferred/common structure investors expect)
• Much more administrative overhead than a basic LLC

S-Corp is almost never the right move for a venture-backed startup. It's most useful for profitable small businesses where the owner is actively working in the business and wants to reduce self-employment tax. Think: established service firm, dental practice, profitable SaaS bootstrapper doing $500K+ per year.

Here's how the three structures actually compare on the dimensions that matter to founders:

LLC: Liability protection yes; default taxation is pass-through; VC fundable rarely; no stock options (units only); no QSBS eligibility; no self-employment tax savings; low admin overhead. Best for early-stage and bootstrapped founders.

S-Corp: Liability protection yes; default taxation is pass-through; not VC fundable; no stock options (one class only); no QSBS eligibility; yes to self-employment tax savings; medium admin overhead. Best for profitable small businesses with active owner-operators.

C-Corp: Liability protection yes; taxed at the corporate level; yes VC fundable; yes stock options; potentially QSBS eligible; no self-employment tax savings; medium to high admin overhead. Best for venture-backed startups planning to raise outside capital.

One thing that isn't on this list: conversion. An LLC can convert to a C-Corp, and plenty of companies do it when they're getting ready to raise a priced round. The conversion isn't trivial but it's done routinely. If you're not sure whether you'll raise, starting as an LLC and converting later is a perfectly reasonable approach.

If you're forming a C-Corp with plans to raise venture capital, incorporate in Delaware. Full stop. Not your home state, not Wyoming, not Nevada. Delaware.

Why? Delaware's Court of Chancery is a specialized business court with judges (not juries) who understand corporate law deeply. The state has centuries of case law around corporate disputes. Investors, lawyers, and acquirers all know what to expect. If something goes sideways, you'd rather have your dispute heard in Delaware than a general civil court in your home state.

If you're just forming an LLC for a local business or bootstrapped product, your home state is usually fine. You'll save money on registered agent fees and foreign qualification costs. No need to overthink it.

For LLCs, the state of formation mostly matters for taxes. Some states have higher fees or franchise taxes. California, for instance, charges a minimum $800/year franchise tax whether you make money or not. Florida and Wyoming are popular choices for low-overhead LLCs, though you'll still need to register as a foreign entity in any state where you're actually doing business.

The most common mistake: overthinking it.

You can change your structure later. Yes, there are costs and complications, but companies do it all the time. The danger of structure paralysis is letting a solvable administrative question delay actually building and selling something.

The second mistake: taking legal advice from Reddit or founder forums without context. Someone saying "form a Delaware C-Corp on day one no matter what" might be right if they're building a VC-backed startup, but that advice is terrible if you're a solo consultant or a bootstrapped product maker. Context changes everything.

The third mistake: mixing up formation and compliance. Forming the entity is step one. After that, you need to actually maintain it: separate bank accounts, minutes if required, annual reports, proper documentation of any significant decisions. A lot of founders form an entity and then treat it like it doesn't exist, which can pierce the liability protection they created in the first place.

If you can afford it, a 30-minute consultation with a startup attorney in your area is worth more than hours of online research. Many offer free or low-cost initial consultations. For basic LLC formation, services like Stripe Atlas, Clerky, or Doola can handle the paperwork quickly and affordably.

Should I form an LLC or C-Corp first if I'm not sure yet?

Start with an LLC unless you're actively planning to raise venture capital within the next 12 months. LLCs are simpler, cheaper, and you can convert when the time comes. Plenty of companies raise their first checks as LLCs and convert before closing.

How much does it cost to form each structure?

State filing fees range from about $50 to $500 depending on the state. A Delaware C-Corp through a service like Clerky or Stripe Atlas runs $500 to $2,000 in setup fees. A simple LLC in most states can be filed for $100 to $300. Ongoing costs include registered agent fees ($50 to $300/year), annual report fees, and potentially franchise taxes.

Do I need a lawyer to form my business?

Not necessarily, especially for a basic LLC. Online formation services can handle the paperwork. But for a C-Corp with co-founders, equity splits, vesting schedules, and early investors, having a lawyer draft your founding documents properly saves headaches later. The cost is usually $1,500 to $5,000 for a straightforward incorporation with standard documents.

Can a non-U.S. citizen start an LLC or C-Corp?

Yes. Non-U.S. citizens can form both LLCs and C-Corps in the U.S., though there are tax implications and some restrictions (S-Corps, for instance, require U.S. citizen or resident shareholders). Delaware C-Corps are popular with international founders for this reason.

When should I do the S-Corp election?

Most advisors suggest considering an S-Corp election once your business is consistently netting $50,000 to $80,000 or more per year in profit. Below that, the tax savings often don't outweigh the administrative burden. Talk to a CPA who works with small businesses before making this decision.
