How NZ FamilyBoost rebate is calculated

40% of your licensed ECE fees, capped at $120/week. Abates above $35,000/quarter household income, cuts to $0 at $57,286/quarter (~$229,144/yr).

  1. 1

    Cap weekly fees

    Eligible_fees = min(weekly_ECE_fees, $300)

    Fees above $300/wk don't increase the rebate.

  2. 2

    Gross rebate

    Gross_rebate = min(eligible_fees × 40%, $120)

    40% rate set by FamilyBoost Amendment Act 2025.

  3. 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. 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.

Frequently Asked Questions

How does FamilyBoost work in 2026?
FamilyBoost is a quarterly tax rebate from IRD that refunds 40% of your licensed ECE (early childhood education) fees, up to $120 per week. You pay the ECE provider as normal, then claim the rebate through myIR every three months. The rebate is paid for children under 6 attending licensed ECE (kindergarten, daycare, kohanga reo, home-based care). The household income cap is $229,144/year ($57,286/quarter) — above that you get nothing. Source: IRD — FamilyBoost.
What changed with FamilyBoost in 2025-26?
The Income Tax (FamilyBoost) Amendment Act 2025 made three big changes: (1) the rebate proportion rose from 25% to 40% of ECE fees; (2) the maximum weekly rebate doubled from $75 to $120; (3) the income cap rose from $180,000 to $229,144/year. NZ Herald reported that some families were under-claiming because they used the old calculator — always check IRD’s current calculator. Source: IRD media release, NZ Herald.
Can I claim FamilyBoost AND Working for Families or Best Start?
Yes — FamilyBoost is separate from Working for Families (FTC, IWTC, MFTC) and Best Start. They don’t reduce each other. The only requirement is that your child must attend a licensed ECE service for FamilyBoost to apply, and you must have paid the fees yourself (not had them covered 100% by the 20-Hours ECE subsidy or WINZ Childcare Subsidy). Whatever you paid out of pocket is eligible. Source: IRD — FamilyBoost FAQs.
How do I actually claim my FamilyBoost rebate?
Register for myIR if you don’t already have an account, then add the FamilyBoost service. Each quarter (Jan-Mar, Apr-Jun, Jul-Sep, Oct-Dec) you upload invoices/receipts from your ECE provider showing what you paid. IRD calculates the 40% rebate against the $120/wk cap, applies the income abatement, and pays the lump sum into your nominated bank account. Claims close 3 months after quarter end (e.g. Q1 Jan-Mar must be claimed by 30 June). Source: IRD — FamilyBoost.
