The development
SII Circular No. 53 of 2025 explains the reduction to 12.5% for financial years 2025, 2026 and 2027, under Law No. 21,755. This is an earlier rule with significant effects during 2026.
The benefit applies to the Pro Pyme General regime under Article 14 D No. 3. Businesses under the tax transparency regime in No. 8 are exempt from First Category Income Tax.
Why it matters
Before projecting the tax burden, the regime should be confirmed and the financial year distinguished from the tax year, also reviewing the corresponding provisional monthly payments (PPM).
