Paying Your Loudoun County Property Taxes

Loudoun County mails real estate assessment notices every February. But it’s important to note that these notices are not tax bills. Instead, they reflect property value as of January 1 of that year based on market activity in the previous year. Both this value and the upcoming April’s tax rate combine as the base determining a property’s new annual tax bill.

Under state law, the Treasurer has to mail your property tax bill with at least two weeks’ notice before your tax bill is due. Annual tax bills in Loudoun County are typically mailed out in late April and then again in late October.

As is common with residential property in many areas, tax payments might be covered through your home’s escrow account.

How Your Loudoun County Property Tax Works

Value assessment is the first part of the annual property tax cycle in Loudoun County. Assessors typically measure property values every two to four years. Under Virginia state law, cities need to do a new value assessment every two years. At the county level, Loudoun County assessors are required to update values every four years.

What exactly is reassessment? Reassessment measures a property’s fair market value. This is the price that the home would hypothetically sell for in a normal fair market. But fair market value isn’t necessarily the amount paid for a property. The home’s fair market value combines with its property tax rate to determine the property’s tax bill for the year.

When assessors set market value, they look at a range of information. This often includes sales information from previous years that can vary by property. Assessors might measure factors like the home’s age, size, condition and location within Loudoun County. Assessors then create a ratio of assessed values compared with selling prices.

Real estate assessment notices go beyond assessed value information following state law changes in recent years. They now include the amount of taxes due in past years for reference.

It’s common for your home’s assessed value to change from year to year. There are several different factors that can lead to changes in assessed value. Common situations that could lead to value changes are excess damage and home construction. For example, placing an addition on the home could lead to a value increase while severe damage or destruction could cause your home’s value to plummet from the previous year.
