On 2 October 2026, Portaria n.º 448-A/2026/1 was published, revising and fixing the unit tax rates for the Tax on Petroleum and Energy Products (ISP). This monthly adjustment mechanism reflects fluctuations in international energy markets and ensures alignment with EU minimum taxation directives. The revised rates apply to gasoline, diesel, LPG, natural gas, and electricity, impacting fuel retailers, energy-intensive industries, and logistics operators. The measure is part of the government’s ongoing fiscal policy to balance revenue objectives with competitiveness and environmental goals.
Key Takeaways
- Immediate Application: The new unit rates take effect from the date of publication, requiring fuel distributors and tax warehouses to update billing and accounting systems without delay.
- Cost Pass-Through: Companies in transport and logistics sectors must reassess pricing models and contractual fuel surcharge clauses to reflect the updated tax burden accurately.
