Gasoline Tax Rates by State

EXAMPLE:

Florida:

The statewide excise tax is 14.5 cents per gallon for gasoline and 27.2 cpg for diesel.
The 14.5 cents represents 10.5 cpg sales tax plus 4 cpg excise tax. Gasoline tax rate increased .2 cpg on 1/1/05.
Tax rate changes annually based on CPI.
Does not include 2.2-cpg tax/fee for environmental inspection purposes (5 cents per barrel tax for the Water Quality Assurance Trust Fund, 80 cents per barrel for the Inland Protection Trust Fund, 2 cents per barrel for the Coastal Protection Trust Fund and 1/8 cents per gallon for weights and measures inspection fee).
Gasoline rate also does not include additional minimum 9.9 to 17.8 cent per gallon local option tax portion with the weighted average of 14.6 cents per gallon.
Therefore, depending on where you live in Florida, your overall gasoline tax can vary from an average of 52.9 cents per gallon to 45 cents per gallon.

Something missing on all this is severance tax. We have 39 oil producing states and each of those states charge a severance tax on all crude coming from they’re states. Texas has a 4.6% severance tax, or 5.29 per 42 gallon barrel.
