Before filing your North Carolina return, review it to make sure it is complete and correct. The following questions may help you avoid errors that could delay your refund.
- Did you attach copies of all W-2 Forms and other statements to verify your North Carolina income tax withheld?
- Did you enter the correct amount of North Carolina income tax withheld on the return? Check to be sure you did not mistakenly enter your federal income tax withheld, social security tax, or state tax withheld but paid to another state.

- Did you enter the correct amount of federal adjusted gross income as the starting point for your North Carolina return? The starting point for the computation of North Carolina taxable income is federal adjusted gross income.
- Did you erroneously enter zero as the starting point for the return? Enter your federal adjusted gross income from your federal return on line 6 of Form D-400. If federal adjusted gross income is a negative number, enter the negative amount and fill in the circle to indicate that the amount is negative. (Note: If you are completing a web-fill-in form on the Department’s website, enter a minus sign to indicate a negative number.)
- Did you have any additions to federal adjusted gross income? If yes, you must complete and attach D-400 Schedule S, Part A, Additions to Federal Adjusted Gross Income. The total additions entered on Form D-400 Schedule S, line 6, also needs to be entered on Form D-400, line 7.
