(a) Electronic-filing requirements under section 6059. An actuarial report required under
section 6059 with respect to an employee benefit plan must be filed electronically if the filer is required by the Internal Revenue Code or regulations to file at least 10 returns during the calendar year that includes the first day of the plan year. 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. Actuarial reports filed electronically must be made in accordance with the applicable revenue procedures, publications, forms, instructions, or other guidance.
(b) Undue hardship. The Commissioner may waive the requirements of this section in cases of undue economic hardship. One principal factor in determining hardship will be the amount, if any, by which the cost of filing the reports 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, an actuarial report required under 6059) and the period to which it applies.
(c) Failure to file. If a filer required to file an actuarial report under
section 6059 fails to file the report on magnetic media when required to do so by this section, the filer is deemed to have failed to file the report. See
section 6692 for the penalty for the failure to file an actuarial report. In determining whether there is reasonable cause for failure to file the report,
§ 301.6692-1(c) and rules similar to the rules in
§ 301.6724-1(c)(3)(ii) (regarding undue economic hardship related to filing information returns on magnetic media) will apply.
