COLOMBIA Trends and Developments Contributed by: Rodrigo Castillo Cottin, Ana María López and Alejandra Becerra, Rimon, P.C.
Two recent measures stand out: • Decree 175 (14 February 2025) reinstated a 1% stamp tax on the execution of public and private documents involving obligations above approxi - mately USD71,500. The tax applies to documents executed between 21 February and 31 December 2025, and covers instruments such as contracts, agreements, and deeds, provided they meet specific conditions regarding value and the nature of the parties involved. The measure reactivates a mechanism that had previously been suspended and is intended to generate short-term fiscal rev - enue through formal transactions. • Decree 572 (28 May 2025) amended existing income tax withholding and self-withholding rules. It introduced new rates applicable to vari - ous economic sectors and lowered the minimum thresholds that trigger the obligation to withhold. These adjustments apply from 1 June 2025, and modify the way advance payments of income tax are collected throughout the year. The decree also expanded the scope of transactions subject to withholding, aligning applicable rates with the characteristics of each activity. While both measures were issued under a declared State of Internal Commotion, they remain in force and continue to form part of the government’s fiscal response toolkit. Technological Advancements and the Role of the Colombian Tax Office In response to ongoing fiscal and administrative challenges, the Colombian Tax Office has prioritised strengthening oversight and improving compliance through technology-driven strategies. This institu - tional focus includes major investments in digital infrastructure, with a particular emphasis on AI and advanced data analytics as core tools to modernise tax administration. One of the most visible outcomes of this agenda is the electronic invoicing regime, which now operates on a real-time validation model. Before an invoice becomes legally effective, it must be reviewed and authorised electronically by the tax authority. This system has significantly improved the traceability of taxable trans -
actions and enabled concurrent – not retrospective – monitoring of business activity. Building on this foundation, the Colombian Tax Office is using predictive algorithms and machine-learning models to detect irregular patterns, flag potential non- compliance, and initiate targeted audits. These tools are supported by enhanced data integration, allowing cross-referencing with third-party information such as bank records, real estate registries, and customs dec - larations. In parallel, the authority has launched AI-based tools to assist taxpayers and is expanding the use of auto - mated audit procedures. While the fiscal effects of these innovations will materialise gradually, they signal a decisive shift towards a more proactive and data- centric tax enforcement model. Businesses, particu - larly those engaged in digital, cross-border, or high- volume activities, should remain attentive to evolving standards and prepare for increased scrutiny. Pension and Labour Reforms The pension reform, enacted as Law 2381 of 2024, is one of the few major policy initiatives approved dur - ing the current administration, following a complex legislative process. It introduces structural changes aimed at addressing long-standing coverage gaps and adapting the system to Colombia’s demographic trends. Scheduled to take effect on 1 July 2025, the law established a four-pillar model designed to pro - mote equity and long-term financial sustainability. Among its key features are a gradual reduction in required contribution weeks – from 1,300 to 1,000 by 2036 – and measures focused on improving access for women, including a 50-week credit per child (up to three). A transition regime preserves current rules for individuals nearing retirement. However, the reform’s enforceability has been brought into question: in May 2025, the Constitutional Court admitted a challenge alleging procedural flaws dur - ing congressional approval. While the law remains formally in force, the court temporarily suspended its administrative implementation, leaving room for legal uncertainty.
