Arizona’s 1099 filing requirements are narrower than the federal ones: the state only wants a copy of Form 1099-NEC or 1099-MISC if you actually withheld Arizona income tax from the payment. If no Arizona withholding happened, you file the 1099 with the IRS and stop there. The one standing exception is Form 1099-S for the sale of Arizona real estate, which goes to the Arizona Department of Revenue regardless of withholding.
When Arizona Actually Wants a Copy
The Arizona Department of Revenue (ADOR) requires Form 1099-NEC and Form 1099-MISC submissions only when the form reports Arizona income tax withholding. Pay a contractor $5,000 with no Arizona withholding obligation, and the state has no interest in the form. The federal 1099 still goes to the IRS on the normal schedule.
Form 1099-S is different. If the real property sits in Arizona, the state wants the form whether or not any tax was withheld. This catches nonresident sellers whose transactions did not trigger withholding but still involve Arizona property.
One point worth checking against your other-state habits: Arizona does not participate in the IRS Combined Federal/State Filing Program. Sending your 1099s to the IRS does not push a copy to Phoenix. You submit Arizona’s copies separately.
What Counts as Arizona-Source Income
Because the state filing hinges on withholding, and withholding hinges on whether the payment is Arizona-source income, that is the question to settle first. For services, the test is where the work happens. A nonresident who performs work physically in Arizona is earning Arizona-source income, no matter where the payer is based or where the check is cut.
Arizona’s administrative code confirms this for professional service providers. Nonresident attorneys, accountants, engineers, and similar professionals must treat the entire fee for services performed in Arizona as Arizona-source income, even if they are not regularly doing business in the state. Workers who split time between Arizona and elsewhere apportion based on the ratio of Arizona work to total work.1Cornell Law School. Arizona Admin Code R15-2C-601 – Income of a Non-resident
Payments to Arizona residents for work done entirely outside the state generally do not require Arizona withholding. Neither do payments to nonresidents for work performed entirely outside Arizona. No withholding, no state 1099 filing.
Withholding Rate and Waivers
When you pay a nonresident for services performed in Arizona, you are required to withhold Arizona income tax. The obligation reaches beyond employee wages to contractor payments, rents, royalties, and other Arizona-source income paid to nonresidents.
Arizona’s individual income tax rate is a flat 2.5%, in effect since tax year 2023.2Department of Administration Human Resources. New Arizona Income Tax Withholding Rates Effective For Wages Paid After December 31, 2022 Withholding applies to the Arizona-source portion of the payment.
A nonresident who expects their actual Arizona tax liability to fall below the standard withholding amount can apply to the ADOR for a waiver or reduced rate. If the recipient hands you an approved waiver, you can withhold accordingly. Without that paperwork, you withhold at the standard rate. Under-withholding lands on the payer, not the recipient, so when documentation is unclear the safer move is to withhold.
Forms and Deadlines
Arizona does not accept 1099s as standalone submissions. They ride in as attachments to an annual withholding reconciliation that also covers your wage withholding.
Which Reconciliation Form You File
If you file Arizona withholding returns quarterly, you reconcile on Form A1-R. If you file annually, you use Form A1-APR.3Arizona Department of Revenue.

If your workflow is built around the federal filing dates, you will be late in Arizona.
Form 1099-S for Arizona real estate transactions carries a later deadline, generally March 31 of the following year.
How to Submit
Forms A1-R and A1-APR must be filed electronically through AZTaxes.gov.3Arizona Department of Revenue.

When you send 1099s on paper or optical media, include Arizona Form A1-T, the Withholding Tax Transmittal, as a cover sheet so the ADOR can match the copies to your withholding account.
Penalties
Arizona charges separate penalties for filing late and paying late, and they stack.
- Late filing runs 4.5% of the tax due per month or partial month, capped at 25%.4Arizona Legislature. Arizona Revised Statutes 42-1125 – Civil Penalties
- Late payment runs 0.5% of the unpaid tax per month, capped at 10%.
- A business that files late and pays late can reach 35% of the tax due, plus interest from the original due date.
Failing to withhold when you should have creates a separate problem. The ADOR can hold the payer directly liable for the amount that should have been withheld, and if the failure is treated as negligence, an additional 10% penalty on the deficiency can apply.
Interest accrues on any unpaid balance from the original due date at a rate tied to the federal rate. Interest cannot be waived.
Requesting Penalty Abatement
If you think a penalty was assessed in error or that you had a legitimate reason for missing the deadline, you can request abatement on Arizona Form 290. The standard is reasonable cause: you have to show ordinary business care and prudence that still fell short through circumstances outside your control. Reliance on incorrect professional advice, serious illness, and destruction of records by fire or natural disaster are the kinds of grounds the ADOR will consider.
Abatement can knock out the penalty but not the interest. Even a granted request leaves you owing the underlying tax and the interest that has accrued on it. File the request early, because penalties keep running until the return is in and the tax is paid, whether or not an abatement request is pending.
