Delaware Code (Titles 8, 9, 25, 30)
30 Del. C. § 552 — Collection procedures
(a)
Any tax imposed by this title or Title 4 shall be collected by the Director, and the Director may establish the mode or time for the collection of any amount due under this title or Title 4 including setoff of such amount as a debt owed to a claimant agency pursuant to § 545(a) of this title, if not otherwise specified. The Director shall, on request, give a receipt for any amount collected under this title or Title 4. The Director may authorize incorporated banks or trust companies to receive any tax imposed under this title or Title 4, in such manner, at such times and under such conditions as the Director may prescribe, and the Director shall prescribe the manner, times and conditions under which the receipt of tax by any such bank or trust company is to be treated as a payment of tax to the Director.
(b)
The Director shall, as soon as practicable after an assessment of tax, interest, penalty, additional amount or addition to the tax becomes final pursuant to § 522 or § 530 of this title, give written notice to each person liable for the payment of the assessed amount, stating the amount so assessed and demanding payment thereof within 10 days of the date of such notice. Such notice shall be sent by mail to such person at the last known address. If the amount assessed exceeds the applicable threshold of $1,000, such notice shall be sent by certified or registered mail. (The applicable threshold in this subsection is subject to annual adjustment as more fully set forth in § 515 of this title.) Except where the Director determines that collection would be jeopardized by delay, if any amount is assessed prior to the last date, including any date fixed by extension, prescribed for payment of such amount, payment of such amount shall not be demanded under this subsection until after such date.
