Arizona Payroll Agencies: Official Links for Employers
Last reviewed: July 2026
Every employer in Arizona ends up dealing with the same short list of government offices: one for tax registration, one for unemployment insurance, one for reporting new hires, and one for wage rules. This page keeps the official links in one place so you never have to dig for them through search results and lookalike sites. Bookmark it; we keep it current.
| What you need | Official Arizona resource |
|---|---|
| Tax / revenue department (withholding & registration) | Arizona Department of Revenue |
| Unemployment insurance (SUI) registration & reporting | Arizona Department of Economic Security - Unemployment Insurance Tax |
| New-hire reporting | Arizona New Hire Reporting Center |
| Labor department (wage & hour rules) | Industrial Commission of Arizona - Labor Department |
A note on lookalike sites: many well-ranked pages imitate state portals and charge fees for registrations the state handles free. The links above go to government sites only. If a site asks for payment just to give you an account number, close the tab.
