Energy tax credits and incentives

Start with the applicable date and technology

Energy incentives are date-sensitive. The current-law overview explains the §25C, §25D, §30D, §45L, §48E, and §179D rules summarized in the reviewed reference library, including beginning-of-construction and placed-in-service questions.

The legacy detail pages below are retained for topic coverage but require current-law review. Do not rely on a detail page without confirming the relevant statute, dates, eligibility, and project facts.

Begin with the current-law overview, then use the topic links to identify the incentive that may apply to a particular building, vehicle, production activity, or investment. Similar technologies can fall under different rules, and eligibility may depend on construction, acquisition, or placed-in-service dates. Confirm those facts before estimating a benefit or making a project decision.
