1. Federal income tax: $3,062

| Taxable income band | Rate | Income taxed | Tax |
|---|---|---|---|
| $0 to $12,400 | 10% | $12,400 | $1,240 |
| $12,400 to $50,400 | 12% | $15,180 | $1,822 |

3. Social Security and Medicare: $3,342
Social Security is 6.2% of wages up to the $184,500 wage base ($2,708), and Medicare is 1.45% of all wages ($633).
Result: $43,680 minus $8,420 in total tax leaves $35,260 a year, an effective tax rate of 19.3%.
