Federal law may protect remote sellers from state net income taxes

Behind the landmark U.S. Supreme Court case South Dakota v. Wayfair that now allows states to levy sales and use taxes on remote sellers with “economic nexus” lurks a similar, yet distinct, issue with respect to state corporate net income taxes.  Sales taxes are levied on transactions, in contrast to corporate net income taxes that are imposed for the privilege of doing business in a particular state.  The difference may seem inconsequential at first blush, but different factors matter when analyzing whether a business triggers nexus for state income tax purposes as opposed to sales and use tax purposes.  

Public Law 86-272

Known today as Public Law 86-272, Congress enacted the Interstate Income Act in 1959 in response to two U.S. Supreme Court cases allowing states to impose net income taxes on businesses with limited in-state activity.¹  P.L. 86-272, in relevant part, provides the following: 

No State, or political subdivision thereof, shall have power to impose, for any taxable year ending after September 14, 1959, a net income tax on the income derived within such State by any person from interstate commerce if the only business activities within such State by or on behalf of such person during such taxable year are either, or both, of the following:

(1) the solicitation of orders by such person, or his representative, in such State for sales of tangible personal property, which orders are sent outside the State for approval or rejection, and, if approved, are filled by shipment or delivery from a point outside the State; and

(2) the solicitation of orders by such person, or his representative, in such State in the name of or for the benefit of a prospective customer of such person, if orders by such customer to such person to enable such customer to fill orders resulting from such solicitation are orders described in paragraph (1).

In short, P.L. 86-272 prohibits states from levying net income taxes on businesses with in-state activities limited to soliciting orders for tangible personal property and fulfilling those orders by shipment or delivery from a point outside the state.  By enacting this statute, Congress implicitly weighed-in on the boundary line as to where a corporate net income tax is constitutional and where it may not be.   

Issues Persist

Fast forward 70 years and there is far different business landscape and legal environment for business than there was in 1959.  The South Dakota v. Wayfair case in 2018 now allows states to levy sales and use taxes on remote sellers regardless of whether they have an in-state physical presence.  So long as remote sellers have a threshold number of in-state transactions or amount of revenue generated from in-state consumers, they could trigger use tax collection duties.
