Exemption provision for purchases made by the Department of Transportation for road construction projects

This bill exempts the Minnesota Department of Transportation (MnDOT) from paying sales tax on materials, supplies, and equipment purchased for road construction, improvement, and maintenance projects. It directly affects MnDOT and contractors working on state highway projects by eliminating a sales tax burden on these specific purchases. The exemption applies to all materials incorporated into public highway projects, as added to Minnesota Statutes section 297A.71. The provision becomes effective for purchases made after June 30, 2025.
