Oregon Mileage Tax Account Setup
What Is the Oregon Mileage Tax?
The Oregon Weight-Mile Tax (WMT) applies to commercial carriers with vehicles over 26,000 lbs. operating on public roads in Oregon. Instead of a fuel tax, Oregon charges a tax based on the number of miles traveled and the weight of the vehicle.
Who Needs a Mileage Tax Account in Oregon?
- Any carrier operating vehicles over 26,000 pounds in Oregon
- Out-of-state trucking companies entering Oregon
- Owner-operators and fleets delivering, picking up, or passing through Oregon
- Leased drivers operating qualifying vehicles in the state
What’s Required for Oregon WMT Registration
- USDOT Number and Federal EIN
- Business name and mailing address
- Vehicle information: VIN, weight, year, and plate number
- Proof of insurance
- Operating authority or lease agreement (if applicable)
- Oregon surety bond (may be required for new accounts)
How Oregon’s Weight-Mile Tax Works
Taxes are calculated based on vehicle weight and total miles traveled on Oregon highways. Carriers must track and file these miles through monthly reports submitted to the Oregon Department of Transportation (ODOT).

Frequently Asked Questions
- Do I need to file every month?
- Yes, Oregon requires monthly returns from all active WMT accounts—even if no miles were traveled.
- What if I only drive in Oregon once?
- You may qualify for a temporary trip permit, but regular operations require a WMT account and decal.
- Is the Weight-Mile Tax in addition to IFTA?
- Yes. Oregon does not charge fuel tax but still participates in IFTA for interstate reporting. WMT is a separate obligation.
