‼️ Weight-Mile Tax (WMT) Changes Coming in 2027 ‼️
Due to House Bill 3991 last year, ODOT is preparing for important changes to the weight-mile tax (WMT) structure that will take effect on July 1, 2027. The new structure will greatly simplify WMT reporting requirements and administration for motor carriers.
**ODOT will be at the OTA Annual Leadership Convention & Exhibition to explain these changes in detail and answer your questions**
Key Changes
• The number of WMT tax rates will be reduced from 85 rates to 10 rates.
• Tax weight will be the same as registration weight.
• Vehicles will be taxed based only on the registered weight.
• Carriers will no longer need to declare or report multiple weights for different vehicle configurations.
• The $5 suspension fee will be eliminated.
