A Submission ID is a unique 20 digit confirmation number given by the IRS or State when you submit a tax return electronically.
Where can I find my Submission ID Number?
You can find your Submission ID Number within your account.
To access your Submission ID number, login to your account, scroll down and click the link, “View Details” (located below your federal and/or state return information).
What is the Submission ID Number used for?
Each time you submit your return for processing, a new Submission ID number is issued as confirmation, so if you are contacting the IRS/state about your return, use the number associated with that transmission.
