Hire purchase, finance lease or operating lease — which one for your gear

There is no single best way to fund a piece of equipment. Hire purchase, a finance lease and an operating lease each split ownership, tax depreciation and GST timing differently, and Inland Revenue's own technical material shows that several assumptions repeated in generic articles about this topic are simply wrong. Get the structure right and you claim GST sooner, depreciate correctly, and know exactly what you own and when. Get it wrong and you find out at year-end, from your accountant, after the return is already filed.

Key Takeaways

Who actually owns the asset, and when

Start with hire purchase, because this is where the most common misreading sits. Inland Revenue's own guidance (QB 23/06) states plainly: "property in the goods remains with the supplier until the goods have been delivered to the purchaser and the total amount payable has been paid." Both conditions have to be met — delivery and full payment — not just delivery. The purchaser is handed possession of the goods well before that point, which is the whole structural feature of hire purchase: possession and legal ownership are deliberately split. IRD sets out three requirements for an agreement to count as hire purchase at all: it's a purchase by instalment payments, the purchaser gets possession before the total price is paid, and the agreement is "at retail" — meaning the purchaser is the actual end user of the goods, not a reseller.

A hire purchase agreement typically runs on a deposit upfront, ongoing instalments, and occasionally a larger balloon payment at the end of the term, IRD notes — structurally similar to a car loan in shape, even though legally it isn't one.

A finance lease works differently again. IRD's interpretation statement on GST and finance leases explains that the term "finance lease" isn't actually defined for GST purposes at all — it's a commercial description for a lease where the lessee's payments are calculated against the value of the goods themselves, not the value of using them, structured so the lessor recovers its capital cost plus a commercial return. Critically, a finance lease will not be treated as a simple lease (an "agreement to hire") where the lessee is the end user and has an option to purchase, or where ownership of the goods passes, or is contractually certain to pass, under the agreement's terms. In practice this means many finance leases are deliberately written so title never automatically transfers — the lessee gets the economic substance of ownership (the capital value, the depreciation profile) without necessarily getting the legal title, unless a purchase option is exercised.

An operating lease, by contrast, is what IRD's technical material calls an "agreement to hire" for GST purposes: the bailment of goods for hire, where no property in the goods passes, or is expressly contemplated to pass, to the lessee at any point. Ownership sits with the lessor for the whole term, full stop, and each rental instalment is treated as a separate transaction rather than progress payments toward eventual ownership.

Hire purchase and the depreciation point most articles get wrong

Here is the genuinely counter-intuitive fact in this whole topic, stated directly in IRD's general depreciation guidance: you can claim depreciation on capital assets you own, lease, or buy under a hire purchase agreement and use, or intend to use, in the business. Read that again for the hire purchase case specifically — the purchaser is entitled to claim depreciation on the asset from the point they start using it, despite the fact that, as established above, legal title has not yet passed to them. Ownership and the right to claim tax depreciation are not the same test, and hire purchase is the clearest example of why.

This matters practically because depreciation isn't optional once an asset qualifies. IRD's guidance is direct: you must claim the depreciation you're entitled to unless you formally elect the asset as non-depreciable property — you generally can't defer it or claim only part of it to smooth a tax result across years. If you've financed equipment on hire purchase and haven't been depreciating it because you assumed you don't legally own it yet, that's worth raising with your accountant immediately, not at the next return.

One practical shortcut worth knowing: assets below a set cost don't need to be depreciated at all — they can be written off immediately. That threshold has moved over time: up to $500 for assets acquired before 16 March 2020, up to $5,000 for the period 17 March 2020 to 16 March 2021, and up to $1,000 for anything acquired from 17 March 2021 onward. For a lot of smaller tools and equipment, the entire hire-purchase-versus-lease question is moot — it's simply cheap enough to expense outright.

GST — the part every generic article gets wrong

This is the section worth reading twice, because the timing difference between hire purchase and a genuine lease is a real, material cash-flow advantage, and it runs opposite to what most people assume.

For a hire purchase agreement, the GST time of supply is the date you enter into the agreement — not the date of each instalment. IRD states this explicitly, and the practical effect is significant: a business buying equipment on hire purchase can claim the full GST deduction in the taxable period it signs the agreement, and — this is the part that trips people up — this applies regardless of whether the business accounts for GST on a payments, invoice, or hybrid basis. IRD's Question We've Been Asked (QB 23/06) confirms it directly: even a taxpayer who is registered for GST on a payments basis, and who would normally only be able to claim input tax as they actually pay each instalment, can instead claim the whole input tax deduction upfront, in the period the hire purchase agreement is signed, before a single instalment has been paid. That is a genuine, sourced cash-flow timing advantage over financing the same purchase through an ordinary deferred-payment loan.

A genuine lease — an "agreement to hire" — works the opposite way. Each rental instalment is treated as a separate supply for GST purposes, with the goods deemed supplied progressively as each payment falls due. GST is claimed payment by payment across the life of the lease, not in one lump sum at the start. IS 22/02 sets out the statutory basis for this split precisely: hire purchase agreements are deemed to take place at the time the agreement is signed under section 9(3)(b) of the GST Act, while an agreement to hire falls under section 9(3)(a), with GST payable across the term each time a payment is due or received.

A finance lease sits in a third position again. Where a finance lease qualifies as a credit contract, GST is generally calculated as 3/23 of the cash price of the leased goods (the standard formula for extracting 15% GST from a GST-inclusive figure), spread over the payments across the lease term — lessors commonly use a straight-line spread for this. If a finance lease doesn't fit neatly into either the hire purchase or agreement-to-hire category — what IRD calls a "third category agreement" — GST defaults to the ordinary time-of-supply rule: the earlier of the invoice being issued or payment being received, which in practice is usually still upfront.

A worked example, using IRD's own figures

IRD's guidance sets out a hire purchase example worth working through in full, because it shows exactly how the cash price, the finance charge and GST interact.

A hire purchase sale has a cash price of $550. It's structured as 36 monthly payments of $23, totalling $828 over the life of the agreement. The gap between the two — $278 — is the finance charge: pure interest for spreading the payments, and it is an exempt supply for GST purposes, meaning no GST applies to that portion at all.

GST only applies to the $550 cash price component. Using IRD's own formula for extracting GST from a GST-inclusive figure — multiply the amount by 3 and divide by 23 — the GST embedded in the cash price works out to:

$550 × 3 ÷ 23 ≈ $71.74

Under the hire purchase rules, the purchaser can claim that entire $71.74 of input tax in the period the agreement is signed, in one go — not spread across 36 months alongside the $23 payments. Had this same asset instead been financed through a genuine operating lease structured as 36 separate rental payments, the GST embedded in each instalment would instead be claimed instalment by instalment as the lease runs, not upfront. Same asset, same rough monthly cash outlay, structurally different GST timing.

What pushes a lease toward finance-lease treatment

Structurally, a lease tends to be treated as a finance lease rather than a genuine operating lease where substantially all the risks and rewards incidental to ownership sit with someone other than the lessor — the lessee is carrying the economic weight of ownership even without holding the title.

IRD's clearest worked example of this comes from a provision aimed at leases of assets used mainly overseas, designed to stop depreciation being claimed in New Zealand on assets a New Zealand taxpayer has no real economic interest in: a lease where the lessee covers all operating, maintenance and insurance costs, and guarantees to pay the lessor $1 million at the end of the lease term, at which point the lessor takes the asset back. The same signals that tipped that case toward finance-lease treatment — heavy residual risk sitting with the lessee, a guaranteed end-of-term payment, a lease term that's a large share of the asset's useful life — are the ones that push an everyday domestic equipment or vehicle lease toward finance-lease classification too.

What lands on the balance sheet

What shows up on the balance sheet, and what that does to any covenant you're carrying, is governed by accounting standards rather than the Income Tax Act or GST Act rules set out above. Confirm the specific treatment for your structure with your accountant before you sign, particularly if a covenant is already in place — the tax answer above doesn't automatically tell you the accounting answer.

Frequently Asked Questions

If I'm on a payments basis for GST, do I really get the full GST deduction upfront on hire purchase? Yes. IRD's QB 23/06 confirms this specifically for payments-basis taxpayers: input tax on a hire purchase agreement is claimable in full in the period the agreement is entered into, before any instalments are paid — the payments-basis restriction that normally applies to other purchases doesn't apply here.

Can I depreciate equipment I'm still paying off under hire purchase? Yes. IRD's general depreciation guidance explicitly includes assets bought under a hire purchase agreement alongside assets you own or lease outright — legal title hasn't transferred yet, but the right to claim depreciation has.

Is the finance charge on my hire purchase agreement GST-taxable? No. The finance charge — the gap between the cash price and the total of all instalments — is treated as an exempt financial service for GST purposes, so no GST applies to that portion.

Does a small piece of equipment even need this analysis? Not necessarily. Assets costing up to $1,000 (for anything acquired from 17 March 2021) can be written off immediately rather than depreciated, which sidesteps most of this comparison entirely for smaller purchases.

Does a finance lease always mean I never own the asset? No. IRD's interpretation statement is specific: a finance lease will not be treated as a simple lease where the lessee is the end user with an option to purchase, or where ownership is contractually certain to pass. Some finance leases are structured to transfer title eventually; others aren't. Check whether your specific agreement includes a purchase option before assuming either way.

Assuming legal title and the right to claim depreciation move together. Under hire purchase, IRD lets you depreciate an asset the supplier still legally owns until the final payment — most generic articles conflate the two and get it wrong.
