Historical Property Tax Abatements

The Collin County Commissioners Court allows county property tax abatements to qualifying historical properties. The Collin County Historical Commission is tasked with the authority to accept applications for historical tax abatements, inspect the properties to determine eligibility for an abatement, and to recommend to the Commissioners Court which properties should receive this benefit.

The tax abatement guidelines have changed for 2017. Please download the Tax Abatement Application Packet  for more information. Remember that even if you've qualified for a county abatement in the past, you may not qualify under the new guidelines. So please refer to the packet for new important changes to this program.
