28 U.S.C. § 960: Tax liability

Any officers and agents conducting any business under authority of a United States court shall be subject to all Federal, State and local taxes applicable to such business to the same extent as if it were conducted by an individual or corporation. the tax is a property tax secured by a lien against property that is abandoned under section 554 of title 11 , within a reasonable period of time after the lien attaches, by the trustee in a case under title 11; or payment of the tax is excused under a specific provision of title 11. the tax was not incurred by a trustee duly appointed or elected under chapter 7 of title 11; or before the due date of the tax, an order of the court makes a finding of probable insufficiency of funds of the estate to pay in full the administrative expenses allowed under section 503(b) of title 11 that have the same priority in distribution under section 726(b) of title 11 as the priority of that tax.
