Kentucky (KY) Trucking Compliance: Filings, Registrations & Permits

✦ The quick answer

Kentucky-based and out-of-state carriers running heavy trucks on Kentucky highways must keep the core federal filings current (USDOT/MCS-150, UCR, IFTA, IRP, and Form 2290 HVUT) AND register for the Kentucky Weight Distance Tax (KYU), a per-mile weight-distance tax on vehicles with a combined gross weight of 60,000 lbs or more. The KYU number and its quarterly mileage return are the single biggest thing that sets Kentucky apart from states with no mileage tax.

What Kentucky requires

UCR

The Unified Carrier Registration (UCR) is an annual federal program administered by the states, and Kentucky participates. If you operate commercial motor vehicles in interstate commerce, you must register and pay the UCR fee every year. Your fee bracket is based on the total number of power units (trucks/tractors) in your fleet, not on a flat per-truck rate. UCR registration opens in the fall for the following calendar year, and enforcement typically begins January 1. Brokers, freight forwarders, and leasing companies without trucks pay the smallest bracket. We help you confirm your correct fleet-size bracket, prepare an accurate registration, and validate the details before you submit it through the official UCR system. Always verify the current-year fee amounts on the official UCR site, since brackets are set annually.

Form 2290 (HVUT)

Form 2290 and the Heavy Vehicle Use Tax (HVUT) are federal, filed with the IRS, but they matter in Kentucky because the state will not register or renew a qualifying heavy vehicle without proof of payment (a stamped Schedule 1). HVUT applies to vehicles with a taxable gross weight of 55,000 lbs or more. The tax for a vehicle at 55,000 lbs is $100, plus $22 for each additional 1,000 lbs over 55,000, up to a maximum of $550 for vehicles at 75,000 lbs and above. The HVUT period runs July 1 through June 30. For vehicles in use at the start of the period in July, the deadline to file is August 31. For a newly acquired or first-used vehicle, the deadline is the last day of the month after the month you first put it on the road. Note that the federal HVUT is separate from the Kentucky Weight Distance Tax (KYU) discussed below: they are two different taxes with two different agencies. We help you calculate the correct taxable gross weight, prepare Form 2290, and validate your entries so your Schedule 1 comes back clean for your Kentucky registration.

MCS-150

Your USDOT number and the MCS-150 form are how FMCSA tracks your carrier identity, fleet size, mileage, and operation type. Every interstate carrier and many intrastate Kentucky carriers need a USDOT number, and the MCS-150 must be updated at least every two years (this is the biennial update) on a schedule tied to your USDOT number. Missing the biennial update can deactivate your USDOT number and put your operating authority at risk. Kentucky uses your federal USDOT number and FEIN to tie together your KYU weight-distance account, IFTA, and IRP records, so keeping FMCSA data accurate keeps your state credentials clean too. We help you keep your MCS-150 accurate (mileage, power-unit count, contact details), guide you through the biennial update timing based on your USDOT number, and validate the data before you file it with FMCSA.

IFTA

Kentucky is a member of the International Fuel Tax Agreement (IFTA). If you operate qualified motor vehicles across state lines, you base your IFTA license in Kentucky (your base jurisdiction) and file a single quarterly fuel tax return covering all member states and provinces. A qualified vehicle generally has two axles and a gross weight over 26,000 lbs, three or more axles regardless of weight, or is used in combination over 26,000 lbs. You get Kentucky IFTA decals and a license, then report total miles and fuel purchased per jurisdiction each quarter so taxes net out correctly. Quarterly returns are due the last day of the month following each quarter: April 30, July 31, October 31, and January 31. Important: IFTA covers fuel tax only. Kentucky's Weight Distance Tax (KYU) is a separate mileage-based tax that you must file on top of IFTA, and in Kentucky both are administered by the Division of Motor Carriers. We help you organize trip and fuel data, calculate your quarterly figures, and validate the IFTA return before you file it with the Kentucky Transportation Cabinet.

IRP

The International Registration Plan (IRP) lets you register your trucks once in Kentucky and get apportioned plates that are valid in all member jurisdictions, with registration fees split based on the miles you run in each state or province. Kentucky IRP is handled by the Kentucky Transportation Cabinet's Division of Motor Carriers. You'll report your fleet's distance by jurisdiction (actual miles for renewals, or estimated miles for a brand-new operation), and your Kentucky apportioned credentials and cab card list every jurisdiction you're authorized to run in. IRP, IFTA, and the KYU weight-distance tax all rely on accurate mileage records, so good recordkeeping serves all three programs at once. We help you assemble your jurisdiction mileage, prepare your IRP application or renewal, and validate it before you submit to the Kentucky Transportation Cabinet.

Permits

Beyond the core federal programs, Kentucky carriers face several state-specific credentials. The big one is the Kentucky Weight Distance Tax license (KYU number): before operating a qualifying vehicle (combined gross weight 60,000 lbs or more) on Kentucky highways, you must obtain a KYU number and then file the quarterly KYU mileage return. Carriers that do not run regularly in Kentucky can instead buy a temporary KYU/weight-distance trip permit for an individual trip. Kentucky also issues fuel trip permits for occasional non-IFTA travel and overdimensional (oversize/overweight) permits through the Division of Motor Carriers for loads exceeding legal size or weight limits. Intrastate for-hire carriers may have additional Kentucky operating authority, insurance, and registration obligations. We help you identify which Kentucky permits, numbers, and authority types apply to your operation, prepare the paperwork, and validate it. Always confirm current requirements and fees directly with the Kentucky Transportation Cabinet Division of Motor Carriers before you rely on them.

Kentucky-specific requirements

What truly sets Kentucky apart is the Kentucky Weight Distance Tax (commonly called the KYU tax), a weight-distance tax that is separate from and on top of IFTA fuel tax. Any vehicle with a combined licensed gross weight of 60,000 lbs or more must obtain a KYU number and then file a quarterly weight-distance return reporting the miles driven on Kentucky public highways, paying tax per mile (the rate is a small fraction of a cent per mile, currently around 2.85 cents per mile, but always verify the current rate). This applies to both Kentucky-based and out-of-state carriers for the miles they run in Kentucky. Kentucky is one of only a handful of states with this kind of mileage tax; the others you are most likely to encounter are New York (HUT), New Mexico, and Oregon, each with its own separate weight-distance return. Carriers who only pass through Kentucky occasionally can buy a temporary KYU trip permit instead of holding a full KYU account. Kentucky also requires the AVIS/intrastate authority for purely in-state for-hire operations and issues its own fuel trip permits for non-IFTA travel, so the Kentucky compliance stack is meaningfully heavier than in no-mileage-tax states like Tennessee or Indiana.

Frequently asked questions

What is the Kentucky Weight Distance Tax (KYU) and do I have to pay it?+

The KYU tax is a weight-distance tax Kentucky charges for operating heavy trucks on its public highways. If your vehicle has a combined licensed gross weight of 60,000 lbs or more, you must obtain a KYU number and file a quarterly weight-distance return reporting your Kentucky miles and paying tax per mile. It applies to both Kentucky-based and out-of-state carriers for the miles they run in Kentucky. It is separate from IFTA and from the federal Form 2290 HVUT.

How is the KYU tax different from IFTA and from the Form 2290 HVUT?+

They are three separate taxes. IFTA is a quarterly fuel tax that nets out fuel taxes across states. Form 2290 HVUT is an annual federal tax paid to the IRS based on a vehicle's gross weight. The KYU tax is a Kentucky state mileage (weight-distance) tax based on how many miles you drive on Kentucky highways. You can owe all three at once, and we help you keep each one straight and prepared correctly.

How much is the Form 2290 Heavy Vehicle Use Tax?+

For a vehicle with a taxable gross weight of 55,000 lbs, the HVUT is $100. Add $22 for each additional 1,000 lbs over 55,000, up to a maximum of $550 for vehicles at 75,000 lbs or more. The tax period runs July 1 to June 30, and the filing deadline for vehicles used in July is August 31. Kentucky needs your stamped Schedule 1 to register the vehicle.

Do out-of-state trucks need a KYU number?+

Generally yes, if the vehicle has a combined gross weight of 60,000 lbs or more and runs on Kentucky highways. The KYU tax applies based on miles driven in Kentucky, not on where the carrier is based. Carriers that only travel through Kentucky occasionally can buy a temporary KYU trip permit for that trip instead of holding a full quarterly account. Verify current weight thresholds and permit options with the Kentucky Transportation Cabinet Division of Motor Carriers.

When are my Kentucky KYU and IFTA returns due?+

Both the KYU weight-distance return and the IFTA fuel tax return are filed quarterly and are due the last day of the month after each quarter: April 30, July 31, October 31, and January 31. Keep detailed mileage and fuel-purchase records, because that data drives your IFTA return, your KYU return, and your IRP renewal all at once.
