Ongoing Compliance Requirements for an Indiana Corporation

The single most important recurring filing for an Indiana corporation is the Business Entity Report — and Indiana's twist is that it's due every two years, not annually. Most states demand an annual report; Indiana runs a biennial cycle, which is both less frequent and less costly over time.

When it's due

The report is due in the anniversary month of your incorporation, every second year. If you incorporated in a given month, that month marks your recurring deadline on the two-year cycle. Indiana provides a grace period after the due date, but treating the anniversary month as your real deadline is the safe habit.

What the report covers

The Business Entity Report is not a financial disclosure. You're not reporting revenue, profit, or expenses. It updates the state's record of:

• Your registered agent and registered office
• Your corporation's principal office address
• The names and addresses of your officers and directors

How to file

File online through the INBiz portal. Online filing is faster and less expensive than filing by mail. Because the state's reminders go to your registered agent, keeping the agent current is part of making sure you actually hear about the deadline.

What happens if you miss it

After the grace period, penalties accrue, and continued failure to file leads to administrative dissolution — the state formally shuts the corporation down. A dissolved corporation loses good standing and name protection and must go through reinstatement to return. Filing on time is far cheaper and simpler than recovering from dissolution.

Unlike an LLC, a corporation is expected to observe a set of internal formalities. These aren't state filings, but they're genuine obligations of running a corporation properly — and they're what protect your liability shield if it's ever challenged.

Annual meetings and written consents

Corporations are expected to hold an annual meeting of shareholders and, as needed, meetings of the board of directors. For a closely held or single-owner corporation, these can be satisfied with a written consent in lieu of a live meeting. Either way, the point is to document the decisions the corporation makes at the ownership and board level.

Minute book and records

Keep a minute book recording the actions taken at meetings or by written consent — electing directors, appointing officers, approving major transactions, ratifying decisions. Maintain a stock ledger showing who owns what. These records are the paper trail that proves the corporation is a real, separately governed entity rather than an alter ego of its owner.

Keeping bylaws current

Your bylaws govern how the corporation operates internally. As the company evolves — new officers, changed meeting practices, updated share procedures — the bylaws should be amended to match reality. Outdated bylaws that no one follows undercut the very formality they're supposed to provide.

Maintaining a valid registered agent is a continuous requirement, not a one-time formation task. It's easy to overlook because nothing dramatic happens the day an agent's address goes stale — but the exposure is real.

Keep the agent valid at all times

Your corporation must have a registered agent with a physical Indiana street address for its entire existence. If the agent moves, resigns, or you decide to switch providers, file a change with the Secretary of State promptly. An outdated registered agent leaves the corporation non-compliant even when the biennial report is current.

Why it matters between report cycles

Because the report is only biennial, two full years can pass between the filings that confirm your agent. If your agent situation changes in the middle of that window, waiting for the next report to fix it means a long stretch where legal documents could go to an address no one is watching. Handle agent changes as they happen, not at report time.

Staying in good standing with the Secretary of State is only part of compliance. A corporation also has tax and licensing obligations that run on their own schedules.

Federal and state income tax

A corporation is a separate taxpayer. By default it files a federal Form 1120 as a C-corporation; if it has elected S-corporation status, it files Form 1120-S and passes income through to shareholders. Indiana imposes state-level corporate tax obligations as well, depending on the entity's structure and activity. These filings have their own deadlines, distinct from the biennial report — don't conflate the two.

Sales tax, withholding, and other registrations

If your corporation sells taxable goods or services, you register for sales tax with the Indiana Department of Revenue. If you have employees — and officers who work in the business generally count — you'll handle payroll withholding and related filings. These are recurring obligations tied to how you operate, not to your formation.

Licenses and permits

Indiana has no single general business license, but many industries require state licensure and many localities require their own permits. These renew on their own cycles. Confirm what applies to your specific business and location, and put those renewals on your calendar alongside the biennial report.

The compliance load for an Indiana corporation is real but manageable once you know the pieces: the biennial Business Entity Report, the internal corporate formalities, a continuously valid registered agent, and your tax and license obligations. The trap most owners fall into isn't complexity — it's forgetting, especially with a report that only comes due every two years and is easy to lose track of.

Mainstay Filing helps close that gap. As your registered agent, we're the address the state's reminders reach, and we track your biennial report deadline so it doesn't slip past the grace period. We can file the report for you, keep your agent information current, and give you a single reliable point for the state-facing compliance. That leaves you to focus on the formalities that only you can handle — documenting your meetings, keeping your minute book, and running the business — with the confidence that the state deadlines aren't going to sneak up on you.
