How we verify

Every rebate figure on this site — amount, who qualifies, until when — is read on the official page of the program that pays it, on the day the page is written or re-checked, and the page shows that date. Where the official page does not prove today's status, we say so instead of guessing. This page describes that method as it actually runs.

1. Official source, on the day

A "source" means the page published by the body that pays or administers the money: a state energy office, a utility, a public utility district, the IRS or the U.S. Department of Energy. Guides, contractor pages, directories and AI answers are not sources; when they disagree with the official page, the disagreement goes into the corrections log. Each state page and each deadline names its source and links to it.

2. Verified means read, not remembered

The registry behind rebates by state has 51 rows. A row is marked verified only when its status, notes and programs were written from the official state page on the date shown — today 23 of 51 rows. The other 28 rows come from our first registry (September 20, 2026, secondary sources) and are labelled "not yet verified" on their pages, with instructions for confirming the status yourself. A status is never carried over from an earlier reading: each re-check starts from the official page again. The most recent official verification is dated September 27, 2026.

3. What a figure must carry

A rebate amount appears only with the answers to four questions: how much, who pays it, until when, and where the official rule is published. Amounts that a utility publishes only through contractors (not on a static official page) are shown with that attribution and a visible note to confirm them in writing before signing. A tax credit is called expired only on the revenue department's page or the statute itself; where the official position is unclear, the page says "ask a tax preparer".

4. Deadlines have one source

All 25 deadlines on the site live in one file, and from it we generate the deadlines page, the calendar you can subscribe to, the per-deadline calendar files and the CSV and JSON downloads. Today 15 are upcoming and 5 are promised without a date, listed as "undated" rather than given a guess. A deadline moves to "passed" only when we re-check it after the date; nothing is deleted.

5. Corrections are public, ours included

The corrections log holds 35 entries: 5 to our own pages, 3 to our own registry, 3 on official pages that contradict themselves or the law, and 24 in guides, contractor pages or AI answers. Each entry records what was claimed, what the official source says, the source, the date and the re-check. A correction is never removed; a wrong correction is repaired with a new entry. Every correction also appears on the state page it concerns and in the site feed.

6. Data is open, pages are dated

The registry, the deadlines and the corrections are published as CSV and JSON under CC BY 4.0, so a newsroom, a contractor or a library can reuse the tables with a link back. Each page's sitemap date changes only when its content, its structured data or its links change, and a visible "page history" lists what changed on the page and when.

7. What we do not do

• No forms, no accounts, no newsletter and no lead generation. The only third-party script is Google Analytics, used to count visits and described in the privacy policy.
• No paid links, sponsored posts or paid traffic.
• No product reviews of equipment we have not tested; write-ups from specifications say so.
• No ranking promises, and no figure without a source and a date.
