Reference computation

For a North Carolina pass-through entity with $500,000 of qualified net income allocated to this state, at a 37% federal marginal bracket, the entity-level PTET and federal-deduction math is:

North Carolina — reference example

QBI allocation·NC rate= Entity-level tax

$500,000×4%=$19,950

N.C. Gen. Stat. § 105-154.1 (Taxed Partnership election); § 105-131.1A (Taxed S Corporation election)

Entity tax·Federal bracket= Federal deduction (gross)

$19,950×37%=$7,382

At a 37% federal bracket, the entity-level deduction saves $7,382 in federal tax. Net of §199A QBI offset (~20% × bracket × entity tax = $1,476), aggregate benefit is approximately $5,905.
