Reportable transaction disclosure statement. Disclose information for each reportable transaction in which the corporation participated. Form 8886, Reportable Transaction Disclosure Statement, must be filed for each tax year the corporation participated in the transaction. The corporation may have to pay a penalty if it is required to file Form 8886 and doesn’t do so. The following are reportable transactions.

  1. Any listed transaction that is a transaction that is the same as or substantially similar to one of the types of transactions that the IRS has determined to be a tax avoidance transaction and identified by notice, regulation, or other published guidance as a listed transaction.

  2. Any transaction offered under conditions of confidentiality for which the corporation (or a related party) paid an advisor a fee of at least $50,000.

  3. Certain transactions for which the corporation (or a related party) has contractual protection against disallowance of the tax benefits.

  4. Certain transactions resulting in a loss of at least $2 million in any single year or $4 million in any combination of years.

  5. Any transaction identified by the IRS by notice, regulation, or other published guidance as a “transaction of interest.”

For more information, see Regulations section 1.6011-4. Also see the Instructions for Form 8886.

Penalties. The corporation may have to pay a penalty if it is required to disclose a reportable transaction under section 6011 and fails to properly complete and file Form 8886. Penalties may also apply under section 6707A if the corporation fails to file Form 8886 with its corporate return, fails to provide a copy of Form 8886 to the Office of Tax Shelter Analysis (OTSA), or files a form that fails to include all the information required (or includes incorrect information). Other penalties, such as an accuracy-related penalty under section 6662A, may also apply. See the Instructions for Form 8886 for details on these and other penalties.

Reportable transactions by material advisors. Material advisors to any reportable transaction must disclose certain information about the reportable transaction by filing Form 8918, Material Advisor Disclosure Statement, with the IRS. For details, see the Instructions for Form 8918.

Transfers to a corporation controlled by the transferor. Every significant transferor (as defined in Regulations section 1.351-3(d)) that receives stock of a corporation in exchange for property in a nonrecognition event must include the statement required by Regulations section 1.351-3(a) on or with the transferor’s tax return for the tax year of the exchange. The transferee corporation must include the statement required by Regulations section 1.351-3(b) on or with its return for the tax year of the exchange, unless all the required information is included in any statement(s) provided by a significant transferor that is attached to the same return for the same section 351 exchange.

Election to reduce basis under section 362(e)(2)(C). If property is transferred to a corporation subject to section 362(e) (2), the transferor and the acquiring corporation may elect, under section 362(e)(2)(C), to reduce the transferor’s basis in the stock received instead of reducing the acquiring corporation’s basis in the property transferred. Once made, the election is irrevocable. For more information, see section 362(e)(2) and Regulations section 1.362-4. If an election is made, a statement must be filed in accordance with Regulations section 1.362-4(d)(3).

Regulations section 1.1411-10(g) (section 1411 election with respect to CFCs and QEFs). A corporation that directly or indirectly owns stock of a controlled foreign corporation (CFC) (within the meaning of section 953(c)(1)(B) or section 957(a)) or a passive foreign investment company (within the meaning of section 1297(a)) that the corporation treats as a qualified electing fund (QEF) under section 1293 may make the election provided in Regulations section 1.1411-10(g). The election must be made no later than the first tax year beginning after 2013 during which the corporation (i) includes an amount in gross income for chapter 1 purposes under section 951(a) or section 1293(a) for the CFC or QEF and (ii) has a direct or indirect owner that is subject to tax under section 1411 or would have been if the election were made. This election must be made on an entity-by-entity basis and applies only to the particular CFCs and QEFs for which an election is made. In general, for purposes of section 1411, if an election is in effect for a CFC or QEF, the amounts included in income under section 951 and section 1293 derived from the CFC or QEF are included in net investment income, and distributions described in section 959(d) or section 1293(c) are excluded from net investment income. Additionally, if the corporation elected to be treated as owning stock of a foreign corporation within the meaning of section 958(a) under Proposed Regulations section 1.958-1(e)(2), and an election under Regulations section 1.1411-10(g) is in effect for a CFC, the amount of global intangible low-taxed income included in income under section 951A is included in net investment income to the extent that it is allocated to the CFC under section 951A(f) (2). An election that is made under Regulations section 1.1411-10(g) can’t be revoked. For more information regarding this election, see Regulations section 1.1411-10(g).

The election must be made in a statement that is filed with the corporation’s original or amended return for the tax year in which the election is made. An election can be made on an amended return only if the tax year for which the election is made and all tax years affected by the election aren’t closed by the period of limitations on assessments under section 6501. The statement must include:

  • The name and EIN of the corporation making the election;

  • A declaration that all of its shareholders consent to each election made in the statement;

In addition, for each CFC or QEF held by the corporation for which an election under Regulations section 1.1411-10(g) has already been made by the corporation, the statement should include (i) the name of the CFC or QEF and (ii) either the EIN of the CFC or QEF, or if the CFC or QEF doesn’t have an EIN, the reference ID number of the CFC or QEF.
