Arizona Payroll Tax Registration

A Complete Guide for Employers

By US TAX BAY

Planning to hire employees in Arizona? Before you process your first paycheck, it’s crucial to register for the necessary payroll tax accounts. In Arizona, this includes employer withholding tax and unemployment insurance tax. Whether you're launching a business or expanding into Arizona, US TAX BAY is here to help streamline your payroll registration process.

Understanding Arizona Payroll Taxes

Arizona employers are required to register for:

• Arizona Withholding Tax (state income tax withholding)

• Arizona Unemployment Insurance Tax (SUI)

Both registrations are completed using Form JT-1, also known as the Joint Tax Application.

Step 1: Register for Arizona Employer Withholding Tax

Agency:

Arizona Department of Revenue (ADOR)

Required Form:

Form JT-1 – Joint Tax Application for a Business License

Who Needs to Register?

You must register for Arizona employer withholding tax if you:

• Pay wages to employees who live or work in Arizona

• Are required to withhold state income tax from employee paychecks

• 
  

How to Register:

• Online: Visit the Arizona Department of Revenue AZTaxes.gov Portal to complete the Joint Tax Application.

• By Form: Download and fill out Form JT-1 and submit it by mail.

After registration, you’ll receive your Withholding Tax license number, which must be used when filing returns and submitting payments.

Step 2: Register for Arizona Unemployment Insurance Tax (SUI)

Agency:

Arizona Department of Economic Security (DES)

Required Form:

Form JT-1 – Joint Tax Application (same form as withholding)

Who Needs to Register?

If you hire one or more employees, you are generally required to register for unemployment insurance. Registration is required for:

• New employers with payroll in Arizona

• Employers expanding into Arizona from other states

  
  

How to Register:

• Complete Form JT-1 online or submit the paper form to the Arizona Department of Economic Security.

• Once processed, you’ll receive a State Unemployment Tax (SUTA) account number.

  
  

Filing Method for Both Taxes:

• Online: Preferred method via AZTaxes.gov

• Paper Form: Available for those who prefer mail-in submissions

  
  

Why Compliance Matters

Failing to register can result in:

• Penalties and interest

• Delayed payroll processing

• Ineligibility to file required quarterly returns

Timely and accurate registration ensures smooth payroll operations and helps your business stay legally compliant.
