WASHINGTON — More than 3.2 million Social Security recipients who received pensions from their time as teachers, firefighters, police officers and other public service jobs will soon see a boost in their benefits. Most people will receive their one-time retroactive payment by the end of March, and new monthly payments will begin in April, the agency said.

The Social Security Administration said it would begin processing retroactive payments and will send increased monthly payments to people affected by the Windfall Elimination Provision and Government Pension Offset, which were rescinded in the bipartisan Social Security Fairness Act that then-President Joe Biden signed into law last year.

The Windfall Elimination Provision and the Government Pension Offset limited Social Security benefits for recipients if they got retirement payments from other sources, including public retirement programs from a state or local government.

Advocates say the Social Security Fairness Act rights a decades-old disparity, though it also puts a strain on Social Security Trust Funds.

The annual Social Security and Medicare trustees report released last May said the program’s trust fund will be unable to pay full benefits beginning in 2035.

The new law will hasten the program’s insolvency date by about six months, the agency said.

“Social Security’s aggressive schedule to start issuing retroactive payments in February and increase monthly benefit payments beginning in April supports President Trump’s priority to implement the Social Security Fairness Act as quickly as possible,” said Lee Dudek, acting commissioner of Social Security in a statement. “The American people deserve to get their due benefits as quickly as possible.”

The Congressional Research Service estimated in 2023 there were 745,679 people, about 1% of all Social Security beneficiaries, affected by the GPO. About 2.1 million people, or about 3% of beneficiaries, were affected by the WEP.
