Economic development; revise incentives relating to certain projects.

HB 4045 revises Mississippi's economic development incentives by ending the income tax exemption for data center projects after 2026 and requiring that for projects with over $2 billion in capital investment (entering fee-in-lieu agreements after July 2026), a portion of the fee must be deposited into the new Mississippi Strategic Development Fund. The bill updates definitions of qualifying projects under the Major Economic Impact Act and adjusts how nuclear facility payments are distributed to counties and municipalities. These changes primarily affect large businesses seeking tax incentives for major capital investments, with the new fund intended to support strategic economic development initiatives. The Mississippi Development Authority will manage the fund for specified purposes upon legislative appropriation.
