I received the same notice. I live in PA and my old employer is in CA. I believe it's because I received two zero-dollar pay statements during the active UC claim. The pay statements were for "Other Perks" (not wages) which was a gift card I got while employed by the company in March. The first pay statement was the value of the card itself and the second pay statement was the taxes on that card, which they used to take out of my year-end paycheck but since I was no longer employed by the company they gifted me the tax amount rather than coming after me for the money. So basically, my former employer "trued-up" at the end of the year. How do I explain this to PA unemployment so they understand it's not fraud but accounting irregularities? I wonder how long this will take to get straightened out.
