Learn about online filing of your quarterly Unemployment Tax and Wage Report (UC-018).
Businesses determined liable to provide unemployment insurance coverage for their workers are required to
- submit Unemployment Tax and Wage Reports (UC-018) for each quarter they are covered, even for quarters during which no wages were paid, and
- to pay taxes each quarter taxable wages were paid.
Once you have been issued an Arizona unemployment tax account number, the Department of Economic Security (DES) will automatically mail UC-018 forms to you during the last month of each quarter.Failure to receive a report does not relieve you of the responsibility of filing a report or waive penalty assessments.
If you have an Arizona unemployment tax account number and do not receive a UC-018 from DES, contact the Employer Accounting Unit and request that a duplicate UC-018be generated for your account and mailed to you. Make sure to verify that your correct mailing address is on your account when you contact the Accounting Unit. Also, be aware that all such requested forms are generated in bulk only once per week and are mailed sometime during the next work week following the week the form is requested—the timing of this process is beyond the control of the Unemployment Tax program.
Once you have an Arizona unemployment tax account number, you are encouraged to submit quarterly wage reports and pay taxes by using our online filing and payment system. Your password to access the online system is issued on the preprinted UC-018 DES mails you each quarter. If you file online, DO NOT file the paper UC-018. However, instead of filing either online or entirely by paper form (UC-018), you may submit the tax and wage summary portion of your reports by paper form and the employee and wage detail portion by “magnetic media.” New magnetic media filers may only use compact discs for this purpose--see Magnetic Media Reporting and Electronic Filing (MMREF-1) (439 KB PDF) for detailed instructions and specifications. For additional information about Magnetic Media Reporting, please contact the Employer Accounting Unit.
