The Oregon Weight-Mile Tax

Oregon is one of the few states that taxes trucks by weight and miles, and it levies this tax instead of fuel tax for vehicles over the threshold. Here is who owes it, the current rate table, and how registration and filing work, every fact sourced.

By Haul Handbook editorial team· Updated Jul 19, 2026

Oregon does not tax diesel fuel through a fuel-use tax for heavy vehicles. Instead, most commercial vehicles operating in Oregon at a registration weight over 26,000 pounds pay the weight-mile tax on Oregon taxable miles, computed by declared weight (and, above 80,000 pounds, by number of axles). This replaces the diesel fuel tax that other states levy through IFTA.

The basics

Tax name
Oregon Weight-Mile Tax
Credential required
Oregon CCD account and enrollment in the Weight-Mile Tax Program (Weight-Mile Tax Enrollment Application, form 9076). Vehicles must be enrolled, or the carrier must buy a temporary pass, before operating over 26,000 pounds.
Filing frequency
Monthly by default (report and payment postmarked by the last day of the following month). A carrier with a 12-month clean filing history may apply (form 9030) to report quarterly; quarterly reports are due May 31, Aug 31, Nov 30, and Feb 28 for Q1-Q4. Carriers hauling qualifying commodities may elect flat monthly fees.
Statute
ORS Chapter 825

Alternatives: Flat monthly fee: Summary
Carriers hauling logs/poles/piling/peeler cores; wood chips/sawdust/bark dust/hog fuel/shavings; dump-body loads of sand/gravel/rock/dirt/debris/cinders/asphaltic-concrete mix/metallic ores from mines-pits-quarries tied to a construction project; or qualifying intrastate for-hire farm vehicles under 46,000 lbs may elect an annual flat fee paid monthly instead of mileage tax. The fee is per hundred pounds of declared combined weight and varies by commodity group (dump trucks, log trucks, wood-chip trucks). A fee-basis election may be changed only once per calendar year (form 9910); reports are due by the 10th of the following month.

Where it fits in the Oregon stack

The weight-distance account sits alongside IRP apportioned plates and the IFTA license; interstate carriers based in Oregon typically hold all three. The full launch order is in start a trucking company in Oregon.

Frequently asked questions

Who owes the Oregon weight-distance tax?

Carriers running vehicles over the state's weight threshold on Oregon public highways owe the tax on the miles those vehicles run there. The tables on this page carry the thresholds and the current rates, each with the official source.

Is this the same as IFTA?

No. IFTA settles fuel tax across jurisdictions; Oregon instead charges for road use by weight and miles in place of fuel tax for vehicles over the threshold, while lighter vehicles pay fuel tax at the pump. Only a handful of states levy a weight-distance tax, and Oregon is one of them.

Do I need a separate account or permit for it?

Yes, the tax has its own registration and credential, separate from your plates and IFTA license. The registration section on this page covers how Oregon issues it, with the official source linked.

Where do the rates on this page come from?

Straight from the state's published rate schedule, stored once in our rate store and rendered from there, so a rate change updates this page and the calculator together. Each rate cell links the official source.
