ON-DEMAND WEBINAR

As businesses expand and deliver products and services across state lines, understanding multi-state apportionment and revenue sourcing rules is critical for reducing and mitigating multi-state tax compliance risk, while managing the company’s effective state tax rate. Additionally, differences in apportionment formulas, revenue sourcing rules, and classifications of particular revenue streams can significantly impact multi-state gross receipts, franchise, and net income tax liabilities. 
 
Watch members of CohnReznick’s State and Local Tax Team for a practical overview of multi-state apportionment fundamentals and updates, including administrative and case law developments on how market sourcing, cost of performance and income-producing activities methodologies have been applied by taxpayers and state taxing authorities. We’ll also explore alternative apportionment methods, specialized apportionment formulas for certain industries, and how to practically apply market sourcing rules for optimal results.

In this webinar, participants will be able to: 

• Identify the core principles of multi-state income tax apportionment and how they apply across jurisdictions 
• Distinguish between market sourcing, cost of performance and income-producing-activities sourcing methods and their multi-state tax implications 
• Identify opportunities for applying specialized industry formulas or alternative apportionment methods 
• Recognize when look-through versus non-look-through situations apply in the context of market sourcing rules applied to services where a third party may receive the benefit of the service
