Quick Answer

New Wyoming employers must: (1) obtain a federal EIN from the IRS, (2) register with the Wyoming Department of Revenue for any state business taxes that apply to their operations, (3) register for an SUI account with the Wyoming Department of Workforce Services, and (4) obtain workers' compensation insurance. Complete all registrations before running your first payroll.

When you hire your first employee in Wyoming, you trigger a handful of registration requirements at the federal and state level. Missing any of these steps can result in penalties, delayed payroll, and compliance headaches. This walkthrough covers everything, in order.

Registration Overview

Here's a checklist of what every new Wyoming employer needs:

  • ☑ Federal Employer Identification Number (EIN)
  • ☑ Wyoming state tax registration, if applicable (Wyoming Department of Revenue)
  • ☑ Wyoming SUI account (Wyoming Department of Workforce Services)
  • ☑ Workers' compensation insurance
  • ☑ New hire reporting setup
  • ☑ Payroll system or software

Step 1: Get Your Federal EIN

Your Employer Identification Number (EIN) is your federal tax ID. You need it for everything: federal tax filings, state registrations, opening a business bank account, and running payroll.

Apply online at IRS.gov/EIN. It's free and you receive your EIN immediately.

Step 2: Register with Wyoming Department of Revenue

Visit the Wyoming Department of Revenue website to register for any state business tax accounts your company needs, such as sales or use tax. Wyoming has no state income tax, so there is no employer withholding account to set up here. Your payroll-specific registration happens with the Department of Workforce Services in the next step.

From the Payroll Desk

Don't wait until your first payroll to register. State registrations can take days to process. Start as soon as you know you'll be hiring.

Step 3: Register for SUI

Register for a State Unemployment Insurance account through the Wyoming Department of Workforce Services. You'll be assigned:

  • An employer account number
  • Your SUI rate, based on the average experience of employers in your industry classification
  • Quarterly filing requirements

SUI is an employer-paid tax on the first $33,800 of each employee's wages for 2026. See our Wyoming SUI Rates 2026 guide for details.

Step 4: Workers’ Compensation Insurance

Wyoming requires most employers to carry workers' compensation coverage from the first employee. Unlike most states, Wyoming runs its workers' comp program directly through the Department of Workforce Services rather than through private insurance carriers, so you register and pay premiums with the state rather than shopping the open market.

Your premium is based on your industry classification and payroll, and it's billed alongside your other Department of Workforce Services filings.

Step 5: New Hire Reporting

Federal and Wyoming law require you to report every new hire within 20 days of their start date. This information is used to enforce child support orders and prevent unemployment fraud. Report through the Wyoming New Hire Reporting program. See our New Hire Reporting guide for more detail.

Step 6: Set Up Payroll

With registrations complete, you're ready to run payroll. Wyoming's lack of a state income tax means your ongoing work is mostly federal: withholding, FICA, FUTA, and depositing on schedule, plus the quarterly SUI report. Whether you handle that in-house with payroll software or hand it to a payroll service, make sure whoever runs it understands that Wyoming has no state withholding return to file, only the SUI report.
