2026's Social Security Shift: A Market Test of Fiscal Reality

The adjustments to the tax structure reveal a deeper flaw. The taxable maximum will increase to $184,500, meaning a larger share of wages is now subject to the payroll tax. On the surface, this appears to strengthen the system's revenue. In reality, it highlights a critical design weakness. The payroll tax is levied only on earned income up to a cap, leaving investment income and other non-wage earnings untaxed. By raising the cap, the system captures more revenue from high earners but does not address the fundamental issue of taxing a growing portion of the economy that is not covered by the payroll tax base.
