Property Tax Protest
You Have the Right to Protest Your Property's Appraised Value
If your Johnson County appraisal seems too high, you can formally protest it — and many property owners do so successfully each year.
Every year, the Central Appraisal District of Johnson County mails notices showing each property's appraised value. If you believe the value is too high, you can file a protest. The general deadline is May 15 or 30 days after the appraisal district mails your notice, whichever is later — the clock starts on the mailing date, not the date you receive it.
You can protest informally first by contacting the appraisal district and providing evidence — a recent appraisal, comparable sales, or proof of condition issues. If that does not resolve it, you can go before the Appraisal Review Board (ARB). Visit johnsoncad.com or comptroller.texas.gov for current deadlines and forms.
