Nebraska Form 84AG Guide: How Farmers Get a Fuel Tax Refund (2026)

Introduction: This guide explains how Nebraska farmers and ranchers can claim a refund for state motor fuels tax paid on gasoline and diesel used in unlicensed agricultural equipment. Using Form 84AG, you can recover a portion of the tax paid for fuel used in tractors, combines, irrigation pumps, and other off-road farm machinery. The key takeaway is that meticulous record-keeping and understanding the specific farm documentation required are essential for a successful claim.


1. Eligibility & Deadline Decoder: The Farmer’s Checklist

Who Qualifies: Any farmer, rancher, or agricultural producer who paid Nebraska motor fuel tax on fuel used exclusively in unlicensed equipment for farming or ranching purposes.

⚠️ Critical Rule: Fuel used in any licensed motor vehicle (e.g., pickup trucks, semi-trucks for hauling on public roads) is NOT eligible for a refund, with no exceptions. This is the most common reason for claim denial.

Contact & SubmissionMail only. No online filing. Address: NE Dept. of Revenue, PO Box 98904, Lincoln, NE 68509-8904. Phone: 800-554-3835All communication and submission is paper-based.

Documentation Required (The Audit Trail):

  • Farm Description: Acreage, crop types, livestock counts (annually).
  • Equipment List: Make, model, HP, and fuel type for each piece of unlicensed equipment (annually).
  • Fuel Storage Information: Details on bulk tanks and controls to prevent misuse.
  • Invoices: Legible copies of all fuel purchase receipts.
  • Withdrawal Logs: Mandatory if you fuel both licensed trucks and unlicensed equipment from the same bulk tank.

2. Step-by-Step Claim Process for Form 84AG

Step 1: Gather the Foundational Farm Documents
Before looking at a single invoice, prepare these required attachments:

  1. Description of Operations: Write a brief summary including total acres farmed, types of crops, and number/type of livestock.
  2. Detailed Equipment List: Create a table listing each piece of unlicensed equipment (e.g., John Deere 8300 Tractor, Caterpillar 299D Skid Steer). Include make, model, horsepower, and whether it uses gas or diesel.
  3. Map Your Fuel Flow: Answer the storage questions on the form. If you have a bulk tank, note its size/location and describe the physical or procedural controls (e.g., separate pumps, locked fittings) that ensure fuel is only used for farm equipment.
    Pitfall: Submitting a claim without these annual documentation sheets will result in a delay or a request for more information.

Step 2: Collect & Annotate Fuel Invoices
Gather all fuel purchase receipts for the claim period. Each invoice must show:

  • Seller name/address
  • Date of purchase
  • Fuel type (Gasoline/Undyed Diesel)
  • Gallons purchased
  • Amount of tax paid
    Pro Tip: If you pumped fuel directly from a station into a piece of equipment (e.g., filling a tractor at the co-op), write the equipment name/ID on that invoice. This creates a direct audit trail.

Step 3: Maintain Withdrawal Logs (If Applicable)
IF you have a bulk tank that fuels both farm equipment (unlicensed) and pickup trucks (licensed), you MUST keep daily withdrawal logs. Each log entry needs:

  • Date
  • Gallons withdrawn
  • Specific piece of equipment fueled
  • Purpose of the use
    Pitfall: This is the #1 audit trigger. Without logs, the DOR may disallow the entire claim from the bulk tank, assuming the fuel went into licensed vehicles.

Step 4: Calculate Your Refund & Complete Form 84AG

  1. Sort invoices by fuel type and purchase date.
  2. Use the Official Rate Table: Find the correct cents-per-gallon refund rate for each purchase date (rates change every 6 months; see the Nebraska DOR website).
  3. Calculate: (Gallons) x (Refund Rate) = Refund Amount.
  4. Apply Rounding: Round amounts .50 to .99 up; round amounts below .50 down.
  5. Transfer totals to the form. Attach a calculation summary if using multiple rates.
  6. Sign the declaration under penalties of perjury.

Step 5: Submit & Retain Your Package

  • Mail the completed Form 84AG, farm description, equipment list, invoices, and logs (if needed) to the PO Box.
  • Send COPIES only. The DOR does not return documentation.
  • Keep a full, identical copy for your records. Claims are subject to audit for 3 years.

Processing & Payment: Expect 6-10 weeks for processing. Refunds are issued via check mailed to your farm address.

4. Pro Tips & Common Rejection Reasons

Maximize Your Refund & Avoid Delays:

  • Batch for the Minimum: If your annual fuel tax is close to $25 per fuel type, file one annual claim instead of quarterly to ensure you meet the minimum.
  • Log Everything from Bulk Tanks: Treat withdrawal logs as non-negotiable. Use a notepad in the shop or a digital app to record every gallon.
  • Annotate Invoices On-Site: Carry a pen and immediately write the equipment ID (e.g., “JD 8400”) on the receipt when you fill up directly.
  • Create a Master File: Keep a permanent folder with your current Farm Description and Equipment List. Update it annually and simply attach a copy to each claim.

Most Common Reasons for Denial:

  1. Highway Use: Claiming fuel used in licensed pickup trucks or semi-trucks.
  2. Missing Withdrawal Logs: For farms with shared bulk storage, lacking logs leads to a full denial of fuel from that tank.
  3. Insufficient Farm Documentation: No Description of Operations or Equipment List attached.
  4. Claim Under $25: The total tax refund requested for gasoline (or diesel) in a calendar year is below the minimum.
  5. Illegible or Incomplete Invoices: Copies where date, gallons, or seller information is missing or blurred.

Appeal Procedure:
A denial notice is the DOR’s final determination. You have a strict 30-day deadline from the date on the notice to file a formal appeal with the District Court of Lancaster County. Given the legal complexity, consulting a tax attorney familiar with Nebraska revenue law is highly recommended at this stage.

  • No Highway Vehicles, Ever. Fuel for pickup trucks is never refundable. This rule is absolute.
  • Documentation is Your Best Defense. Your Farm Description, Equipment List, and Withdrawal Logs are just as important as your invoices.
  • Bulk Tanks Require Logs. If you share a tank between equipment and trucks, daily logs are mandatory.
  • Audits Last 3 Years. Keep every receipt, log, and form copy for three years after filing.
