Frequently Asked Questions
How do I protest my Collin County property tax assessment?
File a protest with CCAD by May 15, or within 30 days of receiving your Notice of Appraised Value. File online at collincad.org, by mail, or in person at 250 Eldorado Pkwy, McKinney. The informal meeting with a CCAD appraiser is the most productive step — Collin County's informal success rate is approximately 70 percent. If unresolved, the matter goes to an ARB hearing. Ownwell manages the entire process and only charges if you save.
What exemptions are available to Collin County homeowners after 2025 legislation?
The standard homestead exemption removes $140,000 from taxable value for school district taxes. Homeowners 65 or older or with qualifying disabilities receive an additional $60,000. The county applies a 20 percent reduction to the appraised value for homesteaded properties. The over-65 school tax freeze prevents school taxes from increasing. The Texas 10 percent annual appraisal cap limits annual increases regardless of market movement. File all exemptions at no cost with CCAD at 469-742-9200.
Where do I file probate in Collin County?
The six County Courts at Law at 2100 Bloomdale Road, McKinney, handle probate in Collin County. All probate cases must be filed electronically through eFile Texas. Texas allows independent administration for most estates, with minimal court involvement after initial approval. Small estates under $75,000 of personal property may use a Small Estate Affidavit. Contact the County Court at Law Clerks at 972-548-4320.
What senior services are available in Collin County?
The Collin County Area Agency on Aging (972-548-5522) serves residents 60 and older with home-delivered meals, transportation, caregiver support, SHIP Medicare counseling, and the Long-Term Care Ombudsman program. Texas STAR+PLUS Medicaid funds in-home and nursing care for qualifying seniors. The Property Tax Deferral program allows eligible seniors 65 or older to defer taxes until the property is sold, with 5 percent annual interest. Families in newer northern Collin County communities should plan ahead as senior care infrastructure may be more limited than in established areas.
