If you're spending $200+ per week on diesel or petrol for your work ute, van, or fleet — and you're either paying cash or using a personal card — you're making your life unnecessarily complicated and potentially leaving tax deductions on the table.

A business fuel card is one of the simplest financial tools a tradie can implement. It centralises fuel purchases, provides itemised statements that satisfy ATO requirements, often comes with discounts at major service stations, and separates fuel costs from personal spending automatically.

This guide covers how fuel cards work, which ones are worth using, what they cost, and how to use them correctly for maximum tax benefit.

What Is a Business Fuel Card?

A business fuel card is a payment card — similar to a credit or charge card — that's used exclusively for purchasing fuel and sometimes other vehicle costs (tyres, oil, servicing) at participating service stations.

Unlike a personal credit card, a fuel card:

  • Is issued to your business (ABN-linked)
  • Provides detailed transaction reports showing date, location, litres, and price per litre
  • Often integrates with accounting software
  • May be assigned to specific vehicles or drivers for fleet management
  • Provides a consolidated statement for BAS and tax purposes

The Tax Deduction Benefit

Fuel is a legitimate business deduction for any vehicle used for work purposes. Whether you claim using the cents-per-kilometre method (88c/km for 2025–26) or the actual expenses method, fuel costs have a place in your deductions.

Under the actual expenses method:

  • Your fuel purchases are directly deductible at the percentage of business use
  • A fuel card provides clear, date-stamped evidence of every purchase
  • The ATO accepts digital records, so your fuel card statements satisfy record-keeping requirements
  • Fuel purchase totals from your card can feed directly into Xero or MYOB, reducing admin time

Under the cents-per-kilometre method:

  • The 88c/km rate is designed to cover all running costs including fuel
  • You don't separately claim fuel costs under this method — they're included in the per-km rate
  • Fuel cards still provide value for accurate recording of business driving patterns

Practical recommendation: For most tradies using one work vehicle with mixed personal/business use, the logbook + actual expenses method often yields a higher deduction than cents-per-km. A fuel card supports this method by providing clear records.

How Business Fuel Cards Work

How You Get Fuel

You use the card at any participating service station. Depending on the card, you may need to enter a PIN, odometer reading, or driver ID at the pump. Some modern cards work via app.

Payment Structure

Most fuel cards work on one of two models:

  1. Charge card / pay later: You rack up a balance and pay the entire amount weekly or monthly. No pre-loaded balance required. The card company invoices you with a consolidated statement.
  2. Prepaid: You load funds onto the card and draw down as fuel is purchased. Better cash flow control, but requires active top-up management.

Tax Invoice Requirements

For deductions over $82.50 (including GST), the ATO requires a valid tax invoice. Fuel card statements typically serve this purpose because they include:

  • Supplier ABN
  • Date of purchase
  • Description (fuel type)
  • GST amount
  • Total amount

Your monthly fuel card statement may satisfy tax invoice requirements for all transactions in aggregate. Verify with your accountant that your specific card's statements meet ATO requirements.

The Major Fuel Cards Available to Australian Tradies

1. Motorpass (Ampol)

Best for: Tradies using Ampol/Caltex/United stations
Network: 4,500+ service stations across Australia
Discount: Cents-per-litre discount at Ampol and participating stations
Reporting: Detailed online portal with vehicle and driver reports
Accounting integration: Yes — integrates with major software

Motorpass is one of Australia's largest fuel card networks and is a strong all-round choice, particularly in regional areas where the Ampol/Caltex network is strong.

2. Shell Card (Viva Energy)

Best for: Tradies in urban/suburban areas with heavy Shell station use
Network: 1,800+ Shell and Coles Express stations
Discount: Volume-based discounts available
Reporting: Online portal, downloadable statements
Accounting integration: CSV exports compatible with major software
Cost: Standard card available, fleet accounts attract better terms

Shell Card is a solid option if you're near Shell or Coles Express stations. Less useful in regional areas where Shell's network is thinner.

3. BP Plus

Best for: BP-heavy users, businesses needing vehicle servicing coverage
Network: BP stations nationally + some vehicle service facilities
Discount: Per-litre rebates based on volume
Reporting: Detailed statements with cost centre allocation
Accounting integration: Integrates with Xero, MYOB
Cost: Annual fee applies, waived at higher spend
Key feature: Can also cover tyres and servicing at participating BP Auto centres

BP Plus is particularly useful for tradies who service their vehicles at BP Auto centres — you can put fuel AND servicing on one card, simplifying expense tracking.

4. Puma Energy Card

Best for: Regional and rural tradies, fleet operators
Network: Strong in regional Australia
Discount: Fixed-price diesel at some locations
Reporting: Statement reporting
Cost: Competitive fees

Puma is an underutilised option with strong coverage in regional areas where the major brands have limited presence.

5. Multi-Network / Universal Cards (e.g., Fuelman, Fleetcard)

Some cards work across multiple service station brands, offering maximum flexibility. These are particularly useful for businesses with vehicles travelling across different regions.

What Fuel Cards Cost

Fuel cards are generally low-cost products:

  • Card issuance fee: $0–$30 per card
  • Annual fee: $0–$150 per card depending on card tier and spend level
  • Transaction fees: Usually nil
  • Late payment fees: Apply if you don't pay the balance by due date

Many cards waive fees once monthly spend exceeds a certain threshold ($200–$500/month).

The discount benefit usually outweighs the fee cost. Even a 2c/litre discount on 200 litres per week = $4/week = $208/year — which covers most annual card fees.

Fuel Card Discounts: What to Expect

Discount structures vary by card and spend level:

  • Motorpass — Fixed cents-per-litre rebate — 2–6c/litre
  • Shell Card — Volume-based rebate — 2–5c/litre
  • BP Plus — Per-litre rebate — 2–4c/litre
  • Fleet-specific cards — Negotiated rate — 5–10c/litre+

At 250 litres per week (a typical fleet vehicle), a 4c/litre saving = $10/week = $520/year per vehicle. For a tradie running 2–3 work vehicles, the savings become meaningful.

Some cards also offer discounts on vehicle expenses beyond fuel — oil, tyres, servicing — further consolidating business vehicle expenses in one statement.

How to Use Your Fuel Card for Maximum Tax Benefit

Step 1: Get a Separate Card per Vehicle

If you have multiple vehicles, get a separate card assigned to each. This lets you see fuel cost per vehicle without manual splitting — useful for job costing and understanding which vehicles are the most economical.

Step 2: Set Up Odometer Recording

Most fuel cards allow (and some require) odometer entry at each fill. This builds a detailed record of kilometres travelled per fuel-up — invaluable for:

  • Calculating your actual kilometres per litre
  • Supporting vehicle logbook data
  • Providing additional evidence to the ATO of business use

Step 3: Connect to Your Accounting Software

Most major fuel cards export data in CSV or integrate directly with Xero and MYOB. Set this up from day one. Monthly fuel expenses then flow directly into your accounts without manual entry.

Step 4: Store Statements Digitally

Download your monthly statement as a PDF. Store it in a cloud folder (Google Drive, Dropbox) organised by year. You need to keep these records for 5 years from the tax return lodgement date.

Step 5: Reconcile Monthly

When you reconcile your business accounts, check fuel card charges against your bank account debit (if post-pay) or your prepaid balance top-ups. Catch any personal fuel purchases that accidentally went on the card and exclude those from your deduction.

Fuel Cards and the Logbook Method

If you're using the logbook method for vehicle deductions (actual expenses), your fuel card supports the claim in several ways:

  1. Evidence of fuel cost: Monthly statements show total fuel spend — one component of actual expenses
  2. Location data: Many cards record the service station address, which helps confirm work-related driving patterns
  3. Timing data: Transaction timestamps can be cross-referenced with job records from Tradify or similar software to demonstrate business use

The logbook method typically requires:

  • A 12-week logbook recording every business trip (date, destination, reason, km)
  • Records of actual vehicle running costs (fuel, insurance, registration, servicing, loan interest)

Fuel card records make the "fuel costs" component straightforward to calculate and substantiate.

Fuel Tax Credits — An Additional Benefit Many Tradies Miss

If you're using fuel in non-road activities — operating machinery, plant, or equipment off-road — you may be entitled to the Fuel Tax Credit (FTC).

This is separate from your fuel deduction and is claimed on your BAS. It applies to fuel used in:

  • Light vehicles operating off public roads (construction sites, mining, agriculture)
  • Heavy vehicles (over 4.5 tonne) used on public roads
  • Machinery and equipment (generators, compressors, pumps)
  • Rail transport

The FTC rate varies by fuel type and use. For diesel used in machinery by a business in the 2025–26 year, the rate is approximately 49.6 cents per litre.

Fuel cards help you calculate FTC claims because they show exactly how many litres were purchased and when. If some of that fuel went into a generator or site equipment, you can calculate the proportion eligible for FTC.

For tradies with significant off-road fuel use or equipment operation, FTC can add up to thousands of dollars per year in additional cash refunds from the ATO.

Fleet Management Benefits (For Tradies With Multiple Vehicles)

If you run 3+ vehicles, fuel cards become a fleet management tool, not just a payment method:

  • Cost per vehicle: See exactly what each vehicle costs in fuel monthly
  • Driver allocation: Assign cards to specific drivers and track individual spending
  • Odometer tracking: Compare km per litre across vehicles to identify maintenance issues (a sudden drop in fuel efficiency signals a mechanical problem)
  • Spending alerts: Set limits per card or trigger alerts if unusual spending occurs — useful for detecting misuse

For tradies scaling from 1 vehicle to a small fleet, this management information justifies the card even if the discount benefit is modest.

Frequently Asked Questions

Q: Can I use a fuel card if I use the cents-per-km method?
Yes, though the separate fuel deduction isn't available under this method. The fuel card still simplifies record-keeping and the discount benefit remains. The card can also support accurate odometer tracking, which is useful if you ever switch to the actual expenses method.

Q: Can employees use the business fuel card?
Yes. Most cards can be issued to multiple employees or assigned to vehicles. Set up separate cards per driver for clear expense tracking. For FBT purposes, ensure any private fuel use is tracked and accounted for — employees filling up personal cars on the business card creates an FBT issue.

Q: My card statement shows fuel at personal trips I took over the weekend — what do I do?
Don't claim those transactions in your business deduction. When reconciling your fuel card statement, manually identify any personal use and exclude it from your business expense total. Your accountant can help with this if the volume is significant.

Q: Do fuel cards affect my BAS?
Yes — fuel purchases include GST (10%). If you're registered for GST, you claim the GST on fuel purchases as an input tax credit on your BAS. Your fuel card statement provides the evidence for this claim. The GST-inclusive total divided by 11 equals the GST component to claim.
