Social Security’s long-range finances weakened more in a single year than they have in over a decade. The Social Security Board of Trustees, in its 2026 Trustees Report released June 9, 2026, projects the program’s 75-year actuarial deficit at 4.42 percent of taxable payroll, up from 3.82 percent projected in last year’s report. For an older reader watching a monthly Social Security check, the increase changes nothing about what arrives in a bank account today, but it does compress the time lawmakers have before trust fund reserves run out. The Trustees frame the number as a projection built on assumptions about births, immigration and the economy, not a settled forecast of what will happen over the next 75 years.
The 75-Year Deficit Widens From 3.82 to 4.42 Percent of Payroll
The Trustees measure the program’s long-term health with a single summary number called the actuarial balance, expressed as a share of the taxable payroll the system is projected to collect between 2026 and 2100. A negative balance is called an actuarial deficit, and this year’s report puts that deficit at 4.42 percent of taxable payroll, compared with 3.82 percent in the 2025 report. Roughly half of that movement is mechanical: simply rolling the 75-year window forward by one year, from 2025-2099 to 2026-2100, would have pushed the deficit to 3.89 percent on its own.
The remaining increase, about 0.53 points, reflects genuine changes in demographic assumptions and law. In present-value dollars, the Trustees now put the 75-year unfunded obligation at $29.3 trillion, up from $25.1 trillion in the 2025 report, or 1.5 percent of projected gross domestic product through 2100.

A Lower Fertility Assumption Drives Most of the New Shortfall
The single largest driver behind the widened deficit was a revision to the Trustees’ long-term fertility assumption. This year’s report assumes an ultimate total fertility rate of 1.75 children per woman, down from 1.90 in last year’s report, reflecting the continued decline in U.S. birth rates. Fewer future births mean fewer future workers paying payroll taxes relative to the number of retirees drawing benefits, which worsens the program’s cash-flow math for decades.
Two other factors added to the gap. The Trustees lowered their assumed levels of immigration, both for the temporary or unlawfully present population entering the country and for the ultimate level of future entrants, while raising assumed emigration rates for that population. Separately, the One Big Beautiful Bill Act, enacted July 4, 2025, permanently raised the standard deduction and added a temporary extra deduction for taxpayers over 65, which reduces the income tax revenue that flows into the trust funds from taxation of Social Security benefits.
OASI Reserves Now Projected to Deplete in the Fourth Quarter of 2032
The retirement portion of the program, the Old-Age and Survivors Insurance Trust Fund, is now projected to exhaust its reserves in the fourth quarter of 2032, one quarter earlier than the 2025 report projected. The separate Disability Insurance Trust Fund is projected to stay positive through the full 75-year window. Combined, the OASI and DI trust funds are projected to deplete their reserves in the third quarter of 2034, the same timing projected a year ago.
A widening annual cash gap sits behind those dates. The combined trust funds took in $1.45 trillion in 2025, mostly from $1.32 trillion in net payroll taxes, while paying out $1.61 trillion, mostly in benefits. That roughly $160 billion shortfall was covered by drawing down reserves, which fell from $2.72 trillion at the start of 2025 to $2.56 trillion by year’s end.
Why 78 and 83 Percent Payable Is Not the Same as Benefits Stopping
Trust fund depletion does not mean Social Security stops paying benefits. Because the program continues to collect payroll taxes even after its reserves are gone, incoming revenue alone is projected to cover 78 percent of scheduled OASI benefits once reserves deplete in the fourth quarter of 2032, a share that would gradually decline to 62 percent by 2100 absent congressional action. For the combined OASI and DI funds, depletion in 2034 would still leave enough incoming revenue to pay 83 percent of scheduled benefits, declining gradually to 65 percent by 2100.
That distinction matters for anyone planning retirement income around these projections. A reduction to 78 or 83 percent of a scheduled benefit is a meaningfully smaller check, not a vanished one, and current law does not allow partial payments to be skipped selectively. It would only take effect if Congress allows the trust funds to run out without acting, something that has not happened in the program’s 89-year history.
What It Would Take to Close the Gap Today Versus in 2034
The Trustees translate the shortfall into concrete policy terms to illustrate its size. Bringing the combined program into 75-year balance starting immediately in 2026 would require raising the payroll tax rate from 12.40 percent to 16.65 percent, or cutting scheduled benefits by 25.2 percent for all current and future beneficiaries, or reducing benefits by 30.3 percent only for people newly eligible in 2026 or later, or some blend of the two. Waiting until reserves are exhausted in 2034 would concentrate the fix into fewer years: a payroll tax increase to 17.30 percent, or a 28.5 percent benefit cut applied to everyone at once, current beneficiaries included.
Bisignano and the Trustees Call on Congress to Act
Social Security Commissioner Frank Bisignano, one of the four members of the Board of Trustees alongside Treasury Secretary Scott Bessent, Health and Human Services Secretary Robert F. Kennedy Jr. and acting Labor Secretary Keith Sonderling, said in the June 9 announcement that “it is important for lawmakers and the Social Security Administration to work together to ensure the trust funds continue to provide financial stability now and for future generations.” The report closes with a similar recommendation, urging lawmakers to address the shortfall gradually rather than waiting for reserve depletion to force larger, more concentrated changes on fewer generations at once. Until Congress acts, 4.42 percent remains what the 2026 Trustees Report projects for the next 75 years, not a final determination of what any individual retiree will ultimately collect.
