How is Social Security financed?
Social Security is financed through a dedicated payroll tax. Employers and employees each pay 6.2 percent of wages up to the taxable maximum of $176,100 (in 2025), while the self-employed pay 12.4 percent.
Total income, including interest, to the combined OASI and DI Trust Funds amounted to $1.351 trillion in 2023. ($1.233 trillion from net payroll tax contributions, $51 billion from taxation of benefits, and $67 billion in interest)
US Social Security Expenditures in 2023: $1.351 trillion.
Do you see income taxes in there other than those from recipients?
I won't dirty up this post further, but Medicare is likewise funded; like SS, income taxes on Social Security benefits do go partially to fund Medicare, as those people are generally program recipients. The final funding source is Part A premiums.
I don't mind banter or disagreements, but please do not tell me I'm wrong when you have not even bothered to look. Your gut feeling is not a good basis to dispute someone's premise.
