The Layers of Gas Taxation

Gasoline is one of the most heavily taxed consumer goods in North America - but not all gas taxes are created equal. Some are flat per-gallon (or per-litre) excise charges. Some are percentage-based sales taxes calculated on the final pump price. Some are environmental levies tied to carbon emissions. And some are local transit surcharges that only apply if you happen to live in the wrong city. Here's what you're actually paying for:

🏛️

Federal Excise Tax

A flat per-unit charge set by the national government. In the US, it's 18.4¢/gal and hasn't moved since 1993. In Canada, it's 10¢/L and hasn't changed since 1995. Both go primarily into infrastructure funds.

🗺️

State / Provincial Excise

The biggest variable in what you pay. US states range from 8.95¢ (Alaska) to 70.92¢ (California) per gallon. Canadian provinces range from 7.5¢/L (Newfoundland) to 19.2¢/L (Quebec) in base road taxes.

🧾

Sales Tax (GST/HST/PST)

Some US states apply their full sales tax to gasoline (Illinois 6.25%, Indiana 7.0%). In Canada, GST (5%) or HST (13-15%) applies everywhere, calculated on the full pump price including all other taxes - a "tax on tax" effect. Connecticut's situation is unique: gasoline is exempt from CT's 6.35% sales tax, but CT levies an 8.1% Petroleum Products Gross Earnings Tax (PPGRT) at the wholesale level, which gets passed to consumers at roughly 20-28¢/gal depending on the price of oil.

🌱

Carbon / Environmental Levy

Canada's federal carbon tax hit 17.6¢/L before being eliminated April 1, 2025 in all provinces except Quebec. BC also eliminated its carbon tax the same day. Quebec runs its own cap-and-trade system, still adding ~10¢/L. Some US states have cap-and-trade programs that raise prices indirectly.

🏙️

Municipal / Transit Levies

Some cities tack on their own surcharges. Vancouver charges an extra 18.5¢/L for TransLink transit. Victoria charges 5.5¢/L. Montreal adds ~1.5¢/L. In the US, Nevada's Clark County (Las Vegas) adds up to 36¢/gal in local taxes, and Maui County in Hawaii adds 24¢/gal.

The "tax on tax" problem: In Canadian provinces with HST, the sales tax is calculated on the full pump price - which already includes federal excise, provincial road tax, and any carbon charges. You're literally paying a percentage tax on top of other taxes. In Ontario, this adds roughly 15¢/L to the bill that you'd never know about just from reading the pump sticker.

🇺🇸 United States
Section 02

The US Picture: State by State

There are no zero-tax states when it comes to gasoline. Every single one of the 50 states - plus the District of Columbia - levies some form of excise tax on gasoline, and all of them also pay the federal 18.4¢/gallon on top of that. But the range is massive. Add Alaska's state tax (8.95¢) to the federal rate and you're at 27.35¢/gal total. Do the same for California (70.92¢ state) and you hit 89.32¢/gal - more than three times as much.

Section 03

Top 5 Highest-Tax US States

California sits in a class of its own - not just because of its excise tax, but because its Low Carbon Fuel Standard (LCFS) and cap-and-trade program add an estimated additional 30-70¢/gal on top of the official tax rate, depending on how you calculate the pass-through. The official state excise is 70.92¢/gal, but the environmental regulation premium pushes true consumer costs significantly higher.

Illinois is the sneaky one on this list. With a state excise of 66.4¢/gal plus a 6.25% state sales tax applied to gasoline, Illinois drivers pay one of the highest effective tax rates as a percentage of their pump price in the country - over 26% of the total price at the pump is tax.

No US state has zero gasoline tax. Not one. The closest is Alaska at 8.95¢/gal state tax - still well above zero. And all 50 states pay the federal 18.4¢/gal on top.

Total Tax as % of Pump Price — All States

Illinois leads on percentage despite not having the absolute highest tax, because its pump price is more moderate. Alaska pays the lowest percentage despite low absolute taxes because remote supply costs push prices up. Sorted by percentage descending.

Section 04

US City and County Tax Outliers

While most US states don't allow local gas taxes, a handful of jurisdictions let counties and cities pile on additional charges that dramatically increase what drivers pay at the pump.

Washoe County, NV
Nevada — Reno metro area
+62¢/gal
Local county tax add-on

Washoe County levies a Regional Transportation Commission fuel tax that adds 62¢/gal on top of the already-low Nevada state rate of 23.81¢/gal. That makes Reno-area drivers pay more in total taxes than California drivers.

Clark County, NV
Nevada — Las Vegas metro area
+36¢/gal
Local county tax add-on

Clark County (Las Vegas) adds 36¢/gal through the RTC Fuel Revenue Indexing program. Combined with the state and federal rates, Las Vegas-area drivers pay some of the highest taxes west of Illinois.

Maui County, HI
Hawaii — Island of Maui
+24¢/gal
County surcharge

Hawaii counties can levy their own surcharges on fuel. Maui County adds 24¢/gal on top of Hawaii's already-notable state and federal rates, making it one of the highest per-gallon tax locations in the US.

New York City, NY
New York — NYC metro area
Extra layers
Petroleum Business Tax + local charges

New York's Petroleum Business Tax adds to the state's already complex fuel tax structure, and NYC's congestion pricing program (launched January 2025) effectively adds to the cost of driving in lower Manhattan.

🇨🇦 Canada
Section 05

Canada's Gas Tax Structure

Canada's fuel tax system is more layered than the US equivalent, and it just got a lot simpler. Until April 1, 2025, most Canadians were also paying a federal carbon tax that added 17.6¢/L to the price of gasoline. The new Liberal government eliminated it nationwide - except in Quebec, which runs its own separate cap-and-trade carbon pricing system that still adds roughly 10¢/L. British Columbia had its own provincial carbon tax, which it also eliminated on April 1, 2025.

Crucially, Canada's GST/HST is applied to the full pump price - meaning you pay sales tax on top of the excise taxes, the carbon tax, and everything else already baked in. This "tax on tax" structure adds meaningfully to the overall burden, especially in Atlantic Canada where the combined HST rate is 15%.

Section 06

Quebec, Vancouver & Other Canadian Outliers

Three Canadian cities add their own municipal transit taxes on fuel, and one entire province still runs a carbon pricing system that other provinces abandoned. These are the Canadian cases that stand out from the crowd.

Metro Vancouver
British Columbia — TransLink Area
+18.5¢/L
TransLink transit tax add-on

Vancouver-area drivers pay a dedicated 18.5¢/L transit levy that funds the TransLink regional transit authority. Combined with BC's provincial motor fuel tax (14.5¢/L) and the federal 10¢/L excise, the pre-sales excise burden in Vancouver reaches 43¢/L before GST - the highest in Canada.

Victoria
British Columbia — BC Transit Area
+5.5¢/L
BC Transit levy add-on

Victoria drivers pay a dedicated 5.5¢/L surcharge for BC Transit regional service. Combined with provincial and federal rates, Victoria's pre-sales excise total reaches 31¢/L. Pump prices in Victoria are generally lower than Vancouver but still among BC's highest.

Montreal
Quebec — STM Transit Area
+1.5¢/L
Municipal transit tax

Montreal adds approximately 1.5¢/L for regional transit. Quebec already has the highest provincial road tax (19.2¢/L) and is the only province still running carbon pricing, so Montreal's total tax burden is among Canada's heaviest when all layers are counted.

Quebec Province
Quebec — Cap-and-Trade Carbon Pricing
~10¢/L
Cap-and-trade carbon premium

While every other province saw its federal carbon charge eliminated April 1, 2025, Quebec runs its own cap-and-trade system that pre-dates the federal program. It continues to add approximately 10¢/L to gasoline costs. Combined with Quebec's 19.2¢/L road tax, the province carries the heaviest excise burden in Canada outside major urban transit zones.

🌎 North America Comparison

North America Gas Price Ranking

To compare US and Canadian pump prices directly, we've converted Canadian prices to USD per gallon using an approximate CAD/USD exchange rate of 0.70 (early March 2026) and the standard unit conversion (1 US gallon = 3.785 litres). This is a snapshot comparison - exchange rates and pump prices both fluctuate. The Canadian dollar's weakness against the USD in 2025-2026 means Canadian gas prices look cheaper in USD terms than they feel at home in Canadian dollars.

Note on the conversion: These USD/gal equivalents reflect the exchange rate at time of writing. At purchasing power parity, Canadian pump prices would look somewhat different. We're showing what a cross-border traveller would experience paying at the pump in each jurisdiction.
