Millions still haven’t received their May Social Security checks. Find out who gets paid on May 21 and May 28, plus what to do if your payment is delayed.

The second round of May’s Social Security payments, worth up to $5,108 for the highest-income earners who retire at age 70, will go out to retirees in five days.

Depending on your birthdate, traditional Social Security recipients will begin getting paid on May 14 this month, a bit later than usual.
