Social Security’s retirement trust fund is projected to be depleted by late 2032, according to the annual report released Tuesday by the program’s Board of Trustees. The projection moves the expected exhaustion date three months earlier than last year’s estimate and one year earlier than the previous forecast of 2033.

The report warns that unless Congress addresses the shortfall before reserves run out, beneficiaries will see an automatic reduction in monthly payments. “The Trustees recommend that lawmakers address the projected trust fund shortfalls in a timely way to phase in necessary changes gradually and give workers and beneficiaries time to adjust,” the report states.

The potential cuts would be substantial. The Committee for a Responsible Federal Budget estimated that the average monthly benefit reduction would total roughly $500 per household, which exceeds what the average retired household spends on groceries each month.

The trustees identified several factors driving the accelerated timeline. The tax cut passed by the Republican-controlled Congress last year reduced revenue by giving senior citizens an additional deduction that lowered taxes on Social Security benefits for many recipients. Declining birth rates and reduced immigration are also shrinking the number of workers paying into the system, according to the report. Those pressures are partially offset by stronger productivity gains, the trustees said.

The demographic challenge underlying Social Security’s finances is long-standing. Baby boomers are retiring in large numbers, and there are fewer younger workers contributing payroll taxes for each retiree drawing benefits. The trustees on Tuesday reduced their long-term expectations for fertility rates, indicating they will remain lower for longer than previously projected.

Congress could address the shortfall by raising taxes, reducing benefits, borrowing more, or a combination of those measures. The program averted insolvency with bipartisan legislation in 1983 that included both tax increases and benefit cuts. But serious negotiations have not materialized.

“There have not yet been serious public conversations about what they might do,” said Kathleen Romig, a senior fellow at the Center on Budget and Policy Priorities.

Marc Goldwein, senior vice president at the Committee for a Responsible Federal Budget, echoed that assessment. “For the most part this is something people don’t want to talk about,” he said. “Now that it’s quite urgent, there is no momentum.”

Sen. Bill Cassidy (R., La.), a longtime advocate of Social Security reform, is leaving Congress, removing a key figure who had pressed for legislative action.

On a combined basis, the retirement trust fund and the disability insurance trust fund are projected to become insolvent in the third quarter of 2034, three months earlier than previously forecast. Congress could temporarily shift money from the disability fund to prop up the retirement fund, but that would only delay the combined insolvency date.

A separate report from Medicare’s trustees found that the program’s hospital insurance trust fund will be able to pay 100% of benefits until 2033 — one quarter earlier than last year’s projection. After depletion, incoming revenue would cover 89% of scheduled benefits.

President Trump has vowed not to reduce retirement benefits. Some Americans, concerned about the program’s future, have begun claiming Social Security earlier than planned, even though that can reduce their lifetime income. Economists and financial advisers generally advise against early claiming unless life expectancy is short, because benefits increase for each month a person waits beyond age 62, up to age 70.

Social Security currently pays monthly benefits to an average of nearly 69 million Americans, including retirees, disabled individuals, and children, totaling about $1.6 trillion in annual benefits, according to the Social Security Administration.
