For additional information about the TBOR, see Taxpayer Bill of Rights, on IRS.gov.
What is a Referral?
21.3.5.2 (10-01-2019) What is a Referral? A written/electronic referral is initiated (in limited instances) when a taxpayer inquiry cannot be resolved: While the taxpayer is still on the telephone In the Taxpayer Assistance Center (TAC) By the close of business/or the end of your tour of duty (TOD) on the day contact is made Note: Do not advise the caller the reason for the referral is the end of your TOD. Apologize to the caller and explain that additional research is needed to answer their question. Offer to prepare a referral and advise the taxpayer of the 30 day timeframe for a response. If the taxpayer does not want to wait the 30 days, suggest they call back and provide the hours of operation. The initial contact may be received in person or by telephone. Note: See IRM 21.3.5.4.2.1, e-4442 Electronic Transmission, for information and requirements to use e-4442 application on Account Management Services (AMS). A written/electronic referral is initiated on Form 4442, Inquiry Referral, or electronic 4442 (e-4442). Most referrals are account referrals. These referrals are either: Kept in the office where they are initiated Sent to another office/campus/function due to a specific IRM reference A correct referral has several steps: Identify the taxpayer's issue by listening to the taxpayer and asking probing questions. Determine the action needed to resolve the issue, research Integrated Data Retrieval System (IDRS) and appropriate reference material. Determine if you are authorized to complete the action. If you are not authorized, determine what function is authorized. Take appropriate action. Note: Unless directed by a specific IRM other than IRM 21.3.5, Taxpayer Inquiry Referrals Form 4442, do not prepare a referral (Form 4442) if the taxpayer is calling only to check on the status of their refund/claim and does not provide additional information to assist in resolving the case. If you have access to Account Management Services (AMS), add an issue. If you do not have access to AMS, input history item on IDRS. It is not required to input a remark on both systems.
What is Not a Referral
21.3.5.2.1 (02-01-2012) What is Not a Referral An inquiry resolved on-line or by the end of your tour of duty (TOD) is not a referral. A fax from a taxpayer or any written correspondence, whether it is an initial inquiry or related to an existing case, is not a referral. Providing the taxpayer with a telephone number or directing them to a Taxpayer Assistance Center (TAC) is not a written referral (as defined in this IRM section). Reminder: Never provide the taxpayer with a telephone or fax number marked for "internal use only" . An informant call is not considered a referral. If a taxpayer indicates they have information concerning an Abusive Tax Shelter, provide the taxpayer with the number of the Abusive Tax Shelter Hotline, 1-866-775-7474.
Referral Research
21.3.5.3 (05-28-2025) Referral Research Perform complete research prior to making a referral. Use the appropriate reference material; (IRMs, publications, tax packages/forms, Interactive Tax Law Assistant (ITLA), Integrated Data Retrieval System (IDRS), Correspondence Imaging Inventory (CII), Accounts Management Services (AMS) narrative(s), for current or previously worked related issue(s), and the e-4442 application on AMS to resolve inquiries. Use the Servicewide Electronic Research Program (SERP) to research on-line. SERP provides on-line access to: IRMs Document 6209 Tax law publications Tax forms Lexis-Nexis IRM updates Alerts Telephone and fax numbers Other related resources
Referral Procedures
21.3.5.4 (05-28-2025) Referral Procedures Inform the taxpayer a referral has been completed in response to their inquiry and always provide the taxpayer with an expected response time. Use the time frame listed in the specific IRM requiring the referral. If a time frame is not listed, tell the taxpayer they will hear from us within 30 calendar days. Stress to the taxpayer that we make every effort to respond as quickly as possible. Reminder: The timeframe provided to the taxpayer is for contact or resolution. Note: See IRM 13.1.7, Taxpayer Advocate Service (TAS) Case Criteria, to determine if the inquiry meets Taxpayer Advocate Criteria. Refer to IRM 21.1.3.18, Taxpayer Advocate Service (TAS) Guidelines, for additional information.
When to Prepare a Referral
21.3.5.4.1 (05-28-2025) When to Prepare a Referral Prepare Form 4442/e-4442 Inquiry Referral in the following circumstances: You are not trained to perform the needed resolution. A subject specific IRM section directs you to prepare Form 4442/e-4442, Inquiry Referral. See Exhibit 21.3.5-1, Referral IRM Research List, for a list of possible referrals with IRM references. Note: The subject specific IRM is the controlling IRM for the topic. Example: IRM 21.4.1, Refund Research, is the subject specific IRM for Refund Inquiry. No other IRM can override procedures concerning refund inquiry. An open control prevents you from taking action and is not for a CII case, or you do not have access to CII. See IRM 3.13.5.87, Integrated Data Retrieval System (IDRS) Office Identifiers, to determine where the open control is located. Unless directed by the subject specific IRM, an unassigned control may be placed in B status to take the necessary actions. Once actions are taken, restore the unassigned control back to its original status. Note: If a EEFax number is not provided in the IRM section requiring the referral, use Form 4442 Referral Fax Numbers on SERP under the Who/Where page for a listing of EEFax numbers by site and function. Use the drop down menus to make your selections, then click submit to view the results. Reminder: Access to CII in a research role (view only) is available for all AM and TAC employees. You must access CII every 45 days to remain active. Loss of access should not be used as the reason for creating a referral. If the open control is for a CII case, you have access to CII and the taxpayer provides additional information to assist in resolution of the case or the timeframe for working the case has passed, do not initiate a referral. Add the information to the CII case as a Case Note. Refer to IRM 21.5.1.5, Correspondence Imaging Inventory (CII) Procedures, for more information. See IRM 21.5.2.3(6), Adjustment Guidelines - Research, for additional information about open controls.
How to Prepare a Referral
21.3.5.4.2 (05-28-2025) How to Prepare a Referral All referrals are prepared in Account Management Services (AMS) if you have AMS access, and the question is an account inquiry. A complete Form 4442/e−4442 Inquiry Referral, must have the following entries: Box 1, Employee's Name Box 2, ID Number Box 3, Received Date and Time Box 4, Location Box 5, Referring To Box 6, Date and Time Box 7, Manager's Signature Box 8, Taxpayer's Name on Return Box 9, TIN Box 13, Current Address Box 15, Form(s) (IMF optional) Box 16, Plan/Report # (MFT) Box 17, Tax Period Box 18, Processing Campus (IMF optional) Box 19, Date Filed (IMF optional) Box 21, Refund/Balance Due Box 22, Caller (Caller's name) Box 24, Taxpayer's Telephone Number(s) – Include Best Time To Call and Preferred Language Part III, Section B, Taxpayer Inquiry/Proposed Resolution Note: Boxes 1 through 13 are filled in automatically when using e-4442. Reminder: Entries in the remaining fields are required as appropriate. Note: AMS e-4442 does not show box numbers when creating a referral, but the same information/entries are required on both Form 4442 and e-4442. The above bullet list uses the box numbers and titles for reference. Include in Part III, Section B, Taxpayer Inquiry/Proposed Resolution, the IRM reference directing the referral, the reason you are making the referral, a complete description of the taxpayer's issue, and the time frame provided to the taxpayer. When a subject specific controlling IRM for the referral is not located and referring to an open control on a non-CII case, include the IDRS number of the employee assigned the open control. Caution: Do not refer to a clerical unit or holding number. Clerical assignee numbers represent workflow designations rather than individual employees. These non-employee assignee numbers are frequently distinguished by zeros in the last five digits of the employee number; however, numbers other than zero may also be used. Lists of these numbers are provided in either campus IDRS bulletins or the IDRS MESSG file. If the receiving area does not have AMS, the reviewer must print the referral (print to pdf) and EEFax it to the appropriate area. For Form 4442 requiring faxing, you must include the EEFax number to the location where the referral is being sent, and the IRM reference used for the referral. If a EEFax number is not provided in the IRM section requiring the referral, use Form 4442 Referral Fax Numbers. Caution: Include only the facts required to resolve the taxpayer's issue. Do not include personal opinions. Note: See IRM 21.3.5.4.1, When to Prepare a Referral, and IRM 21.5.2.3, Adjustment Guidelines – Research, for reasons for making referrals. Always include your full name in box 1 and your employee identification number (or your IDRS number) in block 2 on a paper referral. When the required information is automatically generated by AMS, it is not necessary to reinput the information in the required field. Note: If you have access to Integrated Data Retrieval System (IDRS), you must use your IDRS number. Form 4442, Inquiry Referral, requires review by the manager, referral coordinator, or designated lead. Verify Box 7 contains an approval signature. Reminder: Erroneous referrals (e.g., misrouted, incomplete or missing information) are rejected by the receiving office through the Form 4442 Erroneous Referral Coordinators, back to the originators site. The e-4442 application contains a drop-down menu for IRM required referrals. When you pick a referral type from this menu an IRM reference will automatically post to the Form 4442, but not to AMS. Always verify the IRM reference on the referral is correct for the reason you are initiating the referral. You must manually input the IRM reference on the referral in Part III, Section B, Taxpayer Inquiry/Proposed Resolution. Refer to IRM 21.1.3.18, Taxpayer Advocate Service (TAS) Guidelines, for additional requirements if referring a case meeting TAS criteria. See IRM 13.1.7, Taxpayer Advocate Service (TAS) Case Criteria.
e-4442 Electronic Transmission
21.3.5.4.2.1 (10-22-2015) e-4442 Electronic Transmission Use the Electronic Form 4442/e-4442 application to prepare, electronically route, review, and work Form 4442/e-4442 referral inventory.
Preparing an e-4442/4442
21.3.5.4.2.1.1 (05-28-2025) Preparing an e-4442/4442 Research Account Management Services (AMS) to determine if a duplicate referral already exists on the system. The system does not allow the creation of a second referral if one already exists on the system which was created in the past seven (7) calendar days and meets all the following criteria: Taxpayer Identification Number (TIN) Master File Tax (MFT) Tax Period Function Issue Site To create a referral on AMS under Forms, select New e-4442 under the Inventory column, then select/add an issue. The e-4442 will populate many of the Form 4442 fields for you. AMS will populate a unique 8-digit case number for each e-4442. The case number may be used when leaving AMS narratives of action(s) related to the referral (e.g., switch to print for faxing, reviewer rejecting to originator for correction). You must manually complete all required fields that are not populated by e-4442. Route e-4442s to one of three inventory queues listed below. Personal Inventory - Referrals resolved by the close of business (COB). Items in personal inventory move automatically to the manager's review folder if they are not resolved. Once reviewed and accepted by the manager, inventory items are directed to the In-House inventory by the manager. Example: You are waiting on a fax from a taxpayer, and you expect to close the case by COB, prepare and route the e-4442 to your personal inventory using "Required Systems Unavailable" as the reason for the referral. If time and phone schedules permit, return the call the same day when required systems become available. The referral converts to an in-house referral if not resolved by COB. In-House Inventory - Referrals prepared when IDRS/AMS/Computer Files On-Line (CFOL) are down, complex issue, lack of training, supervisor/lead call back, or additional research needed. Example: You receive a call on a complex issue that you have not received training on. You prepare and route an e−4442 to the in−house inventory. Note: Do not use "Other (write-in)" as the category for an In-House Referral unless IRM directed. IRM-Directed Referral Inventory - Referrals written per instructions in an IRM. See Exhibit 21.3.5-1, Referral IRM Research List, for a listing of IRM-directed referrals. Research the subject specific IRM reference to determine if your issues meet the referral criteria and to determine how to route the referral. Example: You receive a refund inquiry on an account with an injured spouse claim. You prepare and route an e−4442 to the IRM-directed referral inventory per the procedures in IRM 21.4.6.6.4, Injured Spouse Inquiries. Example: You receive an inquiry about the status of an amended claim. The account has a -A freeze, the timeframe has expired, and there is no open control on IDRS. You would select IRM and -A freeze as the reason for the referral. Use the drop-down menus to route IRM-directed referrals to the appropriate function, site, and to direct In-House referrals to the correct queue. Note: Use "Other (write-in)" as the category for an IRM-Directed Referral only when the category is not available in the drop-down menu. EEFax IRM-directed referrals to an area that does not have AMS access. The e-4442 application allows you to print the referral (print to pdf) instead of transmitting electronically. If faxing the referral, Part III, Section B, Taxpayer Inquiry/Proposed Resolution, you must include the EEFax number and location where the referral is being sent, and the IRM reference used for the referral. If a fax number is not provided in the IRM section requiring the referral, use Form 4442 Referral Fax Numbers on SERP under the Who/Where page for a listing of EEFax numbers by site and function. Caution: For non-AM employees, since a request for a change/reinstatement of a Direct Debit Installment Agreement (DDIA) must be received by Compliance Service Collection Operation (CSCO) a minimum of 10 business days before the payment date, all Forms 4442 sent for issues relating to a DDIA are reviewed by the manager or manager's designee within 24 hours. See IRM 5.19.1.6.4.13.2, Taxpayer Problems with DDIA. Forms 4442 are rejected from CSCO if not received timely. Manager or manager's designee must review referrals within three (3) business days from the date the referral was initially created or resubmitted for review. The reviewer must verify all required data elements are present. Electronically routed referrals must contain an explanation, timeframe, and a valid linked IRM. Referrals sent by EEFax, Part III, Section B, Taxpayer Inquiry/Proposed Resolution, must contain an explanation, timeframe, IRM reference, EEFax number and location. Reminder: Do not submit a referral for missing command codes, or loss of access to CII. If a case is open on CII see IRM 21.3.5.4.1(2), When to Prepare a Referral. Caution: Erroneous referrals will be rejected by the receiving office back to the originator. The initiating employees must take action on rejected referrals within two (2) business days of the case being rejected.
Pre-existing Form 4442/e-4442
21.3.5.4.2.1.1.1 (10-01-2024) Pre-existing Form 4442/e-4442 If an e-4442, Inquiry Referral, already exists on Account Management Services (AMS), review the history and leave notes (on the case notes tab) to assist in resolving the case when the case meets any of the criteria listed below: Assigned Requires additional research IRM required inventory of another function or site Refer to the table below when receiving a call concerning an account inquiry with a pre-existing Form 4442/e-4442. Row If... And... Then... 1 There is an open control on Integrated Data Retrieval System (IDRS) It has not yet been assigned Explain to the caller that their inquiry has been received but the case has not been assigned to an assistor. The caller can expect contact within 30 days from the date of receipt. 2 There is an open control on IDRS It has been assigned Explain to the caller that they can expect contact within 30 days of the received date. 3 There is an open assigned control on IDRS The normal processing timeframe has expired Determine if the case meets Taxpayer Advocate Service (TAS) criteria, as outlined in IRM 21.1.3.18, Taxpayer Advocate Service (TAS) Guidelines. 4 There is an open assigned control on IDRS the normal processing timeframe has expired AND it does not meet referral criteria to TAS Apologize for the additional delay Notate the account Advise them we have notated the account and will notify them when the issue is resolved Caution: Do NOT generate another Form 4442/e4442, suggest they call back to check the status, or provide any expected timeframe of resolution 5 There is a closed control on IDRS Action was taken to cause issuance of a notice or letter The caller should be advised to expect correspondence within two weeks of the closing date. Never send a referral to an assistor after a case has been closed. Reminder: Always leave a case note on the e-4442 when the taxpayer makes a subsequent contact if the case is open. Work and close the case on-line if the case meets all the following criteria: Open Unassigned In an in-house inventory queue You can resolve and close the case immediately Note: Leave a case note explaining the action taken to resolve issue. Example: See the table below for examples of when this may occur. If referral was created due to And Then IDRS being down IDRS is now available Resolve and close the case. Lack of training Trained employee receives the subsequent contact Resolve and close the case. Additional research needed Information available to employee receiving subsequent contact Resolve and close the case. Complex Issue Employee receiving subsequent contact able to resolve immediately on–line Resolve and close the case.
Controlling Referrals
21.3.5.4.2.2 (11-16-2023) Controlling Referrals Control all referrals on Integrated Data Retrieval System (IDRS). Use activity code "4442XX." The XX represents the campus/office/file location code of the site where the referral will be worked. When creating an e-4442, Inquiry Referral, the system should automatically generate the Control and Activity Code. Use case status code "A" if you are preparing a referral and will work it as a personal referral. If you are preparing an e-4442, the control automatically generates. Use case status code "B" if you are preparing a paper referral to be placed in an In-House Inventory. When creating an e-4442, the system automatically generates to case status code "B" for In-House Inventory. When an employee selects next case from the e-4442 system (In-House or IRM required), the case will reassign to the selecting employee in case status code "A" . Reminder: Ensure employees are accurately profiled to receive and work e-4442 inventory. Use case status code "C" if you are preparing a paper referral and the IRM specifies you are to send it to another office/campus/function or closing a case. When creating an e-4442, the system controls the case-to-case status code "B" and assign case to the receiving site's generic number. When closing a case on the e-4442 system, the system automatically closes the control on IDRS. Note: If the reviewer of the e-4442 determines the form is in error, the reviewer must manually update the case status code and category code. These same procedures apply to e-4442s in the case worker's personal inventory and not closed by close of business (COB). Use the following category codes to identify referrals as appropriate: TWRA-Telephone generated Written Referrals (ACA) TWRR-Telephone generated Written Referrals (Refund) TWRC-Telephone generated Written Referral (Collections) TWRO-Telephone generated Written Referrals (Other) MISC - Use this code anytime you are referring a paper Form 4442 to another office/campus/location. If the case is in inventory, you must manually change the category code to "MISC" and close the control base before referring the paper case. If the case is prepared and being referred to another office/campus/location while on the phone (not going into site inventory), use category code "MISC" and case status code "C" . Cases meeting e-4442 criteria are automatically assigned to category code "TWRO" and case status code "B" when electronically sending to another site. Note: Use the above category codes to identify referrals. Do not use them with unsolicited correspondence.
Required Systems Unavailable
21.3.5.4.2.3 (01-10-2025) Required Systems Unavailable When access to systems (e.g., IDRS, CFOL, SERP, etc.) required to resolve a telephone inquiry are unavailable, take the following actions: Exception: If Interactive Tax Law Assistant (ITLA) is unavailable you must perform complete research using the appropriate reference material. Use the Servicewide Electronic Research Program (SERP) for on-line access to IRMs, publications, tax packages/forms, Job Aids, IRM updates, Alerts, telephone and fax number and other resources instead of creating a tax law referral. Reminder: In general, loss of a command code falling off your profile or loss of CII access should not be used as the reason for a referral. You must access CII every 45 days. See IRM 21.5.1.5, Correspondence Imaging Inventory (CII) Procedures, for more information. Advise the caller that, at this time, the systems required for you to assist them are unavailable. Apologize for the inconvenience. Note: Answer any general questions and remind taxpayers of the self-help methods available at IRS.gov. Provide the Hours of Operation located on SERP. Suggest to the caller that they try calling back at a later time. If the caller agrees, do not prepare a referral. If the caller prefers that we return their call, take the following actions: Complete Form 4442/e-4442. Advise caller that we will contact them within 30 days. Reminder: Be sure to accurately document the contact's name, telephone number(s) and the best time to call. Place the referral in your personal inventory queue. If time and phone schedules permit, return the call the same day when required systems become available. The referral converts to an in-house referral if not resolved by COB. CSRs using screen reader adaptive software who receive an EEFax in a format the software will not read, should contact their manager. If the manager is not available, prepare an In-House e-4442 referral with "Technical Issues" as the reason. Advise the caller the fax cannot be read due to technical issues and the caller will receive a call back within the specified timeframe for the issue. Do not transfer the caller to your agent group.
How to Transmit/Route Referrals to Another Office/Function
21.3.5.4.3 (05-28-2025) How to Transmit/Route Referrals to Another Office/Function Transmit referrals electronically through the e-4442 application or faxed/hand carried to the referral point within four (4) days. Reminder: Use of eFax, when available, is used in lieu of manual faxing. Form 4442 Referral Fax Numbers are available on SERP under the Who/Where page. Never transmit/route a referral to a functional area unless directed by the IRM. If you are unable to determine where an employee is located, refer to the IUUD:IDRS UNIT & USR DATABASE and Discovery Directory. Exception: When the IDRS unit number begins with "11" , use the Manager Address and not the Home Campus address to prevent misrouted and/or erroneous referrals. When faxing Form 4442, Inquiry Referral, you must use the EEFax number provided in the IRM if one is available. If a EEFax number is not available, refer to the EEFax number for the appropriate function shown on the Form 4442 Referral Fax Numbers on the SERP Who/Where page. Note: Do not use the Form 4442 Erroneous Referral Coordinators list. Only erroneous referrals are faxed to the coordinator. Note: If a EEFax number is not working, elevate to your local Planning & Analysis (P&A) so any system issues may be identified and resolved, or a correct number can be provided. Leave an AMS history note of the action(s) when eFaxing a referral to indicate the referral has been closed from AMS inventory. Include the Form 4442/e-4442 case number. Example: F4442, case number 12345678, approved, EEFaxed per referral and closed. Most IMF IRM-directed 4442s created by Puerto Rico are referred to the Brookhaven Campus for resolution if the specific IRM directs the referral to be routed to the campus AM paper function within your directorate. Exception: -A freeze and Merge Request referrals are worked at the Puerto Rico campus. Routing of IMF Form 4442 referrals, involving BMF campuses and remote BMF sites: All IMF IRM-directed 4442s created by Cincinnati and Buffalo are referred to the Fresno Campus for resolution if the specific IRM directs the referral to be routed to the campus AM paper function within your directorate. All IMF IRM-directed 4442s created by Ogden and Oakland are referred to the Kansas City Campus for resolution if the specific IRM directs the referral to be routed to the campus AM paper function within your directorate. Routing of BMF Form 4442 referrals, involving IMF campuses, when the IRM requiring the referral directs the referral be routed to the campus AM paper function within your directorate: All BMF, IRM-directed Form 4442 referrals, created by the Andover, Atlanta, Brookhaven, Memphis and Puerto Rico Directorates, are routed to the Cincinnati Campus. All BMF, IRM-directed Form 4442 referrals, created by the Austin, Fresno, Kansas City and Philadelphia Directorates, are routed to the Ogden Campus.
Other Referrals
21.3.5.4.4 (10-01-2003) Other Referrals Follow the procedures in this section to make referrals to Taxpayer Assistance Centers (TAC), media contacts, other IRS functions, and government agencies.
Directing Taxpayers to Taxpayer Assistance Centers (TAC)
21.3.5.4.4.1 (10-01-2020) Directing Taxpayers to Taxpayer Assistance Centers (TAC) Before directing taxpayers to a TAC, verify what type of services they are requesting. Advise taxpayers that you can usually provide the same level of service over the phone. For additional information on TAC criteria, see IRM 21.3.4.2, Standard Services in a Taxpayer Assistance Center (TAC). Make every attempt to resolve the issue and provide information on the alternative services available on IRS.gov, if appropriate. (To see a list of alternative options on IRS.gov, click on Help at the top of the page.) Note: When access to systems (e.g., IDRS, CFOL, SERP) is required to resolve the issue but is unavailable due to dead cycles and/or end of year updates, do not refer taxpayers to a TAC office for resolution. TAC offices are also experiencing the same system failures and are unable to provide any additional services for taxpayer resolution. If you cannot resolve the issue, the taxpayer insists on visiting a TAC office or it is determined that a face−to−face meeting is needed, verify the issue is in-scope for Field Assistance. If it is in-scope, advise the taxpayer that assistance is provided by appointment only. Note: The services provided at each TAC are listed on the Contact Your Local IRS Office page on IRS.gov. See IRM 21.1.1.3(8), Customer Service Representative (CSR) Duties, and IRM 21.3.4.2.4.5, Accounts Management Procedures for Appointment Service, for additional information.
Media Contacts
21.3.5.4.4.2 (05-03-2016) Media Contacts If a caller identifies themselves as a member of the media, refer to IRS Media Relations Office - Contact Number. Do not refer any other contact to Field Media Relations.
Referrals to Other IRS Functions/Government Agencies
21.3.5.4.4.3 (10-01-2018) Referrals to Other IRS Functions/Government Agencies See Tax Information for Government Entities, for: Tax information for Federal, State and Local Governments Tax information for Tribal Governments Information for the Tax-Exempt Bond Community Information for Governmental Liaisons See Appeals Account Resolution and Customer Service Contact, for referral of Appeals cases; open, unassigned or closed. Inquiries for cases not yet in Appeals should not be referred.
Receiving Referrals
21.3.5.4.5 (11-16-2023) Receiving Referrals The manager, referral coordinator, or designated employee must research the IRM reference noted in Part III, Section B, of the referral type and reason selected on the e-4442 application to determine if the referral is correct. All sites (including Taxpayer Assistance Centers (TAC)) must designate a referral coordinator. Manager, designated employee, or referral coordinator: Report and reject erroneous, incomplete, misrouted, illegible or late (transferred) referrals. Work together to eliminate erroneous referrals which prevent timely taxpayer response. Follow the table below to reject erroneous referrals to the originator. If And Then The referral is erroneous/ misrouted Less than 30 days old You may reject the referral to the originating office by EEFax, e-4442 application or hand carry if an open control is not present on the account. Upon receipt of the Form 4442, Inquiry Referral, if you have CII access, the case has an open control and new information is being provided, follow the guidance below before rejecting the 4442 back to the originator. Convert Form 4442 to a PDF and attach as a file to the open relevant control on CII. Enter a Case Note on CII to alert the employee. If CII access is not available, forward the 4442 to the correct person with the open control and leave a note on Accounts Management Services (AMS). The referral is erroneous/ misrouted Received when 30 or more days old Issue an interim letter before rejecting to the issuing office by EEFax, e-4442 application or hand carry if an open control is not present on the account. Upon receipt of the 4442, if you have CII access, the case has an open control and new information is provided, follow the guidance below before rejecting the 4442 back to the originator. Convert Form 4442 to a PDF and attach as a file to the open relevant control on CII. Enter a Case Note on CII to alert the employee. If CII access is not available, forward the 4442 to the correct person with the open control and leave a note on AMS. Review for TAS criteria. See IRM 13.1.7, Taxpayer Advocate Service (TAS) Case Criteria. Note: When rejecting a referral, explain the reason for the rejection.
Resolving Referrals
21.3.5.4.6 (10-01-2025) Resolving Referrals Work the oldest case first when resolving referrals. Select Next Case and the oldest referral you are profiled to work will automatically be assigned to you in A status. Review the e-4442 Case Notes tab and AMS narrative(s) for new notes or actions. Maintain referrals you are working in suspense until they are closed. Use the e-4442 Case Notes tab to leave notes each time you access the referral until the referral is resolved. Exception: If creating a CII case to resolve the referral, leave a closing resolution remark of on the e-4442 "Closing to CISxxxxxxx" and why CII case is needed (CISxxxxxxx=case ID). Address each issue and take the appropriate action (e.g., use the proper reference guides, IRM procedures, command codes). Update Accounts Management Services (AMS) or Integrated Data Retrieval System (IDRS) with any actions taken. You must use the Close button to populate the "Close - Response / Final Resolution" narrative box on the e-4442 to document actions taken prior to closing the referral. Note: The closing notes will systemically post to AMS. Make every attempt to resolve the case within the time frame given to the taxpayer.
Interim Referral Responses
21.3.5.4.6.1 (05-28-2025) Interim Referral Responses You must provide the taxpayer with an interim response (by telephone or in writing) if the response time given to the taxpayer is not met. See IRM 21.3.5.4, Referral Procedures, and IRM 21.3.3.4.2.2.1, Required Information for Interim Letters and Closing Letters. If a lapse of more than 30 days beyond normal processing time frames has occurred and the case does not meet Taxpayer Advocate Service (TAS) criteria, as outlined in IRM 21.1.3.18, Taxpayer Advocate Service (TAS) Guidelines, do not generate an additional Form 4442 referral or suggest calling back to check on the status of the account. Apologize for the additional delay and reassure the taxpayer we have notated the contact on their account and will notify them when the issue is resolved. Refer taxpayers to TAS when the contact meets TAS criteria, and you can't resolve the taxpayer's issue the same day. The definition of "same day" is within 24 hours. "Same day" cases include cases you can completely resolve in 24 hours, as well as cases in which you have taken steps within 24 hours to begin resolving the taxpayer's issue. Do not refer "same day" cases to TAS unless the taxpayer asks to be transferred to TAS and the case meets TAS criteria. Refer to IRM 13.1.7.5, Same Day Resolution by Operations. Referrals to TAS are made by completing an on-line Application for Tax Assistance Order (ATAO) (Form e-911) for electronic routing through AMS, or Form 911, Request for Taxpayer Advocate Service Assistance (And Application for Taxpayer Assistance Order), and routing the form to TAS if AMS is not available or you do not have AMS.
Interim Option e-4442
21.3.5.4.6.2 (05-28-2025) Interim Option e-4442 Select the follow-up button on Account Management Services (AMS) e-4442 when working a case that cannot be closed immediately. The interim option on AMS allows you to enter the follow-up date. The system moves the case to the top of your inventory, in bold, on the follow-up date. Examples of when to use this option are: Waiting for information/documents Waiting for payment or adjustment to post When sending interim letters, enter the date in the "Interim Response Sent" field on the Part II tab. Maintain referrals you are working in suspense until they are closed. Review the e-4442 Case Notes tab and AMS narrative(s) for new notes or actions every time you access the referral. Use the e-4442 Case Notes tab to leave notes each time you access the referral while in suspense. Note: e-4442 case notes do not post to AMS. They are used by the assigned employee to leave notes about the referral progression, and provide information if subsequent taxpayer contact is made.
Referral Aging Criteria
21.3.5.4.6.3 (05-28-2025) Referral Aging Criteria An account referral is considered aged if there is no response, action, or resolution by the 30th calendar day from the inquiry or last action date, unless the subject specific IRM includes a different timeframe.
Closures
21.3.5.4.6.4 (03-06-2019) Closures A referral is closed when the taxpayer's inquiry is resolved, and they are notified of the closing action. Notify the taxpayer by telephone or in writing. See IRM 21.3.3.4.2.2.1, Required Information for Interim Letters and Closing Letters. A generated notice based on a closing action on an account inquiry serves as notification if it clearly "responds to" or addresses the taxpayer's inquiry. After closure, a referral worked on the e-4442 application is viewable for 60 days. You have the ability to reopen a case that was worked during this time period.
