Is Your Property Structure Actually Protecting You?

I was recently on Property Matters (Barfoot & Thompson's Monday finance and tax slot – you can listen to the podcast here) talking through the questions I get asked most often by property investors: structure, trusts, personal guarantees, and what's actually deductible. A few themes came up that are worth putting down properly, because they're the same issues I see catching clients out at GRA week after week. 

One thing worth saying upfront: none of this is a substitute for advice on your own situation. Structuring decisions, in particular, depend heavily on your individual circumstances, and getting advice before you act (rather than after) is what keeps you on the right side of the rules.

Why Does Getting Your Structure Right at the Start Matter So Much?

It is almost always cheaper to set up the right structure at the beginning than to fix it later. A trust might cost a couple of thousand dollars to establish; a company perhaps eight hundred. Restructuring after the fact is a different story: moving property between entities can trigger bright-line issues, depreciation recovery, or GST, especially where a property has been traded or developed. Not to mention the legal costs involved with transferring the titles (conveyancing). 

I still see the same mistake at the top of the list: people buy their first rental without getting advice on how it should sit alongside their employment, their business, and their other assets. Doing your own tax return can compound the problem. Plenty of people manage it correctly, but the recent run of tax changes has made filing a return far less straightforward than it used to be.

What Does "Separating Risk from Wealth" Actually Mean?

Risk is anything that can generate a claim against you: trading, employing staff, contracting, business partnerships, debt. Wealth is what you're trying to protect: the family home, rentals, a share portfolio, retained capital in a company. The general principle hasn't changed: trading in a company, property held separately (usually in a trust), family home in the family trust.

There's also a tax overlay to be aware of. The trust tax rate now sits at 39%, the same as the top personal rate. Companies sit at 28%, but treat that as a deferral rather than a saving: once profits are paid out as dividends to a shareholder on the top rate, imputation credits only take you so far and the balance is topped up to 39%. This is genuinely useful context if you're setting up a new structure or planning your next purchase, but it isn't, on its own, a reason to unwind an existing structure. The right entity for a new acquisition depends on the full picture: asset protection, how the portfolio fits with your other assets, and the practical cost of running it, not just the headline tax rate.

Do Family Trusts Really Protect Your Assets?

Yes, but not unconditionally, and that’s fine. Trusts are an incredibly useful tool for asset protection. The fact that they may not be 100% bulletproof if they are not administered well is often used by scaremongers to set aside the usefulness of trusts. However don’t throw out the baby with the bathwater. 

What a well-run trust does protect against: business failure, creditors, and most third-party claims. If a creditor comes after you and everything is held personally, a court can order you to sell assets to pay them. If those same assets sit in a properly managed trust, genuinely independent, with no problematic debt linking back to you, you're in a far stronger position to negotiate rather than being forced to sell.

What a trust does not protect against: your own conduct as trustee, debt the trust owes that's backed by a bank guarantee (often overlooked), a relationship-property claim over jointly used assets like the family home, and assets moved into the trust when you were already exposed — both the Property Law Act and the Insolvency Act allow dispositions that prejudice creditors to be clawed back. A trust also won't help if it isn't run properly. Sloppy administration is the most common way trusts lose the protection people assume they have.

So the honest answer is: a trust puts you in the strongest available position, not a bulletproof one. At GRA we strongly recommend the use of trusts to protect your family home and assets. 

Bear in mind, too, that it is expensive and time-consuming for creditors to challenge a trust – it’s usually only disgruntled spouses or financially well-backed organisations where significant amounts of money are involved. GRA's family trust service can help you set one up correctly or review an existing trust.

How Big a Risk Are Personal Guarantees, and Can You Avoid Them?

Realistically, no, you can’t avoid guarantees with bank debt for investment property. Banks lend against your ability to service the loan, so a personal guarantee is close to unavoidable.

What catches people out is scope. Banks will often ask to cross-secure everything you own and take a guarantee over "all obligations," not just the loan in question. Many investors accept this as standard when it can often be negotiated down: limiting the facilities covered, avoiding cross-guarantees, and considering split-bank lending so debt sits with separate banks in separate structures. You'll likely still give a personal guarantee, but it comes back to you personally rather than dragging in assets that were meant to be protected elsewhere.

Personal Ownership, LTC, Company or Trust: Which One Fits?

There's no single right answer here; it genuinely depends on your circumstances. This is squarely a "get advice before you buy" question, since the entity you choose when you acquire a property is far easier to get right the first time than to change later. Here's the honest trade-off on each:

● Personal ownership: simple and cheap, and still the most common option by default because most people buy a rental without seeking structuring advice first. The downside is that you're taxed at your top marginal rate, there's no creditor protection, and there's no flexibility in how profit is allocated.

● Look-through company (LTC): an ordinary company that elects to have profits and losses flow through to shareholders rather than being taxed at the company level. LTCs were far more popular when losses could offset personal income; loss ring-fencing took a lot of that appeal away, though they still have a place in some situations.

● Trust: offers the strongest asset protection, but the case for one looks very different for someone with a single property versus a ten-property portfolio.

● Company: can suit a portfolio that's already generating taxable profit, since the 28% company rate is lower than the 39% top personal rate — though again, that is a deferral rather than a permanent saving once you extract the profits. This is a factor to weigh when you're deciding how to hold a new purchase, not a reason on its own to reorganise a portfolio you already own.

Whatever structure you're considering, weigh the ongoing cost of running it (accounting, compliance, administration) against the genuine asset-protection or practical benefit it gives you. 

Renovation or Repair? Where the Deductibility Line Gets Blurry

Rates, insurance, interest, property management fees, general repairs and maintenance, and depreciation on chattels are all generally deductible. There's no secret list of extra expenses beyond that, although it’s not an exhaustive list.

The grey area is distinguishing a deductible repair from an improvement, and a $15,000 renovation can sit right on that line. The test starts with identifying the asset: the building as a whole is one large asset. Replacing an old kitchen with a basic flat-pack version and a simple benchtop can genuinely be like-for-like, even though it looks newer. A kitchen doesn't automatically become an "improvement" just because it looks nicer than what was there before; sometimes 1980s hand-crafted cabinetry was better built than its replacement. So is the replacement an improvement? Not likely. 

Can You Restructure Your Debt to Make More Interest Deductible?

No, you can’t take actions or restructure purely for a tax advantage. However tax advantages often come about through effective and legitimate risk protection strategies.

If you have a large mortgage on your own home and an unencumbered rental sitting alongside it, it is worth looking at whether it is sensible to have all your debt secured against your home (spoiler: its not.) Ideally you have as little secured against your home as possible and all your debt secured against the rental.

The critical point, and the one that trips almost everyone up, is that deductibility follows the use of the borrowed money, not which property the loan happens to be secured against. Asking the bank to move the security from your home to the rental works well for risk protection but achieves little in terms of interest deductibility; the funds were still used to buy the house you live in. 

Once again, it is critical to get good advice on the best way to go about restructuring for asset protection with the best overall outcomes. IRD looks closely at structures that have been changed for no reason other than the tax result, so the case for a trust or company should stand on its own asset-protection or portfolio-management merits, with any tax benefit sitting alongside it rather than driving it.

Bright-Line Is Back to Two Years: Does That Mean You're in the Clear?

Not necessarily, and this is one of the more misunderstood points in property tax. Bright-line was added on top of tax rules that already existed to catch property speculation; it didn't replace them. A sale can still be taxable if the property was bought with an intention to resell, if there has been a subdivision within ten years of purchase, or a major subdivision at any time. A zoning change or a resource consent can also do it, but only where you sell within ten years of acquiring the land and at least 20% of the gain is attributable to that change. And the trigger most people miss entirely: if you, or anyone associated with you, deals in, develops or builds on land as a business, sales can be taxable regardless of all of the above.

The two-year bright-line window is a backstop, not a clearance certificate. Get advice before you sell if any of those other triggers might apply. The alternative is IRD determining a sale was taxable after the money's already been spent, with interest and penalties on top. For more detail, see GRA's bright-line and interest deduction update.

What's the GST Trap for Airbnb and Other Short-Stay Owners?

Starting with the change that still catches people by surprise: since 1 April 2024, platforms such as Airbnb and Bookabach have had to charge 15% GST on New Zealand short-stay accommodation whether or not the owner is GST registered. If you are not registered, the platform passes you back an 8.5% flat-rate credit and remits the other 6.5% to Inland Revenue. Separate from that, the registration threshold is $60,000 of taxable supplies for a single entity in any rolling 12-month period — turnover from all of that entity's taxable activities, not just the short-stay income, and a rolling period rather than a fixed tax year. Cross it and the entity has to register, which brings the property itself into the GST net.

That can mean claiming GST back on the purchase price, but it can also mean paying GST on the eventual sale price. A holiday bach bought decades ago for a modest sum and later sold for well over a million dollars can generate a real GST bill on that sale if it was used for Airbnb and crossed the threshold along the way. Once again, advice is critical.

Mixed-use asset rules add another layer: where a property is both rented out and used privately, expenses need to be apportioned rather than claimed in full. This is genuinely an area where getting an accountant involved before you list the property pays for itself. We've covered this trap in more detail in our article on the holiday home GST trap.

How Could the 2026 Election Change Property Tax?

With the general election on 7 November, tax policy is worth watching, though nothing is settled yet. Positions differ sharply between parties, so it's worth understanding both the case for change and the case for the status quo:

●  The current government has not signalled major changes to the existing settings: bright-line at two years, interest deductibility restored, current trust and company tax rates.

●  Labour has proposed a flat 28% capital gains tax on residential investment and commercial property, applying only to gains accruing from 1 July 2027, with valuations required at that date so earlier growth stays untaxed. The family home, farms, shares, KiwiSaver and business assets would be excluded.

●  The Opportunity Party has proposed a land value tax of 1.75% on urban land and 0.5% on rural land, funding a universal “citizen’s income”.

●  The Greens have proposed a 2.5% wealth tax on net assets above $10 million per individual (or $20 million per couple), excluding the family home, alongside a new 45% top personal rate on income over $160,000. More directly relevant here, they would restore the bright-line test to ten years and again deny interest deductibility on residential rentals.

The case for a capital gains or land tax is usually framed around broadening the tax base and dampening speculative demand; the case against such a tax centres on compliance cost, the risk of taxing paper gains investors haven't realised in cash, and the disruption of yet another structural change on top of the bright-line and interest-deductibility shifts of the past few years. Whatever your view, property remains a live political issue, and structures put in place now should be flexible enough to absorb a change in the rules rather than requiring another expensive rebuild.

One Thing Every Investor Should Check This Year

If I had to pick a single action, it's this: find out what you've actually personally guaranteed. Business owners in particular often don't have a clear picture of what they've signed up to over the years. Guarantees themselves are not recorded on any public register, so there is no single search that will find them: ask each bank in writing for a full list of the guarantees you have given and what they cover, check the titles at LINZ for mortgages, and search the Personal Property Securities Register for general security agreements over your companies. Most people are surprised by what comes back.
