Gov. Terry Branstad signed Senate File 135 into law on April 24, 2015. The bill increases political expenditures triggering filing requirements for committees to $1,000.

The bill also amends the definition of an independent expenditure to be one or more expenditures in excess of $1,000. It also makes anonymous contributions in excess of $25 illegal.

Beginning January 1, 2016, all committees not already required to file electronically must do so by 4:30 p.m. of the day the filing is due.

Senate File 135 takes effect July 1, 2015.
