Mississippi MS Department of Employment Security

Mississippi Department of Employment Security operates the AccessMSTax portal at accessmstax.mdes.ms.gov, an online platform for unemployment insurance tax administration in Mississippi. It serves employers registered in the state, allowing them to manage their unemployment tax accounts electronically. Through the system, businesses can register for a state unemployment tax account, file quarterly wage and tax reports, and submit tax payments online. The portal also allows employers to update account information, view filing history, and manage correspondence with the department. MDES uses this system to administer the state's unemployment insurance tax program, which funds benefits paid to eligible unemployed workers in Mississippi.
