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 Weston County Assessor; Weston County Treasurer (property-tax collection).
Effective rate
no single countywide effective property-tax rate is published; mill levies vary by Weston County tax district and taxing entity.
Statement mailing
October 10, 2026; Weston County's assessment calendar states the County Treasurer sends tax bills on October 10.
Payment deadline
For 2026 property taxes: billed and due September 1, 2026; first half must be postmarked by November 10, 2026 and becomes delinquent November 11; second half must be postmarked by May 10, 2027 and becomes delinquent May 11; full payment is due December 31, 2026.
Valuation protest
Within 30 days of the 2026 assessment schedule mail date; Weston County states schedules are mailed by the fourth Monday in April (April 27, 2026) and written objections are due within 30 days.
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.
