CAUTION

The weight declared for registering a vehicle in a state may affect the taxable gross weight used to figure the tax.

State registration by specific gross weight. If the vehicle is registered in any state that requires a declaration of gross weight in a specific amount, including proportional or prorated registration or payment of any other fees or taxes, then the vehicle’s taxable gross weight must be no less than the highest gross weight declared for the vehicle in any state. If the vehicle is a tractor-trailer or truck-trailer combination, the taxable gross weight must be no less than the highest combined gross weight declared.

State registration by gross weight category. If the vehicle is registered in any state that requires vehicles to be registered on the basis of gross weight, and the vehicle isn’t registered in any state that requires a declaration of specific gross weight, then the vehicle’s taxable gross weight must fall within the highest gross weight category for which the vehicle is registered in that state.

State registration by actual unloaded weight. If the vehicle is registered only in a state or states that base registration on actual unloaded weight, then the taxable gross weight is the total of the three items listed under Taxable Gross Weight , earlier.

Special permits. In determining a vehicle’s taxable gross weight, don’t consider weights declared to obtain special temporary travel permits. These are permits that allow a vehicle to operate:

  1. In a state in which it isn’t registered,

  2. At more than a state’s maximum weight limit, or

  3. At more than the weight at which it is registered in the state.

However, special temporary travel permits don’t include permits that are issued for your vehicle if the total amount of time covered by those permits is more than 60 days or (if issued on a monthly basis) more than 2 months during a tax year.
