How to Do Payroll in Wyoming

Last reviewed: July 2026

Wyoming has a reputation as an easy state to do business in, and payroll is one place that reputation holds up. There's no state income tax, no state withholding form, and no separate state payroll tax agency to file with beyond unemployment insurance. That said, "simple" doesn't mean "nothing to do." You still need federal registrations, a Wyoming SUI account, a legal pay schedule, and clean year-end filings. Here's the order to handle it in.

1. Get a Federal EIN

Every employer needs an Employer Identification Number from the IRS before running payroll. It's free, and you can apply online at IRS.gov. Most applicants receive their EIN the same day. You'll use this number on every federal filing, your Wyoming state registrations, and your employees' W-2s.

Apply for your EIN before you make a job offer, not after your first employee shows up. State registrations and payroll software setup both depend on having the number in hand.

2. Register With Wyoming State Agencies

New Wyoming employers register in two places. The Wyoming Department of Revenue handles state business tax accounts (sales, use, and excise tax registrations if your business needs them), and the Wyoming Department of Workforce Services handles your unemployment insurance account, which is the one payroll registration every employer with a Wyoming employee actually needs.

Set up your SUI account with the Department of Workforce Services as soon as you know you'll be hiring. Processing can take a few days, and you need your account number before your first quarterly wage report is due.

3. No State Income Tax Withholding

Wyoming does not levy a state income tax on wages, so there is no state withholding form for employees to fill out and nothing to remit to a state tax agency each pay period. Your federal withholding obligations stay the same as anywhere else: collect a federal Form W-4 from each employee, withhold based on the IRS tables, and deposit federal income tax, Social Security, and Medicare on your regular schedule.

If you're helping an employee fill out their W-4, our W-4 helper tool walks through the form step by step. And if you want to check what a Wyoming employee actually takes home after federal taxes, run the numbers through our free paycheck calculator.

4. Set Up State Unemployment Insurance

SUI is the one state-level payroll tax Wyoming employers pay. For 2026, the taxable wage base is $33,800 per employee. Wyoming doesn't hand new employers a single flat starting rate the way most states do. Instead, the Department of Workforce Services assigns your rate based on the average experience of other employers in your industry classification, so your actual percentage depends on what kind of business you run.

You'll file a quarterly wage report with the Department of Workforce Services and pay SUI on those wages. Quarterly reports are due by the last day of the month following the end of each quarter: April 30, July 31, October 31, and January 31.

5. Pay Frequency and Final Pay

Wyoming requires employers to pay wages at least once a month. Employers in railroad, mining, oil and gas exploration or production, factory, and mill work face a stricter rule and must pay at least twice a month. Most small businesses outside those industries choose biweekly or semi-monthly anyway, since monthly pay can be a hard sell to hourly employees.

When an employee leaves, whether they quit or are let go, Wyoming law says their final paycheck is due by the next regular payday. There's no requirement to cut a check on the spot, but don't push it past that next scheduled payday either.

6. Deposit and Filing Calendar

Here's what a typical Wyoming employer's calendar looks like:

7. Year-End W-2 Filing

At year end, you'll issue a Form W-2 to every employee and file copies with the Social Security Administration by January 31. Because Wyoming has no income tax, box 15 through 17 on the W-2 (state wages and withholding) stay blank for Wyoming employees. That's normal and expected. There's no separate state reconciliation return to file the way there would be in a state with income tax withholding, which removes one more task from your year-end list.
