Tennessee IFTA Filing Walkthrough (Quarterly)

Several of Tennessee's neighbors scatter a motor carrier across three or four portals. Tennessee does not. The Department of Revenue's Vehicle Services Division runs intrastate authority, IFTA, apportioned registration and Unified Carrier Registration, and every one of those accounts is opened, renewed and filed inside the Tennessee Taxpayer Access Point. Oversize and overweight permits are the one break in the pattern, because those belong to TDOT and run through TNTRIPS. The sourced fees and deadlines live on the Tennessee IFTA page; this walkthrough puts them in filing order.

Step 1: decide whether you license at all

Anyone based in Tennessee who operates a qualified motor vehicle in two or more member jurisdictions has to license under IFTA. What you get back is one set of credentials good in every member jurisdiction, one quarterly return covering the net tax or refund owed to all of them, and in most circumstances a single audit instead of one per state.

If Tennessee is a stop rather than a base, there is a way around licensing. A temporary fuel use permit covers freight vehicles running Tennessee highways on an occasional or infrequent basis for up to seven consecutive days. It names one vehicle, it does not travel to another truck, and it has to be in hand before you cross the state line rather than bought at the scale. Revenue does not sell it directly. Both the IFTA and IRP pages publish a roster of wire service contractors and send you to one of them, so what you actually pay is the state fee plus that contractor's charge. The sourced figure is on the Tennessee trip and fuel permits page.

One more option cuts the other way. A licensee may fold in trucks that never leave Tennessee by obtaining IFTA decals for them, which is worth doing when a mixed fleet is easier to report as one. The catch is that the decision sticks: once a vehicle is decaled it keeps getting reported until the decal expires or the vehicle leaves your authority.

Step 2: open the account on Form RV-R0011801

The application is the Application for International Fuel Tax Agreement, Form RV-R0011801, filed through TNTAP and marked new or renewal. Paper still works and mails to the Vehicle Services Division at 500 Deaderick Street in Nashville, but the online account is where the rest of the year happens. If a service or an accountant files for you, they also file the IFTA Power of Attorney, and third-party access itself is granted inside TNTAP.

Have the answers ready before you start. The form asks for the legal and trade names, the physical and mailing addresses, the IFTA account number, the USDOT number, the FEIN or Social Security number, the type of ownership, the fuel types your qualifying vehicles burn, the count of IFTA qualified vehicles, the number of decals you want, any prior IFTA licensing in another jurisdiction, and whether you keep bulk fuel storage.

Two things get an application refused. Tennessee will not issue a license while your IFTA license in another member jurisdiction is still under revocation, and it will not issue one where the application misrepresents, misstates or omits required information. Neither the Revenue IFTA page, nor the form, nor the March 2026 Motor Carrier Education Guide states a license fee or a decal fee, so this site records neither rather than inventing one.

Step 3: get the license copy and the decals into every cab

Tennessee issues one license per licensee, so the copies are your job. Make legible copies and put one in each qualified vehicle. A truck without a copy of the license is not treated as operating under the agreement at all, which is the difference between a paperwork problem and a roadside one.

Decals come as a minimum of two per qualified vehicle, one on the exterior of each side of the cab. They do not move between vehicles. When the permanent decals are on order or being affixed, an IFTA Temporary Decal Permit valid for 30 days rides in the truck in their place. Extra decals are ordered through TNTAP, again with no published price. Apportioned plates run on a separate clock at the same agency, covered on the Tennessee IRP registration page.

Step 4: settle who reports before the quarter starts

Leases decide who files, and the rule changes with the length of the lease. On a rental of 29 days or less from a lessor regularly in the business of renting vehicles without drivers, the lessor reports and pays the fuel use tax, unless the written rental contract names the lessee as the responsible party and the lessor holds a copy of the lessee's valid IFTA license for the rental term. On leases of 30 days or more with independent contractors, the two parties may designate which one reports. Where there is no written agreement, or the agreement says nothing, the lessee carries it.

Household goods carriers using independent contractors, agents or service representatives under intermittent leases follow the operating authority. The lessee is liable when the vehicle runs under the lessee's authority and the lessor is liable when it runs under the lessor's, and the base jurisdiction follows whichever party is liable.

Sort this out in writing before the quarter you have to report. The record set an auditor expects behind the return is the same in every member jurisdiction, and the national how to file IFTA guide walks it: the trip-level distance elements, the fuel receipt elements, the tighter interval a vehicle-tracking system has to write position records on, and the retention period.

Step 5: file the quarter in TNTAP

Returns are quarterly. The first quarter return is due April 30, the second July 31, the third October 31, and the fourth January 31, which is the last day of the month following the close of the reporting period. A due date landing on a Saturday, a Sunday or a legal holiday moves to the next business day. A quarter with no operations and no taxable fuel still gets a return.

Filing runs in TNTAP, with paper filers using the IFTA Tax Return and its attached instructions. The return applies each jurisdiction's current rate, and Tennessee's own diesel line this quarter is $0.2700IFTA Fuel Tax Rate Matrix, 3rd Quarter 2026 (International Fuel Tax Association, Inc. (IFTA, Inc.))Verified Jul 18, 2026 per gallon in the national matrix. Check your arithmetic in the IFTA calculator and read every jurisdiction you ran in off the IFTA rates by state table before you submit.

Credits run on their own clock. Tax-paid fuel burned outside the jurisdiction where you bought it earns full credit or refund, and a net credit above a small floor can be refunded on written request and paid within 90 days of receipt. Two conditions apply: every member jurisdiction has to be satisfied first, audit assessments included, and a credit you never claim carries forward only until it is fully offset or until eight calendar quarters have passed from the end of the quarter it accrued in.

Step 6: know what a late Tennessee return costs

Failing to file, filing late and underpaying all draw the same penalty, a flat minimum or a share of the delinquent tax, whichever is greater. The commissioner may waive it for reasonable cause. The sourced figure renders on the Tennessee IFTA page.

Interest is where a single missed quarter spreads. Tennessee assesses it on all delinquent taxes owed to each jurisdiction, calculated separately for each one from the date the tax was due, at the rate the IFTA Articles of Agreement set for a fleet based in a United States jurisdiction. A fleet based in a Canadian jurisdiction pays the Canadian federal treasury bill rate plus two percent, adjusted every calendar quarter. The part that catches people is the rounding: any part of a month the tax stays unpaid accrues a full month of interest, so paying on the second of the month costs the same as paying on the thirtieth.

Getting a revoked license back carries the one IFTA fee Tennessee publishes, payable through TNTAP and rendered on the state page. Revenue may also require a bond after late filing, late payment, or an audit the commissioner judges serious enough to protect the other member jurisdictions.

Step 7: renew in the grace window, and stay off the dormancy list

The license period is the calendar year, January 1 through December 31. Renewing carriers get a two-month grace period, January and February, to display the new credentials. During it you have to show either a valid current or prior year IFTA license and decals from the jurisdiction you are operating from, or a valid single-trip permit from the IFTA jurisdiction you are operating in. You may also run on the new credentials one month before their effective date, and doing so does not excuse the fourth quarter return for the year that just closed.

Then there is the rule that has no equivalent in most states. Tennessee may cancel or deny renewal of an IFTA license to a carrier that does not leave Tennessee and reports zero distance, or Tennessee distance only, for three or more consecutive quarters. Proof of out of jurisdiction travel may be required before that carrier can be licensed again. A fleet that licensed for one seasonal lane and then stayed home for a year fits that description without ever missing a return. If your out of state work has dried up, keep the proof of the runs you did make, because a renewal denied in January is a truck that cannot cross a state line in February.

Intrastate operating authority is a separate credential in the same portal, and a vehicle already filed under Unified Carrier Registration does not have to file for it. The Tennessee intrastate authority page carries that side of the account.

FAQ

Where do Tennessee carriers file IFTA?

In the Tennessee Taxpayer Access Point. The Department of Revenue's Vehicle Services Division opens, renews and files the IFTA account there, and the same login carries intrastate authority, apportioned registration and Unified Carrier Registration. Oversize and overweight permits are the exception, because those belong to TDOT and run through TNTRIPS.

Can Tennessee refuse to renew an IFTA license that is current on its returns?

Yes. Tennessee may cancel or deny renewal for a licensee that does not leave the state and reports zero distance, or Tennessee distance only, for three or more consecutive quarters. Proof of travel outside the jurisdiction may be required before that carrier can be licensed again.

What does Tennessee charge for an IFTA license?

Nothing that Tennessee publishes. Neither the Department of Revenue IFTA page, nor Form RV-R0011801, nor the March 2026 Motor Carrier Education Guide states a license fee or a decal fee. The one IFTA amount the state does publish is the reinstatement charge for a revoked license, and that figure renders on the Tennessee IFTA page.
