Millions of retirees will see an increase in Social Security benefits after President Joe Biden signed a bill. Here's how benefits will change.

President Biden signed legislation into law over the weekend to expand Social Security benefits for droves of Americans. The measure, dubbed the Social Security Fairness Act, repeals two tax rules that proponents say have unfairly reduced benefits for many Americans who also receive government pensions.

The law will increase benefits for millions of retirees, but it's still not clear where the added funds will come from.

The new law repeals the Windfall Elimination Provision and Government Pension Offset, which affect some public workers.

With President Joe Biden signing a bill over the weekend to improve Social Security benefits for millions of public sector workers, many Americans may be wondering if they qualify for what the White House is calling the first expansion of such assistance in 20 years.

We’re extending Social Security benefits for millions of teachers, nurses, and other public and… employees and their spouses and survivors,” said Biden when he signed the Social Security Fairness Act this week.
