NC part-year tax forms work similarly...and you can't know whether you've done it right without looking at the NC D-400 and D400-Schedule PN
...they use total NC taxable income first: line 12b of the D-400
...then calculate a decimal amount that refers to NC only BASED on yoru income allocations during the NC interview (line 13 of the D-400)
.... line 13 x line 12b give you line 14...the final NC taxable income for which the tax is calculate.
___________________________
Print out copies of both state forms and look at them first, then re-do each of the state interview steps if they still seem way off.
