Lewisville, Denton County, Texas

Property Tax Rate

1.72% of market value a year, before exemptions

The Texas Comptroller's 2025 adopted rates, per $100 of value: county $0.1859, city $0.4190, Lewisville ISD $1.1178. On a home worth $400,000 that is about $6,891 a year.

Texas appraisal districts value a home at 100% of market value, so these rates apply to about the price. The seller's cap on yearly increases (10% for a homestead) ends with a sale, so the first bill after buying is on about the price and can be well above the seller's. A buyer who lives in the home can claim a school homestead exemption of $140,000 off the school district's taxable value, which lowers the school part of the bill; some counties and cities add exemptions of their own.

Not in this figure: college, hospital, flood-control and emergency-services districts, and a municipal utility district (MUD) if the home is in one, which can add $0.50 to $1.00 per $100. Lewisville can lie in more than one school district; the school rate above is for the district at the center of the city, so check the district of a specific address. The rates are the latest the Comptroller has published (2025); rates adopted for the current year can differ. Exemption and cap figures were last reviewed November 3, 2026.
