Should you buy that $45,000 compressor outright, finance it on a chattel mortgage, or lease it through an operating lease? The answer depends on how you weigh cash flow, tax treatment, ownership, and the nature of the equipment — and getting it right can save a trade business tens of thousands of dollars over five years.

This guide breaks down the real costs, tax treatment, and practical considerations of buying versus leasing equipment for Australian trade businesses.

The Core Question: Ownership vs Access

The fundamental difference between buying and leasing is about ownership:

Buying (outright or financed): You own the equipment. It's yours to use, modify, depreciate, and eventually sell. You bear the risk of depreciation, technological obsolescence, and maintenance.

Leasing (operating or finance lease): You use the equipment during the lease term. Depending on the lease type, you may or may not own it at the end. The lessor bears some of the obsolescence and residual value risk.

Neither approach is universally superior. The best choice depends on your specific situation.

Types of Equipment Finance and Their Tax Treatment

1. Outright Purchase (Cash)

You pay the full price from business funds or personal savings.

Pros: No interest cost, no debt on the books, full ownership immediately
Cons: Uses up cash reserves, no leverage, ties up capital that could generate returns elsewhere

Tax treatment:

  • You own the asset from day one
  • Claim depreciation over the asset's effective life
  • Under the instant asset write-off (until 30 June 2026, for assets under $20,000), you can claim the full cost immediately
  • For assets over $20,000, depreciate over effective life using diminishing value or prime cost method

2. Chattel Mortgage (Finance Purchase)

You borrow to buy the equipment. You own it from day one, but the lender holds security over it.

Pros: You own the asset immediately, claim GST on the purchase price (next BAS), claim interest as a deduction, flexibility to sell if needed
Cons: Interest cost, debt on the balance sheet, you bear all depreciation risk

Tax treatment:

  • Claim GST upfront on the full purchase price (if GST-registered) — major cash flow benefit
  • Claim depreciation (same as outright purchase)
  • Claim interest on the loan as a deductible business expense each year
  • Interest is NOT deductible in a finance lease — depreciation is. With a chattel mortgage, BOTH are deductible

3. Finance Lease (Equipment Lease to Own)

The lessor (finance company) owns the equipment. You use it and make periodic payments. At the end of the lease, you typically have the option to purchase the asset at a residual value (balloon payment).

Pros: Lower upfront cash required, payments are predictable
Cons: You don't own the asset during the lease, GST treatment is different (paid on each lease payment, not upfront), higher total cost than chattel mortgage in many cases

Tax treatment:

  • Claim lease payments as deductions (each payment, not depreciation)
  • Claim GST on each payment (not upfront on the full purchase price)
  • Cannot claim depreciation as you don't own the asset
  • At lease end, if you purchase the asset, you then own it and can depreciate

4. Operating Lease (True Lease, No Ownership)

A true operating lease means you use the equipment for the lease period and return it at the end — no option to buy. Common for specialised equipment, vehicles, and technology.

Pros: No ownership risk, no residual value risk, latest equipment available, fully deductible rental payments, off-balance-sheet (simpler for sole traders)
Cons: No ownership, potentially higher per-period cost than owning, no asset at end, may have usage restrictions

Tax treatment:

  • Lease payments are fully deductible as operating expenses
  • No depreciation claim (you don't own it)
  • No GST upfront — GST on each payment
  • At lease end, you return the equipment or negotiate a new lease

5. Rent (Equipment Hire)

Short-term hire from an equipment rental company — daily, weekly, or monthly rates.

Pros: Maximum flexibility, no commitment, no maintenance responsibility
Cons: Most expensive per unit of time, not always available, unsuitable for ongoing needs

Tax treatment:

  • Hire costs are fully deductible as expenses
  • GST on each hire payment

A Real-World Cost Comparison: $60,000 Compressor

Let's compare three options for a sole trader tradie needing a $60,000 (ex-GST) air compressor:

Option A: Chattel Mortgage

  • Loan: $60,000 at 8% p.a. over 5 years
  • Monthly payment: approximately $1,217
  • Total paid: $73,020
  • GST claimed upfront: $6,000 (next BAS)
  • Interest deductible: approximately $13,020 over 5 years
  • Depreciation deductible: $60,000 over effective life (say 10 years at 20% diminishing)
  • Own at end: Yes

After-tax cost (at 32.5% marginal rate, including GST and deductions): Total outlay: $73,020 Less GST refund: -$6,000 Less tax saving on interest ($13,020 × 32.5%): -$4,232 Less tax saving on depreciation (simplified): -$9,750 (rough estimate over life) Net real cost: approximately $53,038

Option B: Operating Lease

  • Lease payment: $1,400/month for 5 years (indicative)
  • Total paid: $84,000
  • All lease payments tax deductible at 32.5%: $84,000 × 32.5% = $27,300 in tax savings
  • Own at end: No — return the compressor

Net real cost: approximately $56,700

Option C: Outright Purchase

  • Pay $60,000 cash (plus $6,000 GST = $66,000 total)
  • GST claimed back: -$6,000
  • Depreciation deductions over life: reduces taxable income (simplified value: ~$9,750 at 32.5%)
  • No interest cost
  • Net real cost: approximately $50,250

Own at end: Yes — and the compressor still has residual value

Comparison Summary

  • Cash purchase — $66,000 — GST + depreciation — ~$50,250 — Yes
  • Chattel mortgage — $73,020 — GST + depreciation + interest — ~$53,038 — Yes
  • Operating lease — $84,000 — Lease payments — ~$56,700 — No

Caveat: These are simplified estimates. Your actual tax benefit depends on your marginal rate, cash flow timing, and specific loan/lease terms. An accountant can run the exact numbers for your situation.

When Leasing Makes Sense for Tradies

Despite costing more in straight dollar terms in many cases, leasing can be the smarter choice in specific situations:

1. Equipment That Becomes Obsolete Quickly

Technology equipment — laser levels, diagnostic tools, drones, digital measuring devices — may need replacement every 3–4 years as the technology advances. An operating lease keeps you current without being stuck with outdated owned equipment.

2. Specialist Equipment for Specific Projects

If you need a specialised attachment or machine for a one-off contract, a short-term operating lease or hire is far more sensible than buying. Hire the cost into the job quote, complete the contract, return the equipment.

3. Cash Flow Preservation

If buying equipment outright would deplete your business cash buffer below comfortable levels, a chattel mortgage or operating lease preserves cash. The interest cost is the price of that cash preservation.

4. Businesses in Rapid Growth Phase

Growing trade businesses often need equipment but also need capital for wages, materials, and working capital. Leasing spreads the cost of equipment over the period you're using it — matching the cost to the revenue generated.

5. Equipment You're Unsure About

If you're uncertain whether a specific piece of equipment will suit your workflow, a trial lease for 6–12 months before committing to purchase is sensible risk management.

When Buying is Better

1. Core Equipment You'll Use for 10+ Years

Your primary ute, trailer, compressor, or scaffolding system will be used for the life of your business. Owning this equipment eliminates ongoing lease costs and builds equity. At end of life, even salvage or resale value is yours.

2. The Instant Asset Write-Off Window (Until 30 June 2026)

For assets under $20,000, the instant write-off allows a full deduction in year one. If you buy a $15,000 set of tools cash and write them off immediately, the tax saving at 32.5% is $4,875 — in the same year. A lease doesn't deliver this front-loaded benefit.

3. When Financing Rates Are Reasonable

If you can secure a chattel mortgage at 7–8% p.a. and the equipment will generate significantly more than this cost, buying on finance is sensible. The tax deductions on interest and depreciation further reduce the net cost.

4. When You Want to Build Business Asset Value

If you're planning to sell your business eventually, owned equipment appears on your balance sheet and potentially contributes to business value. Leased equipment doesn't.

The GST Timing Difference — Often the Deciding Factor

For GST-registered tradies, the difference in GST treatment between a chattel mortgage and a finance lease or operating lease can be significant:

Chattel mortgage: Claim the full GST (1/11th of purchase price) on your next BAS. On a $60,000 purchase, that's $5,454 back on your next BAS.

Operating lease or finance lease: GST is claimed on each payment. The total GST claimed over the lease term is the same, but it's spread over 60 months instead of being a lump sum.

For a business that's tight on cash, the chattel mortgage's upfront GST refund can meaningfully improve cash flow.

Questions to Ask Before Deciding

  1. How long will I use this equipment? Under 2 years: consider hire/lease. 5+ years: buy.

  2. Do I have the cash or credit capacity? Tight cash: lease. Healthy cash reserve: buy or finance at good rate.

  3. Is the equipment at risk of obsolescence? Technology equipment: lean toward lease. Heavy equipment: buy.

  4. What's my marginal tax rate? Higher marginal rates = more valuable deductions = more benefit from the tax-deductible purchase options.

  5. Am I in the instant asset write-off window? Under $20,000 assets before 30 June 2026 = strong argument for buying.

  6. Do I want flexibility to upgrade or modify? Modifying leased equipment is often restricted. Owned equipment is yours to adapt.

Comparison Quick Reference

  • Core tool used daily, 10+ years — Buy (cash or chattel mortgage) — Lowest net cost over time
  • Short-term project only — Hire — Pay-as-you-need
  • Fast-obsolescence tech — Operating lease — Upgrade flexibility
  • Need to preserve cash — Chattel mortgage or lease — Spread cost
  • Under $20,000, before June 2026 — Buy — Instant write-off benefit
  • Uncertain about the equipment — Short-term lease then buy — Trial before commitment

Frequently Asked Questions

Q: Can I claim GST on a lease?
Yes, but differently. On an operating or finance lease, you claim GST on each periodic payment (monthly or quarterly), not upfront. On a chattel mortgage or outright purchase, you claim all the GST on the next BAS after purchase.

Q: Does leasing affect my borrowing capacity for a home loan?
Yes. Both finance lease obligations and operating lease payments are considered financial commitments by lenders when assessing home loan serviceability. Chattel mortgage repayments also count. Owning equipment outright (cash purchase) has no ongoing commitment to affect borrowing capacity.

Q: What happens at the end of an operating lease?
You return the equipment, or you negotiate to extend the lease or purchase at market value. If the equipment has maintained value and you want to buy, your negotiating position at end-of-lease can be strong — especially if you've maintained it well.

Q: Can I refinance from a finance lease to a chattel mortgage?
Not typically mid-term without penalty. At end-of-lease, if you want to purchase the asset, you effectively "buy" at the residual value — which you could then refinance under a chattel mortgage. Speak to a finance broker about the options.
