modify the requirements for a petition to refer an excess tax levy of a school district to a vote.

SB 223 modifies South Dakota's process for school districts to refer excess tax levies to voter approval. It changes the petition signature requirement from a flat 50 voters to "at least five percent of the registered voters" in the school district. The bill also adjusts notice rules, waiving newspaper publication requirements if the district mails the resolution to all property taxpayers within 20 days. This affects school districts seeking voter input on tax increases and directly impacts local taxpayers who may petition to refer levy decisions.
