Is it wise to come clean if you’ve committed unemployment fraud

Your question probably did not get too many answers. Wise is subjective.  This is less a question of law and more a question of ethics.  If you are asking if you will get away with your crime, then the answer is : I don't have a crystal ball.   If you are asking about the morality or ethical ramifications,  I imagine it would depend on how well you sleep at night or if you care about the oppions of others.  Its not ethical. If you are asking about consequences, I would tell you that if you make recompense and advise them of the "mistake", you can probably have no further consequences other than paying back the difference. Good luck.
