The question is simply this:

Is the Accrued Market Discount for a US Treasury Note reported in Box 1f of Form 1099-B state income tax exempt?

I am particularly interested for the answer with respect to the state of New York, but I welcome any informed information especially if it is from a professional who has first hand experience with  and knowledge of the correct answer.

I ask that anyone who responds please avoid posts that speculate about the answer.  I am seeking not speculation or academic debate, but a response from someone (hopefully a professional) who knows first hand from experience how this is routinely handled in the real world.

Thank you for any solid information.
