§ 1.6037-1. Return of electing small business corporation.

¶(a) In general. Every small business corporation (as defined in section 1371(a)) which has made an election under section 1372(a) not to be subject to the tax imposed by chapter 1 of the Code shall file, with respect to each taxable year for which the election is in effect, a return of income on Form 1120-S. The return shall set forth the items of gross income and the deductions allowable in computing taxable income as required by the return form or in the instructions issued with respect thereto and shall be signed in accordance with section 6062 by the person authorized to sign a return. The return shall also set forth the following information concerning the electing small business corporation:

¶(b) Time and place for filing return. The return shall be filed on or before the 15th day of the third month following the close of the taxable year with the internal revenue officer designated in the instructions applicable to Form 1120-S. (See section 6072.)

¶(c) Other provisions. The return on Form 1120-S will be treated as a return filed by the corporation under section 6012, relating to persons required to make returns of income, for purposes of the provisions of chapter 66 of the Code, relating to limitations. Thus, for example, the period of limitation on assessment and collection of any corporate tax found to be due upon a subsequent determination that the corporation was not entitled to the benefits of subchapter S, chapter 1 of the Code, will run from the date of filing the return under section 6037, or from the date prescribed for filing such return, whichever is the later. For the rules requiring the disclosure of certain transactions, see § 1.6011-4T.

¶(d) Penalties. For criminal penalties for failure to file a return, supply information, or pay tax, and for filing a false or fraudulent return, statement, or other document, see sections 7203, 7206, and 7207.
