The donations window lasts one year from 1 December 2026; the foreign-assets declaration window lasts twelve months from 1 January 2027. Exact closing dates require the applicable legal computation and official instructions. Article 26; Article 8(4); first, third and ninth transitional articles.

The investor’s perspective
Look beyond the corporate tax rate
A useful investment model connects the tax paid by the company with the return received by its shareholders. It also considers tax certainty, the timing of distributions and the cost of compliance.
The articles below explain the reform through that cross-border perspective. They distinguish the company’s cash flow from the investor’s total tax cost, and identify the information needed before acting.

Legal sources and further measures
Law No. 21,850, published on 17 October 2026 is the statutory source. The SII Reconstruction Law portal provides thematic guidance. The effective-dates guide links each measure to its legal basis.
SII Exempt Resolution No. 141, dated 19 October 2026, establishes online IUSIF filing and payment through Form 50: STUT codes 855/856, FUR codes 857/858 and excess-withdrawal codes 859/860. The associated corporate tax credit cannot be deducted against the 10% tax. The taxable-base circular has not been identified in the official index as at 21 October 2026. Deployment of the new fields for every taxpayer has not been verified.
For Treasury arrangements, the 180-day window gives 15 April 2027 under IDC’s legal calculation, counting complete calendar days from the day after publication, under the second transitional article and Civil Code Articles 48–50. No Treasury instruction expressly stating that date has been verified. See the Treasury announcement of 19 October 2026 and check the applicable instructions and individual debt assessment.
