A trust is built for asset protection and succession; a company is built for trading and a flat tax rate. For New Zealand rental property, ring-fencing and the bright-line test apply to both, so neither structure is a tax shortcut. The choice is mostly about protection, control and the cost you are willing to carry.
The two options at a glance
Investors holding residential rentals sometimes weigh a trust against a company. They solve different problems. A trust separates legal ownership from benefit, which suits asset protection and passing wealth on. A company is a trading vehicle with a flat 28% tax rate and limited liability. Some investors even use both, with a trust owning the shares in a company.
- Trust — trustees hold the property for beneficiaries; income is taxed as trustee income or distributed to beneficiaries at their rates.
- Company — a separate legal person, files an IR4, pays 28% on profit, with money reaching you as salary or dividend.
A common arrangement blends the two: a trust owns the shares in a company that holds the property, or in a look-through company. That can combine a company's trading structure with a trust's protection and succession features. It is also more complex and more expensive to run, so it suits larger or longer-horizon portfolios rather than a first rental.
Tax treatment compared
| Point | Trust | Company |
|---|---|---|
| Tax on retained profit | Trustee rate (currently 39%) | Flat 28% |
| Distributions | Beneficiary income at their rate | Dividends, with imputation credits |
| Rental ring-fencing | Applies | Applies |
| Bright-line on sale | Applies | Applies |
| Main strength | Asset protection, succession | Trading, flat rate, liability shield |
The crucial point is that the tax basics do not change between them. Rental ring-fencing holds residential losses back against future rental income in both. The bright-line test taxes a sale inside the relevant window in both. Neither structure makes a residential rental loss offset your other income, and neither escapes bright-line.
The trustee tax rate is an important recent change. Trustee income that is retained in the trust is now generally taxed at 39%, aligning it with the top personal rate, which removed much of the old rate-arbitrage reason to use a trust purely for tax. Income that is distributed to beneficiaries is taxed in their hands at their own rates instead, subject to the rules, so distribution policy matters more than it used to.
Cost and cashflow
Both structures cost more to run than holding personally. A company files an IR4 and a Companies Office return; a trust needs trust accounts, trustee decisions and ongoing administration, and trustee income is taxed at the top 39% rate where it is not distributed. A company's flat 28% can look attractive on retained profit, but the rest of the tax follows when you draw the money out.
For a single rental running near breakeven, the cashflow gain from either structure is usually small, while the compliance cost is certain. The economics improve as the portfolio grows.
Running costs differ in character. A company's compliance is fairly mechanical: an IR4, financial statements, and an annual return to the Companies Office. A trust's costs are more about good governance: documented trustee decisions, separate trust accounting, and care that the trust is administered as a real trust and not just a name on a title. Neglected, a trust can be challenged, which defeats the protection it was set up to give.
Risk and admin
This is where the choice is really made. A trust is the stronger asset-protection and succession tool: it can keep property outside your personal estate and pass it on without the asset changing hands at death. A company gives limited liability for the trading activity and a clean structure for multiple owners.
Both add formality. A trust must be administered properly to be respected, with genuine trustee decision-making and clean records. A company must keep its accounts and current accounts in order. Done sloppily, either can be challenged, so the admin is not optional.
Which suits which owner
- Asset protection and passing property to family — a trust is the natural fit.
- Trading activity, several owners, retained profit — a company's structure and flat rate help.
- One rental near breakeven — often neither is worth the cost yet; personal ownership may be enough.

In plain English: neither structure dodges ring-fencing or bright-line, so choose a trust for protection and succession, a company for trading and a flat rate, and personal ownership when one small rental does not justify the cost.
