MOST RECENT DEVELOPMENTS
On December 7, 2000, a coalition of 19 tax reform organizations (both business and
civil)  called  on  the  U.S.  Congress  and  the  incoming  Administration  to  adopt  a  set  of
principles  that  would guide the debate over fundamental tax reform.  These principles
included a single low tax rate and the elimination of the bias against savings and investment.
BACKGROUND AND ANALYSIS
       Proposals to replace all or part of the income tax and proposals for national health care
have sparked congressional interest in possible sources of additional revenue.  A value-added
tax (VAT) or a national sales tax (NST) have been frequently discussed as possible new tax
services.  Both the VAT and the NST are taxes on the consumption of goods and services and
are conceptually similar.  Yet, these taxes also have significant differences.  This issue brief
discusses some of the potential policy implications associated with these differences.
Concept of a Value-Added Tax
The value added of a firm is the difference between a firm’s sales and a firm’s purchases
from all other firms.  In other words, a firm’s value added is simply the amount of value that
a firm contributes to a good or service by applying its factors of production (land, labor,
capital, and entrepreneurial ability).  A value-added tax would be a tax, levied at each stage
of production, on a firm’s net value added.  The credit method is usually used to collect the
VAT.  Under the credit method, a firm would calculate the VAT on its sales.  Next, a firm
would compute its VAT liability by subtracting the VAT paid on its inputs from the VAT on
its  sales, and would then remit the difference to the federal government to cover its tax
liability.
There are three types of VATs which differ in their tax treatment of purchases of capital
inputs (plant and equipment).  The consumption-type VAT treats capital purchases the same
way as the purchase of any other input, i.e., it is equivalent to expensing.  The other two types
of VATs are the income VAT and the gross product VAT.  Under the income VAT, the VAT
paid on the purchases of capital inputs is amortized (credit against the firm’s VAT liability)
over the expected lives of the capital inputs.  Under the gross product VAT, no deduction for
the VAT on purchases of capital inputs is allowed against the firm’s VAT liability.  The
consumption VAT is the only type of VAT that is used in developed nations and has been
proposed for the United States; consequently, the consumption VAT is contrasted with the
NST in this issue brief.
A National Sales Tax
A national sales tax (NST) would be a federal consumption tax collected only at the
retail level by vendors.  The NST would equal a set percentage of the retail price of taxable
goods and services.  Retail vendors would collect the NST and remit tax revenue to the
federal government.
IB92069

The retail price of a good or service equals the sum of value added at all stages of
production.  Consequently, a value-added tax and a national sales tax with the same tax rate
and  tax  base would yield the same amount of revenue.  The operating assumption of
policymakers and economists is that both taxes are fully shifted forward onto consumers; that
is,  the  price  to  the  consumer  increases  by  the  (full)  amount  of the tax.  For FY2000, a
broad-based VAT would have raised net revenue of approximately $37.8 billion for each 1%
levied.
Policy Implications
The  operating  differences  between  a  VAT  and  a  NST  have many important policy
implications, including the following eight factors:  administrative cost, joint tax collections,
avoiding double taxation of intermediate goods and services, enforcement, broadness of tax
base, maximum tax rate, time required to implement, and visibility.
Administrative Costs
Under a VAT, all firms would have to report tax information and collect taxes.  Under
a  NST,  firms  without  retail sales would not report or collect taxes.  But the substantial
majority of all firms would collect the NST since they have some retail sales.  Under a VAT
with a credit method of collection, each firm must keep invoices on all sales and purchases
from other firms, and these invoices would be subject to audit by tax authorities.  Hence, the
value-added tax would require more information to be reported and audited than a national
sales tax, and, consequently, a VAT could be expected to be more expensive to administer
than a NST.
Joint Tax Collection
Since 45 states and the District of Columbia have general sales taxes, an opportunity
exists for a NST to be collected jointly with state sales taxes.  A federal VAT could not be
jointly collected with state sales taxes.  States could convert their sales taxes to a VAT with
the federal tax base, but this is unlikely since it would require that the states establish an
entirely new tax system.  Consequently, no administrative costs saving would be expected
from a VAT; therefore, the collection costs of a VAT can be expected to be higher than a
NST.
Avoiding Double Taxation of Intermediate Goods and Services
Double taxation occurs if an input is taxed at the time of purchase and then a tax is
levied  on the same input again when it becomes part of the output of the firm.  A
consumption VAT, with the credit method of tax computation, easily excludes inputs from
taxation.  The exclusion of inputs from a NST would be more difficult.  Usually, firms buying
inputs  would  have  to  provide  sellers  with  exemption  certificates  before making their
purchases.  At the state level, procedures to exempt input purchases from state retail sales
taxes have worked imperfectly.  It is therefore reasonable to expect that excluding inputs from
taxation would be more difficult with a NST than with a VAT.

Enforcement
With a VAT, a firm would have a financial interest in ensuring that amounts of VAT paid
on  input purchases are accurately reported on its purchase invoices since the firm could
receive  credits  against  its  VAT  liability.  In addition, the VAT would provide the tax
authorities with an opportunity to cross-check the amount of VAT collected because data are
gathered from producers at different stages of production.  Some enforcement problems do
exist with a VAT.  For example, firms at different stages of production could collude to falsify
invoices.  But the NST lacks both the self-enforcing procedure and the cross-checking
opportunity of the VAT.  Hence, better compliance is expected from a VAT than with a NST.
Broadness of Tax Base
Because of the potential for better enforcement of a VAT, it may be possible to levy a
VAT on more goods and services than a NST.  This view is supported by the fact that VATs
of European nations, on the average, are levied on more goods and services than most state
sales taxes in the United States.
Maximum Tax Rate
Both the self-enforcing procedure and the cross-checking opportunity of a VAT would
increase the probability of a tax evader being apprehended.  Thus, for a given tax rate, a VAT
is expected to have better voluntary compliance than a NST.  In general, as a tax rate rises,
the  financial gains from tax evasion increase relative to the punishment if apprehended.
Consequently, it is expected that as a consumption tax rate is increased, the level of tax
evasion would rise.  Since voluntary compliance with a VAT is expected to be better than
with a NST, the tax rate for a VAT may be raised to a higher level than for a NST before a
problem with tax evasion occurs.
Time Required to Implement
The  VAT  would  take  more  time  to  implement than a NST.  The VAT is more
complicated and would cover more firms than a NST.  Also, business executives are not
familiar with this form of taxation, so the U.S. government would have to conduct an
educational campaign.
Visibility
The  value-added  tax  may  be  less  visible  to  consumers  than  a  national  sales  tax.
Policymakers and economists assume that 100% of both the VAT and the NST are passed
onto consumers.  But the perceptions of many consumers may be different about a VAT.
Many consumers may believe that a VAT tax would at least partially fall on firms because the
VAT is collected at each stage of production.  Since the NST is levied only at the retail level,
consumers  may  more  readily  believe  that  they  would  pay  the  entire  tax.  Furthermore,
policymakers have the option as to whether or not the amount of a VAT should be stated on
retail sales receipts.  The amount of a NST would be explicitly stated on sales receipts.

The  lower visibility of the VAT relative to the NST may be either desirable or
undesirable depending on one’s political ideology.  It can be argued that taxes should be
visible  so  that  the  costs  of  taxation  may  be  compared with the benefits of government
spending.  Conversely, it can be argued that people generally do not like the idea of paying
taxes; consequently, to finance public sector responsibilities, it is better to have taxes seem
as painless as possible.
