Disclaimer

Informational, not tax advice. EnergyCreditDeadline.us explains the eligibility tests for IRS §25C, §25D, §30D, and §25E and the §6511(a) amend-window mechanics. We do not determine whether your specific install, vehicle, or amended return qualifies — only the IRS does, based on the statutory tests and the documentation you submit on Form 1040-X, Form 5695, or Form 8936.

No professional relationship. Use of this site does not create a CPA-client, attorney-client, EA-client, or fiduciary relationship. The reviewer credential listed on /about indicates editorial review of content; it is not an engagement to represent your individual matter. Verify with the IRS or a licensed CPA, EA, or tax attorney before filing, amending, or responding to an IRS notice.

Source-verified, but moving target. Information on this site is verified against 26 USC §25C, §25D, §30D, §25E, the IRS FS-2025-05 Fact Sheet, and the 2025 Form 5695 / Form 8936 instructions on a quarterly cycle. Re-verification dates appear on every citation pin and on /sources. If a primary source revises and we have not yet caught up, the displayed last-verified date will reflect the older check. Tax law is a moving target; treat anything on this site as a starting point for your own verification, not a final answer.

We do not file returns. We do not contact the IRS for you. We do not file Form 1040-X, Form 5695, Form 8936, or any other IRS form on your behalf. We do not interact with IRS systems on your account. Affiliate tax-prep services may handle return- preparation labor for a fee; the credit-eligibility determination is always made by the IRS based on what you (or your preparer) submit.

Affiliate disclosure. When and if we are approved into the relevant tax-prep affiliate programs (TurboTax via Impact / CJ, TaxAct via CJ, FreeTaxUSA, H&R Block via Impact), we will earn a referral fee when you click an outbound link and purchase a service. This fee does not affect the price you pay, does not affect the IRS's determination of your credit eligibility, and does not affect the primary-source-pinned content on this site. Affiliate links are clearly labeled.

YMYL audience-sensitivity. If you are responding to an IRS correspondence audit, a CP-series notice, or a denied claim — gather your documentation (contractor invoice, install-completion certificate, binding-contract evidence, payment records, manufacturer certification statement, VIN and dealer information), respond by the deadline on the notice, and engage a licensed professional if the amount is material. See /audit-defense for a generic walkthrough.

Privacy. Decoder inputs (install date, contract date, payment date, dollar amount, state) are processed in your browser only and never transmitted to our servers. See /privacy for full disclosure.
