Common filing mistakes
Paying paper cost unnecessarily
Online filing is cheaper and usually simpler.
Using an invalid registered office
The registered office must be a physical Idaho street address, not only a P.O. box.
Forgetting annual report because it is free
The annual report is still required every year.
Getting tax accounts out of order
For many businesses, EIN comes after formation, then Idaho tax/employer accounts follow.
