Upton County, Texas property-tax payment and appeal deadlines
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The reviewed record below separates published figures from items that still require confirmation with Upton County Appraisal District.
Rate context
Confirmno single verified 2026 countywide effective rate; Texas property tax rates are set separately by the county, cities, school districts, and other taxing units.
Statement mailing
PublishedOctober 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 mailing date.
Payment deadline
Published2026 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; installment and local statutory exceptions may apply.
Valuation protest

Do not assume a grace period.
The reviewed 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 a published payment deadline as a hard operational date and retain your receipt or confirmation number.
From assessment to collection
01Valuation 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.
02Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
03Payment 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.
