30 Del. C. § 562

(a) Upon the adjudication of bankruptcy of the taxpayer in any bankruptcy proceeding, or upon the appointment of a receiver for the taxpayer in any receivership proceeding, before any court of the United States or any state or territory or of the District of Columbia, any deficiency (together with all interest, penalties, additional amounts and additions to the tax provided by law) determined by the Director in respect of any tax may be immediately assessed if such deficiency has not theretofore been assessed in accordance with law.

(b) Claims for the deficiency and for interest, penalties, additional amounts and additions to the tax may be presented for adjudication in accordance with law, to the court before which the bankruptcy or receivership proceeding is pending, despite the pendency of a protest before the Director under § 523 of this title or the pendency of proceedings before the Tax Appeal Board under § 544 of this title with respect to such deficiency. No protest shall be filed with the Director under § 523 of this title and no petition shall be filed with the Tax Appeal Board under § 544 of this title with respect to a deficiency after the adjudication of bankruptcy or appointment of the receiver.

(c) Every receiver, personal representative, trustee in bankruptcy, assignee for the benefit of creditors or other like fiduciary shall give such notice of qualification as such to the Director as may be required by the Director.
