What Browser Works Best for the Greenback Portal?

The Greenback portal works best in the latest version of any major browser, including Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge. Keeping your browser updated gives you the smoothest experience when uploading documents and reviewing your draft return.

Tips for a trouble-free session:

• Use the latest version: An up-to-date browser handles secure uploads and the questionnaire reliably
• Enable cookies and JavaScript: Both are needed for login and the guided questionnaire to work
• Clear the cache if something looks off: Refreshing or clearing the cache resolves most display glitches
• Switch browsers as a quick test: If a page will not load, trying a different supported browser often helps

If the portal is not behaving as expected on your device, send the details through our contact form and the team can troubleshoot with you.
