Energy Efficient Home Improvement Credit

[dsjack]

We got a contract to buy energy efficient window replacements in November of 2024.  The window company charged us for part of the contract in 2024 and the rest in 2025 when the work was done.  Do I take the energy efficient home improvement credit in 2024 or 2025.

You can take the credit in 2025 after the windows are installed and the work is complete.
