Attorney A provides advice to Client C concerning the proper treatment of an item with respect to which all events have occurred on C's tax return. In preparation for providing that advice, A seeks advice regarding the proper treatment of the item from Attorney B, who is within the same firm as A, but A is the attorney who signs C's return as a tax return preparer. B provides advice on the treatment of the item upon which A relies. B's advice is reflected on C's tax return but no disclosure was made in accordance with § 1.6694-2(d)(3). The advice constitutes preparation of a substantial portion of the return within the meaning of § 301.7701-15(b)(3). The IRS later challenges the position taken on the tax return, giving rise to an understatement of liability. For purposes of the regulations under section 6694, A is initially considered the tax return preparer with respect to C's return, and the IRS advises A that A may be subject to the penalty under section 6694 with respect to C's return. Based upon information received from A or another source, it may be concluded that B, rather than A, had primary responsibility for the position taken on the return that gave rise to the understatement and may be subject to penalty under section 6694 instead of A.
Same as Example 1, except that neither Attorney A nor any other source produce credible information that Attorney B had primary responsibility for the position on the return giving rise to an understatement. Attorney A is the tax return preparer who may be subject to penalty under section 6694 with respect to C's return.
Same as Example 1, except that neither Attorney A nor any other attorney within A's firm signs Client C's return as a tax return preparer. Attorney B is the nonsigning tax return preparer within the firm with overall supervisory responsibility for the position giving rise to an understatement. Accordingly, B is the tax return preparer who is primarily responsible for the position on C's return giving rise to an understatement and may be subject to penalty under section 6694.
Same as Example 1, except Attorney D, who works for a different firm than A, also provides advice on the same position upon which A relies. It may be concluded that D is also primarily responsible for the position on the return and may be subject to penalty under section 6694.
Same as Example 1, except Attorney B is able to present credible information that A is also responsible for the position on C's return giving rise to an understatement. The IRS may conclude between A and B, the two responsible persons for the position, who is primarily responsible and may assess a section 6694 penalty against A or B, but not both, as the primarily responsible tax return preparer.
During an interview conducted by Preparer E, a taxpayer stated that he had made a charitable contribution of real estate in the amount of $50,000 during the tax year, when in fact he had not made this charitable contribution. E did not inquire about the existence of a qualified appraisal or complete a Form 8283, Noncash Charitable Contributions, in accordance with the reporting and substantiation requirements under section 170(f)(11). E reported a deduction on the tax return for the charitable contribution, which resulted in an understatement of liability for tax, and signed the tax return as the tax return preparer. E is subject to a penalty under section 6694.
While preparing the 2008 tax return for an individual taxpayer, Preparer F realizes that the taxpayer did not provide a Form 1099-INT, “Interest Income”, for a bank account that produced significant taxable income in 2007. When F inquired about any other income, the taxpayer furnished the Form 1099-INT to F for use in preparation of the 2008 tax return. F did not know that the taxpayer owned an additional bank account that generated taxable income for 2008, and the taxpayer did not reveal this information to the tax return preparer notwithstanding F's general inquiry about any other income. F signed the taxpayer's return as the tax return preparer. F is not subject to a penalty under section 6694.
In preparing a tax return, for purposes of determining the deductibility of a contribution by an employer for a qualified pension plan, Accountant G relies on a computation of the section 404 limit on deductible amounts made by the enrolled actuary for the plan. On the basis of this calculation, G completed and signed the tax return. It is later determined that there is an understatement of liability for tax that resulted from the overstatement of the section 404 limit on deductible amounts made by the actuary. G had no reason to believe that the actuary's calculation of the limit on deductible contributions was incorrect or incomplete, and the calculation appeared reasonable on its face. G was also not aware at the time the return was prepared of any reason why the actuary did not know all of the relevant facts or that the calculation of the limit on deductible contributions was no longer reliable due to developments in the law since the time the calculation was given. G is not subject to a penalty under section 6694. The actuary, however, may be subject to penalty under section 6694 if the calculation provided by the actuary constitutes a substantial portion of the tax return within the meaning of § 301.7701-15(b)(3) of this chapter.
Signing Tax Return Preparer H is engaged by a taxpayer and paid a total of $21,000. Of this amount, $20,000 relates to research and consultation regarding a transaction that is later reported on a return, and $1,000 is for the activities relating to the preparation of the return. Based on H's hourly rates, a reasonable allocation of the amount of compensation related to the advice rendered prior to the occurrence of events that are the subject of the advice is $5,000. The remaining compensation of $16,000 is considered to be compensation related to the advice rendered after the occurrence of events that are the subject of the advice and return preparation. The income derived by H with respect to the return for purposes of computing the penalty under section 6694(a) is $16,000, and the amount of the penalty imposed under section 6694(a) is $8,000.
Accountants I, J, and K are employed by Firm L. I is a principal manager of Firm L and provides corporate tax advice for the taxpayer after all events have occurred subject to an engagement for corporate tax advice. J provides international tax advice for the taxpayer after all events have occurred subject to a different engagement for international tax advice. K prepares and signs the taxpayer's return under a general tax services engagement. I's advice is the source of an understatement on the return and the advice constitutes preparation of a substantial portion of the return within the meaning of § 301.7701-15(b) of this chapter. I is the nonsigning tax return preparer within the firm with overall supervisory responsibility for the position on the taxpayer's return giving rise to an understatement. Thus, I is the tax return preparer who is primarily responsible for the position on the taxpayer's return giving rise to the understatement. Because K's signature as the signing tax return preparer is on the return, the IRS advises K that K may be subject to the section 6694(a) penalty. K provides credible information that I is the tax return preparer with primary responsibility for the position that gave rise to the understatement. The IRS, therefore, assesses the section 6694 penalty against I. The portion of the total amount of the penalty allocable to I does not exceed 50 percent of that part of I's compensation that is attributable to the corporate tax advice engagement. In the event that Firm L is also liable under the provisions in § 1.6694-2(a)(2), the IRS assesses the section 6694 penalty in an amount not exceeding 50 percent of Firm L's firm compensation based on the engagement relating to the corporate tax advice services provided by I where there is no applicable reduction in compensation pursuant to § 1.6694-1(f)(2)(iii).
Same facts as Example 2, except that I provides the advice on the corporate matter when the events have not yet occurred. I's advice is the cause of an understatement position on the return, but I is not a tax return preparer pursuant to § 301.7701-15(b)(2) or (3) of this chapter. K is not limited to reliance on persons who provide post-transactional advice if such reliance is reasonable and in good faith. Further, K has reasonable cause because K relied on I for the advice on the corporate tax matter. I, K and Firm L are not liable for the section 6694 penalty.
Attorney M is an employee of Firm N with a salary of $75,000 per year. M performs tax preparation work for Client O. Client O's return contains a position that results in an understatement subject to the section 6694 penalty. M spent 100 hours on the position (out of a total 2,000 billed during the year). The total fees earned by Firm N with respect to the position reflected on Client O's return are $50,000. If M is subject to the penalty, the penalty amount computed under the 50 percent of income standard is .5 × (100/2,000) × $75,000 = $1,875. If Firm N is subject to the penalty, the penalty amount computed under the 50% of income standard is .5 × $50,000 = $25,000, less any penalty amount imposed against M. If a penalty of $1,875 was assessed against M and Firm N was subject to the penalty, a penalty of $23,125 would be the amount of penalty assessed against Firm N.
