Texas, State-Wide

Not only is it legal to collect rainwater in Texas, the State also recognizes the importance of rainwater and fully supports rainwater harvesting as a sustainable solution. To encourage rainwater harvesting, all rainwater equipment, supplies are tax-free under Texas Tax Code Section 151.355 (Read More). And yes! This means the installation of your rainwater system, no matter the size, is free from sales tax.

Furthermore, under Texas Tax Code 11.32, property owners “may exempt from taxation part or all of the assessed value of property on which approved water conservation initiatives [including rainwater harvesting]….have been implemented.”
