Social Security's May payment schedule is normal for most recipients. But Supplemental Security Income beneficiaries will get two checks this month.

The first 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 13 days. Social Security payments typically begin on the second Wednesday of every month,

The Social Security Administration said that nearly all of the 74 million Americans who receive benefits will be paid electronically on a Wednesday.
