Deductions & credits

You would enter the amount you paid for the project.  Taking a loan out to pay for it doesn't affect the credit. 

These are entered in the Deductions & Credits section:

  • With your return open, search for energy improvements in the program search box. (Don't search for "energy credit," as this will take you to the wrong place in the program.)
  • Click Jump to energy improvements in the search results.
  • At the bottom of the Energy-Saving Home Improvements screen, answer Yes and click Continue.
  • Follow the on-screen instructions.

If that doesn't work:  Go directly to the Federal Taxes tab, then Deductions & Credits, then Your Home, then scroll to Home Energy Credits.

Note: The Residential Energy Efficient Property Credit is what is called a "non-refundable" credit which means it will only reduce your tax liability to zero.  Any remainder can be carried forward to the next year.
