Why the rate falls

Social Security stops at the wage base, so profit above it is charged 2.9% Medicare rather than 15.3%. That is why the effective rate at $250,000 of profit is 11.8% and not the 15.3% almost everyone expects. The additional Medicare surcharge of 0.9% pushes back in the other direction above its own threshold, but not far enough to reverse it.

Where this comes from: set by statute, not adjusted annually · IRC §3101(b)(2) (wages); IRC §1401(b)(2) (self-employment income).

The half you can deduct is the other thing routinely missed: it comes off adjusted gross income, so it lowers income tax without lowering the self-employment tax itself.
