Keeping Records

All motor carriers operating in Oregon must maintain records of their motor vehicle operations for a period of three years and must produce these records for inspection upon request. If operating under the International Registration Plan and International Fuel Tax Agreement, carriers must maintain all records pertaining to such operations as required by IRP and IFTA.

Why keep records?

A motor carrier should view good recordkeeping as a way to save time and money. Maintaining good records allows auditors to verify the accuracy of operations including taxes and fees paid by a motor carrier. Without adequate records, additional fees and penalties may be assessed.

How to Keep Tax Records

The Commerce and Compliance Division has a motor carrier’s guide to recordkeeping with detailed information about:
  • How do I record all that information?
  • What information must be kept?
  • How long do I keep records?
  • Who's going to look at those records?

(1) All carriers must maintain records of their motor vehicle operations and make reports on forms approved by the Department. Such records must be:
  • Stored at the carrier’s principal office or place of business.
  • Made available for inspection by the Department or its representatives upon request; and
  • Retained for a period of three (3) years unless otherwise authorized by the Department.
(2) Distance records produced by a means other than a vehicle-tracking system must meet all requirements in section (1) of this rule and contain the following information for each vehicle:
  • Origin and destination points.
  • Oregon entry and exit points.
  • Actual Oregon miles for each trip.
  • Pickup and delivery points in Oregon for each trip;
  • Routes of travel for each trip.
  • Dates of each trip.
  • Daily beginning and ending odometer or other mileage recording device readings for each vehicle.
(3) Distance records produced wholly or partly by a vehicle-tracking system, including a system based on a global positioning system (GPS) may be used in lieu of, or in addition to, the records required in this rule provided the electronic records meet all the requirements of section (1) of this rule and contain the following information for each vehicle:
  • The original latitude and longitude coordinates carried out to, at minimum, 5 decimal places, for the vehicle to which the records pertain.
  • The date and time of each coordinate capture, at a minimum of 15-minute intervals and at every significant event to validate the total distance traveled. A significant event is defined as: Engine being turned on or off and crossing into or out of the State of Oregon.
  • The daily beginning and ending reading from the odometer, hubodometer, engine control module (ECM), or any similar device.
  • The calculated distance between each GPS or other system reading.
  • The total distance traveled by the vehicle in Oregon; and
  • Exception reports containing adjustments made to distance traveled in Oregon including equipment malfunction, tampering or random unexplained coordinate capture.
(4) In addition to the requirements listed above, all carriers must maintain records containing the following information for each vehicle:
  • Identification of any exempt miles claimed, which shall include beginning and ending odometer or other mileage recording device readings for the exempt portion of each trip. If repeated trips are made to and from the same locations, a one-time recording of odometer or other mileage recording device readings for the exempt portion of those trips may be applied to the total number of trips.
  • Load tickets and/or bills of lading for each shipment transported.
  • A monthly summary of the total distance traveled in Oregon and the total taxable distance traveled in Oregon in each configuration;.
  • Carriers operating motor vehicles that are issued or required to obtain an annual variance permit under ORS 818.200(1)(a) to (c) with a combined weight of more than 80,000 pounds shall also provide for each reporting period:
    • Number of axles in the vehicle configuration; and
    • A record of changes of operation. A change of operation occurs when the vehicle configuration remains the same but the actual weight of the vehicle and load changes from over 80,000 pounds to 80,000 pounds or under. Empty movements are not changes in operation; and
  • Carriers operating motor vehicles in multiple configurations shall provide the number of miles operated in each motor vehicle configuration for each trip.

(5) All registrants that pay registration fees via registration trip permits must retain a copy of each registration trip permit.

Motor carriers can buy fuel in Oregon at commercial fueling stations without paying a fuel tax if they enroll in the Oregon Weight-Mile Tax Program. Without proper enrollment, the fuel provider must charge fuel taxes.

When a carrier who is paying weight-mile taxes also pays a fuel tax, they can request a refund of the fuel tax on their next weight-mile tax report with the ODOT Commerce and Compliance Division. A claim for credit can be processed when it is supported by proper documentation from the actual seller of the fuel. See OAR 740-055-0110 for information required on fuel purchase records and refunds.

The seller of fuel must provide a copy of the invoice for every sale to the user upon request as required by ORS 319.671 and OAR Chapter 735 Division 176. The invoice shall show all information required by ODOT for the verification of fuel tax credits. If it is necessary to generate a handwritten receipt or invoice, it still must contain all required information.

Note: Handwritten receipts may not be submitted for B20 Biodiesel fuel since this fuel is exempt from taxation in accordance with ORS 319.530​.

​The following IRP and IFTA records must be maintained for a period of four years and made available upon request.

Both IRP and IFTA distance recordkeeping require the carrier to record all operations with the following information:
  • Origin and destination points of each trip.
  • Routes of travel for each trip.
  • The beginning and ending dates of the trip.
  • The beginning and ending reading from the odometer, hubodometer, engine control module (ECM), or any similar device for the trip.
  • Total distance of the trip.
  • The distance traveled in each jurisdiction during the trip.
  • Unit number or vehicle identification number.
  • Monthly distance summaries for each vehicle and each jurisdiction.
  • Quarterly distance summaries for the vehicles and for each jurisdiction.
  • IRP requires an annual summary of the quarterly summaries.
Distance records produced by a vehicle tracking system (GPS) that utilizes latitudes and longitudes, must be created at a minimum of:
  • For IRP, every 15 minutes when the vehicle’s engine is on.
  • For IFTA, every 10 minutes when the vehicle’s engine is on and must also include the following data elements:
    • The date and time of each system reading.
    • The latitude and longitude to include a minimum of 4 decimal places (0.0001) of each system reading.
    • Monthly summary of miles.
    • The odometer reading from the engine control module (ECM) of each system reading.  If no ECM odometer is available, a beginning and ending dashboard odometer or hubometer for the trip will be acceptable.
    • Vehicle identification number or vehicle unit number.
This data must be accessible in an electronic spreadsheet format such as XLS, XLSX, SCV, or delimited text file.

IFTA recordkeeping also requires additional fuel records.
  • The carrier must maintain complete records of all motor fuel purchased, received or used in its business.
  • The fuels records must be adequate to verify the total amount of fuel placed into the qualified vehicles.
  • Complete fuel records must be maintained for each fuel type.
  • The carrier must maintain monthly summaries of all fuel placed into each vehicle during the quarter.
  • Receipts that have been altered or indicate erasures are not accepted for tax-paid credits unless the licensee can demonstrate that the receipt is valid.
  • ORS 319.671 and OAR Chapter 735 Division 176 requires the seller of fuel to provide a copy of the invoice for every sale to the user upon request.
A valid receipt, invoice or transaction listing for tax-paid fuel credit must contain the following:
  • Purchaser’s name.
  • Seller’s name and address.
  • Date of purchase.
  • Fuel type.
  • Price per gallon.
  • Unit number.
  • Number of gallons received.
Bulk Fuel Records (if applicable) must contain the following elements for each bulk fuel withdrawal:
  • Date of withdrawal.
  • Number of gallons withdrawn.
  • Fuel type.
  • Unit number.
  • Purchase and inventory records to confirm that tax was paid and must distinguish fuel placed in qualified vehicles from other uses.
  • Receipts for all deliveries.
  • Quarterly inventory reconciliations for each tank.
  • Capacity of each tank.
  • Bulk withdrawal records for every bulk tank at each location.
  • Location of bulk tank(s) from which withdrawal was made.
Failure to maintain the above records may result in disallowance of tax-paid credits claimed on the IFTA tax returns in addition to assessing a 20 percent reduction in reported miles per gallon (MPG) or assessing a fleet MPG of 4.0.

​Carriers can save time and trouble when trucks are stopped at roadside and weigh stations for inspection by having the following documents ready to show an inspector.

  • Driver’s license.
  • Medical examiner’s certificate.
  • Medical waiver (Skills Performance Evaluation), if applicable.
  • Record of duty status (logbook).
  • Trip receipts.
  • Shipping/delivery papers or manifest.
