Under Circular 230, which of the following constitutes 'practice before the IRS'?
Providing general tax planning advice to clients without making representations directly to the IRS
Preparing financial statements that will support a tax filing
Representing a taxpayer in an IRS audit and communicating with IRS agents on the taxpayer's behalf
Preparing and signing a federal tax return as a paid return preparer
Explanation
Practice before the IRS includes all matters connected with a presentation to the IRS relating to a taxpayer's rights, privileges, or liabilities, including representing a taxpayer before IRS personnel and communicating with IRS agents. Representing a client in an audit is the clearest form of IRS practice. Option A is incorrect; return preparation alone does not constitute practice before the IRS under the Circular 230 definition. Options C and D do not involve direct representation before the IRS.
Under Circular 230, when a conflict of interest exists, what must a practitioner do to continue the representation?
Continue because all conflicts are waivable and consent is presumed when fees are paid
Obtain informed written consent from each affected client after full disclosure of the conflict, and proceed only if each client gives written consent
Immediately withdraw from all conflicted engagements without exception
Disclose the conflict only if the IRS independently requests disclosure
Explanation
Circular 230 Section 10.29(b) permits a practitioner to represent a client despite a conflict if: (1) the practitioner reasonably believes the representation of each affected client will not be adversely affected; (2) each client waives the conflict and gives informed written consent; and (3) the consent is confirmed in writing. The consent must be informed - meaning the conflict is fully explained - and it must be in writing. Option A overstates the restriction by prohibiting all conflicted engagements even when waiver is possible. Option B eliminates the need for consent. Option C applies a much weaker standard than Circular 230 requires.
Under Circular 230 Section 10.22, what are a practitioner's due diligence obligations?
The practitioner must exercise due diligence in preparing and filing documents, and must make reasonable inquiries when information appears incorrect, inconsistent, or incomplete
The practitioner must conduct background investigations on new clients before accepting any engagement
The practitioner must independently audit and verify all information provided by clients before submitting documents to the IRS
The practitioner must perform audit procedures on client records to ensure accuracy of all factual representations
Explanation
Section 10.22 requires practitioners to exercise due diligence in: preparing returns and documents; determining the correctness of oral and written representations to Treasury and the IRS; and making reasonable inquiries when information appears incorrect or inconsistent. This is a professional standard of care, not an audit obligation. Option B imposes audit-level verification not required by Circular 230. Options C and D are not part of the due diligence requirements under Circular 230.
A CPA charges a contingent fee equal to 20% of refunds obtained for clients filing amended returns. Under Circular 230, when is this permissible?
Never; contingent fees are prohibited for all return-related services under Circular 230
When the fee is agreed to in writing before the amended return is filed
Only for amended returns filed because of IRS examination of or challenge to the original return; contingent fees on amended returns filed solely to generate a refund unrelated to IRS action are prohibited
Always; contingent fees are always permissible for amended return preparation
Explanation
Circular 230 Section 10.27 creates a specific exception for amended returns: contingent fees are permissible for an amended return or refund claim filed solely in connection with the determination of statutory interest or penalties assessed by the IRS or in response to an IRS examination, notice, or challenge. However, charging contingent fees for amended returns filed proactively - not in response to IRS action - to generate refunds is prohibited. Option A incorrectly makes contingent fees always permissible. Option B adds a written agreement condition that is not the controlling factor. Option D overstates the prohibition.
A CPA representing a taxpayer in an IRS audit discovers that the taxpayer's prior-year return contains a material error. Under Circular 230 Section 10.21, what must the CPA do?
Withdraw from the engagement immediately without advising the client of the reason for withdrawal
Immediately notify the IRS of the error before proceeding with the current audit representation
Include the error details in the current audit response to ensure the IRS has complete information
Promptly advise the client of the error and the potential consequences; the CPA may not notify the IRS without client consent unless otherwise required by law
Explanation
Circular 230 Section 10.21 requires a practitioner who knows of a client's noncompliance with revenue laws to promptly advise the client of the noncompliance and potential consequences. The practitioner does not have authority to unilaterally notify the IRS; client confidentiality and the attorney-client privilege protect this information from disclosure without consent. Option B requires IRS notification without consent, violating confidentiality. Option C requires withdrawal without advising the client, which fails the Section 10.21 notification obligation. Option D could harm the client by volunteering information in an audit context.
Under Circular 230 Section 10.37, a practitioner providing written tax advice must do which of the following?
Include a disclaimer in every written advice stating that the IRS has not reviewed or approved the positions
Format all written advice as a formal covered opinion regardless of the transaction's complexity
Base advice on reasonable factual and legal assumptions, not rely on unreasonable or false representations, and identify significant assumptions and key limitations on the advice
Submit the written advice to the IRS for review before delivering it to the client
Explanation
Section 10.37 sets out the requirements for written advice: it must be based on reasonable factual and legal assumptions; the practitioner may not rely on representations that the practitioner knows or should know are unreasonable; the advice must identify any significant assumptions made; and it should not contain false statements or mislead the client about the certainty of outcomes. Answer D is correct. Option A has no basis in Circular 230. Option B is incorrect; formal covered opinion requirements apply only to specific types of transactions. Option C is not a Circular 230 requirement.
A CPA supervises junior staff who prepared a return with a material error resulting from inadequate review. The CPA signed the return without examining it. Which statement about supervisory responsibility under Circular 230 is correct?
The practitioner's supervisory obligation is limited to mathematical accuracy checks
Practitioners must take reasonable steps to ensure supervised individuals comply with Circular 230; signing without adequate review when supervision was deficient may constitute the practitioner's own Circular 230 violation
The supervising practitioner has no Circular 230 liability for errors made by supervised staff
Circular 230 supervisory obligations apply only to managing partners, not to individual signing practitioners
Explanation
Circular 230 Section 10.36 imposes responsibility on a supervising practitioner to take reasonable steps to ensure that supervised associates comply with Circular 230. Signing a return without appropriate review, when the CPA has not established adequate supervisory procedures, may itself be a violation. The signing practitioner takes responsibility for the positions on the return. Options B, C, and D each narrow or eliminate supervisory responsibility in ways inconsistent with Section 10.36.
A practitioner charges a contingent fee equal to 30% of any IRS refund obtained for clients filing original income tax returns. The practitioner argues this structure is disclosed in writing and aligns incentives. Which Circular 230 analysis is most accurate?
The fee structure is permissible because contingent fees may always be used for refund-generating work
The fee structure violates Circular 230 Section 10.27; contingent fees are specifically prohibited for preparing original tax returns because tying the fee to a refund creates an incentive to overstate deductions and underreport income, regardless of written disclosure
The fee structure is permissible because it is disclosed to clients in writing
The fee structure is permissible if the contingent percentage does not exceed 25%
Explanation
Section 10.27 prohibits contingent fees for preparation of original tax returns. This prohibition is absolute - written disclosure to the client and alignment of interests are not defenses. The policy concern is that when the practitioner's fee depends on the size of the refund, there is a structural incentive to inflate deductions or aggressively interpret income exclusions, undermining the integrity of the tax system. Option A is incorrect; disclosure does not overcome the prohibition. Option B broadly permits contingent fees for refund work, which is not the rule. Option D invents a percentage threshold.
A CPA represents two competing businesses in separate IRS employment tax audits involving the same worker classification legal issue. A favorable ruling for one client could set adverse precedent for the other. The conflict was not disclosed to either client. Which Circular 230 analysis is most complete?
The representation is permissible because the audits are factually separate even though they share a legal issue
The CPA violated Circular 230; representing both clients in audits involving the same legal theory where a favorable outcome for one may create adverse precedent for the other constitutes a significant risk of materially limiting each client's representation, requiring disclosure and written consent that was never obtained
The representation is permissible because the clients are in separate industries
The representation is permissible if the CPA advocates the same legal position for both clients
Explanation
Even when the underlying facts differ, representing two clients whose legal interests are adverse - one client's favorable ruling could harm the other's position - creates a conflict of interest under Section 10.29. The CPA faces a structural incentive to argue more aggressively for one client at the expense of the other, or to avoid arguments that would help one but hurt the other. The failure to disclose and obtain written consent makes this a clear violation. Options A, B, and C each rationalize the conflict away without applying the Section 10.29 standard.
During an IRS audit, the IRS requests documents belonging to a client. The client instructs the CPA not to produce the documents. Under Circular 230, which analysis is most accurate?
The CPA must advise the client of legal obligations and consequences of withholding documents; the CPA may not assist in improperly obstructing IRS access to legitimately requested information but must respect legally privileged communications and the client's right to assert legal defenses
The CPA must withdraw from the engagement immediately upon receiving the withholding instruction
The CPA must produce all requested documents immediately regardless of the client's instructions
The CPA should follow the client's instructions completely because the client owns all documents
Explanation
This scenario involves a tension between the client's instructions and the practitioner's Circular 230 obligations. A practitioner may not assist in obstructing the IRS's legitimate access to information (Section 10.51). At the same time, the client has a legal right to assert applicable privileges (attorney-client, taxpayer advocate) and the CPA must advise the client of available legal protections. The CPA should advise on consequences of non-production, help the client assert valid privileges, but not assist in improper obstruction. Option B ignores client rights. Option C requires premature withdrawal. Option D ignores the practitioner's independent obligations.
