Family Tax Benefit Calculator: Estimate Your Entitlements for 2025-26

Raising a family in Australia comes with significant costs, but the Family Tax Benefit (FTB) is designed to help ease the financial burden. Whether you're a single parent working part-time or a dual-income household with multiple children, understanding how FTB works can make a real difference to your family budget. This guide explains how to estimate your entitlements for the 2025-26 financial year and what factors influence your payment amounts.

What Is the Family Tax Benefit?

The Family Tax Benefit is a government payment that helps families with the cost of raising children. It's administered by Services Australia and paid in two parts: Part A and Part B. Unlike some other Centrelink payments, FTB is not a loan and doesn't need to be repaid — it's genuine financial support to help with everyday expenses like food, clothing, education, and childcare.

The amount you receive depends on several factors including your family's combined income, the number of children you have, their ages, and your household structure (single parent vs partnered). Payments can be made fortnightly to help with regular budgeting, or as a lump sum at the end of the financial year if you prefer. Many families choose the fortnightly option to help with ongoing expenses, while others use the lump sum as a way to boost their tax refund or cover larger annual costs like school fees.

Understanding Family Tax Benefit Part A

Part A is the primary component of FTB and is paid per child based on your family's income and the child's age. For the 2025-26 financial year, the maximum rates vary depending on how old your children are. Younger children typically attract higher payments, recognising that early childhood often comes with greater expenses including childcare, nappies, and specialised nutrition.

The income test for Part A works on a sliding scale. Families with an adjusted taxable income below approximately $63,151 (as of 2025-26) receive the maximum rate. Above this threshold, your payment gradually reduces by 20 cents for every dollar earned until it reaches zero. There's also a higher income free area for families with more children — for each child after your first, this threshold increases by approximately $3,548. This recognises that larger families face proportionally higher living costs and ensures they retain support for longer as their income rises.

Importantly, Part A includes additional supplements that may be payable at the end of the financial year. The FTB Part A supplement (up to $879.65 per child for 2025-26) is an annual payment that helps with unexpected expenses and is typically paid after you lodge your tax return or confirm your income with Services Australia. To receive this supplement, you must meet immunisation requirements and have a Health Care Card or be registered for Medicare.

How Family Tax Benefit Part B Works

Part B provides extra assistance for single parents and families where one parent earns little or no income — typically stay-at-home parents or those working very limited hours. This recognises that when one parent is primarily responsible for caring for children, the family's earning capacity is reduced and additional support is warranted.

For single parents, Part B is available until your youngest child turns 16 (or 18 if they're studying). For couple families, Part B is generally only available until your youngest child turns 13. The payment rate depends on the age of your youngest child — higher rates apply for children under 5 years old, reflecting the intensity of care required during early childhood. For 2025-26, single parents can receive up to approximately $188.70 per fortnight if their youngest child is under 5, or $131.00 per fortnight if their youngest is aged 5-18.

The income test for Part B is stricter than Part A. For partnered families, the primary earner's income must be $110,000 or less. For single parents, there's also an income threshold that limits eligibility. Like Part A, there's an annual supplement of up to $424.15 for 2025-26, paid after the financial year ends once your income is confirmed. This supplement can make a meaningful difference to your annual budget, especially if you're managing on a tight income.

FTB Payment Rates Summary for 2025-26

The following table outlines the approximate maximum fortnightly rates for Family Tax Benefit Part A and Part B. These figures represent the highest possible payment rates — your actual entitlement may be lower depending on your family's income and circumstances.

How Income Affects Your FTB Payments

The Family Tax Benefit is income-tested, which means your family's earnings directly impact how much you receive. For Part A, the income test looks at your family's combined adjusted taxable income. The free area (where you receive the maximum rate) is approximately $63,151 for families with one child, increasing by roughly $3,548 for each additional child. This means a family with three children could earn up to around $70,247 and still receive the maximum Part A rate.

Once your income exceeds the free area, your Part A payment reduces by 20 cents for every dollar earned. This taper rate is relatively gentle compared to some other Centrelink payments, meaning you don't lose your entire entitlement as soon as you cross a threshold. However, at higher income levels, the payment does eventually phase out to zero. Understanding where your family sits on this scale helps you budget accurately and avoid surprises at tax time.

For Part B, the income test is different. In couple families, it primarily looks at the lower earner's income, with the primary earner's income capped at $110,000. For single parents, there's a separate income threshold. If you're unsure how your specific income situation affects your entitlements, it's worth using a calculator or speaking with Services Australia directly. Accurate income estimation throughout the year is crucial — if you underestimate your income, you may receive overpayments that need to be repaid later.

Maximising Your Family's Financial Support

To get the most from the Family Tax Benefit system, there are several strategies worth considering. First, ensure you've accurately reported your income to Services Australia. If your circumstances change during the year — you get a pay rise, change jobs, or your partner starts working — update your income estimate promptly to avoid overpayments. Overpayments can result in debts that need to be repaid, often through reductions in future payments or your tax refund.

Second, don't forget about the annual supplements. Many families miss out on these because they haven't met the immunisation requirements or haven't lodged their tax returns. The supplements can add up to over $1,300 per child annually, so they're well worth claiming. Make sure your children's immunisations are up to date according to the National Immunisation Program Schedule, and lodge your tax return promptly after the financial year ends.

Finally, consider how FTB interacts with your broader financial situation. If you're returning to work after parental leave, your increased income will affect your FTB, but you may also become eligible for other benefits like the Child Care Subsidy. Understanding your complete financial picture — including your take-home pay, income tax obligations, and any superannuation contributions — helps you make informed decisions about work and family.

FTB and Your Tax Return

Family Tax Benefit interacts with the tax system in important ways. While FTB itself is not taxable income (you don't pay tax on it), your eligibility and payment rates are based on your taxable income. This means there's a reconciliation process at the end of each financial year where Services Australia compares the income estimate you provided against your actual taxable income as reported to the ATO.

If you earned more than you estimated, you may have been overpaid FTB and will need to repay the excess. If you earned less, you may be entitled to a top-up payment. This reconciliation happens automatically once you (and your partner, if applicable) lodge your tax returns. To avoid surprises, it's wise to review your income estimate regularly and update it if your circumstances change. If you have a HECS-HELP debt or make salary sacrifice arrangements, these can affect your adjusted taxable income used for FTB calculations, so factor these into your estimates.
