How Property Tax Works

Loudoun County, Virginia operates a comprehensive property tax system that serves as the primary funding source for essential county services including schools, public safety, transportation, and parks. The county assesses real property annually at fair market value, with taxes calculated based on a rate per $100 of assessed value. For fiscal year 2025, the base real property tax rate is $0.865 per $100 of assessed value, though actual rates vary by location within the county due to special taxing districts and municipal boundaries.

Property owners should be aware that Loudoun County contains multiple jurisdictions and special districts that can affect total tax liability. Towns within the county may levy additional municipal taxes, and certain areas may be subject to special district assessments for services like transportation or community development. The county also offers several tax credit programs that can reduce your tax bill, but most require annual application and are not automatically applied. Understanding these variations and available credits is essential for accurately estimating your property tax obligation.

Section 4

Supplemental Tax Bills

Supplemental taxes are additional property tax bills issued when there are changes to property ownership, new construction completion, or property improvements during the tax year. These taxes are prorated based on the number of months remaining in the fiscal year from when the change becomes effective. Loudoun County issues supplemental personal property tax bills with a due date of December 5 for vehicles and other personal property acquired or moved into the county during the tax year.

For real property, supplemental taxes commonly occur when new construction is completed and receives a certificate of occupancy, when property undergoes major improvements that increase assessed value, or when errors in the original assessment are corrected. The supplemental tax amount is calculated by applying the current tax rate to the increased assessed value, then prorating for the remaining months in the fiscal year. For example, if a $100,000 home addition is completed in January with 5 months remaining in the fiscal year, the supplemental tax would be approximately $361 ($100,000 × $0.865 ÷ 100 × 5 ÷ 12).

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for Loudoun County properties, collecting monthly payments as part of your mortgage payment to cover annual property tax bills. The lender analyzes your previous year's tax bill and divides by 12 to determine monthly escrow payments, often adding a cushion for potential tax increases. Property taxes in Loudoun County are due December 5 annually, and lenders typically pay the bill directly to the county on your behalf.

Property owners should verify their lender has the correct tax information, especially after refinancing or when moving from a different jurisdiction. The Loudoun County Treasurer's Office maintains current tax records and payment information at https://www.loudoun.gov/652/Treasurer. If you pay taxes independently without escrow, you can make payments online, by mail, or in person. Late payments incur penalties and interest charges, so ensure your lender pays timely or mark December 5 on your calendar for direct payments.
