A quick example

If your 2023 wages were:

  1. 120,000 dollars: you’d pay 6.2% of 120,000 (7,440 dollars) in Social Security tax.
  1. 160,200 dollars or more: you’d hit the cap and pay the full 9,932.40 dollars for the year.

In plain terms, once your 2023 earnings for Social Security reach 160,200 dollars, additional wages are not charged the 6.2% Social Security tax, though Medicare taxes continue without a similar cap.

TL;DR: The answer to “what is max Social Security tax for 2023” is 9,932.40 dollars for employees (double that—19,864.80 dollars—if you are self‑employed, since you pay both sides).
