Wyoming vs. Delaware vs. California for a Solo LLC

Somewhere between building the product and taking your first dollar, you hit a wall that has nothing to do with code: you need a real company. A US LLC, specifically, because it's what unlocks a US bank account, a Stripe or Wise account, and the ability to invoice American customers as a legitimate business. And the moment you start researching, you drown in contradictory advice — Delaware because that's where startups incorporate, California because that's where you're operating, an LLC or maybe a C-Corp, and a dozen formation services all insisting their way is the only way.

Most of that advice is written for a company that's raising venture capital. You are not that company — you're a solo founder shipping software, maybe from outside the US entirely, and the right answers for you are simpler and cheaper than the internet suggests. Two decisions carry almost all the weight: what kind of entity, and which state. Get those right and the rest is paperwork.

Why LLC, not C-Corp

Start with the entity type, because it's where people over-think first. The two realistic options are an LLC (Limited Liability Company) and a C-Corporation. For a solo founder, the LLC wins on nearly every axis that matters early.

An LLC gives you pass-through taxation: the company itself doesn't pay corporate income tax. Profits flow straight through to you and get taxed once, on your personal return. A C-Corp, by contrast, is taxed as its own entity, and then again when it distributes money to you — the classic double-taxation problem. The LLC also strips out the corporate ceremony: no board of directors, no shareholder meetings, no minutes to keep. It's an entity built for one person to run without a lawyer on retainer.

A C-Corp is the right tool for raising money and nothing else you're doing yet. Until you're actually fundraising, it's overhead you pay for a future that may never arrive.

So when does a C-Corp make sense? Two situations. First, if you're raising venture capital — institutional investors strongly prefer (often require) a Delaware C-Corp, and forcing them into an LLC will cost you the deal. Second, once you're consistently clearing serious profit — think roughly $500k a year and up — a C-Corp's structure opens up tax-planning strategies that can outweigh the double-taxation hit. Neither describes a founder standing up their first company. Start as an LLC; you can always convert later when the need is real, rather than paying for complexity against a hypothetical.

The state decision, in three costs

Once you've settled on an LLC, the only remaining question is which state forms it. This is where the "everyone uses Delaware" reflex quietly costs people money. Here's the honest comparison across the three states people actually consider:

Wyoming is the default for a reason. Formation runs about $100, annual upkeep is roughly $60–100 — among the lowest in the country — there's no state income tax, and it supports anonymous ownership so your name isn't splashed across a public registry. For a solo software business with no physical footprint, it checks every box without a catch.

California is the trap. If you form (or operate) in California, you owe an $800 annual franchise tax — a flat fee you pay whether the company made a million dollars or lost money all year. It is due regardless of profitability, and it applies from day one. Worse, California has been tightening its scrutiny of out-of-state LLCs that quietly do business in California without registering, so you can't always dodge it by forming elsewhere while actually operating there. Unless you genuinely need to be a California entity because that's where you physically run the business, that $800 buys you nothing a Wyoming LLC doesn't have.

Delaware is for the fundraisers. Delaware earns its reputation among startups because investors know and trust its corporate law, and its Court of Chancery is the gold standard for resolving disputes. If you have real fundraising plans, Delaware is a reasonable choice. But its formation cost is comparable to Wyoming's while its ongoing maintenance runs higher, so if you're not raising money, you're paying a premium for prestige you won't use. Choose Delaware because investors will ask for it — not by default.

For most readers of this series, the decision collapses to one line: form a Wyoming LLC unless you have a specific, present reason not to.

The registered agent you can't skip

Here's the requirement that catches everyone off guard, especially founders outside the US: every US LLC must have a registered agent — a person or service with a real, physical US street address who can receive legal documents and official state mail on the company's behalf. This is not optional and it's not a formality; the state will reject your filing without it.

Two things trip people up:

• It must be a physical address. A P.O. box does not qualify. A virtual mailbox does not qualify. The registered agent needs a genuine street address in the state of formation where a human could, in principle, be served legal papers during business hours.
• You almost certainly need to hire one. If you don't live in Wyoming (and you probably don't), you pay a registered-agent service to fill this role. Formation platforms like Northwest or Atlas bundle it in, and standalone the service runs roughly $50–150 per year. It's a small, recurring line item — budget for it as a permanent cost of keeping the company in good standing, not a one-time setup fee.

The registered agent also becomes the US address you'll lean on elsewhere. When you later apply for a bank account and the form asks for a business address, the registered agent's US address is often what raises your approval odds versus listing a foreign home address — so this one $100-a-year service quietly pulls double duty.

The through-line

None of this is complicated once you cut through advice written for a different kind of company. For a solo founder shipping software, the shape is:

• Entity: LLC. Pass-through taxation, no corporate ceremony, convertible later if you ever raise. Skip the C-Corp until fundraising or high profits make it worth the double taxation.
• State: Wyoming. ~$100 to form, ~$60–100 a year to maintain, no state income tax, anonymous ownership. Delaware only if investors demand it; California only if you truly operate there and can't avoid the $800.
• Registered agent: budgeted, physical, hired. $50–150/year for a real US street address — a P.O. box won't do, and the filing fails without one.

Getting the entity and state right is the foundation everything else in this series stacks on — the federal tax ID, the bank account, the ongoing compliance filings all assume a US LLC exists first. The good news is that the setup is cheaper and less exotic than the "incorporate in Delaware like a real startup" chorus implies. A one-person software company doesn't need a startup's legal machinery. It needs a Wyoming LLC, a registered agent, and about $200 a year to keep the lights on.
