[ARCHIVED] 2023 Real Estate Assessments Available Online

Real Estate Assessments online

Loudoun County Commissioner of the Revenue Robert S. Wertz Jr. announces that Loudoun County real estate assessments for tax year 2023 are now available online at Printed assessment notices will be mailed to property owners the week of February 6, 2023.  

These assessment notices, which are not tax bills, communicate to property owners the value of their real property as of January 1, 2023, and are reflective of real estate market activity that occurred during 2022. 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 10, 2023. Thereafter, appeals may be made to the Board of Equalization until June 1.  

The county’s total taxable real estate is $129.9 billion, an increase of 14.9% over last year. The typical existing single family detached property saw a year-over-year increase in value of 7.5% and the average attached townhome was up 5.9%.  Commissioner Wertz stated, “We saw continued increases in sales prices of residential real estate in the county last year which peaked mid-year and began to taper off by the end of 2022.”  He continued, “Regarding commercial real estate, Loudoun is all about data centers which now comprise 58 percent of the commercial tax base and 14 percent of the overall value of real estate in the county.”  The total value of taxable commercial property in the county climbed to $31.7 billion, an increase of 22.4% compared to 2022.  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 can be found on the assessment notice.

Taxpayers are encouraged to connect with the Commissioner of the Revenue’s office virtually since most transactions can be done online. For more information, visit or contact the Office of the Commissioner of the Revenue at 703 777-0260 weekdays during regular business hours of 8:30 a.m. – 5:00 p.m. or by email.
