|---|---|---|
| Diesel (IFTA blended rate) | 41.0¢/gal ($0.410) | The figure for your return's diesel line as of Q4 2026 |
| Gasoline (IFTA blended rate) | 41.1¢/gal ($0.411) | A rare state where gasoline edges above diesel |
| — State motor fuel tax component | 22.0¢/gal ($0.220) | Rose from 21.5 cents on January 1, 2026 per DOR TIP 25B05-05 |
| — Local option average component | ≈19¢/gal | Ninth-cent, local option and pollutants taxes averaged across counties |
Florida runs on trucking: port drayage in Miami, Jacksonville and Tampa, produce out of the south, building materials down I-75 and I-95, and a tourism economy that never stops consuming. Its fuel taxes stack a state excise with pollutant fees and county local option taxes, which pushes the blended IFTA rate above every neighbor. The figures below are from the official IFTA Inc. fourth quarter 2026 tax rate matrix and the Florida Department of Revenue fuel tax page — as of Q4 2026 — always confirm the current quarter's official IFTA matrix before filing (this quarter's matrix is not final until December 4, 2026). Every state compared is on the IFTA rates by state hub.
IFTA tax rates in Florida
Florida's IFTA rate is a blend: state-level taxes plus the statewide average of county local option fuel taxes, per the Florida DOR and IFTA Inc. matrix:
| Fuel type / component | Rate | Notes |
|---|---|---|
| Diesel (IFTA blended rate) | 41.0¢/gal ($0.410) | The figure for your return's diesel line as of Q4 2026 |
| Gasoline (IFTA blended rate) | 41.1¢/gal ($0.411) | A rare state where gasoline edges above diesel |
| — State motor fuel tax component | 22.0¢/gal ($0.220) | Rose from 21.5 cents on January 1, 2026 per DOR TIP 25B05-05 |
| — Local option average component | ≈19¢/gal | Ninth-cent, local option and pollutants taxes averaged across counties |
| Biodiesel / B-blends | 41.0¢/gal ($0.410) | Reported as diesel on the Florida line |
Two structural notes. First, the state-level pieces reset each January 1 — TIP 25B05-05 (November 19, 2025) moved the motor fuel tax to 22.0 cents effective January 1, 2026 — and county local option layers can change on their own schedule, so the blend drifts almost annually. Second, actual pump tax varies by county because local option taxes differ; the IFTA rate is the average that keeps filing uniform. There is no separate Florida surcharge line — the local option money is already inside the single blended rate, unlike Indiana's surcharge schedule or Virginia's two-line base-plus-additional reporting.
How Florida IFTA affects your filings
Your Florida line each quarter is Florida miles divided by fleet MPG, times $0.410 for diesel. Take a Jacksonville to Atlanta to Montgomery run at 6.5 MPG:
| State | Miles | Gallons at 6.5 MPG | Diesel rate | Tax owed |
|---|---|---|---|---|
| Florida | 300 | 46.2 | $0.410 | $18.92 |
| Georgia | 180 | 27.7 | $0.373 | $10.33 |
| Alabama | 150 | 23.1 | $0.310 | $7.15 |
| Total | 630 | 96.9 | — | $36.40 |
Florida is 48% of the miles and 52% of the tax — the premium is real but not brutal on one trip. It compounds on a Florida-dedicated fleet. Flip the fueling: buy all 96.9 gallons in Florida and you prepaid $39.74 against $36.40 owed, a wash plus a little. Buy them in Alabama and you prepaid $30.05 against $36.40, leaving $6.35 due. The refund-vs-due sign flips entirely on where the tanks were filled, which is why Florida carriers who fuel at home and run regional lanes want their rate assumptions audited every quarter. Model your own mix in the IFTA calculator and file with the quarter's matrix — Florida's January 1 resets make year-old worksheets unreliable.
Florida-based carriers file with the Florida DOR as base state; everyone else carries Florida as a line item. Deadlines are the standard four — April 30, July 31, October 31, January 31 — with late penalties typically $50 to $100 plus interest per quarter.
Fueling strategy around Florida: price minus tax
Shop by net price: pump price minus the blended tax, then check the rates ahead. The Q4 2026 neighbor map makes Florida the expensive corner of the South: Georgia 37.3 cents, Alabama 31.0, Tennessee 27.0. The plays are border plays. On I-75 out of Atlanta toward Tampa or Miami, fill in Georgia — 3.7 cents a gallon better than Florida. On I-10 lanes west of Tallahassee, Alabama's 31.0 cents is a full dime cheaper, roughly $10 per hundred gallons. Southbound into Florida on either spine, arrive with full tanks and buy only what the return leg needs; outbound, top off before crossing the line north or west. A hundred gallons a week shifted from Florida pumps to Alabama pumps is about $520 a year in tax timing. Anchor the weekly call against the diesel benchmark with the fuel surcharge guide — Florida freight rates and surcharges should be carrying the state's tax premium, not eating it.
FAQ
What is the current IFTA fuel tax rate in Florida?
As of Q4 2026, Florida's IFTA rate is 41.0 cents per gallon on diesel and 41.1 cents per gallon on gasoline, per the official IFTA Inc. tax rate matrix. The figures blend the state rate with average local option fuel taxes — always confirm the current quarter's official IFTA matrix before filing.
How is Florida's fuel tax rate put together?
Florida stacks several pieces: a state motor fuel tax (raised to 22.0 cents per gallon on January 1, 2026 per DOR TIP 25B05-05), the pollutants tax, the inspection fee, and county local option fuel taxes. IFTA uses a blended rate reflecting the statewide average of the local option components.
How often do Florida IFTA rates change?
The state-level components adjust each January 1 (TIP 25B05-05 set the January 2026 changes), and local option taxes can shift with county actions. Practically, pull the official IFTA matrix every quarter — Florida's blended IFTA rate rarely matches a prior-quarter worksheet.
Does Florida have an IFTA surcharge tax like Indiana or Virginia?
No separate surcharge schedule. Florida files one rate per fuel type on the IFTA return; the local option and pollutant components are already blended into the single 41.0-cent diesel figure. Indiana and Virginia's two-line structures do not apply.
How do I calculate the fuel tax owed for miles driven in Florida?
Taxable gallons = Florida miles divided by your truck's MPG. Tax owed = taxable gallons times $0.410 (diesel, Q4 2026). At 6.5 MPG, 300 Florida miles burn 46.2 gallons and owe about $18.92 to Florida on your IFTA return.
Where should I buy fuel around Florida to lower my IFTA bill?
Florida diesel at 41.0 cents is the highest rate in the Southeast. Georgia runs 37.3 cents and Alabama 31.0 — cross the state line with full tanks, top off in Georgia on the I-75 or I-95 corridors, and fill in Alabama on western Florida lanes.
