Reference computation
For a New Mexico 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:
At a 37% federal bracket, the entity-level deduction saves $10,915 in federal tax. Net of §199A QBI offset (~20% × bracket × entity tax = $2,183), aggregate benefit is approximately $8,732.
