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 Dallas Central Appraisal District.
Effective rate
no single countywide effective rate; Dallas County has many taxing jurisdictions and rates vary by property location.
Statement mailing
The 2026 appraisal notices have been mailed; the 2026 tax-bill mailing date is otherwise governed by Texas Tax Code §31.01: October 1, 2026 or as soon thereafter as practicable.
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
June 11, 2026, according to DCAD's 2026 protest-process notice; the statutory rule remains May 15 or 30 days after the Notice of Appraised Value was mailed, whichever is later.
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.
