Personal Property Assessment

Personal Property Assessment

The Commissioner of the Revenue, Robert S. Wertz, Jr. is responsible for the assessment of all personal property with taxable status in Loudoun County. Virginia state law requires Commissioners of the Revenue to use a recognized pricing guide to assess vehicles for personal property tax. Loudoun County, as well as all Virginia localities, uses the January 1, Eastern Edition of J.D. Power’s N.A.D.A. (National Automobile Dealers Association) Official Used Car Guide and the January 1, National Edition N.A.D.A. Official Older Car Guide for routine valuation purposes. These guides contain six values. Loudoun uses the "Clean Loan" value, taking into consideration four-wheel drive, special engine, and/or tandem/single axle configurations. Vehicles listed in the January 1, National Edition N.A.D.A. Classic, Collectible, Exotic and Muscle Car Appraisal Guide and Directory are valued using the low retail value, the lowest of three values listed in the guide.

Vehicles Not Listed in the Pricing Guide

If the model and year of a vehicle is not listed in the recognized pricing guide, the law permits the vehicle to be valued on the basis of percentage of original cost, to reflect fair market value. To ensure uniformity in valuation for vehicles of the same make and model, the Office of the Commissioner of the Revenue uses the Manufacturer's Suggested Retail Price (MSRP) as original cost. Prior model year vehicles not listed in the guide are assessed at 75% of the MSRP. Current model year vehicles not listed in the guide are assessed at 90% of the MSRP as listed in the New Car Cost Guide. MSRP includes the base price for the vehicle trim level, the cost of any options, packages, or extras the vehicle is equipped with.

Subsequent model year vehicles not listed in the guide are assessed at 100% of cost as reported to the Department of Motor Vehicles. Vehicles 20 to 24 years of age, which are not listed in the January 1, J.D. Power's N.A.D.A. Official Older Car Guide, are assessed at 90% of the prior year's assessment. Due to the difficult nature of determining the condition of vehicles 25 years or older, such vehicles are assessed at $100.

All trucks with a gross weight over 2 tons, motorcycles, campers, trailers, boats and motor homes are assessed based on percentage of cost.

Mobile Homes

Loudoun uses the Average Mid value published in the Wingate Appraisal Service Virginia Manufactured Housing Appraisal Guide for assessing mobile homes.


The average wholesale value listed in the Winter Edition Aircraft Bluebook Price Digest is used for assessing aircraft.

In addition to requiring valuation based on a pricing guide or cost, the Code of Virginia requires that the value of tangible personal property be fixed as of "tax day," which is January 1, regardless of when the property is purchased or located in Loudoun County.
