The country enters a new annual income tax filing season in a context marked by significant changes to the Tax Code. Recent amendments addressing tax avoidance and evasion not only update the legal framework, but also redefine the relationship between taxpayers, advisors, and the tax authority. This year, more than ever, tax compliance ceases to be a merely declaratory exercise and becomes a space where economic substance, documentary consistency, and financial traceability play an unavoidable role.
The reforms aim to close gaps that historically allowed avoidance practices that were difficult to challenge. The General Anti-Avoidance Rule (GAAR) has been strengthened, granting the Chilean Internal Revenue Service (SII) clearer interpretative authority to identify structures that, although formally compliant, lack genuine economic purpose. The distinction between abuse and simulation has become more precise, reducing the ambiguity that for years hindered the effective enforcement of these concepts. A clear message also emerges: advisors and facilitators who design or promote avoidance schemes will face more severe consequences.
At the same time, the fight against tax evasion is being modernized. The tax authority has invested in technological tools that enable more sophisticated data cross-checking, supported by predictive models and large-scale data analytics. Audit powers have been expanded, particularly in cross-border operations, corporate reorganizations, and related-party transactions. Penalties have also been strengthened, sending an unequivocal signal about the importance of transparency and accuracy in reported information.
All of this shapes an SII that approaches the tax filing season with a more refined strategy. Complex transactions will be subject to more thorough review; consistency between declared information and financial reality will be examined more closely; and risk models will allow the authority to focus its efforts on taxpayers and sectors with higher probabilities of non-compliance. The authority now operates not only with more tools, but with a more comprehensive view of taxpayer behavior.
In this context, tax advisory services take on a decisive role. Companies can no longer limit themselves to fulfilling formal requirements: they must demonstrate substance, justify decisions, and anticipate potential inquiries. Supporting documentation becomes a strategic pillar, especially in intragroup transactions, reorganizations, and the determination of taxable bases. Prevention, rather than reaction, becomes the key to navigating a more demanding regulatory environment.
