Family trust tax benefits: what they are
Setting up a family trust can be one of the most effective ways to manage and transfer wealth while keeping your tax bill in check. In New Zealand, trustee income that is not distributed to beneficiaries is taxed at a flat 39% rate, which is the highest marginal rate. The real advantage comes when a trust strategically distributes income to beneficiaries in lower tax brackets, avoiding that 39% hit.
If you are not familiar with the basic mechanics, read our detailed guide on how a family trust works in New Zealand.
Key points:
- A family trust separates asset ownership from personal ownership.
- Income splitting can lower the overall family tax rate compared to paying the 39% trustee rate on retained income.
Income-splitting advantages of a grantor trust
One of the most practical family trust tax benefits in New Zealand is the ability to split income among multiple beneficiaries. Instead of paying the flat 39% trustee income tax rate on all retained income, a trust can distribute some or all of its income to beneficiaries who are on lower marginal tax rates. This can mean thousands of dollars in tax savings each year.
Why income splitting works:
- Distributions to adult beneficiaries are taxed at their personal rates, which may be lower than the trustee rate.
- Reduces the overall family tax bill by shifting income away from the 39% bracket.
Table: Example of income splitting with a family trust
| Beneficiary | Taxable Income Before Trust | Trust Distribution | New Taxable Income | Tax Rate | Total Tax Payable |
|---|---|---|---|---|---|
| Parent (39% bracket) | $180,000 | $0 | $180,000 | 39% | $70,200 |
| Adult child (17.5%) | $20,000 | $20,000 | $40,000 | 17.5% | $7,000 |
| Adult child (10.5%) | $10,000 | $15,000 | $25,000 | 10.5% | $2,625 |
| Total family tax | — | — | — | — | $79,825 |
If the $35,000 in trust income had been taxed at the trustee rate of 39%, it would have cost $13,650 in tax. By distributing it to the children, the tax on that portion drops to just $9,625, saving the family $4,025.
If your trust is inactive, be sure to review the non-active trust tax rules to stay compliant and avoid unnecessary filings.
Estate and gift tax reduction via irrevocable trusts
An irrevocable family trust can permanently move assets out of your taxable estate. In New Zealand, this does not remove all tax obligations, but it can reduce the exposure to the 39% trustee rate on retained income by ensuring income is directed to beneficiaries with lower rates.
Advantages include:
- Lower or eliminate estate tax by transferring assets early (relevant in jurisdictions with estate taxes).
- Avoid the trustee 39% rate on certain income by distributing strategically.
According to SmartAsset, irrevocable trusts can also shield assets from future creditors and lawsuits, which is an important consideration for high-net-worth families.

Capital gains and generation-skipping advantages
Family trusts can also be used to reduce capital gains tax and pass wealth efficiently to future generations. While New Zealand currently has no general capital gains tax, certain transactions (like the bright-line property rule) can trigger taxable gains. If these gains are retained by the trust, they can be hit by the 39% trustee rate—distributing them to beneficiaries on lower rates can significantly reduce the tax bill.
Ways trusts help with capital gains and GSTT (generation-skipping transfer tax in other jurisdictions):
- Distribute taxable gains to beneficiaries with lower marginal rates.
- Plan multi-generational transfers to avoid extra tax layers in certain tax systems.
Tax-efficient asset protection strategies
One of the less discussed family trust tax benefits is the ability to combine asset protection with tax efficiency. By placing high-value assets into a trust, you can reduce the risk of losing them in the event of business failure or litigation, while still managing the tax impact of income they produce. Retaining income may trigger the 39% trustee rate, so careful distribution planning is key.
Benefits:
- Protect property and investments from personal creditors.
- Avoid the high trustee rate by allocating taxable income to beneficiaries when possible.
If you prefer an independent party to oversee this process, consider appointing a professional trustee to manage compliance and decision-making.
Bonus for family trust tax benefits
Beyond the headline tax advantages, family trusts can also be tailored to support life goals—like funding education, covering medical costs, or supporting retirement—while managing exposure to the 39% trustee rate. By structuring distributions carefully, you can meet these goals without incurring unnecessary tax.
Examples of bonus benefits:
- Allocate income to fund a grandchild’s university fees at lower tax rates.
- Use trust income to cover major life events without triggering the 39% rate on retained funds.
Conclusion
A well-structured trust can deliver powerful family trust tax benefits—from lowering exposure to the 39% trustee income tax rate to enabling income splitting, asset protection, and multi-generation wealth transfers. The key is understanding when to retain income and when to distribute it to beneficiaries in lower tax brackets. By combining good trust governance with sound tax planning, you can protect your assets, reduce tax costs, and support your family’s goals for years to come.
Before setting up or restructuring your trust, work with a qualified adviser who understands both the legal framework and New Zealand’s trust tax rules. With the right plan, the savings can be significant and long-lasting.
