General Instructions

Qualified Progress Expenditures

Qualified progress expenditures are those expenditures made
before the property is placed in service and for which the
taxpayer has made an election to treat the expenditures as
progress expenditures. Qualified progress expenditure property
is any property that is being constructed by or for the taxpayer
and which (a) has a normal construction period of 2 years or
more, and (b) it is reasonable to believe that the property will be
new investment credit property in the hands of the taxpayer
when it is placed in service. The placed-in-service requirement
doesn't apply to qualified progress expenditures.
Qualified progress expenditures for:

• Self-constructed property means the amount that is properly

chargeable (during the tax year) to a capital account with respect
to that property; or
• Non-self-constructed property means the lesser of: (a) the
amount paid (during the tax year) to another person for the
construction of the property, or (b) the amount that represents
the proportion of the overall cost to the taxpayer of the
construction by the other person which is properly attributable to
that portion of the construction which is completed during the tax
year.
For more information on qualified progress expenditures, see
section 46(d) (as in effect on November 4, 1990). For details on
qualified progress expenditures for the rehabilitation credit, see
section 47(d).

At-Risk Limit for Individuals and
Closely Held Corporations

Purpose of Form

Use Form 3468 to claim the investment credit. The investment
credit consists of the rehabilitation, energy, qualifying advanced
coal project, qualifying gasification project, and qualifying
advanced energy project credits. If you file electronically, you
must send in a paper Form 8453, U.S. Individual Income Tax
Transmittal for an IRS e-file Return, if attachments are required
to Form 3468.

Investment Credit Property

Investment credit property is any depreciable or amortizable
property that qualifies for the rehabilitation credit, energy credit,
qualifying advanced coal project credit, qualifying gasification
project credit, or qualifying advanced energy project credit.
You can't claim a credit for property that is:
• Used mainly outside the United States (except for property
described in section 168(g)(4));
• Used by a governmental unit or foreign person or entity
(except for a qualified rehabilitated building leased to that unit,
person, or entity; and property used under a lease with a term of
less than 6 months);
• Used by a tax-exempt organization (other than a section 521
farmers' cooperative) unless the property is used mainly in an
Jan 13, 2022

unrelated trade or business or is a qualified rehabilitated building
leased by the organization;
• Used for lodging or in the furnishing of lodging (see section
50(b)(2) for exceptions); or
• Certain MACRS business property to the extent it has been
expensed under section 179.

The cost or basis of property for investment credit purposes may
be limited if you borrowed against the property and are protected
against loss, or if you borrowed money from a person who is
related or who has an interest (other than as a creditor) in the
business activity. The cost or basis must be reduced by the
amount of the nonqualified nonrecourse financing related to the
property as of the close of the tax year in which the property is
placed in service. If, at the close of a tax year following the year
property was placed in service, the nonqualified nonrecourse
financing for any property has increased or decreased, then the
credit base for the property changes accordingly. The changes
may result in an increased credit or a recapture of the credit in
the year of the change. See sections 49 and 465 for details.

Recapture of Credit

You may have to refigure the investment credit and recapture all
or a portion of it if:
• You dispose of investment credit property before the end of 5
full years after the property was placed in service (recapture
period);
• You change the use of the property before the end of the
recapture period so that it no longer qualifies as investment
credit property;

Cat. No. 12277P

• The business use of the property decreases before the end of
the recapture period so that it no longer qualifies (in whole or in
part) as investment credit property;
• Any building to which section 47(d) applies will no longer be a
qualified rehabilitated building when placed in service;
• Any property to which section 48(b), 48A(b)(3), 48B(b)(3), or
48C(b)(2) applies will no longer qualify as investment credit
property when placed in service;
• Before the end of the recapture period, your proportionate
interest is reduced by more than 1/3 in an S corporation,
partnership, estate, or trust that allocated the cost or basis of
property to you for which you claimed a credit;
• You return leased property (on which you claimed a credit) to
the lessor before the end of the recapture period;
• A net increase in the amount of nonqualified nonrecourse
financing occurs for any property to which section 49(a)(1)
applied;
• A grant under section 1603 of the American Recovery and
Reinvestment Tax Act of 2009 (Section 1603 grant) was made
for section 48 property for which a credit was allowed for
progress expenditures before the grant was made. Recapture is
applicable to those amounts previously included in the qualified
basis for an energy credit, including progress expenditures, that
also are the basis for the Section 1603 grant; or
• A grant under section 9023 of the Patient Protection and
Affordable Care Act was made for investment for which a credit
was determined under section 48D (as in effect before its repeal
on March 23, 2018) before the grant was made.

Exceptions to recapture. Recapture of the investment credit
doesn't apply to any of the following.
1. A transfer due to the death of the taxpayer.
2. A transfer between spouses or incident to divorce under
section 1041. However, a later disposition by the transferee is
subject to recapture to the same extent as if the transferor had
disposed of the property at the later date.
3. A transaction to which section 381(a) applies (relating to
certain acquisitions of the assets of one corporation by another
corporation).
4. A mere change in the form of conducting a trade or
business if:
a. The property is retained as investment credit property in
that trade or business, and
b. The taxpayer retains a substantial interest in that trade or
business.

Part I. Information Regarding the Election To
Treat the Lessee as the Purchaser of Investment
Credit Property

Generally, for purposes of eligibility for and figuring the amount
of the investment credit, a lessor of property may elect to treat
the lessee as having acquired the property. Once the election is
made, the lessee will be entitled to an investment credit for that
property for the tax year in which the property is placed in
service and the lessor generally will not be entitled to such a
credit.
If the leased property is disposed of, or otherwise ceases to
be investment credit property, the property generally will be
subject to the recapture rules for early dispositions.
The lessor will provide the lessee with all the information
needed to complete lines 11h and 11i, if applicable.

A mere change in the form of conducting a trade or business
includes a corporation that elects to be an S corporation and a
corporation whose S election is revoked or terminated.

For information on making the election, see section 48(d) (as
in effect on November 4, 1990) and related regulations. For
limitations, see sections 46(e)(3) and 48(d) (as in effect on
November 4, 1990).

For more information, see the Instructions for Form 4255.
See section 46(g)(4) (as in effect on November 4, 1990),
and related regulations, if you made a withdrawal from a
CAUTION capital construction fund set up under the Merchant
Marine Act of 1936 to pay the principal of any debt incurred in
connection with a vessel on which you claimed investment
credit.

Line 5b
Enter the qualified investment in advanced coal-based
generation technology property placed in service during the tax
year for projects described in section 48A(d)(3)(B)(ii). Eligible
property is any property that is part of a qualifying advanced coal
project (defined earlier) not using an integrated gasification
combined cycle.

Qualifying Advanced Coal Project Credit

A qualifying advanced coal project is a project that:
• Uses advanced coal-based generation technology (as
defined in section 48A(f)) to power a new electric generation unit
or to refit or repower an existing electric generation unit
(including an existing natural gas-fired combined cycle unit);
• Has fuel input which, when completed, will be at least 75%
coal;
• Has an electric generation unit or units at the site that will
generate at least 400 megawatts;
• Has a majority of the output that is reasonably expected to be
acquired or utilized;
• Is to be constructed and operated on a long-term basis when
the taxpayer provides evidence of ownership or control of a site
of sufficient size;
• Will be located in the United States; and
• Includes equipment that separates and sequesters at least
65% (70% in the case of an application for reallocated credits) of
the project's total carbon dioxide emissions for project
applications described in section 48A(d)(2)(A)(ii).

Line 5c
Enter the qualified investment in advanced coal-based
generation technology property placed in service during the tax
year for projects described in section 48A(d)(3)(B)(iii). Eligible
property is any certified property located in the United States
and that is part of a qualifying advanced coal project (defined
earlier) which has equipment that separates and sequesters at
least 65% of the project's total carbon dioxide emissions. This
percentage increases to 70% if the credits are later reallocated
by the IRS.
The credit will be recaptured if a project fails to attain or
maintain the carbon dioxide separation and sequestration
requirements. For details, see section 48A(i) and Notice
2011-24, 2011-14 I.R.B. 603, available at IRS.gov/irb/
2011-14_IRB#NOT-2011-24.

For more information on the new allocation round for section
48A credits, see Notice 2020-88, 2020-53 I.R.B. 1795, available
at IRS.gov/irb/2020-53_IRB#NOT-2020-88.

Qualifying Gasification Project Credit

Basis. Qualified investment for any tax year is the basis of
eligible property placed in service by the taxpayer during the tax
year which is part of a qualifying advanced coal project. Eligible
property is limited to property which can be depreciated or
amortized and which was constructed, reconstructed, or erected
and completed by the taxpayer; or which is acquired by the
taxpayer if the original use of such property commences with the
taxpayer.

A qualifying gasification project is a project that:
• Employs gasification technology (as defined in section 48B(c)
(2)),
• Is carried out by an eligible entity (as defined in section 48B(c)
(7)), and
• Includes a qualified investment of which an amount not to
exceed $650 million is certified under the qualifying gasification
program as eligible for credit.

Basis reduction for certain financing. If property is financed
in whole or in part by subsidized energy financing or by
tax-exempt private activity bonds, the amount that you can claim
as basis is the basis that would otherwise be allowed multiplied
by a fraction that is 1 reduced by a second fraction, the
numerator of which is that portion of the basis allocable to such
financing or proceeds, and the denominator of which is the basis
of the property. For example, if the basis of the property is
$100,000 and the portion allocable to such financing or
proceeds is $20,000, the fraction of the basis that you may claim
the credit on is 4/5 (that is, 1 minus $20,000/$100,000).
Subsidized energy financing means financing provided under a
federal, state, or local program, a principal purpose of which is to
provide subsidized financing for projects designed to conserve
or produce energy.

The total amount of credits that may be allocated under the
qualifying gasification project program may not exceed $600
million.
For more information on the qualifying gasification project
and the qualifying gasification program, see Notice 2009-23,
2009-16 I.R.B. 802, available at IRS.gov/irb/
2009-16_IRB#NOT-2009-23, which is amplified by Notice
2014-81, 2014-53 I.R.B. 1001, available at IRS.gov/irb/
2014-53_IRB#NOT-2014-81. Also, see Notice 2011-24.
Basis reduction. If property is financed in whole or in part by
subsidized energy financing or by tax-exempt private activity
bonds, figure the credit by using the basis of such property
reduced under the rules described in Basis reduction for certain
financing, earlier.

Line 5a

Line 6a

Enter the qualified investment in integrated gasification
combined cycle property placed in service during the tax year for
projects described in section 48A(d)(3)(B)(i). Eligible property is
any property which is part of a qualifying advanced coal project
using an integrated gasification combined cycle and is
necessary for the gasification of coal, including any coal
handling and gas separation equipment.

Enter the qualified investment in qualifying gasification project
property (defined above) placed in service during the tax year for
which credits were allocated or reallocated after October 3,
2008, and that includes equipment that separates and
sequesters at least 75% of the project's carbon dioxide
emissions. Qualified investment is the basis of eligible property
placed in service during the tax year that is part of a qualifying
gasification project.

Integrated gasification combined cycle is an electric
generation unit that produces electricity by converting coal to
synthesis gas, which in turn is used to fuel a combined cycle
plant to produce electricity from both a combustion turbine
(including a combustion turbine/fuel cell hybrid) and a steam
turbine.

Instructions for Form 3468 (2021)

For purposes of this credit, eligible property includes any
property that is part of a qualifying gasification project and
necessary for the gasification technology of such project. The
IRS is required to recapture the benefit of any allocated credit if a
project fails to attain or maintain these carbon dioxide separation
and sequestration requirements. See section 48B(f) and Notice
2011-24.

Credit From Cooperatives
Line 9

Qualifying Advanced Energy Project Credit

Patrons, including cooperatives that are patrons in other
cooperatives, enter the unused investment credit from the
qualifying advanced coal project credit, qualifying gasification
project credit, or qualifying advanced energy project credit
allocated from cooperatives. If you are a cooperative, see the
instructions for Form 3800, Part III, line 1a, for allocating the
investment credit to your patrons.

To be eligible for the qualifying advanced energy project credit,
some or all of the qualified investment in the qualifying advanced
energy project must be certified by the IRS under section
48C(d). For more information on certification, see Notice
2009-72, 2009-37 I.R.B. 325, available at IRS.gov/irb/

Rehabilitation Credit

Line 7

You are allowed a credit for qualified rehabilitation expenditures
made for any qualified rehabilitated building. You must reduce
your basis by the amount of the credit determined for the tax
year. See Regulations section 1.47-7.

Enter the qualified investment in qualifying advanced energy
project property placed in service during the tax year. Qualified
investment is the basis of eligible property placed in service
during the tax year that is part of a qualifying advanced energy
project.

If the adjusted basis of the building is determined in whole or
in part by reference to the adjusted basis of a person other than
the taxpayer, see Regulations section 1.48-12(b)(2)(viii) for
additional information that must be attached.

Qualifying advanced energy project means a project that
re-equips, expands, or establishes a manufacturing facility for
the production of:
• Property designed to be used to produce energy from the sun,
wind, geothermal deposits (within the meaning of section 613(e)
(2)), or other renewable resources;
• Fuel cells, microturbines, or an energy storage system for use
with electric or hybrid-electric motor vehicles;
• Electric grids to support the transmission of intermittent
sources of renewable energy, including storage of the energy;
• Property designed to capture and sequester carbon dioxide
emissions;
• Property designed to refine or blend renewable fuels or to
produce energy conservation technologies (including
energy-conserving lighting technologies and smart grid
technologies);
• New qualified plug-in electric drive motor vehicles (as defined
in section 30D), or components that are designed specifically for
use with those vehicles, including electric motors, generators,
and power control units; and
• Other advanced energy property designed to reduce
greenhouse gas emissions.

Qualified Rehabilitated Building
To be a qualified rehabilitated building, your building must meet
all five of the following requirements.
1. The building must be a certified historic structure. A
certified historic structure is any building (a) listed in the National
Register of Historic Places, or (b) located in a registered historic
district (as defined in section 47(c)(3)(B)) and certified by the
Secretary of the Interior as being of historic significance to the
district. Certification requests are made through your State
Historic Preservation Officer on National Park Service (NPS)
Form 10-168, Historic Preservation Certification Application. The
request for certification should be made prior to physical work
beginning on the building. For pre-1936 buildings under the
transition rule, see Transitional rule for amounts paid or incurred
after 2017, later.
2. The building must be substantially rehabilitated. A
building is considered substantially rehabilitated if your qualified
rehabilitation expenditures during a self-selected 24-month
period that ends with or within your tax year are more than the
greater of $5,000 or your adjusted basis in the building and its
structural components. Figure adjusted basis on the first day of
the 24-month period or the first day of your holding period,
whichever is later. If you are rehabilitating the building in phases
under a written architectural plan and specifications that were
completed before the rehabilitation began, substitute “60-month
period” for “24-month period.”
3. Depreciation must be allowable with respect to the
building. Depreciation isn't allowable if the building is
permanently retired from service. If the building is damaged, it
isn't considered permanently retired from service where the
taxpayer repairs and restores the building and returns it to actual
service within a reasonable period of time.
4. The building must have been placed in service before the
beginning of rehabilitation. This requirement is met if the building
was placed in service by any person at any time before the
rehabilitation began.
5. For a building under the transition rule, (a) at least 75% of
the external walls must be retained with 50% or more kept in
place as external walls, and (b) at least 75% of the existing
internal structural framework of the building must be retained in
place.

A qualifying advanced energy project doesn't include any
portion of a project for the production of any property that is used
in the refining or blending of any transportation fuel (other than
renewable fuels).
Eligible property. Eligible property is property that is
necessary for the production of property described in section
48C(c)(1)(A)(i), for which depreciation or amortization is
available and is tangible personal property or other tangible
property (not including a building or its structural components),
but only if the property is used as an integral part of the
qualifying advanced energy project.
Transitional rule. Enter only the basis:
• Attributable to construction, reconstruction, or erection by the
taxpayer after February 17, 2009;
• Of property acquired and placed in service after February 17,
2009; and
• Only to the extent of the qualified investment (as determined
under section 46(c) and (d) as in effect on November 4, 1990)
with respect to qualified progress expenditures made after
February 17, 2009.

period, or the 60-month period, referred to in subparagraph (b)
ends.
If you have more than one property that qualifies for the
rehabilitation credit, attach a schedule showing the type of
property (pre-1936 building or certified historic structure), NPS
number, date of final certification, and the partnership employer
identification number (EIN), if applicable. Also, indicate if the
transitional rule applies.

Qualified Rehabilitation Expenditures
To be qualified rehabilitation expenditures, your expenditures
must meet all six of the following requirements.
1. The expenditures must be for (a) nonresidential real
property, (b) residential rental property (but only if a certified
historic structure; see Regulations section 1.48-1(h)), or (c) real
property that has a class life of more than 12.5 years.
2. The expenditures must be incurred in connection with the
rehabilitation of a qualified rehabilitated building.
3. The expenditures must be capitalized and depreciated
using the straight line method.
4. The expenditures can't include the costs of acquiring or
enlarging any building.
5. If the expenditures are in connection with the
rehabilitation of a certified historic structure or a building in a
registered historic district, the rehabilitation must be certified by
the Secretary of the Interior as being consistent with the historic
character of the property or district in which the property is
located. This requirement doesn't apply to a building in a
registered historic district if (a) the building isn't a certified
historic structure, (b) the Secretary of the Interior certifies that
the building isn't of historic significance to the district, and (c) if
the certification in (b) occurs after the rehabilitation began, the
taxpayer certifies in good faith that he or she wasn't aware of that
certification requirement at the time the rehabilitation began.
6. The expenditures can't include any costs allocable to the
part of the property that is (or may reasonably be expected to
be) tax-exempt use property (as defined in section 168(h) except
that “50 percent” shall be substituted for “35 percent” in
paragraph (1)(B)(iii)). This exclusion doesn't apply for line 11d.

Line 11h
If you are claiming a credit for a certified historic structure on
line 11f or 11g, enter the assigned NPS project number on
line 11h. If the qualified rehabilitation expenditures are from an S
corporation, partnership, estate, or trust, enter on line 11h the
EIN of the pass-through entity instead of the assigned NPS
project number, and skip line 11i and the instructions below.
The lessor will provide the lessee with the NPS project
number to enter on line 11h.

Line 11i
Enter the date of the final certification of completed work
received from the Secretary of the Interior on line 11i. If the final
certification hasn't been received by the time the tax return is
filed for a year in which the credit is claimed, attach a copy of the
first page of NPS Form 10-168, Historic Preservation
Certification Application (Part 2—Description of Rehabilitation),
with an indication that it was received by the Department of the
Interior or the State Historic Preservation Officer, together with
proof that the building is a certified historic structure (or that such
status has been requested). After the final certification of
completed work has been received, file Form 3468 with the first
income tax return filed after receipt of the certification and enter
the assigned NPS project number and the date of the final
certification of completed work on the appropriate lines on the
form. Also, attach an explanation and indicate the amount of
credit claimed in prior years.

Line 11
For credit purposes, the expenditures generally are taken into
account for the tax year in which the qualified rehabilitated
building is placed in service. However, with certain exceptions,
you may elect to take the expenditures into account for the tax
year in which they were paid (or, for a self-rehabilitated building,
when capitalized) if (a) the normal rehabilitation period for the
building is at least 2 years, and (b) it is reasonable to expect that
the building will be a qualified rehabilitated building when placed
in service. For details, see section 47(d). To make this election,
check the box on line 11a. The credit, as a percent of
expenditures paid or incurred during the tax year for any
qualified rehabilitated building, depends on the type of structure
and its location.

If you fail to receive final certification of completed work prior
to the date that is 30 months after the date that you filed the tax
return on which the credit was claimed, you must submit a
written statement to the IRS stating that fact before the last day
of the 30th month. You will be asked to consent to an agreement
under section 6501(c)(4) extending the period of assessment for
any tax relating to the time for which the credit was claimed.

Transitional rule for amounts paid or incurred after 2017.
The 10% credit for pre-1936 buildings no longer applies and the
20% credit for a certified historic structure is modified generally
to allow 100% of qualified rehabilitation expenditures ratably
over a 5-year period for amounts paid or incurred after 2017. For
qualified rehabilitation expenditures paid or incurred during the
transitional period stated below, the taxpayer can claim the 10%
credit for pre-1936 buildings and the 20% credit for a certified
historic structure (under section 47(a), as in effect before
December 22, 2017). The transitional rule applies to amounts
paid or incurred as follows.
In the case of qualified rehabilitation expenditures with
respect to any building (a) owned or leased by the taxpayer
during the entirety of the period after 2017, and (b) with respect
to which the 24-month period selected by the taxpayer under
clause (i) of section 47(c)(1)(B) (as in effect after December 21,
2017), or the 60-month period applicable under clause (ii) of

1603 grant for new investment in the property for which you are
claiming the energy credit.
4. A declaration, applicable to the statement and any
accompanying documents, signed by you, or signed by a person
currently authorized to bind you in such matters, in the following
form: “Under penalties of perjury, I declare that I have examined
this statement, including accompanying documents, and to the
best of my knowledge and belief, the facts presented in support
of this statement are true, correct, and complete.”

Note. The transitional rules of section 48(m) (as in effect on
November 4, 1990) apply to offshore wind facilities for periods
after December 31, 2016. Under the transitional rules of section
48(m) (as in effect on November 4, 1990), the phaseout of the
section 48 credit provided for other types of qualified investment
credit facilities at section 48(a)(5)(E), does not apply to offshore
wind facilities.
A qualified investment credit facility is a facility that:

• Is a qualified facility under section 45(d)(1), (2), (3), (4), (6),

(7), (9), or (11) that is placed in service after 2008 and the
construction of which began before January 1, 2022. See When
