A mum in Coffs Harbour got a letter from Centrelink in September asking for money back. She had been getting Family Tax Benefit all year, based on an income estimate she gave right at the start. Her real income came in higher than expected, thanks to some extra shifts over summer. That gap between the estimate and the real number turned into a debt. Stories like this are common. Understanding how Family Tax Benefit, often shortened to FTB, actually works can save you from the same surprise.
Here is the short version. FTB is a Centrelink payment for families raising children. It comes in two parts, called Part A and Part B. How much you get depends on your income, your family situation, and the ages of your kids at the time.
Getting the estimate right matters more than most people realise. If your tax situation is anything but simple, having a tax agent help you lodge on time and accurately makes the whole reconciliation process far less stressful for everyone involved.
What is Family Tax Benefit
FTB is a payment from Services Australia to help with the cost of raising children. Even so, it sits separate from tax itself, though the amount you get depends heavily on your taxable income. Families can receive FTB fortnightly, or as a lump sum after the end of the financial year.
Family Tax Benefit Part A versus Part B
Part A gets paid per child. It scales with your family income and how many children you have. Part B works differently again. It suits single parents and families with one main income earner, and it uses a separate income test altogether. Because of this, some families qualify for both parts. Meanwhile, others only qualify for one.
Does Family Tax Benefit count as taxable income
No. FTB itself does not count as taxable income, so you do not need to declare it on your tax return. That said, everything else you earn feeds into the taxable income figure that determines how much FTB you get. As a result, this is exactly where a lot of confusion starts.
Why the tax and Centrelink systems feel tangled together
FTB and your tax return sit in two different systems, run by two different agencies. Even so, they depend on each other more than most people expect. First, Centrelink estimates your FTB during the year using the income figure you provide. Then the ATO confirms your actual income once you lodge. Since one relies on the other, a delay or a mistake in either system can throw the whole thing out.
Why you might get a Family Tax Benefit debt at tax time
FTB gets estimated during the year, then reconciled once your actual income is known. Say you end up earning more than your estimate. In that case, Centrelink may have paid you more than you were entitled to, and it will ask for the difference back. On the other hand, earning less than expected can mean you were actually owed more all along.
This reconciliation only happens properly once your tax return gets lodged. Until then, Centrelink has no way to confirm your real income for the year. Delaying your return, even by a few months, delays this process too, and leaves any debt sitting there longer than it needs to.
How lodging on time helps
Lodging your tax return promptly gets your real income figure to Centrelink sooner. As a result, any reconciliation, whether it works in your favour or not, gets sorted out faster. A family in the Hunter Valley found this out after putting off their return for over a year. Their FTB reconciliation sat unresolved the entire time, and the eventual debt felt far bigger than it would have if it had been sorted the year it happened.
What happens if you underestimate your income on purpose
Some people assume a lower estimate means bigger fortnightly payments with no downside. It does not work that way. Centrelink checks your estimate against your lodged tax return every single year without fail. Underestimating on purpose simply delays the moment you find out, rather than avoiding it altogether. Meanwhile, the gap between what you were paid and what you were owed keeps building until reconciliation catches up with you.
Getting your estimate right during the year
If your income changes during the year, whether from extra shifts, a new job, or a change in hours, update your estimate with Centrelink as soon as you reasonably can. After all, waiting until tax time to find out you were overpaid rarely feels good. For families with irregular income, such as anyone running a small business or working variable hours, checking in more often than the bare minimum is always worth the effort.
Self employed parents and FTB estimates
Self employed income is naturally harder to estimate than a steady wage. Understandably, profit can swing a fair bit from one quarter to the next, especially in a seasonal business. Because of this, self employed parents are often the ones most caught out by a big reconciliation gap. Reviewing your estimate partway through the year, rather than waiting for a set and forget approach, helps keep the eventual surprise smaller.
Since FTB and your tax return are so closely linked, getting your tax return done properly and on time is one of the simplest ways to avoid a nasty reconciliation surprise. If your income has changed this year, or your family situation is more complicated than a standard payslip, get in touch and we will make sure your return reflects it accurately. You can also check how taxable income is calculated through the ATO website, since that figure is what Centrelink relies on for FTB.
Frequently asked questions
What is the difference between Family Tax Benefit Part A and Part B
Part A gets paid per child, based on family income and the number of children. Part B suits single parents and one income families, using a separate income test. Some families receive both, depending on their situation.
Is Family Tax Benefit taxable income
No. FTB payments themselves are not taxable and do not need to be declared as income. Even so, your other taxable income is exactly what determines how much FTB you receive.
Why did I get a Family Tax Benefit debt
This usually happens when your actual income for the year comes in higher than the estimate you gave Centrelink. Once your tax return confirms your real income, any overpayment gets reconciled as a debt.
Can my FTB change if my income changes during the year
Yes. Updating your income estimate with Centrelink as your circumstances change helps avoid a large gap between what you were paid and what you were actually entitled to.
Do I need to lodge a tax return to keep getting Family Tax Benefit
Generally, yes. Centrelink needs your confirmed income to finalise your FTB for the year, and that relies on your tax return being lodged. Delaying your return can delay or complicate your payments.
Does a partner’s income affect FTB
Yes, in most cases. FTB generally looks at combined family income rather than just your own. As a result, a partner starting a new job or increasing their hours can shift your entitlement, even if your own income stays exactly the same.
What happens if I stop being eligible partway through the year
Report the change to Centrelink as soon as it happens, rather than waiting around for reconciliation to catch it. Otherwise, you risk a larger debt building up between the point your circumstances changed and the point your tax return eventually confirms it.
Can I get FTB as a lump sum instead of fortnightly
Yes. Some families choose to receive FTB as a lump sum after the end of the financial year, once their actual income is confirmed, rather than fortnightly instalments throughout the year. This avoids the reconciliation surprise entirely, since the payment is based on a known figure rather than an estimate. The trade off is not having regular payments to help with day to day costs along the way.
Does FTB affect my tax refund
Not directly. FTB and your income tax refund are calculated separately. That said, if you owe a Family Tax Benefit debt, Centrelink can sometimes recover it by withholding part of a future tax refund, so the two are not entirely unconnected in practice. Either way, sorting out both at once tends to be less stressful than dealing with them separately.
What income counts towards the FTB estimate
Centrelink generally looks at your total taxable income, plus a few other amounts such as certain fringe benefits and foreign income. Because of this, a pay rise, a bonus, or extra freelance work can all shift your estimate, even if none of it feels like a big change on its own. Keeping Centrelink updated as these things happen, rather than only thinking about it at tax time, keeps the eventual reconciliation much smaller.
