This bill proposes a sales and use tax exemption for construction materials and supplies used in the development of two water mains in Brooklyn Park, Minnesota, aimed at supporting the city's biotech innovation district. Specifically, it establishes a refundable exemption for materials and equipment purchased between November 30, 2025, and January 1, 2029. The bill stipulates that the tax will be collected as if the standard rate applied, but will then be refunded in accordance with existing provisions for similar projects.

Additionally, the bill includes an appropriation from the general fund to the commissioner of revenue to cover the refunds associated with this exemption. The effective date for this exemption aligns with the specified purchase period, ensuring that the financial benefits are available to support the construction efforts during that timeframe.
