Why Ireland for Your Business?

Ireland is known for its pro-business environment, EU market access, and competitive corporation tax regime. While the standard 12.5% corporation tax rate applies to most Irish trading companies, larger multinational groups may be subject to the OECD’s 15% minimum effective tax rate under Pillar Two rules. Selecting the right company type depends on your business model, risk appetite, and long-term plans.
