For filers using fillable PDFs, you must lock or flatten the PDF document after completing the form fields. This ensures the document can be viewed on all devices, and prevents others from manipulating or editing the information.

Quick Steps to Flatten PDF Forms

  1. Open your fillable form.
  2. Add the appropriate data.
  3. In the top menu, select File.
  4. Select Print.
  5. Select the PDF printer. (The Adobe PDF printer is installed automatically with Adobe Acrobat. Numerous free PDF printer drivers are available for download from the Internet.)
  6. Select OK.
  7. Specify a location on your computer to save the printed (flattened) version of the form.
  8. Select Save.
