(2) Presumption of due diligence. A tax return preparer will be presumed to have exercised due diligence for purposes of this subdivision if the preparer relies on the work product of another person and the preparer used reasonable care in engaging, supervising, training, and evaluating the person, taking proper account of the nature of the relationship between the preparer and the person.

For purposes of this section, records of the client include all documents or written or electronic materials provided to the tax return preparer, or obtained by the preparer in the course of the preparer’s representation of the client, that preexisted the retention of the preparer by the client. The term also includes materials that were prepared by the client or a third party (not including an employee or agent of the preparer) at any time and provided to the preparer with respect to the subject matter of the representation. The term also includes any return, claim for refund, schedule, affidavit, appraisal or any other document prepared by the preparer, or his or her employee or agent, that was presented to the client with respect to a prior representation if such document is necessary for the taxpayer to comply with his or her current Federal, State or local tax obligations. The term does not include any return, claim for refund, schedule, affidavit, appraisal or any other document prepared by the preparer or the preparer’s firm, employees or agents if the preparer is withholding such document pending the client’s performance of its contractual obligation to pay fees with respect to such document.

Except as provided by paragraph (2) of this subdivision, a tax return preparer shall not prepare a return for a client or represent a client before the department in a matter involving a return prepared by the preparer if the preparer’s involvement in the matter involves a conflict of interest.

(iii) each affected client waives the conflict of interest and gives informed consent, confirmed in writing by each affected client, at the time the existence of the conflict of interest is known by the preparer. The confirmation may be made within a reasonable period of time after the informed consent, but in no event later than 90 days. Copies of the written consents must be retained by the preparer for at least 36 months from the date of the conclusion of the representation of the affected clients, and must be provided to any officer or employee of the department on request.

Any person, whether or not a tax return preparer, who has (or persons who have or share) principal authority and responsibility for overseeing a firm’s practice of preparing tax returns, claims for refunds, or other documents by tax return preparers for submission to the department must take reasonable steps to ensure that the firm has adequate procedures in effect for all members, associates, and employees for purposes of complying with this Part. Any such person who has (or persons who have or share) this principal authority will be subject to discipline for failing to comply with the requirements of this paragraph if:
(ii) the person knows or should know that one or more individuals who are members of, associated with, or employed by, the firm are, or have, engaged in a pattern or practice, in connection with their practice with the firm, that does not comply with this Part, and the person, through willfulness, recklessness, or gross incompetence fails to take prompt action to correct the noncompliance.

(5)
(ii) In the case of an opinion the tax return preparer knows or has reason to know will be used or referred to by a person other than the tax return preparer (or a person who is a member of, associated with, or employed by the tax return preparer’s firm) in promoting, marketing, or recommending to one or more taxpayers a partnership or other entity, investment plan or arrangement a significant purpose of which is the avoidance or evasion of any tax, the department will apply a reasonable tax return preparer standard, considering all facts and circumstances, with emphasis given to the additional risk caused by the tax return preparer’s lack of knowledge of the taxpayer’s particular circumstances, when determining whether a tax return preparer has failed to comply with this subdivision.
(j) Solicitation and advertising.
A tax return preparer may not, with respect to conduct as a tax return preparer, in any way use or participate in the use of any form of public communication or private solicitation containing a false, fraudulent, deceptive, misleading or coercive statement or claim.
(k) Best practices.
Tax return preparers should provide clients with the highest quality representation concerning Federal, State and local tax issues by adhering to best practices in providing advice and in preparing or assisting in the preparation of a submission to the department. The best practices set forth in this subdivision are statements of practices for all tax preparers to aspire to achieve. A violation of a best practice defined in this subdivision will not alone constitute an act of misconduct by the preparer sufficient to support a disciplinary action but such a violation, especially if indicative of a pattern of conduct, may be considered in determining whether a disciplinary rule set forth in the other sections of these standards has been violated. In addition to compliance with the standards of practice provided elsewhere in this Part, best practices include the following:
(a) Knowledge of client’s omission.
A tax return preparer who, having been retained by a client with respect to a matter administered by the department, knows that the client has not complied with the tax and revenue laws of the United States or any state or local government or has made an error in or omission from any return, document, affidavit, or other form which the client submitted or executed under the tax and revenue laws of the United States or any state or local government, must advise the client promptly of the fact of such noncompliance, error, or omission. The preparer must advise the client of the consequences as provided under the applicable Federal, State or local laws and regulations of such noncompliance, error, or omission. A preparer who knows that a return or document that has been prepared for filing contains an error or omission, may not sign, submit or file that return or document with the department, by electronic means or otherwise.
(b) Diligence as to accuracy.
