Al Capone was famously taken down for tax evasion for not reporting income from his illegal activities. If someone were to report the income from illegal activities like a marijuana dispensary or a bribe, my understanding is that they would be prosecutedthen investigated/prosecuted for their disclosed activities. However, The Fifth Amendment states that:
No person ... shall be compelled in any criminal case to be a witness against himself,...
Since reporting income, even if illegal, is a mandate and the Fifth Amendment protects against someone being held as a witness against themselves, the law seems to be inconsistent. How does the mandate to report income from illegal activities in the US jibe with the Fifth Amendment right against self incrimination?
