Sales and use tax exemptions apply to materials, labor, and services for eligible flood restoration projects located in federally declared major disaster areas, provided through a quarterly remittance process

Eligibility for tax relief is limited to legal or beneficial owners of damaged property at the time of the disaster, or their relatives by blood, marriage, or adoption

Sales and use tax provisions take effect October 1, 2026 and expire July 1, 2031; property tax changes apply to taxes levied for collection in 2027 and thereafter
