SB 529 Wisconsin Senate · 2025-2026 Regular Session

Relating to: repeal of obsolete tax credits and tax provisions. (FE)

SB 529 repeals outdated tax provisions and updates specific tax rules in Wisconsin's statutes. It removes obsolete tax credits (like those in sections 71.03(7)(d) and 77.54(57d)(a)1) and modifies college savings account deductions, limiting annual tax deductions for contributions to $5,000 per beneficiary (adjusted annually for inflation). The bill also clarifies that income from disaster relief work performed by out-of-state businesses does not increase a business's taxable income in Wisconsin. These changes primarily affect taxpayers claiming college savings deductions or involved in disaster relief work with out-of-state businesses.
