Delaware C-Corp or LLC for My Startup?
If you plan to raise money from startup investors, form a Delaware C-corporation. That is the entity every standard financing document assumes, and since last year's tax changes it is also where the founder tax benefits live. If you are building a business you intend to own and run on its own profits, an LLC is usually the better home. The expensive version of this decision is drift: operating as an LLC "for now" while planning a raise, because converting costs time and money at exactly the moment you are short on both.

The venture path has a default
When a startup raises institutional money, the documents do most of the deciding. The Y Combinator SAFE converts into preferred stock of a corporation. The NVCA model documents that govern priced rounds assume a Delaware corporation. And most venture funds are restricted by their own investor agreements from holding LLC interests, because pass-through income creates tax headaches for their limited partners. You can spend a financing arguing with all of that, or you can form the entity the entire apparatus was built around.
Why Delaware specifically: fifty years of corporate case law, a dedicated business court, and the practical fact that every startup lawyer and every investor's counsel works from the same playbook. Familiarity is worth real money in a financing, because diligence on a standard Delaware C-corp is short, and short diligence is cheap diligence. I covered what those costs look like in How Much Does a Startup Lawyer Cost in 2026.
Then there is the tax reason, which got much bigger recently. Qualified small business stock under Section 1202 lets founders and early investors exclude gain on a sale, and for stock issued after July 4, 2025, the rules improved substantially: 50% of the gain excluded after a three-year hold, 75% after four years, 100% after five, with a per-company cap raised to $15 million and a gross-asset ceiling raised to $75 million. Only C-corporation stock qualifies. LLC interests never do, and the holding-period clock does not start until the entity is a corporation. Every month you operate as an LLC on the way to a raise is a month that clock has not started running.
When the LLC is the right answer
Plenty of good businesses should never touch a C-corp. If the plan is profitability and distributions rather than outside equity, the LLC gives you a single layer of tax, money out without dividend mechanics, and near-total flexibility in how owners split economics. Agencies, consultancies, real estate vehicles, family companies, and holding entities live happily here. Delaware charges an LLC a flat $300 a year, no annual report required, and if the business operates in one state with no fundraising plans, your home state's LLC is often the more sensible choice anyway, since a Delaware entity operating elsewhere pays for a registered agent and a second state registration without getting much back.
What Delaware actually costs (less than the debate about it)
A Delaware corporation's franchise tax has a minimum of $175 or $400 a year depending on the calculation method, plus a $50 annual report fee, due March 1. A warning you will be glad to have read: Delaware's default bill for a startup with a standard 10,000,000 authorized shares can arrive looking like tens of thousands of dollars. It is almost never right. Recalculate under the assumed par value method, which prices most early-stage companies at or near the $400 floor, and pay the corrected number. If entity choice is swinging on a few hundred dollars of annual fees, the business plan has bigger open questions than Delaware.
Converting later is routine, and still worth avoiding
Delaware allows a statutory conversion from LLC to corporation, lawyers do them constantly, and none of that makes it free. You will pay for legal and tax work during the exact weeks you are trying to close a round, investors will wait on it with varying grace, equity you promised people as an LLC has to be translated into stock and options, and the QSBS clock starts only at conversion. If a raise is anywhere in your two-year plan, form the corporation now and skip the whole exercise. The documents you will need at that first financing are covered in Three Documents That Make or Break Your Seed Round.
The bottom line
Match the entity to the capital plan, not to a blog post's default. Raising from investors, now or plausibly later: Delaware C-corp, formed early enough that the tax clock works for you. Building on your own profits: an LLC, probably in your home state. Still undecided: the C-corp keeps more doors open, and the ones it closes are cheap to reopen compared with the reverse.
FAQ
Can I start as an LLC and convert to a C-corp later?
Yes. Delaware statutory conversions are routine, and lawyers handle them all the time. You will pay for legal and tax work, usually under deal pressure, and your QSBS holding period starts only at conversion. If fundraising is realistically in your plans, forming the corporation first is cheaper than converting later.
Why do investors insist on a Delaware C-corp?
The standard financing documents (YC SAFEs, NVCA model docs) assume one, most funds' own agreements restrict them from holding LLC interests, and Delaware's settled corporate law keeps diligence short. Insisting on something else costs you negotiating capital before the terms conversation even starts.
Does an LLC qualify for QSBS?
No. Section 1202 applies only to C-corporation stock. For stock issued after July 4, 2025, the exclusion runs 50% at a three-year hold, 75% at four years, and 100% at five, capped at $15 million per company, and the clock starts when the corporation issues your stock, not when you founded the LLC.
What does a Delaware entity cost to maintain?
An LLC pays a flat $300 annual tax, due June 1. A corporation's franchise tax has a minimum of $175 or $400 depending on calculation method, plus a $50 annual report fee, due March 1. If your first franchise tax bill looks enormous, recalculate under the assumed par value method before panicking. Most early-stage startups land at or near the floor.
What about an S-corp?
An S-corp is a tax election, not a separate entity type, and venture terms end its availability fast: preferred stock and entity investors both break the election's requirements. It can make sense for profitable owner-operated businesses, which is a conversation for your accountant and lawyer together.
