Who reviews this site

EnergyCreditDeadline.us is a statute-pinned information hub for the four IRS clean-energy credits accelerated to termination by the One Big Beautiful Bill (P.L. 119-21): §25C Energy Efficient Home Improvement, §25D Residential Clean Energy, §30D New Clean Vehicle, and §25E Previously-Owned Clean Vehicle. Every credit-percentage claim, every dollar cap, and every IRS form-line reference traces to a primary source on irs.gov, treasury.gov, or law.cornell.edu.

Why this site exists

The 3-year amend window is open. Most explainers stop at “the credit ended.”

The four credits ended in 2025 under OBBBA. But §6511(a) keeps the amend window open for ~3 years from the original return-filing date — meaning a 2025 install that qualified under the installation-completion test, or a 2025 EV that qualified under the binding-contract acquisition test, can still be claimed (or re-claimed correctly) on an amended return through roughly 2029.

What households actually need is the conditional-logic answer: given your install date, contract date, payment date, and placed-in-service date, does the credit apply, and on which IRS form line do you report it. That is what the decoder does. That is why this site exists.
