Program Materials

This webinar will prepare tax staff for state income tax compliance by multi-state companies with a review of key apportionment concepts, relevant court decisions, and new state laws and proposals.

Description

Tax professionals, particularly those new to state corporate income tax compliance, require a sturdy grounding in the similarities, 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 approaches to income apportionment, market-based and cost-of-performance sourcing, and definitions of carryback and throwout.

Gillette Co. v. Franchise Tax Bd. (the Supreme Court denied cert. Oct. 11, 2016, leaving the California Supreme Court’s ruling intact), other recent state court rulings, and state legislation 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.

Listen as our panel of experienced tax advisers provides a fundamental overview of the most essential concepts in state apportionment of business income for taxation.
