Unlike marginal tax rates, the repayment rate applies on the full HRI, so that a person with a HRI below $45,881 in 2019/20 will not need to make a compulsory HELP repayment, but a person with a HRI of $80,000 would make a payment of $4,400. This is 5.5% of the HRI (not taxable income or the debt balance) of $80,000. The compulsory repayment amount cannot exceed the balance of the HELP debt.
