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.

  1. Correction

    Tax tables refreshed: UK 2026/27, Canada 2026, Australia 2026–27, US standard deduction

    US: TY2025 standard deduction corrected to $15,750 single / $31,500 MFJ per the One Big Beautiful Bill Act (P.L. 119-21), which retroactively raised the Rev. Proc. 2024-40 figures. UK: rolled to 2026/27 — income tax bands and NI unchanged (frozen thresholds); student-loan plan thresholds updated (Plan 1 £26,900, Plan 2 £29,385, Plan 4 £33,795). Canada: rolled to 2026 — lowest federal rate now 14%, indexed brackets, BPA $16,452, CPP YMPE $74,600 / CPP2 to $85,000, EI 1.63% to $68,900; the Basic Personal Amount is now correctly modelled as a credit at the lowest rate rather than a deduction. Australia: rolled to 2026–27 — the 16% bracket cut to 15%, and HELP repayments now use the marginal system (15c/$ over $69,528, 17c/$ over $129,717, capped at 10% of income) replacing the old sliding scale. Super Guarantee references updated to 12%. All figures verified against IRS, GOV.UK, CRA, and ATO publications; worked examples across guides and narratives recomputed to match.

  2. Calculator update

    Eight new calculators added, plus a Family & Life section

    Added CAGR, biweekly mortgage, 50/30/20 budget, RRSP vs TFSA / Roth vs Traditional, Coast FIRE, savings-longevity (how long will my money last), dividend yield, and cost of raising a child — each with a worked-example guide. Every formula is documented on the methodology page and was verified numerically before launch.

  3. 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.

  4. 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.

  5. 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.

  6. 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.
