Santiago, February 17, 2026
The Director (S) of the SII, Carolina Saravia, explained that "the central objective of making this information transparent in time, aims to make the presentation of the Affidavits of Income, which are so relevant for the construction of the Income tax return proposals, a much more fluid process and with fewer observations for taxpayers, their accountants and tax advisors, and in this way, prevent themselves or their reports from facing greater inconveniences during the Income tax return."This is the first time that the Internal Revenue Service makes detailed information transparent regarding the most relevant validations that it applies during the stage of submitting the Affidavits of Income.

"A tax interpretation error today can compromise the viability of your business tomorrow. Our advice is not limited to 'filling out forms'; we sit at your table to validate that each strategic decision is protected. We shield your assets and that of your company from the active supervision of the SII, allowing you to focus on growth while we manage the complexity."
"Many see taxes as an inevitable expense. We see them as a business design variable. For an entry fee of 6 million, we not only resolve your legal questions; we audit your entire structure to ensure that there is not a single crack through which the [SII/Authority] can enter, and that you are not losing profitability due to poor planning. At the end of the day, the client does not pay us for the hours we work, but for the size of the problems we prevent from occurring."
We incorporate artificial intelligence tools into the internal work of the study, as support in the documentary review, cross-checking of background information and the preliminary analysis of tax scenarios and contingencies.
These tools organize and speed up the analysis, but they do not replace it: each report, writing and recommendation is reviewed and signed by a lawyer from the firm, and the background of each client is treated under the same confidentiality rules as the rest of the assignment.
Defense of high assets, ex-prisons, we avoid all risk scenarios prior to a study to prevent you from being imprisoned, we protect assets. And not only that, you will not be left with a criminal record, we will prevent your assets from being lost.
We create companies, modify them, buy corporate rights, companies.
Are you being investigated for tax fraud, or was it formalized? Contact us, we guarantee total confidentiality.
In the legal and corporate field, the true competitive advantage lies in real experience. My journey began in 1991 in the accounting area, where I led specialized offices, served as an accounting professor and assumed the head of a department in charge of more than 700 simultaneous accountings. This solid technical base allowed me to quickly evolve towards strategic tax advice.
Today, after more than 30 years of uninterrupted experience, I direct Lex Juicios Lawyers with a comprehensive vision: we understand the numbers from their accounting origin and we defend them with the maximum legal rigor. We design highly complex tax solutions to protect the assets of companies, SMEs, families and individuals, guaranteeing legal security and financial tranquility in each decision.
