Contact Information: To make changes to this IRM section email *CI-HQ-IRM.
-
Goal: To provide guidance and clarity of the authority directive within the IRS-CI.
-
The authority to enforce federal laws is derived from a variety of statutes. These statutes may assign the enforcement of a given law to a particular department such as the Treasury Department and its bureaus including the Internal Revenue Service (IRS), or enforcement may simply fall to a legal arm of the government, such as the Department of Justice (DOJ).
-
The various departments of the government then further delegate the authority to enforce the laws through Orders and Directives issued to agencies. The agencies then issue Delegation Orders (DO) to specific functions and sometimes even specific positions of employment within the agency itself.
-
IRM 9.1.2, Authority, lists the authorities which other IRM sections cite to delegate authority.
-
The Director, FC and Director, ARIS are responsible for developing, maintaining, and overseeing this IRM and ensuring compliance with current policies and procedures.

-
Whenever an agent becomes aware that the authenticity or origin of a document may be in question, they should attempt to obtain handwriting exemplars of the parties involved. An agent's authority to summons a taxpayer or other witness for the purpose of taking handwriting exemplars is provided by . This authority does not violate any Constitutional rights or policies enunciated by Congress. Compulsion of handwriting exemplars is neither a search nor seizure subject to Fourth Amendment protections nor testimonial evidence protected by the Fifth Amendment privilege against self-incrimination. A handwriting exemplar is an identifying physical characteristic.
-
The basic authority for conducting searches and making seizures is found in the Fourth Amendment to the Constitution of the United States which states: The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. The Fourth Amendment protects individuals against unreasonable searches and seizures by the government. The scope of this protection extends to any area in which an individual has a reasonable expectation of privacy. Further, the Fourth Amendment provides that all warrants shall be based upon probable cause and supported by oath or affirmation.
-
provides that it shall be unlawful to have or to possess any property used, or intended for use, in violating the provisions of the internal revenue laws, or regulations prescribed under such laws, and that no property rights shall exist in any such property.
-
authorizes special agents to search warrants and seize personal property subject to forfeiture.
-
A search warrant may be issued pursuant to , and the Federal Rules of Criminal Procedure (Fed. R. Crim. P.), for the search of the personal property used, or intended for use, in violation of the internal revenue laws or regulations.
-
; ; ; ; ; and provide the statutory authority for searches and seizures conducted by CI special agents. Pertinent parts of Rule 41 provide for warrants to be issued by a federal judge or magistrate upon the affidavit of a law enforcement officer. A warrant issued under this rule may provide for the search and seizure of any of the following:
-
Evidence of the commission of a criminal offense.
-
Contraband, the fruits of crime, or things otherwise criminally possessed.
-
Property designed or intended for use, or which is or has been used in committing a criminal offense.
-
Person for whose arrest there is probable cause, or who is lawfully restrained.
-
-
The phrase, federal law enforcement officer, as used in Rule 41, refers to any government agent, other than an attorney for the government as defined in Fed. R. Crim. P. Rule 1(b)(1), who is engaged in the enforcement of the criminal laws and is within any category of officers authorized by the Attorney General to request the issuance of a search warrant.
-
For more information concerning search authority and procedure see IRM 9.4.9, Search Warrants, Evidence, and Chain of Custody.
-
Searches can be made without a warrant so long as the consent of the property owner is obtained first, or the search is incident to a lawful arrest.
-
A search without a warrant may be made with the consent of the person who has the right to give such consent. The consent must be voluntarily given and not the result of any undue influence or duress. Any coercion will invalidate the search and seizure. The courts have held that only persons whose constitutional rights have been violated will be heard in objection to the search. The rights guaranteed are personal and may be waived only by the person having the right of immediate possession. One person may not waive such rights for another unless the person, so waiving has authorized possession of the premises.
-
A person lawfully arrested may be searched without a warrant and the premises under their immediate custody and control may be searched for weapons.
-
For more information concerning search authority and procedure, see IRM 9.4.9, Search Warrants, Evidence and Chain of Custody.
-
The authority of special agents to make arrests is provided by . This section provides, in part, that a CI special agent is authorized: to execute and serve arrest warrants and to make arrests without warrant for any offense against the United States relating to the internal revenue laws that is committed in their presence or for any felony cognizable under such laws if they have reasonable grounds to believe that the person to be arrested has committed, or is committing, any such felony.
-
The Supreme Court has stated that, in the absence of a controlling federal statute, the law of arrest of the state where the arrest is made is controlling. In the absence of a statute authorizing a federal officer to make an arrest without a warrant, that officer has the same powers of arrest as a private citizen. The power of a special agent to make an arrest without a warrant as a private citizen, when valid under state law, is not made invalid because the crime is outside the scope of the internal revenue laws. An arrest without a warrant is a serious matter and could subject the person making the arrest to criminal and civil liability for false imprisonment or false arrest. Therefore, for a special agent to be authorized to make a warrantless arrest (as a private citizen), it is generally necessary that a violation constituting a felony be committed in their presence or they must reasonably believe that the person whom they arrest has committed a felony.
-
Every state has its own requirements in granting federal law enforcement officers state peace officer status. Even if peace officer status is recognized by your state, check with counsel before taking any position as a recognized peace officer.
-
There is no specific statutory authority for CI special agents to carry firearms. The General Counsel, Department of the Treasury, has concluded that no specific authority is necessary because where a federal officer has authority to make an arrest, they have implied authority to carry firearms. Authority for special agents to make arrests is contained in .
-
The authority to carry firearms is limited to the conduct of official duties in enforcing any of the criminal provisions of the internal revenue laws or other criminal provisions of laws relating to the IRS where the enforcement is the responsibility of the Secretary or their delegate.
-
Authority to carry or use privately owned weapons during off-duty hours, as a private citizen, is subject to local civil and criminal restrictions. Special agents may not use their position or credentials to qualify under state or local laws to purchase, license, carry, or use private weapons. Credentials may be displayed as occupational identification, upon request, but not to influence any decision a state or local law enforcement officer may make concerning the special agents ability to carry a concealed weapon.
-
authorizes the Secretary of the Treasury to compromise any civil or criminal tax case prior to referral to DOJ. This authority was delegated to the Commissioner under Treasury Order 150-10 and . Strict compliance with the statutory provisions is required to affect a compromise. Accordingly, an attempted settlement by subordinate IRS officials will not bar criminal prosecution. A valid compromise is as complete a discharge from prosecution as an acquittal by a jury.
-
CI pursues offers in compromise in investigations in which criminal proceedings are pending only if specifically requested by Counsel.
-
After referral of an investigation to the DOJ, authority to compromise rests with the DOJ.
-
Tender of tax or the actual payment thereof, prior to a verdict or plea of guilty, is not a bar to criminal prosecution.
-
When a taxpayer, represented by counsel, expresses a desire to negotiate an expedited plea agreement prior to the formal completion of an administrative investigation, the special agent will advise taxpayer¡¯s counsel:
-
The IRS does not have the authority to engage in plea negotiations, because this authority rests exclusively with the DOJ.
-
Plea negotiations must be conducted by either the United States Attorney¡¯s Office or the DOJ, Tax Division.
-
-
The authority to seize assets for forfeiture comes from the Internal Revenue Code (Title 26 of the USC) and Title 18 and 31 of the USC. For more information concerning seizure authority and procedure, see IRM Chapter 9.7, Asset Seizure and Forfeiture.
-

It further provides that no property rights shall exist in any such property, and that a search warrant may be issued as provided in and , for the seizure of such property. authorizes the Secretary to seize any property subject to forfeiture pursuant to , , and .
-
A search warrant may be issued for the seizure of property used or intended to be used in violation of the internal revenue laws. See . A seizure in violation of the Fourth Amendment will not sustain a forfeiture, unless the property seized is contraband per se.
-
Servicewide DO 9-1, located in IRM 1.2.2.10.1, Delegation Order 9-1 (formerly DO 157, Rev. 7), Seizure and Forfeiture of Personal Property, authorizes special agents to seize personal property for forfeiture to the United States when such property was used or intended to be used in violation of internal revenue laws other than Chapters 51, 52 and 53 of the Internal Revenue Code.
-

-
(within the investigatory jurisdiction of IRS),
-
(within the investigatory jurisdiction of IRS),
-
(within the investigatory jurisdiction of IRS).
-
-
The Secretary of the Treasury, through Treasury Orders 101-05 and Treasury Order 105-17, delegated the authority to the Under Secretary of Terrorism & Financial Intelligence. Treasury Directive 15-42 further delegated this authority to the Commissioner, IRS. The Commissioner issued Servicewide DO 9-2, located in IRM 1.2.2.10.2, Order Number 9-2 (Formerly DO-158, Rev. 2), Initiate Investigations and Seize and Forfeit Property under the Money Laundering Control Act and Bank Secrecy Acts, specifying various activities in the civil seizure and forfeiture process delegated to certain CI personnel.
Treasury Directive 15-42 provides delegation authority to the IRS for seizure and forfeiture authority over violations of and relating to violations of:-
and ; and
-
and that are within the investigatory jurisdiction of IRS pursuant to paragraph 3a.
-
-
The criminal forfeiture procedures found in Title 18, as they relate to the IRS, are governed by four statutory authorities. Three of these authorities are incorporated into the money laundering criminal forfeiture statute by reference, while the fourth is a consequence of the fact that criminal processes are governed by the Federal Rules of Criminal Procedure. These statutory authorities are as follows:
-
which states that the provisions of shall govern the seizure and disposition of any property subject to forfeiture under .
-
provides for a temporary restraining order prior to the conclusion of a criminal investigation to preserve the availability of the property for forfeiture by restraining transfer of the property or further encumbrances.
-
provides for the use of a seizure warrant for property subject to forfeiture under 18 USC 982 and 21 USC 853.
-
Pursuant to , and by incorporation of , customs laws relating to the seizure, summary and judicial forfeiture of property contained in et seq (Civil Administrative Forfeiture Procedures).
-
In addition, because criminal forfeiture is an integral part of the underlying criminal prosecution, the Federal Rules of Criminal Procedure govern the general process by which property is criminally forfeited.
-
-
Treasury Order 150-35 delegates criminal referral authority to the Commissioner and to Treasury General Counsel.
-
The Commissioner has the authority to refer all criminal matters within the jurisdiction of the IRS to the DOJ for grand jury investigation, criminal prosecution, or other criminal enforcement action requiring court order or DOJ approval.
-
Treasury General Counsel has exclusive authority to make referrals in criminal matters for judicial enforcement of summonses and to determine which court decisions of a criminal tax matter should be appealed.
-
Treasury General Counsel has concurrent authority with the Commissioner to refer a criminal matter to DOJ for pre-referral advice. This authority has been re-delegated to Chief Counsel by General Counsel Order No. 4, Delegation of Authority to Chief Counsel, located in IRM 30.2.2, General Counsel Orders and Directives (see Exhibit 30.2.2-6, General Counsel Order No. 4, Delegation of Authority to Chief Counsel).
