Arizona Payroll Tax and Registration Guide

To comply with Arizona payroll tax regulations, employers must submit specific company details before Beyond can begin processing payroll:
Arizona Employer Tax ID and applicable state/local tax identifiers
State-assigned tax rates, determined based on your business’s type, size, and duration of operation
TPA access and Power of Attorney documents, which are typically required by Arizona tax agencies for Beyond to file and pay on your behalf

Keeping this information accurate and current is critical. Beyond depends on these details to correctly file and remit taxes. Mistakes or missing data could result in compliance issues or penalties, and Beyond cannot assume liability for incorrect tax information.

If you employ workers in more than one state, be aware that each jurisdiction has different requirements. You’ll need to follow the appropriate rules for each state separately.

  • Complete the joint application for the Arizona Transaction Privilege Tax (TPT) license
  • This process registers your business for withholding tax and unemployment insurance at the same time
  • You’ll receive your account numbers and tax rate via mail
  • Online registration may take 2–3 weeks to process
