Also, if you already efiled the Federal return, you will not be able to efile the State return until the Federal return has been accepted, and the forms ready. The IRS will not start processing returns until January 23 (except
for a few test returns the IRS will pull early.). Any returns filed
early will just sit on TurboTax servers until then and cannot be
retrieved if you notice something wrong.
You must wait on any W-2's, 1099's, etc. to arrive first before filing.
And starting this year, if you have EIC (earned income credit) or ACTC (additional child tax credit), the IRS will not start releasing those refunds until February 15.Enter your E-mail address. We'll send you an e-mail with instructions to reset your password.
