Rules & Data Version

Rules version: 2025–26 Based on publicly available CCS settings as at 5 January 2026

CCSChecker provides an independent estimate only. Final Child Care Subsidy (CCS) eligibility, rates and payments are assessed and determined by Services Australia.

We endeavour to keep this tool as accurate as possible by aligning calculations with publicly available government guidance and updating rules when official settings change. However, this remains an estimation tool and individual outcomes may vary.

This page describes how CCSChecker implements publicly available rules. Rules and thresholds can change over time.

What CCSChecker Models

All calculations use full internal precision. Rounding is applied only at display level unless otherwise noted.

Core CCS Calculation Logic

1. CCS Percentage

For 2025–26:

Formula (standard rate):

Standard CCS % = 90% − ((ATI − 85,279) ÷ 5,000)

For a plain-English explanation of the percentage steps, see CCS percentage steps explained.

The result is then bounded between 0% and 90%.

2. Higher Rate for Additional Children Under 6

Where more than one CCS-eligible child aged 5 or under is in care:

The higher rate schedule for 2025–26:

Combined family income Higher rate
Up to $143,273 95%
$143,273–$188,273 Tapers from 95% to 80% (1 pp per $3,000)
$188,273–$267,563 80%
$267,563–$357,563 Tapers from 80% to 50% (1 pp per $3,000)
$357,563–$367,563 50%
Above $367,563 Standard rate applies (higher rate not available)

The higher rate is always at least equal to the standard rate — it never falls below it. Child ordering: the oldest CCS-eligible child aged 5 or under receives the standard rate first. Any additional under-6 children are then assigned the higher rate where eligible.

3. Activity Test → Subsidised Hours

Subsidised hours are calculated per child and are based on the partner with the lower recognised activity level.

For 2025–26:

The 72-hour minimum reflects the 3 Day Guarantee effective 5 January 2026. Every CCS-eligible family receives at least 72 subsidised hours per fortnight regardless of activity level. See our guide on activity hours explained for more detail.

Children identified as Aboriginal or Torres Strait Islander (ATSI) are modelled as receiving 100 hours per fortnight from 5 January 2026, subject to CCS eligibility requirements.

Weekly subsidised hours = fortnight entitlement ÷ 2.

For each child, subsidy is limited to the lesser of:

4. Hourly Fee Calculation

CCSChecker supports two fee models:

Daily fee model

Hourly fee model

5. Hourly Rate Caps

For 2025–26, the hourly caps are:

Service type Age band Hourly cap
Centre Based Day Care (CBDC) Under school age $14.63
Centre Based Day Care (CBDC) School age $12.81
Outside School Hours Care (OSHC) Under school age $14.63
Outside School Hours Care (OSHC) School age $12.81
Family Day Care (FDC) All ages $13.56
In Home Care (IHC) Per family $39.80

CCS is calculated using the lower of:

If your hourly fee exceeds the cap, the subsidy is calculated on the capped rate only. See hourly cap explained for a plain-English guide.

The difference remains out-of-pocket.

Display note: CCSChecker uses the exact published hourly caps in calculations. In some dashboard views a rounded cap may be shown for readability. Where a rounded cap is shown, calculations still use the exact cap value.

6. Withholding

Default withholding is 5% unless changed (0–10%).

Per subsidised hour:

Gross subsidy = capped hourly rate × CCS % Net subsidy = gross subsidy × (1 − withholding)

"CCS paid" is calculated using the net subsidy after withholding. For example, if withholding is 5%, CCSChecker models a 5% reduction in weekly payments to reflect the amount held back to reduce reconciliation risk.

Weekly out-of-pocket = total weekly fees − CCS paid.

Annual Calculations

Annual figures are calculated using 365-day modelling rather than a flat 52 weeks.

The 2025–26 financial year runs from:

1 July 2025 → 30 June 2026 (365 days)

Annual values use:

365 ÷ 7 = 52.142857 weeks

This means annual totals may differ slightly from simply multiplying a weekly figure by 52.

If a child turns 6 during the year, the year is segmented and weighted by the exact number of days before and after that date.

Year Impact Planner (Income Estimate Changes)

When you update your income estimate:

The Year Impact Planner:

  1. Calculates weekly outcomes under Scenario A and Scenario B.
  2. Splits the financial year at the relevant update date.
  3. Estimates:
    • Remainder-of-year impact
    • Full-year impact
    • Estimated balancing adjustment

Estimated balancing adjustment = (modelled full-year entitlement under your final scenario) − (modelled CCS paid based on when you updated your estimate).

This is a modelling estimate only.

PPL Planner

The PPL Planner models household income across the first year after a baby, covering parental leave and the transition to childcare.

2025–26 Paid Parental Leave Rates

Parameter 2025–26 value
Total entitlement 120 days (24 weeks)
Minimum reserved per parent 20 days (4 weeks)
Daily rate ~$189.62/day
Weekly rate ~$946/week
Income test (individual ATI) $350,000
Default tax withholding 15%

The daily rate is based on the 2025-26 National Minimum Wage (~$24.95/hr × 7.6 standard hours). It is indexed annually following the Fair Work Commission's minimum wage review.

Leave Income Calculation

For each parent:

The gap between total leave weeks and the childcare start date is modelled as an unpaid period (zero income from employment).

Monthly Income Timeline

The planner builds a 12-point monthly model covering:

  1. Govt PPL phase (month 1 through PPL exhaustion)
  2. Employer leave phase (overlapping or sequential with PPL)
  3. Unpaid leave phase (if any gap before return to work)
  4. Return-to-work phase (income resumes, childcare costs begin)

Each month carries a phase label, household income total, childcare cost, and net household position.

Return-to-Work Scenarios

The planner calculates four scenarios (2, 3, 4, and 5 days per week return):

For each scenario:

  1. Annual household income = parent 1 income (pro-rated to work days) + partner income
  2. Estimated CCS rate — derived from the combined income using the 2025–26 taper schedule
  3. Annual childcare cost (gross) = daily fee × care days per week × 52.142857 weeks
  4. Annual CSS benefit = gross childcare × cap-adjusted CCS rate
  5. Annual net after childcare = annual household income − (annual childcare cost − annual CSS benefit)
  6. Delta vs full-time = net at this scenario − net at 5 days/week

The CCS rate used in scenario modelling is estimated from the income taper only. The full CCS calculator (including hourly caps, actual hours used, and activity test) should be used for a more precise figure.

Family Tax Benefit (FTB) Estimator

The FTB estimator calculates estimated FTB Part A and Part B entitlements using 2025–26 rates. It is available as a standalone free tool at /ftb and as a premium feature within the dashboard.

FTB Part A

Paid per dependent child. The maximum fortnightly rate depends on the child's age:

FTB Part A reduces based on family Adjusted Taxable Income:

A base rate of $72.94 per child per fortnight applies until a second income threshold phases it out entirely.

An end-of-year supplement of $938.05 per child may apply for families with ATI up to $80,000.

For separated parents, child support (maintenance) received may further reduce FTB Part A under the maintenance income test.

FTB Part B

Paid per family (not per child) for single parents or couples where one partner earns below a threshold.

Maximum fortnightly rates depend on the youngest child's age:

An end-of-year supplement of $459.90 per family may also apply.

For couples:

FTB Part B is not payable to couples where both partners earn above the secondary earner cutoff ($34,438 for youngest under 5; $26,828 for youngest 5–13).

Income Assignment

The FTB calculator identifies the primary earner (higher income) and secondary earner (lower income) automatically. FTB Part B uses the secondary earner's individual income, not the combined family income.

When individual taxable incomes are provided in the earnings section, those values are used directly. If only combined ATI is available, it is split equally between partners.

Care Percentage

FTB entitlement depends on the percentage of care you have for each child:

Earnings Estimate — "What You Actually Keep" (Premium)

The earnings section estimates after-tax, after-childcare household income.

Tax Calculations

For each partner, the following are estimated separately:

Income tax uses 2025–26 individual tax brackets:

Medicare levy: 2% of taxable income (reduced for low-income earners between $26,000 and $32,500; nil below $26,000).

HELP/HECS repayments: Calculated on repayment income using 2025–26 thresholds. Repayment rates start at 1% at $54,436 and rise to 10% for income above $159,664.

Medicare Levy Surcharge (MLS): Applied for individuals/families above the MLS threshold without private health insurance.

For singles: 1% above $101,000; 1.25% above $118,000; 1.5% above $158,000.

For families: 1% above $202,000; 1.25% above $236,000; 1.5% above $316,000.

Net Earnings Calculation

Weekly take-home = (annual gross income − income tax − Medicare levy − HELP − MLS) ÷ 52.142857 − weekly childcare out-of-pocket

The "+1 day" modelling adds one childcare day and the corresponding income, then recalculates all taxes and CCS to show the net effect of an extra work day.

EV Novated Lease Impact (Premium)

An EV novated lease can affect CCS through reportable fringe benefits (RFBA).

How RFBA Affects ATI

Adjusted Taxable Income (ATI) includes:

When an EV novated lease generates an RFBA, the adjusted amount (RFBA × 0.51) is added to ATI for CCS and FTB purposes.

EV Lease RFBA Calculation

The reportable fringe benefits amount (RFBA) for an EV novated lease is estimated as follows:

  1. Taxable value = car value × 20% statutory rate × (days available ÷ 365) − employee contributions
  2. If taxable value falls below the $2,000 reporting threshold, RFBA is nil
  3. RFBA = taxable value × Type 2 gross-up rate (1.8868 for 2025–26)

The CCS-adjusted RFBA = RFBA × 0.51, which is added to family ATI.

What the Calculator Shows

The EV calculator estimates:

  1. The RFBA generated by the lease
  2. The adjusted RFBA amount added to ATI
  3. The resulting change to family ATI
  4. The effect on CCS percentage and weekly out-of-pocket
  5. The combined impact on HELP repayments and Medicare Levy Surcharge where applicable

Exempt EV novated leases (for eligible electric vehicles entered into from 1 July 2022) may produce a nil or reduced FBT liability but can still generate a reportable amount that affects ATI.

Even where FBT is exempt, a reportable fringe benefits amount (RFBA) may still arise and can affect ATI-based payments like CCS and FTB.
