NC requires you to have the same State of Residence as your active duty spouse in order for your income to not be taxable by NC.  (See the reference provided by @JosephF8 .)

The new MSRRA law allows you to choose your active duty spouse's Home of Record (HOR) as your State of Residence for tax filing purposes, even if you've never lived there.  (You can also choose your own domiciliary state if you prefer - it's your option.)  

SO, if you want your income not to be taxable by NC, enter your spouse's HOR as your State of Residence in the My Info section of TT.  

NH doesn't have an income tax, but if you enter NH as your State of Residence, and your husband's HOR is some other state,  your income would become taxable by NC.
