When your employer offers to help with vehicle costs, you typically face two options: a car allowance or a novated lease. Both put money toward your car, but the tax treatment and real-world savings differ significantly. Understanding car allowance vs novated lease in Australia helps you choose the option that keeps more money in your pocket.
This guide compares the two arrangements side by side, explains the tax implications, and highlights the scenarios where each option wins.
What is a car allowance?
A car allowance is a payment your employer makes — usually a set dollar amount per pay period or per kilometre — to help cover the cost of using your own vehicle for work. Key characteristics:
- Assessable income: The allowance is added to your gross income and taxed at your marginal rate
- You own the car: You purchase, finance, and maintain the vehicle yourself
- You claim deductions: At tax time, you claim your actual work-related car expenses as a deduction against the allowance income
- Flexibility: You choose any car you like, with no restrictions from your employer
The net tax outcome depends on whether your actual car expenses exceed the allowance. If they do, you benefit. If not, the allowance adds to your taxable income.

What is a novated lease?
A novated lease is a salary packaging arrangement where your employer deducts lease payments and running costs from your pre-tax salary. Key characteristics:
- Pre-tax deductions: Lease payments and running costs come out of your salary before income tax is calculated, reducing your taxable income
- Post-tax component: A portion of running costs is deducted post-tax to cover the FBT employee contribution
- FBT applies (usually): Unless the car is an eligible electric vehicle, your employer incurs FBT on the private-use component, which is typically passed through to you as part of the packaging arrangement
- Bundled costs: Insurance, registration, fuel, servicing, and tyres are often bundled into the lease
The financial benefit comes from the combination of pre-tax salary deductions and GST savings on running costs.
Tax treatment compared
Car allowance
- Employer pays allowance (e.g., $15,000/year)
- Allowance is added to your assessable income
- You pay income tax on the allowance at your marginal rate
- At tax time, you claim actual car expenses as a deduction
- Net cost = tax on allowance minus tax benefit of deduction
Novated lease
- Lease payments deducted from pre-tax salary (reducing taxable income)
- Running costs partly pre-tax, partly post-tax
- FBT may apply (employer calculates; often passed to employee via reduced packaging benefit)
- GST credits on car purchase and running costs reduce overall cost
- Net cost = reduced salary minus tax savings minus GST savings
Which saves more?
In most cases, a novated lease produces greater tax savings than a car allowance, particularly when:
- Your marginal tax rate is 32.5% or higher
- The vehicle is a fully electric car (FBT exempt, maximising savings)
- You drive a moderate-to-high number of kilometres annually
- You would be purchasing a new or near-new vehicle anyway
A car allowance may be preferable when:
- You already own your car outright and have low running costs
- Your actual work-related kilometres are very high, producing a large deduction
- You value flexibility and do not want to be locked into a lease term
- Your employer offers a generous per-kilometre rate
Worked example
Scenario: Employee earning $95,000, considering a $45,000 vehicle, driving 15,000 km/year (60% business use).
| Factor | Car Allowance ($12,000/yr) | Novated Lease |
|---|---|---|
| Taxable income impact | +$12,000 income, −expenses deduction | Reduced by pre-tax deductions |
| FBT | None | Applies (unless EV) |
| GST savings | None | ~$4,000 over lease term |
| Flexibility | High | Locked to lease term |
| Admin effort | Self-managed | Employer-managed |
The novated lease typically delivers $2,000–$5,000 more in annual savings for this scenario, with the gap widening significantly for eligible EVs (where FBT is zero).
The EV advantage
The FBT exemption for battery electric vehicles makes novated leasing particularly attractive. With no FBT on eligible EVs, the full pre-tax salary deduction flows through as a saving. Employees on average salaries can save $5,000–$9,000 per year compared to running a conventional car outside of salary packaging.

Record-keeping for both options
Regardless of which arrangement you choose, accurate kilometre records matter:
- Car allowance: You need a trip log or logbook to substantiate your tax deduction. Without records, the ATO may disallow your claim.
- Novated lease (operating cost method): A logbook establishes the business-use percentage, which directly affects the FBT calculation.
Tripbook records every trip automatically, providing the data you need whether you are claiming a deduction against an allowance or supporting your novated lease FBT calculation.
Key takeaway
The car allowance vs novated lease decision depends on your salary, the car you want, your driving patterns, and whether the vehicle qualifies for the EV FBT exemption. In most cases, a novated lease delivers greater tax savings — but a car allowance offers more flexibility and simplicity.
Run the numbers for your specific situation, and whichever option you choose, track your kilometres from day one.
