At their regular meeting on August 25, 2025, the Cooper I.S.D. Board of Trustees voted to adopt a tax rate of $0.9175 for the coming year, to maintain the lowest tax rate in more than 25 years.

This year's tax levy to fund maintenance and operations expenditures does not exceed last year's maintenance and operations tax levy. Ultimately, Cooper ISD is funded according to the number of students in attendance for the school year. Any gain in local tax collections is automatically offset by a subsequent reduction in state aid received.

The total Cooper ISD 2025-2026 tax rate includes $.7575 for the daily maintenance and operations of the district and $0.16 for payment of interest and sinking debts.
