Employers who have elected to reimburse the state instead of paying unemployment tax contributions (i.e., reimbursing employers) are subject to interest on any benefits charged to their account (HB 5, 2010 legislative session). The chart below contains the assessed Trust Fund Interest (TFI) rate for previous years.
When you receive a quarterly Statement of Benefit Charges, Request for Reimbursement (UI-R448), you will notice a separate line-item charge for Trust Fund Interest. The statute below explains how TFI is calculated.
KRS 341.275(3)(a) Payments in lieu of contributions shall be made in accordance with the provisions of this subsection. (a) At the end of each calendar quarter or at the end of any other period as determined by the secretary, the cabinet shall bill each nonprofit organization (or group of such organizations) which has elected to make payments in lieu of contributions for an amount equal to the full amount of regular benefits plus one-half (1/2) of the amount of extended benefits paid during such quarter plus any prior period adjustments, which are attributable to service performed in covered employment in the employ of such organization plus interest on the total amount billed at the average rate of earnings in the unemployment insurance fund for the prior calendar year. All interest collected under this subsection shall be credited to the unemployment insurance fund.
