Use the new Social Security Number. Once a Social Security Number has been issued, the Social Security Administration notifies the IRS and that is the number they want you to use.
Same scenario here, i used to enter ITIN, now am entering SSN and Federal rejected my online filing, saying it didnot match last year. What should i do ?
If the change was done very recently, the process of the Social Security Administration notifying the IRS may not have been completed. You can wait a week and try again, or paper-file and mail the return in to the IRS.
