Yes. Tennessee accepts a federal extension for franchise and excise tax: if the IRS has accepted your Form 7004, the Department of Revenue treats your state return as automatically extended for seven months, and you do not need to file a separate state extension form.1Justia Law. Tennessee Code 67-4-2015 – Filing of Returns The one condition is payment. You still have to pay enough tax to Tennessee by the original due date, because the extension covers filing only.
How the Automatic Recognition Works
Under Tennessee Code ยง 67-4-2015, a valid federal extension is the basis for additional time to file the state franchise and excise return.1Justia Law. Tennessee Code 67-4-2015 – Filing of Returns2Tennessee Department of Revenue. Due Dates and Tax Rates3Legal Information Institute. Tennessee Comp. R. and Regs. 1320-06-01-.02 – Due Date The seven-month window applies regardless of entity type.
You do not actually need the federal extension to get the state one. Any business that makes a sufficient payment to Tennessee by the original due date receives the seven-month extension automatically, whether or not a Form 7004 is on file.4Tennessee Department of Revenue. FAE 173 – Application for Extension of Time to File Franchise and Excise Tax Return The federal extension is simply the easiest path for taxpayers who already have one, because it removes any need to file state Form FAE 173.
The Payment Threshold You Still Have to Meet
An extension never extends the time to pay. To avoid the delinquency penalty, you must pay the lesser of 90% of your current-year franchise and excise liability or 100% of the tax shown on your prior-year return by the original due date.1Justia Law. Tennessee Code 67-4-2015 – Filing of Returns Meet either target and the extension is valid.
If quarterly estimated payments you made during the year already cover that threshold, you owe nothing more at extension time. In that situation, you do not need to send a payment or file Form FAE 173; the extension is granted automatically.4Tennessee Department of Revenue.

Any shortfall accrues interest from the original due date, not the extended one. Tennessee’s interest rate from July 2025 through June 2026 is 11.50%.5Tennessee Department of Revenue.

If Your Federal 7004 Is Rejected
The IRS rejects Form 7004 when the entity name or tax identification number does not match its records.6Internal Revenue Service. Instructions for Form 7004 Because Tennessee’s automatic recognition depends on a valid federal extension, a rejected 7004 leaves you without state protection on that path. You have two options before the original due date: correct and refile the federal extension, or make a payment to Tennessee through TNTAP or with Form FAE 173 that meets the state’s payment threshold. Doing neither exposes you to delinquency penalties on both sides.

What a Shortfall or Missed Deadline Costs
If you file late without a valid extension, or if your extension payment falls below the 90%/100% threshold, Tennessee assesses a delinquency penalty of 5% of the unpaid tax for each month or partial month the return is late, capped at 25%.9Tennessee Department of Revenue. 5Tennessee Department of Revenue. Tax Rates and Interest Rate Interest begins on the original due date regardless of the extension, and only full payment stops it. A valid extension with a short payment prevents the 5% monthly penalty but does not touch the interest clock.
Filing the Actual Return Later
When you file the full franchise and excise return through TNTAP, the system asks whether you filed for an extension. Answer yes so the Department of Revenue matches the return to the extension payment already on file.8Tennessee Department of Revenue.

If your extension payment exceeded the final liability, the overpayment is credited to your account or refunded.
Hold on to the TNTAP confirmation number and any certified mail receipts until the return has been filed and processed. If the Department later questions whether your extension was timely, that documentation is what you will rely on.
