Australian Income Tax Calculator review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Australian Income Tax Calculator is a free web tool on Moneysmart for Australian residents who want an estimate of income tax, Medicare levy and take-home income. It can also provide a marginal tax rate and a tax-return estimate. Users enter employment income after salary sacrifice and before tax, along with other taxable income, then choose an income frequency and financial year. Results include taxable income, income tax, Medicare levy and after-tax income.

The calculator focuses on federal Australian income estimates rather than broader tax planning. It covers employment income and other taxable income, and lets users select how frequently income is received and which financial year to estimate. That makes it suited to checking how income tax and the Medicare levy affect take-home pay, or forming a preliminary tax-return estimate. It does not present itself as a tool for other jurisdictions or for calculating a complete tax position.

Its boundaries matter when comparing an estimate with a final tax outcome: the calculator excludes rebates and offsets and does not include the Medicare Levy Surcharge. Choose it for a quick estimate of Australian resident income tax, marginal rate and after-tax income using the available inputs. It is less suitable if the calculation needs to account for tax rebates, offsets, the surcharge, or tax situations beyond the income sources it accepts; in those cases, a broader tax tool or professional advice may be a better fit.
