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 Ascension Parish Assessor's Office.
Effective rate
millage varies by district and location; the official estimator's 11.5% figure is illustrative, not a single 2026 effective rate.
Statement mailing
official sources state bills are sent in the latter part of the year but do not publish an exact 2026 mailing date.
Payment deadline
December 31, 2026; the assessor and sheriff state annual parish bills are due December 31.
Valuation protest
September 10, 2026 by 5:00 p.m.; 2026 Open Book period is August 17-31, with Board of Review hearing September 17.
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.
