To form a corporation in Indiana, you file Articles of Incorporation with the Indiana Secretary of State on State Form 4159, and the document must contain four things: a compliant corporate name, the total number of authorized shares, the name and Indiana street address of a registered agent, and the name and address of each incorporator.1Indiana General Assembly. Indiana Code 23-1-21-2 – Articles of Incorporation Contents Once the Secretary of State accepts the filing, the corporation exists as its own legal entity as of the filing date.
What the Articles Must Include
Indiana law identifies exactly four mandatory pieces of information:1Indiana General Assembly. Indiana Code 23-1-21-2 – Articles of Incorporation Contents
- A corporate name that meets Indiana’s naming rules and is distinguishable from every other entity on file with the Secretary of State.
- The total number of shares the corporation is authorized to issue. This sets the ceiling on ownership interests you can distribute.
- The name of the initial registered agent and the street address of the registered office in Indiana.
- The name and address of each incorporator signing the articles. Incorporators create the entity but do not automatically become directors or officers.
Everything else is optional. The statute permits additional provisions covering matters like par value, director liability limits, and internal governance rules, but those can be added later by amendment. Most founders keep the initial filing lean and let the bylaws handle internal operations.
Naming Rules That Trip Filers Up
The corporate name must include one of the designators “Corporation,” “Incorporated,” “Company,” or “Limited,” or an abbreviation such as “Corp.,” “Inc.,” “Co.,” or “Ltd.”2Indiana General Assembly. Indiana Code 23-0.5-3-2 – Required Words or Phrases Professional corporations have an added requirement: the name must contain “Professional Service Corporation” or “Professional Corporation.” Omit the designator and the Secretary of State rejects the filing.
The name also has to be distinguishable from every other business entity of the same type already on record.3INBiz. Start a Business – Business Entity Search the INBiz database first to check availability. If you find a name you want but aren’t ready to file, Indiana lets you reserve it for 120 days through an application with the Secretary of State.
The Registered Agent Requirement
Every Indiana corporation must continuously maintain a registered agent and a registered office in the state.4Indiana State Government. What Is a Registered Agent and Why Do I Need One? The registered agent accepts legal documents on the corporation’s behalf: lawsuits, tax notices, and official correspondence. The registered office must be a physical street address in Indiana. P.O. boxes do not qualify.
You have two workable options. An officer, director, or employee of the corporation can serve as agent at no cost, but that person must be reliably available at the listed address during business hours to accept hand-delivered documents. The other option is a commercial registered agent service, which charges an annual fee in exchange for guaranteed availability. Many founders start by naming themselves and switch later as the business grows.
Optional Provisions to Decide Before Filing
Indiana corporations have perpetual duration by default, meaning the entity exists until the owners dissolve it or the state revokes its status.5Indiana General Assembly. Indiana Code 23-1-22-2 – Perpetual Duration Powers You can set an end date in the articles for a short-term project, but most filers leave the default alone.
The articles may include a statement of purpose. Indiana allows a broad general-purpose clause such as “to engage in any lawful business activity,” and that’s what most corporations use. Narrowing the purpose to one industry offers no real benefit and creates the risk that expanding later will require an amendment.
If the corporation will have more than one class of stock with different voting or dividend rights, those classes have to be described in the articles.1Indiana General Assembly. Indiana Code 23-1-21-2 – Articles of Incorporation Contents A single-class structure with one type of common stock is simpler and fits most small corporations.
How to File and What It Costs
Indiana uses State Form 4159, which covers for-profit corporations, benefit corporations, and professional corporations.6Indiana Secretary of State. Business Forms You can download it from the Secretary of State’s website or file directly through the INBiz portal.
Online Through INBiz
The INBiz portal at inbiz.in.gov is the faster route. You enter the required information through a guided interface, pay by credit or debit card, and receive immediate confirmation of receipt. Online filings are typically processed within about 24 hours. A small processing fee, capped at 2.15% of the filing fee, is added at checkout.
By Mail
Paper filings go to the Secretary of State’s office in Indianapolis with a check or money order for the filing fee. Processing takes roughly five to seven business days, not counting mail transit. Documents submitted without payment are returned.
The filing fee is approximately $90 online and $100 by paper. These amounts can change, so check the INBiz fee calculator before filing to confirm the current amount. Indiana does not offer fee waivers for incorporation filings.
What to Do After the Filing Is Accepted
Once the Secretary of State verifies the articles and processes the filing, the corporation exists as of the filing date. Read the returned filing carefully. A misspelled name or wrong share count now becomes an amendment filing later.
Hold the Organizational Meeting
Indiana law requires an organizational meeting after incorporation.7Indiana General Assembly. Indiana Code 23-1-21-5 – Organizational Meeting If the articles name initial directors, those directors hold the meeting. If not, the incorporators do. This is where the corporation adopts bylaws, elects officers, authorizes initial stock issuances, and handles startup items like opening a bank account and setting a fiscal year. Document everything in written minutes as the first entry in the corporate minute book.
Bylaws are the corporation’s internal operating manual, covering how meetings are called, what constitutes a quorum, how directors are elected and removed, and what authority officers have. Bylaws are private and are not filed with the state, but they govern day-to-day operations. If a bylaw ever conflicts with the articles, the articles control.
Get an EIN
Nearly every corporation needs a federal Employer Identification Number from the IRS. It is the business equivalent of a Social Security number and is required to open a bank account, hire employees, and file tax returns.8Internal Revenue Service. About Form SS-4, Application for Employer Identification Number (EIN) Apply online through the IRS website at no cost and receive the number immediately.
Consider an S Corporation Election
By default, the IRS taxes a corporation as a C corporation: the entity pays corporate income tax and shareholders pay again on dividends. Many small corporations elect S corporation status on IRS Form 2553 to avoid the double layer. The deadline is no more than two months and 15 days after the beginning of the tax year the election should take effect.9Internal Revenue Service. Instructions for Form 2553 Miss that window and the election waits for the following tax year unless you can show reasonable cause for a late filing.
S corporation status is not open to every corporation. The entity must have no more than 100 shareholders, only one class of stock, and all shareholders must be U.S. citizens or residents who are individuals, estates, or certain qualifying trusts. Corporations and partnerships cannot hold S corporation shares.
Keeping the Corporation in Good Standing
Biennial Business Entity Report
Indiana requires every corporation to file a Business Entity Report every two years. The first report is due two years after the formation date, in the same month the corporation was formed, and you have until the end of that month before it is late.10INBiz. Business Entity Reports The fee for a for-profit corporation is $32 online through INBiz or $50 by paper.
This is the easiest compliance task to forget and the consequences are severe. The state will administratively dissolve a corporation that fails to file, and a dissolved corporation cannot legally conduct business in Indiana.11INBiz. Administrative Dissolution/Revocation Reinstatement requires a tax clearance from the Department of Revenue, which can take four to six weeks. The corporation’s name is only protected for 120 days after dissolution, so waiting too long lets someone else register it.
Required Corporate Records
Indiana law requires every corporation to keep specific records at its principal office: the current articles and all amendments, current bylaws, minutes of shareholder meetings for the past three years, written communications to shareholders for the past three years, a list of current directors and officers, and the most recent biennial report.12Indiana General Assembly. Indiana Code 23-1-52-1 – Required Records Minutes of board meetings and records of any actions taken without a meeting must be kept as permanent records. Shareholders have a statutory right to inspect these records, so keeping them organized is not optional.
Amending the Articles
When the corporation needs to change its name, increase its authorized shares, or add a class of stock, Indiana handles the change through Articles of Amendment filed with the Secretary of State. The board of directors must first adopt a resolution proposing the amendment, and then shareholders must approve it by vote. The fee has historically been $20 for electronic filing and $30 by paper.13Indiana General Assembly. Indiana Code 23-1-18-3 – Fees Confirm the current amount on INBiz before filing. Getting the articles right the first time saves both the fee and the shareholder vote, which is worth remembering when you decide on authorized share counts and any optional provisions for the initial filing.
One boundary worth noting: as of March 2025, FinCEN exempts all entities formed in the United States from the Corporate Transparency Act’s beneficial ownership reporting requirement, so a standard Indiana corporation has no FinCEN filing obligation.14FinCEN. Beneficial Ownership Information Reporting The rule could change through future legislation or rulemaking, so it is worth checking before you assume nothing is due.
