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 Shelby County Appraisal District.
Effective rate
no single countywide effective 2026 rate; Shelby County publishes rates by taxing entity.
Statement mailing
October 1, 2026 or as soon thereafter as practicable under Texas Tax Code §31.01(a); the official local sources reviewed did not publish a more specific 2026 tax-bill mailing date.
Payment deadline
2026 Texas property taxes are due upon receipt; taxes are generally delinquent February 1, 2027. Because January 31, 2027 falls on Sunday, timely payment is due Monday, February 1, 2027 and delinquency begins Tuesday, February 2, 2027 under Texas Tax Code §§1.06 and 31.02.
Valuation protest
June 8, 2026, or 30 days after the 2026 Notice of Appraised Value was mailed, whichever is later (Shelby CAD 2026 protest-process notice).
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.
