Lease vs Buy: How to Decide What's Right for Your Business

Everyone asks lease or buy. Almost nobody asks the right follow-up questions. They compare monthly repayments, pick the lower number, and move on. Then three years later they're stuck in a structure that doesn't fit their business anymore, and the exit costs more than the difference they saved.

Equipment finance funds a substantial share of capital expenditure for Australian businesses. This isn't a niche decision. It's one of the most common financial choices a business owner makes. And the structure matters as much as the rate.

The question isn't "lease or buy." It's "what happens next."

Monthly repayments are the easy part. The real differences between a chattel mortgage and a finance lease show up in three places: your tax return, your cash flow in year one, and what happens when your plans change mid-term.

Neither structure is better. They solve different problems. Here's how to tell which problem is yours.

Chattel mortgage: ownership from day one

A chattel mortgage is the most popular equipment finance structure in Australia. You take ownership of the asset immediately. The lender holds a mortgage over it as security, but it's yours on your balance sheet from settlement.

The tax treatment is front-loaded. If you're GST-registered, you claim the full GST credit on the purchase price upfront. On a $150,000 excavator, that's roughly $13,600 back in your next BAS. You also claim depreciation each year, plus the interest component of your repayments as deductions.

As at April 2026, rates for established businesses sit around 5.5% to 8% p.a. on standard assets. Newer businesses or specialist equipment push higher, sometimes 10-14%.

The trade-off is higher monthly repayments. On a $100,000 asset at 8% over five years with no residual, that's roughly $2,030 per month. You're paying down the full principal. For a business with tight monthly cash flow or seasonal revenue dips, that higher fixed commitment can create pressure in quieter months.

But ownership is valuable for one reason: flexibility on exit. If your plans change at year three, you pay out the balance and sell the asset at market value. Most chattel mortgages charge an early repayment fee, but you're selling a real asset you own. The maths usually works.

The other risk is depreciation. You own the asset, which means you wear the full loss in value. If the market moves, or the equipment becomes obsolete faster than expected, you're holding a depreciating asset that's harder to move than you planned.

Finance lease: flexibility built into the structure

A finance lease keeps the asset with the lender. You pay to use it. At the end of the term, you choose: purchase at the residual value, hand it back, or refinance into something newer.

Monthly cost is lower because you're not paying down the full amount. That same $100,000 asset at 8% over five years with a 30% residual drops to roughly $1,490 per month. That's $540 less each month. For a business managing cash flow through a growth phase, a seasonal dip, or a period of investment in other areas, that difference is real money every month.

Tax treatment is different. You can't claim depreciation because the lender owns the asset, but the lease payments themselves are generally deductible. GST is claimed progressively on each payment rather than as a lump sum upfront. For some businesses, that smoother, more predictable deduction profile is actually easier to manage than the front-loaded chattel mortgage approach.

The real advantage is optionality at term end. If you're in an industry where equipment moves fast (medical, IT, certain construction plant), a lease means you're never stuck with yesterday's technology. Hand it back, sign a new lease on the latest model, and your business stays current without funding the gap between what the old asset is worth and what the new one costs.

The trade-off is less flexibility mid-term. If you need out before the lease ends, you're typically liable for the remaining payments plus the residual. That exit cost is higher than a chattel mortgage payout in most cases. Leasing works best when you're confident about the term length.

Your business structure changes the answer

Most business owners know the tax treatment differs between a lease and a chattel mortgage. Fewer realise how much their business structure shifts the numbers. It matters more than most owners expect, and knowing why tells you what to ask your accountant.

Take a $65,000 ute financed via chattel mortgage at 7% over five years. In year one, depreciation on the diminishing value method is roughly $16,250. Interest is roughly $4,550.

If you're a sole trader earning $120,000, your marginal rate is 30% (plus 2% Medicare levy). Those deductions save you about $6,650 in year one. Add the $5,900 GST credit and you're roughly $12,550 ahead before you've made your sixth repayment.

If the same ute sits inside a Pty Ltd company paying the 25% small business rate, the depreciation and interest deductions save about $5,200 in year one. Same GST credit. Total: roughly $11,100.

Same asset. Same price. Same finance structure. Different business entity. $1,450 difference in year one alone.

On a finance lease, neither structure gets the depreciation deduction. Both claim the payments, but the benefit is spread evenly across the term rather than front-loaded. For businesses that want the biggest tax hit in year one, chattel mortgage wins. For businesses that want predictable, level deductions each year, the lease profile is simpler and easier to forecast.

Trusts add another layer. How deductions flow depends on distribution decisions, GST registration of the trust itself, and how the asset is used. This genuinely is one for the accountant.

The traps on both sides

Total cost is closer than you think. Over five years, the total outlay on a chattel mortgage vs a finance lease on the same asset is often within a few hundred dollars. The difference isn't price. It's timing, tax treatment, and optionality. Don't choose based on total cost. Choose based on which profile fits your business.

Residuals aren't free money. A 30% residual on a $100,000 asset means $30,000 due at term end. If you can't comfortably fund that from cash or refinance, a lower residual or no residual might be smarter even if the monthly cost is higher.

Ownership isn't always an advantage. Buying a $90,000 piece of plant equipment that's worth $35,000 three years later means you're carrying $55,000 in depreciation on your books. If you'd leased it, you'd hand it back and let the lender wear that loss. In fast-depreciating asset categories, ownership is a risk, not just a benefit.

Match the term to the asset's useful life. Financing a vehicle over seven years when you'll replace it in four creates problems on either structure. On a chattel mortgage, you're selling an asset mid-loan. On a lease, you're paying out early. Get the term right from the start.

Used assets are harder to lease. Lenders are more cautious with finance leases on second-hand equipment because the residual value is less predictable. If you're buying used, a chattel mortgage is often the smoother path.

How to make the call

Talk to your accountant first. Not after. Before. Tell them the asset, the approximate cost, and your business structure. Ask specifically: "Given my tax position this year, would I be better off with a chattel mortgage or a finance lease?" The answer depends on things only they can see.

Model the total picture, not the monthly number. Compare total cost over the full term, tax benefits in year one vs spread over the term, the residual obligation, and the exit cost if your plans change at year three. A broker can run both structures side by side across multiple lenders.

Be honest about your timeline. If you'll keep the asset long-term and you value the flexibility to sell whenever you want, ownership via chattel mortgage is the stronger fit. If you upgrade regularly, want lower monthly commitments, or need to keep assets off the balance sheet, a finance lease is built for exactly that.
