Limitations and reproducibility

Manually curated; row-level sources provided: Rows were compiled by reading official summaries, bill reports, session laws and fiscal notes; no automated extraction pipeline. Each row carries its main source URL so it can be checked independently. Saved analyses are simple row counts that can be reproduced from the published CSV files.

  • Counts are a floor: small agency-set fees and some minor licensing-fee bills may be missing.
  • The unit is an individual change; splitting bills into changes involves judgment (a single rate schedule is one row; distinct taxes, fees, surcharges or newly taxed service categories are separate rows).
  • The debatable flag, who-pays grouping and cut packaging are editorial classifications.
  • Revenue estimates are copied as stated by each source for differing periods and are not comparable or summable.
  • Status reflects information available on 2026-10-11; the 2026 millionaires' income tax and the cuts tied to it depend on a pending court challenge and the I-645 repeal vote on November 3, 2026.
  • Some sources were read via text extraction rather than the original file.
  • A partisan caucus list was used as a starting checklist; all its items were verified against other sources, and several were corrected.
