Rate Update
NSW stamp duty brackets updated (CPI indexed)
NSW Revenue updated all transfer duty bracket thresholds from 1 July 2025 per CPI indexation. New thresholds: $17,000 / $37,000 / $99,000 / $372,000 / $1,240,000 / $3,721,000 (premium). Our NSW stamp duty and first home buyer calculators now reflect these rates.
Rate Update
NSW foreign buyer surcharge increased to 9%
The NSW surcharge purchaser duty increased from 8% to 9% effective 1 January 2025. Our Stamp Duty Calculator has been updated for NSW foreign buyer purchases.
Rate Update
Medicare Levy Surcharge thresholds updated
MLS thresholds indexed for 2025-26. Single: $101,001 / $118,001 / $144,001. Family: $202,001 / $236,001 / $288,001 (plus $1,500 per dependent child after the first). Family uplift now properly reflected in the UI.

Added explicit sections on GDPR (European users) and CCPA (California residents) rights. Also added Children's Privacy section and offline data disclosure for the mobile app.
New Calculator
Four new calculators added
Tax Return Estimator (with 6 deduction categories and refund estimate), PAYG Withholding Calculator, ABN Lookup Tool (validates ABN format and has no-ABN withholding helper), and BAS Calculator (GST on sales/purchases, PAYG instalment and withholding).
Rate Update
Victoria land tax brackets updated
Updated VIC land tax brackets to current SRO Victoria rates (2024-2033 COVID debt repayment plan rates included in base amounts). Fixed bracket values for $300K-$600K, $600K-$1M, $1M-$1.8M, $1.8M-$3M, and over $3M.
Per ATO rules, employer Super Guarantee should be calculated on the full ordinary time earnings, not the reduced salary after sacrifice. Fixed — the calculator now correctly shows that salary sacrifice does not reduce your SG entitlement.
Fix
Centrelink assets test now uses tapering
Services Australia applies a $3 per fortnight reduction for every $1,000 above the lower assets threshold, not a pass/fail cutoff. Our Centrelink Calculator now correctly tapers payments between lower and upper thresholds and shows partial payment amounts.
Fix
Super Contribution excess tax calculation fixed
Excess concessional contributions are now taxed at your marginal rate with a 15% offset for tax already paid by the fund (per ATO rules), instead of a flat 47% rate.
Fix
First Home Buyer stamp duty calculation improved
Replaced the rough 4% estimate with the actual bracket-based stamp duty calculation for all states, with proper FHB exemption and linear concession interpolation between exempt and concession thresholds.
Rate Update
Centrelink payment rates indexed (March 2026)
Updated JobSeeker, Age Pension, Parenting Payment, and Rent Assistance rates per Services Australia indexation on 20 March 2026. Single JobSeeker: $795.20/fn. Single Age Pension: $1,200.90/fn (includes supplements).
