                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.469-4  Definition of activity.

    (a) Scope and purpose. This section sets forth the rules for 
grouping a taxpayer's trade or business activities and rental activities 
for purposes of applying the passive activity loss and credit limitation 
rules of section 469. A taxpayer's activities include those conducted 
through C corporations that are subject to section 469, S corporations, 
and partnerships.
    (b) Definitions. The following definitions apply for purposes of 
this section--
    (1) Trade or business activities. Trade or business activities are 
activities, other than rental activities or activities that are treated 
under Sec. 1.469-1T(e)(3)(vi)(B) as incidental to an activity of 
holding property for investment, that--
    (i) Involve the conduct of a trade or business (within the meaning 
of section 162);
    (ii) Are conducted in anticipation of the commencement of a trade or 
business; or
    (iii) Involve research or experimental expenditures that are 
deductible under section 174 (or would be deductible if the taxpayer 
adopted the method described in section 174(a)).
    (2) Rental activities. Rental activities are activities that 
constitute rental activities within the meaning of Sec. 1.469-1T(e)(3).
    (c) General rules for grouping activities--(1) Appropriate economic 
unit. One or more trade or business activities or rental activities may 
be treated as a single activity if the activities constitute an 
appropriate economic unit for the measurement of gain or loss for 
purposes of section 469.
    (2) Facts and circumstances test. Except as otherwise provided in 
this section, whether activities constitute an appropriate economic unit 
and, therefore, may be treated as a single activity depends upon all the 
relevant facts and circumstances. A taxpayer may use any reasonable 
method of applying the relevant facts and circumstances in grouping 
activities. The factors listed below, not all of which are necessary for 
a taxpayer to treat more than one activity as a single activity, are 
given the greatest weight in determining whether activities constitute 
an appropriate economic unit for the measurement of gain or loss for 
purposes of section 469--
    (i) Similarities and differences in types of trades or businesses;
    (ii) The extent of common control;
    (iii) The extent of common ownership;

[[Page 437]]

    (iv) Geographical location; and
    (v) Interdependencies between or among the activities (for example, 
the extent to which the activities purchase or sell goods between or 
among themselves, involve products or services that are normally 
provided together, have the same customers, have the same employees, or 
are accounted for with a single set of books and records).
    (3) Examples. The following examples illustrate the application of 
this paragraph (c).

    Example 1. Taxpayer C has a significant ownership interest in a 
bakery and a movie theater at a shopping mall in Baltimore and in a 
bakery and a movie theater in Philadelphia. In this case, after taking 
into account all the relevant facts and circumstances, there may be more 
than one reasonable method for grouping C's activities. For instance, 
depending on the relevant facts and circumstances, the following 
groupings may or may not be permissible: a single activity; a movie 
theater activity and a bakery activity; a Baltimore activity and a 
Philadelphia activity; or four separate activities. Moreover, once C 
groups these activities into appropriate economic units, paragraph (e) 
of this section requires C to continue using that grouping in subsequent 
taxable years unless a material change in the facts and circumstances 
makes it clearly inappropriate.
    Example 2. Taxpayer B, an individual, is a partner in a business 
that sells non-food items to grocery stores (partnership L). B also is a 
partner in a partnership that owns and operates a trucking business 
(partnership Q). The two partnerships are under common control. The 
predominant portion of Q's business is transporting goods for L, and Q 
is the only trucking business in which B is involved. Under this 
section, B appropriately treats L's wholesale activity and Q's trucking 
activity as a single activity.

    (d) Limitation on grouping certain activities. The grouping of 
activities under this section is subject to the following limitations:
    (1) Grouping rental activities with other trade or business 
activities--(i) Rule. A rental activity may not be grouped with a trade 
or business activity unless the activities being grouped together 
constitute an appropriate economic unit under paragraph (c) of this 
section and--
    (A) The rental activity is insubstantial in relation to the trade or 
business activity;
    (B) The trade or business activity is insubstantial in relation to 
the rental activity; or
    (C) Each owner of the trade or business activity has the same 
proportionate ownership interest in the rental activity, in which case 
the portion of the rental activity that involves the rental of items of 
property for use in the trade or business activity may be grouped with 
the trade or business activity.
    (ii) Examples. The following examples illustrate the application of 
paragraph (d)(1)(i) of this section:

    Example 1. (i) H and W are married and file a joint return. H is the 
sole shareholder of an S corporation that conducts a grocery store trade 
or business activity. W is the sole shareholder of an S corporation that 
owns and rents out a building. Part of the building is rented to H's 
grocery store trade or business activity (the grocery store rental). The 
grocery store rental and the grocery store trade or business are not 
insubstantial in relation to each other.
    (ii) Because they file a joint return, H and W are treated as one 
taxpayer for purposes of section 469. See Sec. 1.469-1T(j). Therefore, 
the sole owner of the trade or business activity (taxpayer H-W) is also 
the sole owner of the rental activity. Consequently, each owner of the 
trade or business activity has the same proportionate ownership interest 
in the rental activity. Accordingly, the grocery store rental and the 
grocery store trade or business activity may be grouped together (under 
paragraph (d)(1)(i) of this section) into a single trade or business 
activity, if the grouping is appropriate under paragraph (c) of this 
section.
    Example 2. Attorney D is a sole practitioner in town X. D also 
wholly owns residential real estate in town X that D rents to third 
parties. D's law practice is a trade or business activity within the 
meaning of paragraph (b)(1) of this section. The residential real estate 
is a rental activity within the meaning of Sec. 1.469-1T(e)(3) and is 
insubstantial in relation to D's law practice. Under the facts and 
circumstances, the law practice and the residential real estate do not 
constitute an appropriate economic unit under paragraph (c) of this 
section. Therefore, D may not treat the law practice and the residential 
real estate as a single activity.

    (2) Grouping real property rentals and personal property rentals 
prohibited. An activity involving the rental of real property and an 
activity involving the rental of personal property (other than personal 
property provided in connection with the real property or real

[[Page 438]]

property provided in connection with the personal property) may not be 
treated as a single activity.
    (3) Certain activities of limited partners and limited 
entrepreneurs--(i) In general. Except as provided in this paragraph, a 
taxpayer that owns an interest, as a limited partner or a limited 
entrepreneur (as defined in section 464(e)(2)), in an activity described 
in section 465(c)(1), may not group that activity with any other 
activity. A taxpayer that owns an interest as a limited partner or a 
limited entrepreneur in an activity described in the preceding sentence 
may group that activity with another activity in the same type of 
business if the grouping is appropriate under the provisions of 
paragraph (c) of this section.
    (ii) Example. The following example illustrates the application of 
this paragraph (d)(3):

    Example. (i) Taxpayer A, an individual, owns and operates a farm. A 
is also a member of M, a limited liability company that conducts a 
cattle-feeding business. A does not actively participate in the 
management of M (within the meaning of section 464(e)(2)(B)). In 
addition, A is a limited partner in N, a limited partnership engaged in 
oil and gas production.
    (ii) Because A does not actively participate in the management of M, 
A is a limited entrepreneur in M's activity. M's cattle-feeding business 
is described in section 465(c)(1)(B) (relating to farming) and may not 
be grouped with any other activity that does not involve farming. 
Moreover, A's farm may not be grouped with the cattle-feeding activity 
unless the grouping constitutes an appropriate economic unit for the 
measurement of gain or loss for purposes of section 469.
    (iii) Because A is a limited partner in N and N's activity is 
described in section 465(c)(1)(D) (relating to exploring for, or 
exploiting, oil and gas resources), A may not group N's oil and gas 
activity with any other activity that does not involve exploring for, or 
exploiting, oil and gas resources. Thus, N's activity may not be grouped 
with A's farm or with M's cattle-feeding business.

    (4) Other activities identified by the Commissioner. A taxpayer that 
owns an interest in an activity identified in guidance issued by the 
Commissioner as an activity covered by this paragraph (d)(4) may not 
group that activity with any other activity, except as provided in the 
guidance issued by the Commissioner.
    (5) Activities conducted through section 469 entities--(i) In 
general. A C corporation subject to section 469, an S corporation, or a 
partnership (a section 469 entity) must group its activities under the 
rules of this section. Once the section 469 entity groups its 
activities, a shareholder or partner may group those activities with 
each other, with activities conducted directly by the shareholder or 
partner, and with activities conducted through other section 469 
entities, in accordance with the rules of this section. A shareholder or 
partner may not treat activities grouped together by a section 469 
entity as separate activities.
    (ii) Cross reference. An activity that a taxpayer conducts through a 
C corporation subject to section 469 may be grouped with another 
activity of the taxpayer, but only for purposes of determining whether 
the taxpayer materially or significantly participates in the other 
activity. See Sec. 1.469-2T(c)(3)(i)(A) and (c)(4)(i) for the rules 
regarding dividends on C corporation stock and compensation paid for 
personal services.
    (e) Disclosure and consistency requirements--(1) Original groupings. 
Except as provided in paragraph (e)(2) of this section and Sec. 1.469-
11, once a taxpayer has grouped activities under this section, the 
taxpayer may not regroup those activities in subsequent taxable years. 
Taxpayers must comply with disclosure requirements that the Commissioner 
may prescribe with respect to both their original groupings and the 
addition and disposition of specific activities within those chosen 
groupings in subsequent taxable years.
    (2) Regroupings. If it is determined that a taxpayer's original 
grouping was clearly inappropriate or a material change in the facts and 
circumstances has occurred that makes the original grouping clearly 
inappropriate, the taxpayer must regroup the activities and must comply 
with disclosure requirements that the Commissioner may prescribe.
    (f) Grouping by Commissioner to prevent tax avoidance--(1) Rule. The 
Commissioner may regroup a taxpayer's activities if any of the 
activities resulting from the taxpayer's grouping is not an

[[Page 439]]

appropriate economic unit and a principal purpose of the taxpayer's 
grouping (or failure to regroup under paragraph (e) of this section) is 
to circumvent the underlying purposes of section 469.
    (2) Example. The following example illustrates the application of 
this paragraph (f):

    Example. (i) Taxpayers D, E, F, G, and H are doctors who operate 
separate medical practices. D invested in a tax shelter several years 
ago that generates passive losses and the other doctors intend to invest 
in real estate that will generate passive losses. The taxpayers form a 
partnership to engage in the trade or business of acquiring and 
operating X-ray equipment. In exchange for equipment contributed to the 
partnership, the taxpayers receive limited partnership interests. The 
partnership is managed by a general partner selected by the taxpayers; 
the taxpayers do not materially participate in its operations. 
Substantially all of the partnership's services are provided to the 
taxpayers or their patients, roughly in proportion to the doctors' 
interests in the partnership. Fees for the partnership's services are 
set at a level equal to the amounts that would be charged if the 
partnership were dealing with the taxpayers at arm's length and are 
expected to assure the partnership a profit. The taxpayers treat the 
partnership's services as a separate activity from their medical 
practices and offset the income generated by the partnership against 
their passive losses.
    (ii) For each of the taxpayers, the taxpayer's own medical practice 
and the services provided by the partnership constitute an appropriate 
economic unit, but the services provided by the partnership do not 
separately constitute an appropriate economic unit. Moreover, a 
principal purpose of treating the medical practices and the 
partnership's services as separate activities is to circumvent the 
underlying purposes of section 469. Accordingly, the Commissioner may 
require the taxpayers to treat their medical practices and their 
interests in the partnership as a single activity, regardless of whether 
the separate medical practices are conducted through C corporations 
subject to section 469, S corporations, partnerships, or sole 
proprietorships. The Commissioner may assert penalties under section 
6662 against the taxpayers in appropriate circumstances.

    (g) Treatment of partial dispositions. A taxpayer may, for the 
taxable year in which there is a disposition of substantially all of an 
activity, treat the part disposed of as a separate activity, but only if 
the taxpayer can establish with reasonable certainty--
    (1) The amount of deductions and credits allocable to that part of 
the activity for the taxable year under Sec. 1.469-1(f)(4) (relating to 
carryover of disallowed deductions and credits); and
    (2) The amount of gross income and of any other deductions and 
credits allocable to that part of the activity for the taxable year.
    (h) Rules for grouping rental real estate activities for taxpayers 
qualifying under section 469(c)(7). See Sec. 1.469-9 for rules for 
certain rental real estate activities.
