The officer or agency designated by the President under this subchapter shall, notwithstanding the filing of any claim or the institution of any suit under this subchapter, pay any tax incident to any such property, or the earnings, increment, or proceeds thereof, at the earliest time appearing to him to be not contrary to the interest of the United States. The former owner shall not be liable for any such tax accruing while such property, earnings, increment, or proceeds are held by such designee, unless they are returned pursuant to this subchapter without payment of such tax by the designee. Every such tax shall be paid by the designee to the same extent, as nearly as may be deemed practicable, as though the property had not been vested, and shall be paid only out of the property, or earnings, increment, or proceeds thereof, to which they are incident or out of other property acquired from the same former owner, or earnings, increment, or proceeds thereof. No tax liability may be enforced from any property or the earnings, increment, or proceeds thereof while held by the designee except with his consent. Where any property is transferred, otherwise than pursuant to section
of this title, the designee may transfer the property free and clear of any tax, except to the extent of any lien for a tax existing and perfected at the date of vesting, and the proceeds of such transfer shall, for tax purposes, replace the property in the hands of the designee.
