Do you know how trailer finance actually works?

Most trailer purchases for business use get financed the same way you'd fund a truck or excavator.

Whether you're adding a single box trailer to your setup or putting together a small fleet of car carriers, the structure usually involves a chattel mortgage or hire purchase arrangement. Both let you claim depreciation and GST, but the way they affect your cashflow and balance sheet differs enough that choosing the wrong one can cost you several thousand dollars over the term.

Chattel mortgage vs hire purchase for trailers

A chattel mortgage lets you own the trailer from day one, while hire purchase transfers ownership after the final payment. Under a chattel mortgage, the lender takes security over the trailer but you're the registered owner immediately, which means you claim depreciation from the start and can usually reclaim the GST on the purchase price upfront if you're registered. With hire purchase, ownership sits with the lender until the term ends, so you claim a tax deduction on each repayment instead of depreciating the asset yourself.

Consider a landscaping business buying a $35,000 tandem axle trailer with ramps. Under a chattel mortgage with a five-year term and a 20% balloon payment, the business pays roughly $550 per month, claims the full depreciation each year, and gets the GST back in the next BAS. The same trailer under hire purchase might have similar monthly repayments, but the business claims the repayments as an expense rather than owning and depreciating the asset. For most operators with an accountant who's across depreciation schedules, the chattel mortgage delivers better cashflow because of the upfront GST treatment.

How balloon payments affect trailer finance

A balloon payment reduces your monthly repayment by deferring a lump sum to the end of the term. Lenders typically allow balloons of up to 50% on commercial vehicle finance, though 20% to 30% is more common for trailers because resale values can shift depending on condition and market demand.

If you set a $10,000 balloon on a $30,000 trailer over four years, your monthly repayment drops by around $200 compared to paying the full amount across the term. At the end, you either pay the balloon in cash, refinance it, or sell the trailer and settle the balance. The third option works well if you've maintained the trailer and the market hasn't dropped, but if resale values have softened or the trailer's taken a beating, you might end up covering the shortfall out of working capital.

GST treatment on trailer purchases

For GST-registered businesses, a chattel mortgage lets you claim the GST on the trailer's purchase price in your next Business Activity Statement, assuming the seller charged GST. That means a $33,000 trailer including GST gives you a $3,000 credit almost immediately, which improves cashflow in the first quarter. Hire purchase structures the GST differently because you're technically renting the trailer until the final payment, so the GST component gets spread across each repayment rather than claimed upfront.

In our experience, operators who run tight cashflow prefer the upfront GST claim because it offsets some of the deposit and associated costs. If you're buying a car trailer for $40,000 including GST and putting down a 20% deposit, reclaiming the GST within a month or two can bring that initial outlay down considerably.

Finance lease vs chattel mortgage for trailer fleets

A finance lease treats the trailer as an off-balance-sheet expense, which can suit businesses that need to preserve reported assets or meet certain financial covenants with other lenders. You make regular payments over the term, claim those payments as a tax deduction, and either return the trailer, pay a residual to keep it, or refinance at the end. The lease structure means you don't own the trailer during the term, so depreciation stays with the lessor, but your repayments are fully deductible as an operating expense.

For a three-trailer fleet valued at $90,000, a finance lease might make sense if your business is applying for additional working capital and wants to keep equipment debt off the balance sheet. The downside is you lose the upfront GST claim and don't benefit from depreciation, which can reduce the overall tax efficiency compared to a chattel mortgage. Most transport and logistics businesses stick with chattel mortgages unless their accountant has flagged a specific reason to lease.

How lenders assess trailer finance applications

Lenders look at your business financials, time in operation, and the type of trailer you're buying. A two-year-old enclosed trailer from a known brand will usually attract better rates than a fifteen-year-old flat-top with custom modifications, because resale is more predictable. If your business has been trading for less than two years, some lenders will ask for additional information like BAS statements or bank statements showing consistent revenue, while established businesses with solid financials can often get approved with minimal paperwork.

Deposit requirements vary, but 20% is common for trailers under $50,000. Some lenders will go lower if the trailer is new and the business financials are solid, while others hold firm at 20% regardless. Vendor finance through the dealer can sometimes reduce the deposit requirement, but the interest rate often sits higher than what you'd get through a broker accessing multiple lenders.

When vendor finance makes sense for trailers

Vendor finance is an arrangement where the dealer provides the funding directly, often with a faster approval process and lower deposit. It works well if you need the trailer immediately and don't have time to compare lenders, or if your business financials are still building and a mainstream lender has declined. The trade-off is usually a higher interest rate, sometimes by one or two percentage points, and less flexibility around term length and balloon options.

If you're buying a $25,000 box trailer and the dealer offers vendor finance at 8.5% with a 10% deposit, that might cost you an extra $2,000 over a five-year term compared to a chattel mortgage at 7% through a broker. For some operators, the speed and convenience justify the cost. For others, waiting a few days for a lower rate through a broader panel of lenders makes more sense.

Using trailer finance to preserve working capital

Funding a trailer instead of paying cash keeps your working capital available for stock, wages, and unexpected costs. A $40,000 trailer purchased outright drains that amount from your business account immediately, while financing it with a 20% deposit leaves $32,000 in the bank. Over a five-year term, the interest cost might add $6,000 to $8,000 depending on the rate and balloon, but that's often worth it if the alternative is running low on operating funds during a slow month.

This approach is particularly relevant for businesses in seasonal industries like landscaping or agriculture, where cashflow fluctuates throughout the year. Keeping capital on hand means you can cover payroll and supplier invoices without relying on an overdraft or director's loan when income dips.
