Social Security faces a long-term financing challenge, and the latest projections have put renewed attention on how the program could be funded in the years ahead. The retirement trust fund is projected to be depleted in the last three months of 2032 if current law remains unchanged. After that point, payroll taxes would continue to flow into the program, but incoming revenue would not be enough to pay scheduled benefits in full.
The Social Security trustees estimate that an immediate benefit reduction of about 22% could be required if policymakers do not address the shortfall. That does not mean a 22% cut is already scheduled. Rather, it illustrates the size of the adjustment that could be needed if no legislative changes are made.
Several options have been discussed, ranging from higher payroll taxes to changes affecting higher earners, retirement ages and annual benefit adjustments.
Tax
The current Social Security payroll tax rate is 12.4%. Employees generally pay 6.2%, while employers pay the other 6.2%. For self-employed workers, the combined amount is generally paid by the worker.
In 2026, Social Security payroll taxes apply to earnings up to $184,500. Earnings above that threshold are currently not subject to the Social Security portion of the payroll tax.
One potential solution would be to increase the payroll tax rate. The Social Security trustees estimate that a combined rate of 16.65% could close the program’s projected long-term funding gap if a tax increase were used as the primary measure.
The Congressional Budget Office has previously estimated that a combined payroll tax rate of 17.31% could address the long-term shortfall under its assumptions.
Costs
A higher payroll tax would increase the amount deducted from workers’ paychecks, although the exact effect would depend on the rate lawmakers ultimately choose.
The Cato Institute has estimated that a median full-time worker earning about $61,583 could face approximately $2,617 to $3,024 in additional annual taxes under different payroll-tax scenarios.
That would amount to roughly $218 to $252 per month.
The impact would not necessarily stop with the employee’s direct tax bill. Employers would also pay a larger share if the tax rate increased. Some economists argue that higher employer payroll taxes can eventually affect wages because businesses may adjust compensation and hiring decisions in response to higher labor costs.
Tax Cap
Another proposal would change the maximum amount of earnings subject to Social Security payroll taxes.
The 2026 taxable earnings maximum is $184,500. Under current rules, income above that amount is not subject to the Social Security payroll tax.
Raising the cap would increase the amount paid by workers with earnings above the current threshold. Removing the cap entirely would have a larger effect on high-income earners because a greater share of their wages would become taxable.
The details of such a proposal would matter. Depending on how the change is structured, higher earners could also receive additional Social Security credits in return for the additional taxes they pay.
This approach would therefore distribute more of the financing burden toward workers with higher earnings rather than applying the same additional tax rate to all covered wages.
Retirement
Increasing the full retirement age is another option that has been examined.
The current full retirement age is 67 for people born in 1960 or later. Raising the age would mean future retirees would need to wait longer to receive their full scheduled retirement benefit.
A higher retirement age would generally reduce benefits for people who claim at the same age they otherwise would have. Workers could still choose to claim earlier, but doing so would generally result in a larger reduction relative to their full retirement benefit.
A 2024 analysis from the Center for American Progress examined a proposal to raise the full retirement age to 69. It estimated that benefits for new retirees could eventually be reduced by as much as 14.3% after the change was fully phased in.
The effects would depend heavily on how quickly any increase was introduced and which generations were covered.
COLA
Another area lawmakers could consider is the annual cost-of-living adjustment, commonly known as COLA.
Social Security benefits receive annual adjustments intended to account for inflation. Changing the formula used to calculate those adjustments could slow the growth of benefits over time.
Unlike an immediate reduction in monthly payments, a change to the COLA formula could have a gradual effect. Even a relatively small difference in annual adjustments can accumulate over many years of retirement.
This makes COLA changes particularly important for people who receive Social Security for long periods. The ultimate effect would depend on the formula selected and future inflation.
Funding
The options for addressing Social Security’s financing gap involve different trade-offs.
A payroll tax increase would bring more revenue into the program but would also increase taxes on workers and employers. Raising or removing the taxable earnings cap would place a larger share of the additional financing responsibility on higher earners.
Increasing the retirement age would affect future beneficiaries by changing when they can receive their full scheduled benefit. A change to COLA calculations could reduce the pace at which benefits increase over time.
Lawmakers could also combine several measures instead of relying on a single change. For example, a smaller payroll-tax increase could be paired with changes to the taxable earnings cap or benefit rules.
The central issue is the projected difference between Social Security’s future revenue and scheduled benefits. With the retirement trust fund projected to face depletion in late 2032 under current law, the size, timing and combination of any changes would determine how the financial burden is distributed among workers, employers, higher-income Americans and future beneficiaries.
