I filed my taxes and couldn't remember if we received the third stimulus. I didn't think we did and checked no. When I checked my bank account, we did receive the third stimulus. Do I need to amend the return once the IRS accepts it? Could we be accused of tax fraud? It was an honest mistake.
The IRS knows that the stimulus payment was sent to you so they will adjust your tax return accordingly. They see these types of mistakes all the time so do not worry about being accused of fraud. If you are still owed a tax refund the refund will be delayed for several weeks or longer.
There is no need to amend the 2021 tax return.
No, you don't need to file an amended return. The IRS will verify the information you entered about the stimulus checks against the information they have on their end and will adjust the refund amount accordingly.
However, due to this, if you were getting a refund, that will be delayed and there is no timeline on how long the IRS will take to reconcile this information and issue the adjusted refund.
