On 19 October 2026, the SII issued Exempt Resolution No. 141, establishing the official form and payment procedure for the unique substitute tax (impuesto único sustitutivo) applicable to balances of the reinvested earnings fund (fondo de utilidades reinvertidas), total taxable earnings balance, and excess withdrawals, as regulated by the eleventh and twelfth transitional articles of Law No. 21.850. This measure provides a mechanism for taxpayers to regularize historical retained earnings subject to prior tax deferral regimes. The resolution specifies the form layout, calculation methodology, due dates, and electronic payment channels. It targets corporate taxpayers who opted for the reinvestment regime under previous legislation and now face a mandatory substitution tax to close those cycles. The SII has enabled a dedicated module in its online portal for filing and payment.
Key Takeaways
- Mandatory Regularization: Companies with qualifying retained earnings balances must compute and pay the substitute tax using the newly prescribed form, effectively closing prior deferral benefits.
- Unified Form and Payment: A single form consolidates the declaration and payment for all three categories of balances, simplifying compliance for affected entities.
- Electronic Filing Only: Submission and payment must be completed electronically via the SII portal, with no paper alternative offered.
