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 Brown County Appraisal District.
Effective rate
Texas property taxes are set by multiple local taxing units; official county/CAD sources reviewed do not publish one countywide effective rate.
Statement mailing
official local sources reviewed do not publish a specific 2026 tax-bill mailing date.
Payment deadline
2026 property taxes are generally due upon receipt; if the bill is mailed by January 10, 2027, taxes may be paid without delinquency through January 31, 2027 and become delinquent February 1, 2027, subject to Texas Tax Code §§31.01 and 31.02 and next-business-day rules.
Valuation protest
May 15, 2026, or 30 days after the appraisal district mails the Notice of Appraised Value, whichever is later, under Texas Tax Code §41.44 and official Texas Comptroller guidance.
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.
