Find out when you'll have to start making repayments to your student loan and what happens if your income drops.

The threshold for repaying your student loan is an annual income of over $19,084 for the 1 April 2011 to 31 March 2012 tax year. This means that if you expect to earn more than this you'll need to start repaying your loan, even if you're still studying.

If you're going overseas your repayments will be different, depending on your loan balance.

Your repayments are worked out at 10 cents for every dollar of taxable income you earn above the threshold.

Taxable income includes things like salary, rental or investment income, and income from your own business. It doesn't include any working for families tax credits you may be getting, or your partner's income.

If your income drops

Don't worry if your income drops during the year - your employer will stop your repayments if your income falls under the threshold. If you're self-employed and think you're going to earn less than you earned last year, you may be able to reduce your repayments. Just tell us what you think you're going to earn on a Student loan interim repayment application estimation (SL3E) form - go to "Forms and guides". We'll then tell you what your new repayments are.
