Political contribution refund program repealed, and conforming changes made.

HF 3288 repeals Minnesota's political contribution refund program, which allowed voters to receive money back for campaign donations. This affects voters who participated in the program by claiming refunds for contributions to candidates or ballot measures. The bill ends the program by removing related statutes (including sections 290.06, subdivision 23) and sets a cutoff: refunds cannot be issued after June 30, 2026, for claims made after April 15, 2026. The bill also makes minor adjustments to other tax refund provisions that referenced the repealed program.
