By now, millions of Americans have received their third stimulus check, but some of the recipients of the $1,400 direct payment need to return theirs to the government.

According to Kiplinger, there are a few reasons a person might need to send the check back to the IRS. The first is if the recipient is classified as a nonresident alien. This means they are not a US citizen, do not have a green card, and aren't in America for a required amount of time. While qualifying resident aliens who have a green card and a Social Security number were eligible and can keep their check, the nonresident aliens might have gotten one by mistake and need to return it.

Others who have to send their check back are some widows and widowers. If a married couple received the payment but one of the spouses has passed away, it needs to be returned along with a letter explaining the situation. At that point, the IRS will re-issue a payment just for the living spouse.

There is also a third group of people who are supposed to send their checks back, but are not required to. It's anyone who doesn't need or want the money. The IRS is encouraging them to return their payments.

If you fall into any of the three groups, and received a debit card, you can mail it back to: Money Network Cardholder Services, 2900 Westside Parkway, Alpharetta, GA 30004. Be sure to include a note as to why you don't want it. As for the paper check, you'll have to void it by writing "void" in the endorsement field, then send it back to the appropriate IRS address below with a note that includes the reason you are returning it. If you've already deposited the check or it was a direct-deposit, make a personal check out to US Treasury and write Third EIP and your taxpayer ID number in the memo field. Once again, include an explanation of why you are returning it and send it to the appropriate address below.

There is no word on what might happen if you don't send a check back that should be returned, but knowing the IRS, they will likely find out about it and eventually it will catch up to you.
