About Idaho business records

Idaho charges no fee for the annual report, which is due in the business's anniversary month. Filing on paper instead of online through SOSBiz adds a $20 manual processing fee to most filings.

The public record of every Idaho LLC and corporation belongs to the Idaho Secretary of State, Business Services, whose search goes by SOSBiz.
