The Finance (No. 2) Act 1992 represents a significant update to Ireland's fiscal framework, designed to enhance revenue generation while supporting low- and middle-income households. Key amendments to income tax rate bands, personal allowances, and credits aim for a balanced approach, alongside clarifications on reliefs and residency rules. Notably, the provisions concerning PRSI ensure better alignment of the tax and social insurance systems, thereby modernising their administrative effectiveness.

Additionally, the Act addresses corporate tax through revisions to capital allowances and transfer pricing principles, enhancing Ireland's competitive landscape while mitigating risks of profit shifting. Reforms to capital taxes, VAT provisions, and excise duties further align with EU directives and health policy goals, promoting equity and compliance. With expanded investigative powers for the Revenue Commissioners, the Act ultimately strengthens the framework for compliance and enforcement, reflecting a commitment to fiscal consolidation and economic stability.
