Data updates & corrections

Tax tables and rates change; occasionally we get something wrong. This page logs every material update — dated, sourced, and permanent. Our correction policy is described in the editorial policy. No published corrections to date.

  1. Data update

    Bitcoin price snapshot + historical year-start prices added

    New bitcoin tools use documented Jan-1 historical prices (2011–2025) and a dated current-price snapshot refreshed live in-browser from CoinGecko. Source: CoinGecko historical data.

  2. Data update

    State income tax coverage expanded from 21 states to all 50 + DC

    30 new state tax tables added for 2025 (single filer). New states are marked unverified and their pages stay out of search indexes until each table is checked against the state revenue department's official publication.

  3. Calculator update

    Mortgage calculator upgraded to full PITI

    The mortgage calculator now models property tax, home insurance, HOA fees, and PMI in addition to principal & interest, matching how lenders quote total monthly housing cost.

  4. Data update

    All tax tables reviewed for tax year 2025 / 2025-26

    US federal brackets (IRS Rev. Proc. 2024-40), UK PAYE & NI (HMRC 2025/26), Canada federal brackets & CPP (CRA 2025), and Australia resident rates incl. Medicare levy (ATO 2025-26) verified against the official sources listed on the methodology page.
