Key Takeaways
- Residential rental income is exempt from GST; you cannot register or claim GST on residential property expenses.
- Commercial property rental is subject to GST, and you can claim GST on related expenses.
- Selling property to GST-registered buyers may qualify for zero-rating, avoiding 15% on the sale price.
- Getting GST wrong on property transactions can result in significant unexpected tax bills.
- Mixed-use properties require careful apportionment between GST-taxable and exempt activities.
GST (Goods and Services Tax) at 15% applies to most goods and services in New Zealand, but property transactions have special rules. For property investors, understanding when GST applies, and when it does not, is essential to avoid costly surprises and structure transactions correctly.
The fundamental distinction is between residential property (generally GST-exempt) and commercial property (generally GST-taxable). However, the details matter significantly, especially when buying or selling properties.
Residential Property and GST
Residential rental accommodation is exempt from GST. This means:
- You do not charge GST on residential rent
- You cannot register for GST based solely on residential rental income
- You cannot claim GST on expenses related to residential rental properties
This exemption covers long-term residential tenancies. It also covers boarding houses and similar accommodation where the stay is the person's principal place of residence.
What This Means Practically:
If you buy a carpet for $2,000 including GST ($260 GST content) for your residential rental, you cannot claim back that $260. The full $2,000 is your cost. Compare this to a commercial property where you could claim the GST back.
Commercial Property and GST
Commercial property rental (offices, retail, industrial) is subject to GST. If you are GST-registered and earn over $60,000 per year from commercial rentals, you must charge GST on rent and can claim GST on related expenses.
Commercial Property GST Benefits:
- ☐ Claim GST on purchase price (if purchased from a registered person)
- ☐ Claim GST on repairs, maintenance, and improvements
- ☐ Claim GST on professional fees (accountant, lawyer, property manager)
- ☐ Claim GST on insurance and other operating costs

Short-Stay Accommodation
Short-stay accommodation like Airbnb creates a grey area. If the accommodation is for less than four weeks at a time and is not someone's principal place of residence, it may be treated as commercial accommodation rather than residential.
This means you might be able to register for GST, claim input tax credits, and need to charge GST on your bookings. If your short-stay income exceeds $60,000 per year, you must register for GST.
The rules around short-stay accommodation can be complex, especially if you use the property for both short-stay and long-term rental at different times. Get professional advice before proceeding.
Buying Property: GST Implications
When purchasing property, GST treatment depends on several factors:
- Private seller: No GST applies regardless of property type
- GST-registered seller, residential property: Usually no GST, as residential property is exempt
- GST-registered seller, commercial property: GST applies unless zero-rated
Zero-Rating on Property Sales
When both buyer and seller are GST-registered, the sale may be zero-rated. This means GST is charged at 0% rather than 15%, so no GST is actually payable on the transaction. The buyer provides a declaration confirming their GST registration and intention to use the property for taxable purposes.
Zero-Rating Example:
You buy a commercial property for $1,000,000 from a GST-registered developer. Without zero-rating, GST would add $150,000 to the price. With zero-rating (because you are also registered), the price remains $1,000,000 with GST at 0%. You save massive upfront costs and cash flow impacts.
Selling Property: GST Considerations
When you sell property, GST treatment depends on your registration status and the buyer's status.
The GST Trap:
If you are GST-registered and sell a commercial property to a non-registered buyer, you must account for GST at 15% on the sale price. On a $1,000,000 sale, that could mean $130,435 in GST payable to the IRD. This can be a nasty surprise if you were not expecting it and the buyer has not paid extra for GST.
This is why sale and purchase agreements must clearly address GST. The contract should specify whether the price includes or excludes GST and what happens in different scenarios.
Going Concern Exemption
Sales of a business as a going concern can be zero-rated. For commercial property, if you sell a tenanted building as a continuing rental business, it may qualify. The tenant continues, the rental income continues, and the business essentially transfers intact.
This exemption helps avoid GST cash flow issues on sales of tenanted commercial properties between registered persons.
Mixed-Use Properties
If a property has both residential and commercial components (such as a shop with a flat above), you need to apportion GST treatment. The commercial portion can have GST claimed and charged; the residential portion cannot.
Apportionment is usually based on floor area or income, but the method should be fair and reasonable. Keep records of how you have calculated the split in case the IRD queries it.
Change of Use Rules
If you claim GST on a property purchase and later change its use (for example, converting commercial to residential), you may need to repay some of the GST claimed. These "change of use" adjustments can result in significant GST liabilities.
Similarly, if you purchase a residential property and later convert it to commercial use, you may be able to claim some GST depending on the circumstances.
Common GST Mistakes
Mistakes to Avoid:
- ☐ Claiming GST on residential property expenses
- ☐ Not addressing GST properly in sale and purchase agreements
- ☐ Assuming all property sales are GST-free
- ☐ Failing to register when required (short-stay over $60,000)
- ☐ Ignoring change of use implications
- ☐ Not keeping proper GST records and invoices
Working with Professionals
GST on property transactions is an area where professional advice is essential. Your accountant should be involved before you sign any purchase or sale agreement involving GST-registered parties or commercial property.
Your lawyer should also ensure the agreement correctly addresses GST, with appropriate warranties about registration status and mechanisms for what happens if GST treatment is different from expected.

Record Keeping
If you are GST-registered, keep tax invoices for all expenses on which you claim GST. These must show the supplier's GST number and the GST amount charged. Without proper invoices, the IRD can deny your claims.

Frequently Asked Questions
Can I register for GST on my residential rental property?
No. Residential rental accommodation is exempt from GST. You cannot register based on residential rental income alone, and you cannot claim GST on related expenses.
Do I have to register for GST if I have an Airbnb?
If your short-stay accommodation income exceeds $60,000 per year, you must register. Below this threshold, registration is optional. The accommodation must be short-stay (under four weeks) to be considered taxable rather than exempt residential.
What is zero-rating and when does it apply?
Zero-rating means GST is charged at 0% instead of 15%. It applies when a GST-registered seller sells land to a GST-registered buyer who will use it for taxable purposes. This prevents cash flow issues of paying GST and then claiming it back.
What happens if I get GST wrong on a property sale?
You could face a significant tax bill. For example, if you sell for $1m and should have charged GST but did not, you may owe the IRD over $130,000. Always get professional advice on GST before signing property contracts.
