Sec. 301.6501(e)-1  Omission from return.

    (a) Income taxes--(1) General rule. (i) If the taxpayer omits from 
the gross income stated in the return of a tax imposed by subtitle A of 
the Code an amount properly includible therein which is in excess of 25 
percent of the gross income so stated, the tax may be assessed, or a 
proceeding in court for the collection of such tax may be begun without 
assessment, at any time within 6 years after the return was filed.
    (ii) For purposes of this subparagraph, the term ``gross income'', 
as it relates to a trade or business, means the total of the amounts 
received or accrued from the sale of goods or services, to the extent 
required to be shown on the return, without reduction for the cost of 
such sales or services. An item shall not be considered as omitted from 
gross income if information, sufficient to apprise the district director 
of the nature and amount of such item, is disclosed in the return or in 
any schedule or statement attached to the return.
    (2) Constructive dividends. If a taxpayer omits from gross income an 
amount properly includible therein under section 551(b) as his 
distributive share of the undistributed foreign personal holding company 
income, the tax may be assessed, or a proceeding in court for the 
collection of such tax may be begun without assessment, at any time 
within 6 years after the return was filed.
    (b) Estate and gift taxes. (1) If the taxpayer omits from the gross 
estate as stated in the estate tax return, or from the total amount of 
the gifts made during the period for which the gift tax return was filed 
(see Sec. 25.6019-1 of this chapter) as stated in such return, an item 
or items properly includible therein the amount of which is in excess of 
25 percent of the gross estate as stated in the return, or 25 percent of 
the total amount of the gifts as stated in the return, the tax may be 
assessed, or a proceeding in court for the collection thereof may be 
begun without assessment, at any time within 6 years after the return 
was filed.
    (2) For purposes of this paragraph, an item disclosed in the return 
or in any schedule or statement attached to the return in a manner 
sufficient to apprise the district director of the nature and amount 
thereof shall not be taken into account in determining items omitted 
from the gross estate or total gifts, as the case may be. Further,

[[Page 367]]

there shall not be taken into account in computing the 25 percent 
omission from the gross estate stated in the estate tax return or from 
the total gifts stated in the gift tax return, any increases in the 
valuation of assets disclosed on the return.
    (c) Excise taxes--(1) In general. If the taxpayer omits from a 
return of a tax imposed under a provision of subtitle D an amount 
properly includable thereon, which amount is in excess of 25 percent of 
the amount of tax reported thereon, the tax may be assessed or a 
proceeding in court for the collection thereof may be begun without 
assessment, at any time within 6 years after the return was filed. For 
special rules relating to chapter 41, 42, 43, and 44 taxes, see 
subparagraphs (2), (3), (4), and (5) of this paragraph.
    (2) Chapter 41 excise taxes. If an organization discloses an 
expenditure in its return (or in a schedule or statement attached 
thereto) in a manner sufficient to apprise the district director or 
director of a service center of the existing and nature of such 
expenditure, the three year limitation on assessment and collection 
described in section 6501(a) shall apply with respect to any tax under 
chapter 41 arising from such expenditure. If a taxpayer fails to so 
disclose an expenditure in its return (or in a schedule or statement 
attached thereto), the tax arising from the expenditure not so disclosed 
may be assessed, or a proceeding in court for the collection of such tax 
may be begun without assessment, at any time within 6 years after the 
return was filed.
    (3) Chapter 42 excise taxes. (i) If a private foundation omits from 
its annual return with respect to the tax imposed by section 4940 an 
amount of tax properly includible therein which is in excess of 25 
percent of the amount of tax imposed by section 4940 which is reported 
on the return, the tax may be assessed, or a proceeding in court for the 
collection of such tax may be begun without assessment, at any time 
within 6 years after the return was filed. If a private foundation 
discloses in its return (or in a schedule or statement attached thereto) 
the nature, source, and amount of any income giving rise to any omitted 
tax, the tax arising from such income shall be counted as reported on 
the return in computing whether the foundation has omitted more than 25 
percent of the tax reported on its return.
    (ii) If a private foundation trust, or other organization (as the 
case may be) discloses an item in its return (or in a schedule or 
statement attached thereto) in a manner sufficient to apprise the 
district director or director of a service center of the existence and 
nature of such item, the three year limitation on assessment and 
collection described in section 6501(a) shall apply with respect to any 
tax imposed under sections 4941(a), 4942(a), 4943(a), 4944(a), 4945(a), 
4951(a), 4952(a), 4953, and 4958 arising from any transaction disclosed 
by such item. If a private foundation trust, or other organization (as 
the case may be) fails to so disclose an item in its return (or in a 
schedule or statement attached thereto), the tax arising from any 
transaction not so disclosed may be assessed or a proceeding in court 
for the collection of such tax may be begun without assessment, at any 
time within 6 years after the return was filed.
    (4) Chapter 43 excise taxes. If a taxpayer discloses an item in its 
return (or in a schedule or statement attached thereto) in a manner 
sufficient to apprise the district director or director of a service 
center of the existence and nature of such item, the three year 
limitation on assessment and collection described in section 6501(a) 
shall apply with respect to any tax imposed under sections 4971(a), 
4972, 4973, 4974, and 4975(a) arising from any transaction disclosed by 
such item. If a taxpayer fails to so disclose an item in its return (or 
in a schedule or statement attached thereto), the tax arising from any 
transaction not so disclosed may be assessed, or a proceeding in court 
for the collection of such tax may be begun without assessment, at any 
time within 6 years after the return was filed. The applicable return 
for the tax under sections 4971, 4972, 4973 and 4974 is the return 
designated by the Commissioner for reporting the respective tax. The 
applicable return for the tax under section 4975 is the return filed by 
the plan used to report the act giving rise to the tax.

    (5) Chapter 44 excise taxes. If a real estate investment trust omits 
from its annual return with respect to the tax imposed by section 4981 
an amount of tax properly includible therein which is in excess of 25 
percent of the amount of tax imposed by section 4981 which is reported 
on the return, the tax may be assessed, or a proceeding in court for the 
collection of such tax may be begun without assessment, at any time 
within 6 years after the return was filed. If a real estate investment 
trust discloses in its return (or in a schedule or statement attached 
thereto) the nature, source, and amount of any income giving rise to any 
omitted tax, the tax arising from such income shall be counted as 
reported on the return in computing whether the trust has omitted more 
than 25 percent of the tax reported on its return.
    (d) Exception. The provisions of this section do not limit the 
application of section 6501(c).
