Oregon Weight-Distance Tax
Over 26,000 lb combined you pay Oregon's Weight-Mile Tax by the mile instead of diesel tax at the pump — buy fuel Oregon-tax-free (ORS Ch. 825). The rate runs from 7.64 cents/mile at 26,001 lb up to 25.12 cents/mile at 80,000 lb (Table A), higher over that. You need a CCD account and a Weight Receipt before you enter, and you file monthly your first year, then quarterly.
How the Oregon weight-distance tax works
Over 26,000 lb combined you pay Oregon's Weight-Mile Tax by the mile instead of diesel tax at the pump — buy fuel Oregon-tax-free (ORS Ch. 825). The rate runs from 7.64 cents/mile at 26,001 lb up to 25.12 cents/mile at 80,000 lb (Table A), higher over that. You need a CCD account and a Weight Receipt before you enter, and you file monthly your first year, then quarterly.
What you have to do before you drive
- Applies at: Combined weight over 26,000 lb. You declare your operating weight; empty return miles are paid at the same declared weight and rate as when loaded.
- Rate: Graduated by declared combined weight (Table A, Form 735-9928, effective Jan 1, 2024 — still the rates in force). Rates rise bracket by bracket: 76.4 mills/mile ($0.0764) at 26,001-28,000 lb, up to 251.2 mills/mile ($0.2512) at 78,001-80,000 lb. Over 80,000 lb pays Table B axle-weight rates (heavy haul over 98,000 lb also pays separate Road Use Assessment Fees). HB 3991 (2025) would have simplified the tax — collapsing the roughly 85 brackets to about 10, slated for July 1, 2027 — but that package was referred to voters, who rejected it (Measure 120) in the May 2026 primary, leaving the changeover unsettled. Pull the live table before you file.
- Register: Enroll in the Weight-Mile Tax Program: open an Oregon CCD account and obtain a Weight Receipt & Tax Identifier. A Temporary Pass covers a one-off trip. ODOT may require a Highway Use Tax Bond before you operate.
- Filing: Monthly, due the last day of the following month. New accounts must file monthly for the first 12 months; after 12 consecutive months in good standing you can apply (Form 9030) to move to quarterly. You owe a report even for a zero-mile period.
Running without it
No weight-mile credential means a citation at the port of entry — the Weight Receipt or a temporary pass must be in the cab before you cross in. File late or skip a report and your account goes delinquent: ODOT adds interest, can suspend your account and plates, and can require a Highway Use Tax Bond before you run again.
