What payroll tax accounts should new businesses register for?

Payroll Tax Accounts for New Businesses in Arizona

When starting a new business in Arizona, registering for the correct payroll tax accounts is essential to ensure compliance with state and federal tax requirements. Proper registration supports accurate tax withholding, reporting, and payment processes.

Required Payroll Tax Accounts

• Federal Employer Identification Number (EIN): Obtain an EIN from the IRS. This is necessary for all payroll tax filings, including federal income tax withholding, Social Security, and Medicare taxes.
• Arizona Transaction Privilege Tax (TPT) License: While primarily a sales tax license, some businesses may need this for certain taxable services related to payroll operations. Confirm applicability based on your business activities.
• Arizona Withholding Tax Account: Register with the Arizona Department of Revenue (ADOR) to withhold state income tax from employee wages. This account is mandatory if you have employees working in Arizona.
• Arizona Unemployment Insurance (UI) Account: Register with the Arizona Department of Economic Security (DES) to pay state unemployment insurance taxes. This supports unemployment benefits for your employees.

Additional Operational Considerations

• Recordkeeping: Maintain accurate payroll records to support tax filings and audits. This includes wage reports, tax deposits, and employee information.
• Reporting Requirements: File periodic payroll tax returns with both federal and state agencies according to their schedules (e.g., quarterly wage reports and tax payments).
• Employee Classification: Correctly classify workers as employees or independent contractors to ensure proper tax withholding and reporting.
• Automation: Consider payroll software or services that integrate federal and Arizona payroll tax registrations and filings to reduce errors and save time.

As of 2026, always verify registration requirements directly with the Arizona Department of Revenue and the Arizona Department of Economic Security since payroll tax rules and procedures may change.
