What Texas charges at the pump

  • Here is what Texas takes at the pump. Twenty gallons carries $4 of state fuel tax. Five hundred gallons over a year carries $100. It is built into the posted price, so nobody ever sees it itemized, and the state ranks 42 nationally on the rate.
  • In Texas diesel is taxed no more heavily than ordinary fuel. Twenty gallons carries $4 against $4. That is unusual — most of the country adds a premium to diesel — and it quietly matters to anyone running a van or a truck here.
  • Texas keeps it simple. There are no separate inspection or environmental charges reported on top of the fuel tax here, so the main rate is the whole of what the state adds to a gallon.
  • State fuel excise in Texas amounts to $4 per twenty-gallon fill and $100 per five hundred gallons, with a rate ranking 42 nationally. ⚠️ The federal component is excluded. Unlike sales tax, fuel excise is embedded in the posted price rather than added at the register, which is why it is among the least visible taxes most households pay routinely.
  • Diesel and gasoline are taxed at parity or with diesel favored in Texas, at $4 and $4 per twenty gallons respectively. ⚠️ Since most states impose a diesel premium, the absence of one here is a structural feature worth noting in any comparison of operating costs across neighboring jurisdictions.
  • Texas reports no additional motor fuel levies apart from its principal excise, so the headline rate represents the state's full per-gallon charge. ⚠️ That makes its position in a national rate table more directly comparable than that of states which levy separately-reported inspection or environmental charges alongside the main rate.

Gasoline, diesel, and the charges reported separately

Per-gallon rates are shown as Texas publishes them, to a tenth of a cent. The money columns are what those rates come to on a 20-gallon fill and across 500 gallons. Federal tax is charged on top of all of it and is not included.

What this page cannot tell you

  • ⚠️ Federal fuel tax is charged on top of all this and is not included above. It is the same everywhere in the country.
  • The tank and the year here are round reference amounts, not a guess at your driving. Your own total scales directly with the gallons you actually buy in Texas.
  • And some places add local fuel taxes of their own on top of the state's. Those are not counted here.
  • ⚠️ Federal motor fuel excise applies in addition to every figure on this page and is deliberately excluded, being uniform nationally. Including it would raise each state's figure by the same amount and compress the differences this page exists to show.
  • Quantities are reference points rather than estimates of consumption: liability is strictly proportional to gallons purchased, so any household's figure is this one scaled by its own volume. ⚠️ Fuel purchased outside Texas is taxed by the state where it is bought, which is why the figures describe purchases rather than mileage.
  • Local option fuel taxes exist in a number of states and are excluded from these figures, which cover the state levy only. Where a county or city in Texas imposes its own charge, the true per-gallon burden at that address exceeds what this page reports.

Questions people ask

Why is there no tax line on my fuel receipt?

It is already in the price on the sign. The levy is charged per gallon further up the chain, so there is nothing to add at the pump and nothing to itemize.

Is this a cheap state for this?

Among the lower ones — 42 of 51. A low per-unit levy does not necessarily mean a low shelf price, though: what a thing costs is mostly supply, transport and retail margin, and tax is only the part the state sets.

Is diesel taxed the same as gasoline?

No — it carries its own rate, a lower one here. States set the two separately, usually reasoning about road wear from heavy vehicles rather than about the fuel itself, so the gap between them is a policy choice rather than a chemical one.

Why does motor fuel excise not appear as a separate charge?

Motor fuel excise is levied per gallon at the distributor or terminal, not at retail, so it is embedded in the pump price and not separately stated. Because it is volumetric rather than ad valorem, liability per gallon is invariant to the retail price and its real value erodes with inflation absent legislative change.

Where does this state sit in the national distribution?

This state ranks 42 of 51, in the lower third. ⚠️ Excise rank is a poor proxy for retail price: production, distribution and retail margin dominate the final figure, and the tax component is the only part under state control.

How does the diesel rate relate to the gasoline rate here?

Diesel is taxed at a rate set independently of gasoline and is lower in this state. The differential is generally justified by road-wear attribution to heavy vehicles rather than by fuel characteristics, and several states index the two grades differently.
