How long does it typically take to get your tax return back?

For most people the IRS will not start processing returns  until January 27, so most people who efile now won't know anything about the efile status until after January 27, except for a few returns that are pulled early for testing purposes.    Once the IRS opens, it generally takes 24-48 hours to hear if accepted or rejected, but there can be a backlog at first.

To check the efile status you can log back into your Online TurboTax account periodically and check the status at the Tax Home page.  You should also get an email notice when the return is accepted or rejected.  But as I said above, for most people that will be after January 27.

The IRS says 9 out of 10 filers who efile and choose direct deposit will get their refunds within 21 days after acceptance. That still leaves a considerable number of people who do not. Some returns take longer for additional processing due to specific items in the return. Some are pulled at random for more thorough investigation.

Once your efile return has been accepted by the IRS, you can monitor the refund status with this IRS tool:

NOTE: When using that tool, use only the Federal refund amount, and not any total refund amount that includes a state refund.
