I'm getting an IC Pro error that says "Tax ID could not be verified -- SASSIE verification status is INVALID."
This message means that the process of verifying your tax ID from SASSIE failed because the IRS has rejected the combination of name and number as invalid. Please resolve the error in your SASSIE account by making sure both name and number are correct. Once the status of your tax ID shows in SASSIE as VERIFIED, you will be able to verify your tax ID in IC Pro.
