Q: I believe that my adult son received a $1,200 EIP, via automatic deposit to his checking account, that he was not entitled to because he is my tax-return dependent. Will the IRS go into his checking account and debit it to get the money back?

A: No. The statutory language in the CARES Act that set the whole EIP scheme in motion says that anybody who gets more money than they are actually entitled to can keep the excess. I endorse that concept: any money that gets into people’s hands is fair game.
