Contact usIFRS 18 replaces NIC 1
IFRS 18, Presentation and Disclosure of Information in Financial Statements, applies to annual periods starting on January 1, 2027, with comparative information from the previous year.
Major taxpayers, forced to adopt IFRS
Resolution MH-DGT-RES-0015-2026 states that large taxpayers must keep their accounts in accordance with IFRS; other taxpayers may choose to use IFRS for SMEs or IFRS for large companies.
The fiscal criterion prevails
Accounting treatment under IFRS does not determine the tax obligation: tax reconciliation is reinforced as an obligatory mechanism to align accounting profit with the taxable base.
