How SUI rate changes work.
State unemployment insurance (SUI) rates are not fixed. They move with your experience rating, which former employees' claims drive. When a claim is filed and you do not respond within the state's window, the state approves it by default, and that raises your experience rating and then your rate.
The compounding is what catches employers off guard. One missed notice can raise a rate for three years or more. For a company with 50 employees, a 0.5% rate increase on a $9,000 taxable wage base means an extra $2,250 a year, or $6,750 over three years from one missed notice.
Each state has its own notice schedule, response windows and penalties, so an employer in ten or more states has many more notices to catch. Most agencies send rate notices 30 to 60 days before the new rate takes effect; in that window you can protest a rate you believe is wrong, if you respond in time.
The way to control SUI costs is catching the notice when it arrives and responding within the state's window. The usual drivers of higher costs are uncontested unemployment claims, missed rate notices, late quarterly reports and unanswered state audits.
SUI costs, for firms and for employers.
SUI costs for CPA firms managing multi-state clients
One missed notice raises one client's rate for years, and the risk repeats across every client and every state. Each state runs its own deadlines, rate notices and quarterly filings, so a firm needs one place where every client's notices and dates sit.
SUI costs for multi-state employers
Each state has its own taxable wage base, rate schedule, filing deadlines and penalties. A missed rate notice in a high-wage-base state such as Oregon (2026 taxable wage base of $56,700; Kreto-computed, not yet checked by a CPA) can cost more than several missed notices in states with a lower base.
Questions about SUI costs.
How much does a missed SUI notice typically cost?
It depends on your state, your number of employees and the type of notice missed. Enter those inputs above and the calculator shows the three-year cost for your case.
How long do SUI rate increases last?
Most states calculate experience ratings over a three-year rolling window. A rate increase from a missed notice or an uncontested claim usually affects your rate for three years before it rolls off.
Can I contest an SUI rate change after the deadline?
In most states, once the protest deadline passes, the rate is final for that period. Some states allow a late protest for good cause, but that is not guaranteed and varies by state.
What is a taxable wage base?
The taxable wage base is the most of each employee's wages that SUI tax applies to. It varies by state: in 2026, from $7,000 in California to $78,200 in Washington (Kreto-computed, not yet checked by a CPA).
How does an uncontested UI claim affect my SUI rate?
When a former employee files a claim and you do not respond within the state's window (often 10 to 21 days), the state approves the claim by default. The benefits paid are charged to your account, which raises your experience rating and then your SUI rate.
What states have the highest SUI rates?
Maximum SUI rates differ by state and change from year to year. Rates vary by state and by employer history; check your state agency's current schedule.
