What this means
On a salary of $40,000 you keep $32,928 — about 82% of what you earn. The remaining $7,073 is split across five separate deductions.
The largest is Social Security and Medicare at $3,060, roughly 43% of your total tax bill. Connecticut's own income tax takes $1,193, which is less than the $3,060 taken for Social Security and Medicare. The state payroll contribution adds $200 — small, but taken from every paycheck.
Your next dollar of income would be taxed at 16.5% once federal and state are combined, while the rate you actually pay across the whole salary is 17.7%. That gap is why a raise never feels as large as the headline rate suggests — and why the effective rate, not the bracket you land in, is the number worth comparing between states.
