Issues We're Facing

Water Conservation Rebate Tax Parity

Taxing water conservation rebates impedes efforts to encourage the adoption of water efficiency measures.

Every drop of water counts in a desert. The Phoenix metro area has enough water to support a growing economy for the next 100 years and beyond, but waste is not an option. For this reason, many of the Valley’s cities are on the forefront of helping citizens and businesses use their water wisely. 

Many communities offer rebates to help customers offset the cost of making their homes and yards more water efficient. Rebate programs help accelerate the uptake of water efficiency measures, such as upgrading fixtures or converting to desert-adapted landscapes, by reducing the cost to the consumer. This is increasingly important to cities working to reduce water demand to offset the impacts of ongoing drought and climate change and to stretch water supplies to meet future needs.  

Unfortunately, homeowners are often surprised to learn they must pay federal income tax for doing their part to use less water. The Internal Revenue Service taxes water conservation rebate checks of $600 or more as “miscellaneous income.” As the number and size of water conservation rebates have increased, so has the number of homeowners receiving an IRS Form 1099 reporting miscellaneous income of $600. Cities and utilities, particularly those in western states, are concerned that continuing to tax water conservation rebates will discourage their customers from using them and limit an important conservation tool.

As rebates to encourage homeowners to convert grass to low water use landscape have increased in price and popularity, more residents have been surprised to find they have to pay income tax.

In January 2016, the Internal Revenue Service and the Treasury Department confirmed that congressional action is necessary to exempt these rebates from federal income tax. Congress exempted energy conservation rebates from federal income tax in 1992. Cities, utilities, and conservation groups are coming together to ask Congress for a solution that gives water rebates the same status as energy rebates or “tax parity.” The Treasury Department has listed this change as a desired amendment in its “Greenbook” budget request, and the Congressional Joint Tax Committee determined that the impact on the federal budget would be negligible.  

Bills have been introduced with provisions to address this issue since 2016, including this year, none have been successful.

The Coalition to Promote Water Conservation (CPWC), an ad hoc group of large water agencies and organizations from across the country, is coordinating tax parity advocacy efforts at a national level. CPWC includes the Alliance for Water Efficiency, the American Water Works Association, and the Western Urban Water Coalition, among others.

Current Efforts

In 2016, the AMWUA Board of Directors passed a resolution supporting the exemption of water conservation rebates from taxes and directed staff to actively advocate for resolution of this issue.

Through the Alliance for Water Efficiency, AMWUA staff coordinates local efforts with those occurring at a national level. AMWUA staff is keeping Arizona providers and water organizations apprised of developments, including when and how to best take action. 

The Northern Arizona Municipal Water Users Association and the Southern Arizona Water Users Association also have adopted resolutions and have sent letters to Arizona’s congressional delegation.

A recent study by the Alliance for Water Efficiency found that replacing inefficient toilets across five states in the western U.S. could save up to 170 billion gallons of water per year.

What you can do

Ongoing Support Needed:

Cities, towns, and organizations are encouraged to adopt resolutions. Copies should be sent to your representatives as well as to the Alliance for Water Efficiency  to share with the national coalition.  

A short call, email or tweet to your congressional representative  will help build momentum.
