Government

Collin County, like all 254 counties in Texas, is considered an extension of state government. The biggest focus of county government is judicial (civil and criminal justice, adult and juvenile probation), human services, law enforcement and jail services.

The county is also responsible for road and bridge maintenance in unincorporated areas, maintaining public records, collecting property taxes, issuing vehicle registrations and transfers, registering voters, conducting elections, and providing health and social services to indigent county residents.

With an estimated 80 people moving into Collin County each day, the county's population topped 1,000,000 residents in 2018 -- the 2020 U.S. Census puts us at 1,064,465 -- and county leaders are continually working on expanding our infrastructure to stay ahead of this growth.

The county tax rate is currently $0.149343 per $100 of assessed value. This is a rate reduction from 2022. In fact, the county property tax rate has not increased in 30 years. In 2008, Commissioners Court approved a 5-percent homestead exemption. In addition, Collin County's bond rating has maintained an AAA status since 2000 and is one of only four Texas counties to have this exceptional rating.

The county courthouse, which opened in the fall of 2007, is located in the county seat of McKinney, and houses the district courts, district attorney's office, law library, district clerk and additional services. The facility was approved by voters through a bond election in 2003, with an expansion approved in the 2007 bond election, which allowed the county courts at law to move into the courthouse in September 2012. In addition to the courthouse, there are more than a dozen county facilities that serve the public. Administrative offices are located in McKinney, as is the justice center, jail, public works, animal services and health care services.
