Short answer: post-incorporation is the set of steps a new corporation completes after the state accepts its certificate of incorporation. The incorporator hands control to the board, the board adopts bylaws and appoints officers, the company issues founder stock, and founders with vesting stock file their 83(b) elections within 30 days. Then come the EIN, a bank account and the first state and federal deadlines.
Filing a certificate of incorporation creates your corporation, but on paper it still has no bylaws, no officers and no shareholders. Post-incorporation fills that gap. This guide explains what it means, why it matters and the steps a new US corporation, such as a Delaware C-corp, should complete in its first weeks.
What is Post-Incorporation?
Post-incorporation, sometimes called organizing the corporation, covers the internal actions that make a newly filed corporation work. In Delaware, the law expects an organization meeting after the certificate is filed: the incorporator (or the initial directors, if the certificate names them) adopts the bylaws and elects directors, and the board then elects officers. The same decisions can be made by written consent instead of a meeting.
The result is a set of documents that show who runs the company and who owns it: bylaws, board resolutions, stock records and, where they apply, 83(b) elections.
Why is Post-Incorporation Important?
Until these steps are done, no one is formally authorized to act for the corporation, and no shares exist on record. In practice, that causes problems quickly:
Banks and investors ask for the paperwork. Opening an account or raising money usually means showing your certificate of incorporation, bylaws, board consent and a cap table.
Founder ownership isn't settled. Without a stock issuance, there is no record of who owns what, which becomes harder to fix once the company has value.
Tax deadlines can be missed. The 83(b) window is only 30 days and can't be extended.
If you formed an LLC rather than a corporation, the process is different: an LLC has an operating agreement instead of bylaws, members instead of shareholders, and no stock to issue.
Essential Steps in Post-Incorporation
1. Hand control from the incorporator to the board
The incorporator is the person or service that filed your certificate. If the certificate doesn't name the initial directors, the incorporator elects them, usually by a short written consent, and then steps aside. From that point, the board of directors runs the company.
2. Adopt bylaws and approve the first board resolutions
The board's first action, at a meeting or by unanimous written consent, typically covers:
Adopting the bylaws, the internal rules for meetings, voting and officer roles
Appointing officers, such as a president or CEO, a secretary and a treasurer
Approving the issuance of founder stock
Setting the fiscal year
Authorizing the company to apply for an EIN and open a bank account
Ratifying actions taken by the incorporator
Keep signed copies with your certificate of incorporation. These are the documents banks and investors will ask for.
3. Issue founder stock and record it
Founders receive their shares under a stock purchase agreement and pay for them, usually a small amount based on the par value. If the shares vest over time, the vesting terms belong in that agreement. Record every issuance in the company's stock ledger and cap table.
In Delaware, the number of authorized shares also affects your annual franchise tax. Our Delaware franchise tax calculator shows how the two calculation methods compare.
4. File 83(b) elections within 30 days
If a founder's stock is subject to vesting, an 83(b) election lets them be taxed on its value at issuance rather than as it vests. The IRS deadline is 30 days after the shares are transferred, with no extensions. The election is mailed to the IRS on Form 15620 or an equivalent statement, and a copy goes to the company. Non-US founders should check with a tax advisor whether an election makes sense for them. Read more about what happens if you don't file an 83(b) election.
5. Apply for an EIN
An Employer Identification Number (EIN) is your corporation's federal tax ID. You need it to file tax returns and hire employees, and banks and payment platforms ask for it. Founders without an SSN or ITIN apply with Form SS-4 by fax or mail. Our EIN guide walks through the application.
6. Open a business bank account
Keeping company money in an account in the corporation's name protects the separation between you and the company. Banks typically ask for the certificate of incorporation, the board resolution authorizing the account and your ID. With Clemta, you can open the account before your EIN is issued. See our guide to opening a US business bank account as a non-resident.
7. Put the first deadlines in a calendar
Obligation

Frequently Asked Questions
Do I have to hold a first board meeting?
Not in person. In Delaware, the incorporator and the board can take these first actions by written consent instead of a meeting, which is common for small corporations.
Is post-incorporation required for an LLC?
Not in the same form. An LLC has no bylaws, board or stock. Its main internal document is the operating agreement.
What happens if I skip post-incorporation?
The corporation still exists, but it has no adopted bylaws, appointed officers or issued stock on record. Banks and investors will ask for these documents, and fixing them later, especially missed 83(b) elections, is harder or impossible.
