This NZ Airbnb GST calculator is a free browser tool that checks whether your short-stay accommodation income crosses the NZ$60,000 GST registration threshold, then shows the 15% output GST the platform collects, the flat-rate credit you keep if you stay unregistered, and the input GST you could claim if you register. Nothing is uploaded and no sign-up is needed.
NZ Airbnb GST registration — the $60,000 rule
If your NZ short-stay accommodation income (Airbnb, Bookabach, Booking.com, Trip.com) exceeds NZ$60,000 in any rolling 12-month period, you must register for GST within 21 days. Short-stay means bookings under 4 weeks duration. The $60,000 threshold uses gross taxable supplies — before platform fees and expenses are deducted. Once registered, you charge 15% output GST on bookings, file GST returns (typically 6-monthly), and can claim back input GST on business expenses.
The 2024 marketplace GST rule changes everything
From 1 April 2024, electronic marketplaces facilitating short-stay accommodation in NZ are legally required to collect 15% GST from guests and pay it to IRD — even if the host is not GST-registered. As a host, this means: (a) if you are NOT registered, you receive only the net price (1/1.15 of guest price = 86.96%) and cannot claim back any input GST; (b) if you ARE registered, the platform still collects output GST but you can claim back 15% GST on business expenses (cleaning, supplies, utilities, mortgage interest on commercial property loans, depreciation on chattels).
Example: NZ$39,600 vs NZ$66,000 annual income
Below threshold: 180 nights × NZ$220/night = NZ$39,600. Under $60k threshold — no need to register. Platform deducts 15% GST = NZ$5,165 (sent to IRD) + 3% platform fee NZ$1,188. Your net before income tax: NZ$33,247. Above threshold: 300 nights × NZ$220 = NZ$66,000 → MUST register. As registered host: output GST NZ$8,609 paid to IRD via platform. NZ$8,000 expenses incl GST → input GST claimable NZ$1,043. Net GST = NZ$7,566 paid; input claim NZ$1,043 cashflow back. Plus you can deduct expenses for income tax separately.
How to use this Airbnb GST calculator
Enter your average nightly rate (including GST as charged to the guest), nights booked per year, your platform fee percentage (Airbnb host fee is ~3%, Bookabach 12-15%), and your GST-exclusive annual expenses. The calculator estimates annual gross, whether you hit the $60k threshold, the output GST collected by the platform, and the input GST you could claim back if registered.
The 8.5% flat-rate credit unregistered hosts keep
The marketplace rules do not simply take 15% off an unregistered host and leave it there. Because a non-registered host cannot claim input GST on cleaning, power, or supplies, the legislation hands back a flat-rate credit of 8.5% of the GST-exclusive value of the accommodation, and the platform pays it to you along with your payout. On a NZ$220 nightly booking the guest price includes NZ$28.70 of GST, the platform remits that to Inland Revenue, and you receive roughly NZ$16.25 back as the flat-rate credit — so your effective GST cost is nearer 6.5% than 15%. Two things trip hosts up. First, the credit is not taxable income, so do not double-count it in your IR3. Second, it stops the moment you register: a registered host claims real input GST instead, which is better only when your actual GST-bearing costs exceed about 8.5% of turnover. Compare both paths before electing to register.
The GST trap when you sell the property
Registering for GST on a short-stay property is easy to enter and expensive to exit. Once the property is part of your taxable activity, its eventual sale is a taxable supply — you may owe output GST of 3/23 of the sale price, which on a NZ$900,000 sale is roughly NZ$117,000. The same charge applies if you simply stop renting it out and move in, because ceasing the taxable activity triggers a deemed supply at market value. Neither event produces cash to pay the bill, which is why hosts near the threshold often deliberately stay under NZ$60,000 rather than register to claim a few thousand dollars of input GST. If the property is jointly owned, held in a trust, or was bought before you started hosting, get the apportionment confirmed in writing before you register — the general rules are set out by Inland Revenue, but the arithmetic is property-specific.
