I was told that the warehouse in California is there only to store the goods until they can bring them into their Nevada warehouse used for distribution. They were not able to move everything at once, limited spacing I guess.

Having said that, if it turns out to be different, can I file a state return without a secretary of state number and an entity number that is no longer active? What is required for nonqualified foreign corporations for tracking purposes?

Also, if we are retaining a new EIN would I need a "final" tax return for the old corporation, to close out the accounts?
