The IRS announced that it will propose regulations to implement the product identification number (PIN) requirement with respect to the energy efficient home improvement credit. Beginning Jan. 1, 2023, the credit (subject to certain limits and caps) is equal to 30% of the total amount paid for certain qualified expenses. These include qualified energy efficiency improvements, residential energy property expenses and home energy audits. Beginning in 2025, taxpayers claiming the credit must also satisfy a PIN requirement for certain products. Specifically, an item will only qualify for the credit if it is produced by a qualified manufacturer and a PIN is included on the taxpayer’s return.
