This webinar will explain the throwback and throwout rules with practical examples of how these calculations are made. Our panel of state and local tax professionals will discuss nexus, apportionment allocations, and how SALT planning should incorporate these rules for businesses with sales transactions in multiple states.


The varying apportionment formulas in states can lead to disproportional allocations of state income tax. In addition to these, 22 states impose throwback rules, and three have throwout rules. Adding this to the mix often results in even greater distortions of state income tax paid by businesses.

Throwback rules tax sales of tangible property in the state the sale originated, whether or not the income was earned in this jurisdiction, when the sale is not taxable in the destination state due to lack of nexus. Proponents believe these rules ensure that companies do not avoid taxation on this "nowhere income."

Often overlooked but undoubtedly crucial, the impact of these rules should affect the business location and investment decisions made by companies operating in multiple states.

Listen as our panel of SALT experts discusses the states imposing these rules, how the calculations are made, the interaction of Public Law 86-262 with the throwback rules, and planning opportunities that exist when coordinating sales in multiple jurisdictions.
