  • Interest and penalties

    Australia’s revenue system relies on taxpayers providing correct information to establish their tax liability and paying the correct amount of tax on time.

    We apply interest on late payments, unpaid tax debts, and outstanding amounts. Penalties apply when a tax obligation is not met. If you pay early, overpay or there is a delay in a refund we owe you, we also pay interest.
