This bill establishes a refundable sales and use tax exemption for construction materials used in specific projects within the city of Fairmont, Minnesota. The exemption applies to materials and supplies for UV/biosolids projects purchased between September 11, 2024, and January 11, 2027; for storage tank projects purchased between January 1, 2025, and June 2, 2026; and for public works buildings purchased between May 31, 2021, and March 8, 2024. The tax will be collected as if the standard rate applied, and refunds for eligible purchases will not be issued until after June 30, 2025.

Additionally, the bill includes an appropriation from the general fund to the commissioner of revenue to cover the refunds associated with these exemptions. The effective dates for the various exemptions are retroactive to align with the specified purchase periods for each type of project.
