Note: The IRS "Where's My Refund" online tool does not keep track of amendment refunds.

If you are amending a return in order to get an additional tax refund, you can go ahead and cash or deposit any refund you get in the meantime. However, do not file your amended return until after you receive the refund. It generally takes the IRS 16 weeks (or 4 months) to process an amended return, so you should wait at least 10 weeks before checking on the status of your new amended tax refund. Once your amended return has been processed, you will receive any additional refund you are owed.
