What this means in practice

Filing fees are often set in a state fee schedule and can change. Check the secretary of state's current fee schedule before you file, and expect extra charges for optional services such as expedited processing, certified copies, or name reservations.

Missing a required report or tax payment can lead to late fees and, after a period, administrative dissolution or loss of good standing. Put the due date on a calendar from the day the LLC is formed, since the first report may be due within the first year.

An LLC formed in one state that does business in another state may need to register there as a foreign LLC. That registration usually carries its own filing fee and its own report obligations in the second state.
