Property taxes and special districts
A Texas home pays tax to several bodies at once: the county, usually a city, a school district and often special districts. Rates are per $100 of taxable value, as reported to the Texas Comptroller for 2025. Your bill depends on which of these overlap the lot, which a HouseDirt report works out for the exact address.
23 municipal utility districts (MUDs) and 30 water, utility, improvement and similar districts in all reported a 2025 tax rate in Collin County. The median MUD rate was $1.00 and the highest $1.20 per $100. A MUD or PID can add a large share to a tax bill; see how MUD and PID taxes work.
