TX HB4580

Creates a property tax exemption for all real and personal property owned by nonprofit corporations in counties with a population of 3.3 million or more (currently only Harris County qualifies)

Qualifying nonprofits must be organized exclusively for charitable, educational, and scientific purposes and use the property to promote agriculture, support youth, and provide educational support in the community

Allows incidental use of the property for other purposes without losing the exemption, as long as revenue from that use benefits the charitable organization's beneficiaries

Excludes from the exemption any property interests held by for-profit lessees of the nonprofit's property

Once approved, the exemption does not need to be reclaimed annually and remains in effect until ownership changes or qualification status changes; takes effect January 1, 2026
