2026–27 rates Part A and Part B together

Family Tax Benefit Calculator (2026–27)

Most calculators do Part A or Part B. This one does both at once, using your children, your combined income and the lower earner’s income — and then shows you the two income tests line by line.

Where each payment stops

Part A does not stop at the higher income free area — it keeps reducing by 30 cents for every extra dollar until the payment runs out. With more children the cut off moves out, because the maximum rate is higher:

FamilyMaximum Part A a yearPart A stops above
1 child under 13$6,139$129,648
2 children under 13$12,279$136,218
3 children under 13$18,418$148,506
4 children under 13$24,557$168,971
5 children under 13$30,697$189,435

Part B is far narrower. A couple with a youngest child under 5 loses Part B entirely once the lower earner passes about $35,661, and for a youngest child aged 5 to 12 it runs out around $27,777.

The three numbers that decide your payment

  1. How many children, and how old. Part A is paid per child, at a higher rate once a child turns 13.
  2. Your combined family income. This drives Part A. Above $69,131 it falls by 20c per dollar, and above $123,078 by 30c per dollar.
  3. The lower earner’s income. This drives Part B. Above $7,154 it falls by 20c per dollar, and the higher earner must stay under $124,327 for the family to get Part B at all.

A common surprise: a pay rise for the lower earner cuts Part B, while a pay rise for the higher earner cuts Part A — and may remove Part B entirely once they pass $124,327. Changing who earns what can matter as much as how much you earn between you.

Frequently asked questions

Do I get Family Tax Benefit Part A and Part B?

They are two separate payments with separate income tests. Part A is per child and is tested on your combined family income. Part B is per family, aimed at single income families, and is tested on the lower earner’s income (or, for a single parent, on the primary earner limit). Many families get both.

What is the Family Tax Benefit income cut off?

For Part A it depends on how many children you have — see the table below. A one child family stops getting Part A at about $129,648. Part B stops earlier: for a couple whose youngest child is under 5, it runs out when the lower earner’s income reaches about $35,661.

How much is FTB Part A per fortnight?

The maximum for a child under 13 is $235.48 a fortnight, and for a child aged 13 to 15 it is $306.46. Those maximums are then reduced by the income test. The calculator above converts the yearly rates for you.

What are the Family Tax Benefit supplements?

The Part A supplement is up to $970.90 per child and the Part B supplement is up to $478.15 per family. They are paid after the end of the income year, once you and your partner have lodged your tax returns. The Part A supplement is not paid at all if your family income is more than $80,000.

Why does my payment change when my income goes just over $80,000?

Because the Part A supplement is only included in your rate when family income is $80,000 or less. Cross that line by one dollar and the supplement disappears for every child — a cliff, not a taper. It is one of the sharpest edges in the family assistance system.

Who counts as the primary earner for Part B?

The higher earner of the two of you. They must earn no more than $124,327 a year for the family to get Part B at all. It does not matter who is the main carer — the income test follows the money, not the caring.

How is the payment paid?

You can take it fortnightly through Centrelink, as a lump sum after you lodge your tax return, or a mix of both. The yearly figures here are the same either way — only the timing changes.

How up to date are these figures?

They are the 2026–27 rates, which apply from 1 July 2026. Family assistance rates are indexed by CPI each 1 July, so use the calculator or check the source link below before relying on a number.
