Summary answer: Reston's combined effective property tax rate runs roughly $1.22 per $100 of assessed value — Fairfax County's base rate of $1.1225, plus the Reston Service District levy ($0.021) and Reston Community Center levy ($0.047). On a $620,000 home (near Reston's median), that works out to roughly $7,500–$7,700 per year, or about $625–$640 per month.

Why this differs from other Fairfax cities
Unlike Centreville or Chantilly, Reston carries these additional special district levies that fund community-specific services — worth knowing, since it means your Reston tax bill runs somewhat higher than the base Fairfax County rate alone would suggest.
How your bill is actually calculated
Fairfax County assesses property at 100% of fair market value annually, with two payment installments (July 28 and December 5).
Why this matters for your monthly budget
- Your lender includes this in your monthly payment — rolled into escrow along with principal, interest, and insurance
- This is separate from Reston Association HOA dues — a mandatory additional cost most Reston properties carry
- Annual reassessments can shift your bill year to year
