(a) Tax shelter opinions and offering materials. A practitioner who provides a tax shelter opinion analyzing the Federal tax effects of a tax shelter investment shall comply with each of the following requirements:
(1) Factual matters.
(i) The practitioner must make inquiry as to all relevant facts, be satisfied that the material facts are accurately and completely described in the offering materials, and assure that any representations as to future activities are clearly identified, reasonable and complete.
(ii) A practitioner may not accept as true asserted facts pertaining to the tax shelter which he/she should not, based on his/her background and knowledge, reasonably believe to be true. However, a practitioner need not conduct an audit or independent verification of the asserted facts, or assume that a client's statement of the facts cannot be relied upon, unless he/she has reason to believe that any relevant facts asserted to him/her are untrue.
(iii) If the fair market value of property or the expected financial performance of an investment is relevant to the tax shelter, a practitioner may not accept an appraisal or financial projection as support for the matters claimed therein unless:
(A) The appraisal or financial projection makes sense on its face;
(B) The practitioner reasonably believes that the person making the appraisal or financial projection is competent to do so and is not of dubious reputation; and
(C) The appraisal is based on the definition of fair market value prescribed under the relevant Federal tax provisions.
(iv) If the fair market value of purchased property is to be established by reference to its stated purchase price, the practitioner must examine the terms and conditions upon which the property was (or is to be) purchased to determine whether the stated purchase price reasonably may be considered to be its fair market value.
(2) Relate law to facts. The practitioner must relate the law to the actual facts and, when addressing issues based on future activities, clearly identify what facts are assumed.
(3) Identification of material issues. The practitioner must ascertain that all material Federal tax issues have been considered, and that all of those issues which involve the reasonable possibility of a challenge by the Internal Revenue Service have been fully and fairly addressed in the offering materials.
(4) Opinion on each material issue. Where possible, the practitioner must provide an opinion whether it is more likely than not that an investor will prevail on the merits of each material tax issue presented by the offering which involves a reasonable possibility of a challenge by the Internal Revenue Service. Where such an opinion cannot be given with respect to any material tax issue, the opinion should fully describe the reasons for the practitioner's inability to opine as to the likely outcome.
(5) Overall evaluation.
(i) Where possible, the practitioner must provide an overall evaluation whether the material tax benefits in the aggregate more likely than not will be realized. Where such an overall evaluation cannot be given, the opinion should fully describe the reasons for the practitioner's inability to make an overall evaluation. Opinions concluding that an overall evaluation cannot be provided will be given special scrutiny to determine if the stated reasons are adequate.
(ii) A favorable overall evaluation may not be rendered unless it is based on a conclusion that substantially more than half of the material tax benefits, in terms of their financial impact on a typical investor, more likely than not will be realized if challenged by the Internal Revenue Service.
(iii) If it is not possible to give an overall evaluation, or if the overall evaluation is that the material tax benefits in the aggregate will not be realized, the fact that the practitioner's opinion does not constitute a favorable overall evaluation, or that it is an unfavorable overall evaluation, must be clearly and prominently disclosed in the offering materials.
(iv) The following examples illustrate the principles of this paragraph:

Example (1).

A limited partnership acquires real property in a sale-leaseback transaction. The principal tax benefits offered to investing partners consist of depreciation and interest deductions. Lesser tax benefits are offered to investors by reason of several deductions under Internal Revenue Code section 162 (ordinary and necessary business expenses). If a practitioner concludes that it is more likely than not that the partnership will not be treated as the owner of the property for tax purposes (which is required to allow the interest and depreciation deductions), then he/she may not opine to the effect that it is more likely than not that the material tax benefits in the aggregate will be realized, regardless of whether favorable opinions may be given with respect to the deductions claimed under Code section 162.

Example (2).

A corporation electing under subchapter S of the Internal Revenue Code is formed to engage in research and development activities. The offering materials forecast that deductions for research and experimental expenditures equal to 75% of the total investment in the corporation will be available during the first two years of the corporation's operations, other expenses will account for another 15% of the total investment, and that little or no gross income will be received by the corporation during this period. The practitioner concludes that it is more likely than not that deductions for research and experimental expenditures will be allowable. The practitioner may render an opinion to the effect that based on this conclusion, it is more likely than not that the material tax benefits in the aggregate will be realized, regardless of whether he/she can opine that it is more likely than not that any of the other tax benefits will be achieved.

Example (3).

An investment program is established to acquire offsetting positions in commodities contracts. The objective of the program is to close the loss positions in year one and to close the profit positions in year two. The principal tax benefit offered by the program is a loss in the first year, coupled with the deferral of offsetting gain until the following year. The practitioner concludes that the losses will not be deductible in year one. Accordingly, he/she may not render an opinion to the effect that it is more likely than not that the material tax benefits in the aggregate will be realized, regardless of the fact that he/she is of the opinion that losses not allowable in year one will be allowable in year two, because the principal tax benefit offered is a one-year deferral of income.

Example (4).

A limited partnership is formed to acquire, own and operate residential rental real estate. The offering material forecasts gross income of $2,000,000 and total deductions of $10,000,000, resulting in net losses of $8,000,000 over the first six taxable years. Of the total deductions, depreciation and interest are projected to be $7,000,000, and other deductions $3,000,000. The practitioner concludes that it is more likely than not that all of the depreciation and interest deductions will be allowable, and that it is more likely than not that the other deductions will not be allowed. The practitioner may render an opinion to the efect that it is more likely than not that the material tax benefits in the aggregate will be realized.

(6) Description of opinion. The practitioner must assure that the offering materials correctly and fairly represent the nature and extent of the tax shelter opinion.
(b) Reliance on other opinions—(1) In general. A practitioner may provide an opinion on less than all of the material tax issues only if:
(i) At least one other competent practitioner provides an opinion on the likely outcome with respect to all of the other material tax issues which involve a reasonable possibility of challenge by the Internal Revenue Service, and an overall evalution whether the material tax benefits in the aggregate more likely than not will be realized, which is disseminated in the same manner as the practitioner's opinion; and
(ii) The practitioner, upon reviewing such other opinions and any offering materials, has no reason to believe that the standards of paragraph (a) of this section have not been complied with.
Notwithstanding the foregoing, a practitioner who has not been retained to provide an overall evaluation whether the material tax benefits in the aggregate more likely than not will be realized may issue an opinion on less than all the material tax issues only if he/she has no reason to believe, based on his/her knowledge and experience, that the overall evaluation given by the practitioner who furnishes the overall evaluation is incorrect on its face.
(2) Forecasts and projections. A practitioner who is associated with forecasts or projections relating to or based upon the tax consequences of the tax shelter offering that are included in the offering materials, or are disseminated to potential investors other than the practitioner's clients, may rely on the opinion of another practitioner as to any or all material tax issues, provided that the practitioner who desires to rely on the other opinion has no reason to believe that the standards of paragraph (a) of this section have not been complied with by the practitioner rendering such other opinion, and the requirements of paragraph (b)(1) of this section are satisfied. The practitioner's report shall disclose any material tax issue not covered by, or incorrectly opined upon, by the other opinion, and shall set forth his/her opinion with respect to each such issue in a manner that satisfies the requirements of paragraph (a) of this section.
(c) Definitions. For purposes of this section:
(1) Practitioner includes any individual described in § 10.3(e).
(2) A tax shelter, as the term is used in this section, is an investment which has as a significant and intended feature for Federal income or excise tax purposes either of the following attributes:
(i) Deductions in excess of income from the investment being available in any year to reduce income from other sources in that year, or
(ii) Credits in excess of the tax attributable to the income from the investment being available in any year to offset taxes on income from other sources in that year. Excluded from the term are municipal bonds; annuities; family trusts (but not including schemes or arrangements that are marketed to the public other than in a direct practitioner-client relationship); qualified retirement plans; individual retirement accounts; stock option plans; securities issued in a corporate reorganization; mineral development ventures, if the only tax benefit would be percentage depletion; and real estate where it is anticipated that in no year is it likely that deductions will exceed gross income from the investment in that year, or that tax credits will exceed the tax attributable to gross income from the investment in that year. Whether an investment is intended to have tax shelter features depends on the objective facts and circumstances of each case. Significant weight will be given to the features described in the offering materials to determine whether the investment is a tax shelter.
(3) A tax shelter opinion, as the term is used in this section, is advice by a practitioner concerning the Federal tax aspects of a tax shelter either appearing or referred to in the offering materials, or used or referred to in connection with sales promotion efforts, and directed to persons other than the client who engaged the practitioner to give the advice. The term includes the tax aspects or tax risks portion of the offering materials prepared by or at the direction of a practitioner, whether or not a separate opinion letter is issued or whether or not the practitioner's name is referred to in the offering materials or in connection with the sales promotion efforts. In addition, a financial forcast or projection prepared by a practitioner is a tax shelter opinion if it is predicated on assumptions regarding Federal tax aspects of the investment, and it meets the other requirements of the first sentence of this paragraph. The term does not, however, include rendering advice solely to the offeror or reviewing parts of the offering materials, so long as neither the name of the practitioner, nor the fact that a practitioner has rendered advice concerning the tax aspects, is referred to in the offering materials or in connection with the sales promotion efforts.
(4) A material tax issue as the term is used in this section is
(i) Any Federal income or excise tax issue relating to a tax shelter that would make a significant contribution toward sheltering from Federal taxes income from other sources by providing deductions in excess of the income from the tax shelter investment in any year, or tax credits available to offset tax liabilities in excess of the tax attributable to the tax shelter investment in any year;
(ii) Any other Federal income or excise tax issue relating to a tax shelter that could have a significant impact (either benefical or adverse) on a tax shelter investor under any reasonably foreseeable circumstances (e.g., depreciation or investment tax credit recapture, availability of long-term capital gain treatment, or realization of taxable income in excess of cash flow, upon sale or other disposition of the tax shelter investment); and
(iii) The potential applicability of penalties, additions to tax, or interest charges that reasonably could be asserted against a tax shelter investor by the Internal Revenue Service with respect to the tax shelter. The determination of what is material is to be made in good faith by the practitioner, based on information available at the time the offering materials are circulated.
(d) For purposes of advising the Director of Practice whether an individual may have violated § 10.33, the Director of Practice is authorized to establish an Advisory Committee, composed of at least five individuals authorized to practice before the Internal Revenue Service. Under procedures established by the Director of Practice, such Advisory Committee shall, at the request of the Director of Practice, review and make recommendations with regard to alleged violations of § 10.33.
