Oregon’s mileage tax is assessed against all carriers, private and for-hire, operating both intrastate and interstate with vehicles having a combined weight over 26,000 pounds. If you’re subject to the tax, it’s paid based on your vehicle’s declared weight and the distance in which the vehicle travels in Oregon. The declared weight is the heaviest weight at which the vehicle will operate in Oregon. The vehicle’s registration weight may be higher than the declared weight, but the declared weight cannot be higher than the registration weight.
Note that if you’re transporting items including but not limited to logs, poles, wood chips, sawdust, sand, gravel, rock and dirt, you can pay the weight-distance tax on a flat monthly basis. Farm vehicles operating intrastate for-hire also have the option of paying a flat monthly tax. Looking for a Oregon trip permit, we can help!
