What's Changing?
Due to recent legislative changes, portions of the Property Tax Deferral Program administration will shift back to the counties beginning in the 2026 program year. County treasurers and assessors will be responsible for disseminating, accepting, reviewing, and recording applications and assisting homeowners with the application process.
The program will continue to serve senior homeowners (ages 65+) and active military service members. The tax growth category has been eliminated by state law and is no longer available for new applications.
