| I would hazard a guess that as long as your contract has been terminated, and you have no other sources of earned income, then depending on your State's requirements I would think that you may be able to claim unemployment in IL.
Additionally, you should terminate your S Corporation and take a distribution of all retained earnings out as there is no activity in the S Corporation.
I would still consult your Local unemployment Office just to be 100% certain that you are in the legal bounds. |
