E-commerce offers customers the chance to eliminate many stages in the sales/distribution chain. The mark-ups that occur between manufacturers, wholesalers, distributors, retailers and consumers can add the cost of goods purchased by consumers. In contrast, when consumers deal directly with manufacturers on the internet, the process whereby intermediaries between the manufacturer and the final consumer are eliminated from the supply chain is known as "disintermediation".

E-commerce differs from mail order and telephone solicitation, the two most traditional forms of business using remote sellers, because these involve the delivery of goods by common carrier to and from a specific physical location. In short, there is still a physical delivery of property from an identifiable seller to an identifiable buyer. States jurisdictions have wrestled with the issue of collecting taxes from out-of-state mail order sellers and telephone solicitors for decades; e-commerce enables almost any business large or small to sell to customers in different states and countries.

Out-of-state vendors engaged in e-commerce do not have an obligation to collect sales taxes if traditional remote sellers, such as mail-order and telephone solicitation vendors, do not collect sales taxes. Sales tax cannot be levied on a transaction just because the purchaser uses e-commerce to access the seller's computer to acquire property, goods or service. Also, states cannot use an "agency nexus" theory to claim that a purchaser's ISP is an in-state agent for the seller.

Commerce Defies Traditional Tax Jurisdictions

Using the internet, a company can, in theory, move its e-commerce business to a tax-haven country and conduct e-commerce outside the jurisdiction of any country that would otherwise tax the transaction.

Also, because of the speed in which transactions occur and the frequent absence of a traditional paper trail, it will be very difficult, if not impossible, to apply traditional notions of tax jurisdiction. This is especially true with intangible property transmitted by computer such as software, digital music or electronic books and services.

While governments which depend on an income tax might have difficulty taxing e-commerce, states and local jurisdictions that rely on sales and property taxes to fund their operations could be in deeper trouble.

Lack of a Paper Trail

Unless a tangible product is delivered by common carrier, it is impossible for a taxing jurisdiction to determine that an e-commerce transaction occurred. For instance, if a consumer downloaded a computer game from a computer located in a foreign country for $19.95, paying by credit card, how would a taxing jurisdiction discover that such a transaction occurred? How would it determine the physical location of the seller? What if the purchaser had an internet service provider (ISP) in a foreign country as well?

Transmitting Property from Tangible to Intangible

Consider the following issues: Would the receipt of a computer game in electronic form convert the game into a non-taxable intangible item, whereas the purchase of the same game at a local computer store would be taxable because it is a tangible product?

Also, if a newspaper has an exemption from sales tax will a newspaper that is downloaded in electronic form receives the same exemption? If not, would the tax levied on the electronic version of the newspaper be a discriminatory tax in violation of the commerce clause?

E-cash Issues

Electronic money is a type of debit card similar to a telephone calling card where the card itself keeps track of the remaining balance, rather than a third party bank. This could emerge as the preferred medium of exchange for e-commerce. E-cash will have the same anonymity as cash does in the current "underground" economy. Use of e-cash will further frustrate states and local jurisdictions on taxing e-commerce.

Multiple Taxes

Multiple taxes on the same transaction or service, either in the same taxing jurisdiction or two or more taxing jurisdictions, are prohibited. This could occur if a state-taxed internet access services as telecommunications and then taxed located telephone services as well. Unless a credit is given to eliminate any double-taxation, such a tax would violate the prohibition against multiple taxes.
