Choosing a Legal Structure for Your Startup

One of the first things you’ll do as a founder is choose a legal structure for your business. It’s not glamorous, but it matters — your entity type affects your taxes, your liability exposure, your ability to raise capital, and how much it’ll cost to change your mind later.

Here’s how the four main options stack up, and what we actually recommend depending on what you’re building.

Sole Proprietorship

A sole proprietorship is what you are by default if you start a business and don’t form a separate entity. There’s no legal separation between you and the business. Your business income goes on your personal tax return. Your business liabilities are your personal liabilities.

For a startup? Almost never the right answer. You have zero liability protection. If the business gets sued, your personal assets are on the line — your house, your savings, everything. You also can’t sell equity, which makes raising capital nearly impossible.

Sole proprietorships make sense for freelancers and solo consultants who carry professional liability insurance. For anything with real risk or growth ambitions, form a separate entity.

Partnership

A partnership is the default when two or more people start a business together. Like a sole proprietorship, a general partnership offers no liability protection for the partners. There are improved versions — limited partnerships (LPs) and limited liability partnerships (LLPs) — that provide some protection, but they’re more common in professional services (law firms, accounting firms) and real estate than in tech startups.

For startups with co-founders, an LLC or corporation is almost always the better choice. Partnerships create complicated tax situations and unclear governance. Skip them.

LLC (Limited Liability Company)

An LLC gives you liability protection (your personal assets are separate from the business) with flexible tax treatment. By default, a single-member LLC is taxed like a sole proprietorship and a multi-member LLC is taxed like a partnership — both pass-through, no corporate-level tax. You can also elect to be taxed as a corporation if that makes more sense.

LLCs are great for a lot of businesses. They’re simpler to manage than corporations, have fewer formalities, and give you flexibility in how you split profits among members.

The catch for startups: if you plan to raise venture capital, LLCs create friction. VC funds prefer (and often require) C-Corps because of preferred stock mechanics, UBTI concerns for tax-exempt investors, and standardized deal documents. Equity incentive plans (stock options) are also more complex in an LLC. You’ll likely end up converting to a C-Corp before your first institutional round anyway.

Our take: if you’re bootstrapping or very early and unsure about fundraising, an LLC is a reasonable starting point. Just know that conversion to a C-Corp is in your future if investors come knocking.

Corporation (C-Corp)

A corporation — specifically a Delaware C-Corp — is the standard structure for venture-backed startups. It’s a separate legal entity with the strongest liability protection, the ability to issue multiple classes of stock (which VCs require), and a well-established body of corporate law that investors and their lawyers already know.

The downside is complexity: corporations require a board of directors, corporate bylaws, annual meetings, stock ledgers, and other formalities. They’re also subject to double taxation (corporate income tax plus personal tax on dividends), though as we covered in our C-Corp piece, this rarely matters for early-stage startups that aren’t yet profitable.

If you’re building a company that will raise outside capital — or might — start here. The legal infrastructure of a C-Corp is what makes venture financing, equity incentive plans, and eventually an exit (acquisition or IPO) work cleanly.

What We Recommend

For most of the founders we work with, the answer is a Delaware C-Corp. Not because it’s the only option, but because it’s the one that creates the fewest problems down the road when you’re raising money, hiring with equity, or selling the company.

If you’re building a smaller, bootstrapped business with no plans to raise outside capital, an LLC or S-Corp may be the better fit — especially for tax efficiency. But get advice before you decide. This is one of the rare early decisions that’s expensive to reverse.
