Sec. 301.6011-5 Required use of electronic form for corporate income tax returns.

(1) A corporation required to file a corporate income tax return on Form 1120, U.S. Corporation Income Tax Return, under §1.6012-2 of this chapter must file its corporate income tax return electronically if the corporation is required by the Internal Revenue Code or regulations to file at least 10 returns (as defined in paragraph (d)(5) of this section) during the calendar year ending with or within the taxable year of the corporation.

(2) All members of a controlled group of corporations must file their corporate income tax returns electronically if the aggregate number of returns required to be filed by the controlled group of corporations is at least 10 (as defined in paragraph (d)(5) of this section) during the calendar year ending with or within the taxable year of the controlled group of corporations.

(3) The Commissioner may direct the type of electronic filing and may also exempt certain returns from the electronic requirements of this section through revenue procedures, publications, forms, instructions, or other guidance, including postings on the IRS.gov website. Returns filed electronically must be made in accordance with the applicable revenue procedures, publications, forms, instructions, or other guidance.

(1) Waivers. The Commissioner may grant waivers of the requirements of this section in cases of undue hardship. One principal factor in determining hardship will be the amount, if any, by which the cost of filing the return electronically in accordance with this section exceeds the cost of filing the return on paper. A request for a waiver must be made in accordance with applicable IRS revenue procedures, publications, forms, instructions, or other guidance, including postings to the IRS.gov website. The waiver request will specify the type of filing (that is, a return required under §1.6012-2 of this chapter) and the period to which it applies.

(2) Exemptions. The Commissioner may provide exemptions from the requirements of this section to promote effective and efficient tax administration. An exemption will be allowed for filers for whom using the technology required to file in electronic form conflicts with their religious beliefs. A submission claiming an exemption must be made in accordance with applicable IRS revenue procedures, publications, forms, instructions, or other guidance, including postings to the IRS.gov website.

(3) Additional Exclusion. If the IRS’s systems do not support electronic filing, taxpayers will not be required to file electronically.

(1) Magnetic media or electronic form. The terms magnetic media or electronic form mean any media or form permitted under applicable regulations, revenue procedures, or publications. These generally include electronic filing, as well as magnetic tape, tape cartridge, diskette, and other media specifically permitted under the applicable regulations, procedures, publications, forms, instructions, or other guidance.

(2) Corporation. The term corporation means a corporation as defined in section 7701(a)(3).

(3) Controlled group of corporations. The term controlled group of corporations means a group of corporations as defined in section 1563(a).

(4) Corporate income tax return. The term corporate income tax return means a Form 1120, "U.S. Corporation Income Tax Return," along with all other related forms, schedules, and statements that are required to be attached to the Form 1120, and all members of the Form 1120 series of returns, including amended and superseding returns.

(5) Calculating the number of returns. For purposes of this section, a corporation or controlled group of corporations is required to file at least 10 returns if, during the calendar year ending with or within the taxable year of the corporation or the controlled group, the corporation or the controlled group is required to file at least 10 returns of any type, including information returns (for example, Forms W-2 and Forms 1099), income tax returns, employment tax returns, and excise tax returns. In the case of a short-period return, a corporation is required to file at least 10 returns if, during the calendar year in which the corporation’s short taxable year ends, the corporation is required to file at least 10 returns of any type, including information returns (for example, Forms W-2 and Forms 1099), income tax returns, employment tax returns, and excise tax returns. If the corporation is a member of a controlled group, calculating the number of returns the corporation is required to file includes all returns required to be filed by all members of the controlled group during the calendar year ending with or within the taxable year of the controlled group.

(1) The taxable year of Corporation X, a fiscal-year taxpayer, ends on September 30. During the calendar year ending December 31, 2023, X was required to file one Form 1120, U.S. Corporation Income Tax Return, six Forms W-2, Wage and Tax Statement, three Forms 1099-DIV, Dividends and Distributions, one Form 940, Employer's Annual Federal Unemployment (FUTA) Tax Return, and four Forms 941, Employer's Quarterly Federal Tax Return. Because X is required to file 10 returns of any type during calendar year 2023, the calendar year that ended within its taxable year ending September 30, 2024, X is required to file its Form 1120 electronically for its taxable year ending September 30, 2024.
