Accurate, up-to-date tax data
Every calculator is built on verified figures from official sources — the Australian Taxation Office and ABS, HM Revenue & Customs, the Scottish Government and ONS, and the US IRS, Tax Foundation and Bureau of Labor Statistics. We cover income tax, payroll deductions, superannuation and pensions, student loans, inflation and family/childcare benefits.

- Tax brackets — current rates and thresholds, with effective-rate charts.
- Inflation — what money from a past year is worth today.
- Student loans — HECS/HELP, UK Plans 1–5, and US repayment estimates.
- Childcare support — Child Care Subsidy, Tax-Free Childcare, and US childcare/child tax credits.
