701—52.3 (422) Form for filing.
	 52.3(1) Use and completeness of prescribed forms. Returns shall be made by corporations on forms supplied by the department. Taxpayers not supplied with the proper forms shall make application for same to the department in ample time to have their returns made, verified and filed on or before the due date. Each taxpayer shall carefully prepare the taxpayer’s return so as to fully and clearly set forth the data required. For lack of a prescribed form, a statement made by a taxpayer disclosing the taxpayer’s gross income and the deductions therefrom may be accepted as a tentative return, and if verified and filed within the prescribed time, will relieve the taxpayer from liability to penalties, provided that without unnecessary delay such a tentative return is replaced by a return made on the proper form. Each question shall be answered and each direction complied with in the same manner as if the forms and instructions were embodied in these rules.
Failure to receive the proper forms does not relieve the taxpayer from the obligation of making any return required by the statute.
Returns received which are not completed, but merely state “see schedule attached” are not considered to be a properly filed return and may be returned to the taxpayer for proper completion. This may result in the imposition of penalties and interest due to the return being filed after the due date.
	 52.3(2) Form for filing—domestic corporations. A domestic corporation, as defined by Iowa Code subsection 422.32(5), is required to file a complete Iowa return for each year of its existence regardless of whether the corporation has income, loss, or inactivity. For tax periods beginning on or after January 1, 1999, domestic corporations are required to file a complete Iowa return only if they are doing business in Iowa, or deriving income from sources within Iowa. For tax periods beginning on or after July 1, 2012, domestic corporations must also include a true and accurate copy of their federal corporation income tax return as filed with the Internal Revenue Service with the filing of their Iowa return. At a minimum this return includes the following federal schedules: income statement, balance sheet, reconciliation of income per books with income per return, analysis of unappropriated retained earnings per books, dividend income and special deductions, cost of goods sold, capital gains, tax computation and tax deposits, alternative minimum tax computation, and statements detailing other income and other deductions.
When a domestic corporation is included in the filing of a consolidated federal income tax return, the Iowa corporation income tax return shall include a schedule of the consolidating income statements as properly computed for federal income tax purposes showing the income and expenses of each member of the consolidated group, and a schedule of capital gains on a separate basis.
If a domestic corporation claims a foreign tax credit, research activities credit, alcohol fuel credit, employer social security credit, or work opportunity credit on its federal income tax return, a detailed computation of the credits claimed shall be included with the Iowa return upon filing. In those instances where the domestic corporation is involved in the filing of a consolidated federal income tax return, the credit computations shall be reported on a separate entity basis.
Similarly, where a domestic corporation is charged with a holding company tax or an alternative minimum tax, the details of the taxes levied shall be put forth in a schedule to be included with the Iowa return. Furthermore, these taxes shall be identified on a separate company basis where the domestic corporation files as a member of a consolidated group for federal purposes.
	 52.3(3) Form for filing—foreign corporations. Foreign corporations, as defined by Iowa Code subsection 422.32(6), must include a true and accurate copy of their federal corporation income tax return as filed with the Internal Revenue Service with the filing of their Iowa return. At a minimum this return includes the following federal schedules: income statement, balance sheet, reconciliation of income per books with income per return, analysis of unappropriated retained earnings per books, dividend income and special deductions, cost of goods sold, capital gains, tax computation and tax deposits, research activities credit computation, work opportunity credit computation, foreign tax credit computation, alcohol fuel credit computation, employer social security credit computation, alternative minimum tax computation, and statements detailing other income and other deductions.
When a foreign corporation whose income is included in a consolidated federal income tax return files an Iowa return, federal consolidating income statements as properly computed for federal income tax purposes showing the income and expenses of each member of the consolidated group shall be required together with the following additional schedules on a separate basis:
	  a.   	 Capital gains.
	  b.   	 Dividend income and special deductions.
	  c.   	 Research activities credit, alcohol fuel credit and employer social security credit computations.
	  d.   	 Work opportunity credit computation.
	  e.   	 Foreign tax credit computation.
	  f.   	 Holding company tax computation.
	  g.   	 Alternative minimum tax computation.
	  h.   	 Schedules detailing other income and other deductions.
	 52.3(4) Amended returns. If it becomes known to the taxpayer that the amount of income reported to be federal net income or Iowa taxable income was erroneously stated on the Iowa return, or changed by Internal Revenue Service audit, or otherwise, the taxpayer shall file an amended Iowa return along with supporting schedules, to include the amended federal return and a copy of the federal revenue agent’s report if applicable. A copy of the federal revenue agent’s report and notification of final federal adjustments provided by the taxpayer will be acceptable in lieu of an amended return. The assessment or refund of tax shall be dependent on the statute of limitations as set forth in 701—subrule 51.2(1) and rule 701—55.3(422).
This rule is intended to implement Iowa Code section 422.21 and section 422.36 as amended by 2012 Iowa Acts, Senate File 2328.
