SECTION 2. BACKGROUND
Internal Revenue Bulletin 1998-46 · 2026-10-03 edition · updated 2026-10-04 · United States
Section 1361(a)(1) of the Internal Revenue Code defines an “S corporation,” with respect to any taxable year, as a small business corporation for which an S corporation election is in effect for that year.
Section 1361(b)(1) defines a “small business corporation” as a domestic corporation that is not an ineligible corporation and that does not (A) have more than 75 shareholders, (B) have as a shareholder a person (other than an estate, a trust described in § 1361(c)(2), or an organization described in § 1361(c)(6)) who is not an individual, (C) have a nonresident alien as a shareholder, and (D) have more than one class of stock.
Section 1362(a)(1) provides that, except in a situation described in § 1362(g), a small business corporation may elect to be treated as an S corporation.
Section 1362(b)(1) provides that the corporation may make an election to be treated as an S corporation (A) at any time during the preceding taxable year, or (B) at any time during the taxable year and on or before the 15th day of the 3rd month of the taxable year. Under § 1362(b)(3), if an S corporation election is made for a taxable year after the 15th day of the 3rd month of that taxable year and on or before the 15th day of the 3rd month of the following taxable year, then the S corporation election is treated as made for the following taxable year.
Section 1362(b)(5) provides that if (A) an election under § 1362(a) is made for any taxable year (determined without regard to § 1362(b)(3)) after the date prescribed by § 1362(b) for making the election for the taxable year or no election is made for any taxable year, and (B) the Secretary determines that there was reasonable cause for the failure to timely make the election, the Secretary may treat the election as timely made for the taxable year (and § 1362(b)(3) shall not apply).
Rev. Proc. 97–40 provides a special procedure to request relief for a late S corporation election. That revenue procedure applies only to a corporation (1) that has not filed a timely S corporation election under § 1362(a)(1), (2) for which an S corporation election is filed within 6 months of the original due date for the election, and (3) for which the due date of the tax return (excluding extensions) for the first year the corporation intended to be an S corporation has not passed.
Rev. Proc. 97–48, 1997–43 I.R.B. 19, provides special procedures to obtain automatic relief for certain late S corporation elections in two situations. In both situations, relief is available only where the due date for the tax return for the first year the corporation intended to be an S corporation has passed and other eligibility requirements are met. Rev. Proc. 97– 48 does not provide relief for late electing small business trust (ESBT), qualified subchapter S trust (QSST), or qualified subchapter S subsidiary (QSub) elections.
Section 1362(f) grants the Service authority to provide relief in situations where a corporation’s S election was not

Section 1361(c)(2)(A)(v) provides that an ESBT (as defined in § 1361(e)) is a permitted S corporation shareholder. Generally, an ESBT is any trust if: (1) the trust does not have as a beneficiary any person other than an individual, an estate, or an organization described in § 170(c)(2), (3), (4), or (5); (2) no interest in the trust was acquired by purchase; and (3) an election to be an ESBT has been filed with respect to the trust.
Section 1361(b)(3)(B) provides that a QSub is a domestic corporation that is not an ineligible corporation, if (1) an S corporation holds 100 percent of the stock of the corporation, and (2) that S corporation elects to treat the subsidiary as a QSub.
Under § 301.9100–1(c) of the Procedure and Administration Regulations, the Commissioner may grant a reasonable extension of time to make a regulatory election or certain statutory elections under all subtitles of the Code, except subtitles E, G, H, and I, if the taxpayer demonstrates to the satisfaction of the Commissioner that the taxpayer acted reasonably and in good faith, and that granting the relief will not prejudice the interests of the Government. Section 301.9100–1(b) defines the term “regulatory election” as an election whose due date is prescribed by a regulation published in the Federal Register, or a revenue ruling, revenue procedure, notice, or announcement published in the Internal Revenue Bulletin.
