Final answer:
Disclosing client's confidential information can severely damage an accountant's credibility, lead to legal consequences such as lawsuits, and potentially result in the loss of their professional license.
Step-by-step explanation:
Disclosing a client's confidential information would likely have significant and detrimental impacts on an accountant's professional standing and trustworthiness. If an accountant breaches confidentiality, they could face a loss of credibility with other clients, who may no longer trust them to maintain the confidentiality of their information. Moreover, the accountant may suffer legal consequences, such as lawsuits or loss of license, depending on the nature and severity of the breach. Accountants have a legal and ethical obligation to maintain confidentiality under professional standards such as the American Institute of Certified Public Accountants (AICPA) Code of Professional Conduct.
