A DIAN audit visit is a means of evidence in the tax procedure: the tax inspection is decreed by an order that is notified and states the facts to be proven and the officials commissioned, and a record is drawn up (Tax Code, Art. 779); the accounting inspection also ends in a record, a copy of which is delivered once it is closed and signed (Art. 782). A criminal search and seizure, by contrast, is an investigative step in the criminal process governed by Law 906 of 2004: the prosecutor leading the investigation may order it, to obtain material evidence and physical evidence, and the judicial police carries it out (Art. 219). It is allowed only with reasonably grounded reasons to conclude that the investigated crime was probably committed by the owner or holder of the property, or that the instruments or proceeds of the crime are inside (Art. 220), backed at least by a judicial police report, a sworn statement or material evidence (Art. 221). The order must specify the places to be searched, and indiscriminate orders or orders that designate the property globally are not allowed (Art. 222); it must be carried out within 30 days during the inquiry or 15 days after the charges are formulated, with a single extension (Art. 224).
During the search the judicial police must stay within the authorized places, ensure the least possible restriction of rights and draw up a record listing the places searched, the objects seized and the persons arrested; the record is read to those affected, who may ask that their disagreements be noted, and if they refuse to sign the officer notes this under oath (Art. 225). If the procedure takes place between 6:00 p.m. and 6:00 a.m. the Procuraduría General de la Nación (the public-oversight body) must accompany it, but it is not suspended if they are absent (Art. 225, par.). Owners or holders are entitled to a copy of the record (Art. 227). The judicial police then reports to the prosecutor and sends the inventory (Art. 228), and the search is subject to a subsequent legality control before the guarantees judge (juez de control de garantías) within the legal time limits; the company must act immediately, with a tax and DIAN focus. If the order lacks essential requirements, the search is invalid and the evidence that depends on it is excluded (Art. 232). Written communications between the suspect and their lawyers, and files with confidential information from that relationship, cannot be searched (Art. 223). Even if the prosecutor acts over a possible tax crime, the offenses of Articles 434A and 434B of the Penal Code require the amount to be “defined by official assessment”; a search at that stage is therefore often a sign that other offenses are being investigated, and a lawyer should read the order.
