26 CFR § 301.6011-5 - Required use of magnetic media for corporate income tax returns.
(a) Corporate income tax returns required on magnetic media - (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 on magnetic media if the corporation is required by the Internal Revenue Code or regulations to file at least 250 returns during the calendar year. Returns filed on magnetic media must be made in accordance with applicable revenue procedures, publications, forms, or instructions. In prescribing revenue procedures, publications, forms, or instructions, the Commissioner may direct the type of magnetic media filing. (See § 601.601(d)(2) of this chapter.)
(2) All members of a controlled group of corporations must file their corporate income tax returns on magnetic media if the aggregate number of returns required to be filed by the controlled group of corporations is at least 250.
(b) Waiver. The Commissioner may grant waivers of the requirements of this section in cases of undue hardship. A request for waiver must be made in accordance with applicable revenue procedures or publications. The waiver also will be subject to the terms and conditions regarding the method of filing as may be prescribed by the Commissioner.
(c) Failure to file. If a corporation fails to file a corporate income tax return on magnetic media when required to do so by this section, the corporation is deemed to have failed to file the return. (See section 6651 for the addition to tax for failure to file a return). In determining whether there is reasonable cause for failure to file the return, § 301.6651-1(c) and rules similar to the rules in § 301.6724-1(c)(3) (undue economic hardship related to filing information returns on magnetic media) will apply.

(See § 601.601(d)(2) of this chapter).
