Subchapter IV. Enforcement

§ 551. Timely mailing.

(a) If any return, declaration of estimated tax, claim, statement, notice, protest or other document required to be filed, or any payment required to be made, within a prescribed period or on or before a prescribed date under the authority of any provision of the revenue laws of this State, other than § 331 of this title, is, after such period or such date, delivered by United States mail to the agency, officer or office with which such document is required to be filed, the date of the United States postmark stamped on the cover in which such document is mailed shall be deemed to be the date of delivery or the date of payment, as the case may be.

(b) This section shall apply only if the postmark date falls within the prescribed period, or on or before the prescribed date for the filing of the return, declaration, claim, statement, notice, protest or other document (determined with regard to any extension granted for such filing), or for making the payment (determined with regard to any extension granted for making such payment), and only if such document or payment was deposited in the mail, postage prepaid, properly addressed to the agency, officer or office with which such document is required to be filed or to which such payment is required to be made.

(c) If any return, declaration of estimated tax, claim, statement, notice, protest or other document or payment is sent by United States registered mail, such registration shall be prima facie evidence that such document or payment was delivered to the agency, officer or office to which addressed. To the extent that the Director shall prescribe, certified mail may be used in lieu of registered mail under this subsection.

(d) When the last day prescribed under the authority of the revenue laws of this State, including any extension of time, for performing any act falls on Saturday, Sunday or a legal holiday in this State, the performance of such act shall be considered timely if it is performed on the next succeeding day which is not a Saturday, Sunday or a legal holiday in this State.

§ 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.

§ 553. Period of collection after assessment; agreement for extension.

(a) Where the assessment of any amount of tax, interest, penalty, additional amount or addition to the tax imposed by this title or Title 4 has been made within the period of limitation properly applicable thereto, such amount may be collected by a proceeding in court under § 554 of this title, but only if such proceeding is begun:

(1) Within 10 years after the assessment of such amount has become final; or

(2) Prior to the expiration of any period for collection agreed upon in writing by the Director and the taxpayer before the expiration of such 10-year period.

(b) The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the period previously agreed upon.

(c) The provisions of subsection (a) of this section shall not affect collection by setoff against tax refunds due to the taxpayer, which setoff may occur whenever there exists an unpaid assessment of tax, interest, penalties, additional amounts or additions to the tax.

(d) The provisions of subsection (a) of this section shall not shorten the period during which a judgment for any amount entered in a court may be collected by execution upon such judgment.

(e) The running of the period of limitations on collections provided for in this section shall, in a case under Title 11 of the United States Code, be suspended for the period during which the Director is prohibited from collecting by reason of such case plus 6 months thereafter.

§ 554. Obtaining court judgment by filing certificate.

(a) If any amount of tax, interest, penalties, additional amounts or additions to the tax payable under this title or Title 4 has been assessed and was not paid when due, the Director may file in the office of the prothonotary of any county a certificate by paper or electronic transaction specifying the amount of such tax, interest, penalties, additional amounts and additions to the tax due, the name and last known address of the taxpayer liable for such amount and the fact that the Director has complied with all of the provisions of this title or predecessor provisions in the assessment of such amount. From the time of such filing, the amount set forth in the certificate shall thereupon be and constitute a judgment of record in such court with like force and effect as any other judgment of the court, except that the renewal provisions of § 4711 of Title 10 shall not be applicable, and a judgment lien obtained under this subsection shall automatically continue for a period of 20 years from the date of its entry. The prothonotary in each county shall enter all such certificates in the regular judgment docket and index them as soon as they are filed regardless of the county of the taxpayer’s residence.

(b) No property, legal or equitable, wages, salaries, deposits or moneys in banks (notwithstanding the provisions of § 3502 of Title 10), savings institutions or loan associations, or other property or income of any taxpayer shall be exempt from execution or attachment process issued upon, or from collection of, any judgment obtained under subsection (a) of this section. This section shall not apply to liens created under § 1345 of this title [repealed].

(c) Any judgment obtained under subsection (a) of this section on or after January 1, 1992, shall automatically continue for a period of 20 years from the date of its entry. Any judgment obtained under predecessor provisions of this section by virtue of a certificate filed prior to January 1, 1992, for tax, interest, penalties, additional amounts or additions to the tax shall continue for a period of 20 years from the original date of its entry even though, when such certificate was filed, such predecessor provision may have provided for a period of continuation of less than 20 years.

(d) Notwithstanding any contrary provision of § 4711 of Title 10, within the term of 20 years contemplated by subsection (a) of this section, the Director may renew the lien of such judgment for an additional term of 20 years by filing in the office of the prothonotary of any county a certificate by paper or electronic transaction specifying the amount of such tax, interest, penalties, additional amounts and additions to the tax due, the name and last known address of the taxpayer liable for such amount and the fact that the Director has complied with all of the provisions of this title in preparing such renewal. The prothonotary in each county shall enter all such certificates in the regular judgment docket and index them as soon as they are filed regardless of the county of the taxpayer’s residence.

§ 555. Release of lien.

The Director may at any time release all, or any portion of, the property subject to any lien arising under this chapter or subordinate such lien to other judgments, liens or security interests if the Director determines that the amount secured by such lien is sufficiently secured by an encumbrance on other property of the taxpayer or that the release or subordination of such lien will not endanger or jeopardize the collection of such amount.

§ 556. Execution of judgments.

(a) In general. — If any person liable to pay any assessed amount of tax, interest, penalty, additional amount or addition to the tax imposed under this title or other titles subject to this chapter neglects or refuses to pay such amount after a judgment has been obtained pursuant to § 554 of this title, or otherwise, the Director may execute upon such judgment as provided herein.

(b) Warrants for levy and sale of property. — The Director may issue a warrant directed to the sheriff of any county of this state commanding such sheriff to levy upon and sell the personal or real property of such person for the payment of the amount of the judgment and the cost of executing the warrant. The sheriff shall return such warrant to the Director and pay to the Director the money collected by virtue thereof within 60 days after receipt of the warrant. A copy of the warrant shall be filed with the Prothonotary and noticed on the regular judgment docket. All sales of real and personal property under authority of this section shall be made pursuant to the provisions of Title 10.

(c) Garnishment of bank accounts. — The Director may issue a notice of garnishment directed to any bank, commanding said garnishee, notwithstanding the provisions of § 3502 or § 4913(b) of Title 10, to set aside, account for, and pay over to the Division of Revenue on account of the debt any property owed to or held for the debtor by said bank. A copy of the notice of garnishment or an abstract thereof shall be filed with the Prothonotary and the fact of the garnishment noticed on the regular judgment docket.

(d) Garnishment of wages, salaries, and other amounts due. — The Director may issue a notice of garnishment directed to any person (other than a bank) owing to or holding for a judgment debtor any wages, salaries, money, credits and effects, contract rights or securities. The notice of garnishment shall command said garnishee to set aside, account for, and pay over to the Division of Revenue on account of the judgment all such property then in its possession or which may become due the judgment debtor by such person from time to time, until the judgment and costs of execution are paid. A copy of the notice of garnishment or an abstract thereof shall be filed with the Prothonotary and the fact of the garnishment noticed on the regular judgment docket. The Director shall notify the garnishee in writing when the judgment and costs have been satisfied.

(e) Duties of garnishee. — A person receiving a notice of garnishment pursuant to subsection (c) or (d) of this section shall respond to the Director or Revenue within 20 days after service of the notice, not counting the date of service. A garnishee who fails to comply with a notice of garnishment may, after notice and assessment pursuant to this chapter, be liable for a penalty equal to the amount the garnishee was instructed to set aside, account for, and pay over to the Division of Revenue. Thirty days after the mailing of the notice of proposed assessment of such penalty, it shall become final, excepting only those amounts for which the garnishee has filed a timely written protest with the Director under § 523 of this title.

68 Del. Laws, c. 187, §  170 Del. Laws, c. 186, §  174 Del. Laws, c. 159, §  3

§ 557. Nonresident taxpayer.

When notice and demand for the payment of any assessed amount of tax, interest, penalty, additional amount or addition to the tax imposed under this title or Title 4 is given to a nonresident taxpayer, and the Director determines that it is not practicable to locate property of the taxpayer sufficient in amount to cover the amount assessed, the Director shall send a copy of the certificate provided for in § 554 of this title to the taxpayer at the taxpayer’s last known address, together with a notice that such certificate has been filed with the Prothonotary of New Castle County. Thereafter, the Director may authorize the institution of any action or proceeding to collect or enforce such judgment in any place and by any procedure that a civil judgment of a court of record of this State could be collected or enforced. The Director may also, at the Director’s discretion, designate agents or retain counsel outside this State, for the purpose of collecting outside this State any assessed amounts due under this title or Title 4 from taxpayers who are not residents of this State. The Director may fix the compensation of such agents and counsel to be paid out of money appropriated or otherwise lawfully available for the payment thereof, and the Director may require of such agents and counsel bonds or other security for the faithful performance of their duties. The Director is authorized to enter into agreements with the tax agencies or departments of other states and the District of Columbia for the collection of taxes from persons found in this State who are delinquent in the payment of taxes imposed by such other states or the District of Columbia, on condition that such other states and the District of Columbia afford similar assistance in the collection of taxes from persons found in their jurisdictions who are delinquent in the payment of taxes imposed under this title or Title 4. The Director is authorized to enter into similar agreements with the Internal Revenue Service with respect to the collection of taxes imposed under this title and Title 4 and the taxes imposed under the internal revenue laws of the United States.

68 Del. Laws, c. 187, §  170 Del. Laws, c. 186, §  1

§ 558. Tax claims of other states.

(a) General. — The courts of this State shall recognize and enforce liabilities for taxes lawfully imposed by any other state which extends a like comity to this State, and the duly authorized officers of any such other state may sue for the collection of such taxes in the courts of this State. A certificate by the Secretary of State of any such other state that an officer suing for the collection of such a tax is duly authorized to collect the tax shall be conclusive proof of such authority. For the purposes of this section, the word “taxes” shall include interest, penalties, additional amounts and additions to the tax. Liability for interest, penalties, additional amounts and additions to the tax shall be recognized and enforced by the courts of this State to the same extent that the laws of such other state permit the enforcement in its courts of liability for interest, penalties, additional amounts and additions to the tax due this State under this title or Title 4. Nothing in this section shall be construed as giving the courts of this State jurisdiction to enforce liability for the taxes of any other state, except by an action against an individual who is a resident of this State or by an action against a corporation which is maintaining its principal office in this State at the time of the commencement of such action.

(b) Collection of tax debts of certain other governments. — (1) Definitions. — For purposes of this section:

a. “Claimant government” means any other state or agency of the United States that, in either case, extends a like comity for the collection of a tax debt owed to this State.

b. “Refund” means any taxpayer’s claim to repayment of an overpayment of a tax determined to be owed by this State.

c. “Tax debt” means any amount of tax imposed under the laws of the claimant government, including additions to tax for penalties and interest, which is finally due and payable to the claimant government, with respect to which any administrative remedies and appeals have been exhausted or have lapsed and which is legally enforceable, whether or not there is an outstanding judgment of such sum.

d. “Taxing Official” means a unit or official of a claimant government charged with the imposition, assessment or collection of taxes of that government.

e. “Taxpayer” means any person or entity identified by a claimant government for action by the Director of Revenue under this section, and, in the case of an intercept of a refund of personal income tax arising from the filing of a joint return, the taxpayer’s spouse.

(2) Request for intercept. — a. Except as provided in this subsection, a taxing official may:

1. Certify to the Director of Revenue the existence of a tax debt to a claimant government, and

2. Request the Director of Revenue to withhold any refund to which the taxpayer is entitled.

b. A taxing official may not certify or request the Director of Revenue to withhold a refund unless the laws of the claimant government allow the Director of Revenue to:

1. Certify a tax debt due,

2. Request the taxing official to withhold the taxpayer’s refund, and

3. Provide for the payment of the refund to Delaware.

(3) Certification to Director of Revenue. — Certification of a tax debt by the taxing official to the Director of Revenue shall include:

a. The full name of the taxpayer and, if in the sound discretion of the Director it will aid in identifying and locating the taxpayer, the taxpayer’s address;

b. The taxpayer’s Social Security number or federal tax identification number;

c. The amount of the tax debt, including a detailed statement for each taxable year showing tax, interest and penalty or data that, in the sound discretion of the Director of Revenue, sufficiently describes the tax debt; and

d. A statement that all rights to administrative remedies and appeals have been exhausted or lapsed and that the assessment of tax, interest and penalty is final and enforceable.

(4) Notice to taxpayer. — Upon receipt of a request for intercept and certification from a taxing official, the Director shall notify the taxpayer (and, in the case of a refund of any tax imposed upon the income of individuals, any spouse with whom the taxpayer filed a joint return) thereof and of the right to protest the intercept. The notice shall include a copy of the certification by the taxing official.

(5) Protest of intercept. — A taxpayer may protest an intercept of a refund pursuant to § 523 of this title (except that the time to protest shall be 30 days from the date of the Director’s notice of intercept pursuant to paragraph (b)(4) of this section and not 60 days). If a taxpayer shall file a timely protest, the Director shall:

a. Suspend the proposed intercept and impound the claimed amount of the taxpayer’s refund,

b. Pay to the taxpayer the unclaimed amount of the refund, if any,

c. Send a copy of the protest to the claimant government for determination of the protest on its merits in accordance with the laws of that state, and

d. Pay over to the taxpayer the impounded amount if the claimant government shall fail within 45 days of the date of the protest to re-certify to the Director of Revenue that the claimant government has reviewed the issues raised by taxpayer, that all administrative and judicial remedies provided under the laws of that state have been exhausted, and the amount of the tax debt finally determined to be due.

(6) Rights of spouses to refunds from joint returns. — If a proposed intercept is based upon the tax debt of only 1 individual and if the refund is based upon a joint personal income tax return, the nondebtor spouse shall have the right to protest the intercept of that spouse’s share of the refund in accordance with paragraph (b)(5) of this section, showing the nondebtor spouse’s proper share of such refund.

(7) Intercept and payment of refund. — Subject to the taxpayer’s rights of notice and protest, upon receipt of a request for intercept in accordance with paragraph (b)(2) of this section, the Director of Revenue shall:

a. Pay to the claimant government the entire refund or the amount certified, whichever is less;

b. Pay any refund in excess of the certified amount to the taxpayer; and

c. If a refund is less than the certified amount, withhold amounts from subsequent refunds due to the taxpayer provided the claimant government shall withhold subsequent refunds of taxpayers certified to the claimant government by the Director of Revenue.

(8) Director’s authority. — The Director of Revenue shall have the authority to enter into agreements with the taxing officials of claimant governments relating to:

a. Procedures and methods to be employed by a claimant government with respect to the operation of this section;

b. Safeguards against the disclosure or inappropriate use of any personally identifiable information regarding the taxpayer obtained or maintained pursuant to this chapter; and

c. A minimum tax debt, amounts below which, in light of administrative expenses and efficiency, shall, in the Director’s discretion, not be subject to the intercept procedures set forth in this section.

(9) Remedy not exclusive. — The collection procedures prescribed by this subsection are in addition to, and not in substitution for, any other remedy available by law.

(10) United States as claimant government. — Notwithstanding any other provision of this section, the Director may deem the government of the United States a claimant government provided the Director finds, based on specific action of the United States or House of Representatives or a Committee thereof, reason to believe the United States may extend a like comity for the collection of a tax debt owed to this State no later than January 1, 2001.

§ 559. Order to compel compliance.

(a) If any person wilfully refuses to file a tax return required by this title or Title 4, the Director may apply to a judge of the Superior Court for the county in which the taxpayer (or other person required to file such return on behalf of the taxpayer) resides, or, in the case of a corporate taxpayer or a taxpayer that is a partnership, estate or trust, for the county in which such taxpayer maintains its principal office in this State, for an order directing such taxpayer or other person to file the required return. If a person fails or refuses to obey such an order, such person shall be guilty of contempt of court.

(b) If any person wilfully refuses to make available any books, papers, records or memoranda for examination by the Director, or the Director’s representative, or wilfully refuses to attend and testify, pursuant to the powers conferred on the Director by § 563(c) of this title, the Director may apply to a judge of the Superior Court for the county in which such person resides for an order directing such person to comply with the Director’s request for books, papers, records or memoranda, or for the person’s attendance and testimony. If the books, papers, records or memoranda required by the Director are in the custody of a corporation, the order of the Court may be directed to any principal officer of such corporation. If a person fails or refuses to obey such an order, such person shall be guilty of contempt of court.

§ 560. Transferees.

(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.

§ 561. Jeopardy assessments.

(a) If the Director finds that the collection of a tax, whether or not the time otherwise prescribed by law for making a return and paying such tax has expired, or the assessment or collection of a deficiency for any year, current or past, will be jeopardized by delay, the Director shall immediately assess such tax or such deficiency and shall mail or issue notice of the finding to the taxpayer together with a demand for immediate payment of such tax or such deficiency declared to be in jeopardy, together with all interest, penalties, additional amounts and additions to the tax provided by law.

(b) In the case of a jeopardy assessment of a tax for a current taxable year or other taxable period, the Director shall determine such tax for the period beginning on the first day of such current taxable year or other taxable period and ending on the date of the Director’s finding under subsection (a) of this section as though such period were a taxable year or other taxable period of the taxpayer.

(c) A jeopardy assessment shall be immediately due and payable, and proceedings for the collection of such assessment may be commenced at once, subject to §§ 554 and 556 of this title. The taxpayer, however, may stay the collection of the whole or any amount of such assessment and prevent such assessment from becoming final by filing with the Director, within 10 days after the date of mailing or issuing the notice of jeopardy assessment, a request for reassessment, accompanied by a bond or, in the discretion of the Director, other adequate security in an amount equal to the amount as to which the stay of collection is sought, conditioned upon the payment of the amount (together with interest thereon) the collection of which is stayed. If a request for reassessment, accompanied by a bond or, in the discretion of the Director, other adequate security in the appropriate amount, is not filed within such 10-day period, the assessment shall become final upon the expiration of such 10-day period.

(d) If a request for reassessment, accompanied by a bond or other adequate security, is filed within the 10-day period provided by subsection (c) of this section, the collection of so much of the amount assessed as is covered by the bond or other security shall be stayed, the Director shall reconsider the assessment and, if the taxpayer has so requested in the request for reassessment, the Director shall grant the taxpayer, or the taxpayer’s authorized representative, an oral hearing. The Director’s determination on the request for reassessment shall become final upon the expiration of 30 days from the date when the Director mails notice of the determination to the taxpayer, unless, within such 30-day period, the taxpayer files with the Tax Appeal Board an application for review of the Director’s determination.

(e) In any proceeding relating to the collection of a jeopardy assessment, the finding of the Director under subsection (a) of this section shall for all purposes be presumptive evidence that the collection of the tax or the assessment or collection of the deficiency was in jeopardy.

(f) The Director may abate the jeopardy assessment if the Director finds that jeopardy does not exist.

68 Del. Laws, c. 187, §  170 Del. Laws, c. 186, §  1

§ 562. Bankruptcy or receivership.

(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.
