Chicago Fed Letter
The debate on Internet
sales taxation
The advent and expansion of the
Internet have brought the issue of
the application of state and local
sales taxation to Internet, telephone,
catalog, and other “remote sales” to
the forefront of the policy debate.
Under current law, states cannot
require corporations without a substantial presence within their borders
to collect and remit sales taxes.
While all states do require residents
to remit the taxes owed in the form
of use tax payments, few people send
in use tax forms, rendering remote
sales essentially tax-free. The revenue
loss due to the lack of taxation on
Internet sales has been minimal thus
far; however, states are concerned that
the growth of the Internet will lead to
a substantial drain on revenue. In this
Fed Letter, I describe the debate on the
tax treatment of Internet commerce
and potential solutions the states
might pursue.
In 1998, general sales taxes were one
of the two largest sources of state
revenue, the other being the income
tax. In total, states received $156 billion
in general sales tax revenues, representing just below one-third of state
tax revenues. Revenue structures vary
dramatically from state to state (see
figure 1). While the average state sales
tax rate in January 2000 was 4.6%, sales
tax rates range from 0% (in Alaska,
Delaware, Montana, New Hampshire,
and Oregon) to 7.0% (in Mississippi
and Rhode Island). In numerous states,
localities charge additional rates.1 In
addition, states have different tax bases
or items that are subject to taxation.
Tax bases tend to vary along two dimensions. First, many states treat food
and drugs differently from other
goods by taxing them at a different

rate or by totally exempting them
from taxation. Second, all states
exempt some business to business
transactions because the sales tax is
intended as a tax on consumption.
During the past 25 years, state sales
tax bases have been rapidly declining.2 However, legislated increases in
sales tax rates have largely compensated for the declining base. The
combination of these two forces has
left the average revenue contribution
from sales taxes essentially unchanged
at 31% of total state tax revenues
for the past three decades (Census
Bureau data from Survey of State Government Finances). The decline in the
tax base has been attributed to three
factors: the growth in legislated exemptions for products such as food
and drugs; growth in consumption
in the largely untaxed service sector;
and the increase in remote sales.
Purchases in this last group are not
truly tax-free but taxes on them are
very difficult to collect.

All states with a sales tax have a corresponding use tax. The use tax requires state residents to pay the
equivalent sales tax amount on goods
purchased from vendors without a
state presence directly to the revenue
department. These purchases can
occur either when a resident is visiting a different state or nation or
when a resident makes a purchase
by mail, phone, or Internet. Use taxes
are notoriously difficult to collect from
consumers except on major items that
need to be registered in the home state
such as cars, boats, and airplanes. Businesses have historically been more likely
to pay their obligations motivated by,
in part, concern about use tax audits.
Taxation and remote sales
In a series of opinions, the Supreme
Court has ruled that states cannot
compel firms without a “substantial
nexus” within the taxing state to collect
and remit use taxes. (The most important cases are National Bellas

Hess, Inc. v. Department of Revenue
of Ill., 386 U.S. 753, and Quill Corp.
v. North Dakota, 504 U.S. 298.) “Substantial nexus” has been interpreted
to mean a physical presence, and
precludes states from requiring vendors
whose only connection to the state is
by mail, phone, or Internet to remit
taxes. In their 1992 decision in Quill,
the court ruled that requiring outof-state vendors to collect the use tax
created an unconstitutional burden
on interstate commerce because “[t]he
many variations in rates of tax, in
allowable exemptions, and in administrative and record-keeping requirements could entangle National’s
[the plaintiff] in a virtual welter of
complication obligations.” At the same
time, the ruling indicated that such
taxation is not unconstitutional per se
and would be permissible if authorized
by Congress.3 It is important to note
that the Supreme Court’s decision in
Quill only related to the ability of states
to compel vendors to collect and remit
use taxes; it did not render the use tax
itself unconstitutional.
The sales tax is widely viewed as
regressive. The exclusions for drugs
and food have been justified on the
grounds that they reduce regressiveness. However, the exemption for
Internet sales makes the sales tax
even more regressive because wealthier
people are far more likely to have Internet access. Figure 2 plots Internet use

situation is troubling, it is not in itself
sufficient reason to begin taxing Internet sales because states can (and do)
reduce the regressiveness of their
overall tax code through different
means, especially through changes
in the income tax.
The second issue with the lack of
taxation on Internet sales is that it
reduces the money available for state
provision of necessary government
services. Thus far, state losses have
been very minimal; Internet sales
represented just 0.64% of retail sales in
the fourth quarter of 1999.5 Estimates
of state tax losses due to e-commerce
vary from $170 million in 1998
(according to an Ernst and Young
report) to $1 billion in 1999 (National
Conference of State Legislatures).
Even the larger of these estimates is
very small when taken in the context
of the $475 billion in state tax collections in 1998. However, as the Internet
grows, so will state losses. In the most
comprehensive analysis of the revenues
that will be lost by state governments
due to e-commerce, Bruce and Fox
(2000) estimate that states will lose
approximately $10.8 billion in 2003
(see figure 3).
Some commentators argue that with
balances and revenues currently at
high levels, most states do not need
the money. While it may be true that
states can afford to cut their taxes,
this does not imply that allowing the
Internet to continue to be a tax haven
is the best use of tax reduction dollars.
States have a decent record of cutting taxes in the presence of excess
funds. State tax cuts in 1999 alone
reduced estimated total tax collections for FY 2000 by $7.2 billion or
1.7% of revenues.6
The third major issue with the lack of
sales tax is that it distorts numerous economic decisions, including consumers’
decisions on where and how to make
purchases and business decisions on
location and corporate structure.

consumers who do not plan to pay
their use tax may choose to purchase
an item on the Internet that they
would otherwise have bought from a
local retailer. In a careful analysis of
Internet sales, Austan Goolsbee of
the University of Chicago estimates
that applying sales tax to the Internet
would reduce the number of online
shoppers by 24%.8
The sales tax issue also gives firms an
incentive to locate in low population or
low tax jurisdictions so as to minimize
the taxes they need to pay on behalf
of their customers. While there is no
direct research on Internet firm location, some anecdotal evidence points to
a location effect. In an article naming
Amazon founder Jeff Bezos Person of
the Year, Time magazine writes of
Amazon’s warehouse in Coffeyville,
Kansas, “[h]alf a dozen warehouses
like it have been strategically placed
in low- or no-sales-tax states around
the U.S.”9
Firms also have an incentive to structure in order to minimize the number
of states in which they have a presence
substantial enough to require remittance of taxes. For example, unlike
Amazon which has no retail outlets,
Barnes and Noble has stores in 49
states. To get around the disadvantage
of needing to charge sales tax to nearly
every purchaser, Barnes and Noble
created barnesandnoble.com as a
separate company operated by Barnes
and Noble. In other ways, the companies
are not distinct entities, many of their
officers are the same, and the website
provides information on the stores.

The company decided to make it official
policy that the stores not accept returns on web purchases so that the
web company’s assertions of lack of
nexus would not be challenged.
Finally, the current situation is unpalatable because it makes the numerous
Internet shoppers who do not remit
sales taxes unwitting tax cheats.
Those who support the continuation
of the Internet as a sales tax haven
have tended to rely on both theoretical
and practical arguments. The theoretical position holds that an “infant
industry” should be given some
(financial) room to develop. This
view, espoused by Steve Forbes,10 only
holds if the Internet’s growth would be
substantially hampered if taxes were
applied to online sales. This is unlikely.
The practical argument against taxation is the same as that made by the
Supreme Court: Internet commerce
on taxable items could be dampened
if Internet firms were truly required to
submit use taxes to the 45 states with
use taxes and the thousands of localities
in the 27 states where local rates also
apply to use taxes. This is especially true
because these numerous jurisdictions
also have different tax bases and different registration requirements.
Elements of a solution
In the Internet Tax Freedom Act
(ITFA) of 1998, Congress created the
Advisory Commission on Electronic
Commerce (ACEC) to consider the
future of Internet taxation. Although
the ACEC was unable to generate
the two-thirds majority needed to
submit an official finding to Congress,
the proposals submitted by the commission’s three caucuses—business, antitax, and government—helped to clarify
the debate. Below, I detail the elements
of a solution, relying in part on the
proposals of the ACEC caucuses.
Simplification
The first step toward collecting tax
on Internet sales is to create a simplified mechanism for collecting and
remitting sales tax that is sponsored
and paid for by the states. Interestingly,

all three ACEC caucuses suggested
some form of sales tax simplification. Whether such a streamlined
collection requires dramatic sales
tax simplification or only sophisticated software provided to vendors or credit card companies is
an open question. The main concern is that taxation should be
easy to implement and not prohibitively costly to the vendors.
Equity and universality
The same product should be taxed
equally when purchased by Internet,
mail order, or in a retail store to
avoid distorting the decisions of
consumers and firms. In addition,
the submission of taxes should be
mandatory rather than voluntary.
(The government caucus proposed
experimenting with voluntary
agreements with retailers.) Such
universality would most likely require congressional action.
Timeliness
A program should be put in place
as quickly as possible. The business
caucus of the ACEC recommended
extending the tax moratorium in
the ITFA for an additional five years,
a plan endorsed 352-75 by the U.S.
House of Representatives. However,
the sooner taxes are put into place,
the sooner the distortion to firm
location and structure decisions will
end. These decisions may be difficult
to change once they are made. In
addition, as consumers grow accustomed to sales-tax-free Internet
shopping, taxes will become more
difficult to implement.
Clarity
Numerous nexus-related lawsuits
have arisen in order to determine
whether retailers are required to
remit taxes. These lawsuits are costly
to governments and businesses. In
order to avoid additional lawsuits,
any restrictions on sales taxation
should be as explicit as possible.
The business caucus proposed a
permanent exemption from sales
tax for “digitized goods and their
non-digitized counterparts.” This
exemption is troubling because the

definition of non-digitized counterparts could be subject to a wide variety of interpretations.
Revenue neutrality
The business caucus plan also recommends that methods be developed to
maintain revenue neutrality once remote
sales enter into the tax base. This is
not an essential feature of a solution
to the Internet tax situation. However,
a revenue neutral solution would attract
a broader base of support.

Conclusion
On May 10, 2000, the U.S. House voted
to extend the Internet tax ban for
another five years. The Senate has not
yet voted upon the measure. As the
debate intensifies, three important
things could occur. First, the states
could work toward developing a more
streamlined tax system. A system that
made it possible for remote sellers to
deal with only one agency or tax code
would greatly reduce the burden on
remote sellers. Second, the states could
cultivate allies within the business community to put additional pressure on
Congress. Traditional brick and mortar
retailers have yet to add their substantial
political muscle to the debate. The fact

that such a small percentage of retail
sales occur on the Internet highlights
the fact that corporations that need
to remit taxes and are disadvantaged
still far outnumber those with only
an online presence. With easier filing
requirements, the large e-commerce
corporations may also begin to support
applying the sales tax to remote purchases. As these companies get larger,
they will generate nexus in more states
and will be at a disadvantage relative to
smaller suppliers. They may also wish
to avoid the constant threat of nexusrelated lawsuits. Third, as states increase efforts to enforce use tax
collections, voters may become more
uncomfortable with the use tax situation and prefer to deal with firms that
directly remit use tax payments. These
forces may lead Congress to enact a
permanent solution to the remote
sales tax issue.

In Quill, the court reversed its earlier decision that the taxation of remote sales violated
the due process clause of the Constitution, as
well as the commerce clause. This is important
because Congress could not authorize states to
collect a tax that violated due process, while it
has explicit constitutional authority to regulate
interstate commerce.
