Why does my unemployment tax rate keep changing, and who is supposed to catch that?

Your state unemployment insurance tax, often called SUTA or SUI, comes with a rate that changes annually. The state calculates a new rate for your business each year based on something called experience rating. Essentially, the more unemployment claims former employees have filed against your account, the higher your rate goes. Fewer claims and a stable employment history bring the rate down over time.

Every January, typically in the first few weeks of the year, your state department of labor or employment agency mails a notice with your new contribution rate for the year. Some states post this online as well. The notice includes your rate and the wage base it applies to, which is the maximum amount of each employee’s wages subject to unemployment tax for that year.

If no one reads that notice and updates your payroll system, the system keeps using last year’s rate. You could be overpaying or underpaying unemployment tax for twelve months before anyone notices. Underpayment means you owe back taxes plus penalties and interest. Overpayment means cash went out the door that didn’t need to.

So who is supposed to catch this? It depends on your setup. If you run payroll in-house with software like QuickBooks or Gusto, you are responsible for entering the new rate when the notice arrives. The software doesn’t know your rate changed unless you tell it. If you use a payroll service or have someone managing your payroll externally, they should be watching for that notice and making the update.

ClearLedgers® includes an annual review of unemployment tax rates as an explicit part of our payroll scope. For clients using our full-service payroll, we watch for the rate notice, update the payroll system, and confirm the new rate is in place before the first payroll of the year runs. For clients who run their own payroll but want oversight, the same annual rate review is built into our Payroll Oversight service.

Each state also has its own wage base, which is the maximum earnings per employee that unemployment tax applies to. Georgia’s wage base is different from California’s, which is different from Texas’s. If you have employees in multiple states, the rates and wage bases all need to be current for every state. Missing one creates the same problem of wrong taxes accumulating all year.

The notice typically arrives in January, sometimes late December. Keep an eye on your mail during that window, and if you don’t receive one, contact your state’s unemployment agency to request it. Don’t assume no news means the rate stayed the same. Rates and wage bases can also change at the state level from year to year, so current information should always be verified.

If you’re not sure who is handling this for your business, or if you’re finding out the hard way that nobody has been watching, bookkeeping services in Alpharetta and across Georgia, South Carolina, and the U.S. from ClearLedgers can help you get current and stay current going forward.
