My client wanted her Social Security benefits deposited to her Walmart debit card. After her disability claim was approved by Social Security, the U.S. Treasury tried to direct deposit her back benefits to the Walmart debit card. Unfortunately, Walmart limits each individual direct deposit to one of its debit cards to $7,000. My client's back benefits were more than $7,000 so the money bounced back to the U.S. Treasury delaying her receipt of the back benefits. Watch out on Walmart debit cards. They can cause problems for many people applying for Social Security disability benefits.
