Dear Kitty,
I purchased a 10-year T Note in early 2024 with a premium on Vanguard secondary market. In the 1099 int form I received, Vanguard included the bond premium covered lots. Treasury note interest is taxable for federal income tax, but is exempted from state and local income tax. (And we don't pay state and local income tax anyway since we live in Texas.) Hence I am not sure whether we must amortize the premium I paid annually? (It it true that tax exempt bond must be amortized every year?) Or can I deduct the premium when the bond matures in 10 years or when I sell it later?
If I have to amortize this premium, do I also have to amortize the discounts on the rest T notes and T bonds we purchased/own as well then?
Thank you for your help
