Instructions for Form 8908

Department of the Treasury
Internal Revenue Service

(Rev. December 2022)

Energy Efficient Home Credit
Section references are to the Internal Revenue Code
unless otherwise noted.

General Instructions
Future Developments

For the latest information about developments related to
Form 8908 and its instructions, such as legislation
enacted after they were published, go to IRS.gov/
Form8908.

What’s New
Credit extension. The Inflation Reduction Act of 2022
(IRA 2022) extended the energy efficient home credit to
cover qualified new energy efficient homes sold or leased
after 2021 and before 2033.
Credit increase and modification. IRA 2022 also
increased and modified the credit for certain homes sold
or leased after 2022.

Purpose of Form

Eligible contractors use Form 8908 to claim a credit for
each qualified energy efficient home sold or leased to
another person during the tax year for use as a residence.
The credit is based on the energy saving requirements of
the home. The credit is part of the general business credit.

Partnerships and S corporations must file this form to
claim the credit. All other taxpayers aren’t required to
complete or file this form if their only source for this credit
is a partnership or an S corporation. Instead, they can
report this credit directly on line 1p in Part III of Form 3800,
General Business Credit.
See section 45L for more information.

What Revision To Use

Use the December 2022 revision of Form 8908 for tax
years beginning in 2022 or later, until a later revision is
issued. Use this December 2022 revision of the
instructions for tax years beginning in 2022 or later, until a
later revision is issued. Use prior revisions of the form and
instructions for earlier tax years. All revisions are available
at IRS.gov/Form8908.

Who May Claim the Credit

Eligible contractors may claim the credit for new energy
efficient homes that are acquired by sale or lease by an
individual from that contractor during the tax year for use
as a residence.

Definitions
Eligible Contractor

An eligible contractor is the person that constructed a
qualified energy efficient home (or produced a qualified
energy efficient home that is a manufactured home). A
Nov 04, 2022

person must own and have a basis in the qualified energy
efficient home during its construction to qualify as an
eligible contractor with respect to the home. For example,
if the person that hires a third-party contractor to construct
the home owns and has the basis in the home during
construction, the person that hires the third-party
contractor is the eligible contractor and the third-party
contractor isn’t an eligible contractor.

Qualified New Energy Efficient Home

A qualified new energy efficient home is a dwelling unit
located in the United States, whose construction is
substantially completed after August 8, 2005, and sold or
leased to another person after 2005 but before 2033, for
use as a residence. The home must be certified and meet
certain energy saving requirements. Construction includes
substantial reconstruction and rehabilitation.

Energy Saving Requirements

The credit amount is based on the extent to which each
new energy efficient home meets the energy saving
requirements discussed below.
50% energy efficient standard (for homes sold or
leased before 2023). The credit is $2,000 for a dwelling
unit that is certified to have an annual level of heating and
cooling energy consumption at least 50% below the
annual level of heating and cooling energy consumption of
a comparable dwelling unit and has building envelope
component improvements that account for at least 1/5 of
the 50% reduction in energy consumption. A
manufactured home meeting the requirements described
above and the Federal Manufactured Home Construction
and Safety Standards (FMHCSS) requirements (see 24
C.F.R. part 3280) is also eligible for the $2,000 credit.
Comparable dwelling unit. A comparable dwelling
unit:
• Is constructed in accordance with the standards of
chapter 4 of the 2006 International Energy Conservation
Code as such Code (including supplements) was in effect
on January 1, 2006;
• Has air conditioners with a Seasonal Energy Efficiency
Ratio (SEER) of 13, measured in accordance with 10
C.F.R. 430.23(m); and
• Has heat pumps with a SEER of 13 and a Heating
Seasonal Performance Factor (HSPF) of 7.7, measured in
accordance with 10 C.F.R. 430.23(m).
30% energy efficient standard (for homes sold or
leased before 2023). The credit is $1,000 for a
manufactured home that doesn’t meet the 50% energy
saving requirement but is certified to have an annual
level of heating and cooling energy consumption at least
30% below the annual level of heating and cooling energy
consumption of a comparable dwelling unit (discussed
above) and:
• Meets FMHCSS requirements, and

• Has building envelope component improvements that
account for at least 1/3 of the 30% reduction in energy
consumption, or
• Meets the current requirements established by the
Administrator of the Environmental Protection Agency
under the Energy Star Labeled Homes program.
Heating and cooling energy and cost savings must be
calculated using the procedures described in Residential
Energy Services Network (RESNET) Publication 001-16,
or an equivalent calculation procedure. You can access
RESNET publications at http://staging.resnet.us/
professional/standards/tax_credits.

Certification

An eligible contractor must obtain a certification that the
dwelling unit meets the requirements of section 45L(c)
before claiming the section 45L credit. For homes sold or
leased before 2023, the certification will be treated as
satisfying the requirements of section 45L(c) if all the
construction has been performed in a manner consistent
with the design specifications provided to the eligible
certifier and the certification contains all of the information
required by section 3 of Notice 2008-35, available at
IRS.gov/irb/2008-12_IRB#NOT-2008-35; or, for
manufactured homes, section 3 or section 4 of Notice
2008-36, available at IRS.gov/irb/
2008-12_IRB#NOT-2008-36.

Zero Energy Ready Home Program requirement (for
homes sold or leased after 2022). A dwelling unit
meets this requirement if the dwelling unit is certified as a
zero energy ready home under the Zero Energy Ready
Home Program of the Department of Energy as in effect
on January 1, 2023 (or any successor program).
Information about this program is available at
www.energy.gov.

For homes sold or leased after 2022, any additional
guidance issued to address certification will be added to
these instructions at a later date.
