How should an owner-operator trucker organize fuel receipts and related fuel-tax documentation?

Why does one fuel stop need two kinds of record?

IRS Publication 583 says your supporting documents should show the amount paid and that the amount was for a business expense. IFTA asks more: its Articles of Agreement say every licensee shall maintain records to substantiate information reported on its tax returns, and its Procedures Manual lists what a receipt must contain before pump tax is credited on the return. A card slip proving payment can still fail IFTA for lacking the truck's number or the seller's address.

Distance splits too. Publication 583 says that if you use a vehicle for both business and personal purposes, you must divide your expenses between business and personal use; the records for that belong to a separate question on vehicle and mileage expenses. The IFTA return, as the Procedures Manual sets it out, reports miles traveled within each member jurisdiction, so fuel records alone cannot support it.

The Procedures Manual puts the burden of proof in an IFTA audit on the licensee. If the records produced fail its adequacy criterion for the fleet as a whole, or none are produced after a written demand, the base jurisdiction shall impose an additional assessment.

Does this apply if you never leave one jurisdiction?

The by-jurisdiction records below are IFTA's requirements for its licensees, and IFTA's Articles describe the agreement as making uniform the administration of fuel use taxation for motor vehicles operated in multiple member jurisdictions. If your truck runs only inside one state and is not reported under an IFTA license, the IRS records still apply; ask your state's fuel-tax agency whether it requires any record of its own, and whether you need an IFTA license at all.

The exception is a decaled truck. The Articles let a licensee include a truck operated only within one jurisdiction by obtaining IFTA decals for it, and once decaled it must continue to be reported until the decal expires or the truck is no longer under the licensee's authority.

How do you find your base jurisdiction's rules?

Find them in this order:

1. Identify the base jurisdiction. IFTA's Articles define a licensee as a person holding an uncancelled license issued by the base jurisdiction, and where the carrier assumes reporting under a written lease, they make the carrier's base jurisdiction the base jurisdiction.
2. Read that agency's IFTA manual or guide on record storage, audit location and reefer or auxiliary fuel. The Articles require operational records to be maintained or made available for audit in the base jurisdiction.

What must each fuel receipt show, and how do you check it at the pump?

IFTA's Procedures Manual says that, for tax-paid credit, a valid retail receipt, invoice or transaction listing must contain these elements, which make up the checklist for every stop:

• 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 identification of the qualified motor vehicle the fuel went into
• The purchaser's name, where for a leased truck the lessor's or lessee's name is acceptable if a legal connection can be made between the named purchaser and the licensee

For the IRS, Publication 583 wants the same receipt to show the amount paid and that it was for a business expense, and notes that specific recordkeeping rules apply to travel and transportation expenses (Publication 463); those belong to the separate vehicle-expense question.

IFTA's Articles add that retail fuel earns tax-paid credit only when it is placed into the fuel storage unit of a qualified motor vehicle and its price includes fuel tax paid to a member jurisdiction, and that the receipt must show evidence of tax paid; the Articles leave the specific receipt requirements to Procedures Manual P550, whose content list is the checklist above, and bar any member jurisdiction from requiring evidence beyond what the Procedures Manual specifies. The Procedures Manual refuses credit on a record that has been altered, shows erasures or is illegible unless you can demonstrate it is valid. Its fuel-record rules do not apply to vehicles that travel only where fuel use is taxed purely by distance or their fuel type is untaxed, unless a vehicle of the same fuel type also runs where net taxable fuel is taxed.

At the pump, work in this order:

1. Run the truck's fuel as its own transaction and give the unit number at the pump or card prompt. If the receipt does not show it, get the card provider's transaction listing that does, and if no document you can obtain identifies the truck, ask your base jurisdiction how it wants the vehicle identified.
2. Check the receipt against the list before pulling away, and ask for a complete one while you are still there if anything is missing.
3. Leave the printed receipt untouched, and put the odometer reading and trip number in your own fuel log.
4. Photograph or scan it that day. A faded receipt risks being illegible.

What distance record goes with the fuel?

IFTA's Procedures Manual says a base jurisdiction shall accept as adequate distance records, other than vehicle-tracking data, that substantially document the operation and contain these elements for each trip:

• The beginning and ending dates
• The origin and destination
• The route of travel
• The beginning and ending reading from the odometer, hubodometer, engine control module (ECM) or a similar device
• The total distance
• The distance traveled in each jurisdiction
• The vehicle identification number or unit number

Fill in the trip sheet as the trip runs; a route planner or memory after the quarter closes cannot supply actual odometer readings.

If your miles come from a vehicle-tracking system using latitude and longitude, the Procedures Manual requires a record at least every 10 minutes while the engine is on, each with the date and time, latitude and longitude to at least four decimal places, the ECM odometer reading (or, with no ECM odometer, beginning and ending dashboard odometer or hubodometer readings for the trip) and the vehicle identification or unit number. The data must be accessible in a spreadsheet format such as XLS, XLSX or CSV; a PDF, JPEG, PNG or Word export is not acceptable.

That differs from a deduction mileage log, which separates business from personal use. IFTA's Articles define total distance as all miles traveled in the reporting period by every qualified vehicle in the fleet, taxable or nontaxable, so a personal trip in the truck still goes in the IFTA record.

Can a fuel-card statement or carrier report replace the pump receipt?

For IFTA, it can if it carries every checklist element. The Procedures Manual lets a licensee support tax-paid credit with a receipt, invoice or transaction listing from the seller, a credit-card receipt, a transaction listing generated by a third party, or an electronic or digital record of an original receipt or invoice. A fuel-card report showing date, seller and address, gallons, fuel type, price, truck and purchaser can stand in for paper receipts; a statement or settlement line showing only a date, a merchant and an amount cannot.

For the IRS, Publication 583 says proof of payment of an amount, by itself, does not establish that you are entitled to a deduction, and that you should also keep documents such as credit card sales slips and invoices to show you incurred the cost. Keep the statement as proof of payment and the receipt or detailed listing as proof of the purchase.

Save each period's detailed listing in storage you control. Access to a provider's or carrier's system can end with the relationship, but the Procedures Manual still requires the licensee to make its records available for audit on request.

How do you keep reefer and auxiliary fuel separate?

IFTA's Articles require the licensee to report all fuel placed in the supply storage unit used to propel the qualified motor vehicle, subject to the same distance-tax exemption. One receipt covering the truck and a reefer tank cannot show how much went where, so pump reefer fuel as a separate transaction, note it against the reefer unit in your log, and file it apart from the truck's fuel. Auxiliary equipment that runs off the truck's own tank cannot be pumped separately; California's guide says its Regulation 1432 provides safe-harbor percentages as presumed amounts of diesel used to operate auxiliary equipment, and other jurisdictions may differ, so ask the jurisdiction where you would claim how it wants that fuel supported.

Check your base jurisdiction's IFTA guide for how reefer and auxiliary gallons go on the return. IFTA's Articles send refund claims for tax paid on tax-exempt fuel directly to the respective jurisdiction, so keep the records it asks for. California's guide, for example, says to claim where you paid the tax and used the fuel, under that jurisdiction's own definitions and refund requirements, and that California refunds diesel fuel tax paid on fuel used other than to operate motor vehicles on its public highways, including fuel for auxiliary equipment and for a refrigeration unit with a separate fuel tank or generator. It says those gallons still go in the IFTA schedule's total gallons and miles-per-gallon calculation, except gallons used in refrigeration units with separate tanks, and that you should maintain adequate records to support any refund you claim.

What changes when you are leased to a carrier?

Start with the lease. IFTA's Articles define the lessor as the party granting the use of equipment to another, which is you when you lease your truck on, and for a carrier using independent contractors they provide:

• Trip or short-term leases. On leases of 29 days or less, the trip lessor reports and pays all fuel taxes.
• Long-term leases. On leases of 30 days or more, lessor and lessee may designate which of them reports and pays, and if there is no written agreement, or it is silent, the lessee carrier is responsible.

Household goods carriers follow a separate rule in the Articles. The reporting party holds the IFTA fuel and distance records.

If the carrier reports, your part is the cost side and checking its charges. FMCSA's leasing rule, 49 CFR 376.12, requires the written lease, except where an exemption in that part applies, to specify each party's responsibility for the cost of fuel and fuel taxes, and every item the carrier may pay first and deduct from your compensation at settlement, with how each amount is computed. It says you shall be afforded copies of the documents necessary to determine the validity of each charge. From each settlement, request and keep:

• The settlement statement
• The fuel-card transaction detail behind each fuel charge-back
• The documents behind each fuel-tax charge-back or credit
• The record of each fuel advance and the settlement that recovered it
• A copy of the lease

Check each fuel charge-back against your own pump receipts and fuel log, not only the carrier's report. Where a settlement recovers an advance you spent on fuel, the pump receipt is the fuel record and the expense, and the settlement line only repays the advance. On the carrier's card, the settlement charge-back is the payment for the fuel on your pump receipt, so post the fuel expense once, from the receipt or from the settlement line, never both. Book a fuel-tax charge-back or credit to the Fuel expense: IFTA net sub-account used below, not as another fuel purchase, because the pump tax is already inside fuel expense.

If you report under your own IFTA license, these become your fuel records. A carrier-card receipt may name the carrier, which the purchaser element allows if a legal connection can be made; the Articles say no member jurisdiction shall require leases to be filed but they shall be made available upon request, so keep the lease with the fuel records. Where the carrier's report lacks a checklist element, keep your own pump receipt and ask the carrier in writing for the missing detail the day you find the gap.

How do you keep personal and non-fleet fuel out?

Fuel for your car or any vehicle outside the reporting fleet stays out of the IFTA figures: the Procedures Manual says the base jurisdiction shall not allow tax-paid credit for fuel placed into a vehicle other than a qualified motor vehicle. Personal fuel also stays out of fuel expense, since Publication 583 wants documents showing a business expense; a sole proprietor posts it to owner's draw, and if your business is a corporation, ask your bookkeeper which account it uses. Under IFTA's Articles, fuel put into the truck on a personal trip still goes in the IFTA fuel figures, as its miles go in the distance record; only its IRS expense is split, under the separate vehicle-expense question. Business fuel for a vehicle outside the IFTA fleet, such as a service pickup, stays in expenses but out of IFTA. Keep the truck's card for the truck, and mark any stray purchase the day you see it.

How do you record fuel cost and fuel tax without counting either twice?

IRS Publication 334 says taxes on diesel and other motor fuels you use in your business are usually included as part of the cost of the fuel, and says not to deduct these taxes as a separate item. Post the pump price, tax included, to fuel expense once, and do not split the tax out again. Publication 334 adds that you may be entitled to a credit or refund of federal excise tax paid on fuels used for certain purposes (see Publication 510); if you claim one, record it once and ask your preparer which account it belongs in.

The IFTA return then settles tax owed on miles in each jurisdiction against tax paid at the pump: the Procedures Manual has it report tax-paid fuel purchased within each member jurisdiction, and the Articles give a licensee full credit or refund for tax-paid fuel used outside the jurisdiction where it was bought. Book only the net result, because the pump tax is already in fuel expense; interest or penalty goes to its own account.

Publication 334 says that under an accrual method you generally deduct or capitalize expenses in the year incurred, and under the cash method in the tax year you actually pay them:

• Accrual basis. Because FASB's Concepts Statement No. 8, Chapter 4, counts taxes imposed by governments among obligations and requires a liability's obligation, even one settled later, or an asset's right to exist at the financial statement date, record the quarter's net tax due as a payable, or a net credit as a receivable, dated at the end of the quarter the fuel and miles belong to, using the figures the return computes. Publication 334 conditions an accrual-method deduction on the all-events test and economic performance, so confirm with your tax preparer the year in which a quarter's IFTA net is deducted.
• Cash basis. Record net tax when you pay it and a refund when you receive it. A credit used against a later return shows up only as that return's smaller payment.

In this accrual-basis example with invented figures, a quarter's fuel costs 9,600.00 paid in cash, its return shows 180.00 net due, and the next quarter's return shows a 75.00 net credit:

On the cash basis, drop the second and fourth entries: the payment posts 180.00 to Fuel expense: IFTA net against cash, and the 75.00 posts when refunded or as a smaller later payment. On the accrual basis, a credit used on a later return clears the receivable against that return's payable. Either way each amount reaches the books once.

What should you check before a quarter's records are final?

If you report, run every check below before the return is prepared; if the carrier reports, run the first and last against your settlements:

• Every fuel purchase on card statements, settlements and cash records matches a receipt or listing carrying every checklist element.
• Every trip has a distance record, each trip's ending odometer reading meets the next trip's starting reading, and each trip's miles by jurisdiction add up to its total.
• Fuel and distance records start and end on the same dates.
• Reefer fuel (under your base jurisdiction's reefer rule) and fuel for your car or any other vehicle outside the IFTA fleet are out of the IFTA fuel figures; every gallon put into the truck stays in, personal trip or not.
• A monthly summary shows each truck's miles and fuel, in total and by jurisdiction, which the Procedures Manual says may be necessary for an efficient audit.
• The quarter's miles per gallon is close to your usual figure, and a sharp change sends you looking for a missing receipt or trip.
• Each fuel and fuel-tax charge-back matches your own receipts and the carrier's supporting documents.

Start fixing a gap the day the check finds it, alongside the remaining checks, so no request is still waiting when the return falls due:

How long, and in what form, do you keep the records?

IFTA's Procedures Manual says a licensee shall retain its records for four years following the date the IFTA return was due or was filed, whichever is later, plus any period covered by waivers or jeopardy assessments, and must preserve fuel and distance records for any periods under audit in accordance with the base jurisdiction's laws. A refund request extends the period for records on that refund until the request is granted or denied. IRS Publication 583 runs a separate clock: keep records that support an item of income or deduction on a return until the period of limitations for that return runs out. Publication 583's Table 3 lists those periods for income tax returns; unless the table says otherwise, they run from when the return was filed, and a return filed early counts as filed on its due date. Keep each record until the later of the two ends.

On form, the Procedures Manual lets adequate records be produced through any means and kept in any format or medium available to the licensee and accessible by the base jurisdiction; records it cannot audit have not been made available. The Articles allow microfilm, microfiche or other computerized or condensed record storage meeting the base jurisdiction's legal requirement, and Publication 583 applies all hard-copy requirements to electronic storage systems. Dated scans filed by quarter and truck, with trip sheets and settlements beside them, in storage you control with a backup, serve both only if they meet your base jurisdiction's legal requirement for stored records and Publication 583's conditions for electronic records: indexed, preserved and reproducible in legible form, complete and accurate, and accessible to the IRS. Keep tracking-system data in its spreadsheet export rather than as scans. Publication 583 lets paper originals be destroyed only once the storage system has been tested to show it reproduces them in compliance with IRS requirements and procedures are in place to keep it compliant, so keep them until then.
