Summary answer: Prince William County's real estate tax rate for FY2026 is $0.906 per $100 of assessed value (combined rate roughly $0.98 with fire, rescue, and pest management levies). On a $500,000 Dale City home, that works out to roughly $4,530–$4,900 per year, or about $378–$408 per month — notably lower than Fairfax, Arlington, or Alexandria.

How your bill is actually calculated
Prince William assesses property at 100% of fair market value, with two payment installments (July 15 and December 5). Your bill is your home's assessed value multiplied by the current rate, plus the fire/rescue and pest management levies.
Why this matters for your monthly budget
- Your lender includes this in your monthly payment — rolled into escrow along with principal, interest, and insurance
- It's a real advantage for Dale City affordability — lower taxes on top of a lower purchase price compound your savings versus buying closer to DC
- HOA fees, if applicable, count separately against your DTI
Can you appeal your assessment?
Yes — Prince William County allows homeowners to formally appeal if they believe their assessed value exceeds fair market value.
