(h) In the case of a geothermal heat pump property, a statement that the property meets the requirements of the Energy Star program that are in effect at the time that the expenditure for such equipment is actually made.

(5) Content of Manufacturer’s Certifi- cation; Required Declaration . A manufacturer’s certification statement must contain a declaration, signed by a person currently authorized to bind the manufacturer in these matters, in the following form:

“Under penalties of perjury, I declare that I have examined this certification statement, and to the best of my knowledge and belief, the facts presented are true, correct, and complete.”

(6) Manufacturer’s Records . A manufacturer that certifies to a taxpayer that a property meets a requirement that must be satisfied to claim the credit under § 25D must retain in its records documentation establishing that the property meets the requirement. The manufacturer must, upon request, make such documentation available for inspection by the Service.

(7) Effect of Erroneous Certification or Failure to Satisfy Documentation Re- quirements. The Service may, upon examination (and after any appropriate consultation with the Department of Energy or the Environmental Protection Agency), determine that a manufacturer’s certification that property meets a requirement that must be satisfied to claim the credit under § 25D is erroneous. In that event, or if the property’s manufacturer fails to satisfy the requirements relating to documentation in section 3.02(6) of this notice, the manufacturer’s right to provide a certification on which future purchasers of the property can rely will be withdrawn, and taxpayers purchasing the property after the date on which the Service publishes an announcement of the withdrawal may not rely on the manufacturer’s certification.

(2) Qualifying Dwelling Unit . (a) Except as provided in section 3.01(2)(b) of this notice, a qualifying dwelling unit is a dwelling unit that is located in the United States and is used as a residence by the taxpayer.

(b) For purposes of section 3.01(1)(c) of this notice (relating to qualified fuel cell property expenditures), a qualifying dwelling unit is a dwelling unit that is located in the United States and is used as a principal residence (within the meaning of section 121) by the taxpayer.

.02 Manufacturer’s Certification (1) In General . The manufacturer of property may certify to a taxpayer that the property meets certain requirements that must be satisfied to claim the credit under § 25D by providing the taxpayer with a certification statement that satisfies the requirements of section 3.02(3), (4) and (5) of this notice. The manufacturer may provide the certification statement by including a written copy of the statement with the packaging of the property, in printable form on the manufacturer’s website, or in any other manner that will permit the taxpayer to retain the certification statement for tax recordkeeping purposes.

(2) Taxpayer Reliance. Except as provided in section 3.02(7) of this notice, a taxpayer may rely on a manufacturer’s certification in determining whether property is eligible for the credit under § 25D.

A taxpayer is not required to attach the certification statement to the return on which the credit is claimed. However, § 1.6001–1(a) of the Income Tax Regulations 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, a taxpayer claiming a credit for residential energy efficient property should retain the certification statement as part of the taxpayer’s records for purposes of § 1.6001–1(a).
