Those who filed an “over 65” exemption, a disability or disabled veteran exemption or agriculture exemption could also get money back.

Wright says a “systemic problem” is responsible for people not getting their exemptions.

“The data belong to Tarrant Appraisal District,” said Wright.  “I don’t want to throw anyone under the bus but its their data and I would have liked to receive the exemptions a lot sooner.”
