Sec. 1.179-3  Carryover of disallowed deduction.

    (a) In general. Under section 179(b)(3)(B), a taxpayer may carry 
forward for an unlimited number of years the amount of any cost of 
section 179 property elected to be expensed in a taxable year but 
disallowed as a deduction in that taxable year because of the taxable 
income limitation of section 179(b)(3)(A) and Sec. 1.179-2(c) 
(``carryover of disallowed deduction''). This carryover of disallowed 
deduction may be deducted under section 179(a) and Sec. 1.179-1(a) in a 
future taxable year as provided in paragraph (b) of this section.

    (b) Deduction of carryover of disallowed deduction--(1) In general. 
The amount allowable as a deduction under section 179(a) and Sec. 
1.179-1(a) for any taxable year is increased by the lesser of--
    (i) The aggregate amount disallowed under section 179(b)(3)(A) and 
Sec. 1.179-2(c) for all prior taxable years (to the extent not 
previously allowed as a deduction by reason of this section); or
    (ii) The amount of any unused section 179 expense allowance for the 
taxable year (as described in paragraph (c) of this section).
    (2) Cross references. See paragraph (f) of this section for rules 
that apply when a taxpayer disposes of or otherwise transfers section 
179 property for which a carryover of disallowed deduction is 
outstanding. See paragraph (g) of this section for special rules that 
apply to partnerships and S corporations and paragraph (h) of this 
section for special rules that apply to partners and S corporation 
shareholders.
    (c) Unused section 179 expense allowance. The amount of any unused 
section 179 expense allowance for a taxable year equals the excess (if 
any) of--
    (1) The maximum cost of section 179 property that the taxpayer may 
deduct under section 179 and Sec. 1.179-1 for the taxable year after 
applying the limitations of section 179(b) and Sec. 1.179-2; over
    (2) The amount of section 179 property that the taxpayer actually 
elected to expense under section 179 and Sec. 1.179-1(a) for the 
taxable year.
    (d) Example. The following example illustrates the provisions of 
paragraphs (b) and (c) of this section.

    Example. A, a calendar-year taxpayer, has a $3,000 carryover of 
disallowed deduction for an item of section 179 property purchased and 
placed in service in 1991. In 1992, A purchases and places in service an 
item of section 179 property costing $25,000. A's 1992 taxable income 
from the active conduct of all A's trades or businesses is $100,000. A 
elects, under section 179(c) and Sec. 1.179-5, to expense $8,000 of the 
cost of the item of section 179 property purchased in 1992. Under 
paragraph (b) of this section, A may deduct $2,000 of A's carryover of 
disallowed deduction from 1991 (the lesser of A's total outstanding 
carryover of disallowed deductions ($3,000), or the amount of any unused 
section 179 expense allowance for 1992 ($10,000 limit less $8,000 
elected to be expensed, or $2,000)). For 1993, A has a $1,000 carryover 
of disallowed deduction for the item of section 179 property purchased 
and placed in service in 1991.

    (e) Recordkeeping requirement and ordering rule. The properties and 
the apportionment of cost that will be subject to a carryover of 
disallowed deduction are selected by the taxpayer in the year the 
properties are placed in service. This selection must be evidenced on 
the taxpayer's books and records and be applied consistently in 
subsequent years. If no selection is made, the total carryover of 
disallowed deduction is apportioned equally over the items of section 
179 property elected to be expensed for the taxable year. For this 
purpose, the taxpayer treats any section 179 expense amount allocated 
from a partnership (or an S corporation) for a taxable year as one item 
of section 179 property. If the taxpayer is allowed to deduct a portion 
of the total carryover of disallowed deduction under paragraph (b) of 
this section, the taxpayer must deduct the cost of section 179 property 
carried forward from the earliest taxable year.
    (f) Dispositions and other transfers of section 179 property--(1) In 
general. Upon a sale or other disposition of section 179 property, or a 
transfer of section 179 property in a transaction in which gain or loss 
is not recognized in whole or in part (including transfers at death), 
immediately before the transfer the adjusted basis of the section 179 
property is increased by the amount of any outstanding carryover of 
disallowed deduction with respect to the property. This carryover of 
disallowed deduction is not available as a deduction to the transferor 
or the transferee of the section 179 property.
    (2) Recapture under section 179(d)(10). Under Sec. 1.179-1(e), if a 
taxpayer's section 179 property is subject to recapture under section 
179(d)(10), the taxpayer must recapture the benefit derived from 
expensing the property. Upon recapture, any outstanding carryover of 
disallowed deduction with respect to the property is no longer available 
for expensing. In determining the amount subject to recapture under 
section 179(d)(10) and Sec. 1.179-1(e), any outstanding carryover of 
disallowed deduction with respect to that property is not treated as an 
amount expensed under section 179.

    (g) Special rules for partnerships and S corporations--(1) In 
general. Under section 179(d)(8) and Sec. 1.179-2(c), the taxable 
income limitation applies at the partnership level as well as at the 
partner level. Therefore, a partnership may have a carryover of 
disallowed deduction with respect to the cost of its section 179 
property. Similar rules apply to S corporations. This paragraph (g) 
provides special rules that apply when a partnership or an S corporation 
has a carryover of disallowed deduction.
    (2) Basis adjustment. Under Sec. 1.179-1(f)(2), the basis of a 
partnership's section 179 property must be reduced to reflect the amount 
of section 179 expense elected by the partnership. This reduction must 
be made for the taxable year for which the election is made even if the 
section 179 expense amount, or a portion thereof, must be carried 
forward by the partnership. Similar rules apply to S corporations.
    (3) Dispositions and other transfers of section 179 property by a 
partnership or an S corporation. The provisions of paragraph (f) of this 
section apply in determining the treatment of any outstanding carryover 
of disallowed deduction with respect to section 179 property disposed 
of, or transferred in a nonrecognition transaction, by a partnership or 
an S corporation.
    (4) Example. The following example illustrates the provisions of 
this paragraph (g).

    Example. ABC, a calendar-year partnership, owns and operates a 
restaurant business. During 1992, ABC purchases and places in service 
two items of section 179 property--a cash register costing $4,000 and 
office furniture costing $6,000. ABC elects to expense under section 
179(c) the full cost of the cash register and the office furniture. For 
1992, ABC has $6,000 of taxable income derived from the active conduct 
of its restaurant business. Therefore, ABC may deduct only $6,000 of 
section 179 expenses and must carry forward the remaining $4,000 of 
section 179 expenses at the partnership level. ABC must reduce the 
adjusted basis of the section 179 property by the full amount elected to 
be expensed. However, ABC may not allocate to its partners any portion 
of the carryover of disallowed deduction until ABC is able to deduct it 
under paragraph (b) of this section.

    (h) Special rules for partners and S corporation shareholders--(1) 
In general. Under section 179(d)(8) and Sec. 1.179-2(c), a partner may 
have a carryover of disallowed deduction with respect to the cost of 
section 179 property elected to be expensed by the partnership and 
allocated to the partner. A partner who is allocated section 179 
expenses from a partnership must reduce the basis of his or her 
partnership interest by the full amount allocated regardless of whether 
the partner may deduct for the taxable year the allocated section 179 
expenses or is required to carry forward all or a portion of the 
expenses. Similar rules apply to S corporation shareholders.
    (2) Dispositions and other transfers of a partner's interest in a 
partnership or a shareholder's interest in an S corporation. A partner 
who disposes of a partnership interest, or transfers a partnership 
interest in a transaction in which gain or loss is not recognized in 
whole or in part (including transfers of a partnership interest at 
death), may have an outstanding carryover of disallowed deduction of 
section 179 expenses allocated from the partnership. In such a case, 
immediately before the transfer the partner's basis in the partnership 
interest is increased by the amount of the partner's outstanding 
carryover of disallowed deduction with respect to the partnership 
interest. This carryover of disallowed deduction is not available as a 
deduction to the transferor or transferee partner of the section 179 
property. Similar rules apply to S corporation shareholders.
    (3) Examples. The following examples illustrate the provisions of 
this paragraph (h).

    Example 1. (i) G is a general partner in GD, a calendar-year 
partnership, and is engaged in the active conduct of GD's business. 
During 1991, GD purchases and places section 179 property in service and 
elects to expense a portion of the cost of the property under section 
179. GD allocates $2,500 of section 179 expenses and $15,000 of taxable 
income (determined without regard to the section 179 deduction) to G. 
The income was derived from the active conduct by GD of a trade or 
business.
    (ii) In addition to being a partner in GD, G conducts a business as 
a sole proprietor. During 1991, G purchases and places in service office 
equipment costing $25,000 and a computer costing $10,000 in connection 
with the sole proprietorship. G elects under section 179(c) and Sec. 
1.179-5 to expense $7,500 of the cost of the office equipment. G has a 
taxable

[[Page 229]]

loss (determined without regard to the section 179 deduction) derived 
from the active conduct of this business of $12,500.
    (iii) G has no other taxable income (or loss) derived from the 
active conduct of a trade or business during 1991. G's taxable income 
limitation for 1991 is $2,500 ($15,000 taxable income allocated from GD 
less $12,500 taxable loss from the sole proprietorship). Therefore, G 
may deduct during 1991 only $2,500 of the $10,000 of section 179 
expenses. G notes on the appropriate books and records that G expenses 
the $2,500 of section 179 expenses allocated from GD and carries forward 
the $7,500 of section 179 expenses with respect to the office equipment 
purchased by G's sole proprietorship.
    (iv) On January 1, 1992, G sells the office equipment G's sole 
proprietorship purchased and placed in service in 1991. Under paragraph 
(f) of this section, immediately before the sale G increases the 
adjusted basis of the office equipment by $7,500, the amount of the 
outstanding carryover of disallowed deduction with respect to the office 
equipment.
    Example 2. (i) Assume the same facts as in Example 1, except that G 
notes on the appropriate books and records that G expenses $2,500 of 
section 179 expenses relating to G's sole proprietorship and carries 
forward the remaining $5,000 of section 179 expenses relating to G's 
sole proprietorship and $2,500 of section 179 expenses allocated from 
GD.
    (ii) On January 1, 1992, G sells G's partnership interest to A. 
Under paragraph (h)(2) of this section, immediately before the sale G 
increases the adjusted basis of G's partnership interest by $2,500, the 
amount of the outstanding carryover of disallowed deduction with respect 
to the partnership interest.
