Weight-distance tax calculator
Four states tax heavy trucks on miles driven: Kentucky, New Mexico, New York, and Oregon. This tool is the home for those estimates. Per-state bracket tables load here as each state's pages go live; until then, each program card below points to the agency table that holds the current numbers, so nothing on this page is ever guessed.

Per-state estimate
Estimate only, not a returnLoading the calculator inputs…
Pick a state and weight bracket, then enter your taxable miles. The estimate appears here.
The four programs at a glance
Each program registers you on its own credential, files on its own schedule, and publishes its own bracket table. The cards below carry the sourced program facts; the full state-by-state breakdown, including the states without a mileage tax, lives on the weight-distance tax states comparison.
Kentucky: Kentucky Weight Distance Tax (KYU)
- Credential
- KYU Number
The current bracket table lives on the agency page cited above.
The rest of the tax stack
A truck that owes a mileage tax in one of these states almost always owes the rest of the stack too. Quarterly fuel tax runs through the IFTA calculator with rates from the IFTA tax rates browser. Add apportioned plates via IRP registration, the annual UCR fee, and the federal highway use tax on Form 2290 to see the true cost of the lane.
Frequently asked questions
Which states does this calculator cover?
- Kentucky, New Mexico, New York, and Oregon. They are the only US states that tax heavy trucks per mile on top of fuel tax and registration. Every other state and DC levies no weight-distance tax, so there is nothing to calculate elsewhere.
Which states can the tool total today?
- The states whose sourced bracket tables have landed in the rate store. A state still marked pending points to the agency table until its rollout lands.
How will the estimate work once a state’s table lands?
- The same way the agencies compute it: the published rate for your registered or gross weight bracket multiplied by your taxable miles in the state. The tool will pull that bracket rate from the stored table, cite it, and multiply. Returns still handle exemptions, credits, and rounding on their own.
Is a weight-distance tax part of my IFTA return?
- No. IFTA settles per-gallon fuel tax between member jurisdictions in one quarterly return. A weight-distance tax is a separate per-mile tax with its own account, return, and deadlines in each of the four states, and Oregon uses its Weight-Mile Tax in place of a fuel tax on heavy trucks.
