COVID-19 - Level 1 If you've been affected by COVID-19, we may be able to help. Find out more

After the end of the tax year, around June/July, we’ll send you an income tax assessment and ask you to check the information we have about your income and family. If the information is right, you don’t need to do anything. If your income or other family details are incorrect, you need to let us know.


There are some income types that are not on your income tax assessment that we may need to know about to calculate your Working for Families entitlement. You may need to complete the Adjust  your income form -  IR215.

Adjusting your income for Working for Families and student loans

Weekly or fortnightly payments

Your weekly or fortnightly payments during the year are based on an estimate of what you will earn. At the end of the year we work out your entitlement based on what you actually earned. If we paid you too much, we’ll send you a notice of assessment showing you the amount to pay. If we didn’t pay you enough, we will send a notice of assessment showing you the amount we will refund to your bank account.

End of year lump sum payment

If you chose to wait and get Working for Families paid as a lump sum, we’ll work out your entitlement based on your income for the tax year just ended. This will be calculated when we finalise your income tax assessment. We’ll then send you a notice of assessment showing you the amount we will refund into your bank account.

Refunds and debt

We pay refunds after we process income tax assessments.  Any tax or Working for Families you owe should be paid by 7 February. If you have a tax agent, you'll need to pay by 7 April. We’ll send you a reminder letter before your payment is due. If you haven’t paid your bill in full by the due date, penalties and interest may apply.

We’ve got options on how to repay overpayments to suit your circumstances, including:

Using future Working for Families payments to repay overpayments

Some customers prefer that we take any money they owe from their future Working for Families payments. Contact us to work out how much you would like to repay, and we’ll set this up for you.

Setting up a payment plan

Payment plans can make things easier by splitting what you owe over weekly or fortnightly repayments. This could be an automatic payment or a deduction from your income. We’ll work with you to ensure any repayments are at an amount you can afford.

Online instalment arrangement

You can propose a payment plan that works for you using our online instalment arrangement tool. Or drop us a web message letting us know your current situation, and how we can help. If paying money back just isn’t possible right now, we’ll work with you to come up with a solution.
