Your employer pays half (6.2% FICA, 1.45% Medicare) and you pay half (6.2% FICA, 1.45% Medicare).
You pay your half by having it deducted from your check. Since I can't see your amounts, I'll make some up:
Say you made $100. You would have 6.2% FICA and 1.45% Medicare tax withheld, so you would receive
100-6.20-1.45 = 92.35.
Your employer would pay the government its share, $7.65 plus your $7.65, for a total of $15.30.
They just showed it on your check like that.
If you still think there's something wrong, post back to this thread and I'll help you.
