Question 1

What types of interest income are fully taxable?

Accepted Answer

Ordinary interest from bank accounts, CDs, corporate bonds, and savings accounts is fully taxable at federal and state levels. It is taxed as ordinary income at your marginal rate (10-37% federal).

Question 2

Are municipal bond interest payments tax-free?

Accepted Answer

Municipal bond interest is generally federal tax-free. If you buy bonds from your home state, they are also state tax-free. However, private activity bonds may be subject to Alternative Minimum Tax (AMT).

Question 3

How are Treasury bonds taxed?

Accepted Answer

US Treasury bills, notes, and bonds are subject to federal income tax but are exempt from state and local income taxes. This makes them attractive for residents of high-tax states.

Question 4

Does municipal bond interest affect Social Security taxation?

Accepted Answer

Yes. Municipal bond interest is included in your "combined income" used to determine how much of your Social Security benefits are taxable. This can push more of your benefits into taxable territory.
