How Income Estimates Affect Your CCS Rate and Balancing (2025-26)

How Income Estimates Affect CCS

Your family income estimate is the single biggest factor in determining your CCS percentage. Understanding how estimates work can help you plan your childcare budget more accurately.

Why Income Estimates Matter

CCS is income-tested. The higher your combined family income, the lower your subsidy percentage. Centrelink uses your estimated income throughout the year because they don't know your actual income until after you've lodged your tax return.

This means:

• An accurate estimate leads to more predictable payments
• An underestimate may result in a debt at balancing
• An overestimate may mean you miss out on subsidy you could have received during the year

How to Calculate Your Estimate

Your family income estimate includes all components of your Adjusted Taxable Income (ATI):

• Taxable income (wages, salary, business income)
• Reportable fringe benefits
• Investment income (dividends, rental income, interest)
• Foreign income
• Certain tax-free government payments

Both partners' income is included if you have a partner.

When to Update Your Estimate

Consider updating your estimate when:

• You or your partner start a new job or leave a job
• You receive a significant pay rise or bonus
• You're expecting investment income or capital gains
• Your partner's employment situation changes
• You receive unexpected lump sum payments

Key Takeaways

• Your income estimate directly affects your CCS percentage during the year — estimate your subsidy
• Both partners' income is included in the family income test
• Updating your estimate when circumstances change may help avoid large adjustments at balancing
• You can update your estimate through your Centrelink online account — see our guide on how to change your income estimate for timing tips

Frequently Asked Questions

How often can I update my income estimate?

You can update your estimate as often as needed throughout the year. There's no limit on updates.

What happens if I forget to update my estimate?

Your CCS will continue to be paid based on your old estimate. At balancing, your actual income will be compared to the estimate, which may result in a debt or top-up.

Does updating my estimate affect past payments?

No. Changes to your estimate only affect future payments. Past payments remain based on the estimate at the time.

Where do I update my income estimate?

You can update your estimate through your Centrelink online account via myGov, or by calling Centrelink.
