Introduction

This webinar will review the latest state guidance on the taxation of C corporations. Our panel of seasoned SALT professionals will review states’ treatment of federal provisions, evolving interpretations of Public Law 86-272, and standard apportionment methods. They will provide practical strategies to mitigate tax and risk for C corporations operating in multiple states.

Description

C corporations are taxed separately and apart from their owners. These corporations are also subject to double taxation, once at the corporate level and again when dividends are distributed to shareholders. These differences from flow-through entities create unique planning considerations and issues for multistate corporations. 

Determining whether a business has nexus in particular states is critical. State legislation regarding nexus determinations, nexus-creating activities, and exceptions under Public Law 86-272 is volatile and varies from state to state. Additionally, apportionment methods, factors, and specific activities that create nexus must be understood to allocate and apportion income by state properly. Tax practitioners advising C corporations need to be cognizant of the latest legislation to comply with state-specific guidelines.

Listen as Lindsay and Marc explain state taxation of C corporations, including federal conformity, income allocations, and practical applications and tips for businesses and advisers of multistate C corporations.
