LLC or C-Corp? How to Choose the Right Entity for Your Startup

The Entity Decision Is More Important Than Most Founders Realize

The choice between an LLC and a C-Corp is one of the first legal decisions a founder makes. It's also one of the hardest to undo. The entity you pick shapes your tax treatment, your ability to raise capital, the equity incentives you can offer, and the compliance obligations you'll carry for the life of the company.

Most founders who come to us have already heard that Delaware C-Corp is the default for startups. That's broadly true. But the reason matters, and there are real situations where an LLC is the better choice.

The Delaware C-Corp: Why It's the Venture Standard

If you plan to raise venture capital, the answer is almost always a Delaware C-Corporation. Here's why:

Investor compatibility. Most VC funds are structured in ways that prevent or penalize investment in pass-through entities like LLCs. Pension funds, endowments, and tax-exempt investors in those funds can face Unrelated Business Taxable Income (UBTI) issues with pass-through entities. A C-Corp eliminates this problem entirely.

Multiple classes of stock. C-Corps can issue common stock to founders and employees, and preferred stock to investors with features like liquidation preferences, anti-dilution protection, and conversion rights. LLCs can replicate some of this with membership interest classes, but the structures are less standardized and less familiar to investors.

Incentive Stock Options (ISOs). ISOs are only available in a corporate structure. They allow US employees to defer tax until shares are sold and potentially qualify for long-term capital gains treatment. This is a meaningful recruiting advantage.

QSBS eligibility. Under IRC Section 1202, gains on Qualified Small Business Stock held for more than five years can be excluded from federal income tax, up to $10 million or 10x the shareholder's basis. Only state-law C-Corporations clearly qualify. The IRS treatment of LLC membership interests as "stock" for QSBS purposes remains uncertain.

Perpetual existence and free transferability. Shares in a C-Corp can be bought, sold, or transferred without affecting the company's existence. This matters for secondary sales, acquisitions, and estate planning.

When an LLC Makes More Sense

An LLC is not always the wrong choice. It's the right choice when the business doesn't fit the venture-backed model:

Service businesses and consultancies. Pass-through taxation means profits are only taxed once, at the owner's personal rate. No double taxation.

Real estate holdings. Flow-through losses can offset other income, and the flexible allocation of profits and losses among members is valuable for real estate economics.

Fund structures. LPs in venture funds and other investment vehicles typically require flow-through treatment. The fund itself is almost always an LP or LLC.

Subsidiaries of foreign companies. A single-member LLC owned by a foreign parent is treated as a disregarded entity for US tax purposes, which simplifies the tax picture for international groups.

Bootstrapped businesses. If you're not raising VC and don't need ISOs or QSBS, the simpler pass-through taxation of an LLC may be more efficient.

The Conversion Problem

The most expensive version of this decision is making the wrong one first.

We regularly see founders who incorporated as an LLC through an online platform to save money, then need to convert to a C-Corp when investors require it. The conversion involves:

• Forming a new C-Corp and merging or converting the LLC into it
• Tax consequences that depend on the LLC's assets and liabilities at the time of conversion
• Potential issues with existing contracts, bank accounts, and third-party relationships
• Reissuing equity to all members under the new corporate structure
• Legal fees that typically exceed the original incorporation cost several times over

This process can take weeks and often delays fundraising. It's avoidable.

Tax Treatment at a Glance

The fundamental tax difference is straightforward:

• C-Corp: Profits are taxed at the corporate level (currently 21% federal). When those profits are distributed as dividends, shareholders pay tax again at their individual rate. This is "double taxation."
• LLC (default): Profits and losses pass through to the members' personal tax returns. No entity-level tax. Members pay once, at their individual rate.

An LLC can also elect to be taxed as an S-Corp or even a C-Corp, which adds flexibility but also complexity.

For venture-backed startups, the double taxation concern is usually theoretical in the early years because the company is reinvesting revenue (or running at a loss). The benefits of QSBS, ISOs, and investor compatibility far outweigh the tax structure considerations.

How to Decide

The framework is simple:

1. Are you raising or planning to raise VC? Delaware C-Corp.
2. Are you building a service business, fund, or holding company? Probably an LLC.
3. Are you unsure? Start with a C-Corp. It's easier to be a C-Corp that never raises than to be an LLC that needs to convert.

We help founders make this decision before they file anything. The right entity at the start saves time, money, and headaches at every stage that follows.
