New Iowa employers need four things in place before that first payroll run: a federal EIN from the IRS, a withholding account with the Iowa Department of Revenue, an SUI account with Iowa Workforce Development, and workers' compensation coverage. Handle new hire reporting and pick payroll software while you're at it.

Hiring your first employee in Iowa sets off a short chain of registration requirements at both the federal and state level. Skip one and you risk penalties, a delayed first payroll, or a scramble later to backfill paperwork. Here's the order that actually works.
Registration Overview
Every new Iowa employer needs the following pieces in place. Most take a few minutes to a few days to process, so start early.
- Federal Employer Identification Number (EIN)
- Iowa withholding tax account (Iowa Department of Revenue)
- Iowa SUI account (Iowa Workforce Development)
- Workers' compensation insurance
- New hire reporting through the Centralized Employee Registry
- A payroll system to run it all
Step 1: Get Your Federal EIN
Your Employer Identification Number (EIN) is your federal tax ID. You'll use it on federal filings, both state registrations below, your business bank account, and every payroll you run.
Apply online at IRS.gov/EIN. The application is free, and the IRS issues your EIN the moment you finish.
Step 2: Register with Iowa Department of Revenue
Visit the Iowa Department of Revenue website to open a state withholding account. This is what lets you legally withhold Iowa state income tax from employee paychecks and remit it on the schedule the state assigns you. New hires fill out an Iowa W-4 (Form 44-019), which drives how much you withhold; use our W-4 Helper if you want a plain-English walkthrough of the form.
From the Payroll Desk
Don't wait until your first payroll to register. State accounts can take several business days to activate, and you can't deposit withholding without one. Start as soon as you know you're hiring.
Step 3: Register for SUI
Open a State Unemployment Insurance account through Iowa Workforce Development (IWD). Once approved, you'll be assigned:
- An employer account number
- Your initial SUI rate: 1.000% for new non-construction employers, 5.400% for new construction employers
- A quarterly filing schedule
SUI is an employer-paid tax, and for 2026 it applies to the first $20,400 of each employee's wages, a wage base that dropped sharply from the prior year under recent state legislation. See our Iowa SUI Rates 2026 guide for the full rate table.
Step 4: Workers’ Compensation Insurance
Most Iowa employers must carry workers' compensation insurance to cover employees injured on the job, and coverage is generally required from the first employee you hire. You buy this coverage through a private insurance carrier, not directly from the state.
If a claim ever gets disputed, it's handled by the Workers' Compensation Division at the Iowa Department of Inspections, Appeals, and Licensing (DIAL). Compare quotes from a few carriers before you buy; rates vary quite a bit by industry classification.
Forming a Business First?
If you still need to set up your business entity before you can register as an employer, our guide to forming an LLC in Iowa walks through that process step by step.
Step 5: New Hire Reporting
Iowa law requires you to report every new hire and rehire within 15 days of the hire date, through the Centralized Employee Registry. That's tighter than the 20-day federal floor, so treat 15 days as your real deadline. The information helps enforce child support orders and catches unemployment fraud early.
See our New Hire Reporting guide for what information you'll need to submit.
Step 6: Set Up Payroll
Once your accounts are open, you're ready to actually run payroll. This is where most new employers realize how much manual tracking is involved: withholding tables, SUI, deposit deadlines, and quarterly returns all have to line up correctly every single pay period.
Gusto calculates and files your Iowa withholding and SUI automatically, handles new hire reporting for you, and runs about $40 a month plus $6 per employee. It's a reasonable starting point if you're doing this yourself for the first time.
