US C-Corp Formation — Delaware & All 50 States

Form a US C-Corp — The Structure US Investors Expect

A C-Corp is the default structure for startups that plan to raise venture capital, issue shares to co-founders and employees, and build something they may one day sell. Extreme Filer incorporates your C-Corp in Delaware or your home state and walks you through stock setup, EIN, banking and yearly compliance — 100% online, from anywhere in the world.

What is a C-Corp, exactly?

A C corporation is taxed in its own right — for growth-focused startups, that separation is a feature, not a burden.

When you incorporate, your company becomes a separate legal person: it can own assets, sign contracts, open bank accounts and issue shares — and its debts belong to the company, not you, as long as finances stay separate.

The “C” refers to the part of US tax law under which the corporation pays its own tax — unlike an LLC, which passes profits to its owners. In exchange, a C-Corp offers what an LLC cannot do cleanly: unlimited shareholders, different classes of stock, and shares issuable to investors, co-founders and employees the way the startup ecosystem expects.

There is also no ownership restriction: founders need not live in the US, hold a visa or have an SSN. International teams can own 100% — a main reason this structure, not an S-Corp, is the standard route for foreign founders raising money in the US.

Who should choose a C-Corp?

A C-Corp is not right for every business — it fits a specific kind of ambition:

You plan to raise investment

Investors fund corporations, not LLCs. If fundraising is on your roadmap — even “maybe next year” — starting as a C-Corp avoids an expensive conversion later.

You have co-founders or a team

Shares split ownership clearly, vest founder stock over time, and reserve a pool for employees — every stake recorded in the stock ledger from day one.

You are building to sell or scale

Buyers understand corporations. A clean C-Corp with proper records is far easier to diligence and acquire.

You are a non-resident founder

Foreign founders can own a US C-Corp outright and raise from US investors. We handle formation, EIN and registered agent remotely.

Honest note: if you are a freelancer, agency or e-commerce seller with no plans to raise money, an LLC is usually simpler and cheaper. We will tell you so on WhatsApp.

C-Corp vs LLC vs S-Corp — the honest comparison

Three structures, three different jobs.

C-CorpLLCS-Corp
How it is taxedCorporation pays its own tax; shareholders taxed again on dividends (“double taxation”)Pass-through by default — profits flow to ownersPass-through, with strict eligibility rules
Foreign owners?Yes — 100% foreign ownership allowedYes — 100% foreign ownership allowedNo — shareholders must be US citizens or resident individuals; no foreign or corporate shareholders
Raising venture capitalThe standard — investors expect it; preferred stock availableAwkward — most VCs will not invest in an LLCNot suitable — one class of stock only
Shares & ownershipMultiple stock classes, unlimited shareholders, employee poolsMembership interests — flexible but informalOne class of stock, limited shareholders
FormalitiesHigher — bylaws, board, minutes, stock ledger, annual filingsLow — operating agreement, annual report in most statesHigher — formalities plus payroll for owner-employees
Best forStartups raising money, teams issuing shares, build-to-sell foundersFreelancers, agencies, e-commerce, solo foundersSome US-resident-owned small businesses — not open to non-residents

About “double taxation”: early-stage startups typically reinvest profits and pay founders salary, not dividends, so its impact is often small early on. It matters more for profitable companies paying regular dividends.

Why Delaware? And when your home state is better

Most venture-backed US startups are Delaware C-Corps — but Delaware is not automatically right for everyone.

The case for Delaware

  • The Court of Chancery — a specialised business court, decided by expert judges, not juries
  • Mature corporate law — the most developed, predictable corporation statute in the US
  • Investor familiarity — investors and their lawyers know Delaware paperwork; nothing needs explaining at term-sheet stage
  • Privacy & speed — director and officer names are not listed publicly, and filings are processed efficiently

When to form in your home state instead

  • If you will physically operate in one state — office, employees, warehouse — you must register there anyway
  • Delaware plus operating elsewhere means foreign qualification — registering in both states, with fees in both
  • With no fundraising plans and purely local operations, home-state incorporation is often simpler and cheaper
  • We map this out before filing, so you never pay for two states when one would do

How C-Corp formation works — 4 simple steps

Fully remote — no state portals, stock paperwork or IRS forms for you.

1

Tell us your plan on WhatsApp

Your plans, founders, and whether you will raise investment. We confirm the C-Corp fits — or honestly recommend an LLC — free, before you pay.

2

Choose state, name & share structure

We check your name, help pick the state, and set a sensible authorized-share count — room for investors and an employee pool, no franchise-tax surprise.

3

We incorporate & set up your stock

We file the Certificate of Incorporation, arrange the registered agent, prepare bylaws and resolutions, issue founder shares, and obtain your EIN.

4

Receive your company & launch

You receive your documents digitally, plus a clear calendar: 83(b) if shares vest, bank account, and your first annual and tax deadlines.

After formation: keeping your C-Corp in good standing

A corporation has more upkeep than an LLC — none of it hard, but missing it is expensive.

Delaware annual report & franchise tax

Delaware corporations file an annual report and pay franchise tax by March 1 each year. Keep your registered agent active — a company the state cannot reach can lose good standing, which investors and banks notice.

Federal & state tax returns

Every C-Corp files a federal corporate return (Form 1120) each year, even with no profit. Clean bookkeeping keeps this routine.

Corporate housekeeping

Keep bylaws current, minute major decisions, and record every share issuance or transfer in the stock ledger — the paper trail investors’ lawyers examine.

Delaware franchise tax — the two methods, explained plainly. Delaware calculates franchise tax two ways; you pay the lower. Under the Authorized Shares Method, tax is based on how many shares you authorize — why an enormous number can mean a surprisingly large first bill. Under the Assumed Par Value Capital Method, it comes from issued shares and gross assets — often far lower for an early-stage startup. We help you pick a sensible count before your first March 1.

⚠ The 83(b) deadline cannot be extended. If founder shares vest, an 83(b) election must reach the IRS within 30 days of the share grant — no extensions, no late filing. Missing it can mean tax as shares vest, at much higher values. We flag it the moment shares are issued.

A note on QSBS: shares in some C-Corps can potentially qualify for Qualified Small Business Stock treatment — a possible exclusion on gain when qualifying shares are sold — only if several IRS conditions are met, never automatically. A CPA should confirm your case.

C-Corp formation — frequently asked questions

Can a non-resident own a US C-Corp?

Yes. There is no residency, citizenship, visa or SSN requirement to own C-Corp shares, and foreign founders can own 100% of the corporation — unlike an S-Corp, whose shareholders must be US citizens or resident individuals.

C-Corp or LLC — which is better for my startup?

Planning to raise venture capital, issue shares to co-founders and employees, or sell the company one day? A C-Corp is usually right — it is what US investors expect. A lifestyle business with no outside investors is usually better as an LLC. We recommend honestly, before you pay anything.

Why do startups incorporate in Delaware?

Delaware has a specialised business court (the Court of Chancery), well-developed corporate law, and paperwork investors already know — why most venture-backed startups incorporate there. If you operate in another state, you may need to register there too; we explain this before filing.

What is double taxation, and does it apply to my C-Corp?

A C-Corp pays corporate tax on its profits, and shareholders can be taxed again on dividends — that is double taxation. Early-stage startups usually reinvest profits and pay founders a salary instead of dividends, so the impact is often small early on. An LLC avoids it through pass-through taxation.

What is an 83(b) election and why does the deadline matter?

If founder shares vest over time (restricted stock), an 83(b) election lets the IRS tax them at their grant-date value instead of as they vest. It must be filed within 30 days of the grant — no extensions, no late filings. We flag the deadline at formation; a CPA can advise if it fits you.

How is Delaware franchise tax calculated?

Delaware offers two methods — the Authorized Shares Method and the Assumed Par Value Capital Method — and lets you pay the lower. A very large authorized-share count can mean a high bill under the first; the second, based on issued shares and gross assets, often works out far lower for startups. We help you choose a sensible structure first.

What must a C-Corp file every year?

A Delaware C-Corp files an annual report and pays franchise tax by March 1 each year, and every C-Corp files a federal return (Form 1120) even with no profit. Internally: keep bylaws current, minute meetings, record every share issuance in the stock ledger. Our compliance support covers these deadlines.

Can my C-Corp shares qualify as Qualified Small Business Stock (QSBS)?

Possibly — shares in some C-Corps can qualify for Qualified Small Business Stock treatment, which may allow an exclusion on gain when qualifying shares are sold. But conditions apply — business type, how shares were acquired, a minimum holding period — never automatic. A CPA can confirm your case.
