Trailer boats, yachts, and commercial marine vessels — compare rates from 7.49%, claim the $20k write-off on commercial vessels, and calculate your exact repayments.
The May 2026 Federal Budget proposes to make the $20,000 instant asset write-off a permanent feature of the tax law. Business vessels under $20,000 (ex-GST) used for charter, fishing or tourism can be fully written off in the year of purchase. Full Budget guide →
Australia has one of the world’s highest rates of recreational boat ownership — over 750,000 registered vessels — backed by a thriving commercial marine sector covering fishing, charter, and tourism. Whether you’re buying your first tinnie, upgrading to an offshore cruiser, or financing a charter vessel for your tourism business, there are structured marine finance options designed for your needs.
Boat finance typically works through a secured marine loan (for private buyers), a chattel mortgage (for commercial or business-use vessels), or a finance lease. The vessel secures the loan in most cases, resulting in significantly lower rates than an unsecured personal loan. For high-value vessels (over $500K), lenders may require a marine survey and proof of commercial operations.

| Feature | Private (Secured Loan) | Commercial (Chattel Mortgage) |
|---|---|---|
| GST credit upfront | No | Yes — claimed on BAS |
| $20k instant write-off eligible | No | Yes (if <$20k ex-GST & commercial use) |
| Depreciation deduction | No | Yes (over effective life of vessel) |
| Interest deductible | No | Yes (business-use portion) |
| Loan term | 1–7 years | 1–15 years (commercial) |
| Survey required? | Sometimes (>$150K or older) | Often required (>$250K) |
A vessel that is primarily used for personal recreation does not qualify for the instant asset write-off or depreciation deductions, even if it occasionally generates income. Where a vessel has genuinely mixed use (recreational plus commercial charter), only the commercial-use percentage of costs is deductible. Keep detailed usage logs and consult your tax adviser before claiming.
The proposed permanent write-off is relevant for the commercial marine sector in Australia. Here’s what qualifies:
A small oyster farm operator purchases a $16,500 aluminium work boat + 60hp outboard for farm servicing (total $16,500 ex-GST):
| Tax Item | Amount |
|---|---|
| GST credit on BAS | $1,650 |
| Instant write-off deduction | $16,500 |
| Tax saving at 27.5% company rate | $4,538 |
| Total Year 1 tax benefit | $6,188 |
| Net cost after tax & GST | $11,962 |
Estimates only. Consult your tax adviser. Always verify with the ATO before claiming.
For larger commercial vessels over $20,000, depreciation applies over the effective life of the asset — typically 10–15 years for commercial vessels under the ATO’s guidelines.

Available for boats from $10,000 to $500K+. Terms from 1–10 years depending on vessel value. No business registration required — any individual with a steady income can apply.
For business operators — charter companies, fishing businesses, aquaculture farms. You own the vessel from settlement, claim GST upfront, and can claim depreciation and interest as business expenses. The most tax-effective option for genuinely commercial vessels.
The lender owns the vessel and leases it to your business. Monthly payments are fully tax-deductible. At the end of the term, pay the residual to take ownership or hand the vessel back. Lower monthly costs than chattel mortgage for the same vessel. Best for businesses wanting predictable operating costs.
| Structure | Ownership | Tax Write-Off | GST | Best For |
|---|---|---|---|---|
| Secured Marine Loan | Immediate | No (private) | No | Private buyers |
| Chattel Mortgage | Immediate | ✅ Yes (commercial) | ✅ Upfront | Commercial operators |
| Finance Lease | At end of term | ❌ No write-off | Monthly | Commercial, lower payments |
