Final answer:
The total amount of social insurance taxes on a $65,000 salary is $4,972.50, which includes both Social Security tax ($4,030.00) and Medicare tax ($942.50).
Step-by-step explanation:
To calculate the total amount of social insurance taxes that you will be responsible for after your first year of work with an annual salary of $65,000, you need to consider both Social Security and Medicare contributions.
Social Security taxes are calculated as 6.2% of your gross annual income. On a $65,000 salary, the Social Security tax would be:
0.062 × $65,000 = $4,030.00
The Medicare tax rate is 1.45% of your gross annual income. So, for a $65,000 salary, the Medicare tax would be:
0.0145 × $65,000 = $942.50
To find the total amount of social insurance taxes, we just add the amounts for Social Security and Medicare taxes:
$4,030.00 (Social Security) + $942.50 (Medicare) = $4,972.50
Therefore, the total amount of social insurance taxes you will owe is $4,972.50, which makes the correct answer (a) $4,972.50.
