The Finance (No. 2) Act 1998, designated as No. 15, introduces key additional taxation measures that complement the earlier Finance Act of the same year. This legislation encompasses a range of amendments to income tax, corporation tax, capital taxes, excise duties, and value-added tax (VAT). Notable provisions include enhancements to tax reliefs, updates to credits and thresholds, and targeted incentives designed for specific sectors.

Moreover, the Act ensures alignment of indirect tax provisions with European Union directives while bolstering the enforcement powers of Revenue. These technical modifications not only bolster compliance but also aim to support Ireland's overall economic competitiveness, thus forming an integral component of the annual tax legislative cycle that shapes the nation’s fiscal framework.
