Early each year, the UIA issues its Tax Rate Determination for Calendar Year 20__, Form UIA 1771. It shows an employer's prior Actual Reserve, benefits charged and contributions paid (basis of the CBC and ABC components) since the last annual determination, and the employer's new Actual Reserve.

It also shows the employer's 12-month total and taxable payrolls, and the Required Reserve, as well as the employer's 60-month taxable payroll, and the benefit charges in that 60-month period. It then shows the calculated amount of each component of the tax rate, and the rate itself.
