  3. Work planning responsibilities involve:

    1. JOC, a group within ECS.

    2. Fuel compliance group managers.

    3. FCOs and FCAs.

  4. The Fuel Inspection Data Gathering and Analysis Project (FIDGAP), which is administered by the JOC, selects potential inspection sites in accordance with the annual fuel compliance plan and managerial direction.

    1. Sites are selected for each employee based on the employee’s starting location (i.e., residence, POD or designated parking location).

    2. Sites are also selected for Blitzes set in specific geographic locations.

    3. The database is updated based on feedback received from the field groups and new data.

Fuel Compliance Work Planning Responsibilities

    3. Each field inspection day must include at least 1 anchor point. An anchor point is a specific site selected for inspection and will include sites selected by FIDGAP, the manager or by the employee. See IRM

    4. The employee will update the plan to show what actually occurred only if the plan for the entire day changed (e.g., leave was taken instead of the planned inspection day).

  4. Approval of work plans:

    1. Group managers must review each work plan to ensure the planned work is in accordance with guidance in this section or interim guidance and managerial directives.

    2. Group managers will comment or indicate approval of the work plan on the SharePoint site.

FIDGAP Selections and Self-Identified Inspection Sites

  1. The FIDGAP sites forwarded by the manager are priority sites, but not mandatory.

  2. The employee may supplement the FIDGAP list with self-identified sites. Self-identified sites must be within the scope described in IRM

  3. The employee is expected to adjust the plan based on actual events and field observations. For instance, the employee should self-identify sites:

    1. When an inspection cannot be conducted at the FIDGAP site (e.g., out-of-business, closed). The employee should conduct other inspections in that area, if possible.


      The employee is not limited to sites with the same Activity Code as the FIDGAP site.

    2. If the employee observes an activity warranting an immediate inspection.

  4. The employee must record in the narrative workpaper in IMS the reason the site was selected for inspection. The comment will state whether the inspection site was selected through FIDGAP, manager directive such as a special project, or self-selected. If self-selected, the comment should include a statement explaining what prompted the action (e.g. “Self-selected site. I observed fuel tanks from the road.”)

Anchor Points

  1. An anchor point is a specific location at which the employee plans to perform field work.


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

  2. When identifying anchor points, employees must consider the following:

    1. FIDGAP sites and other assignments from the group manager.

    2. Leads.

    3. Self-identified potential inspection sites.

Issue Management System (IMS)

  1. IMS provides automated support for the Fuel Compliance Program.

  2. Employees and group managers should refer to the IMS guidance for specific instructional information pertaining to the use of IMS.

  3. See IRM 4.24.16 for specific requirements on inputting inspections on IMS.

    4. Update the manager concurrence to yes, once all closing actions have been completed.

IMS Standard Audit Index Numbers (SAIN) for Inspections

  1. SAINs (Activity Code variation with suffixes) are used in IMS to differentiate the types of inspection activities. Numerical suffixes are used with certain SAINs to further distinguish the type of inspection.

  2. SAIN 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 516 is used to record all wholesaler and retailer inspections. When selecting and entering the inspection issue into IMS, the following list of alpha 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.

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

  4. SAIN 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 alpha 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 IRS Commissioner to be used as a designated inspection site.

    2. "O" - to record all 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 518 is used to record all end-user inspections. If the state sample was secured as a result of an end-user inspection (business/company inspection), use the alpha suffix "Z" to record inspections received from a state employee as part of a fed-state agreement.

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 will not have time applied to them directly.

  4. Activity Code 515 is used to report time related to terminal inspections and biodiesel producers.

  5. Activity Code 516 is used to report time related to wholesaler, retailer and biodiesel blender 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 attending group meetings, reading procedural/technical material, preparing and attending technical/procedural conferences, completing forms, working on committees, managing records, preparing time reports/travel vouchers, general housekeeping (e.g., moving, ordering supplies and surveying space), truck maintenance, and e-mail/voice messaging system.

    2. Activity Code 730 - The time reported under this Activity Code include duties such as Combined Federal Campaign, physical examinations, Commissioner Representative duties, participation in attitude surveys (survey and meetings), NTEU (bank and official which includes time spent by designated union representatives as provided for in the union contract), Special Emphasis Program Time, mandatory briefings (e.g. Unauthorized Access (UNAX), Privacy Information Protection and Disclosure, etc.), and performance discussions with managers (e.g., time and workload reviews, etc.). Activity Code 730 is also used to record computer breakdowns and when the employee experiences problems with hardware or software that results in a loss of productivity.

  9. When experiencing computer, hardware or software issues, both requirements below must be met to charge time to Activity Code 730:

    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.

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.

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

  4. When the outreach occurs as part of an inspection, the employee must record the actions in IMS.

  5. At the conclusion of the outreach effort the group manager should be notified. The notification must include:

    1. How the outreach was identified.

    2. The audience.

    3. The topics discussed.

    4. The date it occurred.

    5. Location.

    6. Length of time.

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

  7. The group manager should monitor Activity Code 521 time and obtain explanations and details, as warranted.


  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 develop during an inspection. It is the responsibility of employees to recognize situations that potentially require a referral to other IRS operations, and promptly prepare and submit written referrals.

Referral Procedures

  1. An employee shall complete an electronic Form 5346, Examination Information Report, for any proposed IRC 6715 penalty in which information indicates at least 10,000 gallons of dyed fuel is involved in the penalty.

  2. The employee should gather the facts, and review fuel purchase records and other records to determine the historical extent of the taxpayer’s non-compliance and identify whether the 10,000 gallons threshold has been met.

  3. A group manager may approve opening an examination involving less than 10,000 gallons if the case will remain within that excise tax field group.

  4. Employees will attach to Form 5346 a document explaining the nature of the referral, if it is not fully explained in the form. A copy of Form 5346 and any supplemental document will be included in the closed IMS case file.

  5. Form 5346 and the supporting information shall be transmitted via secured e-mail to the group manager for approval. See IRM, Secure Messaging & Encryption.

  6. See IRM, Investigative Samples, for instructions on referring issues related to investigative samples.

  7. The group manager shall send all approved referrals, Form 5346 and the supporting information if any, via a secured message, to the Excise Workload Selection and Delivery (Excise WSD) mailbox at sbse.excise.wsd@irs.gov with subject line, "Lead/Information Report Request."

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 responsibility of Excise Tax Policy in collaboration with Privacy, Government Liaison and Disclosure (PGLD).

  2. The IRS has two types of agreements with states in relation to fuel inspections: fuel sampling agreements and information-sharing agreements. The two types may be combined into one agreement if the state agency that obtains and ships the fuel samples is the taxing agency with whom the IRS will share tax information.

    • In a fuel sampling agreement, the IRS agrees to accept state samples for testing at the Excise Forensics Laboratory (EFL). SB/SE Estate & Gift/Excise Tax Exam may share results from state fuel samples submitted to and tested by the EFL with state agencies; however, test results shared with state agencies may not reference the IRC 6715 penalty.

    • In an information-sharing agreement, the IRS and the state taxing agency share information on secured samples found within the state. Penalties authorized by IRC 6715 associated with these secured samples, may not be disclosed to state agencies under IRC 6103(d).

  3. Responsibilities for meeting the administrative provisions of the agreements are shared by the excise territories and Excise Workload Selection and Delivery (Excise WSD).

  4. The excise territory manager will appoint a group manager as the point of contact to address issues that may arise. As the point of contact, the manager will work with state officials, Excise WSD, Excise Tax Policy and PGLD.

  5. As the point of contact, the group manager must:

    1. Obtain copies of all current written agreements between any federal and state agencies within the 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 state fulfills its obligations.

    4. Make authorized disclosures of IRC 4041 and IRC 4081 federal tax information as provided in the written agreements. Penalties authorized by IRC 6715 associated with these secured samples, may not be disclosed to state agencies under IRC 6103(d). See IRM, Recordkeeping and Accounting for Authorized State Disclosures, for descriptions of the information disclosed to the states.

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

    6. Monitor employees' compliance with authorized disclosure and contract provisions of the agreements.

    7. Notify Excise Tax Policy when a state shows interest in entering into a fed/state agreement or when an existing agreement needs updating.

  6. If a group manager has questions about a particular agreement or experiences problems with a state, the manager should contact Excise Tax Policy. An analyst will work with the manager and PGLD to answer questions and resolve issues.

  7. Excise WSD will receive case information from states and lab testing results from EFL. WSD will:

    1. Associate the case information with the testing results.

    2. Ensure cases are input on ERCS and IMS and assigned to the appropriate excise field group.

    3. Ensure disclosure reporting documents are completed.

  8. Employees will work directly with federal and state officers. Maintaining a balance between making only authorized disclosures to those state officers and maintaining a solid working relationship is essential. Employees must at a minimum:

    1. Obtain copies of all current agreements between any federal and 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.

Recordkeeping and Accounting for Authorized State Disclosures

  1. Section 3(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 tax or non-tax systems 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 samples secured by the state.

    2. Lab results and taxpayer information for IRS secured samples found within the state. Penalties authorized by IRC 6715 associated with these secured samples, may not be disclosed to state agencies under IRC 6103(d).

  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. See IRM , Accounting Procedures, for the address to which the Form 5466-B should be sent. A copy of the form should also be sent to Excise WSD via secured email.

  5. 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 Disclosures.

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

    1. Name Control.

    2. SSN/EIN.

    3. Tax Period.

    4. Disclosure Date - date the information was shared with the state agency.

    5. Nature of Disclosure Code - Code 4.

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

    7. Purpose Code - Code 11.

    8. Accounts Desk Procedures (ADP) Source Code - Code 120.

  7. For more information on disclosures, see IRM 4.2.5, Disclosure of Official Information.

Fraud Development

  1. Employees must be alert to indicators of fuel tax evasion. See 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 owed. Tax fraud requires both a tax due and owing, along with fraudulent intent. See IRM, Definition of Fraud.

  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 and group manager will ensure jointly that they have sufficiently documented the appropriate fraud factors or information and consult with a Fraud Enforcement Advisor and the Excise Tax Policy Fraud Coordinator.

  5. Based on these consultations and any development of a plan of action, the employee and group manager will determine whether to recommend a referral to Criminal Investigation (CI).

  6. If the referral to CI is initiated, further participation by the employee may still be required. The CI request for employee assistance is made through the group manager.

  7. The manager should ensure the employee's participation and that feedback is shared on the outcome of the referral.

Bribery Awareness

  1. The Treasury Inspector General for Tax Administration (TIGTA) is primarily responsible for investigating all attempted bribery cases. See IRM, Reporting Bribery Attempts.

    • Throughputter - Within industry, the term generally means any person that stores fuel in a terminal. Under the taxable fuel regulations, however, the term is expanded to mean a person that (1) owns taxable fuel within the bulk transfer/terminal system (other than in a terminal), or (2) is a position holder. See Treas. Reg. 48.4081-1(b).

    • Transmix - A by-product of refined products pipeline operations created by the mixing of different specification products during pipeline transportation. Transmix is considered diesel fuel under IRC 4083(a)(3)(A).

    • Transmix Fractionator - An entity specializing in reprocessing "transmix" to recover separate saleable products such as gasoline and distillate fuels. A fractionation facility separates (fractions) the products in a distillation column. Many fractionators have a combination of mobile equipment and fixed facilities with the truck-based technical equipment moving between tank farms and storage sites, as business requires. Fractionators receive their raw material, transmix, in non-bulk shipments by rail car or by transport truck. Their finished product is dispensed either through a pipeline in bulk or across a rack, in a non-bulk distribution. If a fractionator produces taxable fuel it must have a Form 637 "S" registration as a refiner. If it dispenses taxable fuel over a rack, it must have a Form 637"S," Application for Registration (for Certain Excise Tax Activities), registration as a terminal.

    • Ultimate Vendor - An ultimate vendor (registered under IRC 4101) sells undyed diesel fuel or undyed kerosene tax free to a state or local government for its exclusive use, or (b) gasoline (including aviation gasoline) to a state or local government for its exclusive use, or to a nonprofit educational organization for its exclusive use.
