or policy; and (4) does the credit or policy add unnecessary complexity in the application,
administration and approval process for the corporation business tax. The committee

include the names or addresses of any taxpayers, but may include, for each recipient of
a tax credit, or business implementing a change in tax policy, a description of the business
activities, the amount of income apportioned to this state and the taxes paid on such
income, the exemption or credit taken and the amount of such exemption or credit, and
such other information as may be available to the Department of Revenue Services and

Sec. 12-233. Examination of returns by commissioner. Deadlines for mailing
deficiency assessments. Penalties for deficiencies. Payment by taxpayer. (a)(1) The
commissioner shall examine the tax return filed under this chapter by a taxpayer and
may make such further audit or investigation as the commissioner deems necessary,
and if the commissioner determines that there is a deficiency with respect to the payment
of any tax due under this chapter, the commissioner shall notify the taxpayer thereof.
Except as otherwise provided in this section, the commissioner shall (A) in the case of
a return on which an operating loss is not reported, not later than three years after the
due date for the filing of such return or not later than three years after the date on which
such return was received by such commissioner, whichever period expires later, or (B)
in the case of a return on which an operating loss is reported, not later than three years
after the due date or the date of receipt by the commissioner, whichever period expires
later, of the return on which a carry-over of such loss is fully utilized or deemed fully
utilized because such loss is not available for deduction in any subsequent income year,
examine it and, in case any error is disclosed by such examination, shall mail a notice
of deficiency assessment to the taxpayer. Where, within the sixty-day period ending on
the day on which the time prescribed in this section for mailing a notice of deficiency
assessment for any income year would otherwise expire, the commissioner receives a
written document signed by such taxpayer showing that such taxpayer owes an additional amount of tax for such income year, the commissioner then shall have up to
sixty days after the day such written document is received in which to mail a notice of
deficiency assessment.
(2) A notice of deficiency assessment may be mailed to the taxpayer at any time in
the case of (A) failure to file a return, including any amended return required pursuant
to section 12-226, or (B) a deficiency due to fraud or intent to evade the provisions of
this chapter or regulations promulgated thereunder.
(3) In the case of an omission from gross income of an amount properly includable
therein that is in excess of twenty-five per cent of the amount of gross income stated in
the return, a notice of deficiency assessment may be mailed to the taxpayer at any time
not later than six years after the return was filed. For purposes of this subdivision, there
shall not be taken into account any amount that is omitted from gross income stated in
the return if such amount is disclosed in the return or in a statement attached to the
return, in a manner adequate to apprise the commissioner of the nature and amount of
such item.
(4) In the case of a failure to disclose a listed transaction, as defined in Section
6707A of the Internal Revenue Code, on the taxpayer's federal income tax return, a
notice of deficiency assessment may be mailed to the taxpayer at any time not later than
six years after the return required under this chapter for the same income year was filed.
(b) (1) When it appears that any part of the deficiency for which a deficiency assessment is made is due to negligence or intentional disregard of the provisions of this part
or regulations promulgated thereunder, there shall be imposed a penalty equal to ten
per cent of the amount of such deficiency assessment, or fifty dollars, whichever is
greater. When it appears that any part of the deficiency for which a deficiency assessment
is made is due to fraud or intent to evade the provisions of this part or regulations
promulgated thereunder, there shall be imposed a penalty equal to twenty-five per cent
of the amount of such deficiency assessment. For audits of returns commencing on or
after January 1, 2006, when it appears that any part of the deficiency for which a deficiency assessment is made pursuant to section 12-233 is due to failure to disclose a
listed transaction, as defined in Section 6707A of the Internal Revenue Code of 1986,
or any subsequent corresponding internal revenue code of the United States, as from
time to time amended, on the taxpayer's federal tax return, there shall be imposed a
penalty equal to seventy-five per cent of the amount of such deficiency assessment.
(2) No taxpayer shall be subject to more than one penalty under this section in
relation to the same tax period.
(3) Any decision rendered by any federal court holding that a taxpayer has filed a
fraudulent return with the Director of Internal Revenue shall subject the taxpayer to the
penalty imposed by this section without the necessity of further proof thereof, except
when it can be shown that the return to the state so differed from the return to the federal
government as to afford a reasonable presumption that the attempt to defraud did not
extend to the return to the state.
(c) Not later than thirty days after the mailing of a notice of deficiency assessment,
the taxpayer shall pay to the commissioner, in cash or by check, draft or money order
drawn to the order of the Commissioner of Revenue Services, any additional amount
of tax shown to be due by such notice, or such taxpayer shall be paid by the State
Treasurer, upon order of the Comptroller, any amount shown to be due it by the corrected
return. The failure of the taxpayer to receive any timely mailed notice required by this
section shall not relieve such taxpayer of the obligation to pay the tax assessed under
the terms of this part or any interest or penalties thereon.
(d) When, before the expiration of the time prescribed in this section for the examination of the return or the assessment of the tax, both the commissioner and the taxpayer
have consented in writing to such examination or assessment after such time, the return
may be examined and the tax may be assessed at any time prior to the expiration of
the period agreed upon. The period so agreed upon may be extended by subsequent
agreements in writing made before the expiration of the period previously agreed upon.
The commissioner may also in such a case waive the statute of limitations against a
claim for refund by such taxpayer.
(e) For purposes of this section, a tax return filed under this chapter before the last
day prescribed by law or by any regulation adopted pursuant to this chapter for the filing
of such return, determined without regard to any extension of time for filing, shall be
deemed to be filed on such last day.
