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 Logan County Auditor (Jack Reser) / Treasurer (Rhonda K. Stafford).
Effective rate
Logan County publishes tax rates by taxing district, not one countywide effective average.
Statement mailing
Second-half 2025 real-property/public-utility bills were mailed later than usual because of HB 186; the official Treasurer page does not publish an exact 2026 mailing date.
Payment deadline
2025 real-estate first half due February 11, 2026; second half originally due July 8, 2026 but extended to July 22, 2026 because of HB 186 Inflation Cap Credit implementation. 2026 manufactured-home installments use the same dates on the Treasurer FAQ.
Valuation protest
January 1–March 31, 2026 for tax year 2025 payable in 2026; Logan County Board of Revision complaints use DTE 1 and the statutory March 31 deadline.
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.
