Taxes & Insurance in Herndon
Herndon residents pay Fairfax County's real estate tax rate and the same NVTA-region 6.0% combined sales tax documented elsewhere in this dataset, on top of Virginia's statewide near-flat 5.75% income tax -- with no Herndon-specific income or property tax layer beyond standard county and town rates.

Herndon's combined 2026 sales tax rate is 6.0%: 4.3% Virginia state, 1.0% Fairfax County local, and 0.7% Northern Virginia Transportation Authority (NVTA) regional rate (Avalara, retrieved 2026-08-24) -- the same structure documented for Reston and other Fairfax County markets in this dataset.
Virginia's graduated-but-functionally-near-flat income tax
Virginia taxes income on a four-bracket schedule (2% on the first $3,000, 3% on $3,001-$5,000, 5% on $5,001-$17,000, 5.75% above $17,000) that functions as a near-flat 5.75% tax for most working filers, since the top bracket begins so low. Social Security is fully exempt at any age; the age-65 deduction (up to $12,000) phases out above $50,000 (single) / $75,000 (MFJ) federal AGI -- a statewide structure, not Herndon-specific.
No dedicated homeowners-insurance or hazard-cost data specific to Herndon this session
This research pass did not independently verify a Herndon-specific homeowners insurance premium figure; Herndon's real, documented hazard exposure is inland Sugarland Run flooding in the Fox Mill and Franklin Farm areas during heavy storms (see the climate topic page), not hurricane or coastal storm risk, which should factor into flood-insurance decisions for those specific areas.
