Gosh, Oh golly, you mean the IRS made a mistake. What is this world coming to?
The clients would be best advised to put the money in a separate bank account, because sometime within the next 3 years they may receive a letter from the IRS.
"Dear Taxpayer,
In August of2021 we sent you a refund check for $3000.00.
We are sorry to inform you that the person who calculated your refund was suffering from apoxia due to prolonged mask wearing.
Said person made an error in determining your refund, which we have found in its totality to be unwarranted.
Please accept our sincere apologize for this, but we demand that the $3000.00. plus interest of $27.33 be returned to us within 15 days, or interest will continue to accrue. Furthermore, failure to pay could subject you to collection action including levying your bank account and garnishing your wages.
