How do fuel cards work? From the pump to your IFTA return

A fuel card works in three stages: the driver identifies the purchase at the pump, the provider authorizes it against your rules, and the transaction posts to your account with line-item detail. You then pay the provider on the card's terms.

• At the pump. The driver inserts, swipes, or taps the card and answers the prompts your account requires, commonly a PIN or driver ID, a unit number, and an odometer reading.
• Authorization. Before the pump turns on, the provider checks the sale against your controls, such as product type, gallon or dollar limits, time of day, and location. A sale outside the rules is declined.
• Posting. The purchase lands in your account with the station, date, gallons, fuel type, price, card, and the prompt answers attached.
• Billing. You pay the provider through a credit line billed on a cycle, a line backed by a deposit, or a prepaid balance you fund in advance.

The prompts are what make the data useful. An odometer reading at every fill-up gives you miles per gallon by truck, and a unit number ties the gallons to a vehicle, which your IFTA records need.

How is a fuel card different from a business credit card?

A business credit card approves almost any purchase up to its limit, and its statement shows little more than the amount, the merchant, and the date. A fuel card limits what can be bought and records fuel-level detail: gallons, fuel type, and the truck.

For a fleet, that detail is the point. It is what lets you track fuel cost per truck and file fuel tax without a shoebox of paper receipts.

To get a fuel card, decide what it must control, compare providers on net price, apply with your business details, and set the controls before the cards reach drivers.

Step 1: Decide what the card must control

List your trucks, drivers, lanes, and the products you will allow, such as diesel, DEF, and reefer fuel. Decide whether each card belongs to a truck or to a driver. Driver cards need a mandatory unit-number prompt, or your records cannot tie gallons to a vehicle.

Step 2: Compare the net price, not the discount

Ask every provider the same questions:

• How is the discount calculated: a fixed amount off the pump price, a price based on the station's cost, or a rebate paid later?
• At which stations does the discount apply, and what happens outside the network?
• Which fees apply: per card, per transaction, out-of-network, reporting, late payment?
• What are the billing cycle and payment terms?

Then price a typical month of your own fuel stops under each offer. A deep discount at stations your drivers never pass is worth nothing.

Step 3: Apply with your business details

Providers ask for your business information and usually review credit before offering a credit line. If your authority is new and your business credit is thin, ask for a card backed by a security deposit or a prepaid balance instead.

Step 4: Set the controls before cards ship

Assign a PIN to each driver, turn on the prompts, restrict products, and set per-transaction and daily limits that fit your tank sizes and routes. Turn on alerts for declined or unusual sales.

Step 5: Review transactions every week

Match fuel to miles. Flag fills larger than the tank, purchases off the route, two fills close together, and gallons with no matching trip. A weekly review is how a card's controls turn into savings.

IFTA accepts a fuel card transaction listing as proof of tax-paid fuel when each purchase shows the details the IFTA Procedures Manual requires. Section P550 allows a seller's receipt or invoice, a credit-card receipt, a transaction listing generated by a third party, or an electronic record of an original receipt. Each one must show:

• The date of the purchase
• The seller's name and address, or a properly identified vendor code
• The quantity of fuel
• The type of fuel
• The price per volume or the total price
• The qualified motor vehicle the fuel went into
• The purchaser's name; for a leased vehicle, the lessor or lessee, if they can be legally connected to the licensee

Vehicle identification is the usual gap. Fuel put into a vehicle that is not a qualified motor vehicle earns no tax-paid credit, and the records must be kept four years after the return was due or filed, whichever is later. Our IFTA quarterly return guide covers the distance records that go with them.

For income tax, a card statement proves you paid, not what you bought. IRS Publication 583 says a credit card statement shows the amount, payee, and transaction date, and that proof of payment alone does not establish a deduction, so keep the sales slips or invoices too. Our list of trucker tax deductions covers fuel and the rest.

Leased to a carrier? Fuel is a chargeback

If you are an owner-operator leased to a carrier and you fuel on the carrier's card, the carrier pays the station and deducts the cost from your settlement. Under 49 CFR 376.12(h), the lease must list every charge-back item and how each is computed, and you are entitled to copies of the documents needed to check the charge.

The lease must also state that you are not required to buy or rent products, equipment, or services from the carrier as a condition of the lease. Compare the carrier's fuel price with what your own card would cost before you decide.
