Cameron 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 Cameron Appraisal District.
Rate context
ConfirmCameron CAD and the tax office identify multiple taxing entities; official local sources reviewed do not publish one countywide effective rate.
Statement mailing
Published2026 appraisal notices were scheduled to begin mailing April 6, 2026; tax bills are mailed by October 1, 2026 or as soon thereafter as practicable under Texas Tax Code §31.01(a).
Payment deadline
Published2026 property taxes are due upon receipt; January 31, 2027 is generally the last day to pay without penalty and interest, with delinquency beginning February 1, 2027 if the bill was mailed by January 10, 2027. A later-mailed bill receives a postponed delinquency date under Texas Tax Code §§31.01 and 31.04, as shown on the bill.
Valuation protest
PublishedMay 15, 2026, or 30 days after the date printed on the 2026 Notice of Appraised Value, whichever is later; Cameron CAD scheduled 2026 formal ARB hearings to begin May 18, 2026.
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.
