Is Unsupported Child's Benefit Taxable

UCB Is Completely Non-Taxable

The Unsupported Child's Benefit (UCB) and the Orphan's Benefit (OB) are both non-taxable payments. You do not include them as income in your annual tax return, and Inland Revenue does not assess them for income tax purposes.

This applies to the base weekly rate and every supplementary payment that comes with it:

• Base weekly UCB/OB payment — non-taxable
• Clothing Allowance — non-taxable
• Establishment Grant ($350 one-off) — non-taxable
• Holiday Allowance — non-taxable
• Birthday Allowance — non-taxable
• School and Year Start-up Payment — non-taxable

Inland Revenue treats these payments as non-taxable. They are for the child's maintenance, not the caregiver's taxable income.

How It Interacts With Your Other Income

Because UCB is non-taxable, it doesn't push you into a higher tax bracket. If you're earning $50,000 from employment, your income tax is calculated on $50,000 — the UCB payments sitting on top don't factor in.

For a grandparent on NZ Superannuation, this is particularly significant. NZ Super is taxable income. The UCB sitting alongside it is not, so it does not add to your taxable income. Inland Revenue does, however, include UCB and OB as income when calculating Working for Families entitlement.

The Working for Families Catch

While the tax treatment is favourable, there's one trade-off that catches some caregivers by surprise. Under Section YA 1 of the Income Tax Act 2007 and the SSA 2018 settings, a child receiving UCB or OB is excluded from the definition of "dependent child" for specific Inland Revenue tax credits:

• Family Tax Credit — you cannot claim this for the child on UCB
• Best Start Tax Credit — you cannot claim this for the child on UCB
• In-Work Tax Credit — you can still claim this if you meet the required work hours

If you have other biological or adopted children in the same household, they remain eligible for Working for Families credits. The exclusion applies to the child receiving UCB/OB, and Inland Revenue includes UCB/OB as income when calculating the household's Working for Families entitlement.

The effect on your household depends on which Working for Families credits you would otherwise qualify for.

What About Child Support Payments?

If Inland Revenue collects child support from the child's natural parents and the amount exceeds the weekly UCB rate, the excess is passed through to you. That excess child support may be treated as income for specific supplementary assistance calculations like Temporary Additional Support, but the UCB payment itself remains non-taxable regardless.

The Bottom Line

You don't need to declare UCB on your income tax return. It doesn't add to your taxable income or affect your PAYE or income tax assessment. Inland Revenue does include UCB/OB as income when calculating Working for Families entitlement.
