Statutory background
As amended by the Inflation Reduction Act of 2022, Section 25C provides a nonrefundable credit to individual taxpayers of 30% of the sum of amounts paid or incurred during a tax year for (1) qualified energy efficiency improvements, (2) residential energy property expenditures, and (3) home energy audits. The credit is subject to dollar limitations based on the type of improvement, an annual limitation of $1,200, and other requirements. The 2022 amendments generally apply to property placed in service after 2022 and before 2033.
Effective for property placed in service after 2024, each item of certain types of property eligible for a Section 25C credit (specified property) must be produced by a qualified manufacturer and have an assigned qualified PIN. “Specified property” is certain heat pumps, air conditioners, and hot water heaters; other furnaces and hot water boilers; advanced main air circulating fans; exterior windows and skylights; and exterior doors.
A “qualified PIN” is a PIN assigned to an item of specified property by a qualified manufacturer using a methodology that ensures that each number is unique, for example by using numbers or letters unique to that manufacturer. A “qualified manufacturer” is a manufacturer of specified property that enters into an agreement with Treasury to assign a PIN to each item of specified property using the required methodology, label each item with its PIN, and submit periodic written reports.
