Water Conservation Rebate Tax Parity Act

This bill expands tax exclusions for homeowners by adding water conservation, storm water management, and wastewater management rebates to the existing tax-free treatment for energy efficiency subsidies. It directly affects residents receiving rebates from public utilities, local governments, or storm water providers for qualifying installations like low-flow fixtures, rain barrels, or septic system upgrades (with wastewater rebates limited to principal residences). Key provisions redefine "water conservation measure" and "storm water management measure" to clarify eligible upgrades and explicitly include water utilities and storm water providers under tax-exclusion rules. The changes apply to rebates received after December 31, 2021, without altering tax treatment for prior rebates.
