Which of the following is most likely a violation of the Code of Ethics?

• A. The professional accountant bills a client a fee lower than previously charged for similar services.
• B. The professional accountant represents that specific professional services in the current or future periods will be performed for a stated fee if it is likely at the time of representation that such fee will be substantially increased.
• C. The professional accountant in public practice is the one who determines the billing rates of each professional staff engaged in performing services.
• D. The professional accountant agrees to the client's proposal for a professional fee that is dependent on the number of service hours rendered.

Answer: (D)

The main idea here is that fee arrangements must not introduce bias or mislead about the engagement. A fee that depends on the number of service hours rendered creates a direct financial incentive for the professional to expand the scope or length of the engagement to earn more. That undermines objectivity and independence, which are essential in performing professional services, especially audits or attestation work. Because of this potential to unduly influence professional judgment, this kind of arrangement is considered a violation of the Code of Ethics.

Other options aren’t inherently unethical. Charging a lower fee than before can happen for competitive reasons or negotiated discounts and isn’t itself a violation. Representing that a fee will be a stated amount if it’s likely it will rise later is problematic because it involves potential misrepresentation about future pricing. Having the firm set billing rates for its staff is a normal practice and doesn’t by itself threaten independence or objectivity.
