Tax Increment Financing Act — Museum Authority Exemption (SB1141)

Current understanding

SB1141 would amend multiple sections (201, 301, 402, 523, 603, 703, 803) of the Recodified Tax Increment Financing Act (2018 PA 57; MCL 125.4201 et seq.) to exclude taxes levied under the history museum authorities act from the definition of tax increment revenues. This means history-museum-authority millages would not be captured by TIF authorities (DDAs, brownfield authorities, corridor improvement authorities, etc.), preserving that revenue stream for museum purposes. The bill is tie-barred with SB1139 and SB1140 and has been introduced; no chamber action reported.
