Should I Work an Extra Day? Childcare, Tax & CCS Check
Before you add another work day, do not compare your daily pay with the childcare fee.
That is the calculation that catches families out.
The useful calculation is:
extra pay minus tax minus extra childcare gap fee minus any CCS change minus any FTB change = what your family actually keeps
For some families, the extra day is absolutely worth it.
For others, the gain is much smaller than expected.
Check what your family actually keeps
The 5-minute extra day check
1. What will you earn after tax?
Gross pay is not the number you keep.
Use after-tax income as the starting point.
2. Will the extra work day need an extra childcare day?
If yes, use the childcare gap fee, not the centre's full daily fee.
3. Does the extra care fit inside your subsidised hours?
Eligible families generally get at least 72 hours per fortnight from 5 January 2026. Some families may get 100 hours depending on recognised participation, exemptions or child-specific rules.
If the extra day pushes you above your subsidised hours, the cost can jump.
4. Will your annual income estimate rise?
Your CCS percentage is affected by your family income estimate. Services Australia uses your family income estimate for family assistance payments including CCS and FTB.
5. Could FTB change too?
If your family receives FTB, more income can affect that estimate as well.
6. What do you actually keep?
This is the number that matters.
Not gross pay.
Not the childcare fee.
The household result.
Why the extra day decision is tricky
Adding a day can change more than one thing at once.
| What changes | Why it matters |
|---|---|
| Work income | More gross income, but not all take-home. |
| Tax | Extra income may be taxed at your marginal rate. |
| Childcare | More care usually means more gap fees. |
| CCS | Higher income or extra hours can change the result. |
| FTB | Family payments may reduce as income rises. |
| Balancing | A wrong estimate can catch up later. |
This is why "I earn $400 and childcare is $150, so I'm $250 ahead" is usually too simple.
A better question
Do not ask:
"Can we afford another childcare day?"
Ask:
"If I work one extra day and add one extra day of care, what does our household keep over the year?"
That is the premium question.

Frequently Asked Questions
Is it worth working an extra day after childcare?
It depends on your after-tax income, extra childcare gap fee, CCS percentage, FTB position, subsidised hours and session length.
Can earning more reduce CCS?
Yes, it can. Your CCS percentage is affected by your family income estimate.
Does working more always mean more subsidised hours?
Not always. Eligible families generally receive at least 72 hours per fortnight. Some families may receive 100 hours depending on recognised participation, exemptions or child-specific rules.
What is the best way to compare work days?
Compare the full household result after tax, childcare, CCS and FTB. That is what Premium is designed to help with.
