The Hard Part Is Usually the Interaction Between States

Residency, remote work, pass-through income, rental property, state credits, withholding, sales-tax nexus, and entity elections can each follow different sourcing rules. Our multi-state work starts with a fact map—where you live, work, own property, employ people, and earn revenue—before calculating any return.
