Hi @jo88shar
This credit is claimed in the year you have the windows installed. The credit is limited so the amount you have paid off does not matter in this case.
WHAT IS THE TAX CREDIT FOR WINDOW REPLACEMENT?
If you replaced your old windows with new energy-efficient windows, skylights, doors, or other qualifying items in 2022, you could be eligible to claim a windows tax credit of up to $600. Current energy tax credits for window replacement have been extended until December 31, 2032.
If you have further questions please reply below.
