TpState means taxpayer state. Since you live in IL and need numbers, it must be your IL PIN. If you live in IL, you MUST get an IL PIN from the state department.
If you don’t know your Illinois PIN you can:
- look it up on Illinois’ website, Get Your IL-PIN
- or by calling (800) 732-8866 or (217) 782-3336.
