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 documentation do I need to support a claim on Form 140PTC?
Taxpayers should maintain records verifying rent paid or property taxes assessed and paid. Homeowners must keep county property tax statements, while renters should obtain receipts or landlord statements itemizing rent amounts per month. Arizona may request verification during processing, especially when the credit claimed is high relative to income. Taxpayers who receive SSI or other benefits should also retain award letters proving eligibility. Additional explanation and examples for documentation appear on the reference page for AZ-140PTC.

Do charitable contributions affect Schedule A(NR) differently for nonresidents?
Charitable contributions reported on Schedule A(NR) are included as part of total itemized deductions before applying the Arizona nonresident ratio. This differs from resident forms such as the 140, where charitable contributions may also influence the standard deduction increase worksheet. Nonresidents do not receive the separate charitable increase because Form 140NR applies the ratio instead. Taxpayers wanting to compare outcomes between itemizing and taking the standard deduction can do so using the Arizona nonresident calculator at Form 140NR.
What if I live in Arizona but work in another state?
The work state may tax those wages. Claim a credit on your Arizona return where eligible. Model it in the full calculator.
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.
