What can I claim on New Most efficient Windows and receive my tax credit in 2023?
Simplified you can take a credit for 30% of your job with a maximum of $600, SO what is available is $600 credit for upgrading your purchase to Windows that qualify as "Most Efficient" under the new 2023 Energy Star Program. These windows however will be much, much, much more expensive and that $600 won't go very far in immediate savings or long term payback on energy consumption.
