The Companies Act 2014, which came into effect on June 1, 2015, consolidates and simplifies company law in Ireland, making it easier for businesses to understand and comply with their legal obligations. It introduces new company types and reforms, establishes directors' fiduciary duties, mandates companies to appoint secretaries with necessary skills, and offers provisions for audit exemptions. Key changes include a new summary approval procedure for restricted activities, clear capital structure guidelines, and streamlined processes for company mergers and winding-up.
