I checked online to track my Minnesota tax refund. There was no file for 2015.

Why cant I find my Tax refund filed??

Minnesota’s state tax forms were just released today (1/22/16).  For this reason, it is likely that your state tax return has not had sufficient time to be processed yet.

If you’ve successfully completed the e-filing process (without reject codes) and your federal tax return has been accepted, then It is recommended that you wait 24-48 hours and check the status of your state tax return again.  Links to track your federal and state tax returns have been provided below.

Note:  Your TurboTax state e-filed tax return cannot be processed until your federal tax return has been accepted by the IRS.

New Update: If you have questions regarding the status of your return, it is always helpful to verify that your return has been e-filed. Please see the information provided below to learn how to do this.
