Tax professionals, particularly those new to state corporate income tax compliance, require a sturdy grounding in the similarities and differences and latest trends in state approaches and formulae for apportioning a company's income.

Grasping the role of sales, payroll and property factors and developing an awareness of the single-sales formulae are a strong start. Tax pros must also learn the differences between Joyce and Finnigan rules, market-based and cost-of-performance sourcing, and definitions of carryback and throwout.

The recent Gillette case and 2013 state bills are reshaping the apportionment landscape. An explanation of essential multi-state concepts governing apportionment of income will position newer tax specialists at companies and accounting firms to work more effectively.

Our panelists, recruited from top experts in the industry, will prepare tax staff with a review of key apportionment concepts and trends needed for working on state income tax compliance for multi-state companies.

The panel will explain these and other important topics:

• Factor-weighting in apportionment formulae, and the latest snapshot of single-sales states.
  
  
• Cost-of-performance and market-based sourcing rules.
  
  
• The practical differences between a Joyce and Finnigan state.
  
  
• States that employ carryback and throwout provision—and what they mean for corporate taxpayers.
