How Does State Unemployment Tax Work for a Small Business?

By Bill Stilwell · Last reviewed October 17, 2026

The short answer

Register with your state workforce agency for an unemployment insurance account before your first payroll. Your state assigns a tax rate and a wage limit, and you file and pay each quarter. Paying state unemployment tax on time also earns you a big credit against the federal unemployment tax.

What this means

Unemployment insurance pays benefits to workers who lose their jobs through no fault of their own. Employers fund it through two taxes:

State unemployment tax, often called SUTA (State Unemployment Tax Act tax). You register with your state workforce agency. The state sets your rate, usually a starting rate for new employers that later changes based on your history. It applies to each employee’s wages up to a yearly limit set by the state.
Federal unemployment tax, called FUTA (Federal Unemployment Tax Act tax). The Internal Revenue Service (IRS) sets the rate at 6.0% on the first $7,000 of each employee’s wages each year. Most employers get a credit of up to 5.4% for state unemployment tax paid, so the federal rate usually works out to 0.6%.

To get the full federal credit, you generally have to pay your state tax by the federal Form 940 due date. In states that borrowed federal money to pay benefits and haven’t paid it back, employers can get a smaller credit, which means a higher federal bill.

In most states, unemployment tax is paid by the employer, not taken from employee pay. A few states also take a small amount from employees, so check yours.

This page also covers state unemployment from Part 23 (23.4.3).

Made-up example: Summit Ridge Roofing hires three crew members. The owner registers with the state workforce agency, gets a new-employer rate notice, gives it to the payroll service, and checks each quarter that the state return was filed and paid.

Why it matters

Late or missing state payments can shrink your federal credit, so you pay more federal tax.
States charge penalties and interest for late reports and payments.
Your rate can go up if former employees collect benefits charged to your account, so how you handle separations matters.

Who this applies to

Most businesses that pay employees. The federal Form 940 is generally required if you paid $1,500 or more in wages in any calendar quarter, or had at least one employee for some part of a day in 20 or more weeks, in the current or prior year. States set their own coverage rules, and some cover employers sooner. Nonprofits and household employers have special rules. Check your state workforce agency.

How to do it

Register with your state workforce agency before your first payroll (see 10.3.1 State Employer Registration).
Save the rate notice and give it to your payroll service. Rates often change each year, so update it when the new notice arrives.
File quarterly wage reports and pay the tax on the state’s schedule.
Pay state tax on time so you keep the full federal credit.
File federal Form 940 each year and make federal deposits when required (see 10.3.4 Payroll Tax Deposits).
Answer state claim notices quickly when a former employee files for benefits. Missing the deadline can lead to charges to your account.
Register in each state where your employees work.

What proof to keep

State registration confirmation and account number
Every yearly rate notice
Quarterly wage reports and payment confirmations
Federal Form 940 and deposit confirmations
Your responses to benefit claim notices

Common mistakes

Not updating the rate when the new notice arrives each year.
Ignoring claim notices from the state.
Paying the state late and losing part of the federal credit.
Forgetting a remote employee who works in another state.
Assuming owners are covered or excluded without checking. It depends on your business type and state.

When to get help from a pro

Payroll professional or certified public accountant (CPA): when you first hire, when you get a claim notice you’re unsure about, or if your rate jumps. Questions to ask:

What is my state’s wage limit and my current rate?
Is my state a credit reduction state this year?
How should I respond to this claim notice?

Questions people ask

What is SUTA? It’s the common name for state unemployment tax, which employers pay to fund unemployment benefits.

How is my rate set? New employers usually get a starting rate. Later, the state adjusts it based on your history, including benefits charged to your account.

How does state tax affect FUTA? Paying state tax on time gives you a credit of up to 5.4% against the 6.0% federal rate.

Do I take it out of employee pay? In most states, no. A few states also collect a small employee share.

Audit check

Question: Is the business registered for state unemployment in every state where it has employees, and are reports and payments on time?
Pass looks like: Account open before first payroll. Current rate in payroll. Quarterly reports filed and paid. Form 940 filed. Claim notices answered.
Fail looks like: No account. Old rate in payroll. Late payments. Ignored claim notices.
Evidence to collect: Registration, rate notices, quarterly reports, payment confirmations, Form 940, and claim responses.
