MODERATE
The bill was significantly rewritten to shift its focus from requiring taxpayers to disclose detailed financial data to the state, to authorizing the Department of Business, Economic Development, and Tourism to study tax expenditures and access return information for evaluation purposes. This change removes mandatory disclosure requirements for individual taxpayers while adding specific legal protections and penalties to safeguard taxpayer confidentiality during state reviews.
Scope change
The bill's scope changed from imposing obligations on taxpayers to claim credits/exemptions to granting the state department authority to conduct studies and access data, with a specific addition of felony penalties for unauthorized disclosure of tax return information.
REQUIREMENT
Removed the requirement for taxpayers to file detailed disclosure forms containing names, costs, and job creation data when claiming tax credits or exemptions.
Added a mandate for the Department of Business, Economic Development, and Tourism to study the effectiveness of tax expenditures and submit annual reports to the legislature.
ENFORCEMENT
Introduced specific felony penalties for state officers or employees who intentionally disclose confidential tax return information obtained during these evaluations.
DEFINITION
Replaced the old requirement for taxpayer disclosure forms with new statutory language defining who is authorized to access confidential tax return information for state evaluations.
