Code of Federal Regulations Title 26. Internal Revenue § 26.1.1378–1 Taxable year of S corporation

(c) Change in taxable year—(1) Approval required. An S corporation or electing S corporation that wants to change its taxable year must obtain the approval of the Commissioner under section 442 or make an election under section 444. However, an S corporation or electing S corporation may obtain automatic approval for certain changes, including a change to its required taxable year, pursuant to administrative procedures published by the Commissioner.

(2) Short period tax return. An S corporation or electing S corporation that changes its taxable year must make its return for a short period in accordance with section 443, but must not annualize the corporation's taxable income.

(e) Procedures for obtaining approval or making a section 444 election—(1) In general. See § 1.442–1(b) for procedures to obtain the approval of the Commissioner (automatically or otherwise) to adopt, change, or retain a taxable year. See §§ 1.444–1T and 1.444–2T for qualifications, and 1.444–3T for procedures, for making an election under section 444.

(2) Special rules for electing S corporations. An electing S corporation that wants to adopt, change to, or retain a taxable year other than its required taxable year must request approval of the Commissioner on Form 2553, “Election by a Small Business Corporation,” when the election to be an S corporation is filed pursuant to section 1362(b) and § 1.1362–6. See § 1.1362–6(a)(2)(i) for the manner of making an election to be an S corporation. If such corporation receives permission to adopt, change to, or retain a taxable year other than its required taxable year, the election to be an S corporation will be effective. Denial of the request renders the election ineffective unless the corporation agrees that, in the event the request to adopt, change to, or retain a taxable year other than its required taxable year is denied, it will adopt, change to, or retain its required taxable year or, if applicable, make an election under section 444.
