Your question is Handling Unreported Cash Income. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you handle a situation where you are assisting a landscaper who provides a W-2 and says he also earns cash from clients but has not reported that income for the past three years? Explain how you would protect the client, maintain accurate records, and stay within tax-compliance and professional-conduct requirements. Address the information you would gather, what you would not do, and when you would escalate to a qualified tax professional.
