Meaning

So, what is the Social Security tax cap exactly? In simple terms, it’s the maximum amount of income that’s taxed for Social Security each year. If you earn more than the cap, anything over $176,100 won’t get hit with the 6.2% Social Security tax—but Medicare taxes still apply.

How does the tax play out based on your work situation?

• Employees: You pay 6.2% on earnings up to $176,100, and your employer matches that.
• Employers: They pay the same 6.2% for each employee.
• Self-Employed: You wear both hats—so you pay 12.4% yourself. Good news though: half of this is tax-deductible.

It’s all about keeping the Social Security system funded while matching wage growth and inflation.
