Real Estate Tax Assessments and Payment Procedures for 2026

Real estate taxes represent the largest share of local revenue for Fairfax County. The assessment process is conducted annually by the DTA, which determines the fair market value of all land, buildings, and improvements as of January 1 of the tax year.

Property owners receive their official assessment notices in the mail early in the year, detailing the current market valuation compared to the previous year. If an owner believes the assessment exceeds current fair market value, an administrative appeal can be filed through the DTA, followed by an appeal to the Board of Equalization.

Personal Property Tax Framework: Vehicles, Boats, and Business Assets

Unlike many other states, Virginia levies a personal property tax on tangible property owned by residents and businesses. This includes passenger vehicles, trucks, trailers, motor homes, boats, and aircraft. For businesses, furniture, fixtures, and computer equipment used in operations are also subject to local taxation.

The tax rate for personal property in Fairfax County is traditionally set at $4.57 per $100 of assessed value for standard vehicles, though specific classifications (such as vehicles modified for individuals with disabilities or qualified alternative-fuel vehicles) may qualify for tax relief or reduced rates.

Managing Personal Property via the Portal

• Vehicle Registration: Residents must register any vehicle garaged in the county within 60 days of purchase or relocation to avoid late-filing penalties.
• Assessment Valuation: Values are calculated using recognized pricing guides (such as the J.D. Power / NADA official guides) as of January 1, 2026.
• Proration Rules: Fairfax County operates on a prorated system for personal property. If a vehicle is purchased, sold, moved into, or moved out of the county during the year, the tax liability is adjusted based on the number of months the vehicle was sited in the jurisdiction.
