Ad valorem tax; add categories for energy projects and extend deadline for certain exemptions, extend deadlines and revise fee-in-lieu minimum for certain projects.
HB 1063 modifies Mississippi's ad valorem tax rules to support energy projects. It expands the definition of eligible "projects" to include battery energy storage systems, adds energy manufacturing/operation businesses to tax exemption categories, and extends key deadlines - pushing the construction completion deadline for exemptions to 2036 and the authorization deadline for exemptions to 2035. The bill allows counties to exempt up to 50% of a qualifying energy project's assessed value from property taxes for 10 years, provided the project meets a $100 million capital investment threshold. This directly affects energy developers and counties managing tax incentives for large-scale renewable energy and storage facilities.
