Florida IFTA Registration and Reporting Requirements

The International Fuel Tax Agreement (IFTA) is a reciprocal agreement between the 48 contiguous United States and 10 Canadian provinces. In Florida, IFTA is administered by the Florida Department of Highway Safety and Motor Vehicles (FLHSMV), Bureau of Commercial Vehicle and Driver Services. This system simplifies the reporting of fuel use taxes by allowing a Florida-based motor carrier to file a single consolidated tax return with their home state rather than filing individual returns for every jurisdiction in which they travel. Under the Florida Statutes Chapter 207, any motor carrier operating a qualified motor vehicle in two or more jurisdictions must register for IFTA and display two decals on their power unit. DispatchTool helps Florida carriers simplify this process by automatically tracking mileage by state line crossings and calculating fuel consumption for each trip. Instead of manual odometer logs, the platform generates the distance data needed to populate the IFTA-100 and IFTA-101 schedules required by the FLHSMV each quarter. By maintaining accurate electronic records, fleet owners reduce the risk of audit penalties and ensure they are claiming the correct credits for fuel purchased within the Sunshine State. Motor carriers looking to automate their fuel tax record-keeping can create a DispatchTool account to start organizing their quarterly mileage data.

Qualified Motor Vehicles and Registration

To register for IFTA in Florida, a vehicle must be used, designed, or maintained for the transportation of persons or property and meet specific criteria. A qualified vehicle must have two axles and a gross vehicle weight (GVW) or registered gross vehicle weight exceeding 26,000 pounds, or have three or more axles regardless of weight. It also applies if the vehicle is used in combination when the weight of such combination exceeds 26,000 pounds. Florida charges a $4.00 fee for the initial IFTA license and two decals for each qualified motor vehicle. Carriers must apply via the FLHSMV Form 85008, providing a valid Federal Employer Identification Number (FEIN) or Social Security Number and a Florida Department of Revenue sales tax number if applicable.

Florida Fuel Tax Rates and Surcharges

Florida’s fuel tax is comprised of several components including the state tax, local option taxes, and a SCETS (Statewide Comprehensive Enhanced Transportation System) tax. As of early 2024, the Florida Department of Revenue sets the total state tax rate for diesel at $0.374 per gallon and gasoline at $0.374 per gallon, though these rates are subject to annual indexing based on the Consumer Price Index. Unlike some states, Florida does not currently apply an additional surtax on top of the base fuel tax rate, but carriers must account for the full $0.374 when calculating their tax liability or credits. These figures are critical when filling out the IFTA-101, as they determine the 'Net Tax or Credit' for miles driven on Florida highways such as I-75, I-95, and I-10.

Quarterly Filing Deadlines and Penalties

Florida law requires IFTA returns to be filed on a quarterly basis. The deadlines are strictly enforced: Q1 (Jan-Mar) is due April 30; Q2 (Apr-Jun) is due July 31; Q3 (Jul-Sep) is due October 31; and Q4 (Oct-Dec) is due January 31 of the following year. If the last day of the month falls on a weekend or legal holiday, the next business day is the deadline. Failure to file a return by the deadline results in a penalty of $50.00 or 10% of the net tax due, whichever is greater. Additionally, interest is charged on all late payments at a rate of 1% per month or fraction thereof, starting from the day the tax was due until the day it is paid in full to the FLHSMV.

Record Keeping and Audit Requirements

The FLHSMV requires carriers to maintain detailed records for at least four years from the filing date. These records must include Individual Vehicle Mileage Records (IVMR), which document the starting and ending dates of a trip, origin and destination, route of travel, and odometer readings at jurisdictional boundaries. Fuel records must include original receipts or invoices showing the number of gallons purchased, fuel type, and the location of the purchase. Retail fuel receipts must show the price per gallon and the total amount of the sale. If an audit occurs, the carrier must be able to prove that all fuel taxes were paid at the pump; otherwise, the FLHSMV may assess the tax at the full rate without credit for prior purchases.

Florida IFTA Decal Placement and Renewals

Upon successful registration or annual renewal, the FLHSMV issues two decals for each vehicle. These must be placed on the exterior of both sides of the cab; failure to display these decals can result in a roadside citation and a fine, typically ranging from $100 to $500 depending on the enforcement officer's assessment. Renewals open in October each year for the upcoming calendar year. A grace period exists through February of the new year, but this only applies to carriers who have already submitted their renewal application and are in good standing. Carriers with delinquent returns or unpaid liabilities will not receive new decals until all balances are settled with the state.

Electronic Filing via the IFTA Portals

Florida has transitioned to mandatory electronic filing for most carriers through the FLHSMV’s IFTA online system. The portal allows users to enter total miles driven in each jurisdiction and total gallons of fuel purchased. The system automatically calculates the tax due based on the current rates for all member jurisdictions. Payment can be made via Electronic Funds Transfer (EFT) or credit card. Carriers should ensure that their records match their ELD (Electronic Logging Device) data, as the FLHSMV compares mileage reported on IFTA returns with other safety and compliance data points during state audits.

Frequently asked

What is the cost of IFTA decals in Florida?

Florida charges a flat fee of $4.00 for a set of two decals per vehicle annually. There is no additional fee for the IFTA license itself when filing the initial Form 85008.

What happens if I don't file my Florida IFTA return?

Failure to file results in a $50.00 penalty or 10% of the tax due, whichever is higher, plus 1% monthly interest. The FLHSMV may also revoke your IFTA license and notify other jurisdictions, which could lead to vehicle impoundment.

Can I get a temporary IFTA permit in Florida?

Yes, if you are not registered for IFTA, you must purchase a $45.00 temporary fuel trip permit before entering Florida. This permit is valid for 10 days and covers the fuel tax requirements for that period.

How long do I need to keep my IFTA fuel receipts in Florida?

Under Florida Statute 207.005, you must maintain all fuel and mileage records for a period of four years. These must be available for inspection by the FLHSMV or the Florida Department of Revenue at any time.

Do I need IFTA for a 26,000 lb truck in Florida?

If the vehicle is exactly 26,000 lbs and has only two axles, it does not require IFTA. However, if it exceeds 26,000 lbs GVW or has three or more axles, it is a 'qualified motor vehicle' and must be registered.
