I had interest income in n.c. not shown on my return?
It depends on where you are looking on your North Carolina tax return. Ordinary interest reported on form 1099-INT from North Carolina sources would be included on Form D400 Line 6 Federal AGI and be included in North Carolina taxable income.
Interest on notes and bonds from North Carolina sources are not taxable to North Carolina and therefore are not included on the D400 tax return. Interest Not Taxable to North Carolina
