How South Carolina and Georgia build their gasoline tax

South Carolina's 28.75¢/gal total is 28¢/gal excise and 0.75¢/gal other fees (rank #30). Georgia's 34.05¢/gal is 33.3¢/gal excise and 0.75¢/gal fees (rank #17).

Federal tax does not change the winner: both states add 18.5¢/gal, so the combined gap equals the state gap (5.3¢/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: South Carolina vs Georgia

State fuel tax ≈ (miles ÷ MPG) × (¢/gal ÷ 100). At 12,000 miles and 25 MPG (480 gallons), South Carolina is about $138.00 and Georgia about $163.44 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 South Carolina vs Georgia 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.
