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 Dallam County Appraisal District.
Effective rate
no single countywide effective rate; official CAD information lists separate taxing-unit rates.
Statement mailing
For the 2026 tax year, Texas Tax Code §31.01 requires the tax bill by October 1, 2026 or as soon thereafter as practicable; the Texas Comptroller says tax bills generally start mailing in October. No county-specific 2026 mailing date was published by the official source reviewed.
Payment deadline
2026 property taxes are due upon receipt and generally must be paid before February 1, 2027 (January 31, 2027 is the usual payment date); if a statutory deadline falls on a weekend, Texas Tax Code §1.06 postpones the act to the next regular business day. The local bill or tax office controls the posted delinquency date.
Valuation protest
May 15, 2026, or the 30th day after the appraisal district mails the 2026 Notice of Appraised Value, whichever is later, under Texas Tax Code §41.44; no different county-specific 2026 deadline was published by the official source reviewed.
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.
