Internal Revenue Bulletin 2008-12 · 2026-10-03 edition · updated 2026-10-04 · United States

CLAIM THE $1,000 CREDIT

.01 Certified Homes . Except as provided in section 4.02 of this notice, an eligible contractor must obtain the certification required under § 45L(c)(3)(A) with respect to a manufactured home from an eligible certifier before claiming the $1,000 energy efficient home credit with respect to the manufactured home. An eligible contractor is not required to attach the certification to the return on which the credit is claimed. However, § 1.6001–1(a) requires that taxpayers maintain such books and records as are sufficient to establish the entitlement to, and amount of, any credit claimed by the taxpayer. Accordingly, an eligible contractor claiming a $1,000 credit under § 45L should retain the certification as part of the eligible contractor’s records to satisfy this requirement. The certification will be treated as satisfying the requirements of § 45L(c)(3)(A) if all construction has been performed in a manner consistent with the design specifications provided to the eligible certifier and the certification contains all of the following:
