Fixing the Formula: How the Social Security Fairness Act Is Quietly Restoring Trust in Retirement
Sen. Susan Collins spent more than two decades leading a bipartisan effort to repeal two obscure Social Security rules that cut benefits for many public servants, culminating in the Social Security Fairness Act signed into law in January 2025. The change has already boosted benefits for 2.8 million Americans — including more than 25,000 Mainers who have received nearly $185 million in retroactive payments — restoring retirement security to workers who paid into the system over a lifetime of public service.
Sen. Susan Collins spent years hearing the same story from Maine teachers, firefighters and state workers: They had paid into Social Security in earlier jobs or side work, only to see their retirement checks cut — sometimes sharply — once they also collected a public pension.
On Jan. 5, 2025, the obscure rules behind those reductions were wiped off the books when President Joe Biden signed the bipartisan Social Security Fairness Act into law. Collins, a Republican who first pushed the issue in the early 2000s and later co-authored the bi-partisan bill, called it the payoff for a two-decade campaign to end what retirees described as a quiet penalty on public service.
“Since the Social Security Fairness Act became law, benefits have increased for 2.8 million Americans,” Collins said in a one-year anniversary statement, adding that more than 25,000 Mainers have reportedly seen their earned benefits restored and Maine residents received nearly $185 million in retroactive payments, according to her office.
The law repealed two provisions that had reshaped retirement math for generations of public employees: the Windfall Elimination Provision and the Government Pension Offset. Together, they reduced — and in some cases eliminated — Social Security benefits for people who earned a government pension from work not covered by Social Security payroll taxes, even if those workers also qualified for Social Security through other jobs or through a spouse.
At the White House signing ceremony, Biden cast the bill as a straightforward fairness issue. “Americans who have worked hard all their lives to earn an honest living should be able to retire with economic security and dignity,” he said, adding that the measure would extend Social Security benefits for millions of teachers, nurses and other public employees, as well as their spouses and survivors.
For Collins, the moment was personal — and political. She had chaired a 2003 Senate hearing on the issue and reintroduced repeal legislation repeatedly, arguing that the rules discouraged public service careers and punished people who moved between the private and public sectors. Her office’s timeline points to the 2005 bill she introduced with Sen. Dianne Feinstein, who later died, as an early version of the long-running push.
The changes were not small. Social Security’s own overview of the law says ending WEP and GPO affects more than 2.8 million people who receive pensions based on work not covered by Social Security, raising benefits for certain workers and families.
WEP primarily reduced a worker’s own Social Security benefit if they also received a “noncovered” pension. GPO hit spousal and survivor benefits — a provision advocates said fell especially hard on widows — by offsetting those payments against a government pension and sometimes wiping them out entirely.
Advocacy groups and unions spent decades trying to get rid of both provisions, which were enacted years apart — GPO in 1977 and WEP in 1983 — and were defended for years by lawmakers concerned about cost and Social Security’s finances.
Labor leaders framed the repeal as a rare, clear victory for a politically contentious program. “Finally, GPO-WEP is gone for good,” AFSCME President Lee Saunders said the day after the signing, calling the rules “outdated” and crediting years of petitions, letter-writing campaigns and trips to Washington.
In Maine, advocates say the impact shows up most clearly not in federal jargon, but in monthly bills. Penny Whitney-Asdourian, a retired state employee in Scarborough, has described how reductions tied to WEP forced difficult trade-offs for her household — including the cost of heating a home through winter and the annual burden of property taxes and homeowners insurance.
The law’s real-world consequences also extend beyond retirees’ household budgets. Economists often note that Social Security payments behave like steady local stimulus: recipients typically spend on essentials — groceries, utilities, housing — keeping dollars circulating in communities.
Sen. Bill Cassidy, a Republican co-sponsor from Louisiana, has pointed to the law's local economic effects, with his state seeing substantial retroactive payments returned, according to advocates.
That implementation timeline matters, because the law’s effect was retroactive. Social Security says benefit increases apply back to January 2024, meaning eligible recipients could receive a one-time back payment for amounts previously withheld.
On Feb. 25, 2025, the Social Security Administration announced it had begun issuing retroactive payments and said it would raise ongoing monthly payments beginning in April 2025, after initially warning the process could take a year or more.
For Collins, the law is now both a policy win and a political calling card: a bipartisan achievement she can tie directly to constituent stories — and to a persistent argument she has made for years, that public servants should not be penalized for building “blended” careers.
America’s workforce has become more mobile and more complicated than the system designers of the 1970s and 1980s assumed. Workers shift between private and public roles, take second jobs, re-enter the workforce after caregiving, or change careers midlife. Those patterns collided with rules that treated certain pensions as a reason to scale back Social Security benefits even when workers had paid into the system.
In that sense, the Social Security Fairness Act is about more than two acronyms. It is a reminder that the most consequential government policies are sometimes the most technical — and that political perseverance can turn a decades-old grievance into a tangible raise for retirees.
Collins, marking the law’s anniversary, put it in moral terms: retirement security and dignity for people who served their communities. For thousands of Maine families, she said, that security is now arriving not as a promise, but as a deposit.
