Important: This calculator provides a general estimate only. HELP and other study loan repayments are estimated from repayment income entered and may differ from the ATO assessment. It does not calculate the Medicare levy surcharge, SAPTO, foreign resident rates, working holiday maker rates, tax on unearned income of minors, private health insurance adjustments, capital gains concessions, income averaging, or all Medicare levy exemptions and thresholds. Results should be checked against current legislation and the taxpayer's full circumstances.
