Common mistakes

  • Do not complete Form IL-1310 if you are a surviving spouse filing a joint return with your deceased spouse.
  • Check only one box in Step 1, Line 5. Complete Schedule A only for Box a or Box c.
  • Do not use a copy of the will as proof that you are the court-appointed personal representative. Attach a court certificate showing your appointment.
  • If you answer “yes” to Schedule A, question 2a or 2b, do not file this form. The personal representative should file for the refund.
  • If you answer “no” to Schedule A, question 3, do not file until you can submit proof of appointment as personal representative or other evidence that state law authorizes you to receive payment.
  • Do not leave out required information. The form warns that failure to provide information could result in a penalty.
