How do I change my bank account number?

If you have not yet filed,  then you can change your bank information under the File section. However, if you have already filed or your return is in a pending state, it is too late to change it. 

You will need to wait until the return is accepted/rejected. If rejected, then you can go back into the file section and make the change. See below.

If you have already e-filed or mailed in your return, you are not able to make any changes to your refund options. If your financial institution rejects the deposit, the government will mail your refund check. 
Please see the FAQ: What if I entered the wrong bank account for direct deposit? for more information.

If you have yet to file your taxes, you can still change your direct deposit information by following the steps in this FAQ: How do I change my transferred direct deposit information?
