Top 10 Corporate Compliance Requirements

1. Maintain a Registered Agent at All Times

Every state requires a corporation to continuously maintain a registered agent with a physical address in the state of incorporation, available during business hours to accept legal papers and state notices. A lapsed registered agent is one of the most common causes of administrative dissolution, since it means important state notices may never reach the corporation.

2. File Your Annual Report or Franchise Tax on Time

Most states require a corporation to file a periodic report, commonly called an annual report or franchise tax report, to stay in good standing, with fees and deadlines set independently by each state. Missing this deadline typically starts with a late fee, then a grace period, and eventually administrative dissolution if it's never filed.

3. Hold the Required Annual Shareholder Meeting

Most state corporation statutes require an annual meeting of shareholders to elect directors, documented with minutes. This is a corporation-specific requirement; most state LLC statutes leave meetings and minutes largely to the operating agreement instead.

4. Keep Board and Shareholder Decisions Documented

Beyond the single required annual meeting, document major board decisions, like loans, large contracts, and officer changes, with minutes or standalone resolutions. These records are evidence the corporation is actually being governed the way its bylaws describe.

5. Maintain an Accurate Stock Ledger

Keep the stock ledger current every time shares are issued or transferred, so the corporation's own records always reflect who actually owns it. A stale stock ledger creates confusion during a sale, a financing round, or a dispute among owners.

6. Keep Corporate Finances Completely Separate

Run every transaction through the corporation's own bank account, with no personal expenses paid from it and no corporate income deposited into a personal account. Commingling funds is one of the most commonly cited factors in cases where a court pierces the corporate veil.

7. File Your Federal Corporate Tax Return on Time

A C corporation files Form 1120 by the 15th day of the 4th month after its tax year ends, April 15 for a calendar-year corporation, per the IRS. An S corporation files Form 1120-S earlier, by the 15th day of the 3rd month after year-end, March 15 for a calendar-year filer. Both can request an extension using Form 7004, which extends the filing deadline but not the deadline to pay tax owed.

8. Run Payroll Correctly for Any Owner-Employee

A shareholder-employee who performs services needs to be paid a reasonable salary through properly run payroll, with correct withholding and timely deposits. Payroll tax deposit penalties accrue separately from, and in addition to, any income tax issue, and they compound quickly if missed repeatedly.

9. Report Beneficial Ownership Information to FinCEN

Under the Corporate Transparency Act, many corporations must report beneficial ownership information to FinCEN when formed, and file an updated report within 30 days of a change in beneficial ownership or company information. Check FinCEN's current guidance for your corporation's specific reporting obligation and any applicable exemption.

10. Update the IRS When Your Responsible Party Changes

If the individual the IRS treats as your corporation's responsible party changes, file Form 8822-B within 60 days of the change, even though the EIN itself stays the same. This is easy to overlook since it's triggered by a personnel change rather than a recurring calendar deadline.

Bonus: Keep Business Licenses and Permits Current

Beyond the corporate filing itself, most businesses also hold one or more state or local business licenses, and sometimes industry-specific permits, each with its own renewal schedule separate from your state's corporate filing office. Track these alongside the ten items above rather than assuming your corporate annual report automatically covers them, since they're typically issued by a different agency entirely.

Rank These by Consequence, Not Just Deadline Order

Some items on this list, like a missed registered agent renewal, risk the corporation's legal existence; others, like a delayed internal resolution, are lower-stakes if caught within a reasonable time. When your time is limited, prioritize the state-facing filings and tax deadlines first, since those carry the most immediate, hard consequences.

Multi-State Corporations Multiply This List

If your corporation is registered as a foreign corporation in other states, each one adds its own registered agent, annual report, and franchise tax requirement on top of this list, effectively repeating items 1 and 2 for every additional state.

One Calendar Beats Several Reminders

Rather than tracking each requirement separately, often across different systems or different people's memory, put every deadline on a single compliance calendar. A missed item is far more often a tracking failure than a genuine ignorance of the requirement.

This Is Not Legal or Tax Advice

The exact requirements, deadlines, and exemptions that apply to your corporation depend on your state, your industry, and your specific structure. Talk to a business attorney and a tax professional to confirm your complete compliance picture, particularly around beneficial ownership reporting, which has changed in recent years.

Assign Clear Ownership for Each Item

In a small corporation, it's common for compliance items to quietly fall through the cracks when everyone assumes someone else is handling them. Assign a specific person, even if that's the same founder for every item, as the accountable owner for each requirement on this list, so nothing depends on an informal assumption about who's watching it.

A Formation Service Can Cover Part, Not All, of This List

A registered agent and annual report filing service, like LLC Register's $99-a-year offering, covers two of the highest-consequence items on this list, but it doesn't run your board meetings, maintain your stock ledger, or file your federal tax return. Treat it as one piece of a broader compliance system rather than a complete solution on its own.
