Childcare Subsidy and Family Tax Benefit: How They Interact with Your Tax Return

Overview

Australian families can access two main government payments to help with the cost of raising children: the Child Care Subsidy (CCS) and Family Tax Benefit (FTB). Both are income-tested, and both require you to lodge your tax return for end-of-year reconciliation.

Getting these payments right — and understanding how they interact with your tax return — can mean thousands of dollars in your pocket or an unexpected debt to repay.

Child Care Subsidy (CCS)

CCS reduces the out-of-pocket cost of approved childcare (long day care, family day care, outside school hours care). It’s paid directly to your childcare provider, who passes the subsidy on as a fee reduction.

Income thresholds and subsidy rates for 2025-26

The income used is your family’s combined adjusted taxable income (ATI) — which includes taxable income, reportable fringe benefits, investment losses (added back) and certain other amounts.

Activity test and the 3 Day Guarantee

Since 5 January 2026, the old activity-linked sliding scale has been replaced by the 3 Day Guarantee: every family eligible for CCS gets access to a minimum of 72 subsidised hours per fortnight (three days a week), regardless of how many hours of work, study, or other recognised activity either parent does.

Higher access — up to 100 subsidised hours per fortnight — applies if:

• either parent has more than 48 hours per fortnight of recognised activity (paid work, study, volunteering, or looking for work), or
• the child is Aboriginal or Torres Strait Islander, or
• the family has an exemption, faces exceptional circumstances, or receives Additional Child Care Subsidy (child wellbeing, temporary financial hardship, or grandparent).

Family Tax Benefit (FTB)

FTB comes in two parts:

FTB Part A

A per-child payment based on the child’s age, paid to families with children under 20 (or 16–19 if in full-time secondary study). Once a child moves into full-time tertiary study or Australian Apprenticeship, FTB generally stops and they may instead claim a means-tested payment in their own name — see Youth Allowance income and assets tests explained (2025-26).

FTB Part A reduces once family income exceeds $69,131. It reduces by 20 cents per dollar above this threshold until it reaches the base rate of $1,971.00, then further reduces above a higher threshold ($123,078) by 30 cents per dollar. For the full 2026-27 rate schedule, see Family Tax Benefit rates for 2026-27.

FTB Part B

An additional per-family payment aimed at single-parent families or families where one parent earns under $7,154 per year.

For couples, FTB Part B is limited once the lower earner’s income exceeds $7,154, reducing by 20 cents per dollar. The primary earner’s income must be under $124,327 for the family to qualify. For a closer look at how the Part A and Part B income tests, free areas, and supplements work in detail, see Family Tax Benefit income tests and supplements (2026-27).

End-of-year reconciliation

This is where CCS and FTB interact directly with your tax return.

How it works

1. During the year, CCS and FTB are paid based on your estimated family income
2. After the financial year ends, you and your partner lodge your tax returns
3. Centrelink compares your actual income (from the ATO) against your estimates
4. If your actual income was lower than estimated → you receive a top-up payment
5. If your actual income was higher than estimated → you may have an overpayment debt to repay

FTB supplements

The supplements are only paid after reconciliation (i.e., after you lodge your return):

To receive the supplements, you must lodge your tax return (or notify Centrelink you don’t need to lodge) by the deadline — generally 30 June of the following year (i.e., by 30 June 2028 for the 2026-27 year). For the full detail on how and when each supplement is paid, see Family Tax Benefit supplements: how and when they’re paid (2026).

CCS withholding

Centrelink withholds 5% of your CCS payments during the year as a buffer against potential overpayments. This withheld amount is reconciled after you lodge your return. If you don’t owe a debt, the 5% is paid out to you as a lump sum.

Worked example

The Chen family — combined ATI of $120,000, two children (ages 3 and 6) in long day care 4 days per week.

CCS calculation:

• Income $120,000 → CCS rate approximately 83% ($85,279 base, 90% less 1% per $5,000 above that)
• Daily fee: $130 × 4 days = $520/week per child
• CCS per child: $520 × 83% = ~$432/week
• Family out-of-pocket: ~$177/week for both children
• Annual CCS received: ~$44,886

FTB Part A:

• Income above the $69,131 free area by $50,869 → reduction of $50,869 × 20% = $10,173.80
• Maximum Part A for 2 children (both under 12): 2 × $6,139.30 = $12,278.60
• $12,278.60 − $10,173.80 = $2,104.80, which is below the base-rate floor of 2 × $1,971.00 = $3,942.00, so Part A floors at ~$3,942 per year

FTB Part B:

• If one parent earns significantly less than the other, Part B may apply
• Youngest child under 5 → up to $5,223.15

At reconciliation: If their actual income was $115,000 (lower than the $120,000 estimate), they’ll receive a top-up. If actual income was $130,000, they’ll owe a debt on the excess CCS received.

Common traps

• Not lodging your tax return on time: You’ll lose the FTB supplements entirely if you miss the deadline. Both partners must lodge (or be formally exempt).
• Forgetting to update income estimates: If your income changes mid-year (new job, bonus, investment income), update your estimate with Centrelink to avoid a large year-end debt.
• Ignoring the ATI definition: Your adjusted taxable income includes items beyond taxable income. Reportable fringe benefits and salary-sacrificed super can push you into a lower CCS bracket.
• Not factoring in both parents’ income: CCS and FTB Part A use combined family income. FTB Part B uses the lower earner’s income separately.

Key takeaways

• CCS covers up to 90% of childcare fees for families earning up to $85,279, tapering to 0% above ~$535,000
• FTB Part A and B provide additional per-child and per-family payments based on income tests
• Both CCS and FTB are reconciled against your actual income after you lodge your tax return
• FTB supplements (up to $970.90 Part A and $478.15 Part B per child) are only paid after reconciliation
• Update your income estimate with Centrelink whenever your circumstances change to avoid debts
