2026 fiscal calendar
Know the tax date before it becomes a penalty date.
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The verified record below separates published figures from dates that require confirmation with Prince William County Real Estate Assessments Office; Tax Administration/Treasurer collects taxes.
Effective rate
$0.865 per $100 base real-estate rate for 2026, plus $0.0700 countywide Fire and Rescue levy and $0.0020 Mosquito and Forest Pest Management levy where applicable; service-district levies may also apply.
Statement mailing
the official 2026 calendar states assessment notices are mailed in March but does not publish a routine tax-bill mailing date.
Payment deadline
July 15, 2026 (first-half real-estate taxes) and December 7, 2026 (second-half real-estate taxes).
Valuation protest
June 1, 2026 for the administrative assessment appeal; July 1, 2026 for the Board of Equalization appeal.
Critical payment warning
Do not assume a grace period.
The verified county record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat the published payment deadline as a hard operational date and retain your receipt or confirmation number.
Read the calendar in order
From assessment to collection
1. Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
2. Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
3. Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
