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
Is Form 301 used for amended returns?
Yes. When amending a return involving credits, Form 301 must be recompleted to reflect corrected amounts, removed credits, or added credits. If the corrected return results in credit recapture, Part III of Form 301 calculates the amount owed. Taxpayers filing amended returns should also include Form 300 and any corrected credit schedules to ensure Arizona can recompute tax liability accurately.
Can taxpayers claim both the Arizona and federal foreign tax credits?
Yes, Arizona residents may claim both, but they must coordinate claims carefully. If a taxpayer takes a foreign tax deduction on their federal return instead of a federal credit, Arizona generally requires them to reverse that deduction before applying the Arizona credit. Likewise, if the foreign tax is refunded after filing, both federal and Arizona returns may require amendments. For step-by-step examples, see the guidance linked on the AZ-309 calculator page.
Can charitable donations increase the standard deduction?
Arizona provides an increased standard deduction adjustment for certain charitable contributions—check the state section.
What documentation must accompany Arizona Form 131?
Arizona typically requires: (1) a copy of the death certificate, (2) Form 131 completed and signed by the claimant, and (3) if applicable, court letters of personal representative appointment. When no personal representative exists, individuals claiming based on funeral or medical expenses must attach receipts or payment confirmations. If the spouse claims the refund, no probate documentation is required, but the spouse must still provide the death certificate. For electronically filed returns where attachments cannot be included, taxpayers must mail the documentation to the Arizona Department of Revenue with a cover note referencing the e-file confirmation. You can refer to the instructions included with the form at the AZ-131 calculator page.
How are refunds and payments handled on Form 140?
Refunds and balances due are determined by comparing total tax after credits with total payments and withholding. Form 140 incorporates Arizona withholding from W-2s and 1099s, estimated tax payments, extension payments, refundable credits, and certain credit transfers. Any excess withholding or refundable credits generate a refund, while an underpayment results in a balance due. Taxpayers may also designate part of their refund to voluntary Arizona funds or apply it to next year’s estimated tax. Instructions for refund allocation and electronic payment methods can be found on the Form 140 filing guide at Arizona Form 140.
