Austin, Texas Offers Rebates for Rainwater Harvesting Systems



Ready to Store Rainwater for Later Beneficial Use


Rainwater harvesting is one part of the Texas State Water Plan by the TWDB (link) as an alternative water source. Rainwater harvesting helps to alleviate the strain on utility water as well as help managing stormwater, by putting it to later use. Since rainwater collection is a solution for the state as well as on many local levels, rebates and tax incentives are very common in Texas. The Texas Tax Code also exempts rainwater harvesting equipment and supplies from state sales tax (Texas Tax Code §151.355).


View Section 151.355 of the Texas Tax Code (link). In order to have your system components be sales-tax-free, you must fill out a Texas Tax Exemption Application Form 01-339 and give it to the supplier at the time of purchase.


In Austin, Texas the rebates available for equipment as well as the installation of a rainwater system for a home or business are up to $5,000 per qualifying site. For rainwater systems with water storage tanks with 500-gallon capacity and larger, the project must be pre-approved with the City of Austin to qualify for the rebate.

You must meet all of the eligibility requirements to be able to claim this rebate. The system needs to be installed, and the application submitted with an itemized, dated, paid-in-full receipt with the vendor contact information. Commercial rainwater systems need to also include an IRS W-9 form. The rebate checks take on average six to eight weeks to be mailed out.
