Everyone tells you to form a Delaware C-Corp. Most of the time, they're right. But "most of the time" isn't always — and picking the wrong structure can cost you thousands in taxes or lock you out of investors down the road.
Here's a direct comparison so you can make the call based on your actual situation, not generic advice.
The Short Answer
Form a Delaware C-Corp if:
- You plan to raise venture capital
- You want to issue stock options (ISO) to employees
- You expect to be acquired or go public someday
Form an LLC if:
- You're bootstrapping and want to avoid double taxation
- You're a solo founder or small team with no VC plans
- You're building a real estate, consulting, or service business
Why VCs Require a C-Corp
Venture capital firms invest through preferred stock. LLCs don't have stock — they have membership interests. Converting an LLC to a C-Corp later is possible, but it's expensive, messy, and creates tax events that investors hate.
Most term sheets include a condition that the company must be a Delaware C-Corp before the check clears. If you're planning to raise a seed round, a Series A, or anything in between, start as a C-Corp and save yourself the conversion headache.
Delaware specifically is the default because its Court of Chancery has 200+ years of corporate case law. Investors and acquirers know exactly what they're getting. Any other state introduces uncertainty that sophisticated investors don't like.
The Double Taxation Problem
C-Corps pay federal corporate income tax (currently 21%) on profits. If those profits are then distributed to shareholders as dividends, shareholders pay personal income tax on them too. That's double taxation.
LLCs avoid this entirely. By default, an LLC's profits flow through to the owners' personal tax returns. You pay once, at your personal rate.
Here's the thing: if you're a C-Corp that reinvests all profits into the business — which most startups do — double taxation doesn't affect you in practice. You never distribute dividends, so the second layer never triggers. This is why the C-Corp tax disadvantage is mostly theoretical for high-growth startups.
Stock Options: A Major C-Corp Advantage
If you want to attract and retain talent with equity, C-Corps are significantly better. Incentive Stock Options (ISOs) are only available to C-Corp employees. ISOs have favorable tax treatment — employees pay taxes when they sell shares, not when they exercise options.
LLCs can grant "profits interests," which serve a similar purpose but are more complex to administer and less understood by employees used to traditional stock options. If you're hiring from tech companies, they'll expect ISOs.
The Delaware LLC: A Middle Ground
If you want LLC tax treatment but don't want to commit to a state with unfamiliar LLC law, Delaware LLCs are respected and well-understood. You can elect to be taxed as an S-Corp (subject to restrictions) to reduce self-employment taxes if you're paying yourself a salary.
However: S-Corp election is not available to corporations with more than 100 shareholders, non-US shareholders, or more than one class of stock. Once you bring on international investors, the S-Corp option disappears.
What Actually Matters for Your Decision
Ask yourself three questions:
- Will I raise outside capital in the next 2 years? If yes → C-Corp, Delaware.
- Do I want to hire employees and grant equity? If yes → C-Corp.
- Am I building a profitable business I plan to own long-term without VC? If yes → LLC, and talk to a CPA about S-Corp election.
The formation cost difference is minimal — both cost under $500 to form properly. Don't let the upfront cost drive this decision. Let the long-term tax and fundraising implications drive it.
How to Form Either One
Both entity types can be formed in a day. You'll need:
- C-Corp: Certificate of Incorporation, initial bylaws, organizational meeting minutes, stock certificates, and an EIN. File with the Delaware Division of Corporations.
- LLC: Articles of Organization and an Operating Agreement. File with your chosen state's Secretary of State.
Founder Kit generates all of these documents for you — tailored to your state, entity type, and whether you're a solo founder or have co-founders. It takes about 10 minutes.
The bottom line: if you're building something you want to scale, raise money for, or sell someday, form a Delaware C-Corp now. If you're building a profitable lifestyle business you want to own forever, an LLC probably serves you better. Both are legitimate — just match the structure to the business you're actually building.
