Over 65 Homestead Exemption
For residents 65 and older, your school district tax bill should never increase, even if their property values increase (excluding property improvements) as long as an approved Homestead and Over 65 Exemption application is on file with the Collin County Appraisal District.
Regardless of election results, the school district taxes should never go above the tax ceiling (the amount you paid in the year you qualified for the age 65 exemption) for someone with the Over 65 Exemption on file.
This exemption is not automatic. You must apply. Plano ISD and all Collin County school districts allow an Over 65 Exemption. However, all other taxing units have the option of allowing the Over 65 Exemption.
