The short answer
Trailer finance is a business loan or lease used to buy a trailer, from a plant or tag trailer to a tipper, refrigerated van, curtainsider or B-double set, with the trailer as the lender's security. Trailers can be financed on their own or packaged with the truck that tows them. Because heavy trailers have fewer moving parts and a longer working life than trucks, lenders often allow longer terms and older age limits for them. The tax rules recognise the difference too. Trailers with a gross vehicle mass over 4.5 tonnes have a capped effective life of 10 years, compared with 7.5 years for trucks (ATO). Most trailer deals are written as a chattel mortgage over three to seven years. Specialised trailers such as tankers or refrigerated vans are financeable but have a narrower resale market, so lenders may ask for a valuation. Small trailers can fall under the instant asset write-off.
Which trailers can be financed?
- Light trailers: box, car carrier and small plant trailers.
- Plant, tag and float trailers for moving excavators, loaders and rollers.
- Tipper trailers, including dog and pig trailers behind a tipper truck.
- Semi-trailers: flat tops, drop decks, curtainsiders, refrigerated vans and skels.
- Specialised equipment: low loaders, extendables, tankers and livestock crates.
- Multi-trailer combinations such as B-double sets.
How is trailer finance different from truck finance?
A trailer has no engine or gearbox and wears more slowly, so a well-built trailer can work for decades. Lenders reflect that with longer terms and more relaxed age limits than they apply to prime movers. The ATO's statutory caps show the same gap: 10 years for trailers over 4.5 tonnes GVM, against 7.5 years for trucks over 3.5 tonnes.
The longer life changes the maths. Assuming 9% a year, a $45,000 trailer costs about $934 a month over five years and about $724 a month over seven. The longer term costs more interest in total, roughly $15,800 against $11,000, but frees up monthly cash flow while the trailer keeps earning.

Should the trailer be financed with the truck?
Packaging the truck and trailer together means one application, one approval and one settlement. Separate contracts let each asset run on its own term, so the trailer can be financed for longer, and they make it easier to sell or replace one without disturbing the other. Your broker can structure it either way.
What do lenders look at?
- Build quality and make. Trailers from established builders with service histories are easiest.
- Specialisation. A standard flat top or curtainsider has a deep resale market. A tanker or a refrigerated van with a particular unit has fewer buyers, so a valuation may be needed.
- The work. Contracts, regular customers and the truck that will tow it.
- Your trading and credit, as with any asset finance.
Small trailers and the instant asset write-off
Box and small plant trailers often cost under $20,000. Businesses with aggregated turnover under $10 million may be able to deduct the full cost of an asset under that limit in the year it's first used. Many lenders also have a minimum loan size, so a small trailer is often better added to a larger vehicle deal or paid in cash.
Example scenario
A tipper operator with a three-year-old truck adds a dog trailer to double the load per trip. The broker places the $85,000 trailer on a separate seven-year chattel mortgage, keeping its repayment low, and leaves the truck's existing finance in place. A quarry contract supports the extra capacity.
