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 Arlington County Department of Real Estate Assessments / Treasurer’s Office.
Effective rate
$1.053 per $100 assessed value, adopted for calendar year 2026; an additional $0.125 commercial/industrial transportation tax may apply.
Statement mailing
2026 assessment notices mailed beginning January 20, 2026; real-estate tax bills are issued in two installments.
Payment deadline
June 15, 2026 and October 5, 2026 installments; stormwater fee is billed with real estate tax.
Valuation protest
the 2026 assessment notice and Department of Real Estate Assessments appeal instructions control the exact review/BOE deadline; no single deadline was verified in the official page text retrieved.
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.
