Distinguish between income tax and payroll tax and their roles in funding government programs.

• A. They are the same thing.
• B. Income tax is on earnings; payroll tax is dedicated to Social Security/Medicare; both reduce take-home pay.
• C. Income tax is optional; payroll tax is optional.
• D. Payroll taxes fund Social Security and Medicare, while income taxes fund general government programs.

Answer: (B)

The main idea is that taxes come from earnings in two distinct ways that fund different government functions. Income tax is levied on earnings and funds general government operations and programs, not tied to a specific program. Payroll tax, on the other hand, is earmarked for Social Security and Medicare, with the amounts withheld directly from wages to support those programs. Both taxes reduce your take-home pay, but they serve different purposes: payroll taxes support the social programs, while income taxes fund a broad range of government activities. That combination is why the statement that income tax is on earnings, payroll tax goes to Social Security/Medicare, and both reduce take-home pay best captures the distinction.
