Navigating Fairfax County property tax requirements involves understanding real estate assessments, tangible personal property levies, payment schedules, and available tax relief programs. Property taxes in Fairfax County, Virginia, are administered locally by the Department of Tax Administration (DTA), with revenues funding public education, infrastructure, public safety, and community services.
Understanding the Fairfax County Property Tax Framework
The Fairfax County property tax system relies on two primary categories of taxation: real estate property tax and personal property tax. Every parcel of land, residential home, commercial building, and registered vehicle within the county boundaries is subject to assessment and taxation based on fair market value.
Real estate taxes are levied per $100 of assessed value. The Board of Supervisors establishes the real estate tax rate annually during the adoption of the county budget. Personal property taxes apply to vehicles, boats, and business equipment, utilizing specialized depreciation schedules established by state code and county ordinances.
Understanding how property is valued requires examining the assessment process managed by the county supervisor of assessments. Property values are adjusted annually to reflect prevailing market conditions, meaning that changes in real estate market activity directly influence tax liabilities regardless of whether the tax rate remains stable or fluctuates.
2026 Fairfax County Property Tax Rates and Assessment Valuations
Property assessments in Fairfax County reflect 100% of fair market value as of January 1 of the tax year. The Department of Tax Administration uses comparable sales data, income and expense data for commercial properties, and cost approach methods to determine these valuations.
| Tax Category | 2026 Rate Structure | Assessment Basis | Billing Frequency |
|---|---|---|---|
| Residential Real Estate | Variable per $100 of assessed value | 100% of Fair Market Value | Semi-Annual (July / December) |
| Commercial Real Estate | Variable per $100 of assessed value | 100% of Fair Market Value | Semi-Annual (July / December) |
| Personal Property (Vehicles) | Standardized rates per $100 value | Clean trade-in value / NADA guidelines | Annual (Due October 5) |
| Business Personal Property | Depreciated equipment value | Original cost minus depreciation | Annual (Due October 5) |
Homeowners receive assessment notices in early spring. Property owners who believe their assessment exceeds current market value have the legal right to appeal the valuation through administrative review, the Board of Equalization, or the Circuit Court.
Important Payment Deadlines and Schedules
Timely payment of Fairfax County property taxes prevents the accumulation of statutory penalties and interest charges. Real estate taxes are billed semi-annually, while personal property taxes operate on an annual billing cycle.

Failure to remit payment by the established deadlines results in a mandatory 10% penalty or statutory late fee, followed by interest accruing at a rate specified by Virginia law until the balance is paid in full.
