International Fuel Tax Agreement
You may hear the International Fuel Tax Agreement referred to as IFTA.
What is IFTA?
The International Fuel Tax Agreement (IFTA) is a base state fuel tax agreement. Any person based in a member jurisdiction and operating a qualified motor vehicle(s) in two or more member jurisdictions is required to license under this agreement or purchase fuel trip permits for travel in member jurisdictions.
Once the SCDMV's Motor Carrier Services receives your completed Application for International Fuel Tax Agreement Credentials (SCDMV Form IFTA-1), your IFTA license and decals will be issued. This allows you to travel in all IFTA member jurisdictions. You may find more information in the MCS Manual.
What's my base jurisdiction?
South Carolina is your base jurisdiction, if all of the following are true:
- You have qualified motor vehicles based and registered in SC.
- You maintain the operational control and records for qualified motor vehicles in SC or can make those records available in SC.
- You have qualified motor vehicles which actually travel on SC highways.
- You operate in at least one other International Fuel Tax Agreement jurisdiction.
For further assistance, you may visit or call the Motor Carrier Services office in Blythewood, Monday through Friday, 8:30 a.m. to 5 p.m. at 803-896-3870.
What's a qualified motor vehicle?
A qualified motor vehicle is one used, designed, or maintained for the transportation of persons or property, and at least one of the following is true:
- Has two axles and a gross vehicle weight (GVW) or registered gross vehicle weight (GVW) of more than 26,000 pounds or 11,797 kilograms
- Has three or more axles regardless of weight
- Used in combination when the weight of such combination is more than 26,000 pounds or 11,797 kilograms GVW or registered GVW
A recreational vehicle (RV) is not a qualified vehicle. These are vehicles like a motor home, pickup truck with a trailer, or buses when used exclusively for personal pleasure. An RV may not be used in connection with any business to still be considered an RV.
Farm vehicles, special mobile equipment, and buses are subject to International Fuel Tax Agreement licensing requirements if they meet the GVW or axle criteria and cross state lines.
Motor Carrier Services (MCS) emails a notification reminder when it is time to renew your International Fuel Tax Agreement (IFTA) License/Decal and file IFTA quarterly tax returns. To update your file and ensure proper notification concerning your IFTA License/Decal renewals and IFTA quarterly tax returns, you must provide MCS with an updated email address.
IFTA Web Transactions
You may register to become an online user by completing the Motor Carrier Web Entry Access Application (SCDMV Form MC-26).
The International Fuel Tax Agreement (IFTA) account identification number for companies and corporations is determined by using the prefix for South Carolina, which is SC, followed by the IFTA account number and a two digit suffix of "01" to identify the fleet. Companies using the same IFTA account number for more than one fleet will increase the suffix one number for each fleet.
The SCDMV may require an International Fuel Tax Agreement licensee to post a bond when a licensee has failed to file timely reports, when tax has not been remitted, or when an audit indicates problems severe enough that, in the department’s discretion, a bond is required to protect the interest of all member jurisdictions.
