What a GST bridge loan actually is in New Zealand
A GST bridge loan in NZ is a short-term, property-backed facility designed to fund the 15% Goods and Services Tax portion of a commercial property purchase on settlement day. If your property purchase agreement is marked "Plus GST" and your senior bank loan only covers the net purchase price, a GST bridge loan supplies the missing 15% cash so settlement completes without penalty.
Here is the problem buyers run into: when you buy a commercial building for $2,000,000 plus GST, the total gross cash required on settlement day is $2,300,000. Your bank approves a 65% loan-to-value ratio (LVR) mortgage against the $2,000,000 valuation, providing $1,300,000. You put in your $700,000 cash equity. But that still leaves a $300,000 GST shortfall due at 4:00 PM on settlement day.
Because paying an extra 15% at settlement when you were expecting zero-rating is about as welcome as a rain delay on the 18th hole, a GST bridge loan bridges the timing lag. The non-bank lender advances the $300,000 GST portion to your solicitor. Once settlement completes, your accountant files your GST return with Inland Revenue (IRD), and the $300,000 input tax refund pays off the bridge loan in full.

Why commercial property attracts 15% GST (and when zero-rating fails)
Under New Zealand tax law, most commercial property transactions between two GST-registered businesses are subject to Compulsory Zero-Rating (CZR) under section 11(1)(mb) of the Goods and Services Tax Act 1985. When CZR applies, GST is charged at 0%, meaning no cash GST changes hands on settlement day.
However, zero-rating is not automatic. If any legal or administrative condition is missed, the transaction defaults to standard 15% GST. Here are the four common scenarios where zero-rating fails:
Purchaser GST Registration Delay at Settlement
You sign an agreement on a commercial warehouse or retail unit, but your purchasing company or trust has not completed its GST registration with Inland Revenue before settlement day. Because compulsory zero-rating requires both parties to be GST-registered at the time of supply, the transaction must settle at standard 15% GST. A GST bridge loan provides the 15% cash to settle on time.
Vendor Sells "Plus GST (If Any)" Due to Classification Disputes
The vendor or their solicitor is unsure about their GST status or the historical supply classification of the property. To protect themselves, they insist on adding 15% GST to the purchase price at settlement. A short-term bridge funds the GST portion while your accountant claims the full input tax credit on your next GST return.
Mortgagee Sales & Distressed Commercial Disposals
In bank mortgagee sales or receiver sales, the selling bank routinely demands settlement on a gross "Plus GST" basis without warranties regarding zero-rating. Mainstream mortgage lenders only fund against the net valuation, leaving a 15% funding shortfall on settlement day.
Subdivisions, Bare Land & Mixed-Use Properties
When purchasing bare commercial land, development sites, or mixed-use commercial buildings where a portion is residential, zero-rating rules may not apply across the entire asset. A GST facility covers the taxable portion until IRD processes your development input claim.
(Yes, IRD really does want the GST return filed correctly before paying the refund. No, a sticky note on the contract does not count.)

How a GST bridge loan works: Settlement to IRD refund
A GST bridge facility operates as a three-stage process from settlement day through to full loan discharge:
Stage 1: Settlement Day Advance
On settlement day, your senior lender advances their standard mortgage funds (e.g. 65% LVR), you provide your cash equity, and the GST bridge lender advances the exact 15% GST amount directly to your solicitor trust account. Your solicitor completes settlement and pays the gross purchase price to the vendor.
Stage 2: Immediate GST Return Lodgement
As soon as settlement completes and the tax invoice is issued, your accountant files your entity GST return with Inland Revenue for the corresponding taxable period. The return claims the 15% input tax credit for the property acquisition.
Stage 3: Direct IRD Refund & Loan Discharge
Under an irrevocable payment instruction arranged during loan setup, Inland Revenue deposits the 15% refund directly into the lender escrow account. The facility principal is repaid in full, capitalised interest is cleared, and any remaining balance is released to you.

Interest & repayment: Capitalised interest with zero monthly cash drain
Because a GST bridge loan is held for a very short period (typically 30 to 90 days), non-bank lenders structure the facility to protect your working capital:
1. Capitalised Interest (Standard Structure)
The interest cost for the expected 1 to 3 month term is calculated upfront and added to the total facility balance. You make zero monthly payments during the loan. When the IRD refund arrives, it covers both the principal advance and the capitalised interest.
2. Retained Interest Reserve
An interest reserve is withheld from the gross facility limit at drawdown. Each month, the lender draws interest from this reserve. Your operational trading accounts and rental cash flow remain completely untouched.
3. Early Repayment with No Break Fees
If Inland Revenue processes your refund faster than expected (e.g. within 10 to 15 working days), non-bank GST facilities allow immediate repayment. Interest is charged only for the actual days the facility was drawn, subject to any minimum term specified in your term sheet.

What NZ non-bank lenders check to approve a GST bridge facility
Because the primary exit on a GST bridge is a statutory tax refund from the New Zealand government rather than property refinancing, underwriting is fast and straightforward:
Signed Sale & Purchase Agreement (Plus GST)
A fully executed contract specifying the purchase price and confirming the transaction is subject to 15% GST on settlement.
Valid GST Registration & IRD Confirmation
Evidence that the purchasing entity is registered for GST (or has an application in progress with Inland Revenue) and is legally entitled to claim the 15% input tax credit.
Solicitor / Accountant Irrevocable Undertaking
A formal undertaking from the borrower solicitor or chartered accountant confirming the GST return will be filed immediately following settlement, with refund proceeds directed to the lender.
Underlying Property Security & GSA
The facility is secured by a second mortgage or caveat over the acquired commercial property, alongside a General Security Agreement (GSA) over the purchasing entity.
If you need to verify an entity legal structure or director details, you can look up company records on the NZ Companies Office Register.

Why mainstream banks decline GST bridging (and the non-bank fix)
If you approach a retail bank (ANZ, BNZ, ASB, Westpac) asking for a standalone 60-day loan to cover a 15% GST gap, the answer is almost always no. Mainstream banks are structured for 25-year amortising debt. Their credit committees treat a 60-day GST tranche as an unserviceable overdraft expansion, requiring weeks of servicing calculations and committee approvals.
If settlement is due in 5 working days, waiting for a bank credit committee guarantees a settlement default notice.
Non-bank commercial lenders operating under the Financial Markets Authority (FMA) framework take a commonsense approach: they understand that the 15% refund is an established statutory entitlement from Inland Revenue. At AML Commercial, our panel of 20 bank and non-bank lenders (7 banks, 13 non-bank lenders) allows us to issue an indicative term sheet in 24 to 48 hours and settle in as little as 72 hours.

When a GST bridge loan isn't the right fit
A GST bridge loan is a specialised settlement mechanism. It is not designed for every situation:
The purchase is already validly Compulsory Zero-Rated (0% GST)
If both the vendor and purchaser are GST-registered at settlement, and the property will be used for making taxable supplies without being a principal residence, the transaction qualifies for Compulsory Zero-Rating (CZR) under section 11(1)(mb) of the GST Act 1985. In that case, GST is charged at 0% and no cash bridging is needed.
You are an unregistered individual purchasing personal property
GST bridge loans require an input tax credit refund from Inland Revenue as the primary repayment source. If you are buying residential property for personal use and cannot register for GST or claim input tax, a GST bridge is not possible.
You need long-term 20 to 30 year commercial mortgage debt
A GST bridge loan is an ultra-short-term facility (typically 1 to 3 months). If you require permanent capital to fund the base commercial property purchase, you need long-term commercial property finance rather than a short-term tax bridge.

FAQs
GST Bridge Loan FAQs
What is a GST bridge loan in NZ?
A GST bridge loan in New Zealand is a short-term commercial loan (typically 1 to 3 months) designed specifically to fund the 15% Goods and Services Tax (GST) portion of a commercial property purchase on settlement day. The loan is repaid in full when Inland Revenue (IRD) releases your GST input tax refund.
How long does it take for IRD to pay a GST refund on commercial property?
Once your accountant files the GST return for the period in which the property settled, Inland Revenue typically processes and pays commercial property GST refunds within 15 working days. If IRD selects the return for a routine document audit, processing can take 4 to 8 weeks, which is why GST bridge facilities are usually structured for 1 to 3 months.
Do I have to make monthly interest repayments on a GST bridge loan?
No. Most non-bank GST bridge facilities feature fully capitalised interest. The estimated interest and lender fees for the 1 to 3 month term are calculated upfront and rolled into the total loan balance. You make zero monthly out-of-pocket payments, and the entire facility is cleared in a single bullet payment when the IRD refund arrives.
Can I get a GST bridge loan if my primary mortgage is with a mainstream bank?
Yes. The senior lender (e.g. ANZ, BNZ, ASB, Westpac) funds their approved portion against the net purchase price (typically up to 60%–70% LVR). The GST bridge lender provides the additional 15% GST required on settlement, secured by a second mortgage, caveat, or General Security Agreement (GSA) behind the bank.
What happens if IRD audits or delays the GST refund?
Because commercial property GST refunds involve significant sums, IRD occasionally requests supporting tax invoices and settlement statements before releasing funds. GST bridge loans include flexible extension provisions (e.g. up to 6 months) to ensure you are not penalized while IRD completes its standard verification.
What documents do I need to apply for a GST bridge loan?
You will need a copy of the signed Sale & Purchase Agreement, confirmation of your purchasing entity GST registration with Inland Revenue, the senior lender loan approval letter, and your accountant or solicitor contact details. AML Commercial can issue an indicative term sheet within 24 to 48 hours.
