You can avoid this by paying the total amount due before requesting the appeal."
But it also says this, making it sound like if you paid or going to shouldn't use the form to appeal:
"Instructions: Use this form only if you want to request an appeal of your hearing decision. If you accept the judge’s decision and are going to pay or have paid the amount imposed, you should not submit this form. "
