Loudoun County property tax appeals
Appeal Season is a property tax appeal co-pilot. We are expanding county by county to high-tax areas like Loudoun County. We are not there yet, so we cannot check a Virginia assessment today. Leave your email and we will tell you the day we cover Loudoun County, and nothing else.
Virginia assesses at full market value, and each locality sets its own appeal deadline (independent cities assess separately). You usually ask the assessor for a review first, then appeal to a local board of equalization. An appeal makes sense when comparable sales show your value is too high.
- Recent comparable sales show your assessment is above market value.
- Your home is assessed higher than similar homes nearby.
- The record has wrong facts about your home.
- Your bill went up but your assessment is fair. The tax rate is set separately.
- You missed your locality's deadline. Each county and city sets its own.
Read the full explanation
In Virginia, your local assessor sets your home's value at 100 percent of fair market value, and you appeal that value, not your tax bill. Deadlines are set locally, not by one statewide date, and independent cities assess separately from counties, so you check your own locality's schedule. Most localities let you ask the assessor for a review first, then appeal to a local board of equalization. An appeal helps when recent comparable sales show your assessment is above market, or when it is uneven against similar homes. It usually will not help just because your bill went up, since the tax rate is set separately. This is general information, not tax advice.
