Depreciation is a non-cash tax deduction — it reduces your taxable rental income without requiring a cash outlay in the year of the claim. In NZ, building depreciation was removed in 2011 for residential properties, but chattels depreciation remains and is worth hundreds to thousands per year in tax savings.
You cannot depreciate the building structure of a residential rental property in NZ (removed in 2011). You can depreciate chattels — carpets, appliances, curtains, heat pumps, hot water cylinders. A chattels valuation (one-time cost of $400–$700) identifies these items at purchase and enables annual depreciation deductions of typically $2,000–$6,000/year. Worth doing on every rental property purchase.
Building Depreciation: Not Available
Prior to April 2011, NZ landlords could depreciate the residential building structure. This was removed because IRD data showed most residential properties were actually appreciating in value — depreciation was distorting the tax system.
Current rule: No depreciation on the building or land. This applies to:
- The house structure itself
- Land (has never been depreciable)
- Permanent improvements to the structure (e.g., extensions, reroofing)
Commercial property exception: Commercial and industrial buildings with estimated useful life over 50 years may be eligible for 0% depreciation. Buildings with shorter EUL may qualify. Check with a tax adviser for commercial property.
Chattels Depreciation: Still Available
Chattels are moveable items that are part of the rental property. These depreciate over time and can be claimed annually.
IRD depreciation methods:
- Diminishing Value (DV): Higher deduction in early years, decreasing over time. Most commonly used for chattels.
- Straight Line (SL): Equal deduction each year over the asset’s life. Less common.
DV calculation: $$\text{Annual depreciation} = \text{Opening book value} \times \text{DV rate}$$
In year 1, opening book value = chattels valuation amount. Each subsequent year, the value reduces by the depreciation claimed.
Common Chattels and IRD Depreciation Rates
| Chattel | DV rate | SL rate | Economic life |
|---|---|---|---|
| Carpet (domestic) | 25% | 17.5% | ~7 years |
| Dishwasher | 25% | 17.5% | ~7 years |
| Oven / cooktop | 30% | 21% | ~6 years |
| Rangehood | 25% | 17.5% | ~7 years |
| Heat pump / air conditioner | 16% | 10.5% | ~12 years |
| Hot water cylinder | 8% | 5.5% | ~20 years |
| Curtains / blinds | 25% | 17.5% | ~7 years |
| Washing machine | 21% | 14% | ~9 years |
| Fridge / freezer | 21% | 14% | ~9 years |
| Light fittings | 18% | 12.5% | ~10 years |
| Letterbox, clothesline | 13% | 9% | ~15 years |
| Garden shed | 13% | 9% | ~15 years |
IRD publishes the full depreciation rate schedule at ird.govt.nz. Rates are updated periodically.
How a Chattels Valuation Works
A chattels valuation is performed by a specialist valuer (not a real estate agent) at or around the time of property purchase. The valuer:
- Visits the property (or assesses from detailed photos/list)
- Identifies every depreciable chattel
- Assigns each item its value at the date of purchase
- Produces an IRD-accepted schedule of chattels values
Cost: $400–$700 for most residential properties. Some valuers charge more for complex properties.
Timing: Do this at the time of purchase. Backdating a valuation years later is difficult and may not be accepted by IRD.
Example: Annual Depreciation on a $750,000 Rental Property
A new landlord purchases a 3-bedroom home in Christchurch for $750,000. A chattels valuation identifies:
| Chattel | Valuation | DV rate | Year 1 depreciation |
|---|---|---|---|
| Carpet | $4,500 | 25% | $1,125 |
| Heat pump | $3,000 | 16% | $480 |
| Oven / cooktop | $1,200 | 30% | $360 |
| Curtains / blinds | $2,500 | 25% | $625 |
| Hot water cylinder | $2,000 | 8% | $160 |
| Dishwasher | $800 | 25% | $200 |
| Rangehood | $600 | 25% | $150 |
| Light fittings | $1,800 | 18% | $324 |
| Total | $16,400 | $3,424 |
Tax saving at 33%: $3,424 × 33% = $1,130 saved in Year 1
The $500 valuation cost generates $1,130 in tax savings in Year 1 alone — a 2× return in the first year, then ongoing savings for 5–10 years.
Depreciation and the Ring-Fencing Rules
Chattels depreciation is a deductible expense — it contributes to your rental property deductions. If your property is already generating a rental loss (common for negatively geared Auckland properties), the depreciation deduction increases the loss.
Because of ring-fencing, this loss carries forward rather than offsetting salary immediately. But it:
- Reduces the rental income you need to generate before becoming tax-positive
- Can be used against future rental income or on the bright-line gain when you sell
Depreciation Recovery on Sale
When you sell the rental property, IRD may require you to repay some of the depreciation claimed — this is called depreciation recovery (also called clawback).
How it works:
- If you sell a chattel for more than its depreciated book value, the excess is income in the year of sale
- If you sell for less, it’s a loss (deductible)
Example:
- Oven depreciated over 4 years: original value $1,200, now book value $400 (after $800 of depreciation claimed)
- Property sold — oven included in sale. IRD attributes nil value to oven on sale (bundled in property price)
- Recovery: $0 − $400 = −$400 loss (you can claim this as a deduction)
In practice, depreciation recovery on chattels at property sale is complex. Your accountant calculates this on the final rental return covering the year of sale.
Capital Improvements vs Chattels
A key distinction: capital improvements are not immediately deductible and are not depreciable as chattels — they’re added to the property’s cost base.
| Item | Treatment |
|---|---|
| Replacing carpet like-for-like | Chattel (repair/replacement) — fully deductible |
| Adding carpet where there was none | Capital improvement — add to cost base |
| Replacing oven with same model | Chattel — deductible |
| Replacing kitchen including benchtops, cabinets | Capital improvement — cost base |
| Adding a heat pump where none existed | Capital improvement — but heat pump itself is a chattel depreciable at 16% |
The line between “repair” and “capital improvement” is grey. When in doubt, consult a tax adviser. IRD publishes guidance in IS 12/03.
Low-Value Asset Write-Off
From 17 March 2021, assets costing $1,000 or less can be written off (100% deducted) in the year of purchase rather than depreciated over their useful life.
For landlords: Any chattel costing under $1,000 at purchase can be immediately deducted — no need to track it for depreciation over years. This simplifies accounting for small items (kitchen utensils, light fittings, minor appliances).
Items over $1,000 must be depreciated using the standard DV or SL rates.
Do You Need a Chattels Valuation?
You don’t legally need a professional valuation — you can estimate chattel values yourself. But:
- Self-estimated values are more likely to be challenged by IRD in an audit
- A professional valuation creates a defensible, documented record
- The cost is deductible (accounting expense)
Recommendation: Always get a professional chattels valuation. The $500 cost pays back in year 1.
