Heads up: The state fee is the floor. Third-party filing services will offer to handle this for you at 2-10× the state cost. If your setup is simple, filing yourself through the Iowa portal is straightforward; if it's not (foreign qualification, complex ownership, non-US members), the extra service cost is often justified.
