How Louisiana and California build their gasoline tax
Louisiana's 20.93¢/gal total is 20¢/gal excise and 0.93¢/gal other fees (rank #44). California's 70.92¢/gal is 61.2¢/gal excise and 9.72¢/gal fees (rank #1).
Federal tax does not change the winner: both states add 18.5¢/gal, so the combined gap equals the state gap (49.99¢/gal combined).
“Other fees” can include environmental, inspection, or storage charges. Percentage-based sales or gross-earnings taxes on fuel may still understate retail tax in some states.
Annual cost: Louisiana vs California
State fuel tax ≈ (miles ÷ MPG) × (¢/gal ÷ 100). At 12,000 miles and 25 MPG (480 gallons), Louisiana is about $100.46 and California about $340.42 in state tax alone.
Raise mileage or lower MPG and the dollar gap scales linearly. The ladder on this page shows 12k/15k miles and 20/30 MPG scenarios so you can match your commute.
Federal tax on those same gallons is about $88.80 in either state—useful for total tax budgeting, but irrelevant to which state wins the comparison.
When Louisiana vs California gas tax matters
Relocation, remote-work base choice, and long cross-border commutes are the main reasons to compare these two rates. A few cents per gallon compounds quickly for high-mileage drivers and fleets.
Pump price is still mostly crude, refining, and distribution. A lower gas tax state can post a higher street price if wholesale markets are tight.
For business mileage, the IRS standard mileage rate or actual expenses already embed fuel tax—there is no separate personal gas-tax deduction for commuting.
