  • 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.
  • Recent versions of Chrome and Firefox’s PDF preview tools don’t work well with our forms. We recommend you disable the browser’s PDF preview tool and enable Adobe Reader (see below).
  • IE 10 and 11 are not compatible with Adobe Reader. If a blank page opens when you select a PDF link in IE 10 or 11, review Adobe’s instructions.
