Last year I received 16k from the government and no one knows.
Were you planning on sharing this information to people on this site?
No, i really want to keep this information to myself actually.
Receiving money from the government unintentionally might be a crime. If you don't correct this error you may end up in jail if you get caught.
There is no way I can go to jail for this minor crime.
If the government sent the money to you accidentally then you may just want to act like you never knew. I am not sure whether it is against the law or not to keep this money. Either way, doing the honest thing in this situation is probably the safest option.
