A Brief Introduction to Tax Nexus

Friday, February 5, 2010 by Rebekah Lu
With all the affiliate nexus bills that have been introduced lately in legislatures across the country I thought it might be interesting to take a look at where the concept of tax nexus comes from. Nexus is a Constitutional concept. Traditionally the "dormant Commerce Clause" protects sellers with no in-state presence from being obligated to collect sales or use tax. But, what is the dormant Commerce Clause?

The Commerce Clause: The U.S. Constitution gives Congress the power "to regulate commerce with foreign nations and among the several states..."

The dormant Commerce Clause: If Congress has not exercised its power, state and local governments are free to regulate local aspects of interstate commerce such as by imposing a tax on an out-of-state vendor.

If a state chooses to act under the dormant Commerce Clause the regulation must meet two requirements:

1) it must not discriminate against out-of-state competition, and
2) it must not be unduly burdensome.

Use taxes are not considered discriminatory even though they single out interstate commerce for taxation as long as the use tax rate is not higher than the sales tax rate.

A non-discriminatory use tax must also not be unduly burdensome. Three factors are generally looked at to determine this:

1) the existence of substantial nexus,
2) fair apportionment, and
3) fair relationship.

The first prong is the one that gets all the attention. A remote seller may only be subjected to use tax collection obligation if it has substantial nexus with the taxing state.

Q: How does a remote seller with no physical presence in a state get substantial nexus?

A: Through "attribution".

"Attributional nexus" is the nexus created when the physical presence or contacts of A are attributed to B in order to determine that substantial nexus exists. The crucial factor is whether or not the activities performed by A are significantly enough related to B's ability to establish and maintain a market in the state for sales. Is an affiliate related closely enough? We shall see.

This is very informative. Can you answer this question for me? If Company A has nexus in a CA and sells to Company B who then resales to the end customer in CA; Company B has no "physical presence in CA, but is owned 100% by one of the owners of Company A. Does this create nexus in CA for Company B?

Hi Angela, That is a very interesting and potentially complex situation. Here is my very general response based on the limited facts given. Prior to January 1, 1996 former Cal. Rev. and Tax Cd. Sec. 6203(g) did provide for nexus to be established by a situation like the one you describe. Under that law any retailer owned or controlled by the same interests that owned or controlled any retailer that was engaged in business in the same or similar line of business in California was considered to be engaged in business in the state. Since, that is no longer the case whether or not Company B has nexus in California would now depend on whether or not Company B itself meets the requirements for a "retailer engaged in business in the state" as defined by the current Sec. 6203.

Does having a service tech do a annual service on equipment in the state of Hawaii create nexus?
