What does the due process clause require of taxes
Interstate Taxation and the Commerce Clause
The issue: What limitations does the Commerce Clause (and, to a lesser extent, the Due Process Clause)
place on how states can tax interstate businesses?
It is always poular tax strategy to shift the tax-burden as much as possible to out-of-state residents and corporations. Legislators would much prefer to tax non-voters than voters. Unsuprisingly, however, the Constitution imposes limitations on the ability of states to shift tax burdens to out-of-state corporations.
Since the 1977 case of Complete Auto Transit v Brady. the Court has used a four-part test to evaluate the constitutionality of taxes burdening out-of-state interests (see test in left column).
In Commonwealth Edison v Montana (1981), the Court considered the constitutionality of a 30% severence tax that Montana--America's "Saudi Arabia" of low sulfur coal--imposed on removed coal. Most of the coal came from federally owned land. About 90% of the coal was for shipment out of state. The Court's primary focus was on the fourth prong of the Complete Auto Transit test, requiring that the state show the tax is "fairly related" to services the state provides the taxpayer. The Court, noting certain state benefits received by Commonwealth Edison, found the test met. Three dissenters argued that the Commerce Clause was violated whenever states asked interstate commerce to bear more than their fair share of the tax burden-- which this tax, they believed, did.
In Quill Corporation v North Dakota (1992), the Court looked at a North Dakota "use" tax
applied to sales by out-of-state corporations (primarily catalog companies such as L. L. Bean and Land's End) to North Dakota residents. Quill Corporation raised several constitutional objections to the tax. Although the Court found Quill's mailing catalogs into a state was sufficient to satisfy the "minimum contacts" test for due process purposes, it was NOT sufficient to satisfy the "substantial nexus" requirement of Complete Auto Transit. The Court noted that Quill had no physical presence in North Dakota--no salespersons, no outlets, no warehouse, no office. In dissent, Justice White argued that it was silly to make a state's ability to tax depend upon whether or not a corporation has one travelling salesperson in the state, but the majority saw advantages in a bright line "physical presence" test.

Oklahoma Tax Comm'n v Jefferson Lines (1995) focused on the "fair apportionment" prong of the Complete Auto Transit test. Oklahoma imposed a sales tax on Jefferson Lines for the full cost of every bus ticket sold in Oklahoma, regardless of where the trip ticketed started or ended. Jefferson Lines argued that the Commerce Clause prohibited Oklahoma from imposing a sales tax on that portion of the ticket reflecting the cost of miles travelled outside of Oklahoma. The Court disagreed, viewing that sale of the ticket as "a discrete event facilitated at the point of sale." In dissent, Justices Breyer and O'Connor argued that Oklahoma must apportion its tax to the percentage of miles of the trip on Oklahoma roads.Source: law2.umkc.edu
