Example. A files a petition for readjustment of partnership items in the United States Court of Federal Claims. A's tax liability would be increased by $4,000 if partnership items on A's return were conformed to the partnership return, as adjusted by the notice of final partnership administrative adjustment. A has an unpaid liability of $10,000 attributable to nonpartnership items. A is required to deposit $4,000 in order to satisfy the jurisdictional requirement.
