A cpa firm performs the annual audit of the leahy group, a private company. The client has asked the firm to perform a study to determine whether the company would qualify for certain municipal tax credits and prepare the application. The firm will receive 15% of any tax credits that leahy obtains for the client as a result of the requested credits but no fees if the request is denied. Leahy does not expect city officials to perform a substantive review of its client's application. Would this fee arrangement be permitted under the aicpa code of professional conduct?.
