Two emotions rushed through Aleks' body when she logged into her MyGov account and saw a bill for $15,000 on the screen - worry, followed pretty quickly by anxiety.
At first when she saw the huge number she felt sick. Had she done something wrong? The next question that popped into her head, however, was worse.
How am I supposed to pay this money back?
Thousands of Australian families have been hit with bills from the Federal Government demanding they repay childcare subsidies with their deadline only weeks away.
Watch: The Family Tax Benefit and Child Care Subsidy explained. Post continues after video.
The childcare subsidy is paid based on an estimate of your income but if your actual income is more, the government asks to be repaid.
For example, if your combined income is $120,000, you receive a rebate of between 68-69 per cent. If you're in the $140,000 bracket, that percentage changes to between 56-60 percent. An income of $170,000 will see your rebate drop to 51-52 per cent.
The thing is, it's quite easy to underestimate, especially if your circumstances change during the year; if you get bonuses, if you get payments you can't 'estimate' beforehand, or you work as a freelancer and set your salary as you go.
