Social Security Fairness Act This bill repeals provisions that reduce Social Security benefits for individuals who receive other benefits, such as a pension from a state or local government. The bill eliminates the government pension offset , which in various instances reduces Social Security benefits for spouses, widows, and widowers who also receive government pensions of their own. The bill also eliminates the windfall elimination provision , which in some instances reduces Social Security benefits for individuals who also receive a pension or disability benefit from an employer that did not withhold Social Security taxes. These changes are effective for benefits payable after December 2023.
