Mississippi IFTA Fuel Tax

IFTA Reporting and Filing Requirements in Mississippi

Who Needs IFTA Registration In Mississippi?

You generally need a Mississippi International Fuel Tax Agreement (IFTA) license if Mississippi is your base jurisdiction and you operate a qualified motor vehicle in Mississippi and at least one other IFTA member jurisdiction. The license allows you to report and pay fuel taxes through one quarterly return filed with the Mississippi Department of Revenue (DOR). 

A qualified motor vehicle is one used, designed, or maintained to transport people or property and meets at least one of the following criteria:

• Has two axles and a gross vehicle weight or registered gross vehicle weight exceeding 26,000 pounds
• Has three or more axles, regardless of weight
• Is used in combination when the combined gross vehicle weight or registered gross vehicle weight exceeds 26,000 pounds

Recreational vehicles used exclusively for personal purposes are not considered qualified motor vehicles.

Mississippi generally qualifies as your base jurisdiction when your qualified vehicles are registered there, your fleet’s operational control and records are maintained or available there, and your fleet travels some distance in Mississippi.

If your qualified vehicles operate only within Mississippi, you do not need an IFTA license. Carriers that make only occasional interstate trips may instead obtain the required fuel permits for the jurisdictions in which they travel.

What Are the IFTA Reporting Requirements In Mississippi?

Mississippi IFTA license holders must file a quarterly fuel tax return for every reporting period, even if no qualified vehicles operated or no tax is due. If you had no reportable activity during the quarter, you must still submit a no-activity return.

Each Mississippi IFTA return generally includes:

• Total fleet miles traveled in all jurisdictions, including non-IFTA jurisdictions
• Total and taxable miles traveled in each IFTA jurisdiction
• Total fuel placed into qualified motor vehicles, reported by fuel type
• Tax-paid gallons purchased in each jurisdiction
• Average fleet miles per gallon
• The resulting fuel tax due or credit

IFTA requires carriers to report all fuel placed into the supply tanks of qualified vehicles, whether the fuel was taxed or untaxed and whether a receipt is available. This information is used with total fleet mileage to calculate average fuel economy.

Keep complete distance and fuel records supporting each return, including trip records, vehicle distance records, fuel receipts, and bulk-fuel records when applicable. Records must be retained for four years from the return’s due date or the date it was filed, whichever is later, and must be available for audit.

Mississippi IFTA returns may be filed online through Taxpayer Access Point. TAP allows carriers to enter the information manually or upload it using an Excel spreadsheet.

NOTE: Only the current Excel spreadsheet, downloadable from the Mississippi DOR, can be submitted to TAP. Any previous Excel sheets or formats will not be accepted. Do not email your Excel template to DOR.

How Do You File an IFTA Report In Mississippi?

Mississippi IFTA license holders can file their quarterly returns online through the Mississippi Taxpayer Access Point (TAP). TAP allows you to enter the return information manually or upload it using the current Excel spreadsheet template.

1. Gather Your Records

   Before filing, gather the mileage and fuel information needed to complete and support your return, including:

   • Total fleet miles traveled in all jurisdictions, including non-IFTA jurisdictions
   • Total and taxable miles traveled in each IFTA jurisdiction
   • Total fuel placed into qualified motor vehicles, reported by fuel type
   • Tax-paid gallons purchased in each jurisdiction
   • Individual vehicle trip and distance records
   • Fuel receipts and invoices
   • Bulk-fuel purchase, inventory, and withdrawal records, if applicable

   Complete records must support the mileage and fuel figures reported on the return and be available if your account is audited.

   If you need additional details or assistance with IFTA reports, review the Mississippi IRP / IFTA Record Requirements.

2. Log In to TAP and Complete Your Return

   Sign into TAP and open the IFTA return for the appropriate reporting year and quarter. You can enter the information manually or upload it using Mississippi’s current Excel template.

   When completing the return:

   • Enter total fleet miles and total fuel by fuel type
   • Report total and taxable miles traveled in each IFTA jurisdiction
   • Enter tax-paid gallons purchased in each jurisdiction
   • Review the calculated tax due or credit
   • Submit the return and pay any balance due through TAP

   TAP also allows users to make electronic payments and review account balances and activity.

3. File Every Quarter

   Mississippi IFTA license holders must file a return for every calendar quarter, even if no qualified vehicles operated or no taxable fuel was used during the reporting period. If you had no reportable activity, submit a no-activity return by the applicable deadline.

What Are The IFTA License Costs And Fees In Mississippi?

The Mississippi Department of Revenue issues an IFTA license and two decals for each qualified motor vehicle registered under the account.

Mississippi’s current public IFTA guidance does not list a separate license or decal fee. Before applying or renewing, check the amount shown in Mississippi’s TAP or contact the Department of Revenue’s IFTA Section for the current fee, if any.

How Do You Renew an IFTA License In Mississippi?

Mississippi IFTA licenses and decals are valid for one calendar year and must be renewed annually. Submit your renewal before the current credentials expire on December 31. The January and February grace period applies only to displaying renewed credentials, not to submitting the renewal itself.

1. Review Your Account Information Before renewing, confirm that your legal business name, mailing address, contact information, and other account details are current. Also determine how many decal sets you need for the upcoming license year.
   
   Update any incorrect information as part of the renewal process or contact the Mississippi Department of Revenue IFTA Section if your account requires changes that cannot be made through TAP.

2. Ensure Your Account Is In Good Standing Before renewing your Mississippi IFTA license, make sure:
   
   
   • All required quarterly IFTA returns have been filed
   • All outstanding fuel taxes, penalties, and interest have been paid
   • Your IFTA license is not suspended, revoked, or canceled
   • Your account complies with Mississippi’s licensing requirements
   IFTA renewal credentials can be issued only when required returns have been filed and outstanding taxes, penalties, and interest have been paid.
3. Renew Your IFTA License
   Log in to the Mississippi Taxpayer Access Point (TAP) and follow the instructions provided for your IFTA account. If the renewal option is unavailable or you need assistance updating your account, contact the Mississippi Department of Revenue IFTA Section. Mississippi identifies TAP as its online system for IFTA account services and provides dedicated contact information for IFTA assistance.
   
   After the renewal is processed, Mississippi will issue a renewed IFTA license and the decal sets ordered for the upcoming year. Keep a copy or electronic image of the current license in each qualified motor vehicle and display one current decal on each side of the cab.
   
   Renewing carriers have January and February to display their new credentials, provided the renewal was filed before the end of the previous year. During this grace period, vehicles may operate with valid prior-year credentials or valid new-year credentials.
