Learn the Delaware C corp formation steps, required documents, share structure decisions, and costs to file and stay compliant from day one.
By Omer Aydin ·
Delaware C Corp formation starts with filing a Certificate of Incorporation with the Delaware Division of Corporations, appointing a registered agent, then completing bylaws, board consent, and founder stock issuance.
The two decisions that actually cost founders money come at filing: how many shares you authorize and what par value you assign. Get those right and ongoing costs stay predictable. Get them wrong and you'll open a franchise tax invoice that looks like a billing error but isn't.
Delaware C-Corp formation follows a predictable sequence: file the certificate, appoint a registered agent, then build the corporate stack that investors expect to see. You can start your Delaware C-Corp formation with Lovie to handle filing, registered agent, and compliance in one place.
Steps 1 through 3 create the legal entity. Steps 4 through 6 make it investor-ready. Both matter. A filed certificate with no bylaws or stock issuance is a shell, not a company.
Steps 1 through 3 create the legal entity: you pick a name, appoint a registered agent, and file the Certificate of Incorporation with the right share structure.
The name must include a corporate designator: "Inc.," "Corp.," "Corporation," "Incorporated," or "Co." It must also be distinguishable from names already on file with the Division of Corporations. Check the state's name search tool before you commit.
Name clearance in Delaware is just the first filter. Run a trademark search before you finalize anything. A name that clears Delaware's database can still infringe a federally registered mark, and rebranding after you've issued stock is expensive.
Just like Delaware LLCs, a C-Corp requires a registered agent with a physical Delaware street address, available during business hours. The agent receives service of process and official state notices, including the annual franchise tax invoice. That invoice is the deadline most founders discover late.
Delaware's minimum certificate requires the corporate name, registered agent name and address, authorized shares and par value, and the incorporator's signature. Startups typically file an extended certificate that adds investor-standard provisions: director liability limitation and indemnification language.
The share structure decision matters more than most founders realize. The startup convention is 10,000,000 authorized shares of common stock at $0.00001 par value. That tiny par value is not cosmetic. Delaware calculates both the filing fee and the franchise tax from your authorized share count and par value. Ten million shares at a high par value can produce an enormous filing fee and a five-figure annual tax bill. Ten million shares at $0.00001 par keeps the filing fee near the minimum and the annual franchise tax manageable under the assumed-par-value method.
File directly with the Division of Corporations or through your registered agent or formation service. Expedited options (24-hour, same-day, and faster tiers) are available at escalating fees.
Steps 4 through 6 make the company investor-ready: you adopt bylaws, issue founder stock with vesting, and get the EIN to open a bank account.
The certificate creates the company. The bylaws govern it: meetings, officer roles, share transfer restrictions, and voting procedures. The incorporator signs an initial action appointing the first board of directors. The board then adopts the bylaws and appoints officers (CEO, Secretary, CFO) by written consent.
None of this gets filed with Delaware, but every investor's diligence checklist starts here. Missing or sloppy bylaws slow closings.
The board authorizes issuing common stock to founders, typically through Restricted Stock Purchase Agreements with a four-year vesting schedule and a one-year cliff. Each founder pays the par-value purchase price for their shares.
Within 30 days of that purchase, each founder should evaluate filing an 83(b) election with the IRS. This is a hard deadline. It cannot be extended, and it cannot be corrected after the fact. The tax consequences of missing it can be significant. Get advice on this step specifically.
Also assign any pre-formation IP to the company through IP assignment agreements. Investors will check, and gaps here can hold up a financing round.
Apply for the EIN free through the IRS online portal if you have a US Social Security Number. Non-resident founders use Form SS-4 by fax. The full EIN guide covers both paths. Once you have the EIN, open the corporate bank account with the filed certificate, bylaws, board consent, and EIN confirmation.
C-Corp franchise tax, unlike the flat LLC tax, is calculated using one of two methods. The default one is a trap.
Authorized Shares Method (the default on the state's invoice): This method scales with authorized share count. A startup with ten million authorized shares can receive a default invoice in the range of tens of thousands of dollars. That is not an error. It is the result of the formula Delaware applies when you don't specify otherwise.
Assumed Par Value Capital Method: This method uses issued shares and gross assets. For a typical pre-revenue startup, the result is far lower. You are entitled to pay the lower of the two amounts, but you must actively recalculate and file using this method. The state will not do it for you.
The franchise tax is due March 1 each year, along with an annual report fee. Late payment triggers a penalty plus monthly interest. Set a calendar reminder well before the deadline. The annual report and tax are filed together, and the process is straightforward once you know the assumed-par-value calculation.
A C-Corp adds real overhead: board formalities, double taxation on distributed profits, and the franchise tax mechanics described above. That overhead makes sense when you need stock for institutional investors, employee option pools, QSBS treatment on founder gains, or a priced round.
If fundraising is clearly the path, form the C-Corp now. Conversions mid-raise stall deals and cost money. If fundraising is still hypothetical, an LLC converts to a Delaware C-Corp through a routine statutory process when the time comes. For the full comparison, including QSBS eligibility and investor expectations, see the LLC vs. C-Corp guide.
Lovie is an AI-powered company formation service for tech startups. A founder describes their business through a chat interface, and Lovie prepares and submits the formation documents to the appropriate state, assists with the IRS EIN application, and manages ongoing registered agent and compliance requirements.
For developers, Lovie integrates with your IDE so you can start Delaware C-Corp formation without switching context. Formation, registered agent, and compliance reminders (including that March 1 franchise tax deadline) are handled in one place.
The startup convention is ten million shares of common stock at a very low par value. That count gives you room for founder grants, an option pool, and early hires. The low par value keeps the filing fee near the minimum and produces a reasonable franchise tax under the assumed-par-value method. Authorizing significantly more shares or using a higher par value changes both numbers.
Yes. Delaware imposes no citizenship or residency requirement on stockholders, directors, or officers. Non-resident founders apply for the EIN via Form SS-4 by fax rather than the online portal, and can open accounts at fintech-friendly banks remotely.
The certificate filing itself, no. The post-formation stack is where mistakes become expensive: stock purchase agreements with vesting, 83(b) elections, and IP assignment agreements each carry real legal and tax consequences. The 83(b) election's 30-day deadline cannot be fixed after the fact. A startup attorney or a formation service that provides investor-standard documents earns the fee at this stage.
Authorized shares are the maximum the certificate permits the company to issue. Issued shares are what stockholders actually hold. A startup might authorize ten million shares but issue eight million to founders at formation, reserving the remainder for an option pool and future hires. The franchise tax calculation under the assumed-par-value method uses issued shares and gross assets, not the full authorized count.
If institutional fundraising is clearly your path, form the C-Corp at the start. Conversions are routine but they cost money and create friction when they happen mid-raise. If outside investment is hypothetical, an LLC keeps your tax situation simpler and converts to a Delaware C-Corp through a statutory process when you need it. The decision turns on how certain your fundraising timeline is, not on the conversion mechanics.
Delaware C-Corp formation comes down to six steps: file the Certificate of Incorporation with the right share structure, appoint a registered agent, adopt bylaws, issue founder stock with vesting, file 83(b) elections within 30 days, and get the EIN. The share structure decision at filing is what keeps both the filing fee and the annual franchise tax from becoming surprises later.
Confirm your name is available and your share structure is set correctly before you file anything. Then build the post-formation stack before you talk to investors. Those two things in order from day one prevent the most common delays at the first financing round.
