Exempts receipts from sales of materials, supplies, and services for certain affordable housing projects from sales and use tax.

This bill (S 1484) exempts sales tax on construction materials, supplies, and services used for specific affordable housing projects. It directly affects housing sponsors who have secured federal, state, or local subsidies for projects where all units are restricted to moderate, low, or very low-income residents (as defined by state law). The exemption applies to materials/services used in building, improving, or repairing qualifying housing, requiring sponsors to apply through state-prescribed procedures. This policy change reduces construction costs for affordable housing developers by removing a sales tax burden on essential building inputs.
