Corporate Tax Cut Savings Lead APS to Request Decrease in Customer Bills


PHOENIX – APS has requested the Arizona Corporation Commission approve a $119 million bill reduction for customers, based on federal corporate tax cuts, effective February 1, 2018.  

If approved, the $119 million decrease will offset the $95 million revenue increase that resulted from APS’s last rate review. The savings of $0.004258/kWh will be passed directly to customers through the Tax Expense Adjustor Mechanism (TEAM), a new adjustor mechanism that was included in the company’s rate review, and customer savings will vary with actual energy usage. APS customers would receive the credit on their monthly bill.

Authorized adjustors reset each year and will impact customer bills throughout 2018. Bill impact of adjustors will vary with actual energy usage and service plan. APS anticipates additional tax cut savings will be available at a later date once the full impact of the new law is realized. For additional information on how to reduce energy usage, customers can visit
