The following terms are used throughout the discussion of fuel taxes. Other terms are defined in the discussion of the specific fuels to which they pertain.
Form 720-TO and Form 720-CS are information returns used to report monthly receipts and disbursements of liquid products. A liquid product is any liquid transported into storage at a terminal or delivered out of a terminal. For a list of products, see the product code table in the Instructions for Forms 720-TO and 720-CS.
The returns are due the last day of the month following the month in which the transaction occurs. Generally, these returns can be filed on paper or electronically. For information on filing electronically, see Publication 3536, Motor Fuel Excise Tax EDI Guide. Publication 3536 is only available on the IRS website.
The following discussion applies to excise tax registration requirements for activities relating to fuels only. See Form 637 for other persons who must register and for more information about registration.

Generally, diesel fuel and kerosene are taxed in the same manner as gasoline (discussed earlier). However, special rules (discussed later) apply to dyed diesel fuel and dyed kerosene, and to undyed diesel fuel and undyed kerosene sold or used in Alaska for certain nontaxable uses and undyed kerosene used for a feedstock purpose.
Diesel fuel means:
-
Any liquid that without further processing or blending is suitable for use as a fuel in a diesel-powered highway vehicle or train, and
-
Transmix.
A liquid is suitable for this use if the liquid has practical and commercial fitness for use in the propulsion engine of a diesel-powered highway vehicle or diesel-powered train. A liquid may possess this practical and commercial fitness even though the specified use is not the predominant use of the liquid. However, a liquid does not possess this practical and commercial fitness solely by reason of its possible or rare use as a fuel in the propulsion engine of a diesel-powered highway vehicle or diesel-powered train. Diesel fuel does not include gasoline, kerosene, excluded liquid, No. 5 and No. 6 fuel oils covered by ASTM specification D396, or F-76 (Fuel Naval Distillate) covered by military specification MIL-F-16884.
An excluded liquid is either of the following.
-
A liquid that contains less than 4% normal paraffins.
-
A liquid with all the following properties.
-
Distillation range of 125 degrees Fahrenheit or less.
-
Sulfur content of 10 ppm or less.
-
Minimum color of +27 Saybolt.
-
Transmix means a by-product of refined products created by the mixing of different specification products during pipeline transportation.
-
One of the two grades of kerosene (No. 1-K and No. 2-K) covered by ASTM specification D3699.
-
Kerosene-type jet fuel covered by ASTM specification D1655 or military specification MIL-DTL-5624T (Grade JP-5) or MIL-DTL-83133E (Grade JP-8). See Kerosene for Use in Aviation, later.
The tax on diesel fuel and kerosene is $.244 per gallon. It is imposed on the removal, entry, or sale of diesel fuel and kerosene. Each of these events is discussed later. Only the $.001 LUST tax applies to dyed diesel fuel and dyed kerosene, discussed later.
If the tax is paid on the diesel fuel or kerosene in more than one event, a refund may be allowed for the “second” tax paid. See Refunds of Second Tax, in chapter 2.
