Which is why what you pay in FICA taxes does not determine the lifetime benefits you receive.
FICA — The Tax Law
Federal Insurance Contributions Act (FICA) was enacted as part of the Internal Revenue Code
- Passed in 1935 alongside Social Security, but it is a tax statute
- It lives in the tax code and is enforced by the IRS
- It simply authorizes the government to collect the payroll tax
- Governs the how much and who pays questions
Social Security Act — The Benefits Law
The Social Security Act was signed by FDR on August 14, 1935
- A completely separate piece of legislation
- Establishes the benefit program itself
- Governs who qualifies, how benefits are calculated, and how they’re paid out
- Administered by the Social Security Administration (SSA), not the IRS
Why This Distinction Matters
This separation has a very significant legal consequence — the Supreme Court settled this early on:
In Flemming v. Nestor (1960), the Supreme Court ruled that workers have no contractual or property right to Social Security benefits just because they paid FICA taxes. Congress can legally:
- Change benefit formulas
- Raise the retirement age
- Reduce or restructure benefits
- Even theoretically eliminate the program
Your FICA taxes do not create a legal entitlement the way a private pension or savings account would.
