Final answer:
Kathy should expect to pay $12,441 in taxes every year.
Step-by-step explanation:
To calculate Kathy's federal income tax, we need to multiply her annual income by her net federal income tax rate. Kathy's annual income is $66,000 and her net federal income tax rate is 18.85%
So, the amount Kathy should expect to pay in taxes every year is $66,000 * 0.1885 = $12,441.
Therefore, Option 2: $12,441 is the correct answer.
