Learn moreSales tax: the statewide floor, not the NoVA regional rate
Warrenton's combined 2026 sales tax rate is 5.3% (4.3% state + 1.0% mandatory local) -- Fauquier County is not one of the Northern Virginia localities subject to the region's additional 0.7% transportation tax, so Warrenton's rate runs below Manassas, Fairfax, or Loudoun's 6.0% combined rate documented elsewhere in this project.
Virginia's graduated income tax, restated at the local level
Virginia taxes income at 2% on the first $3,000, 3% on $3,001-$5,000, 5% on $5,001-$17,000, and 5.75% above $17,000 -- functioning as a near-flat 5.75% tax for most working filers statewide, not a Warrenton-specific rate. Social Security is fully exempt at any age; the age-65 deduction (up to $12,000) phases out above $50,000 (single) / $75,000 (joint) federal AGI.
Property tax: a disclosed gap at the Fauquier-specific level
Virginia's statewide average effective property tax rate is 0.78% (Tax Foundation, 2026) -- this research pass did not independently confirm a Fauquier-County-specific rate, disclosed honestly as a gap rather than estimated from the statewide figure alone.
A real, recent flood hazard with direct insurance implications
The July 16, 2025 flash flood that caused $109,250 in Warrenton town-property damage reportedly left many affected residents and businesses without insurance or flood coverage -- a real, disclosed reminder to confirm current flood-zone status and flood-insurance coverage for any specific address, particularly near the Warrenton Reservoir and Blackwell Road corridor.
Key takeaways
- Warrenton's combined sales tax is 5.3% -- Virginia's statewide floor, below the 6.0% NoVA-regional rate that applies to Manassas, Fairfax, and Loudoun elsewhere in this project.
- Virginia's graduated income tax functions as a near-flat 5.75% for most working filers; Social Security is fully exempt and a $12,000 age-65 deduction phases out above $50K single/$75K joint AGI.
