Tax season is officially open in Arizona, but residents are being urged to hit pause on their state returns while a political fight at the Capitol plays out over how to handle recent federal tax changes. File your Arizona return too early, and you could be stuck redoing it later, which means extra paperwork and potential delays for refunds or key credits that matter to families and small businesses.
Capitol standoff could force filers to refile
The warning stems from the fact that Democratic Gov. Katie Hobbs and the Republican-controlled Legislature still have not nailed down “tax conformity” for the 2025 tax year, according to Axios. In plain English, they are fighting over how closely Arizona should mirror major federal tax changes. If lawmakers eventually pass something that does not line up with what is on this year’s state forms, some Arizonans could have to file amended returns.
What the revenue department is telling taxpayers
The Arizona Department of Revenue says individual state tax forms went out before the Legislature took action, which leaves taxpayers with a few choices: wait to file, request an extension, or go ahead and file now while assuming Arizona will adopt the federal changes, per the Arizona Department of Revenue. The agency also says anyone who is later required to amend an Arizona return will not be hit with penalties or interest as long as those amended filings are submitted by Oct. 15, 2027.
Hobbs' middle-class plan vs. GOP package
Hobbs has been pushing a narrower Middle Class Tax Cuts plan and signed an executive order telling the revenue department to draft forms that would increase the standard deduction, exempt tipped income and eligible overtime wages, and create a $6,000 deduction for people 65 and older, according to the Office of the Arizona Governor. The governor’s office and Democratic leaders say that approach would cost the state about $250 million, while Republican proposals would drain significantly more in the first year.
Republicans' bill, the veto, and the fuss
Republican lawmakers advanced a broader conformity bill that would more fully track last year’s federal tax package and, according to some legislative estimates, cut state revenue by hundreds of millions of dollars. Gov. Hobbs vetoed that GOP plan in mid-January, which is what triggered the current uncertainty, according to KJZZ. Republican leaders are pressing for a fast deal, arguing that immediate conformity is the only way to give taxpayers true clarity.
Federal changes that could reshape refunds
All of this is happening on top of sweeping federal tax changes from last year that already shift who comes out ahead this season. The standard deduction went up, new deductions were created for tips and parts of overtime pay, seniors get an additional deduction, and the child tax credit was increased, according to The Washington Post. Those moves change the math on federal returns and, depending on what Arizona ultimately decides, could change how state returns look, too, which helps explain why forms and guidance feel like moving targets.
How to handle your filing for now
Tax professionals and the state lay out the same three basic paths: wait for the Legislature to act, file an extension, or file now on the assumption that Arizona will conform to the federal rules. Each option comes with trade-offs tied to whether you expect a refund and how complicated your situation is. If you are counting on a federal refund and want that money sooner, many advisers say you can file your federal return now and either hold off on the state return or have your preparer wait to submit it until lawmakers resolve the fight.
Practical steps if you decide to wait
Talk with your tax preparer about whether to file a federal-only return for now, request an extension, or simply delay filing your Arizona return until ADOR or the Legislature offers final instructions. Keep detailed records of tips, overtime and any other items that might qualify for new deductions. If you do file early and end up needing to amend, the Arizona Department of Revenue has said it will provide instructions and that amended returns filed by Oct. 15, 2027 will not face penalties.
For now, patience may be the least painful option for many Arizonans. The forms are already in your hands, but the rules that govern them are still being hammered out down at the Capitol, so check ADOR’s guidance and talk with your preparer before you lock in your state return.
