Sen. Bernie Sanders has drawn attention to the Social Security system, stating that Elon Musk, now a trillionaire, contributes the same amount to Social Security as an individual earning $184,500 annually.
This observation stems from a specific aspect of the Social Security program: a cap on taxable income. Currently, Social Security taxes are only levied on wages up to a certain threshold. For 2026, this limit is set at $184,500. Any income earned above this amount is not subject to Social Security taxes.
Sanders plans to introduce legislation aimed at addressing this “absurdity” by removing the income cap. He argues that such a change would not only ensure Social Security’s solvency for 75 years but also allow for an expansion of benefits by $2,400.
The debate intensified following Elon Musk’s achievement of becoming the world’s first trillionaire. This milestone has reignited discussions about wealth disparity and the tax obligations of the ultra-wealthy.
The Social Security tax structure, where both employees and employers contribute 6.2% of wages up to the annual limit, means that the maximum an individual employee contributes in 2026 is $11,439. For self-employed individuals, this amount doubles to $22,878. Crucially, individuals earning significantly more than $184,500, whether $200,000 or millions, do not incur additional Social Security taxes on income exceeding the cap. Furthermore, these higher earnings do not translate to increased future Social Security benefits.
Labor economist Teresa Ghilarducci has pointed out that the maximum Social Security tax paid is effectively the same for someone earning $184,500 and for the nation’s wealthiest individuals.
While Sanders’ assertion that Musk pays the same amount into Social Security as someone earning $184,500 is largely accurate due to the tax cap, a nuance exists. It’s not guaranteed that Musk consistently pays the maximum Social Security tax each year, as a significant portion of his wealth derives from investments rather than a traditional salary. Social Security taxes apply specifically to wages and certain forms of compensation like stock options, but not to investment income such as capital gains.
Publicly available information indicates that Musk does not draw a salary from Tesla. While a filing prior to SpaceX’s public offering showed a salary of $54,080 from that company, compensation details from his privately held ventures are not disclosed. In instances where Musk has exercised stock options, such as in 2021 generating over $20 billion in taxable income, his Social Security tax liability was still capped by the program’s limits.
