Filing your 2017 Arizona state income tax return does not have to be overwhelming. Whether you are a first-time filer, a returning resident, or a small business owner, understanding the process will help you meet all requirements while avoiding costly mistakes. Arizona’s “mirror state” system calculates your state taxes using your federal adjusted gross income (AGI) as the starting point, making accuracy on your federal return essential before completing the filing process.
Submitting your return on time ensures you avoid late fees and interest while securing any refund you are entitled to receive. For example, filing promptly can help speed up a property tax refund if you qualify for one. You can choose between electronic filing through azdor.gov or paper submission, each with its requirements and procedures. The Arizona Department of Revenue may occasionally display messages like "Verification successful, waiting" or "azdor.gov needs to review" to maintain the security of your connection before proceeding. These measures protect your information and maintain strong performance security in the state’s online systems.
This guide will walk you through the 2017 process from start to finish, including eligibility rules, selecting the correct Arizona form, entering accurate information, making payments, tracking your refund, and avoiding common mistakes. By following these steps, you can file confidently, comply with state laws, and keep the process as stress-free as possible.
Arizona requires most residents to file a state income tax return if they meet certain income thresholds, which vary by filing status:
These rules apply to full-year residents, part-year residents, and in some cases nonresidents who earned Arizona-source income. Even if you are not required to file a federal return, you may still need to file an Arizona form.
Arizona is considered a “mirror state” because it uses your federal AGI as the starting point for calculating your state taxes.

Selecting the correct Arizona form is essential to ensure your return is processed accurately and without unnecessary delays. The Arizona Department of Revenue offers multiple Arizona tax forms for 2017, and your choice depends on residency status, income level, and the deductions or credits you plan to claim.
Use Arizona Form 140 if:

Form 140A is intended for taxpayers with simpler returns. You can use this form if all of the following apply:

Before you start, collect all the paperwork you will need:

Arizona is a mirror state, meaning your federal adjusted gross income (AGI) is the starting point for your Arizona form. Completing your federal return first helps avoid calculation errors when completing your state return.
Refer to the guidance in the previous section to choose between Arizona Form 140, 140A, or 140EZ. If filing online at azdor.gov, you may see prompts like "Verification successful." You will be waiting for azdor.gov to review your request before continuing. These steps review the security of your connection and ensure performance security for your filing session.
Provide accurate details:
Arizona filing status options include:
When filing online, you may be asked to confirm your status by a human by completing a quick verification step, such as a CAPTCHA, to confirm your identity.
2017 exemption amounts were:
Make sure your entries are correct before moving on to the income section.
If you file electronically and an error occurs, the system may send you a Ray ID reference number. Keep this number for your records if you need AZDOR to provide assistance or troubleshoot an issue.
Once your forms are complete, you must submit your 2017 Arizona tax return. You can file electronically or by paper; each method has its procedures and benefits.
Electronic filing is the fastest and most secure way to submit your return. Advantages include:
When filing online at azdor.gov, you may encounter prompts such as "azdor.gov needs to review" or "review the security of your connection before proceeding." These verification measures help maintain performance security and protect your personal information. Sometimes, you may see messages like Verify you are human before proceeding to the next page.
Eligible taxpayers can access free e-file programs. AZDOR lists approved providers on its website, and many commercial tax software platforms also support Arizona e-filing.
If you choose to file a paper return:

Include any required schedules, W-2s, and 1099s. Make sure your return is signed and dated before mailing.
If you owe taxes for 2017, you must submit payment by the filing deadline to avoid penalties and interest. The Arizona Department of Revenue (AZDOR) offers several convenient payment methods, both online and offline.
Paying online through azdor.gov is secure and efficient. You can choose from:
When paying online, AZDOR may prompt you to review the security of your connection before proceeding. Sometimes, you need to verify that you are human to continue. These steps are part of the state’s performance security protocols.
If you prefer to pay by mail:
Respond promptly to avoid further charges if you receive a notice from AZDOR regarding unpaid taxes. Sometimes you may also be eligible for a credit against your tax liability if overpayments or specific contributions apply.
Knowing how to check the status of your refund or confirm a remaining balance helps you stay informed and avoid surprises. The Arizona Department of Revenue provides multiple options for both.
When using the online tool, you may encounter prompts like "needs to review" or "connection" before proceeding if the site is verifying security before showing sensitive data.
When using the online tool, you may encounter prompts like a need for a review or connection before proceeding if the site is verifying security before showing sensitive data.

Avoiding frequent errors when filing your 2017 Arizona tax return can save time, reduce the risk of delays, and prevent unnecessary penalties. Below are the most common mistakes identified by the Arizona Department of Revenue.
Some taxpayers mistakenly use federal taxable income instead of federal adjusted gross income (AGI) when completing their Arizona forms. Since Arizona is a mirror state, AGI is the correct starting point for your calculation.
Errors in calculating exemptions for dependents, qualifying parents or grandparents, or age/blindness adjustments are standard. Always review the eligibility criteria before completing this section.
Unsigned returns, missing Social Security numbers, or failure to attach W-2s, 1099s, or required schedules can cause processing delays. Whether filing online or on paper, ensure these details are complete before completing your submission.
Manually calculated returns often contain addition or subtraction errors. Electronic filing reduces this risk, but you should review all figures before submitting.
When filing electronically, respond to prompts such as “verify you are human” or “review the information before proceeding.” These steps protect your data and ensure accuracy before your return is accepted.
Before you send your 2017 Arizona tax return, use this checklist to confirm that every step has been completed accurately. This final review can prevent delays, reduce the need to respond to notices, and help ensure the security of your personal information.
If you missed the 2017 deadline, file as soon as possible to minimize late filing and payment penalties. Interest accrues on unpaid balances, so even partial payments can reduce costs. You should also submit an extension form if applicable. While an extension gives more time to file, it does not extend your payment deadline.
Yes. Many taxpayers qualify for free e-filing through azdor.gov or approved software providers. Eligibility is usually based on income thresholds or participation in specific federal programs. Free e-file options often include built-in error checking and secure connection verification before submitting your return, helping to ensure accuracy and protect your personal information throughout the process.
Commonly overlooked deductions include property taxes paid, mortgage interest, qualifying charitable contributions, and specific exemptions for parents or grandparents. Some taxpayers also forget credits for contributions to Arizona public schools or certified philanthropic organizations. Reviewing federal and state guidelines ensures you maximize deductions and credits while remaining compliant. Always double-check requirements and maintain documentation to support your claims in case of review.
You can request an extension by filing Arizona Form 204 or using your approved federal extension (Form 4868). Extensions allow you to submit your return until October 15, 2018, but payment is still due by April 17, 2018. Filing late without paying can result in penalties and interest, so pay as much as possible before the original due date to reduce charges.
If you and your spouse meet Arizona’s residency requirements, you may file jointly as part-year residents. In this case, you’ll use the correct Arizona tax forms for part-year returns, such as Form 140PY. You must report all income earned during your residency period and Arizona-source income earned while living elsewhere. Accurate allocation ensures correct tax calculation and prevents processing delays.
If the IRS adjusts your federal return, you must report the changes to Arizona within 90 days. File an amended state return using Form 140X or send a copy of the IRS notice to AZDOR. This ensures your Arizona return matches your updated federal figures. Failure to report changes can result in penalties, interest, or additional tax assessments from the state.
An Arizona audit typically follows a federal audit or state review of discrepancies. You’ll receive a notice requesting documents, explanations, or clarification. Respond promptly to avoid penalties and further action. Keep organized records of income, deductions, and credits claimed. If you disagree with the findings, you have the right to appeal. Professional tax assistance can help ensure compliance and protect your interests.
