                               Assessment
 
Sec. 301.6213-1  Restrictions applicable to deficiencies; petition to 
Tax Court.

    (a) Time for filing petition and restrictions on assessment--(1) 
Time for filing petition. Within 90 days after notice of the deficiency 
is mailed (or within 150 days after mailing in the case of such notice 
addressed to a person outside

[[Page 160]]

the States of the Union and the District of Columbia), as provided in 
section 6212, a petition may be filed with the Tax Court of the United 
States for a redetermination of the deficiency. In determining such 90-
day or 150-day period, Saturday, Sunday, or a legal holiday in the 
District of Columbia is not counted as the 90th or 150th day. In 
determining the time for filing a petition with the Tax Court in the 
case of a notice of deficiency mailed to a resident of Alaska prior to 
12:01 p.m., e.s.t., January 3, 1959, and in the case of a notice of 
deficiency mailed to a resident of Hawaii prior to 4 p.m., e.d.s.t., 
August 21, 1959, the term ``States of the Union'' does not include 
Alaska or Hawaii, respectively, and the 150-day period applies. In 
determining the time within which a petition to the Tax Court may be 
filed in the case of a notice of deficiency mailed to a resident of 
Alaska after 12:01 p.m., e.s.t., January 3, 1959, and in the case of a 
notice of deficiency mailed to a resident of Hawaii after 4 p.m., 
e.d.s.t., August 21, 1959, the term ``States of the Union'' includes 
Alaska and Hawaii, respectively, and the 90-day period applies.
    (2) Restrictions on assessment. Except as otherwise provided by this 
section, by sections 6851, 6852, and 6861(a) (relating to termination 
and jeopardy assessments), by section 6871(a) (relating to immediate 
assessment of claims for income, estate, and gift taxes in bankruptcy 
and receivership cases), or by section 7485 (in case taxpayer petitions 
for a review of a Tax Court decision without filing bond), no assessment 
of a deficiency in respect of a tax imposed by subtitle A or B or 
chapter 41, 42, 43, or 44 of the Code and no levy or proceeding in court 
for its collection shall be made until notice of deficiency has been 
mailed to the taxpayer, nor until the expiration of the 90-day or 150-
day period within which a petition may be filed with the Tax Court, nor, 
if a petition has been filed with the Tax Court, until the decision of 
the Tax Court has become final. As to the date on which a decision of 
the Tax court becomes final, see section 7481. Notwithstanding the 
provisions of section 7421(a), the making of an assessment or the 
beginning of a proceeding or levy which is forbidden by this paragraph 
may be enjoined by a proceeding in the proper court. In any case where 
the running of the time prescribed for filing a petition in the Tax 
Court with respect to a tax imposed by chapter 42 or 43 is suspended 
under section 6213(e), no assessment of a deficiency in respect of such 
tax shall be made until expiration of the entire period for filing the 
petition.
    (b) Exceptions to restrictions on assessment of deficiencies--(1) 
Mathematical errors. If a taxpayer is notified of an additional amount 
of tax due on account of a mathematical error appearing upon the return, 
such notice is not deemed a notice of deficiency, and the taxpayer has 
no right to file a petition with the Tax Court upon the basis of such 
notice, nor is the assessment of such additional amount prohibited by 
section 6213(a).
    (2) Tentative carryback adjustments. (i) If the district director or 
the director of the regional service center determines that any amount 
applied, credited, or refunded under section 6411(b) with respect to an 
application for a tentative carryback adjustment is in excess of the 
overassessment properly attributable to the carryback upon which such 
application was based, the district director or the director of the 
regional service center may assess the amount of the excess as a 
deficiency as if such deficiency were due to a mathematical error 
appearing on the return. That is, the district director or the director 
of the regional service center may assess an amount equal to the excess, 
and such amount may be collected, without regard to the restrictions on 
assessment and collection imposed by section 6213(a). Thus, the district 
director or the director of the regional service center may assess such 
amount without regard to whether the taxpayer has been mailed a prior 
notice of deficiency. Either before or after assessing such an amount, 
the district director or the director of the regional service center 
will notify the taxpayer that such assessment has been or will be made. 
Such notice will not constitute a notice of deficiency, and the taxpayer 
may not file a petition with the Tax Court of the United States based on 
such notice. However, the taxpayer, within the applicable period of 
limitation, may file a regular claim for

[[Page 161]]

credit or refund based on the carryback, if he has not already filed 
such a claim, and may maintain a suit based on such claim if it is 
disallowed or if it is not acted upon by the Internal Revenue Service 
within 6 months from the date the claim was filed.
    (ii) The method provided in subdivision (i) of this subparagraph to 
recover any amount applied, credited, or refunded in respect of an 
application for a tentative carryback adjustment which should not have 
been so applied, credited, or refunded is not an exclusive method. Two 
other methods are available to recover such amount: (a) By way of a 
deficiency notice under section 6212; or (b) by a suit to recover an 
erroneous refund under section 7405. Any one or more of the three 
available methods may be used to recover any amount which was improperly 
applied, credited, or refunded in respect of an application for a 
tentative carryback adjustment.
    (3) Assessment of amount paid. Any payment made after the mailing of 
a notice of deficiency which is made by the taxpayer as a payment with 
respect to the proposed deficiency may be assessed without regard to the 
restrictions on assessment and collection imposed by section 6213(a) 
even though the taxpayer has not filed a waiver of restrictions on 
assessment as provided in section 6213(d). A payment of all or part of 
the deficiency asserted in the notice together with the assessment of 
the amount so paid will not affect the jurisdiction of the Tax Court. If 
any payment is made before the mailing of a notice of deficiency, the 
district director or the director of the regional service center is not 
prohibited by section 6213(a) from assessing such amount, and such 
amount may be assessed if such action is deemed to be proper. If such 
amount is assessed, the assessment is taken into account in determining 
whether or not there is a deficiency for which a notice of deficiency 
must be issued. Thus, if such a payment satisfies the taxpayer's tax 
liability, no notice of deficiency will be mailed and the Tax Court will 
have no jurisdiction over the matter. In any case in which there is a 
controversy as to the correct amount of the tax liability, the 
assessment of any amount pursuant to the provisions of section 
6213(b)(3) shall in no way be considered to be the acceptance of an 
offer by the taxpayer to settle such controversy.
    (4) Jeopardy. If the district director believes that the assessment 
or collection of a deficiency will be jeopardized by delay, such 
deficiency shall be assessed immediately, as provided in section 
6861(a).
    (c) Failure to file petition. If no petition is filed with the Tax 
Court within the period prescribed in section 6213(a), the district 
director or the director of the regional service center shall assess the 
amount determined as the deficiency and of which the taxpayer was 
notified by registered or certified mail and the taxpayer shall pay the 
same upon notice and demand therefor. In such case the district director 
will not be precluded from determining a further deficiency and 
notifying the taxpayer thereof by registered or certified mail. If a 
petition is filed with the Tax Court the taxpayer should notify the 
district director who issued the notice of deficiency that the petition 
has been filed in order to prevent an assessment of the amount 
determined to be the deficiency.
    (d) Waiver of restrictions. The taxpayer may at any time by a signed 
notice in writing filed with the district director waive the 
restrictions on the assessment and collection of the whole or any part 
of the deficiency. The notice must in all cases be filed with the 
district director or other authorized official under whose jurisdiction 
the audit or other consideration of the return in question is being 
conducted. The filing of such notice with the Tax Court does not 
constitute filing with the district director within the meaning of the 
Code. After such waiver has been acted upon by the district director and 
the assessment has been made in accordance with its terms, the waiver 
cannot be withdrawn.
    (e) Suspension of filing period for certain chapter 42 and chapter 
43 taxes. The period prescribed by section 6213(a) for filing a petition 
in the Tax Court with respect to the taxes imposed by section 4941,4942, 
4943, 4944, 4945, 4951, 4952, 4955, 4958, 4971, or 4975, shall be 
suspended for

[[Page 162]]

any other period which the Commissioner has allowed for making 
correction under Sec. 53.4963-1(e)(3). Where the time for filing a 
petition with the Tax Court has been suspended under the authority of 
this paragraph (e), the extension shall not be reduced as a result of 
the correction being made prior to expiration of the period allowed for 
making correction.
