What’s New 

• The energy efficient home credit was 

extended to cover homes sold or leased 

in 2010 and 2011. 

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 ($2,000 or $1,000) 

is based on the energy saving 

requirements of the home. The credit is 

part of the general business credit. 

Taxpayers other than partnerships or 

S corporations, whose only source of 

this credit is from a pass-through entity, 

are not required to complete or file this 

form. Instead, they can report this credit 

directly on line 1p of Form 3800. 

See section 45L for more information. 

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 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 is not 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 2012, for 

use as a residence. The home is also 

required to be certified and meet certain 

energy saving requirements. 

Construction includes substantial 

reconstruction and rehabilitation. 

Energy Saving Requirements 

The amount of the credit is based on the 

extent to which each new energy 

efficient home meets the energy saving 

requirements discussed below.

50% energy efficient standard. 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 2004 

Supplement to the 2003 International 

Energy Conservation Code,

• 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. The 

credit is $1,000 for a manufactured 

home that does not 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:

For Paperwork Reduction Act Notice, see page 2. Cat. No. 37718T Form 8908 (2010) 
Form 8908 (2010) Page 2 

• 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 either 

Residential Energy Services Network 

(RESNET) Publication 05-001, RESNET 

Publication 06-001, or an equivalent 

calculation procedure. You may access 

RESNET publications at 

www.resnet.us/standards/taxcredits/

procedures.pdf. 

Certification 

An eligible contractor must obtain a 

certification that the dwelling unit meets 

the requirements of section 45L(c)(1) 

from an eligible certifier before claiming 

the section 45L credit. The certification 

will be treated as satisfying the 

requirements of section 45L(c)(1) 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, or, for manufactured 

homes, section 3 or section 4 of Notice 

2008-36.
