I know that some businesses accept cash in exchange for services and never declare that income (tax evasion). I understand that it is illegal for businesses to do so. But what about the other end of the stick?
What happens if a person proposes a cash-for-services deal to a business to avoid having to pay taxes on the service? What if the person actually proceeds with the transaction?
Does the client have any legal liability? Or is the liability only present on the business end?
