Are bonds required to get a fuel tax license?

In some cases a bond is required when applying for a fuel tax license. See the Fuel Supplier License application (TC-69) for more information.

How often should I file Fuel returns?

You file all fuel taxes monthly (except IFTA and special fuel user; see motorcarrier.utah.gov).

Do I need a motor fuel license if I sell gasoline at the retail level (at the pump)?

No. Gasoline (motor fuel) is licensed at the distributor level. You must have a license if you:

  • import motor fuel from another state,
  • refine motor fuel,
  • blend motor fuel with other substances, or
  • are a gasoline wholesaler (sell to another retailer who sells the fuel to an end user).

Individuals who sell gasoline at the retail level (at the pump) only have to be licensed if they also meet distributor requirements.

I own a small service station and sell diesel fuel. Do I need a Special Fuel License?

No. Special Fuel tax is collected and remitted at the refiner level. You must have a license if you:

  • import special fuel from another state,
  • refine special fuel, or
  • blend special fuel with other substances.

Individuals who sell special fuel at the retail level (at the pump) only have to be licensed if they also meet distributor requirements.

How long should I keep my business records?

You must keep all records for at least 3 years.

Compressed Natural Gas (CNG) and Liquified Natural Gas (LNG)

How do I get a clean special fuel certificate?

Utah no longer issues clean special fuel certificates.

Who pays the fuel tax on CNG and LNG?

The fuel tax is imposed on the CNG & LNG supplier (owner or lessor of natural gas compression or LNG dispensing equipment).

Can I buy CNG or LNG tax free?

CNG or LNG buyers can give form TC-721CNG, Exemption Certificate for Compressed Natural Gas, to the natural gas supplier. This certificate exempts all natural gas purchases from sales tax, CNG or LNG tax and municipal energy sales and use tax at the time of purchase.

Note: Buyers must have a fuel tax account, sales and use tax account and a municipal energy sales and use tax account to report:

  • Fuel taxes for CNG
  • Use tax for residential and commercial uses of natural gas
  • Municipal energy sales and use tax

Diesel And Bio-Diesel

How are diesel and bio-diesel fuels taxed?

Clear diesel and bio-diesel are taxed as special fuels at the standard rate.

What is the difference between dyed and clear diesel?

Clear diesel is subject to fuel tax, but not sales tax and is intended for the operation of motor vehicles on public roadways.

Dyed diesel is not subject to fuel tax, but is subject to sales and use tax. It is intended for use in:

  • Construction equipment
  • Farm equipment
  • Recreational vehicles used off road
  • Generators
  • Heating units
  • Other equipment and machinery

Dyed diesel is not intended for use in cars, trucks or other vehicles driven on the road. Using dyed diesel to operate motor vehicles on public roadways is subject to federal and state penalties. See §59-13-320.5. Dyed diesel used for off-highway purposes is subject to sales tax rather than fuel tax.

What is off-highway use?

Off highway is a controlled area not generally open to the public. See Tax Commission Rule R865-4D-2.

How do I report someone who is using dyed diesel to operate a motor vehicle illegally?

Give the following information to the Utah State Tax Commission and the Internal Revenue Service (IRS):

  • Name and address of the person or business
  • Taxpayer identification number (FEIN or SSN) if known
  • Brief description of the alleged violation
  • Your name, address and daytime telephone number
  • How you became aware of the situation or got the information

Contact the Utah State Tax Commission in writing or by phone (fraud, waste and abuse hotline at 801-297-6719). Send IRS form 3949A, Information Referral, to the IRS.

Fuel Tax, Sales & Use Tax And Fuel Tax Refunds

When does fuel tax apply vs. sales and use tax?

Fuel tax is assessed on fuel used for motor vehicle operation on Utah public highways or waterways and on fuel used in aircraft.

Some fuel types, entities using fuel, or uses of fuel are exempt from fuel taxes. However, sales and use tax then applies unless the product, entity, or use is also exempt from sales and use tax.

Exempt fuel types include:

Exempt entities include:

  • Federal and state government agencies and their subdivisions
  • Certain Native American groups

Exempt uses of fuel include:

  • Fuel exported from Utah
  • Some cases where fuel is lost through destruction or re-refining.
  • Commercial agricultural production (see administrative rule R865-13G-8)
  • Special fuels used in machinery and equipment not registered (and not required to register) for highway use
  • Special fuels used to operate a motor vehicle off highway
  • Special fuels used to operate a power take-off unit on a vehicle
