How to incorporate a startup in 2026: Delaware C-corp costs, steps, and the free option

Incorporating a startup in 2026 comes down to four decisions: what entity to form (for venture-scale companies, a Delaware C-corporation), who prepares the documents (a template service, a law firm, or an attorney-reviewed platform), what it costs (Delaware raised many of its filing fees effective August 1, 2026 — budget a few hundred dollars in state fees for a standard setup, plus provider fees from $0 to $5,000), and what happens after: the EIN, the bank account, and the compliance calendar. This guide covers all four, with every cost dated and sourced.

One thing most 2026 guides get wrong: they'll tell you there is no free way to incorporate. There is one* — Rho incorporates Delaware C-corps at no cost, with every document reviewed and approved by a licensed attorney and filed on your behalf, and you can open your business bank account the same day, before your EIN arrives.

$400 refundable deposit, fully refunded once you open a Rho account and maintain a $10,000 average checking balance for 60 days. Requires at least one US-based owner or officer and a physical US operating address. Delaware C-corps only. Facts as of August 3, 2026.

What incorporation actually costs in 2026

Delaware updated a wide range of Division of Corporations fees effective August 1, 2026 (House Bill 400) — most notably expedited-service fees, where 24-hour processing can now run up to $300 and same-day up to $500. Check corp.delaware.gov for the current schedule before you file; most formation providers pass these fees through.

For a standard venture-style Delaware C-corp (10,000,000 authorized shares), plan for three layers of cost:

First decision: C-corp or LLC?

There are five entity structures available to US founders, but for most startups the choice reduces to two.

Choose a Delaware C-corp if you plan to raise venture capital — or think you might. VC funds almost universally cannot invest in LLCs: pass-through taxation creates tax problems for their institutional LPs, LLCs can't issue the preferred stock every term sheet is built on, can't grant ISOs to employees, and don't qualify for QSBS treatment. If an investor hasn't brought this up yet, they will.

An LLC often wins for bootstrapped businesses — simpler setup, fewer compliance requirements, and profits flow straight to members without corporate-level tax. If you're certain you won't raise institutional capital, an LLC (often in your home state) is a legitimate answer, and converting later is possible — though a conversion resets your QSBS holding-period clock, which can cost real money at exit.

Sole proprietorships and general partnerships offer no liability protection and can't take investment cleanly; S-corps can't issue preferred stock, which rules out VC financing entirely. They're fine structures for other kinds of businesses — just not for startups built to scale.

Why Delaware and not your home state

Delaware's dominance isn't sentimental. The Court of Chancery — a specialized business court with judges, not juries — has produced the deepest, most predictable body of corporate case law in the country, which is exactly what your investors' lawyers are pricing in when they require it. Many funds' terms explicitly require or strongly prefer Delaware. Delaware also imposes no state corporate income tax on revenue earned outside Delaware.

You don't have to live or operate there. Delaware is purely the entity's legal home; you'll register as a foreign corporation in the state where you actually operate and pay taxes there.

The recurring cost of that choice: Delaware franchise tax (due March 1 — use the assumed-par method, which typically produces a $400–$500 bill for a standard startup rather than thousands) plus a $50 annual report fee.

When to incorporate

The practical rule: incorporate when the company needs to own something.

That means immediately if any of these apply: you're writing code or building product (IP created before incorporation belongs to the individuals who made it), you're taking any money (a SAFE needs a legal entity to receive it), you're hiring anyone including contractors, you're applying to an accelerator (most require a Delaware C-corp at funding), or you have a co-founder (unincorporated collaboration means ambiguous IP ownership and no vesting).

Earlier is also cheaper at exit: the QSBS holding-period clock starts when your stock is issued. For stock issued after July 4, 2025, founders can exclude up to $15 million (or 10x basis) in capital gains from federal tax, with partial exclusions beginning at year three — every month you wait is a month off that clock.

How to incorporate: your options

Rho (free*). Rho incorporates Delaware C-corps as part of opening your account, at no cost. Incorporation is powered by Soxton, an independent law firm — which means every formation document is reviewed and approved by a licensed attorney and filed on your behalf, not generated by a template engine. You can ask questions and request changes during the process. The flow takes about 5 minutes; roughly 80% of filings complete within 24 hours. Your SS-4 (EIN application) is filed after the Delaware certificate, the registered-agent fee is included for your first year, and your Rho business account opens in the same flow — pre-EIN, so you can bank the same day. Start at rho.co/product/incorporation.

$400 refundable deposit, fully refunded once you open a Rho account and maintain a $10,000 average checking balance for 60 days. At least one US-based owner or officer and a physical US operating address required.

Stripe Atlas ($500). The most widely used formation service globally, with documents developed with a major law firm. Strong for founders already in the Stripe ecosystem. Documents are standard software-generated templates — well-tested ones — and formation typically completes within a couple of business days. You'll open your bank account separately (Rho supports Atlas founders pre-EIN through a direct integration).

Clerky ($427–$819). Founded by former startup attorneys; produces attorney-grade template documents designed to survive VC due diligence, with strong post-incorporation paperwork (SAFEs, board consents, hiring). The $427 incorporation package includes Delaware's expedited filing fee; the $819 lifetime package adds post-incorporation legal document tooling. Banking is separate here too (Rho's Clerky integration also supports pre-EIN account opening).

A startup attorney ($1,500–$5,000+). Worth it for genuinely non-standard situations: complex co-founder structures, IP entangled with a prior employer, founder disputes, unusual equity arrangements. For a standard formation, you're paying a large premium for the same documents.

DIY / generic legal sites. Cheapest sticker price, most expensive cleanup. Generic-template formations are one of the most common Series A due-diligence problems startup attorneys see.

What happens step by step

1. Certificate of Incorporation is prepared and filed with the Delaware Division of Corporations — this legally creates the company.

2. Registered agent is appointed (every Delaware corporation must maintain one; with Rho it's included for year one).

3. EIN (SS-4) is filed with the IRS after the certificate comes back. US founders with an SSN get an EIN quickly; without a US SSN or TIN it goes by fax and takes roughly two extra weeks.

4. Governance documents are executed: bylaws, incorporator and board consents, indemnification agreements.

5. Founder stock is issued — stock purchase agreements with vesting, IP assignment (CIIAA/PIIA), and your 83(b) election, which must be filed within 30 days of stock issuance. That deadline does not move, and missing it is the single most expensive administrative mistake a founder can make.

6. Bank account and money movement. Investor funds can't commingle with personal accounts — you need a business account before the first dollar moves.

With Rho, steps 1–5 are handled for you (attorney-reviewed at every step, with the full document set: certificate, bylaws, consents, CIIAA, stock purchase agreements, 83(b)s), and step 6 happens the same day you start — not weeks later.

The day after: where most guides stop

Incorporation isn't done until the company can receive and spend money. Three things, immediately:

• File your 83(b) within 30 days. No exceptions, no extensions.

• Sign PIIAs — every founder, before any more work happens. A founder who leaves without one may own a piece of the product.

• Open the business bank account. This is the step the traditional path makes slow, because most banks' onboarding is built around an EIN you may not have yet. Rho opens accounts at incorporation, the same day, before the EIN — whether you incorporated with Rho, Stripe Atlas, or Clerky — and real humans answer support 24/7 for the questions that come at midnight before a filing deadline.

Then set up your cap table (accurately, from day one — reconciling a messy early cap table during diligence is expensive) and calendar your Delaware franchise tax.

International founders

Supported, with one honest caveat: incorporation requires at least one US-based owner or officer and a physical US operating address. Founders without a US SSN or TIN can still incorporate and open a Rho account — identity verification works with a passport — but the IRS requires the EIN application to go by fax, which adds roughly two weeks.

What incorporation does not include

No formation service — free or paid — makes these go away: Delaware franchise tax is yours every year; you'll likely need to register as a foreign corporation in your operating state; and taxes, 409A valuations, and legal advice for non-standard situations (multi-jurisdiction structures, complex IP, founder disputes) genuinely call for a lawyer. Budget for those separately, whoever forms your company.
