Sales tax: distribution; reporting and earmark of auto-related sales tax for the comprehensive transportation fund; provide for. Amends secs. 6 & 25 of 1933 PA 167 (MCL 205.56 & 205.75) & adds sec. 18a.

This bill requires Michigan businesses selling car parts and accessories to separately report and pay sales tax on those specific items starting October 1, 2027. To prepare for this change, the state Department of Treasury must define which products count as car parts by March 31, 2027, and create a new form for businesses to use. Companies will need to set up systems to identify these items at the point of sale and submit distinct payments for them alongside their regular monthly tax returns. The bill amends existing state tax laws to establish these new reporting and payment procedures without changing how the tax revenue is currently distributed.
