Airbnb & Short-Stay Rental Tax NZ 2025-26 & 2026-27 — GST, Income, Ring-Fencing (IRD)

Listing your holiday home on Airbnb, Bookabach, or Booking.com is great cash flow — but the tax rules are some of the most complex in the NZ system. Short-stay accommodation sits at the intersection of income tax, GST, mixed-use asset rules, ring-fencing, and marketplace rules introduced in April 2024. This guide covers everything for the 2025-26 and 2026-27 tax years.

Short-Stay vs Long-Term Residential — The Fundamental Split

The first question IRD asks is whether the activity is short-stay or long-term residential.

Feature	Long-term residential	Short-stay
Typical tenancy	Residential Tenancies Act (28+ days)	Nightly / weekly, holiday rental
GST treatment	Exempt (no GST, no input credits)	Taxable at 15%
Ring-fencing	Yes — losses quarantined	Yes, if property is residential
Mixed-use asset rules	No	Yes, if private use + ≥ 62 days unused
Depreciation on building	No	No
Depreciation on chattels	Yes	Yes

Short-stay is treated as a taxable supply for GST — fundamentally different from a long-term rental, which is GST-exempt. This is why you can accidentally cross the $60k GST registration threshold from short-stay income alone.

GST — The Marketplace Rules (From 1 April 2024)

Under the GST Platform Economy rules (Taxation (Annual Rates for 2023-24, Multinational Tax, and Remedial Matters) Act 2024), effective 1 April 2024:

• Airbnb, Bookabach, Booking.com and similar platforms must charge GST at 15% on every booking of NZ accommodation
• The platform is treated as the supplier for GST purposes
• You — the host — are deemed to have made a zero-rated supply to the platform

If you are not GST-registered

The platform charges the guest GST, pays the output GST to IRD, and then gives you a flat-rate credit of 8.5% of the listing value. You keep this credit; it is not taxable income. You effectively receive 91.5% of the listing price net of platform commission, and do not file GST returns.

If you are GST-registered

You zero-rate your supply to the platform (0% GST) and claim input GST credits on your expenses (cleaning, linen, repairs, commissions paid directly, etc.). You don’t see the 8.5% flat-rate credit — instead you operate the full GST mechanism.

Registering for GST

You must register if your total taxable supplies (short-stay rental + any other GST-taxable activity) exceeded $60,000 in the last 12 months or will in the next 12. You may register voluntarily below $60k if you expect significant input credits (e.g. a renovation).

Note: long-term residential rent doesn’t count toward the $60k threshold because it’s exempt, but short-stay does. A mixed landlord with $40k long-term + $25k short-stay crosses the threshold and must register.

The Mixed-Use Asset Rules

If a property is rented short-stay for part of the year and used privately for part, and is unused for 62+ days, it’s a mixed-use asset. Common examples: family bach used in summer and rented out in winter, or ski lodge rented most of the year but used by the owner in shoulder seasons.

The formula is:

Deductible expenses = Total expenses × (income days ÷ (income days + private days))

• Income days = days rented to arms-length guests at market rates
• Private days = days used by owner, family, or at mates-rates below 80% of market
• Unused days do not count in either direction

The $4,000 opt-out

If gross short-stay income is under $4,000 and the property would run at a loss under the apportionment, you can elect out: declare no income, claim no deductions. Useful for occasional hosts.

The quarantine rule

If expenses for income-producing days exceed income and gross income is 2% or less of the property’s cost, the loss is quarantined (not deductible against other income) and carried forward to offset future income from the same asset.

Ring-Fencing — Residential Rental Losses

Ring-fencing, introduced from 2019-20, applies to residential rental property — including short-stay if the property is residential (as most are). A loss from the property cannot offset salary, business, or other investment income. It carries forward until the property is sold or produces future rental income.

By default each property is ring-fenced separately (property-by-property basis). You can elect for portfolio treatment — losses from one property offset profits from another — but not for any property sold in the year (that one stays standalone).

Ring-fencing does not apply to:

• Commercial property (pure short-stay hotel / motel)
• The owner’s main home
• Mixed-use assets already under the separate mixed-use regime
• Farmland (different rules)

Income Tax — What to Declare

Short-stay income must be declared on IR3 (individuals), IR4 (companies), or IR6 (trusts). Figures go in the “rental income” section unless the activity is so substantial it constitutes a business (e.g. 5+ properties actively managed) — in which case it goes on the self-employment / business schedule.

Deductible expenses (after mixed-use / ring-fencing apportionment) include:

• Interest on loans used to acquire the property (fully deductible for short-stay — the residential interest deductibility limitation does not apply once the property is substantially short-stay for the year)
• Rates, body corporate, insurance
• Repairs and maintenance (not capital improvements)
• Platform commissions and booking fees
• Cleaning, linen, consumables
• Travel to the property for management (strict rules)
• Depreciation on chattels (not on the building)

Worked Example — Coastal Bach

Mereana owns a 3-bedroom bach in Pauanui. During 2025-26:

• Rented short-stay on Airbnb for 120 nights, gross listings $25,000 (platform collects GST)
• Used privately for 30 nights (family summer holiday)
• Unused: 215 nights
• Annual expenses (rates, insurance, interest, repairs, linen, platform fees): $15,000 total

Mereana is not GST-registered. The platform charges guests GST on top of her rates and gives her an 8.5% flat-rate credit. Her gross income is the net amount she receives after platform commission and GST is stripped.

Step 1 — Mixed-use apportionment:

• Income days: 120
• Private days: 30
• Apportionment fraction: 120 ÷ (120 + 30) = 80%
• Deductible expenses: $15,000 × 80% = $12,000

Step 2 — Net taxable income:

Item	Amount
Gross short-stay income	$25,000
Less apportioned expenses	($12,000)
Net rental profit	$13,000

Step 3 — Tax impact:

Mereana already earns $90,000 salary. Adding $13,000 net rental income puts part of it in the 33% bracket:

Source	Amount
Salary	$90,000
Net rental	$13,000
Taxable income	$103,000
Extra tax on rental	~$4,290 (33% effective marginal)

Mereana owes approximately $4,290 additional tax on the rental, due as terminal tax on 7 February 2027. Since this is her first year with rental income and prior RIT was below $5,000, she’s not yet a provisional taxpayer — but she will be for 2026-27.

Common Mistakes to Avoid

• Treating short-stay like long-term rental for GST — short-stay is taxable and counts toward the $60k threshold
• Claiming 100% of expenses on a mixed-use asset — must apportion by income days vs private days
• Claiming interest deductibility limitation against short-stay — the limitation applies to long-term residential; short-stay properties are generally fully deductible
• Forgetting the 8.5% flat-rate credit is not income — it’s GST the platform paid on your behalf
• Using the property yourself at “mates rates” — nights charged below 80% of market count as private, not income, days
• Missing ring-fencing — losses can’t offset salary; they carry forward
• Not registering a trust property correctly — rental profit runs on IR6; trust tax rate is 39% if retained

Record-Keeping Requirements

For 7 years you must keep:

• Platform booking reports (Airbnb / Bookabach export annually)
• Bank statements showing deposits
• Invoices for all claimed expenses
• A diary or calendar showing income days, private days, unused days
• GST returns if registered
