Professional Courtesy: If you like being on hold for 30 to 60 minutes with the IRS and having to wait 14 days to get a letter mailed to you with your EIN number before you can setup a bank account than don’t print off your EIN after registering with the Feds.
My pro tip today for all the startup businesses out there is to print off your EIN! Print it! You will not receive an email confirmation with your EIN information. Don’t get stuck in a call queue that makes a line at Disneyland look like a dream come true.
