IRB-Brasil Resseguros S.A. (IRBR3) reported in a material fact on Tuesday, September 29, 2026, that Law No. 15,525/2026, originating from Bill No. 3,540/2026, was sanctioned, changing the tax rules applicable to local reinsurers. The changes take effect as of January 1, 2027, and January 1, 2030, depending on the tax.
Among the main points of Law 15,525 is the reduction of the Social Contribution on Net Income (CSLL) rate from 15% to 9%, starting January 1, 2027. The law also establishes that the 30% limits set out in Law No. 8,981/95 and Law No. 9,065/95 do not apply to the offsetting of tax loss carryforwards and negative CSLL bases of local reinsurers that have not been fully offset within three years from when they were recorded, including losses recognized before the publication of the new law.
In addition, Law 15,525 reduces the Corporate Income Tax (IRPJ) rate from 25% to 15%, starting January 1, 2030. According to IRB Brasil (IRBR3), the rate cuts may lead to a non-recurring accounting effect in its financial statements, arising from the remeasurement of deferred tax assets (DTAs) related to CSLL and IRPJ.
According to the company, this remeasurement may result in a partial write-down of deferred tax assets, with no impact on IRB Brasil’s cash position or solvency indicators.
