Arizona Senate Bill 289 Adjusts Utility Credits and Rate Caps for Tucson Households
Tucson residents who receive utility service from providers regulated by the Arizona Corporation Commission may qualify for new annual credits and face limits on future rate increases under the legislation.
How we reported this
Arizona Senate Bill 289, the Household Budget Protection Act, took effect after passage in June and expands state tax credits applied to residential utility accounts while imposing annual caps on rate increases by regulated providers in Pima County.
The legislation followed review of consumption reports filed with the Arizona Corporation Commission. Those filings showed more than 250,000 residential accounts in the Tucson metropolitan area, many held by households that also claim the existing earned income tax credit on state returns.
Direct Changes to Monthly and Annual Costs
Qualifying households will receive an annual credit applied directly to their Tucson Electric Power or comparable utility account. The credit amount is determined by household size, income reported on the prior year state tax return, and the number of months the account was active within Pima County.
A single adult living in the 85705 zip code who meets income limits can expect the credit to offset a portion of summer electric charges. Families with school-age children enrolled in the Tucson Unified School District may receive a larger credit when they file their 2026 state returns next year.
The enrolled bill directs funds from a dedicated line item in the state general fund, with the initial allocation listed in the fiscal year 2027 budget papers approved by the Joint Legislative Budget Committee.
Applications open through the Arizona Department of Revenue online portal in October. Applicants must submit proof of Pima County residency and their most recent utility statement. The department will issue credits by direct account credit rather than paper checks.
Implementation begins with the first credits issued in February 2027. The government says the policy will reduce pressure on monthly budgets for those meeting the income criteria, with subsequent rate adjustments reviewed annually by the Arizona Corporation Commission.
