When the initial Form 1120 was filed with Schedule G, my client failed to state that he held 50% stock and another individual held the remaining 50% stock.  Do I need to amend the return using Form 1120X?  The initial filing had no income, no deductions, and no taxable income.  There were no tax payments.  Part I does not apply.  Part II is used to explain Part I changes.

What would be the correct way to address so that both individuals are listed as stockholders with 50% stock?
