Loudoun Commissioner of the Revenue Robert S. Wertz Jr. announces that Loudoun County real estate assessments for tax year 2024 are now available online at Printed assessment notices were recently mailed and property owners should begin receiving them this week.  

These assessment notices, which are not tax bills, communicate to property owners the value of their real property as of January 1, 2024, and are reflective of real estate market activity that occurred during 2023. The assessed value in conjunction with the tax rate to be set by the Board of Supervisors in April provides the basis for real estate tax bills that will be due on June 5 and December 5. Property owners who believe their assessments are incorrect may file an Application for Review with the Commissioner online at by March 18, 2024. After that date, appeals may be made to the Board of Equalization until June 3.  

The county’s total taxable real estate is $144.1 billion, an overall increase of 12.9%. The typical existing single-family detached property saw a year-over-year increase in value of 4.7% and the average attached townhouse was up 5.0%. Commissioner Wertz stated, “Sales prices of residential real estate climbed in the county again last year mainly due to limited supply.” He continued, “Regarding commercial real estate, data centers saw the largest increase in values of all types of commercial property.” The total value of taxable commercial property in the county is $39.5 billion, an increase of 22.6% compared to 2023. These figures are averages and property owners may experience assessment changes that are more or less than the average.  

Property owners may communicate with their respective appraiser whose name and contact information is listed on the assessment notice.

More information is online at or by calling the Commissioner of the Revenue’s office at 703-777-0260 weekdays during regular business hours, 8:30 a.m. – 5:00 p.m., or by sending an email.
