The tax on inland waterways fuel use applies at the rate listed on Form 720. This is in addition to all other taxes imposed on the sale or use of the fuel.
Tax applies to liquid fuel used in the propulsion system of commercial transportation vessels while traveling on certain inland and intracoastal waterways. The tax generally applies to all types of vessels, including ships, barges, and tugboats. The leaking underground storage tank (LUST) tax must be paid on any liquid fuel used on inland waterways that is not subject to LUST tax under section 4041(d) or 4081. For example, Bunker C residual fuel oil is subject to the LUST tax.taxmap/pubs/p510-011.htm#en_us_publink1000116933
Inland and intracoastal waterways on which fuel consumption is subject to tax are specified in section 206 of the Inland Waterways Revenue Act of 1978, as amended. See Regulations section 48.4042-1(g) for a list of these waterways.taxmap/pubs/p510-011.htm#en_us_publink1000116934
Commercial waterway transportation is the use of a vessel on inland or intracoastal waterways for either of the following purposes.
- The use is in the business of transporting property for compensation or hire.
- The use is in transporting property in the business of the owner, lessee, or operator of the vessel, whether or not a fee is charged.
The operation of all vessels meeting either of these requirements is commercial waterway transportation regardless of whether the vessel is actually transporting property on a particular voyage. However, see Exemptions,
later. The tax is imposed on fuel consumed in vessels while engaged in any of the following activities.
- Moving without cargo.
- Awaiting passage through locks.
- Moving to or from a repair facility.
- Dislodging vessels grounded on a sand bar.
- Fleeting barges into a single tow.
- Maneuvering around loading and unloading docks.
Liquid fuel includes diesel fuel, Bunker C residual fuel oil, Other Fuels, and gasoline. The tax is imposed on liquid fuel actually consumed by a vessel's propulsion engine and not on the unconsumed fuel in a vessel's tank. taxmap/pubs/p510-011.htm#en_us_publink1000116936
The tax applies to all taxable liquid used as a fuel in the propulsion of the vessel, regardless of whether the engine (or other propulsion system) is used for another purpose. The tax applies to all liquid fuel consumed by the propulsion engine even if it operates special equipment by means of a power take-off or power transfer. For example, the fuel used in the engine both to operate an alternator, generator, or pumps and to propel the vessel is taxable.
The tax does not apply to fuel consumed in engines not used to propel the vessel.
If you draw liquid fuel from the same tank to operate both a propulsion engine and a nonpropulsion engine, determine the fuel used in the nonpropulsion engine and exclude that fuel from the tax. IRS will accept a reasonable estimate of the fuel based on your operating experience, but you must keep records to support your allocation. taxmap/pubs/p510-011.htm#en_us_publink1000116937
The tax applies to fuel consumed by a vessel crossing the boundaries of the specified waterways only to the extent of fuel consumed for propulsion while on those waterways. Generally, the operator may figure the fuel so used during a particular voyage by multiplying total fuel consumed in the propulsion engine by a fraction. The numerator of the fraction is the time spent operating on the specified waterways and the denominator is the total time spent on the voyage. This calculation cannot be used where it is found to be unreasonable. taxmap/pubs/p510-011.htm#en_us_publink1000116938
Tax is imposed on liquid fuel used in the propulsion system of a vessel. See Form 720 for the tax rate.
The person who operates (or whose employees operate) the vessel in which the fuel is consumed is liable for the tax. If a vessel owner (or lessee) contracts with an independent contractor to operate the vessel, the independent contractor is the person liable for tax, regardless of who purchases the fuel. The tax is paid with Form 720. No tax deposits are required. taxmap/pubs/p510-011.htm#en_us_publink1000116939
Certain types of commercial waterway transportation are excluded from the tax. taxmap/pubs/p510-011.htm#en_us_publink1000116940
Fuel is not taxable when used by a fishing vessel while traveling to a fishing site, while engaged in fishing, or while returning from the fishing site with its catch. A vessel is not transporting property in the business of the owner, lessee, or operator by merely transporting fish or other aquatic animal life caught on the voyage.
However, the tax does apply to fuel used by a commercial vessel along the specified waterways while traveling to pick up aquatic animal life caught by another vessel and while transporting the catch of that other vessel. taxmap/pubs/p510-011.htm#en_us_publink1000116941
Fuel is not taxable when used by a vessel designed primarily for use on the high seas if it has a draft of more than 12 feet on the voyage. For each voyage, figure the draft when the vessel has its greatest load of cargo and fuel. A voyage is a round trip. If a vessel has a draft of more than 12 feet on at least one way of the voyage, the vessel satisfies the 12-foot draft requirement for the entire voyage. taxmap/pubs/p510-011.htm#en_us_publink1000116942
Fuel is not taxable when used by vessels primarily for the transportation of persons. The tax does not apply to fuel used in commercial passenger vessels while being operated as passenger vessels, even if such vessels also transport property. Nor does it apply to ferryboats carrying passengers and their cars. taxmap/pubs/p510-011.htm#en_us_publink1000116943
Fuel is not taxable when used in tugs to move LASH and SEABEE ocean-going barges released by their ocean-going carriers solely to pick up or deliver international cargoes.
However, it is taxable when any of the following conditions apply.
- One or more of the barges in the tow is not a LASH barge, SEABEE barge, or other ocean-going barge carried aboard an ocean-going vessel.
- One or more of the barges is not on an international voyage.
- Part of the cargo carried is not being transported internationally.
No tax is imposed on the fuel used in a vessel operated by a state or local government in transporting property on official business. The ultimate use of the cargo must be for a function ordinarily carried out by governmental units. An Indian tribal government is treated as a state only if the fuel is used in the exercise of an essential tribal government function.
All operators of vessels used in commercial waterway transportation who acquire liquid fuel must keep adequate records of all fuel used for taxable purposes. Operators who are seeking an exclusion from the tax must keep records that will support any exclusion claimed.
Your records should include all of the following information.
- The acquisition date and quantity of fuel delivered into storage tanks or the tanks on your vessel.
- The identification number or name of each vessel using the fuel.
- The departure time, departure point, route traveled, destination, and arrival time for each vessel.
If you claim an exemption from the tax, include in your records the following additional information as it pertains to you.
- The draft of the vessel on each voyage.
- The type of vessel in which you used the fuel.
- The ultimate use of the cargo (for vessels operated by state or local governments).
