Article: 50663

North Carolina conforms to the federal tax law as it existed on January 1, 2023. The federal tax law changes passed July 4, 2025, do not apply when calculating North Carolina income tax. As a result, you may need to add back or adjust the AGI amount that is carried from the federal return to the NC return. See the NC DOR Notice for details.

In 1040.com, adjust the AGI that is used for NC purposes by following these steps.
