Co-sponsor HB 2511
Introduced · Arizona House · Co-sponsor
early ballot collection; limitations; repeal

Maddy summaryHB 2511 modifies Arizona's election laws to restrict ballot handling and strengthen signature requirements for early voting. It amends Section 16-513 to clarify that only voters, family members, household members, or caregivers may handle ballots, and Section 16-547 requires early ballots to include a signed mail affidavit with specific return instructions. Starting in 2026, voters must return ballots with their signature to a county recorder’s office, polling place, or by presenting ID at a polling place by 7:00 p.m. on election day. The bill also amends Section 16-1005 to increase penalties for improper ballot collection, making it a class 5 felony to collect ballots unlawfully or fail to turn them over to election officials. These changes directly affect voters, election officials, and anyone involved in ballot handling.

Primary HB 2491
Introduced · Arizona House · Lead sponsor
business income; corporate tax; allocation

Maddy summaryHB 2491 modifies Arizona's corporate tax calculation method for businesses operating across state lines. It changes how taxable income is apportioned between states, gradually shifting from a formula balancing property, payroll, and sales factors to using *only* the sales factor for most businesses starting in 2016 (through 2026). This directly affects corporations with operations in multiple states, as it increases the weight of sales activity within Arizona for tax purposes. The bill specifies different calculation formulas for various time periods, with the 2016-2026 period requiring businesses to use the sales factor alone to determine Arizona tax liability.

ESAs; parental notification; waived rights.

Maddy summaryHB 2704 requires Arizona's education department to provide parents with a clear notice detailing all legal rights they waive when enrolling their child in the state's Arizona Empowerment Scholarship Account (ESA) program. This notice must be included in application packets and posted on the department's website, ensuring parents understand the terms before enrollment. The bill does not change ESA funding or eligibility but adds this mandatory disclosure requirement to improve transparency. It directly affects parents and students participating in the ESA program, who must acknowledge these waived rights as part of the application process. The legislation focuses on informing families about program limitations without altering the existing ESA structure.

affordable housing; tax credits

Maddy summaryHB 2644 creates a new tax credit for Arizona taxpayers investing in affordable housing projects that qualify for federal low-income housing tax credits. It allows investors to claim credits against their insurance premium tax liability (not income tax), with a $10 million annual cap for projects meeting federal standards, administered by the Arizona Department of Housing. The credit is allocated based on project eligibility statements, can be shared among investors regardless of ownership stake, and expires after 2031. Taxpayers must submit documentation with their tax returns, and unused credits may be carried forward for up to five years. The bill requires annual reporting on housing impacts but does not change income tax rates or directly affect renters.

tax deed; sale; affordable housing

Maddy summaryHB 2714 amends Arizona's tax deed sale process to prioritize affordable housing development. It allows counties to sell property held by the state due to unpaid taxes directly to cities, counties, or housing authorities for low-income housing without requiring a public auction, provided a recorded agreement ensures affordability for at least 30 years. The bill also includes streamlined sales to contiguous property owners (for commercial, agricultural, or residential use) and homeowners' associations for common areas. These changes aim to facilitate affordable housing projects by removing auction barriers for eligible properties while maintaining standard procedures for other sales.

Primary HB 2141
Introduced · Arizona House · Lead sponsor
environmental permitting; requirements; burdened communities

Maddy summaryHB 2141 requires environmental impact reports and public hearings for new or expanded facilities (like power plants over 10MW, landfills, or waste treatment plants) located in low-income census tracts defined as areas in the bottom 33% for median household income. It mandates that permit applicants submit impact assessments 30 days before public hearings, which must include community input on health and environmental risks. The state environmental department must wait 60 days after hearings to approve permits and can deny them if cumulative health or environmental risks would be unreasonable for residents. This law directly affects companies seeking permits for large facilities in designated low-income areas, ensuring community input is considered before approvals.

data centers; TPT distribution; solar

Maddy summaryHB 2702 establishes Arizona's "Solar for All" program to provide funding, technical assistance, and workforce support for low-income households and disadvantaged communities to access solar energy. The program, administered by the governor's office of resiliency, allocates funds for solar installations on homes and multifamily housing in disadvantaged areas, prioritizing projects that deliver at least 20% annual electricity bill savings and include local hiring commitments. Eligible households must earn ≤80% of the area median income, and the program prohibits utilities from charging extra fees to participants. Funds come from legislative appropriations, TPT distributions, and private sources, with grantees required to report annual outcomes like savings, emissions reductions, and job creation.

employers; list; welfare recipients; commission

Maddy summaryHB 2735 requires Arizona's Industrial Commission and Department of Economic Security to publish annually, starting January 1, 2027, a list of the top 50 employers with the most employees receiving Medicaid or other public assistance. The list must include employer names, sizes, counts of employees and dependents on specific assistance programs, and data on public welfare costs - while excluding individual names for privacy. Employers offering health benefits must also report how many employees use public assistance. This mandates transparency about public assistance usage among large employers without disclosing confidential personal information.

team designations; biological sex; repeal

Maddy summaryHB 2392 repeals Section 15-120.02 of the Arizona Revised Statutes, which previously addressed team designations related to biological sex. The bill does not create new policy but removes an existing statutory provision. It is currently in early legislative stages, having passed its first two readings in the House on January 20-21, 2026. This is a procedural repeal without direct impact on current laws or individuals, as it eliminates a prior statute rather than altering current regulations. The bill’s specific content prior to repeal is not detailed in the provided text.

abortion; repeals.

Maddy summaryHB 2653 is a technical legislative bill that repeals specific Arizona statutes related to health care institution leasing (Sections 1-219, 13-3603.01, 13-3603.02, 13-3605, 15-115, 15-115.01, and 15-1630) and amends Section 15-1637. The bill directly affects nonprofit health care institutions operating under lease agreements with the Arizona Board of Regents, modifying provisions about property leasing, tax exemptions, bond issuance, and reporting requirements for these facilities. It does not address abortion access or policy; the title "abortion; repeals" appears to be an error, as the bill text contains no abortion-related provisions. The amendments clarify lease terms, financial reporting, and restrictions on acquiring additional health care properties.
