7 Tax Deduction Factors in Asset Finance Australia

Written by Colin Evans | Aug 9, 2026, 11:03:14 AM

Asset finance can help Australian businesses purchase vehicles, machinery and equipment while keeping more working capital available for day-to-day operations. The finance structure can also affect when the business owns the asset, how repayments are treated and which deductions may be available.

The Asset Finance Shop (TAFS) primarily arranges chattel mortgage finance for trucks, commercial vehicles, machinery and other income-producing business assets. Under a chattel mortgage, the business owns the asset from settlement while the lender registers a security interest over it until the finance is repaid.

Tax outcomes depend on the business structure, GST registration, accounting method, asset type and percentage of business use. The following tax deduction strategies can help business owners ask better questions before selecting a finance structure.

1. Separate the Asset Purchase From the Loan Repayments

A common mistake is assuming the full chattel mortgage repayment is tax deductible.

Each repayment generally contains two components:

  • Principal, which reduces the amount borrowed
  • Interest, which is the cost of the finance

The principal component is generally not claimed as an immediate operating expense. The asset’s cost is usually dealt with through depreciation, simplified depreciation rules or another available capital allowance.

 

Your accountant can separate the principal and interest components using the loan schedule supplied by the lender.

2. Understand How a Chattel Mortgage Affects Ownership

The main finance product TAFS arranges for equipment and commercial vehicles is a chattel mortgage.

Under this structure:

  • The business owns the asset from settlement
  • The lender registers a security interest over it
  • The business makes repayments over an agreed term
  • A balloon payment may be included
  • The lender’s security is removed after the finance is repaid

Because the business owns the asset, it can generally claim eligible deductions relating to the decline in value of the business-use portion. The exact depreciation method will depend on the business and the tax rules that apply.

This differs from a rental or lease arrangement where the provider generally owns the asset and the business pays for its use. The tax treatment of those payments can differ from a chattel mortgage.

TAFS primarily arranges chattel mortgage finance rather than rent-to-own or equipment rental products. However, we provide all products that suit a client’s unique requirements.

3. Claim Only the Business-Use Portion

A vehicle or piece of equipment may be used for both business and private purposes.

Only the business-use portion of eligible expenses can generally be claimed.

For example, if a vehicle is used 80% for business and 20% privately, the business may need to limit its claims to the eligible business portion.

Expenses that may need to be apportioned include:

  • Interest
  • Depreciation
  • Fuel
  • Registration
  • Insurance
  • Repairs
  • Servicing
  • Tyres
  • Lease or rental costs, where relevant

The method used to calculate business use can depend on the business structure and the type of vehicle. Records may include logbooks, odometer readings, invoices and details of business and private travel.

Machinery used entirely within the business may have a clearer business-use percentage, but the business should still keep records showing how the asset supports income-producing activities.

4. Check Whether the Instant Asset Write-Off Applies

Eligible small businesses may be able to use the instant asset write-off for qualifying assets that cost less than the applicable threshold.

From 1 July 2026, the Australian Government announced a permanent $20,000 instant asset write-off threshold for eligible small businesses. Eligibility depends on factors including aggregated turnover, the asset’s cost and when it is first used or installed ready for business use.

The threshold applies to each individual asset, rather than the total value of all equipment purchased.

It can apply to eligible:

  • New assets
  • Second-hand assets
  • Tools
  • Smaller equipment
  • Technology
  • Machinery
  • Business vehicles below the relevant threshold

An asset that costs the same as or more than the threshold may need to be depreciated or added to the small business pool rather than written off immediately.

Financing the asset doesn’t automatically prevent the business from qualifying. The relevant issue is generally the asset, business eligibility and tax treatment, rather than whether the purchase was paid for upfront or through a chattel mortgage.

The instant asset write-off rules have changed over time, so confirm the current threshold and eligibility with your accountant before relying on an immediate deduction.

5. Consider Depreciation Before Choosing the Asset

Most larger vehicles and equipment will cost more than the instant asset write-off threshold.

These assets are generally claimed over time through depreciation or simplified depreciation rules.

Depreciation recognises that an income-producing asset loses value as it is used. The available deduction can depend on:

  • Purchase price
  • Date first used
  • Business-use percentage
  • Effective life
  • Depreciation method
  • Business structure
  • Whether simplified depreciation applies
  • Whether the asset is later sold or traded

Eligible small businesses using simplified depreciation generally add higher-cost assets to the small business pool. The ATO currently describes a 15% deduction in the year the asset is first used or installed ready for use, followed by a 30% deduction in later years, subject to the applicable rules.

Before buying, ask your accountant how the asset is likely to be depreciated and when the first deduction can be claimed.

6. Check the GST Treatment Before Settlement

A GST-registered business may be able to claim a GST credit on the business-use portion of an eligible asset purchase.

Under a chattel mortgage, the business purchases the asset and owns it from settlement. The GST treatment is linked to the purchase rather than the principal portion of each loan repayment.

The available GST credit can depend on:

  • Whether the business is registered for GST
  • Whether the seller charges GST
  • Whether a valid tax invoice is available
  • The percentage of business use
  • The business’s GST accounting method
  • Whether the asset is subject to a limit
  • Whether the purchase is from a private seller

A private seller may not be registered for GST. In that situation, the purchase price may not include a GST amount for the buyer to claim.

Passenger vehicles can also be subject to a car limit. For vehicles first used or leased in the 2026 to 2027 financial year, the car depreciation limit is $69,883. The maximum GST credit on certain vehicles can also be limited by this threshold, subject to exceptions.

Commercial trucks and vehicles designed to carry heavier loads may be treated differently from passenger cars. Your accountant can confirm whether a particular vehicle is subject to the car limit.

7. Structure the Term and Balloon Around the Business, Not Just Tax

Tax benefits should support the purchase decision, but they shouldn’t be the only reason for choosing a finance structure.

A chattel mortgage can usually be structured with:

  • A deposit
  • An agreed loan term
  • Regular repayments
  • A trade-in
  • A balloon payment

A larger balloon can reduce regular repayments because part of the principal remains outstanding until the end of the term.

However, a balloon doesn’t create an additional deduction by itself. It changes the timing of the principal repayments and may affect the total interest paid.

Before selecting a balloon, consider:

  • Expected asset value at the end of the term
  • How long the business plans to keep the asset
  • Annual usage
  • Maintenance costs
  • Replacement plans
  • Trade-in value
  • Ability to pay the final amount
  • Whether refinancing may be required

The term should also suit the asset’s working life. Lower repayments may not help if the business is still paying for an ageing truck or machine when it needs to be replaced.

The strongest financial structuring usually balances tax planning with cash flow, asset life and the total finance cost.

How Common Finance Structures Can Affect Tax Treatment

Different equipment financing options can produce different ownership and tax outcomes.

Finance structure

Who generally owns the asset during the term?

Common tax considerations

Chattel mortgage

The business

Eligible interest and depreciation may be claimed for the business-use portion. A GST credit may also be available where the requirements are met.

Hire purchase

The finance provider generally owns it until the final payment

GST, interest and depreciation treatment depends on the agreement and the business’s circumstances.

Equipment lease or rental

The finance or rental provider

Eligible rental or lease payments may be deductible to the extent the equipment is used for business.

Outright purchase

The business

The business may claim depreciation, an immediate deduction where eligible and the business-use portion of running costs.

TAFS primarily arranges chattel mortgage finance. Speak with an accountant before comparing structures based on tax outcomes alone.

What Expenses May Be Deductible on a Business Vehicle?

Depending on the vehicle and how it is used, eligible deductions can include the business-use portion of:

  • Interest on the vehicle finance
  • Depreciation
  • Fuel
  • Registration
  • Insurance
  • Repairs
  • Servicing
  • Tyres
  • Tolls
  • Parking
  • Cleaning
  • Other operating costs

The business needs records to support the claim. These may include loan documents, tax invoices, registration papers, receipts, logbooks and kilometres travelled for business and private use.

Fines and private expenses aren’t generally deductible.

What Expenses May Be Deductible on Machinery and Equipment?

For eligible business machinery and equipment, potential deductions can include:

  • Interest on the finance
  • Depreciation or decline in value
  • Repairs and maintenance
  • Insurance
  • Fuel and energy costs
  • Consumables
  • Registration, where applicable
  • Transport and installation costs, depending on their treatment
  • Eligible operating expenses

Some costs may form part of the asset’s cost base rather than being claimed immediately.

For example, delivery, installation or modifications required before the asset can be used may need to be included in the asset’s value for depreciation purposes.

Your accountant can determine whether a cost is immediately deductible, depreciated over time or treated in another way.

Does a Deposit Create a Tax Deduction?

A deposit reduces the amount that needs to be financed.

It doesn’t generally create a separate deduction simply because the business contributed cash upfront.

The tax treatment is connected to the asset purchase and eligible business costs, rather than whether the purchase was funded through:

  • A deposit
  • A trade-in
  • A loan
  • Existing business cash
  • A combination of these sources

A larger deposit can reduce the loan amount, repayments and total interest paid.

A smaller deposit can preserve working capital but may increase the amount financed.

The decision should consider cash flow and finance cost as well as tax planning.

Does a Balloon Payment Change Depreciation?

A balloon payment generally doesn’t change the purchase price of the asset or the depreciation method applied to it.

The balloon affects the finance structure, not the underlying cost of the vehicle or equipment.

A larger balloon can:

  • Reduce regular repayments
  • Leave more principal outstanding
  • Increase the final payment
  • Increase total interest in some cases
  • Affect future trade-in or refinance decisions

The asset’s tax treatment should be assessed separately from the loan repayment structure.

Can Used Equipment Receive the Same Tax Benefits as New Equipment?

Used business equipment may still qualify for:

  • Depreciation
  • Simplified depreciation
  • The instant asset write-off, where eligible
  • Eligible interest deductions
  • Business operating expense deductions

The instant asset write-off can apply to eligible new and second-hand assets.

The GST treatment may differ depending on the seller.

A GST-registered dealer may provide a tax invoice showing GST. A private seller who isn’t registered for GST generally won’t charge GST, which can mean there is no GST credit available to the buyer.

This should be considered when comparing dealer and private-sale prices.

Records to Keep for Asset Finance Tax Claims

Good recordkeeping helps the business and its accountant calculate eligible deductions correctly.

Keep copies of:

  • Finance contracts
  • Loan repayment schedules
  • Tax invoices
  • Settlement statements
  • Deposit receipts
  • Trade-in documents
  • Registration papers
  • Insurance documents
  • Fuel and maintenance receipts
  • Repair invoices
  • Logbooks
  • Odometer records
  • Equipment usage records
  • Private-sale agreements
  • Asset disposal and payout documents

Records should clearly show the asset, purchase date, purchase price, finance amount and business use.

When the asset is sold or traded, keep the sale invoice, payout letter and settlement records because the disposal may affect the business’s depreciation calculations.

Questions to Ask Your Accountant Before Financing an Asset

Before purchasing a vehicle or piece of equipment, ask:

  1. What percentage of the asset will be used for business?
  2. Can the business claim a GST credit?
  3. Does the car limit apply?
  4. Is the asset eligible for the instant asset write-off?
  5. Will the asset be depreciated individually or through a small business pool?
  6. When can depreciation begin?
  7. How will the interest component be claimed?
  8. What records should the business keep?
  9. Will a trade-in create a tax adjustment?
  10. How will a future sale affect the business?
  11. Does the business structure change the available deduction method?
  12. Are there any private-use or fringe benefits tax considerations?

Discussing these questions before settlement can help avoid incorrect assumptions about the tax benefits of the finance.

Frequently Asked Questions

Is a Chattel Mortgage Tax Deductible?
