Ok, looking further into this: “Nevada uses the "Reserve Ratio" formula to determine previous experience, which is the method used by a majority of the states. The Employment Security Division maintains a permanent "Experience Record" for each employer, consisting of accumulated taxes paid, accumulated benefits charged to his account, and average taxable payroll for the prior 3 years. Each year, the employer's reserve ratio is calculated from his experience record to determine his tax rate under the schedule in effect.” http://ui.nv.gov/ESSHTML/ui_information.htm http://ui.nv.gov/ESSHTML/ui_information.htm
