There is no single fix for the Social Security shortfall. The retirement trust fund is projected to run out of reserves by 2033, and once that happens, incoming payroll taxes would only cover about 77 percent of scheduled benefits, an automatic cut of roughly 23 percent for every retiree receiving a check.1Social Security Administration. Trustees Report Summary Any workable plan to fix the Social Security shortfall combines several of the approaches below, because each one on its own closes only part of the gap. The choices divide neatly into two camps: raise more money, or slow the growth of benefits.
Raising More Revenue
Increase the Payroll Tax Rate
The most direct way to bring in more money is to raise the payroll tax. Workers currently pay 6.2 percent of their wages, and employers match that for a combined 12.4 percent.2Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax3Office of the Law Revision Counsel. 26 USC 3111 – Rate of Tax A rate increase applies immediately and generates new revenue from the first paycheck, which makes it the fastest-acting option.
The math is easy to picture. A one-percentage-point increase, bringing the combined rate to 13.4 percent, would cost a worker earning $50,000 about $250 more per year, with the employer paying another $250. For most workers, that is a modest hit. For employers with thousands of staff, the aggregate cost is significant, and opponents argue it drags on hiring and wages. The tradeoff is that benefits stay exactly the same for retirees.
Lift or Eliminate the Taxable Wage Cap
Social Security taxes only apply to earnings up to an annual ceiling. In 2026, that ceiling is $184,500.4Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security Every dollar earned above that is completely exempt. Someone making $500,000 pays the same Social Security tax as someone making $184,500.
Removing the cap entirely would subject all wage income to the 6.2 percent tax on each side, generating substantial new revenue from the roughly 6 percent of workers who earn above the limit. A more moderate version, sometimes called the “donut hole” approach, keeps the current cap, skips earnings between the cap and $400,000, and resumes taxing wages above $400,000. Provisions in the Social Security 2100 Act use a version of this structure, letting the gap close over time as the taxable maximum rises.5United States Congress. H.R. 4583 – Social Security 2100 Act
There is a philosophical wrinkle. Under the current system, benefits are calculated based on taxed wages, so taxing more income would normally mean bigger checks in retirement. Most cap-removal proposals deliberately break that link for the newly taxed earnings, turning the extra revenue into a pure transfer rather than earned insurance. That is a real shift for a program originally designed so that what you get out is proportional to what you put in.
Expand the Workforce Through Immigration
The program’s underlying problem is demographic. Fewer workers are supporting more retirees, and the birth rate has not recovered enough to reverse that trend. Immigration adds working-age contributors directly. Estimates from policy analysts show that each increase of 100,000 in net annual immigration improves the program’s 75-year actuarial balance by about 0.1 percent of taxable payroll, and varying immigration assumptions account for nearly a quarter of the swing in long-term shortfall projections.
Immigration is not a permanent fix, because immigrants eventually retire and collect benefits themselves. But the timing helps: new workers pay in for decades before they draw, which buys the trust fund time. Over 75 years, the net effect depends on the age, earnings, and fertility rates of the immigrant population.
Slowing Benefit Growth
Raise the Full Retirement Age
The full retirement age already climbed from 65 to 67 under a schedule Congress set in 1983, with the last phase-in reaching people born in 1960 or later.6GovInfo. 42 USC 416 – Additional Definitions Some proposals would push that threshold to 69 or 70, on the argument that life expectancy has risen enough to justify a longer working career. Any shift would be phased in gradually and would primarily affect workers now in their twenties or thirties.
The sharpest practical consequence hits people who claim at 62, the earliest age allowed. Filing at 62 with a full retirement age of 67 already produces a 30 percent permanent reduction in monthly benefits.7Social Security Administration. Early or Late Retirement If the full retirement age moved to 70, a 62-year-old claimant would face roughly a 45 percent reduction, because the actuarial penalty accumulates over 96 months instead of 60.8Social Security Administration. Effect of Early or Delayed Retirement on Retirement Benefits
Longevity gains are not evenly distributed. Research published by the Social Security Administration found that men in the top earnings quartile gained about 4.0 years of life expectancy at age 65 between the 1928 and 1960 birth cohorts, while men in the bottom quartile gained only 1.6 years.9Social Security Administration. Changing Longevity, Social Security Retirement Benefits, and Potential Adjustments Higher earners live longer and collect for more years. Lower earners often work physically demanding jobs and have shorter retirements to collect from. Raising the retirement age across the board hits them hardest.
Switch to the Chained Consumer Price Index
Each year, benefits get a cost-of-living adjustment based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W.10Social Security Administration. Latest Cost-of-Living Adjustment A recurring proposal would swap that for the Chained Consumer Price Index, which accounts for the way consumers substitute cheaper goods when prices rise. If steak gets expensive, people buy more chicken, and the chained index reflects the shift.
The difference sounds trivial. The chained index historically grows about 0.2 percentage points slower per year than the standard CPI.11Bureau of Labor Statistics. Frequently Asked Questions About the Chained Consumer Price Index Compounding makes small differences painful over a long retirement. A retiree starting at $2,000 a month would see the benefit fall hundreds of dollars below what the current formula would produce by their mid-eighties. The trust fund savings are real, and Social Security actuaries have estimated the switch would delay insolvency by several years.12Social Security Administration. Social Security Cost-of-Living Adjustments and the Consumer Price Index
Critics point out that older Americans spend disproportionately on healthcare, where prices rise faster than the overall index and where substitution is harder. You can switch from beef to chicken. You cannot easily switch away from a prescribed medication that has no cheaper equivalent.
Reduce Benefits for Higher Earners
Social Security’s benefit formula replaces a larger share of income for lower earners and a smaller share for higher earners. The 2026 formula replaces 90 percent of the first $1,286 in average indexed monthly earnings, 32 percent of earnings between $1,286 and $7,749, and 15 percent of anything above $7,749.13Social Security Administration. Benefit Formula Bend Points These thresholds, called bend points, are where reform proposals typically intervene.
Lowering the 32 percent or 15 percent replacement rates would shrink benefits for middle- and high-income retirees while leaving the 90 percent rate for lower earners intact. Some proposals go further and introduce outright means testing, reducing or eliminating benefits for retirees with significant non-Social Security income from pensions, investments, or other sources. A few would also look at accumulated assets, though implementing an asset test adds administrative complexity.
This approach saves money, but it changes the character of the program. Workers who see no return on decades of payroll taxes have less reason to support it, and the machinery needed to verify incomes and assets every year adds cost. Still, targeting reductions at retirees who need the income least is among the more intuitive ways to stretch the trust fund.
Structural Options
Invest Trust Fund Reserves in Equities
By law, Social Security’s trust fund reserves are invested entirely in special-issue U.S. Treasury bonds. These are safe, but their returns are modest. The idea of investing some portion in a broad stock index fund has surfaced repeatedly since the 1990s.
The Congressional Budget Office analyzed the approach and found that an ambitious shift toward equities could extend the trust fund’s life by roughly eight years if stocks performed as expected. Once the additional risk is factored in, the expected advantage largely disappears. A defined-benefit version, where the government guarantees specific benefit levels regardless of market performance, shifts the risk onto future taxpayers who would have to cover any shortfall. A defined-contribution version, where retirees absorb market risk directly, means a bad stretch in markets could devastate benefits for an entire generation.
There is also a governance concern. Federal ownership of significant stakes in private companies raises questions about who votes the shares and whether Congress could pressure fund managers on politically disfavored industries. Those questions have never been resolved, and they are a major reason the idea keeps stalling.
Strengthening Benefits at the Bottom
Not every proposal is about closing the gap through cuts. Some reforms would increase benefits for people who worked for decades at low wages and still receive very small checks. The program’s special minimum benefit was designed for long-career low earners, but it has eroded because it is indexed to prices rather than wages. Several proposals would overhaul it, with some setting it at 125 percent of the federal poverty guideline, projected to reach roughly $1,645 to $2,000 per month in 2026 depending on the indexing method.14Social Security Administration. Proposed Revisions to the Special Minimum Benefit for Low Lifetime Earners
A related idea would grant Social Security credits to workers who leave the workforce to care for young children. One version modeled by the Social Security Administration would credit up to five years of earnings at half the national average wage for caregivers of children under six.15Social Security Administration. Projected Effects of a Proposal to Credit Earnings to Caregivers Records These provisions cost money rather than save it, so they typically get paired with revenue-raising measures like a wage cap increase or payroll tax hike.
How Reform Bills Package the Pieces Together
Most single proposals close only a fraction of the shortfall, which is why legislative packages stack several at once. The Social Security 2100 Act, for example, would raise the benefit formula’s first bracket from 90 percent to 93 percent, apply payroll taxes to income above $400,000, and merge the retirement and disability trust funds into a single pool.5United States Congress. H.R. 4583 – Social Security 2100 Act It would also repeal the windfall elimination provision and the government pension offset, two rules that currently reduce benefits for public-sector workers with pensions from jobs not covered by Social Security.
Every combination produces winners and losers. Packages heavy on tax increases face resistance from employers and higher earners. Packages heavy on benefit reductions face resistance from retiree advocacy groups. And the longer Congress waits, the more painful any fix becomes. Social Security actuaries have noted that reserves have been projected to run out between 2033 and 2035 under intermediate assumptions in every Trustees Report since 2012, with roughly three-fourths of benefits payable from ongoing tax revenue after depletion.16Social Security Administration. Proposals to Change Social Security Every year of inaction narrows the menu of workable options and steepens the eventual adjustment.
