On 29 September 2026, Brazil published Law No. 15,525/2026, introducing targeted corporate income tax changes for local reinsurance companies. Specifically, the Social Contribution on Net Profit (CSLL) rate applicable to local reinsurers will decrease from 15% to 9% for taxable events occurring on or after 1 January 2027. From 1 January 2027, the 30% taxable-income offset limitation will not apply to tax losses or negative CSLL bases that remain unutilized three years after they were generated, including qualifying balances generated before the new law was published. Additionally, the 10% corporate income tax surtax will no longer apply to local reinsurers beginning 1 January 2030.
- Colombia adopts earthquake-related tax relief and investment incentives
In Opinion 1737 (issued 21 September 2026), the Colombian Tax Authorities clarified that tax relief measures and investment incentives established by Legislative Decrees 1413 and 1419, would apply to all Colombian taxpayers, not only to those affected by the earthquake. The relief measures include reductions in penalties and default interest, relief for omitted filings and amended returns. Most relief elections and applications must be made by 19 November 2026. Qualifying new investments that support reconstruction, recovery and economic activity in municipalities within the emergency territory may benefit from a 20% corporate income tax rate that can be reduced to as low as 15% based on job creation, accelerated depreciation at an annual rate of 50% and a value-added tax exemption for qualifying imports. The principal investment incentives apply during the 2026 and 2027 tax years, with certain benefits available through 31 December 2027.

The new tranche of Administrative Guidance addresses the treatment of explicitly conditional taxes and the use of local financial accounting standards under a qualified domestic minimum top-up tax.
