SUMMARY ANALYSIS
Prior to 2014, owners or operators of Florida-licensed motor vehicles powered by natural gas fuels were
required to pay an annual decal fee for each such vehicle. In 2013, the Legislature passed a bill to “help
reduce transportation costs in this state and encourage freight mobility investments that contribute to the
economic growth of the state.” To accomplish these goals, the bill created a 5-year rebate program for certain
costs involved in the conversion, purchase, or lease of natural gas fuel fleet vehicles, eliminated the annual
decal fees for natural gas vehicles, and created a new tax structure whereby natural gas fuels would be taxed
on a per unit basis beginning January 1, 2019. In 2018, the legislature delayed the start date of this new tax
structure by an additional 5 years to January 1, 2024. Accordingly, natural gas fuels have not been subject to
state fuel taxes since January 1, 2014.
The bill provides for a 2-year delay of the imposition of natural gas fuel taxes that would otherwise go into
effect January 1, 2024. The bill changes the effective date of the imposition of these taxes to January 1, 2026.
To conform to the delayed imposition of these taxes, the bill:
Extends by 2 years (from December 31, 2023, to December 31, 2025) the expiration of the current flat
penalty scheme that applies to any person who acts as a natural gas retailer without a valid natural gas
fuel retailer license, and delays by 2 years (from January 1, 2024, to January 1, 2026) the effective date
of a new penalty scheme that is based on a percentage of the tax assessed during the period of
unlicensed operations.
Delays by 2 years (from February 2024 to February 2026) the date by which natural gas fuel retailers
must file monthly reports with DOR for the purpose of determining the amount of natural gas fuel taxes
imposed.
The bill delays by 2 years the imposition of natural gas fuel taxes until January 1, 2026, resulting in delayed
collection of revenues from the taxes.
The bill provides an effective date of July 1, 2023.
This docum ent does not reflect the intent or official position of the bill sponsor or House of Representatives .

I. SUBSTANTIVE ANALYSIS
A. EFFECT OF PROPOSED CHANGES:
Present Situation
Taxation of Natural Gas Fuel
Pre-2014
Prior to 2014, natural gas fuels such as compressed natural gas (CNG) and liquid petroleum gas (LPG)
were defined in Florida law as “alternative fuels” when used to fuel motor vehicles.1 In lieu of the excise
tax imposed on diesel fuel under the law, owners or operators of Florida-licensed motor vehicles
powered by alternative fuels were required to pay an annual decal fee for each such vehicle.2 These
annual fees ranged from $199.10 to $380.10 per vehicle, depending on the vehicle’s size and weight. 3
The sale of alternative fuels also was subject to sales tax imposed under ch. 212, F.S. 4
With certain exceptions, Florida law prohibited a person from acting as a retailer of alternative fuel
unless that person held a valid license as a retailer of alternative fuel issued by the Department of
Revenue (DOR).5 Any person acting as such without a license was subject to a penalty of 25 percent of
the tax assessed on total purchases during the unlicensed period. 6 Every person who operated as a
retailer of alternative fuel, with certain exceptions, was required to report monthly to DOR and pay tax
on all fuel purchases.7
Revenues from the annual decal fees were deposited into the State Alternative Fuel User Fee Clearing
Trust Fund.8 After deducting a specified service charge, the proceeds in the trust fund were distributed
as follows:
One-half of the proceeds to the State Transportation Trust Fund (STTF).
50 percent of the remainder to the State Board of Administration for distribution in accordance
with the Florida Constitution.
25 percent of the remainder to the Revenue Sharing Trust Fund for Municipalities.
25 percent of the remainder to the counties for specified public transportation purposes,
distributed as provided by law.
Current Law
In 2013, the Legislature passed CS/CS/HB 579 to ““help reduce transportation costs in this state and
encourage freight mobility investments that contribute to the economic growth of the state.”9 To
accomplish these goals, the bill created a 5-year rebate program for natural gas fuel fleet vehicles and
exempted natural gas fuels from state fuel taxes for 5 years. The Natural Gas Fuel Fleet Vehicle
Rebate program provided $6 million per fiscal year, from FY 2013-14 through FY 2017-18, to fund
rebates for the purchase, conversion, or lease of natural gas fuel fleet vehicles. Further, effective
January 1, 2014, the bill eliminated the annual decal fee for natural gas vehicles. The 2013 bill
replaced it with a new tax structure that creates a “per motor fuel equivalent gallon” tax rate to become
1 S. 206.86(4), F.S. (2012).
2 S. 206.877, F.S. (2012). The excise tax imposed on diesel fuel was applied to the purchase of alternative fuels by
operators of vehicles licensed in other states.

DATE: 3/8/2023
effective January 1, 2019. 10 In 2018, the legislature delayed the effective date of these taxes to
January 1, 2024.
Pursuant to the current structure, the following taxes will be imposed on natural gas fuel11 effective
January 1, 2024:12
An excise tax of 4 cents upon each motor fuel equivalent gallon 13 of natural gas fuel.
An additional tax of 1 cent upon each motor fuel equivalent gallon of natural gas fuel, which is
designated as the “ninth-cent fuel tax.”
An additional tax of 1 cent on each motor fuel equivalent gallon of natural gas fuel by each
county, which is designated as the “local option fuel tax.”
An additional tax on each motor fuel equivalent gallon of natural gas fuel, designated as the
“State Comprehensive Enhanced Transportation System (SCETS) Tax.” The tax rate must be
determined by DOR each calendar year, rounded to the nearest tenth of a cent, for the following
12-month period beginning January 1. The rate is calculated by adjusting the “initially
established tax rate of 5.8 cents per gallon” by the percentage change in the average of the
Consumer Price Index issued by the United States Department of Labor for the most recent 12-
month period ending September 30.
An additional tax on each motor fuel equivalent gallon of natural gas fuel “for the privilege of
selling natural gas fuel,” designated as the “fuel sales tax.” The tax rate must be determined by
DOR each calendar year, rounded to the nearest tenth, for the following 12-month period
beginning January 1. The rate is calculated by adjusting the “initially established tax rate of 9.2
cents per gallon” by the percentage change in the average of the Consumer Price Index issued
by the United States Department of Labor for the most recent 12-month period ending
September 30.
In sum, prior to any of the required annual index-based adjustments by DOR, natural gas fuel will be
taxed at a rate of at least $0.21 cents per motor fuel equivalent gallon beginning January 1, 2024.14
Revenues from the natural gas fuel tax will be deposited into the State Alternative Fuel User Fee
Clearing Trust Fund to be distributed as follows:15
The revenues from the SCETS tax and fuel sales tax will be transferred to the STTF.
The revenues from the excise tax will be distributed as follows:
o 50% will be transferred to the State Board of Administration for distribution in
accordance with the Florida Constitution.
o 25% will be transferred to the Revenue Sharing Trust Fund for Municipalities.
o 25% will be distributed to the counties for specified public transportation purposes,
distributed as provided by law.
The revenues from the ninth-cent fuel tax and the local option sales tax will be deposited into
the Local Alternative Fuel User Fee Clearing Trust Fund and returned monthly to the
appropriate counties.
10 Id. The provisions of the bill related to taxation of natural gas fuel are codified as Part V of Ch. 206, F.S., consisting of
Ss. 206.9951 – 206.998, entitled “NATURAL GAS FUEL.”
11 “Natural gas fuel” is defined as “any liquefied petroleum gas product, compressed natural gas product, or combination
thereof used in a motor vehicle as defined in s. 206.01(23). This term includes, but is not limited to, all forms of fuel
commonly or commercially known or sold as natural gasoline, butane gas, propane gas, or any other form of liquefied
petroleum gas, compressed natural gas, or liquefied natural gas. This term does not include natural gas or liquefied
petroleum placed in a separate tank of a motor vehicle for cooking, heating, water heating, or electric generation.” S.
206.9951(2), F.S.
12 S. 206.9955, F.S.
13 “Motor fuel equivalent gallon” is defined as “the volume of natural gas fuel it takes to equal the energy content of 1
gallon of motor fuel.” s. 206.9951(1), F.S. The conversion rates for various types of natural gas fuels is provided in s.
206.9955, F.S.
14 The law is unclear as to whether the index-based adjustments were to begin with the effective date of the law (January
1, 2014) or the effective date of the new tax rates (January 1, 2024).
