Some people don’t receive all their Social Security benefits, even though they paid into the system. A bill would change that.

The Senate will soon vote on legislation that would change Social Security benefits, impacting nearly 3 million people. Lawmakers have until the end of this year’s lame-duck session to pass the Social Security Fairness Act.

Lawmakers are moving ahead with a bipartisan bill that would provide enhanced Social Security benefits to millions of Americans, but hurdles remain.

Senate Majority Leader Chuck Schumer (D-N.Y.) said Wednesday he’s “doing everything” he can to try to pass legislation that would enact some Social Security reforms before Congress ushers in a new class next month.
