MO SB217

Creates state and local sales and use tax exemptions for new data storage centers acquiring or constructing facilities on or after August 28, 2011, with a minimum $5 million investment over 36 months, covering utilities, machinery, equipment, computers, and construction materials.

Defines new data storage centers as facilities engaged in data processing, hosting, and related services (NAICS 518210) or internet publishing and broadcasting (NAICS 519130) that were not previously operated as data storage centers.

Provides separate exemptions for expanding existing data storage centers with at least $1 million in net new investment over 12 months, exempting only the incremental increases in utilities and equipment costs above historical baseline levels.

Requires projects to submit plans to the Department of Economic Development for conditional approval, then provide proof of required investment amounts to receive refunds of previously paid sales taxes and ongoing exemption certificates from the Department of Revenue.

Exemption certificates remain valid only while taxpayers operate the facility; successor taxpayers receive new certificates without needing additional investments to maintain exemption eligibility.
