Greywater and Rainwater Harvesting Tax Credits in Arizona Effective January 1, 2007, Arizona taxpayers who install a “water conservation system” (defined as a system to collect rainwater or residential greywater) in their residence may take a one-time tax credit of 25% of the cost of the system (up to a maximum of $1,000). Builders are eligible for an income tax credit of up to $200 per residence unit constructed with a water conservation system installed.

Note that a misinterpretation of the tax credit used to only give the credit to greywater harvesting systems, but thanks to efforts by Rep. Steve Farley the tax credit can now also be used for rainwater harvesting systems, and it is retroactive to January 1, 2007. So, anyone who has purchased water harvesting systems from that point onward will get AZ tax credits until the annual amount allotted to the credit has ben filled.
