If you sell fuel to a city, you are probably giving the government money it does not want
Federal excise tax is paid at the terminal rack — 24.3¢ a gallon on diesel, 18.3¢ on gasoline — long before anyone knows who will burn it. When those gallons end up in a city street sweeper or a school district’s bus, that tax was never owed. Getting it back is a right, and it belongs to exactly one person.
A quarter of a million gallons is sixty thousand dollars
Take a jobber delivering undyed diesel to a county, a couple of cities, a fire district and a school district. Call it 250,000 gallons in a year — a modest number for anyone with municipal accounts.
At 24.3¢ a gallon that is $60,750 of federal excise tax that nobody in the chain ever owed. It was paid at the rack, it was buried in the price, and unless somebody files for it, it stays with the government.
The figure is an illustration, not a promise — your gallons are your gallons. But the rate is the statutory rate, and the multiplication is not difficult. Most jobbers we review have never done it.
Three ways it goes wrong
In roughly this order of cost.
-
1
You are not registered. The refund on an exempt sale belongs to the registered ultimate vendor. Without that registration nobody gets it — not you, and not your customer, because the law hands the claim to you and you cannot make it. The gallons are simply lost.
-
2
You waited. The claim has a deadline measured in weeks, not years. Past it the money is not gone, but it stops being a refund cheque and becomes a credit on a tax return you have not filed yet.
-
3
You were paid short. The IRS checks every customer on the claim against its own records and disallows the ones it cannot match or that are on the wrong footing. It writes to you — a Letter 106C naming the customers and the reason — and you have 30 days to respond. That letter arrives weeks after the smaller deposit did, addressed to whoever is on the account, and the clock runs whether or not it reaches the person who prepared the claim.
Registered ultimate vendors have a right ordinary taxpayers do not
This is not a filing convenience. It is a specific statutory privilege, and it exists because of how Congress decided to collect the fuel tax.
Why the right had to be invented
Until 1994, diesel tax was collected on sales by producers and registered wholesale distributors. That system leaked badly, so in the Omnibus Budget Reconciliation Act of 1993 Congress moved the tax to the terminal rack — effective 1 January 1994, tax is imposed when fuel is removed, and it comes out untaxed only if it is dyed.
That closed the evasion. It also meant every exempt buyer in America was now paying a tax they did not owe, buried in a price, with no way to see it. The registered ultimate vendor is the mechanism Congress built to put that right — resting on a registration regime that goes back to the restructuring of the fuel taxes in the 1980s.
What the right consists of
On the sales that qualify, the registered vendor is the only person permitted to claim. Not the buyer. Not the buyer's accountant. The city that bought the diesel cannot recover the tax on it, however plainly exempt it was — the statute assigns that claim to the vendor.
So the registration is not paperwork you do because you sell fuel. It is the thing that decides whether the money is recoverable at all. An unregistered seller is a dead end in the chain: the tax stops there and nobody downstream can reach it.
Sales to governments
Undyed diesel or kerosene to a state or local body for its exclusive use. Cities, counties, districts, transit authorities.
Sales to schools
Gasoline and aviation gasoline to a nonprofit educational organization. A separate route with its own certificate.
Buses, blocked pumps, aviation
Intercity and local buses, kerosene from a blocked pump, kerosene for aviation. Each has its own registration letter and its own rate.
One that catches almost everybody
There is no vendor claim on undyed diesel sold to a farmer. That one belongs to the farmer. The regulation is still titled as though it covers farming and has not been conformed to the statute for thirty years, so it is an easy and expensive mistake — and it is the sort of thing that decides whether a claim survives examination.
We look at your sales and tell you what is there
Send us what you already have — your sales by customer, and your registration if you hold one. We will tell you which of your customers qualify, whether you are registered for the right activities, how far back you can still reach, and what the recoverable figure looks like.
If there is nothing there, we say so. If there is, you will know roughly how much before you commit to anything, and the assessment costs you nothing either way.
Clients also get the worksheets: the claim tool reads your own exempt customer spreadsheet, works out which line every sale belongs on, checks the deadline and the thresholds, and produces the backing schedule. It runs entirely inside your browser — your customer list never reaches our server.
