Greater of $1,000 or 50 percent of the income derived (or to be derived) by the tax
return preparer for an undisclosed unrealistic position on a return which does not
meet a ‘‘substantial authority’’ standard, and which the preparer knew or reasonably
should have known about.
Greater of $5,000 or 50 percent of the income derived (or to be derived) by the tax
return preparer for each return in which the preparer willfully attempts to understate the
amount of the taxpayer’s tax liability, or each return in which an understatement is due
to the preparer’s reckless or intentional disregard of rules or regulations, reduced by the
amount of the $1,000 (or 50 percent) penalty for unrealistic positions (discussed above).
$1,000 ($10,000 for corporate returns) for each return or document filed in aiding
or abetting a taxpayer in understating a tax liability.
For each separate activity (sale of an interest, organization of an entity, etc.), the
lesser of $1,000 or 100 percent of the gross income derived by the promoter from
promoting an ‘‘abusive tax shelter.’’
Burden of Proof
In most litigation, the party initiating the case has the burden of convincing the court that
he or she is correct with respect to the issue. Historically, how ever, in most civil tax cases,
the Internal Revenue Code placed the burden of proof on the taxpayer, whether or not he
or she initiated the case, except in cases involving such items as hobby losses , fraud with
intent to evade tax, and the accumulated earnings tax.
In the IRS Restructuring and Reform Act of 1998, the tax law was changed to shift the
burden of proof to the IRS in many situations. The IRS now has the burden of proof in any
court proceeding on an income, gift, estate, or generation-skipping tax liability with
respect to factual issues, provided the taxpayer (1) introduces credible evidence of the fac-
tual issue, (2) maintains records and substantiates items as presently required under the
Code and Regulations, and (3) cooperates with reasonable IRS requests for meetings, inter-
views, witnesse s, information, and documents. For corporations, trusts, and partnerships
with net worth exceeding $7 million, the burden of proof remains on the taxpayer. The
new rules apply only to those IRS-taxpayer disputes arising in connection with audits
started after the 1998 Act was signed into law.
The burden of proof also automatically shifts to the IRS in two situations:
if the IRS uses statistics to reconstruct an individual’s income, or
if the court proceeding against an individual taxpayer involves a penalty or addition to tax.
Tax Confidentiality Privilege
The 1998 Act also extended the existing attorney-client privilege of con fidentiality in tax
matters to nonattorneys authorized t o practice before the IRS (e.g., CPAs and enrolled
agents). The nonattorney-client privilege may be asserted only in a noncriminal tax pro-
ceeding before the IRS or federal courts . Also, the nonattorney-client privilege does not
extend to written communications between a tax practitioner and a corporation in connec-
tion with the promotion of any tax shelter.
CPAs and enrolled agents need to understand the rules regarding tax confidentiality as
they have been applied to lawyers to be aware of the tax privilege limits. For example, tax
privileged communication usually does not apply to the preparation of tax returns, the giv-
ing of accounting or business advice, or to tax accrual workpapers. Also, unlike the general
attorney-client privilege, the nonattorney-client privilege does not automatically apply to
state tax situations.
