LO 12.1:
Identify the organizational
structure of the IRS.
The national office is the headquarters of the commissioner of internal revenue. The com-
missioner of internal revenue is appointed by the president of the United States with the
advice and consent of the Senate.
The IRS maintains ten service centers where the IRS computers process the information from
tax documents such as tax returns, payroll tax forms, Form 1099s, and withholding forms.
The IRS maintains a national computer center in Martinsburg, West Virginia, where informa-
tion from various service centers is matched with records from other service centers.
The IRS has the authority to examine a taxpayer’s books and records to determine the cor-
rect amount of tax due, and the IRS also has the right to summon taxpayers to appear
before the IRS and produce necessary accounting records.
LO 12.2:
Understand the IRS audit process.
A primary function of the IRS is to audit taxpayers’ tax returns.
The office audit is conducted in an IRS office and is typically used for individual taxpayers
with little or no business activities.
In a field audit, the IRS agent reviews a taxpayer’s books and records at the taxpayer’s
place of business or at the office of the taxpayer’s accountant.
The IRS uses a computerized statistical sampling technique called the Discriminant Function
(DIF) System to select tax returns for most audits.
Under the DIF system, the IRS uses mathematical formulas to assign a DIF score to each return,
which represents the potential for discovery of improper treatment of items on the tax return.
The IRS also selects returns for audit using information from other sources such as inform-
ants, other governmental agencies, news items, and associated tax returns.
If an audit results in a disagreement between the agent and the taxpayer, the appeals procedure
begins with the IRS inviting the taxpayer to an informal conference with an appellate agent.
LO 12.3:
Define the common penalties for
taxpayers and tax preparers and
be able to apply them to specific
situations.
Taxpayers are charged interest on underpayments of taxes, and, in some cases, the IRS
pays interest to taxpayers when they overpay their taxes.
The interest rate applicable to underpayments and overpayments of taxes is adjusted each
quarter and is equal to the federal short-term rate plus three percentage points.
The failure to file is subject to a penalty equal to 5 percent of the tax due with the return,
for every month or portion of a month the return is late (to a maximum of 25%).
The penalty for failure to pay is ½ of 1 percent of the amount of taxes due for every
month or portion of a month that the payment is late (to a maximum of 25%).
The accuracy-related penalty is 20 percent of the applicable underpayment due to (1) negligence
or disregard of rules or regulations, (2) a substantial understatement of income tax, or (3) a
substantial valuation overstatement, as well as certain other understatements of income tax.
When a taxpayer files a fraudulent tax return, there is a fraud penalty equal to 75 percent
of the amount of underpayment of taxes attributable to fraud.
The tax law contains many other penalties applicable to taxpayers: A civil penalty of $500
and a criminal penalty of $1,000 are imposed for filing false withholding information, and
there is a $500 penalty for filing a ‘‘frivolous’’ tax return (or document) as a tax protest.
LO 12.4:
Apply the general rule for the stat-
ute of limitations on tax returns
and the important exceptions to
the general rule.
In general, the statute of limitations for a tax return runs for 3 years from the date the tax
return was filed or the return due date, whichever is later.
If a fraudulent tax return is filed or no return is filed, there is no statute of limitations.
If a taxpayer omits an amount of gross income in excess of 25 percent of the gross income
shown on the return, then the statute of limitations is increased to 6 years.
The statute of limitations for the deduction of a bad debt or worthless security is 7 years
(all other items on the tax return would normally be considered closed after 3 years).
The statute of limitations may be extended by mutual consent of the IRS and the taxpayer.
