You may be charged with an overpayment of unemployment benefits, which you will have to repay before any further or future benefits can be paid to you. You may also be disqualified from receiving unemployment benefits.
If you are working and drawing benefits, it will be discovered through a periodic audit of your unemployment claim for benefits.
Your claim for unemployment benefits may be audited, even after your claim ends. Your claim is audited by comparing any weeks where you were paid benefits with any wages reported by your employer during the same time period.
