Loudoun County Commissioner of the Revenue Robert S. Wertz Jr. announces that Loudoun County real estate assessments for tax year 2021 are now available online at Printed assessment notices will be mailed to property owners this week. 

The assessment notices, which are not tax bills, communicate to property owners the value of their real property as of January 1, 2021, and are reflective of real estate market activity that occurred during 2020. 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 7 and December 6. Property owners who believe their assessments are incorrect may file an Application for Review with the Commissioner of Revenue online at by March 8, 2021. Thereafter, appeals may be made to the Board of Equalization until June 1.  

The county’s total taxable real estate is $95.1 billion, an overall increase of 5.8%. The typical existing single family detached property saw the largest average year-over-year increase in value of 7.2% and the average attached townhome was up 6.4%. The total value of taxable commercial property in the county is $18.6 billion, a decline of 5.7% compared to 2020. 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.

To protect the safety of taxpayers and staff and slow the spread of COVID-19, taxpayers are encouraged to connect with the Commissioner of the Revenue’s office virtually. Most transactions with the office can be completed 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.
