The department has changed all fill-in forms to PDF fill-in. You will be able to save and reuse these PDF forms. However, you will need Adobe Acrobat Reader 7 or higher to save the PDF fill-in form. Also, at this time the department does not accept digital signatures. If your Acrobat Reader prompts you to use one, we ask that you don't.
