a) For the year 2018, the employee's portion of the FICA tax is 7.65% (the Social Security tax of 6.2% plus the Medicare tax of 1.45%) on the first $128,400 of an employee's salary and wages. On an employee's salary and/or wages in excess of $128,400 the employee's portion of the FICA tax is 1.45%
| Rory's total FICA taxes: | $0 |
| Latesia's total FICA taxes: | $9,990.80* |
* for $128,400 @ 7.65% and remaining $11,600 @ 1.45%
b)
| MARGINAL TAX | TAX RANGE | TAX |
| 10% | $0-$9,525 | 10% of your taxable income |
| 12% | $9,525-$38,700 | $952.50 + 12% of the amount over $9,525 |
| 22% | $38,700-$82,500 | $4,453.50 + 22% of the amount over $38,700 |
| 24% | $82,500-$157,500 | $14,089.50 + 24% of the amount over $82,500 |
| Rory's marginal tax rate: | 22% |
| Latesia's marginal tax rate: | 24% |
c)total taxes to be paid by Rory $4,453.50+ ($70,000-$38,700)* 22% = $11,339.50
Average rate $11,339.50/$70,000 = 16.20%
total taxes to be paid by Latesia $14,089.50 + ($140,000-$82,500)* 24% = $27,889.50
Average rate $27,889.50/$140,000 = 19.92%
| Rory's average tax rate: | 16.20% |
| Latesia's average tax rate: | 19.92% |
d) Effective tax rate is total tax / taxable income
total tax = income tax + FICA
| Rory's effective tax rate: | 16.20% |
| Latesia's effective tax rate: | 27.05% |
