Frequently Asked Questions

Fuel Refund Institute helps U.S. businesses recover money paid in federal and state fuel taxes for fuel used in non-taxable operations — such as auxiliary equipment (cranes, reefers, cement pumpers, garbage trucks, etc.). We manage the entire refund process, from analysis to filing and refund tracking.

Any business that uses undyed fuel-powered equipment where the fuel powers something other than the vehicle's movement on public highways may qualify. Examples include crane hydraulics, reefer unit refrigeration, cement pumper operations, garbage compactor systems, and auxiliary engines or PTO (Power Take-Off) systems. If your fleet includes these types of vehicles, you likely qualify.

Refund amounts vary by state, operation type, and fuel usage — but it's often hundreds to thousands of dollars per vehicle per year. FRI clients typically recover $1,000–$50,000+ annually in diesel tax refunds depending on fleet size and auxiliary usage. On average, businesses that qualify lose about $100 each day that passes without filing their refund.

We typically need fuel purchase invoices or fuel card statements, equipment lists (with PTO or auxiliary systems), mileage or usage summaries, and business details including tax identification. Our team helps you gather and format everything correctly for submission.

Once submitted, most claims are processed by the California Department of Tax and Fee Administration (CDTFA) or your relevant state agency within 8–12 weeks, depending on the complexity of your claim.

You can claim refunds for diesel purchases made within 3 years from the purchase date, or 6 months from the invoice date (whichever is earlier — per CDTFA rules). Check with our team if you have older records and we'll advise on eligibility.
