Use the Arizona Tax Form Calculator Form 140PY Schedule A(PY): Arizona Part-Year Resident 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 140PY Schedule A(PY) is used by part-year residents to report and prorate itemized deductions that apply only to the portion of the year they lived in Arizona. Unlike a standard itemized deduction schedule, Schedule A(PY) adjusts each deduction category to ensure only expenses connected to the taxpayer’s Arizona residency period are included. This is essential for correctly calculating taxable income on Form 140PY.
Part-year residents must report total federal allowable deductions and identify which portions apply to the time they were Arizona residents. Because Arizona uses a ratio-based formula to align deductions with residency status, Schedule A(PY) ensures fairness by preventing the use of full-year deductions when only part of the year was spent as an Arizona resident.
How Part-Year Itemized Deductions Work in Arizona
Schedule A(PY) mirrors the structure of the federal Schedule A but applies Arizona-specific adjustments and a residency proration factor. The most significant steps include:
- Compute medical deductions: Medical expenses exceeding allowable federal thresholds are included on line 3 after subtracting reimbursements (line 1 minus line 2).
- Calculate taxes paid: State and local taxes, real estate taxes, and personal property taxes are combined on line 6.
- Include interest and charitable contributions: Mortgage interest, gifts to charity, and other qualified deductions are reported and totaled through line 19.
- Apply the part-year residency ratio: Form 140PY calculates an allocation ratio (line 13), which limits deductions to the portion applicable to Arizona residency. This prorated amount appears on line 22.
- Carry the prorated total to Form 140PY: The final deduction amount adjusts the taxpayer’s Arizona taxable income calculation.

Understanding Prorated Deductions for Part-Year Residents
Arizona requires part-year residents to prorate itemized deductions so only the portion attributable to the time spent living in the state applies to their tax calculation. This ensures the deductions align proportionally with Arizona-source income and residency duration.
Common deductions that require proration include:
- Medical and dental expenses
- Real estate and personal property taxes
- Mortgage interest and home equity interest
- Cash and non-cash charitable contributions
- Other miscellaneous federal itemized deductions
Because some deductions may relate to property or activities outside Arizona, prorating prevents over-claiming and is required even when expenses are paid during the residency period. The ratio multiplier ensures deductions stay proportional to Arizona-adjusted income.
Schedule A(PY) interacts closely with the main Form 140PY and the standard deduction increase worksheet. Both must be calculated together for accurate tax results.

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.
