## Post #1 by @MyCarTracks_support

Self-employed car expenses in Australia depend first on your business structure and vehicle type. This guide helps you choose the right deduction method before you start the tax calculation. The [ATO motor vehicle expense calculation methods](https://www.ato.gov.au/businesses-and-organisations/income-deductions-and-concessions/income-and-deductions-for-business/deductions/deductions-for-motor-vehicle-expenses/motor-vehicle-expense-calculation-methods) guidance says sole traders and eligible partnerships can use cents per kilometre or logbook for cars, while other vehicles, companies, and trusts use actual costs.

For a sole trader or partnership using a car, cents per kilometre is simpler and capped at 5,000 business kilometres per car, per income year. The logbook method takes more recordkeeping, but it can support a larger claim when business use or actual running costs are high. If you use the vehicle privately as well as for business, only the business portion is deductible.

This article is educational and is not tax, legal, payroll, employment, or financial advice. Australian rules can change by income year, business structure, vehicle type, GST position, employer payment, and fringe benefits tax treatment. Check current ATO guidance and a qualified professional before relying on a claim.

## Quick answer

Self-employed Australians usually claim business car expenses by choosing the ATO method that matches the vehicle and structure. A sole trader or eligible partnership using a car can usually choose cents per kilometre or logbook. A company or trust, or a sole trader or partnership using a non-car vehicle such as a motorcycle, large van, ute, or truck, uses actual costs. Keep mileage tracking records, receipts, and calculation notes so private use is excluded.

## Who this guide is for

Use this guide if you run business activity as:

- a sole trader
- a contractor or gig worker operating as a sole trader
- a partner in a partnership where at least one partner is an individual
- a small business owner comparing car and non-car vehicle records
- someone who has both employment income and self-employed business activity

If you are also an employee, keep separate records for employment trips and business trips. A trip for your sole trader work and a trip for your job may be recorded in the same app or logbook, but the reports should separate the activity, payment, and tax-return context.

## Self-employed car expenses by structure and vehicle

The method choice is narrower than "pick any method." Start with business structure, then vehicle type.

| Business and vehicle situation | Method to use | Record focus |
| --- | --- | --- |
| Sole trader using a car | Cents per kilometre or logbook | Business kilometres, ownership/lease evidence, logbook records if using actual expenses |
| Partnership using a car, with at least one individual partner | Cents per kilometre or logbook | Business kilometres, partnership records, logbook records if using the logbook method |
| Sole trader or partnership using a motorcycle, truck, large van, ute with one tonne or more carrying capacity, or minibus | Actual costs | Receipts and records that separate business and private use |
| Company or trust using any motor vehicle | Actual costs | Receipts, tax invoices, registration, finance or lease records, and business/private use support |
| Business vehicle available for private use by an employee or associate | Actual costs plus possible FBT analysis | Vehicle availability, private-use records, FBT records, and reimbursement/payment records |

A car is generally a motor vehicle designed to carry less than one tonne and fewer than nine passengers, including the driver. Some utes and vans are cars; others are not. The classification matters because it changes the method.

## What expenses can be deductible?

For business motor vehicle use, common deductible expense categories include:

- fuel and oil
- electricity for charging an electric vehicle
- repairs and servicing
- tyres and maintenance
- insurance
- registration
- eligible finance interest
- vehicle lease payments
- decline in value where the method allows it
- business tolls and parking where they are separate work-related or business travel costs

Private-use costs are not deductible. If a vehicle is used 70% for business and 30% privately, the claim needs to exclude the private portion under the method you use. Do not add the same cost twice, such as claiming cents per kilometre and then separately claiming fuel, registration, insurance, servicing, or depreciation for the same car use.

## Cents per kilometre for self-employed business driving

The [ATO cents per kilometre method](https://www.ato.gov.au/businesses-and-organisations/income-deductions-and-concessions/income-and-deductions-for-business/deductions/deductions-for-motor-vehicle-expenses/cents-per-kilometre-method) applies to sole traders and eligible partnerships claiming car-related business expenses. It uses a set rate for each business kilometre and is capped at 5,000 business kilometres per car, per income year.

For 2024-25 and 2025-26, the rate is 88 cents per kilometre. The rate already takes running costs and depreciation into account, so do not claim those car running costs separately for the same car under this method.

Calculation:

`business kilometres x ATO cents per kilometre rate = deduction`

Example:

| Cents per kilometre figure | Amount |
| --- | ---: |
| Business kilometres for the income year | 3,800 km |
| Rate | $0.88/km |
| Deduction | $3,344 |

You do not need written evidence of exact kilometres in the same way as a logbook, but the ATO may ask how you worked out business kilometres. Keep diary, calendar, route, job, roster, invoice, or app records that explain the number.

## Logbook method for higher business use

The [ATO logbook method](https://www.ato.gov.au/logbook) can be better when you drive more than 5,000 business kilometres, have high running costs, or use the car mostly for business. It lets you claim the business-use percentage of eligible actual car expenses.

The calculation is:

`business kilometres / total kilometres x 100 = business-use percentage`

Then:

`eligible car expenses x business-use percentage = deduction`

Example:

| Logbook figure | Amount |
| --- | ---: |
| Business kilometres in the representative period | 4,200 km |
| Total kilometres in the representative period | 6,000 km |
| Business-use percentage | 70% |
| Eligible annual car expenses | $7,900 |
| Deduction | $5,530 |

Your first logbook normally needs at least 12 continuous representative weeks. Keep odometer readings, journey details, vehicle details, receipts or other expense records, and calculation notes. A logbook can generally be valid for up to five income years if the pattern remains representative, but you still need later-year odometer readings and a new logbook if business use changes.

## Actual costs for non-car vehicles, companies, and trusts

The [ATO actual cost method](https://www.ato.gov.au/businesses-and-organisations/income-deductions-and-concessions/income-and-deductions-for-business/deductions/deductions-for-motor-vehicle-expenses/actual-costs-method) is based on actual receipts and records. It is the required method for companies and trusts, regardless of vehicle type. It is also required for sole traders and partnerships claiming expenses for other vehicles such as motorcycles, some vans, trucks, and vehicles outside the ATO car definition.

Actual costs need stronger year-round evidence because you are claiming actual business-use costs, not a set kilometre rate. Keep records that show:

- receipts and tax invoices for running costs
- loan or lease documents
- registration papers
- kilometres travelled for business and private use
- diary, journal, trip log, or app records showing business purpose
- calculation notes showing how private use was excluded
- depreciation records where decline in value is claimed

If a company or trust vehicle is available for private use by an employee, shareholder, or associate, check FBT and private-company rules before treating the claim as a simple business deduction.

## What counts as business driving?

Business driving is travel that is part of running the business, not just any trip that happens during a workday.

Common examples include:

- travelling between different business premises
- visiting clients or customer sites
- picking up supplies or stock
- delivering goods or documents
- driving to a business meeting, conference, bank, post office, tax agent, or BAS agent
- travelling from a home-based business to another place for business purposes

The [ATO motor vehicle expenses for a home-based business](https://www.ato.gov.au/businesses-and-organisations/income-deductions-and-concessions/income-and-deductions-for-business/deductions/deductions-for-motor-vehicle-expenses/motor-vehicle-expenses-for-a-home-based-business) guidance gives examples such as client visits, equipment or supply purchases, banking, post office trips, and tax or BAS agent visits.

Normal commuting remains a common mistake. For employees, the ATO generally treats home-to-work travel as private except in limited circumstances. For business owners, the question is still whether the trip was for business purposes and whether private use has been excluded.

## If you are self-employed and also an employee

Keep two clean record streams:

- self-employed business trips, matched to business income, invoices, jobs, clients, or business errands
- employee work-related trips, matched to employment duties, allowances, reimbursements, and your income statement

Do not claim the same kilometres twice. Do not treat an employer reimbursement as self-employed business income or expense support without checking the payment. If your employer reimburses an expense and it is not assessable income to you, that same cost generally should not be claimed again as a deduction.

## Mileage tracking records to keep

The [ATO motor vehicle expense records](https://www.ato.gov.au/businesses-and-organisations/income-deductions-and-concessions/income-and-deductions-for-business/deductions/deductions-for-motor-vehicle-expenses/motor-vehicle-expense-records-you-need-to-keep) page says records depend on the method, but business motor vehicle records generally include kilometres for business and private use, receipts, loan or lease documents, tax invoices, registration papers, and details of how the claim was calculated.

For a practical self-employed file, keep:

- trip records by date, vehicle, purpose, and business/private status
- receipts and invoices for fuel, oil, electricity, servicing, repairs, tyres, insurance, and registration
- loan, lease, purchase, and depreciation records
- toll and parking records tied to business trips
- invoices, rosters, job notes, calendar entries, or delivery records that explain why the trip was business-related
- calculation notes showing the selected method and excluded private use
- separate reports for employment and self-employed activity if both apply

Business motor vehicle expense records are generally kept for five years.

## How MyCarTracks helps self-employed drivers

[MyCarTracks automatic mileage tracking](https://www.mycartracks.com/products/automatic-mileage-tracking) can capture trips, help classify business and private driving, and export records by date, vehicle, driver, purpose, and distance. That is useful whether you are comparing cents per kilometre with logbook, preparing records for a tax agent, or separating sole trader kilometres from employment kilometres.

For businesses with multiple vehicles or drivers, [MyCarTracks fleet tracking](https://www.mycartracks.com/products/vehicle-tracking) can help managers review vehicle activity before reimbursement, finance, FBT, or accountant review.

## Common mistakes to avoid

- Using the wrong method for the business structure or vehicle type.
- Treating a ute, van, motorcycle, truck, or minibus as a car without checking the ATO definition.
- Claiming private kilometres or normal commuting as business use without source-supported facts.
- Assuming advertising on the vehicle turns private driving into business driving.
- Treating tools or equipment as enough by itself; bulky-equipment exceptions need the ATO conditions to be met.
- Claiming cents per kilometre and then adding fuel, insurance, registration, servicing, or depreciation separately.
- Reusing a logbook after the business pattern changed.
- Mixing employee and self-employed kilometres in one total with no activity split.
- Keeping receipts but no business/private kilometre support.
- Forgetting that company, trust, employee, shareholder, associate, and FBT treatment can change the answer.

## FAQ

### Can a sole trader claim car expenses in Australia?

Yes, when the vehicle is used for business and the records support the claim. For a car, a sole trader can usually choose cents per kilometre or logbook. For other vehicles, actual costs are used.

### Can a company claim cents per kilometre?

No. A company or trust must use actual costs for motor vehicle expenses. Cents per kilometre is for sole traders and eligible partnerships claiming car-related business expenses.

### How many kilometres can self-employed people claim?

Under cents per kilometre, the cap is 5,000 business kilometres per car, per income year. Under logbook or actual costs, there is no kilometre cap, but the kilometres must be business-related and supported by records.

### What car expenses can I claim with the logbook method?

You can claim the business-use percentage of eligible car expenses such as fuel, oil, electricity, repairs, servicing, registration, insurance, lease payments, eligible finance interest, and decline in value where allowed. Private use must be excluded.

### Can I claim tolls and parking?

Business tolls and parking can be deductible when they relate to business travel and are supported by records. Keep the receipt or account record and connect it to the business trip.

### Do I need a logbook if I use cents per kilometre?

No full 12-week logbook is required for cents per kilometre, but you still need support for the business kilometres. A diary, calendar, route list, job notes, or mileage tracking app can help show how the number was worked out.

### What if I changed from sole trader to company?

Recheck the method from the date the structure changed. Sole traders and companies do not use the same method rules, and company vehicles can raise private-use, shareholder, employee, and FBT issues.
