Audits

Washington's millionaires tax can reach households where no one earns $1 million.

Version 3 (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

5 of 5 checks passed · version 1 · claude-haiku-5-5 · 22 October 2026

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 that households with no $1 million earner can owe the tax is supported by the couples, one-time income and stacking evidence items. The threshold claim of about half of inflation matches the section 316 evidence and the projection.

  2. Pass No obvious contradictions

    The finding True matches the answer and conclusion. The $821,000 figure, 9.9% deduction math ($9,900 on $1.1M) and $17,060 stacking figure are consistent across sections. The 0.57% figure in the half-percent response is not a glance-level contradiction and is noted in coverage.

  3. Pass Plausible justification

    The conclusion gives three concrete routes (shared deduction, AGI-based one-time income, capital gains add-back) plus the indexing rule and explains why the True rating follows from the statute.

  4. Pass Sources are relevant

    Bill report, session law, voters' pamphlet, RCW sections, amendment texts, Wallin tax-blog analyses, the Inlander DOR report and FactHub datasets are all on topic for the claims they support.

  5. Pass Common questions answered

    Five objections are present and each response addresses its question: the half-percent sentence, the No and Yes pamphlet rebuttals, the drafting error and home sales.

Coverage: Read only the article payload, key points, conclusion, evidence, objections, method and source takeaways. No source snapshots or web were consulted. No takeaway in the sources block is marked established: every takeaway, including the FactHub dataset takeaways, shows status 'not yet checked'. The key points labeled established therefore rest on unchecked takeaways, and I treated them as unchecked. Not flagged: the half-percent response says 0.57% of 2022 returns reported $1 million or more, but dataset fh-mix gives 21,530 such returns, about 0.68% of 3,168,080 households. 0.57% matches the 18,180 joint returns instead. This is left for the Source Checker or Standards reviewer. Arithmetic spot-checked: $9,900 couple tax, $17,060 stacking tax, $821,000 threshold, and the 0.66% and 0.79% household shares.
