Where do you see this? NH is listed in the list of states you have there in between MA and NJ.
When I select "Learn More", NH is not listed.
Learn More says:
If your state isn't listed, leave the special handling box blank. We'll cover interest when you get to your state return.
Maine
Maryland
Massachusetts
New Jersey
West Virginia
I took a screenshot if you want me to email it to you.
NH is initially listed because it does not tax all interest but beyond not taxing specific sources of income NH only taxes interest and dividends that exceed 2400 (4800 for joint filers). Since there will be special handling beyond simply identifying the source as non-taxable, everything will be handled in the NH state interview vice the federal interview.
what is special about these six states. It comes up with regard to interest on treasury bills but interest on treasury bills is state tax exempt in every state. So what's special about these 6 states???
These six states handle certain types of interest differently than most. If you click the "Learn More" link that appears next to the statement about the six states, more information appears with instructions specific to each of those states.
See this TurboTax tips article for more information about reporting interest income.
Unfortunately, this doesn't answer my question. For example, all states, ALL STATES, exempt interest on treasury bills yet this interview page suggests that anyone in a state not mentioned need not check the box????
Box 3 Treasury Obligations are all state exempt so the program doesn't ask about them. The 6 states have special rules for other interest calculations.
