What’s Actually Changing in 2026 — The Arizona OBBBA Update

The narrative of expiring tax cuts is over. OBBBA has locked in major benefits and added new ones. Here’s what Arizona residents need to know.

Federal Standard Deduction is PERMANENT

The higher federal standard deduction is now a permanent feature of the tax code, providing stability and simplifying tax filing for millions.
Arizona Impact

While Arizona has its own standard deduction, the permanent, higher federal deduction is a significant benefit. It ensures that fewer Arizonans, especially homeowners in high-cost-of-living areas like Scottsdale and Chandler, will be forced into the complexity of itemizing deductions. This provides a stable foundation for tax planning.

Lower Federal Tax Brackets are PERMANENT

The lower individual income tax rates from the TCJA are also here to stay, preventing a sudden tax hike for Arizona families and professionals.

Arizona Impact

This is excellent news for Arizona’s diverse workforce, including tech professionals in the Phoenix-Scottsdale corridor, healthcare workers in Mesa, and the state’s large construction and trades sector. Families earning between $, and $, will avoid the significant tax increases they were previously expecting.

The QBI Deduction is PERMANENT and ENHANCED

This is the most critical update for Arizona’s business community. The 20% Qualified Business Income (QBI) Deduction is not expiring. OBBBA has made it a permanent part of the tax code and even improved it.

Arizona Impact:
This is a massive win for the state’s thriving small business ecosystem. From realtors in the booming Phoenix market to STR owners in Sedona and Flagstaff, the permanent QBI deduction provides tens of thousands of dollars in annual tax savings, fueling further investment and growth.

New Federal Tax Breaks for Arizona Residents

OBBBA also introduced several new deductions that will directly benefit many in Arizona:

Arizona-Specific Considerations for 2026

Arizona’s Flat Tax and Federal Conformity

Arizona boasts a competitive 2.5% flat state income tax. While this rate remains unchanged, your state tax bill is calculated based on your federal Adjusted Gross Income (AGI). Because OBBBA makes permanent many federal deductions, it helps keep your AGI lower, which in turn reduces your state tax liability. Arizona generally conforms to the Internal Revenue Code, meaning many of these federal benefits will flow through to your state return.

Arizona’s Booming Real Estate Market

For property owners in hot markets like Phoenix, Scottsdale, and Flagstaff, OBBBA brings welcome news. The 100% bonus depreciation for qualified property is now permanent. This allows real estate investors to immediately write off the cost of certain assets, making strategies like cost segregation incredibly powerful. With Arizona’s real estate market poised for continued growth in 2026, timing property sales and managing capital gains exposure remains a critical planning point.

STR Owners in Scottsdale, Sedona, and Flagstaff

As a top STR market in the U.S., Arizona investors benefit greatly from OBBBA. The permanence of the QBI deduction and 100% bonus depreciation provides a stable foundation for profitability. However, the IRS continues to focus on material participation and proper documentation. Proactive planning is essential to ensure you continue to qualify for these valuable deductions.
Arizona = One of the Hottest STR Markets in the U.S.
