Arizona Form 140NR Schedule A(NR) – Itemized Deductions for Nonresidents
Last reviewed: 2025-11-16
Use the Arizona Tax Form Calculator Form 140NR Schedule A(NR): Arizona Nonresident Itemized Deductions as a stand alone tax form calculator to quickly calculate specific amounts for your 2026 Arizona state tax return. Alternatively, you can use one of our Combined Federal and State Tax Estimators to quickly calculate your salary, tax, and take-home pay.
Arizona Form 140NR Schedule A(NR) allows nonresidents to calculate itemized deductions that may be claimed instead of the standard deduction on Arizona Form 140NR. Because nonresidents can only deduct expenses related to Arizona-source income, the schedule includes a full set of federal-style deduction lines, worksheets, and a final prorating step that applies Arizona’s nonresident allocation ratio. This ensures only the correct portion of medical expenses, taxes, mortgage interest, gifts and other allowable deductions are recognized on the Arizona nonresident return.
The schedule mirrors the federal Schedule A categories but adjusts them for Arizona rules, including the medical 7.5% threshold, state disallowed taxes, federal limits, charitable provisions and the additional subtraction worksheet. All amounts ultimately flow into the prorated deduction used to reduce Arizona taxable income on Form 140NR.
How Schedule A(NR) Works
Schedule A(NR) is structured to calculate federal-style itemized deductions and then adjust them for Arizona’s nonresident laws. The main process includes:
- Medical and dental expenses: Taxpayers list total medical costs and subtract 7.5% of federal AGI, matching federal rules.
- Taxes paid: Arizona does not allow a deduction for state income tax; only eligible taxes may be included.
- Interest: Mortgage interest and investment interest are entered according to federal rules.
- Gifts to charity: Contributions follow federal rules, including carryovers and substantiation requirements.
- Miscellaneous categories: Casualty/theft losses and other deductions that still qualify federally are included.
- Arizona subtraction adjustments: The schedule includes an additional subtraction worksheet to remove amounts disallowed at the state level.
- Compute federal-style total itemized deductions: After all categories and adjustments, the schedule determines the base deduction amount.
- Apply the nonresident allocation ratio: The Arizona ratio from Form 140NR (Arizona income ÷ federal AGI, capped at 1.00) is applied to prorate the deduction for nonresident use.
This process ensures deductions reflect only the portion attributable to Arizona-sourced income, which prevents over-claiming and aligns the return with state law.

Understanding Arizona Nonresident Deduction Rules
Arizona requires that nonresidents prorate itemized deductions because only income earned within Arizona is taxable by the state. The allocation ratio ensures parity: taxpayers cannot claim a full deduction against partial Arizona income. This prorated approach also applies to exemptions and several credits on Form 140NR.
Nonresidents often benefit from completing Schedule A(NR) even if they ultimately select the standard deduction. Comparing the prorated itemized deduction with the Form 140NR standard deduction is essential for minimizing taxable Arizona income. The calculator automates this comparison and all worksheet logic, eliminating manual proration and reducing filing errors.

Frequently Asked Questions
What is Arizona Form 140EZ and who is eligible to file it?
Arizona Form 140EZ is the simplest of all Arizona resident income tax returns. It is specifically designed for full-year residents with very basic tax situations—typically wage earners or retirees whose income and deductions require no adjustments or additional schedules. Form 140EZ supports only a limited range of income types and does not allow itemized deductions, business income, capital gains adjustments, Arizona additions, or complex credits. Taxpayers eligible for Form 140EZ must meet strict criteria, including filing as Single or Married Filing Jointly, having only basic income sources, and claiming the standard deduction. It is ideal for those who want a quick and streamlined method to file their Arizona taxes without navigating the complexity of longer forms.
How do credits interact with amended returns filed using Form 140X?
Credits must be recalculated as if the return were being filed for the first time. If the amendment increases income or changes filing status, previously claimed credits may decrease. If the amendment adds a missed credit—such as those calculated on Forms 321, 322, 323 or 348—taxpayers should attach the full credit form to the amended return. Unused credits with carryforward provisions may need adjustment across multiple years.
Can Form 131 be used when amending a deceased taxpayer’s prior-year return?
Yes. If a deceased taxpayer is owed money from an amended return—such as correcting income, claiming a missed credit or adjusting withholding—the claimant must resubmit Form 131 with the amended return. The Arizona Department of Revenue requires the form each time a refund is issued, even if one was previously accepted for another year. Guidance on pairing Form 131 with amended returns can be reviewed alongside the amended return calculator at Arizona Form 140X.
Does Form 140EZ allow itemized deductions or only the standard deduction?
Form 140EZ only permits the standard deduction. Itemized deductions—including mortgage interest, medical expenses, property taxes, charitable contributions, and other Schedule A items—cannot be claimed on this form. The Form 140EZ standard deduction is predefined based on filing status and does not allow for additional increases such as charitable deduction boosts available on other forms. Taxpayers who wish to itemize must instead file Form 140.
What are the annual credit limits for QFCO contributions?
Arizona sets distinct limits for Single/HOH/MFS filers and for Married Filing Jointly. Taxpayers may claim only up to the allowable limit. Any contributions above that limit cannot be refunded but may be carried forward for up to five years. These limits are separate from those used for QCO contributions (Form 321), meaning taxpayers can claim both credits in the same tax year.
