All contributory employers, including governmental entities and non-profit 501(c)(3) employers who have not elected to reimburse the Department under Section 41-31-620, are required to pay the interest surcharge in effect for a tax year. The interest surcharge effective for the applicable tax year will appear on the employer's annual rate notice and quarterly contribution report in combination with the Departmental Administrative Contingency Assessment (DACA). Certain employers are exempt from DACA per Section 41-27-410.
