30 Del. C. § 560

(a) The liability, at law or in equity, of a transferee of property of a taxpayer for any tax, interest, penalty, additional amount or addition to the tax due under this title or due under Title 4 shall be assessed, paid and collected in the same manner, and subject to the same provisions and limitations, as in the case of the tax, interest, penalty, additional amount or addition to the tax with respect to which the liability was incurred, except as provided in this section. The term “transferee” includes donee, heir, legatee, devisee and distributee.

(b) In the case of the liability of an initial transferee, the period of limitation for assessment of any liability is within 1 year after the expiration of the period of limitation for assessment against the transferor; in the case of the liability of a transferee of a transferee, within 1 year after the expiration of the period of limitation for assessment against the preceding transferee, but not more than 3 years after the expiration of the period of limitation for assessment against the initial transferor; except that if, before the expiration of the period of limitation for the assessment of the liability of the transferee, a proceeding for the collection of the liability has been begun against the initial transferor or the last preceding transferee, respectively, then the period of limitation for assessment of the liability of the transferee shall expire 1 year after the proceeding is terminated.

(c) If, before the expiration of the time provided in subsection (b) of this section for the assessment of the liability, the Director and the transferee have both consented in writing to its assessment after such time, the liability may be assessed at any time prior to the expiration of the period agreed upon. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the previous period. For the purpose of determining the period of limitation on credit or refund to the transferee of overpayments of tax made by such transferee, or of overpayments of tax made by the transferor of which the transferee is legally entitled to credit or refund, such agreement, and any extension thereof, shall be deemed an agreement and extension thereof referred to in § 539(c) of this title. If the agreement is executed after the expiration of the period of limitation for assessment against the taxpayer with reference to whom the liability of such transferee arises, then in applying the limitations under § 539(b) of this title on the amount of the credit or refund, the periods specified in § 539(a) of this title shall be increased by the period from the date of such expiration to the date of the agreement.

(d) For purposes of this section, if any person is deceased or is a corporation which has terminated its existence, the period of limitation for assessment against such person shall be the period that would be in effect had death or termination of existence not occurred.
