Structure of Fuel Compliance Program

  1. This section discusses basic procedures, guidelines and requirements for use by employees and fuel compliance managers in administering Fuel Compliance Program operations.

  2. The Fuel compliance IRM consists of the following sections:

    IRM Title
    4.24.13 Overview of Fuel Compliance Program
    4.24.14 Excise Fuel Compliance Safety, Uniform, and Motor Vehicle Requirements
    4.24.15 Excise Fuel Compliance Inspection, Sampling and Shipping
    4.24.16 Excise Fuel Compliance Report Writing, Case Closing, and Appeals Procedures

  3. The Fuel Compliance Program follows a three pronged approach to compliance activities:

    1. activities pertaining to dyed diesel fuel,

    2. activities pertaining to other taxable fuels, and

    3. activities pertaining to taxpayer education and outreach.

  4. Employees are geographically located to administer laws and regulations that pertain to fuel distribution in the United States. To ensure voluntary compliance with fuel tax laws, a variety of taxpayer contacts are made.

  5. Employees use a variety of tools and techniques to ensure taxable fuel in the fuel distribution system is properly taxed and dyed. Employees are directly responsible for assertion of penalties and tax when instances of non-compliance are identified.

  6. Employees are also responsible for supporting excise fuel tax compliance by considering excise tax registration procedures found in IRM 4.24.2, Excise Tax Registrations, excise fuel tax examination procedures found in IRM 4.24.6, Excise Tax Examiner Responsibilities, and IRM 4.24.4, Excise Fuel Taxes Workload, Policies and Procedures, in every taxpayer contact.

  7. All compliance activities are structured around the Annual Excise Fiscal Year Work Plan.  (08-01-2013)
Organizational Structure and Responsibilities

  1. The Chief, Excise Tax Program has overall responsibility for the Excise Tax Program.

  2. The Excise Fuel Policy Manager reports directly to the Chief, Excise Tax Program and has responsibility for the development of Fuel Compliance Program policies, guidance, and procedures.

  3. The Fuel Territory Managers report directly to the Chief, Excise Tax Program, who is responsible for administering all Fuel Compliance Program field operations throughout the United States.

  4. There are two Fuel Territories; Fuel Territory East and Fuel Territory West. Each territory has responsibility for conducting the enforcement activities and meeting the goals of the Fuel Compliance Program.

  5. Each group manager reports directly to a fuel territory manager. Each group manager is responsible for operations within a specific geographic area of the United States. Responsibilities include directing and reviewing the activities of all employees in the group and controlling all day to day operations within the assigned group area.

  6. Employees report to a specific group manager. The fuel compliance officer groups are comprised of fuel compliance officers (FCO). The fuel revenue agent groups are comprised of fuel revenue agents and fuel compliance agents (FCA).

  7. The procedures found in this IRM section generally apply to both the FCA and FCO positions. The term "employees" is used throughout this section and refers to both the FCO and FCA positions. The duties are summarized below:

    1. FCO conduct inspections and outreach to promote compliance with the fuel tax laws. The inspections may result in the assertion of penalties if non-compliance is identified. The FCO also assists with the enforcement activities of other personnel within the Excise Tax Program. The assistance includes, but is not limited to, identifying potential excise tax issues and obtaining fuel samples.

    2. FCA conduct the inspections and the other activities included in the description of the FCO duties. In addition, the FCA perform examinations and compliance reviews related to fuel issues and assess any tax and penalties due as a result.  (08-01-2013)
Excise Fuel Compliance Work Plan

  1. Under the direction of the Excise Fuel Policy Manager an Excise Work Plan is developed to meet organizational plans and the strategic objectives. The Excise Work Plan is the basis for most compliance activities conducted by employees.  (08-01-2013)
Fuel Compliance Manager Work Assignment Responsibilities

  1. Fuel Territory managers are responsible for:

    1. coordinating plan delivery between the territories,

    2. reassigning responsibilities for geographic coverage to address any short or long term staffing issues, and

    3. ensuring geographic coverage is sufficient to maintain a visible presence based on the fuel activity.

  2. Group managers are required to direct compliance activities and make assignments to employees that support the Excise Work Plan and meet any "ad hoc" needs that arise during the day to day operations. Managers will use a variety of methods of assigning work and assisting the employees in work planning, such as:

    1. assignment of specific geographic counties/parishes to particular employees within the group,

    2. assignment of taxpayer specific locations to be inspected, such as identified terminals, wholesalers, retailers, end users, or others within the fuel distribution system,

    3. shifting resources and geographic assignments to ensure the same personnel do not consistently inspect the same taxpayers year after year,

    4. assignment of specific dates and locations for Blitz activities and other special projects, and

    5. requiring the use of Anchor Points. See IRM

  3. The group manager will:

    1. review and approve individual work plans prepared in advance, and

    2. review updated work plans that reflect work conducted. See IRM (7).  (08-01-2013)
Fuel Compliance Work Planning Responsibilities

  1. The focus of the Fuel Compliance Program is:

    1. The planning and execution of the manager assigned inspections,

    2. joint operations with state officers, and

    3. taxpayer education and outreach activities (see IRM

  2. Employees and managers should work jointly to ensure the focus is primarily on manager assigned inspections.

  3. Self identified inspections should be conducted in the following instances:

    1. when no managerial assigned inspections were identified for that geographic location,

    2. when the employee travels to the assigned inspection and no business activity is apparent or the entity is out-of-business (If the business is in operation, but not available the day the inspection was planned, the field employee must re-schedule the inspection for another day.), or

    3. if while traveling to and from "anchor points" or "manager assigned inspections" additional inspection locations are observed.

  4. Employees are required to prepare and maintain a written work plan. The work plan will include managerial assignments, participation in special projects, self identified inspections, and other assignments such as vehicle maintenance. The work plan will consider the priorities established by management.

  5. Employees and managers are required to use the "anchor points" (see IRM below for a definition of an anchor point) concept to achieve a balance between assigned work and work identified in the field.

  6. The work plan must be recorded in SharePoint for review by the group manager. Other supplemental written planning items are submitted to the manager for review and approval but do not replace the need for using SharePoint as the basic planning tool.

  7. If the plan for the entire day changed, the daily work plan will be updated to reflect what actually occurred. The "updated" work plan does not need to include specific taxpayer details but will identify the city, town, or county visited. If a site was an identified anchor point and an inspection was not conducted because the company was closed or is no longer in business, then the updated work plan should briefly explain why an inspection was not conducted.

  8. At a minimum, work plans should reflect the following basic components:

    1. prompt scheduling of all group manager assigned work,

    2. at least one identified anchor point for each day the employee plans to work in the field,

    3. a balance of all work assignment types in accordance with the excise fiscal year work plan,

    4. adequate geographic coverage within assigned areas,

    5. other elements such as whether overnight travel is required to efficiently complete assignments,

    6. a minimum of two weeks of planned actions, updated weekly, including planned travel, specific inspection and examination sites, truck maintenance, leave, or any other pertinent information, and

    7. updated information on what occurred, only if the plan for the entire day has changed.  (08-01-2013)
Anchor Points

  1. An anchor point is defined as any specific location that can be preplanned such as an inspection site, construction work site, taxpayer name or address within a specific geographic area.


    General references are not acceptable such as counties, cities, towns or other non-specific locations.

  2. When identifying anchor points employees should consider the following:

    1. excise fiscal year work plan,

    2. geographic coverage,

    3. assignments from the group manager, and

    4. leads or self identified potential inspection sites.

  3. At least one anchor point must be identified and entered into the employee's work plan for each day the employee plans to work in the field.  (08-01-2013)

IMS Standard Audit Index Numbers (SAIN) for Inspections

  1. SAIN numbers (activity codes) are used in IMS to differentiate the specific types of inspection activities. Suffix numbers are used with certain SAIN to further distinguish the type of inspection.

  2. SAIN number 515 is used to record all terminal inspections. To record an inspection received from a state employee as part of a Fed-State agreement, use the suffix "Z" .

  3. SAIN number 516 is used to record all wholesaler and retailer inspections. When selecting and entering the inspection issue into IMS, the following list of suffixes must be used to identify the type of inspection:

    1. "R" - to record a retailer inspection (including truck stops),

    2. "W" - to record a wholesaler inspection, and

    3. "Z" - to record an inspection received from a state employee as part of a Fed-State agreement.

  4. SAIN number 517 is used to record all designated inspection site screenings and inspections. When selecting and entering the inspection issue into IMS, the following list of suffixes must be used to identify the type of screening or inspection:

    1. "H" - to record fuel compliance inspections and screenings at any state highway inspection station, weigh station, mobile station, or other location designated by the Commissioner to be used as a designated inspection site.

    2. "O" - to record inspections and screenings at sale barns, livestock auctions, construction sites, and similar situations where vehicles operated by various entities are inspected at a single site and law enforcement officers are not needed to direct the vehicles.

    3. "Z" - to record an inspection received from a state employee as part of a Fed-State agreement, if the state sample was secured as a result of an on road inspection (designated inspection site).

  5. SAIN number 518 is used to record all end user inspections. To record an inspection received from a state employee as part of a Fed-State agreement, use the suffix "Z" , if the state sample was secured as a result of an end user inspection (business/company inspection).


    See the table below to determine whether the inspection is an end user inspection or a designated inspection site inspection.

    If ... And ... Then ...
    Employees arrive at a company’s office or yard Conducts an inspection It is an end-user inspection. Input on IMS under SAIN 518
    Employees arrive at a site (such as a construction site) Travel throughout the site inspecting diesel trucks The contacts are end-user inspections. Input on IMS under SAIN 518
    Employees arrive at a construction site Set up a designated inspection site and screen trucks that come to the field personnel The contacts are designated inspection site inspections. Input on IMS under SAIN 517O.  (08-01-2013)
Time Reporting

  1. All time (direct and indirect) must be entered into the time sheet application on IMS.

  2. Direct inspection time is entered in the section entitled "Misc. Direct Exam Time" .

  3. Fuel inspections residing on IMS will not have time applied to them directly.

  5. Activity code 516 is used to report time related to wholesaler and retailer inspections.

  6. Activity code 517 is used to report time related to designated inspection site inspections.

  7. Activity code 518 is used to report time related to end-user inspections.

  8. Activity codes 610 and 730 are used to report indirect and administrative time respectively.

    1. Activity code 610 - Time spent on technical duties that cannot be charged to a specific case or activity. Generally this includes group meetings, reading procedural/technical material, preparing and attending technical/procedural conferences, records management, preparing time reports/travel vouchers, truck maintenance, supplies and e-mail/VMS.

    2. Activity code 730 - The time reported in this item pertains to duties such as combined federal campaign, savings bonds, time spent for physicals, Commissioner Rep. duties, participation in attitude surveys (survey & meetings), NTEU (bank & official which includes time spent by designated union representatives as provided for in the union contract), Special Emphasis Program Time, computer breakdowns, and performance discussions with managers (e.g., 4502, workload reviews, etc.).

  9. Activity code 613 should be used when problems using hardware or software applications result in a loss of productivity. The following requirements must be met in order to charge time to activity code 613:

    1. a help desk ticket has been submitted and remains open, and

    2. the employee is actively engaged in the fix. This includes troubleshooting with someone to fix the system, resolving equipment and software problems, server time-outs or outages, computer problems, and participating in phone testing.  (08-01-2013)
Taxpayer Outreach and Education

  1. Customer service includes appropriate educational and outreach efforts. This supports an overall strategy to promote voluntary compliance

  2. Employees shall engage in various outreach activities such as, but not limited to:

    1. formal meetings with trade organizations and associations,

    2. participation in trade shows,

    3. meetings with state fuel inspection employees,

    4. one-on-one discussions during inspections/examinations, and

    5. calls from fuel industry stakeholders requesting information.

  3. Employees need to ensure that the group manager is aware of and has approved the first three activities listed in (2) above.

  4. Whenever possible employees should document their educational/outreach efforts on IMS. This would occur when an inspection has taken place.

  5. Any time associated with educational/outreach activities should be recorded under Activity Code 521, unless it was done at the time of the inspection.

  6. The group manager should monitor time devoted to this code and obtain explanations as warranted.  (08-01-2013)

  1. Employees are exposed to a variety of situations where direct penalty enforcement is not the only issue. Significant fuel tax issues, other excise tax issues, or other tax issues may be apparent or be developed during an inspection. It is the responsibility of employees to not only recognize potential situations that require referral to other IRS units, but also to promptly prepare and submit written referrals.  (08-01-2013)
Referral Procedures

  1. Employees shall complete an electronic Form 5346, Examination Information Report. If necessary, employees will also attach a document explaining the nature of the referral. A copy will also be included in the closed case file.

Fed/State and Fed/Fed Agreements

  1. A variety of written agreements may be developed to coordinate tax administration with other federal or state agencies. Development of these agreements is a primary responsibility of Excise Policy in conjunction with Privacy, Government Liaison and Disclosure (PGLD). Group managers are directly responsible for administering all the provisions of the federal-federal and federal-state agreements within the assigned geographical territory. To accomplish this responsibility, the manager must:

    1. Obtain copies of all current written agreements between any federal or state agencies within their geographically assigned territory.

    2. Review and familiarize themselves with all the provisions of the written agreements within their assigned geographic territory.

    3. Meet the IRS obligations stated in existing agreements and work with their state counterparts to ensure the states fulfill their obligations.

    4. Make authorized disclosures of federal information as provided in the written agreements. Disclosures typically would include making authorized disclosures of federal penalties to state taxing agencies. See IRM Record Keeping and Accounting for Authorized State Disclosures.

    5. Provide copies of the current agreements between any federal or state agency to the FCO or FCA assigned that geographical territory.

    6. Notify Excise Fuel Policy when states show interest in entering into a Fed/State agreement or when existing agreements need updating.

    7. Monitor employee compliance with authorized disclosure and contract provisions of the agreements.

  2. If a group manager has questions about a particular agreement or experiences problems with a state, the manager should contact Excise Fuel Policy. An analyst will work with the manager and the Government Liaison Office to answer questions and resolve any issues.

  3. Employees will work directly with federal and state officers. Maintaining a balance between making only authorized disclosures to those officers and keeping a solid working relationship is essential. Disclosures authorized in current agreements are written to comply with the restrictions contained within IRC 6103. Employees must at a minimum:

    1. Obtain copies of all current agreements between any federal or state agency within their geographically assigned territory.

    2. Review and familiarize themselves with all provisions of the written agreements, including the limitations of authorized disclosures.

    3. Elevate to the manager any issues or changes that should be considered.

    4. Promptly process samples received from state officers.

    5. Work cooperatively with federal and state officials within the parameters of written agreements.  (08-01-2013)
Record Keeping and Accounting for Authorized State Disclosures

  1. Subsection (c) of the Privacy Act of 1974 and IRC 6103(p)(3)(A) require the IRS to keep an accurate accounting of each disclosure of information from a tax or non-tax system of records.

  2. Though there are important differences in the various State agreements, there are generally two types of Federal Tax Information (FTI) shared with the State agencies:

    1. Lab results for State secured samples.

    2. Lab results and taxpayer information for IRS secured samples found within the state.

  3. Group managers must keep records for both types of FTI shared with a state.

  4. Group managers must report the disclosures using Form 5466-B, Multiple Records of Disclosure. The Form 5466-B is submitted on the last business day of each month in which FTI was shared with the state. The completed form should be sent to the local campus Disclosure office that has jurisdiction and also to the designated Excise Fuel Policy Analyst. the form may be submitted electronically.

  5. Form 5466-B should be completed, as follows:

    1. Name Control - self explanatory

    2. SSN/EIN - self explanatory

    3. Tax Period - self explanatory

    4. Disclosure date - date the information was shared with the State agency

    5. Nature of Disclosure Code - Code 4

    6. Stage Agency Code - See IRM 11.3.37, Exhibit 4 for a listing of State agency codes.

    7. Purpose Code - Code 11

    8. ADP Source Code - Code 120

  6. The requirement to report information and instructions for completing and submitting the Form 5466-B is detailed in IRM 11.3.37, Recordkeeping and Accounting for Disclosure.

  7. Excise Fuel Policy will monitor compliance with this reporting requirement to ensure FTI is shared accordingly with state counterparts, as stipulated in the agreements.

  8. For more information on disclosures, see also IRM 4.2.5.  (08-01-2013)
Third Party Contacts

  1. Section 3417 of the IRS Restructuring and Reform Act of 1998 (RRA 98) requires that the IRS provide reasonable notice to a taxpayer before contacting third parties with respect to the determination or collection of that taxpayer’s tax liability. Section 3417 was incorporated as IRC 7602(c) Notice of Contact of Third Parties.

  2. See IRC 7602(c) and Treas. Regs. section 301.7602-2 Third Party Contacts

  3. If the determination is made that employees will contact third parties to obtain information relevant to a taxpayer's tax liability, employees are required to give the taxpayer notice that these contacts will be made. Publication 1 (May 2005 revision and any subsequent revisions containing the general notice of third party contact) must be used to give advance notice of third party contacts to the taxpayer.

  4. After issuing Publication 1, employee should document the IMS file with the method and date of delivery.

  5. Form 12175, Third Party Contact Report Form, is used to report third party contacts.

  6. The taxpayer can waive the rights under IRC 7602(c) and authorize the IRS to contact a specific third party by signing Form 12180, Third Party Contact Authorization Form. If a taxpayer authorizes the IRS to contact a third party, Form 12175 does not need to be completed. See IRM

  7. See IRM and IRM for current instructions for making third party contacts and recording the contacts in compliance with IRC 7602(c).

  8. Guidance specific to the FCO/FCA position is included in the table below:

    If an FCO/FCA... And ... Then a Third Party Contact...
    Obtains information during an inspection Makes a referral to an excise tax group Has not been made.
    Conducts a terminal inspection Wants to obtain a sample of fuel from a transport not owned by the terminal and will initiate the contact with the driver of the transport Will be made. A Publication 1 must be issued to the taxpayer prior to the contact with the third party.
    Finds a violation of IRC 6715 The taxpayer states it was someone else's fault Will be made. A Publication 1 must be issued to the taxpayer prior to contact with the third party.
    Conducts an inspection at a fuel wholesaler Asks to look at a list of customers who have purchased dyed product Has not been made.

    Obtains samples from a state or information regarding potential inspection candidates Employee uses the information to propose an IRC 6715 penalty or conduct an inspection Has not been made.
    Receives an unsolicited tip Uses the information to plan and conduct an inspection Has not been made.  (08-01-2013)
Fraud Development

  1. Employees must be alert to indicators of fuel tax evasion. See specific sections of IRM 25.1, Fraud Handbook, for guidance on recognizing and developing a fraud case.

  2. Tax fraud is an intentional wrongdoing on the part of a taxpayer, with the specific purpose of evading a tax known or believed to be owing. Tax fraud requires both a tax due and owing and fraudulent intent. See .IRM for more information.

  3. When employees encounter behavior or indicators of fraud, they shall immediately consult with their group manager to determine the proper course of action.

  4. The employee's and their group manager will jointly ensure that they have sufficiently documented the appropriate factors or information and consult with a Fraud Technical Advisor (FTA) and the Excise Tax Policy Fraud Coordinator.

  5. Based on these discussions and any further development or plan of action, the employee and group manager determine whether to recommend that the case should be referred to Criminal Investigation.

  6. If the referral to Criminal Investigation is initiated, further participation by the employee may still be required. The request to have an employee assist is made through the group manager.

  7. Manager's should ensure they receive feedback on the outcome of the referral and the employee's participation.  (08-01-2013)
