Franchise tax is due somewhere between March and June in most states that charge it, but the exact date depends on where your business is formed, whether you operate a corporation or an LLC, and whether you follow a calendar or fiscal year. Roughly a dozen states impose a standalone franchise tax, and each sets its own schedule. The only reliable way to confirm your date is to check the comptroller or secretary of state website for the state where you owe.
The Common Deadline Windows
Most franchise tax deadlines cluster in three months: March, May, and June. Corporations and LLCs sometimes have different due dates even inside the same state. In one widely cited example, corporate filings are due March 1 while the LLC tax payment in the same state is due June 1. Other states set mid-May deadlines for everyone.
Because the pattern is inconsistent, the entity type matters as much as the state. A corporation and an LLC formed on the same day, doing similar work, may owe on different dates. If your business is registered in more than one state, expect a separate deadline in each one. Doing business across state lines can trigger a filing obligation even without a physical office there, based on employees, sales, property, or payroll thresholds set by each state.
Fiscal Year Filers
If your business closes its books on a date other than December 31, your franchise tax deadline is often tied to your accounting cycle rather than a fixed calendar date. A common pattern is a due date on the 15th day of the fourth month after the fiscal year ends, though this is not universal. A fiscal year ending June 30, for instance, may produce a franchise tax return due in mid-October rather than in spring.
Confirm the rule in writing before assuming your fiscal-year date. Some states apply the fixed calendar deadline to every filer regardless of accounting cycle, and others let the fiscal year drive the date only for certain entity types.
First-Year Filers
Newly formed businesses sometimes get a modified schedule for their first franchise tax filing. Some states do not require a return until the first full year after formation. Others prorate the tax based on how many months the entity existed during its initial year. A few states have experimented with first-year exemptions from the minimum franchise tax for newly organized entities.
Do not assume year one is a free pass. Even when no tax is due, an informational filing may still be required, and missing it can produce the same downstream problems as skipping a payment.
Small Businesses Below the No-Tax-Due Threshold
Several states exempt small businesses from actually paying franchise tax if revenue or capital falls below a threshold. These thresholds can be generous. One large state sets its no-tax-due threshold at $2,650,000 in annualized total revenue for 2026 and 2027, so most small businesses file a zero-dollar return.
The return itself is still due on the regular deadline. Filing a zero-dollar return late carries the same forfeiture risk as filing a return with tax owed. If your state uses a no-tax-due threshold, the deadline applies to you whether or not you write a check.
Extensions
If you cannot finalize your return by the deadline, most franchise tax states allow you to request an extension. The rule that catches people: an extension gives you more time to file the paperwork, not more time to pay the tax. Estimated payment is still due on the original date.
The most common payment threshold to keep an extension valid is 90% of the current year’s tax liability or 100% of the prior year’s tax, whichever applies. Underpay by more than the allowed margin and the extension is treated as invalid, with late-filing penalties applied as if you never requested it. One state invalidates the extension when the underpayment exceeds the greater of $2,000 or 30% of the final tax, so the exact rule is not identical everywhere.
A valid extension usually pushes the filing deadline out by six months, though at least one state grants seven. Some states grant the extension automatically once you submit the estimated payment on time; others require a separate extension form. Businesses required to pay by electronic funds transfer sometimes follow a different extension schedule, with an initial extension to mid-August and a second extension available to mid-November.
What Late Filing Costs
Franchise tax penalties generally come in two forms: a penalty for filing late and interest on unpaid tax.
- Late filing penalties are often calculated as a percentage of the tax due, ranging from 5% to 25% depending on how late the return is. Some states impose a flat minimum penalty even when the tax owed is small.
- Interest on unpaid tax runs from the original due date until payment, typically at annual rates between 5% and 12%. At least one state charges 12% per year on underpaid estimated tax.
- Invalid extensions trigger both consequences at once: if the state rejects your extension for underpayment, late-filing penalties and interest apply retroactively to the original due date.
The math compounds quickly. A business that files three months late on a $5,000 tax bill can easily owe $500 to $1,000 in combined penalties and interest before touching the underlying tax. Paying on time and filing the return late is always cheaper than the reverse.
Missing the Deadline Long Enough to Lose the Entity
Persistent failure to file franchise tax returns or pay the tax leads to the most serious consequence: the state administratively dissolves or forfeits your business entity. States routinely forfeit thousands of entities each year for franchise tax non-compliance.
Forfeiture is not just a paperwork problem. While the entity is dissolved, the people running the business may be held personally liable for debts and obligations incurred during that period. The limited liability protection that LLCs and corporations provide depends on the entity being in good standing. Signing a contract or taking on debt during a forfeiture can leave you personally responsible for it.
Reinstatement is possible in most states, but it is neither instant nor cheap. The typical process requires you to file all delinquent returns, pay all back taxes with accumulated penalties and interest, request a tax clearance letter from the tax authority, and then file reinstatement paperwork with the secretary of state along with a separate filing fee. The reinstatement filing fee alone ranges from roughly $30 to $100 in most states. The larger cost is the back taxes and penalties that built up during the gap.
Most states treat reinstatement as retroactive, restoring the entity’s legal existence as if the dissolution never happened. That can eliminate personal liability for debts incurred during the lapse. Courts have carved out exceptions, though, particularly when the person running the business knew about the dissolution and kept operating anyway. Reinstatement is a safety net, not a plan. The longer an entity stays forfeited, the more expensive and legally complicated the cleanup becomes.
