Delaware Code Title 30. State Taxes § 1154. Information returns and payment of tax withheld

(a) Every employer required to deduct and withhold tax under this chapter shall file a withholding return as prescribed by the Division of Revenue and pay over such tax to the Division of Revenue, or to a depository designated by the Division of Revenue, at a frequency to be determined as follows:

The levels of the applicable thresholds in this subsection are subject to annual adjustment as more fully set forth in § 515 of this title.

(b) The Division of Revenue may modify the filing frequency defined in paragraphs (a)(1)-(3) of this section for any taxpayer, in response to a request from the taxpayer, upon a showing by the taxpayer that they would suffer a hardship if required to comply with the statutory filing frequency.

(c) A quarterly filer shall file a return and pay over taxes required to be deducted and withheld under this chapter not later than the last day of the month following the close of each calendar quarter.

(d) A monthly filer shall, for each month, file a return and pay over taxes required to be deducted and withheld during such month on or before the fifteenth day of the month following the end of such month.

(e) An eighth-monthly filer shall file a return and pay over taxes required to be deducted and withheld under this chapter not later than 3 working days following the end of any deposit or return period during which an employer made any payment subject to a requirement to withhold tax under this chapter.  For purposes of this subsection, each month shall be divided into 8 deposit or return periods.  These deposit or return periods end on the third, seventh, eleventh, fifteenth, nineteenth, twenty-second, twenty-fifth and last day of every month.

(f) For purposes of this subchapter, the term “lookback period” shall refer to the 12-month period between July 1 and June 30 immediately preceding the calendar year for which the filing frequency is determined by reference to the lookback period.

(g) Any employer required under the provisions of § 6302 (or successor provision) of the Internal Revenue Code [26 U.S.C. § 6302] to deposit federal employment taxes by electronic funds transfer shall be required to deposit taxes withheld under this subchapter by electronic funds transfer, except that, for purposes of this subsection, 1 year shall be added to the “applicable effective date” on which deposit by electronic funds transfer is required of a particular employer under regulations promulgated pursuant to the provisions of § 6302 (or successor provision) of the Internal Revenue Code [26 U.S.C. § 6302].  The Director of Revenue shall prescribe such regulations as may be necessary for the development and implementation of an electronic funds transfer system which is required to be used for the collection of taxes withheld under this chapter.  Such system shall be designed in such manner as may be necessary to ensure that such taxes will be credited to an account maintained by the State Treasurer on the date on which the return and taxes would otherwise have been required to be filed under this subchapter.

(h) Any employer that demonstrates it filed and paid over withholding taxes under this chapter on or before the date on which it was required to deposit federal employment taxes shall be deemed to have established reasonable cause for late filing and payment of withheld taxes for purposes of Chapter 5 of this title.

(i) Information returns. -- Any person:

shall also file with the Division of Revenue information returns with respect to each such individual to whom such federal forms are required to be issued.  If a person is required to make and return such information reports to the Internal Revenue Service on magnetic media or in other machine-readable form under Internal Revenue Code § 6011 (26 U.S.C. § 6011) and regulations thereunder or successor provision, then the information returns required to be made under this section shall, unless excepted by the Director, also be made on magnetic media or in other machine-readable form.  All returns required to be filed under this section shall be filed with the Division of Revenue on or before the date on which such returns are required to be filed with the Internal Revenue Service.
