The IRS contacted your client as part of an examination of its tax return and proposed that the client owes an extra $100,000. As the client’s tax accountant and a CPA, can you agree to handle the matter for 40 percent of what you save the client? Under what circumstances might this be an acceptable form of payment for services rendered and when might it be unacceptable and in violation of the AICPA rules and/or SSTS? Notwithstanding the AICPA rules and SSTSs, is there anything ethically improper with agreeing to handle the matter for 40 percent of what you save the client?
