A corporation or LLC generally comes into existence and becomes officially "incorporated" when the Articles of Incorporation (or Articles of Organization) are filed with the state. Becoming incorporated on the date of filing is usually the best option. However, if there is a reason that you require your corporation or LLC to become incorporated at a later date, states allow a delayed effective date, if so stated on the Articles of Incorporation. If desired, indicate the number of days after filing that you want your corporation to begin when filling out the online incorporation form. In most states, the date cannot be more than ninety days after filing.
