What this exam covers
5 real sample questions
A practitioner preparing a federal tax filing notices that a client-provided schedule conflicts with a reliable third-party document. Under Circular 230, what is the practitioner's most appropriate response?
A. Make reasonable inquiries and exercise due diligence before relying on the schedule.
B. Use the schedule because clients alone are responsible for factual accuracy.
C. File the return and investigate only if the IRS later selects it for examination.
D. Resolve the conflict by choosing whichever figure produces the smaller tax liability.
Show answer and reasoning

Correct answer: A. Make reasonable inquiries and exercise due diligence before relying on the schedule.

Circular 230 requires due diligence in preparing or assisting with returns and other submissions. A known inconsistency is a reason to inquire; client responsibility does not excuse blind reliance.

  • B: A practitioner may generally rely on client information, but not without inquiry when it appears incorrect, inconsistent, or incomplete.
  • C: Due diligence applies before submission; an audit is not the trigger for investigating a known inconsistency.
  • D: The duty is to determine a supportable fact, not to select the tax-favorable figure.

A CPA represents two taxpayers whose interests directly conflict in the same federal tax matter. Circular 230 permits the representation only if the CPA reasonably believes competent and diligent representation remains possible, the representation is not prohibited by law, and what else occurs?
A. The IRS assigns separate revenue agents to the taxpayers.
B. Each affected client gives informed written consent at the time required by the rule.
C. The clients agree that the CPA will disclose all privileged communications to the IRS.
D. The CPA charges both clients the same fee.
Show answer and reasoning

Correct answer: B. Each affected client gives informed written consent at the time required by the rule.

Circular 230 allows a waivable conflict only when all stated conditions are met, including informed consent confirmed in writing by each affected client. Fee parity and IRS staffing do not cure a conflict.

  • A: Assignment of different IRS personnel does not provide the client consent required by Circular 230.
  • C: Conflict consent does not itself waive privileges or authorize unrestricted disclosure to the IRS.
  • D: Equal fees are irrelevant to whether conflicted representation is permitted.

Under the unamended official text of UCC Article 2, a contract for the sale of goods generally falls within the statute of frauds when the price is at least what amount?
A. $100.
B. $250.
C. $300.
D. $500.
Show answer and reasoning

Correct answer: D. $500.

UCC 2-201 uses a $500 threshold in the official text. This is a fixed statutory element of the rule, not an inflation-indexed annual amount; exceptions and sufficiency requirements must then be considered.

  • A: The official Article 2 text does not set the general threshold at $100.
  • B: The official Article 2 text does not set the general threshold at $250.
  • C: The official Article 2 text does not set the general threshold at $300.

Which engagement is within a Circular 230 exception to the general prohibition on contingent fees for matters before the IRS?
A. Preparing an original income tax return for a percentage of the refund shown.
B. Preparing an amended return before any IRS examination or challenge, for a percentage of the refund.
C. Representing a taxpayer in a judicial proceeding arising under the Internal Revenue Code under a contingent-fee agreement.
D. Giving routine tax-planning advice for a fee equal to a percentage of projected tax savings.
Show answer and reasoning

Correct answer: C. Representing a taxpayer in a judicial proceeding arising under the Internal Revenue Code under a contingent-fee agreement.

Circular 230 expressly permits contingent fees for services connected with a judicial proceeding arising under the Code. Preparing an original return or ordinary planning for a refund- or savings-based fee is outside that exception.

  • A: The rule's general prohibition covers contingent compensation for preparing an original return.
  • B: An amended return is not automatically within an exception merely because it seeks a refund; timing and the specific examination/challenge conditions matter.
  • D: Routine planning is not transformed into an authorized proceeding merely by tying the fee to expected savings.

Under Circular 230, which statement about a practitioner's solicitation of tax clients is correct?
A. A practitioner may use any claim about prior results if the advertisement includes a disclaimer.
B. Direct mail is prohibited even when truthful and otherwise lawful.
C. A practitioner may imply IRS endorsement if the practitioner holds a valid preparer tax identification number.
D. A practitioner may not use false, fraudulent, coercive, or misleading statements or claims.
Show answer and reasoning

Correct answer: D. A practitioner may not use false, fraudulent, coercive, or misleading statements or claims.

Circular 230 regulates the substance of solicitation: false, fraudulent, coercive, and misleading communications are prohibited. A PTIN is not IRS endorsement, and truthful direct mail is not categorically forbidden.

  • A: A disclaimer does not sanitize a false or misleading performance claim.
  • B: The rule permits written solicitation subject to its content and identification requirements; it is not a blanket direct-mail ban.
  • C: Holding a PTIN authorizes identification for filing purposes, not a claim of IRS endorsement.
