Processing time
Idaho publishes a live processed-through date on SOSBiz rather than a duration, with one queue covering all business filings; on 17 August 2026 it read 10 August, and the site banner gave approximately 7 to 10 days from the date of filing, counted in days rather than business days. Expedited service adds $40 and is typically processed within 8 business hours; same day service adds $100 and must be received by 1pm Mountain. Filing on paper costs $20 more and buys no speed
Expedite
$40 for eight working hours, $100 for same working day if delivered before 1pm

Important to know
The annual report is free on every channel. Paper and in-person filings add a $20 manual data-entry charge, which is a channel surcharge rather than a report fee.
