The Social Security program faces a significant challenge, with forecasts suggesting its funding may be depleted by 2034. This looming crisis has sparked extensive debate regarding potential remedies. A consensus is emerging among experts that increasing the program's income, rather than cutting benefits, represents the most desirable path forward.
One novel proposition being considered involves imposing taxes on employer-provided health benefits. Currently, the primary source of Social Security's revenue is payroll taxes, which apply to income up to a certain threshold, set at $176,100 for 2025. Benefits such as health insurance, retirement plans, and disability coverage are generally exempt from federal income and payroll taxes.
A recent study from the Center for Retirement Research at Boston College indicates that integrating employer-sponsored health insurance (ESI) into the Social Security taxable wage base would undeniably provide a financial uplift. Analyzing 2021 tax data, the study revealed that such a measure would have increased the average tax burden by $420 annually per worker, translating into an additional $70 billion in revenue for Social Security. However, this approach could disproportionately affect lower-income workers.
To mitigate the potential negative impact on low-income individuals, experts suggest implementing a tax on health benefits only for those whose annual income surpasses a specified threshold, mirroring the existing earnings cap. This modification aims to balance the need for increased revenue with the protection of vulnerable workers.
The report also contrasted the effects of taxing health benefits with a more traditional approach: raising or eliminating the earnings cap for payroll taxes. Eliminating this cap entirely would have generated an average annual increase of $1,330 in Social Security contributions in 2021, tripling the revenue boost to approximately $220 billion compared to taxing ESI.
Despite the substantial potential of adjusting the payroll tax cap, experts emphasize that this alone may not suffice to secure Social Security's future. The disproportionate growth in earnings between high-wage and low-wage workers has led to a shrinking share of total earnings subject to payroll tax, from 89% in 1985 to 83% in 2023. Therefore, a multi-faceted strategy, combining an increased payroll tax cap with other revenue sources like ESI taxation, is deemed essential for ensuring the program's longevity and stability.
