Florida IFTA Fuel Tax

IFTA Reporting And Filing Requirements In Florida

Who Needs An IFTA Registration In Florida?

Businesses based in Florida must register for an International Fuel Tax Agreement (IFTA) license if they operate qualified motor vehicles (QMVs) in two or more IFTA member jurisdictions.

A vehicle qualifies for IFTA in Florida when it is used, designed, or maintained to transport persons or property and meets any of the following criteria: 

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

Recreational vehicles, such as motorhomes, pickup trucks with campers, or buses used strictly for personal purposes, do not qualify unless they are used for business. 

Government-owned vehicles are also exempt from Florida IFTA licensing, although other IFTA jurisdictions may treat them differently.

If your Florida-based fleet operates interstate and meets the vehicle requirements above, you must complete Florida IFTA registration and maintain valid IFTA credentials for each qualified vehicle

What Are The IFTA Reporting Requirements In Florida?

Under the International Fuel Tax Agreement, Florida acts as your base jurisdiction for fuel tax reporting if your qualified motor vehicles are based in Florida, your operational records are maintained or made available in Florida, and your vehicles accrue some mileage in Florida. 

If you hold a Florida IFTA license, you must file quarterly IFTA fuel tax returns with Florida.

Instead of filing separate fuel tax returns in every state where your fleet operates, you:

• File one quarterly Florida IFTA tax return
• Report miles traveled in each jurisdiction
• Report fuel purchases by jurisdiction
• Calculate taxes owed or credits earned using current IFTA fuel tax rates 

Once your Florida IFTA return is submitted, Florida processes the return and distributes the appropriate fuel tax amounts to the jurisdictions where your vehicles operated. 

You are still required to file Florida IFTA returns even if:

• No miles were traveled during the quarter
• No fuel was purchased during the quarter
• Your fleet operated only within Florida for that quarter
• No tax is owed

Florida carriers must also keep accurate mileage, fuel, and operational records. These records may be requested during an IFTA audit.

How Do You File an IFTA Report in Florida?

You can file your Florida IFTA return using a two-step process:

1. Prepare Your IFTA Report

   Before filing, gather and organize the mileage and fuel records for all qualified motor vehicles in your fleet, including:

   • Total miles traveled in all IFTA and non-IFTA jurisdictions
   • Total miles traveled in each jurisdiction
   • Taxable miles traveled in each jurisdiction
   • Total gallons of fuel placed into qualified motor vehicles
   • Tax-paid gallons purchased in each jurisdiction
   • Mileage logs, trip reports, fuel receipts, and bulk-fuel withdrawal records
   • Separate mileage and fuel totals for each fuel type used

   Use these records to calculate your fleet’s average miles per gallon and determine the taxable gallons, tax due, or credit for each jurisdiction. Review the current IFTA tax rates for the reporting quarter before completing the return.

2. Submit Your IFTA Return

   Once your report is ready, you can:

   • File electronically through Florida’s Interstate Carrier Filing System (ICFS)
   • Complete the Florida IFTA Tax Return and Schedule 1, and submit them by mail with any required payment

   Florida encourages carriers to file online because ICFS provides faster processing, online payment options, filing confirmation, and current account information. Paper filing remains available.

What Are The IFTA License Costs And Fees In Florida?

Florida does not charge a fee for the annual IFTA license.

However, Florida IFTA decals cost $4.00 per set. Each qualified motor vehicle must have one set of two IFTA decals.

Florida IFTA decals are renewed annually, and additional decal reorders also cost $4.00 per set.

Your Florida IFTA account must remain active and in good standing to continue receiving annual IFTA license and decal renewals.

What Are The IFTA Penalties And Interest In Florida?

Florida requires carriers to file quarterly IFTA tax returns and pay all taxes due by the applicable filing deadline. 

If you fail to file your IFTA return on time or fail to pay the full amount of tax due by the deadline, Florida may assess a penalty equal to:

• $50, or
• 10% of the net tax due to all IFTA member jurisdictions

whichever amount is greater.

The $50 minimum penalty applies to all late IFTA tax returns, including returns for periods when no operations occurred or no tax is due. Florida requires an IFTA return to be filed for every quarter regardless of activity.

In addition to the penalty, interest accrues on unpaid fuel tax from the due date until the balance is paid. 

Under IFTA, the annual interest rate for U.S. jurisdictions is set at two percentage points above the IRS underpayment rate. Interest accrues monthly at 1/12 of the annual rate. For 2026, the IFTA annual interest rate is 9%, which equals 0.75% per month. which equals 0.75% per month. These rates are published by IFTA on January first of each year, and are subject to change.  

Incomplete or inadequate mileage and fuel records may also result in additional tax assessments during an IFTA audit. Carriers must maintain documentation supporting reported distance and tax-paid fuel purchases; unsupported fuel purchases may not qualify for tax-paid fuel credits.

How Do You Renew an IFTA License in Florida?

Florida IFTA licenses and decals must be renewed annually. They are valid for the calendar year from January 1 through December 31.

Before the end of the year, FLHSMV sends active IFTA licensees renewal information and a decal reorder form. This decal reorder form also serves as the application for renewing the Florida IFTA license.

To receive new decals on time, carriers should complete renewal before December 31.

Florida allows renewed decals to be displayed beginning in December. Carriers who submit renewal documents before December 31 may continue displaying the prior year’s decals during the two-month IFTA grace period through the end of February.

Florida IFTA renewal may be delayed or denied if:

• The third quarter IFTA return has not been filed
• Previous quarterly IFTA returns are missing
• Taxes, penalties, or interest remain unpaid
• Required insurance information is not current
• The IFTA license status is not active
• Required account information is incomplete
• The account has reported “No Operations” or “Florida Miles Only” for three consecutive tax quarters

You may also request additional decals during renewal if more qualified vehicles need Florida IFTA credentials.

• Quarterly IFTA returns are missing
• Taxes, penalties, or interest remain unpaid
• Your account is suspended or inactive
• Required account information is incomplete
