The IRS warns that roughly $1 billion in tax refunds from fiscal year 2021 could end up in the U.S. Treasury if more than 1.1 million Americans don’t act soon.
These refunds are for those who did not file their Federal Tax Return (Form 1040) for 2021, the taxes that were due in April 2022.
According to the IRS, the average refund is $781, not counting applicable tax credits.
