Kelly Zack, MST

Director, State & Local Tax

Kelly is a senior leader in AAFCPAs’ Commercial Tax practice. She advises individuals, partnerships, corporations, and trusts operating in multiple states and municipalities on opportunities to save tax dollars through advanced tax planning and risk mitigation. She enthusiastically assists AAFCPAs clients in identifying all location-specific tax incentives and credits which could have a major impact on business entities and their owners.

Kelly has deep expertise providing: nexus analysis for income/franchise tax and sales & use taxes; analysis of state and local tax aspects related to the purchase and sale of businesses; review of potential tax exposure in support of financial statement reporting under FIN 48; review of prior year state and local tax returns for potential refunds; review of payroll and pass-through entity withholding requirements; evaluation of internal accounting processes used to capture data required for multi-state and local tax compliance and planning; and sales tax compliance studies.

In addition, Kelly evaluates voluntary disclosure and amnesty programs, assists with formal and informal ruling requests, and provides sophisticated state and local tax audit representation, as needed.

As state and local needs for new revenue sources have grown nationwide, government entities have become increasingly aggressive in pursuing new taxation opportunities wherever possible. Kelly leverages her deep knowledge of tax strategies and structures to help clients effectively manage and plan for the continuously evolving complexities of multistate taxation—and avoid penalties associated with noncompliance.
