  • Viewing your CalFile return may not work correctly
  • If you're working in CalFile and don’t see the Tax Return after selecting the image link, make sure the return is not open in another tab. If it’s in another tab and you’d prefer it pop up, you’ll need to change your browser settings to not open pages in new tabs.
