Editor note:This post's original figures (26% by 12/31/2022, 22% by 12/31/2023) are outdated and must be replaced with current, verified guidance before publishing. Presented here as a legacy placeholder with an outdated-info notice — do not migrate the old percentages.
This article originally covered the federal residential Investment Tax Credit for geothermal and solar. The percentages and expiration dates published on the legacy site are no longer accurate, and the residential credit landscape has since changed materially.
Rather than reprint outdated figures, we've held this post pending an updated write-up from current IRS guidance. For commercial projects, see the 30% Section 48 Investment Tax Credit summarized on our Commercial pages.
If you need current residential guidance today, contact us directly and we'll walk you through what applies to your project as of the date of your install.
