What Is SUTA? State Unemployment Tax Explained

How state unemployment insurance tax works, how your rate is set and why wage bases differ so much between states.

Updated November 2, 2026 by the Wagevane editorial team.

SUTA (State Unemployment Tax Act) tax, also called SUI, funds the unemployment benefits a state pays to laid-off workers. Employers pay it in every state, and workers also contribute in Alaska, New Jersey and Pennsylvania.

How the tax is calculated

SUTA owed = your rate × each employee's wages up to the state wage base. Once an employee's year-to-date wages pass the wage base, you stop paying for that employee until January 1.

Wage bases vary widely

The highest wage base is Washington's at $78,200; the lowest are Arkansas, California, Florida, Louisiana, Tennessee at $7,000. A high wage base with a low rate can cost more than a low wage base with a high rate, so compare the dollar amount, not just the rate.

How your rate is set

States mail rate notices each year, usually in December. Check yours: errors happen, and voluntary contributions can lower your rate in some states.

SUTA and FUTA

Paying SUTA on time earns a credit of up to 5.4% against the 6.0% federal FUTA tax. When a state has an unpaid federal loan, the credit shrinks, raising FUTA for every employer in that state.
