I seem to not be getting the full $600 credit for my energy efficient window upgrades. It seems to be capped at $200, which was the credit limit for the 2022 tax year.

The Form 5695 for the Residential Energy Credit is not yet finalized for 2023.  It is expected to be finalized for use tomorrow, 02/08.

The problem could be a couple of things. 1. The credit reduces your tax liability and you may have other credits also lowering your tax liability to where you have zeroed out. Take a look at your 5695 and double check your entries, a typo can cause issues. Make sure the form is filled out correctly and then look at your Form 1040 for the tax liability and credits.

2. The form may not be finalized. Please check forms availability here. Select online, Windows, or Macintosh from the drop down menu.
