What is the difference between Family Tax Benefit Part A and Part B, and can I get both?

They are two separate payments and most eligible families receive both. Part A is paid per child and is income-tested on your COMBINED family income — it starts reducing above $69,131. Part B is paid per family rather than per child, and is aimed at single parents and single-income couples: it is income-tested on the LOWER earner, who can earn $7,154 before it starts reducing, and no Part B is payable at all where the higher earner is above $124,327. So a couple on one modest income often receives both, a dual-income couple frequently receives Part A only, and the two are assessed independently. This calculator works out each one and shows them separately.

How is Family Tax Benefit Part A calculated?

FTB Part A is worked out per child based on the child's age and your combined family income. It's paid at the maximum rate while family income is $69,131 or less, then reduces by 20c in the dollar down to a base rate of $75.60 per child per fortnight. Above $123,078 that base rate reduces again by 30c in the dollar. This Family Tax Benefit calculator applies both income tests and pays whichever gives the higher result, the same way Services Australia does.

How much is FTB Part B and who can get it?

FTB Part B is up to $200.34 a fortnight where your youngest child is under 5, or $139.86 where they are 5 or older. It's aimed at single parents and single-income families. No Part B is payable if the higher earner's income is above $124,327, and couples stop receiving it once the youngest child turns 13. Single parents and carers keep it for longer.

Is this a Centrelink family income estimate calculator?

It uses the same family income estimate that Centrelink (Services Australia) applies to Family Tax Benefit, so it's a useful way to estimate your payments before you lodge. It's an independent estimate, not an official Centrelink figure — confirm your entitlement through myGov.

Is this FTB calculator up to date for Australia?

Yes. This Family Tax Benefit estimator uses the 2026–27 rates and thresholds that applied from 1 July 2026, sourced from Services Australia and the Family Assistance Guide. FTB rates are indexed every 1 July, and this calculator is refreshed each time they change.

Can I get FTB if my partner works?

Yes. FTB Part A is based on combined family income, so both incomes count. FTB Part B is different — it's income-tested on the lower earner, who can earn $7,154 a year before Part B starts reducing by 20c in the dollar. Enter the lower earner's income above for an accurate Part B estimate.

How do I apply for FTB?

Apply through your Centrelink online account on myGov. You'll need details about your family income, children and care arrangements.

What happens if I get paid too much FTB?

At tax time, Services Australia compares your estimated income to actual income. Overpayments must be repaid, either as a deduction from future payments or as a debt.

How much is Family Tax Benefit in 2026–27?

The maximum FTB Part A rate is $235.48 a fortnight for each child under 13 and $306.46 for each child aged 13 or over. You get the maximum rate while your combined family income is $69,131 or less, then it reduces by 20c in the dollar down to a base rate of $75.60 per child.

FTB Part B adds up to $200.34 a fortnight where your youngest child is under 5, or $139.86 where they are 5 or older. It is income-tested on the lower earner and stops entirely once the higher earner passes $124,327. Enter your details below for an estimate based on your own circumstances.

Part A income test applied: Your family income has reduced FTB Part A to the base rate, where it stays until the higher income threshold.

Part A supplement not included: The FTB Part A supplement is only paid where family income is $80,000 or less, so it is excluded from this estimate. The Part B supplement has no equivalent income limit — it sits inside the Part B rate and is reduced by the secondary earner test rather than cut off.

What this estimate assumes

Part B assumes one earner in the couple. Services Australia tests the lower earner's income separately, so entering it will usually lower the Part B figure.
Child support is not modelled. Where a child is from a past relationship, the Maintenance Action Test and the Maintenance Income Test can reduce Part A, in some cases to the base rate.
Part A assumes each child meets the immunisation and Healthy Start for School requirements.
Shared care is not modelled. Where care is shared, each carer gets a percentage of the rate shown rather than the whole amount.
Rent Assistance is not included. Families who rent privately can get more than this, and their income limits are higher.
The FTB energy supplement is not included. It is closed to new recipients and only continues for families who have had it since 19 September 2016.
Supplements are paid after the end of the financial year once payments are balanced, and only once required tax returns or non-lodgement advices are in.

Based on 2026-27 FTB rates and thresholds from Services Australia. Rates last checked 6 August 2026. This is an independent estimate, not an official Centrelink figure.

What families get at each income band

Every row below is the same family — a couple with two children aged 5 and 8, on a single income — so the only thing changing is the income test. The incomes are the thresholds themselves rather than round numbers, because that is where the answer changes. Figures are annual and come from the same calculator above.

Family income	Total a year	Part A	Part B
$69,131Lower income free area	$18,345	$14,220	$4,125
$80,000Part A supplement cut-off	$16,172	$12,047	$4,125
$101,539Into the 20c taper	$9,922	$5,797	$4,125
$123,078Higher income free area	$8,067	$3,942	$4,125
$136,218Cut-out point	$0	$0	$0

Lower income free area — The most you can earn and still get the maximum rate for each child.
Part A supplement cut-off — Above this the end-of-year Part A supplement is nil, though the fortnightly rate continues.
Into the 20c taper — Part A comes down by 20c for every dollar over the lower free area, until it reaches the base rate.
Higher income free area — Where the second test starts, taking 30c in the dollar off the base rate.
Cut-out point — Where Part A finally reaches nil. Part B has already stopped by here, at the primary earner limit.

Your own answer moves with the number of children, their ages and how the income is split between two earners, which is what the calculator is for.

What Is the Family Tax Benefit?

Family Tax Benefit (FTB) is a payment from the Australian Government to help families with the cost of raising children. It has two parts: FTB Part A is paid per child, and FTB Part B provides extra support for single parents and single-income families.

The amount you receive depends on your family income, the number and ages of your children and your family circumstances. Payments can be received fortnightly or as a lump sum at tax time.

FTB Part A vs FTB Part B

FTB Part A: Paid per child based on age. Higher rate for children under 13. Reduces once combined family income passes $69,131.
FTB Part B: Extra payment for single parents and single-income families, set by the youngest child's age. Couples stop receiving it once the youngest child turns 13.
Income test: Part A has two income tests: 20c in the dollar above $69,131 down to the base rate, then 30c above $123,078. Part B is tested on the lower earner.
Supplements: Both supplements are paid after balancing at tax time. The Part A supplement is only paid where family income is $80,000 or less; the Part B supplement has no equivalent limit and is instead reduced by the secondary earner income test.

Getting the Most from FTB

•Update your income estimate promptly to avoid overpayments or underpayments
•Single parents automatically qualify for FTB Part B at the full rate
•You can choose fortnightly payments or a lump sum at tax time
•Remember to confirm your immunisation status to maintain eligibility

About this calculator

This calculator exists to show you the arithmetic. It applies published Australian rates, thresholds and formulas to the numbers you enter and shows the working, so you can check it. That is all it does — it produces a number and describes what the number is. It does not recommend anything and it holds no opinion about any financial product.

What can move this result

It only knows the figures you type in. Offsets, deductions, prior-year losses, other income, your partner's position and anything you have not entered are not in the result, and any of them can move it a long way.
Rates and thresholds change, sometimes mid-year and occasionally with retrospective effect. Each calculator shows the financial year and the verification date it is working from — outside that year the result is wrong rather than approximate.
Assumptions are set to a reasonable default and every non-statutory one can be changed. Defaults are not predictions, and a small change to a growth or inflation assumption compounds into a large change in a long projection.
Where a result reaches two or more years into the future it is shown in today's dollars as well as future dollars, because a future-dollar figure overstates what the money will actually buy.
It is a generic calculator. It is not built around any particular product, it does not compare the market, and it cannot tell you whether a product is suitable for you.

This calculator is not intended to be relied on for the purposes of making a decision in relation to a financial product. Before you make a financial decision, consider obtaining advice from someone who holds an Australian Financial Services Licence. We do not, and we cannot advise you.
