Final answer:
A CPA partnership may provide working papers to the IRS, SEC, and PCAOB without the client's consent or a lawful subpoena due to their regulatory authority. The AICPA does not have the authority to demand such documents without consent or legal directive.
Step-by-step explanation:
To which of the following parties may a CPA partnership provide its working papers without either the client's consent or a lawful subpoena? The correct parties to which a CPA partnership can disclose working papers without client consent or subpoena are regulatory bodies with legal authority over the accounting profession or with the jurisdiction to demand such records as part of their oversight functions.
In the United States, this can include:
The Internal Revenue Service (IRS) for tax-related investigations or audits.
The Securities and Exchange Commission (SEC) for matters related to securities laws and regulations, particularly for firms that audit public companies.
The Public Company Accounting Oversight Board (PCAOB), which is established by the Sarbanes-Oxley Act to oversee the audits of public companies in order to protect the interests of investors and further the public interest in the preparation of informative, accurate, and independent audit reports.
However, the American Institute of Certified Public Accountants (AICPA) is not a regulatory body with legal authority to demand working papers without client consent or a lawful subpoena.
