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 Grant Parish Tax Assessor.
Effective rate
the official assessor gives a 170-mill parish-tax illustration, but actual millage varies by district and no single 2026 effective rate was published.
Statement mailing
no specific 2026 mailing date was published by the reviewed official assessor or sheriff source.
Payment deadline
December 31, 2026; Louisiana parish property taxes are due by December 31 of the tax year and become delinquent after that date, with applicable interest and penalties.
Valuation protest
August 15-September 15, 2026 statutory public-exposure window; the exact parish 15-day open-books dates and Board of Review hearing date were not published by the reviewed official parish source.
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.
