Editorial Policy: This site publishes educational information about U.S. tax credit transferability and related clean energy credits. We aim to be accurate, plain-English, and transparent about updates. This is not tax or legal advice. See Disclaimer.

Our standards

  • Official-first sourcing: IRS/Treasury, Federal Register, eCFR, and IRS forms/instructions.
  • Plain English: explain what the rule is and what it means operationally.
  • Consistency: the same terms mean the same thing across pages.
  • Corrections: if something is wrong, we fix it and note it (see Updates).
  • Independence: ads do not determine what we publish or how we explain it.

Key navigation


1) Sources we rely on

We prioritize official sources. When a rule is discussed, we link to underlying IRS/Treasury materials whenever possible.

Preferred sources

  • Federal Register: final regulations (authoritative rule text).
  • eCFR: consolidated regulatory text for day-to-day reference.
  • IRS pages: FAQs, registration portal instructions, forms and instructions.
  • IRS publications: official user guides (for example, the registration tool guide).

2) Updates

Tax guidance changes. When we update a page, we fix the content, improve clarity, and update the “Last updated” date. Material changes are summarized on Updates.


3) Corrections

If you think something is wrong, email us with the page URL and a short explanation. We review and correct verified errors.
