Real estate in Virginia is assessed at 100% of its fair market value. In Loudoun County, this means your assessed value equals your property's market value. If your home's market value is $495,000, at Virginia's 100% assessment ratio your assessed value would be $495,000, resulting in approximately $3,985 in annual taxes at the county's effective rate of 0.805% ($0.805 per $100 in assessed value).

The Appeal Process

Appeals are heard by the Board of Equalization. The Board of Equalization is responsible for reviewing appeals and determining whether a property is assessed equitably when compared with similar properties and at fair market value.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Loudoun County?

However, before appealing to the Board, you should first file an Application for Review with the Commissioner of Revenue by March 16, 2026.

You can file an Application for Review with the Commissioner of Revenue online at https://loudoun.gov/reaa by March 16, 2026. Online applications are recommended for residential properties and required for commercial properties.

The online system provides a convenient way to submit your appeal and track its status throughout the review process.
What evidence do I need for a Loudoun County property tax appeal?
For a successful property tax appeal in Loudoun County, you should gather evidence supporting one of three acceptable bases for appeal. Market Value evidence includes comparison of recent sales of properties similar to yours. Equity evidence involves comparison of properties in close proximity to yours that have similar features i.e. living area, age, acreage and amenities. Incorrect Property Data includes inaccurate information utilized to generate your assessment. Having solid documentation in any of these categories will strengthen your appeal case.
What happens at a Board of Equalization hearing in Loudoun County?
The Board of Equalization is responsible for reviewing appeals and determining whether a property is assessed equitably when compared with similar properties and at fair market value. During the hearing, you'll present your evidence to support your claim that your assessment is incorrect. Staff will consider several factors, including: Comparison of sales of properties similar to yours between January 1 - December 31 of the prior year, comparison of properties in close proximity to yours that have similar features, such as age, living area, acreage, and amenities, and accuracy of the information used to generate your assessment.
How much can I save by appealing my property taxes in Loudoun County?
The amount you can save depends on how much your property is overassessed. Since the median annual property tax bill in Loudoun County is $6,243, which is more than twice as high as the statewide median, even a modest reduction in your assessment could result in significant savings. Statistics show that about 25% of homes in America are unfairly overassessed, and pay an average of $1,346 too much in property taxes every year. With Loudoun County's high property values and tax rates, successful appeals could potentially save homeowners thousands of dollars annually.
What is the homestead exemption worth in Loudoun County?
Loudoun County doesn't offer a traditional homestead exemption like some other states. However, the county offers tax relief for residents who are 65 or older or permanently and totally disabled, with the exemption applying to the residence and up to three acres. The Board of Supervisors sets the income and net worth limits for qualifying for this relief. Additionally, veterans with 100% service-connected disabilities receive a complete exemption from paying real estate taxes on their primary residence, which can save thousands of dollars annually given the county's high property values.
Can I appeal my property tax assessment if I missed the March deadline?
Yes, you still have options if you missed the March 16 deadline for filing an Application for Review with the Commissioner of Revenue. Appeals may be made to the Board of Equalization until June 1. You may file an appeal with the Board of Equalization (BOE) by June 2, if you prefer not to use the administrative review process, miss the deadline to request a review, or disagree with the results of the review of your property's assessment. Even after the BOE deadline, you may file suit in Loudoun County Circuit Court, though this typically requires hiring an attorney.
How often does Loudoun County reassess property values?
During the annual reassessment, property values are examined and adjusted based on physical or market evidence. A reassessment is a systematic review of all properties within Loudoun County to determine a current market value as of January 1. Annual Real Estate Assessment Notices provide property owners with the value of their real property as of January 1 each calendar year. Notices for 2026 will be mailed in February. Your assessment is based on valid sales in your neighborhood that occurred between January 1 and December 31 of last year (and in some cases, earlier).
