Inactive corporations.

Whenever a corporation has been completely inactive for an entire taxable year, in lieu of filing the statements and information otherwise required by this section, it may file a declaration, on a form to be provided by the department, subscribed by its president, if a resident of this state, and, if not a resident, then by another officer residing in this state, attesting to such inactivity. Such declaration must be filed prior to the otherwise due date for its Wisconsin return for such taxable year. Thereafter the corporation need not file such statements or information for any subsequent year unless specifically requested to do so by the department or unless in a subsequent year the corporation has been activated or reactivated.
