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 Merrick County Assessor / Merrick County Treasurer.
Effective rate
no single countywide effective rate verified; Nebraska tax rates are set by the consolidated local tax district and vary by taxing subdivisions.
Statement mailing
Around December 1, 2026; Merrick County Treasurer FAQ states tax notices are mailed around December 1.
Payment deadline
2026 Nebraska real-property taxes are due December 31, 2026; the first half becomes delinquent May 1, 2027 and the second half becomes delinquent September 1, 2027; 14% statutory delinquent interest applies. Taxes are paid to the county treasurer.
Valuation protest
June 1–June 30, 2026; Nebraska Department of Revenue guidance requires a real-property valuation protest to be filed on or before Tuesday, June 30, 2026 with the county board of equalization, generally through the county clerk, using Form 422 or 422A.
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.
