@lion_cpa: Sorry you felt unwelcome, I don't think that is anyone's intention. Regarding this post, the way you ask the question is kinda funny…it's a very basic question that can be answered by just reading your book (most likely the first chapter). Maybe that's why James & Mini commented the way they did. Don't take it too seriously, they mean well…all of us do:)
And to answer your question: Pretty much everything is taxable unless it specifically excludes it, some of those excluded things are:
-State and Local gov't bonds/obligations,
-Bonds of US possession,
-Series EE if used for Educational expenses,
Veterans Admin. Insurance.
So pretty much all bonds are taxable (unless it's State/Local/US possession)…bonds such as federal bonds, corporate bonds are taxable!!
Hope that helps & I hope you stick around…there's lot that can be learned from others. Good Luck!
