@Bsch4477 - I suspect, but not 100% confident, that relates to corproate income tax; not personal incoem tax. That paragraph talks about 'net income' and that is not an expression used on an NC personal tax return.
I can tell you that the NC tax return simply begins with Federal AGI (LIne 11) with very, very few adjustments that either add or subtract from AGI. The typical reductions are taxable portion of SS, certain public pensions, military pensions and interest on federal obligations , which are all not taxed in NC. The typical additions are debt cancellation on student loans (a variance through 2025) and personal residences, which are taxable in NC even though they are not taxable on the federal return.
There is no adjustment for tax loss carryforwards.
that is really it; the NC return is quite simple - with one tax bracket: - it's a flat tax (4.75% in 2023) after a standard deduction and child deduction.
