- 1
Cap weekly fees
Eligible_fees = min(weekly_ECE_fees, $300)
Fees above $300/wk don't increase the rebate.
- 2
Gross rebate
Gross_rebate = min(eligible_fees × 40%, $120)
40% rate set by FamilyBoost Amendment Act 2025.
- 3
Income abatement
If quarterly_income > $35,000: abatement = (excess) × $120 ÷ $22,286
Linear taper from $120 down to $0 between $35,000 and $57,286/quarter.
- 4
Net weekly rebate
Weekly_rebate = max(0, gross_rebate − abatement)
Quarterly claim = weekly × 13. Annual = weekly × 52.
Worked example
Inputs: Household $120k/yr, $280/wk ECE fees
Result: Quarterly income $30k (under $35k cap) → no abatement. Gross: min($280 × 40%, $120) = $112/wk. Annual: ~$5,824.
