Audits

Washington's millionaires-tax estimate assumes no response; studies show high earners respond.

Version 2 (draft). FactHub's auditors are automated reviewers, separate from the process that writes articles. Each checks a fixed, published list of things and grades the results with its own published rule. They can be wrong; an audit is not a human expert review. All auditors

First Look

A: Passes the first look: nothing obviously wrong. Minor notes may be reported as feedback without lowering the grade.

5 checks
  1. Pass Title matches the evidence

    The title says the estimate assumes no response and that studies show high earners respond; the fiscal note's 'do not reduce taxable income' line and the Rauh and Shyu erosion figures support both halves.

  2. Pass No obvious contradictions

    Finding True matches the answer and conclusion, and the 12-of-18, 4-recession-shortfall, and $12.9B figures agree across sections.

  3. Pass Plausible justification

    The conclusion explains that both halves of the claim rest on primary documents and a peer-reviewed study, and that the erosion-to-shortfall step is unsupported, which follows from the evidence.

  4. Pass Sources are relevant

    Each source's name, title and description fits the claim it supports: fiscal notes, the Rauh and Shyu study, Multnomah and New Jersey migration studies, JCT and Montana practice documents, and official collection reports.

  5. Pass Common questions answered

    Six objections are present, and each response directly answers its own question.

Coverage: I read the full article text, the keyPoints, evidence items, objections, conclusion, method, the datasets and the source takeaway blocks. I did not read source snapshots or the web. Every takeaway in the sources block is marked 'not yet checked', and no takeaway is marked established; the figures that depend on them (for example the 45.2/60.9 erosion, the Multnomah 8.5%, the $1.3B Tufts figure, and all 18 ratio comparisons) are unchecked here and left to the Source Checker. The only key points marked established are the fiscal-note and I-645 items and the Rauh and Shyu erosion item. One arithmetic point is flagged for the Source Checker and not raised as a finding: the conclusion and dataset give 0.84 for Washington capital gains in 2023-24 against the $527M gross estimate, but the cited 2023 ($394.7M) and 2024 ($583.8M) figures average to about 0.93, so the 0.84 may come from a different basis that the article does not state. I did not verify the $112M Multnomah forecast or the Maryland, LAO and Massachusetts forecast values, which are not stated in the article text beyond the source takeaways.
