Sec. 301.6707A-1 Failure to include on any return or statement any information required to be disclosed under section 6011 with respect to a reportable transaction.

Example 1. Taxpayer T is required to attach a Form 8886 to its return for the 2008 taxable year and to send a copy of the Form 8886 to OTSA at the time it files its return. Taxpayer T fails to attach the Form 8886 to its return and fails to send a copy of the Form 8886 to OTSA. Taxpayer T is subject to a single penalty under section 6707A for failure to disclose because Taxpayer T failed to comply with the disclosure requirements of section 6011 as described in §§ 1.6011-4(d) and 1.6011-4(e) of this chapter. A penalty under section 6707A also would apply if Taxpayer T had failed to comply with only one of the two requirements.

Example 2. Same as Example 1, except that Taxpayer T also subsequently files an amended return for 2008 that reflects Taxpayer T's participation in the reportable transaction described in Example 1. Taxpayer T fails to attach a Form 8886 to the amended return as required by § 1.6011-4(e)(1) of this chapter. Taxpayer T is subject to an additional penalty under section 6707A for failing to disclose a reportable transaction on the amended return for 2008.

Example 3. In November 2009, Taxpayer U participates in a reportable transaction resulting in a loss. On March 15, 2010, Taxpayer U files its 2009 return, on which it reports the loss and to which it fails to attach a Form 8886. One month later, Taxpayer U files an amended return for 2008, on which it carries back the loss and to which it fails to attach a Form 8886. Section 1.6011-4(e)(1) of this chapter requires Taxpayer U to attach a Form 8886 to its amended return for the 2008 taxable year. Taxpayer U is subject to two penalties under section 6707A: one for the failure to attach Form 8886 to its amended return for 2008 and another for the failure to attach Form 8886 to its 2009 return.

Example 4. Taxpayer V participates in a nonlisted reportable transaction and is required to attach a Form 8886 to its return for the 2009 taxable year that is due on March 15, 2010. Taxpayer V timely files its return but fails to attach the Form 8886 to its return. After the due date of Taxpayer V's return and without an extension of time to file, Taxpayer V files an amended return relating to the 2009 taxable year to which Taxpayer V attaches the Form 8886. Taxpayer V is subject to a penalty under section 6707A for failure to disclose because Taxpayer V failed to comply with the disclosure requirements of section 6011 (described in § 1.6011-4(e)(1) of this chapter) by not attaching a Form 8886 to its original return for the 2009 taxable year that was timely filed on or before the due date of March 15, 2010. An additional penalty under section 6707A would apply if Taxpayer V had failed to attach a Form 8886 to its amended return.

Example 5. Shareholder W, a shareholder in an S Corporation, receives a timely Schedule K-1, "Shareholder's Share of Income, Deductions, Credits, etc.," on April 10, 2009, and determines that she is required to attach a Form 8886 to her individual income tax return for the 2008 taxable year. Shareholder W fails to attach the Form 8886 to her 2008 individual income tax return but files a proper and complete Form 8886 with OTSA on June 12, 2009. Section 1.6011-4(e)(1) of this chapter provides that if a taxpayer who is a partner in a partnership, a shareholder in an S corporation, or a beneficiary of a trust receives a timely Schedule K-1 less than 10 calendar days before the due date of the taxpayer's return (including extensions) and, based on receipt of the timely Schedule K-1, the taxpayer determines that the taxpayer participated in a reportable transaction, the disclosure statement will not be considered late if the taxpayer discloses the reportable transaction by filing a disclosure statement with OTSA within 60 calendar days after the due date of the taxpayer's return (including extensions). Accordingly, Shareholder W is not subject to a penalty under section 6707A for failure to disclose.

Example 6. In July 2008, Taxpayer X participates in Transaction Z, a transaction that is not reportable as of April 15, 2009, the date Taxpayer X files his individual income tax return for 2008. On July 15, 2009, Transaction Z is identified as a transaction of interest. Section 1.6011-4(e)(2)(i) of this chapter provides that if a transaction that is not otherwise a reportable transaction becomes a listed transaction or a transaction of interest after the taxpayer has filed a tax return (including an amended return) reflecting the taxpayer's participation in the listed transaction or transaction of interest and before the end of the period of limitations for assessment of tax for any taxable year in which the taxpayer participated in the listed transaction or transaction of interest, then a disclosure statement must be filed with OTSA within 90 calendar days after the date on which the transaction became a listed transaction or transaction of interest, regardless of whether the taxpayer participated in the transaction in the year the transaction became a listed transaction or a transaction of interest. Taxpayer X fails to file a Form 8886 with OTSA by October 13, 2009, 90 calendar days after the date that the transaction was identified as a transaction of interest. Accordingly, Taxpayer X is subject to a penalty under section 6707A.

Example 7. Taxpayer Y is required to attach a Form 8886 to its return for the 2008 taxable year with respect to participation in a listed transaction. Taxpayer Y attaches the Form 8886 to its timely filed return. The Form 8886, however, does not describe all of the potential tax benefits expected to result from this transaction and states that information will be provided upon request. Because the Form 8886 does not describe all of the potential tax benefits expected to result from the transaction and merely provides that the information will be provided upon request, the Form 8886 filed by Taxpayer Y is incomplete and does not satisfy the requirements set forth in § 1.6011-4(d) of this chapter. Taxpayer Y is subject to a penalty under section 6707A for failure to disclose in the appropriate manner.

(i) In general--

(ii) Subsequently identified transactions. If the taxpayer fails to file, as required by §1.6011-4(a) of this chapter, a complete and proper disclosure statement disclosing participation in a listed transaction or transaction of interest with respect to more than one return in the time prescribed under §1.6011-4(e)(2)(i) of this chapter, the amount of the penalty will be computed by aggregating the decrease in tax shown on each return for which the period of limitations on assessment remains open.

(iii) Penalty for failure to report to the SEC. In the case of a penalty imposed under section 6707A(e) for failure to disclose liability for certain penalties in reports to the Securities and Exchange Commission (SEC), the amount of the penalty will be determined under section 6707A(b) and this paragraph (d), regardless of whether the penalty that the taxpayer failed to disclose is imposed under section 6707A, 6662A, or 6662(h).

(iv) Minimum and maximum amount of the penalty. The limitations on the minimum and maximum penalty amounts described in paragraph (a) of this section apply separately to each failure to disclose that is subject to a penalty.

(i) Example 1. Taxpayer X, a natural person, participated in a listed transaction involving a Roth IRA and filed a return reflecting participation in the transaction. X failed to disclose participation in the listed transaction as required by the regulations under section 6011. As a result of the transaction, X was liable under section 4973 for a $10,000 excise tax for excess contributions to X’s Roth IRA. On X’s return reflecting participation in the listed transaction, X correctly reported $25,000 of income tax, none of which was attributable to the listed transaction, but failed to report the excise tax. If X had not participated in the listed transaction, the excise tax under section 4973 would not have applied and X’s income tax would have remained $25,000. There would, therefore, be no difference between the tax on the return as filed and the tax on the return if it did not reflect participation in the transaction. The excise tax, however, is another tax that resulted from participation in the transaction but was not reported on X’s return, as described in paragraph (d)(1)(i)(B) of this section. Therefore, under paragraph (d)(1) of this section, the decrease in tax resulting from the listed transaction is $10,000. This amount is determined by adding zero (the excess of the amount of tax that would have been shown on X’s return if the return did not reflect X’s participation in the transaction over the tax X actually reported on the return reflecting X’s participation in the transaction) and $10,000 (the amount of excise tax that resulted from participation in the transaction but was not reported on the return). The amount of the penalty under section 6707A is $7,500, which amount is 75 percent of the $10,000 decrease in tax.

(ii) Example 2. Taxpayer X participated in a listed transaction that resulted in a $40,000 decrease in the tax shown on the return reflecting participation in the transaction. X failed to disclose its participation in the transaction as required by the regulations under section 6011 and is, therefore, subject to a penalty under section 6707A. After weighing litigating hazards and other costs of litigation, the IRS Office of Appeals agreed to settle X’s deficiency for $20,000. For purposes of calculating the amount of the penalty under paragraph (d)(1) of this section, the settlement does not affect the decrease in tax shown on X’s return as a result of the listed transaction which remains $40,000. The amount of X’s penalty under section 6707A is $30,000, which amount is 75 percent of the $40,000 decrease in tax.

(iii) Example 3. For the 2018 tax year, Taxpayer X, a natural person, failed to disclose participation in a reportable transaction that is not a listed transaction and, therefore, is subject to a penalty under section 6707A. After offsetting gross income with the losses generated in the reportable transaction, X’s return reported adjusted gross income of $100,000. The return also reported $12,000 of medical expenses, $4,500 of which were deductible after applying the 7.5 percent floor in section 213(a) and (f). If X’s return had not reflected participation in the reportable transaction, X’s adjusted gross income would have been $140,000 and the deductible medical expenses would be limited to $1,500 ($3,000 less than the deductible amount claimed). Under paragraph (d)(1) of this section, the decrease in tax shown on X’s return as a result of X’s participation in the reportable transaction takes into account both the tax on the additional $40,000 in adjusted gross income had X not participated in the reportable transaction and the tax on the $3,000 adjustment to X’s deductible medical expenses caused by the increase in adjusted gross income.

(iv) Example 4. Taxpayer X, a natural person, timely filed X’s 2019 return and reported income tax of $40,000. X did not participate in a reportable transaction in 2019. X participated in a listed transaction in 2020, but failed to file a complete and proper disclosure statement with X’s 2020 return as required by the regulations under section 6011. As filed, the 2020 return reports that X owes no tax and has a loss of $10,000. If the tax consequences of the listed transaction were not reflected on the 2020 return, the return would show income tax of $15,000 and no loss. X files an amended return for the 2019 tax year on which the only amendment is to carry back the $10,000 loss reported on the 2020 tax return to the 2019 tax year. The loss carryback reduces X’s tax liability for 2019 by $3,000 to $37,000. X fails to file a complete and proper disclosure statement with the 2019 amended return as required by the regulations under section 6011. Two penalties under section 6707A apply: one for X’s failure to disclose participation in a listed transaction reflected on the 2020 return and another for the failure to disclose participation in the same listed transaction reflected on the 2019 amended return. Under paragraph (d)(1) of this section, the decrease in tax on the 2020 return resulting from the listed transaction is $15,000, which is the excess of the amount of tax that would have been shown on X’s 2020 return if that return did not reflect X’s participation in the listed transaction over the tax X actually reported on the 2020 return. The amount of the section 6707A penalty with respect to the 2020 return is $11,250, which amount is 75 percent of the decrease in tax. Under paragraph (d)(1) of this section, the decrease in tax on the 2019 amended return that results from the listed transaction is $3,000. This amount is computed by determining the excess of the amount of tax that would have been shown on X’s 2019 amended return if that return did not reflect X’s participation in the listed transaction over the tax X actually reported on the 2019 amended return reflecting the loss carryback resulting from X’s participation in the listed transaction in 2020. See paragraph (c) of this section. However, because X is a natural person, and because 75 percent of the $3,000 decrease in tax is less than $5,000, which is the minimum penalty under paragraph (a) of this section and section 6707A(b)(3), the section 6707A penalty with respect to the failure to disclose the listed transaction with respect to the 2019 amended return is $5,000. Accordingly, X is subject to a $11,250 section 6707A penalty for failure to disclose participation in a listed transaction reflected on the 2020 return and a $5,000 section 6707A penalty for failure to disclose participation in a listed transaction reflected on the 2019 amended return.

(v) Example 5. Taxpayer X, a corporation, timely files its 2019, 2020, and 2021 returns, each of which reflects participation in the same transaction. In 2023, the transaction becomes a listed transaction. When the transaction at issue became listed, the periods of limitations on assessment on X’s 2020 and 2021 tax year were open, but the period of limitations on assessment on X’s 2019 tax year was closed. Pursuant to §1.6011-4(a) and (e)(2)(i) of this chapter, X is required to file a single disclosure statement reflecting its participation in the listed transaction 90 calendar days after the date on which the transaction becomes a listed transaction. X failed to file a disclosure statement as required. Pursuant to paragraph (d)(1)(ii) of this section, the section 6707A penalty is computed by aggregating the decrease in tax shown on the 2020 return and the decrease in tax shown on the 2021 return. Because the period of limitations on assessment for X’s 2019 tax year was closed at the time the transaction became listed, the decrease in tax shown on the 2019 return as a result of X’s participation in the listed transaction is not taken into account in computing the amount of the penalty. The decreases in tax shown on the returns as a result of X’s participation in the transaction are $265,000 in tax year 2020 and $7,000 in tax year 2021. Under paragraph (d)(1) of this section, the total decrease in tax shown is computed by adding the decrease in tax for 2020 and the decrease in tax for 2021, which is $272,000. Seventy-five percent of that amount is $204,000. Because X is a corporation, the maximum penalty amount is$200,000 under paragraph (a) of this section and section 6707A(b)(2)(A). Accordingly, X is subject to a section 6707A penalty of $200,000, rather than $204,000.

(vi) Example 6. Taxpayer X, a natural person, files X’s 2019 return reflecting participation in a reportable transaction that is not a listed transaction, but fails to disclose the transaction as required by the regulations under section 6011. The decrease in tax with respect to X’s 2019 return as a result of participation in the reportable transaction is $20,000. X files an amended 2019 return to include a net operating loss carried forward from a prior year, which X inadvertently failed to include when filing the original 2019 return. The amended return reflects participation in the same reportable transaction, but X again fails to disclose the transaction as required by the regulations under section 6011. The decrease in tax with respect to the amended 2019 return as a result of participation in the transaction is also $20,000. X is subject to two separate 6707A penalties: one for the failure to disclose the reportable transaction with respect to the tax benefits from the reportable transaction reflected on the original 2019 return and one for the failure to disclose the reportable transaction with respect to the tax benefits from the reportable transaction reflected on the amended 2019 return. Seventy-five percent of the $20,000 decrease in tax shown on the original 2019 return is $15,000 and on the amended 2019 return is another $15,000. However, because X is a natural person, the amount of the penalty for failure to disclose is limited to the maximum amount of $10,000 under §301.6707A-1(a) and section 6707A(b)(2)(B). Accordingly, the amount of the section 6707A penalty for the 2019 original return is $10,000 and the amount of the section 6707A penalty for the 2019 amended return is also $10,000, for a total penalty of $20,000.

(vii) Example 7. Taxpayer X, a natural person, timely files X’s 2019 return on April 15, 2020, reflecting participation in a transaction that was not identified as a reportable transaction when X filed the return, the only year X participated in the transaction. In early 2021, the IRS identifies the transaction as a listed transaction. X fails to disclose the listed transaction as required by the regulations under section 6011. In late 2021, X files an amended 2019 income tax return to claim deductions that had been omitted from the originally filed 2019 return. The amended 2019 return reflects X’s participation in the listed transaction. X does not disclose the listed transaction when filing the amended 2019 return. The decrease in tax resulting from X’s participation in the transaction is $100,000 with respect to the original 2019 return and $80,000 with respect to the 2019 amended return. Pursuant to §1.6011-4(e)(2)(i) of this chapter, X was required to file a disclosure statement reflecting X’s participation in the listed transaction if the period of limitations on assessment of tax remained open for any taxable year in which the taxpayer participated in the listed transaction. When the transaction at issue became listed, the period of limitations on assessment on X’s 2019 tax year was open. Pursuant to §1.6011-4(e)(1) of this chapter, X was also required to disclose participation in the transaction when the 2019 amended return was filed because the transaction was a listed transaction at that time. X is subject to two penalties under section 6707A: one for the failure to disclose participation in a listed transaction reflected on X’s original 2019 return within 90 calendar days of the date the transaction became a listed transaction as required by §1.6011-4(e)(2)(i) of this chapter and another for the failure to disclose participation in the same listed transaction reflected on the 2019 amended return. Seventy-five percent of this decrease in tax with respect to the original 2019 return is $75,000 (75 percent of $100,000) and with respect to the 2019 amended return is $60,000 (75 percent of $80,000). Pursuant to paragraph (d)(1)(iv) of this section, because X is subject to two separate penalties, the maximum penalty amount of $100,000 under §301.6707A-1(a) and section 6707A(b)(2)(A) applies separately to each penalty and does not operate to reduce the amount of the X’s 6707A penalties.

(viii) Example 8. Under §1.6011-4 of this chapter, Partnership M is required to attach a disclosure statement to its Form 1065, U.S. Return of Partnership Income, for the 2020 taxable year. M fails to do so and is, therefore, subject to a penalty under section 6707A. No tax is required to be shown on M’s Form 1065. Pursuant to §301.6707A-1(d)(2), M is subject to the minimum section 6707A penalty of $10,000. The partners of Partnership M may have separate disclosure obligations as required by the regulations under section 6011 and would be subject to separate section 6707A penalties if they fail to comply with the disclosure requirements.

(ix) Example 9. In tax year 2019, Taxpayer X participated in a listed transaction that resulted in a $150,000 deduction. X’s gross income for 2019 before the listed transaction deduction is $100,000. X uses $100,000 of the deduction resulting in zero tax liability for 2019. X carried over to tax year 2020 the remaining $50,000 net operating loss that was not used in 2019. X’s gross income for tax year 2020 is $200,000 but as a result of the $50,000 net operating loss carryover, X reports $150,000 adjusted gross income. Pursuant to §1.6011-4 of this chapter, X is required to disclose participation in the listed transaction for both 2019 and 2020, but X fails to make the required disclosures and is therefore subject to the section 6707A penalty for each failure. The decrease in tax on the 2019 return is the amount of tax on $100,000 because that is the difference between the amount of tax that would have been shown on the return if it did not reflect participation in the listed transaction and the tax actually reported. No other tax resulted from X’s participation in the listed transaction. The amount of the penalty with respect to X’s failure to disclose with respect to 2019 will be 75 percent of the decrease in tax. The decrease in tax on the 2020 return is the difference between the tax shown on the return as filed and the tax that would be shown if the $50,000 net operating loss was not used, including any changes to the amount of tax that are only indirectly connected with the listed transaction. The amount of the penalty with respect to X’s failure to disclose with respect to 2020 will be 75 percent of the decrease in tax, subject to the minimum and maximum penalty amount limitations.

(x) Example 10. In tax year 2020, Taxpayer X, a natural person, participated in a listed transaction that resulted in a $50,000 deduction. X also has a net operating loss carryover of $150,000 from 2019. X uses the deduction of $50,000 and a portion of the net operating loss carryover resulting in zero tax liability for 2020. X carries over the remaining net operating loss to tax year 2021. X’s gross income for 2021 is $250,000, but as a result of the net operating loss carryover, X reports reduced adjusted gross income of $150,000. Pursuant to §1.6011-4 of this chapter, X is required to disclose participation in the listed transaction for both 2020 and 2021, but X fails to make the required disclosures and is subject to the section 6707A penalty for each failure. The decrease in tax on the 2020 return that results from the reportable transaction is zero. Because X has $150,000 of a net operating loss carryover not attributable to the reportable transaction, X’s tax without the benefits of the reportable transaction is the same as the tax shown on the 2020 return as filed. Because X is a natural person, the minimum penalty of $5,000 under §301.6707A-1(a) and section 6707A(b)(3) will apply for the failure to disclose the listed transaction with the 2020 return. The decrease in tax on the 2021 return is the difference between the tax shown on the return as filed and the tax that would be shown if X had only $50,000 of net operating loss to carry over to 2021 (i.e., if X had not offset $50,000 of its 2020 gross income with the deduction resulting from the reportable transaction and thus had used $100,000 of its net operating loss carryover in 2020), including any changes to the amount of tax that are only indirectly connected with the listed transaction. The amount of the penalty with respect to the disclosure relating to 2021 will be 75 percent of this decrease in tax, subject to the minimum and maximum penalty amount limitations.

(xi) Example 11. Taxpayer X, a public corporation required to file periodic reports under section 13 or 15(d) of the Securities Exchange Act of 1934, timely filed its 2019 return reflecting tax benefits from a reportable transaction that is not a listed transaction and properly disclosed the transaction in accordance with the regulations under section 6011. In 2023, as a result of an examination of X’s 2019 return, the IRS imposes a penalty under section 6662A with respect to the reportable transaction. The decrease in tax for purposes of paragraph (d)(1) of this section is $190,000. As a person who is required to file periodic reports under section 13 or 15(d) of the Securities Exchange Act of 1934, X is required, pursuant to section 6707A(e), to disclose the penalty imposed under section 6662A to the Securities and Exchange Commission in 2023, which X failed to do. X’s failure to disclose the section 6662A penalty is treated as a failure to disclose to which section 6707A(b) applies. Thus, X is subject to a penalty under section 6707A(e), which equals 75 percent of the decrease in tax resulting from the transaction. The decrease in tax resulting from the reportable transaction was $190,000, 75 percent of which is $142,500. Because X is a corporation and the transaction is not a listed transaction, the amount of the penalty is limited to $50,000 under paragraph (a) of this section and section 6707A(b)(2)(B). Therefore, rather than $142,500, X is subject to a $50,000 section 6707A penalty for failure to disclose the section 6662A penalty to the SEC.

(i) The violation relates to a reportable transaction that is not a listed transaction; and

(ii) Rescinding the penalty would promote compliance with the requirements of the Code and effective tax administration.

(i) The taxpayer, upon becoming aware that it failed, in whole or in part, to disclose a reportable transaction in accordance with the requirements of § 1.6011-4 of this chapter, filed a complete and proper, albeit untimely, Form 8886 (or successor form), as required by § 1.6011-4. If the penalty is due to the taxpayer's failure to file Form 8886 (or successor form) with a return, in order for an untimely disclosure to weigh in favor of rescission, the taxpayer must file an amended return with the appropriate Service Center and attach a complete and proper Form 8886 (or successor form) to that amended return. The amended return filed with the untimely Form 8886 (or successor form) must not reflect any other changes to the return that it amends, and the taxpayer must, in the space provided for an explanation of changes on the amended return, state the reason for filing the amended return. If the penalty is due to the taxpayer's failure to file Form 8886 (or successor form) with OTSA, in order for an untimely disclosure to weigh in favor of rescission, the taxpayer must file a complete and proper Form 8886 (or successor form) with OTSA. If the taxpayer fails to file a complete and proper Form 8886 (or successor form) with the return and also fails to file a copy of the complete and proper Form 8886 (or successor form) with OTSA, incurring one penalty for both failures, then the taxpayer must, in the manner prescribed in this paragraph (e)(3)(i), file complete and proper Forms 8886 with both the Service Center and OTSA in order for the untimely disclosures to weigh in favor of rescission. This factor will weigh heavily in favor of rescission provided that --

(ii) The failure, in whole or in part, to disclose in accordance with the requirements of § 1.6011-4 of this chapter was due to an unintentional mistake of fact that existed despite the taxpayer's reasonable attempts to ascertain the correct facts with respect to the transaction.

(iii) The taxpayer has an established history of properly disclosing other reportable transactions and complying with other tax laws.

(iv) The taxpayer demonstrates that the failure to include on any return or statement any information required to be disclosed under section 6011 arose from events beyond the taxpayer's control.

(v) The taxpayer cooperates with the IRS by providing timely information with respect to the transaction at issue that the Commissioner (or the Commissioner's delegate) may request in consideration of the rescission request. In considering whether a taxpayer cooperates with the IRS, the Commissioner (or the Commissioner's delegate) will take into account whether the taxpayer meets the deadlines described in Rev. Proc. 2007-21 (2007-1 CB 613) (or successor document) (see § 601.601(d)(2)(ii)(b) of this chapter) for complying with requests for additional information.

(vi) Assessment of the penalty weighs against equity and good conscience, including whether the taxpayer demonstrates that there was reasonable cause for, and the taxpayer acted in good faith with respect to, the failure to timely file or to include on any return any information required to be disclosed under section 6011. An important factor in determining reasonable cause and good faith is the extent of the taxpayer's efforts to ensure that persons who prepared the taxpayer's return were informed of the taxpayer's participation in the reportable transactions; this factor will be disregarded, however, if the persons who prepared the taxpayer's return were material advisors with respect to the reportable transaction. The presence of reasonable cause, however, will not necessarily be determinative of whether to grant rescission.

Example. In 2008, Taxpayer Z participated in a nonlisted reportable transaction for the first time. Under § 1.6011-4(e)(1) of this chapter, he was required to attach a complete and proper Form 8886 to his 2008 return, due on April 15, 2009, and to file a copy of the Form 8886 with OTSA. Taxpayer Z timely filed his 2008 return but failed to attach a Form 8886 to his return or file a Form 8886 with OTSA. On June 1, 2009, Taxpayer Z discovered his error. On June 8, 2009, Taxpayer Z filed an amended return for tax year 2008 and attached a complete and proper Form 8886 that disclosed his participation in the reportable transaction. The amended return reflected no changes from the original return and explained that the sole purpose of the amended return was to correct Taxpayer Z's failure to file a Form 8886 with his original return. On June 8, 2009, Taxpayer Z also filed a copy of the complete and proper Form 8886 with OTSA. The IRS later notified Taxpayer Z that he was subject to a penalty under section 6707A because he failed to comply with the disclosure requirements of section 6011 by not attaching Form 8886 to his return for the 2008 taxable year. The IRS properly assessed the penalty under section 6707A and, on October 15, 2010, issued notice and demand. On November 1, 2010, in accordance with Rev. Proc. 2007-21, Taxpayer Z submitted a written request for rescission of the assessed penalty. The fact that Taxpayer Z filed an untimely Form 8886 shortly after discovery of his error but before the IRS first contacted him concerning his return for the 2008 taxable year will weigh heavily in favor of rescission.

(i) The penalty imposed by section 6707A(a) for failure to disclose a listed transaction.

(ii) The accuracy-related penalty imposed by section 6662A(a) at the 30-percent rate determined under section 6662A(c) for a reportable transaction understatement with respect to which the relevant facts affecting the tax treatment of the reportable transaction were not adequately disclosed in accordance with regulations prescribed under section 6011.

(iii) The accuracy-related penalty imposed by section 6662(a) at the 40-percent rate determined under section 6662(h) for a gross valuation misstatement, if the taxpayer (but for the exclusionary rule of section 6662A(e)(2)(C)(ii)) would have been subject to the accuracy-related penalty under section 6662A(a) at the 30-percent rate determined under section 6662A(c).

(iv) The penalty described in paragraph (f)(3) of this section for failure to disclose in periodic reports filed with the SEC the requirement to pay any of the penalties described in paragraphs (f)(1)(i) through (f)(1)(iii) or paragraph (f)(3) of this section.
