Loudoun County Property Appraiser 2026: Search Assessments, Parcel Maps & Tax Records
If you searched for the Loudoun County property appraiser, Virginia uses a different office name. Loudoun County real estate assessments are handled by the Office of the Commissioner of the Revenue, not an agency formally called the Property Appraiser.
Use the county’s Real Property Assessment Database to check a parcel, assessed value, property characteristics and tax information. Use WebLogis when you need a parcel map, nearby properties, district boundaries or other GIS layers.
The Treasurer handles tax bills and payments, while assessment reviews and Board of Equalization appeals follow separate procedures. The sections below route each task to the correct official system.
Loudoun Does Not Have an Office Officially Called the “Property Appraiser”
Virginia’s local government structure differs from Florida and several other states. In Loudoun County, the Commissioner of the Revenue is responsible for real estate assessment. The Treasurer handles billing and collection.

| Find parcel on a map | Loudoun County GIS | WebLogis Mapping |
| Question assessed value | Commissioner of the Revenue | Assessment Appeal Guide |
| File formal assessment appeal | Board of Equalization | BOE Appeal Information |
| Pay real estate tax | Loudoun County Treasurer | Official Tax Payment Options |

How to Search Loudoun County Property Records
The official Real Property Assessment Database is the fastest place to check Loudoun property assessment and parcel information. The county’s public system supports searches using parcel and address information, including Parcel ID and tax-map data.
Open the official Real Property Search
Start with Loudoun County’s assessment database rather than a third-party property profile.

For an address, simplify the street entry
Loudoun’s search guidance recommends leaving off the street suffix when an address search does not return the expected result.
Confirm the correct parcel
Match the address, Parcel ID, legal description and property characteristics before relying on the assessment.

- Enter only the information needed to narrow the search.
- If an address fails, retry without the street suffix.

How Loudoun County Real Estate Assessments Work in 2026
Virginia real estate is assessed at 100% of fair market value. Loudoun reassesses property annually, with the assessment representing value as of January 1.
Assessment notices for 2026 were mailed in February. Loudoun explains that valuation staff review physical property information and market evidence, including valid sales from the prior year.
Before assuming the assessment is wrong
- Confirm living area and building characteristics.
- Review land acreage and property type.
- Check whether new construction was added.
- Open the parcel’s neighborhood sales information.
- Compare properties with similar age, size, acreage and amenities.
- Separate disagreement with market value from disagreement with the tax rate.

2026 Loudoun Assessment Appeal Deadlines & What Evidence Helps
Loudoun provides three main routes for challenging an assessment: an administrative review through the Commissioner of the Revenue, an appeal to the Board of Equalization, and a separate Circuit Court appeal.
Check the underlying property data
If living area, condition or another property characteristic is inaccurate, call 703-777-0269 to discuss an inspection with an appraiser.
Review comparable sales
Open your parcel record and review neighborhood sales. Focus on genuinely similar properties rather than simply finding a lower assessment nearby.
Identify the basis of your appeal
Loudoun recognizes issues such as incorrect fair market value, inaccurate property characteristics or lack of uniformity with comparable properties.
Use the correct appeal level
The 2026 administrative-review deadline was March 16. Board of Equalization appeals were due June 1, 2026.
After opening the appeal page
- Review the reasons Loudoun accepts for an assessment challenge.
- Check whether the administrative or BOE deadline still applies to your situation.
- Gather comparable sales and documents showing any factual property error.
- Submit the applicable review or appeal form through the official route.
- If the 2026 administrative and BOE deadlines have passed, contact the county before assuming no further remedy exists; Circuit Court is a separate appeal route.
