The Finance Act 1997 (No. 22) implements the Budget for that year, encompassing significant amendments to Ireland's tax framework, which includes income tax, corporation tax, VAT, excise duties, and capital taxes. The Act revises tax bands and credits, enhances existing reliefs, and refines anti-avoidance measures. Additionally, it fortifies the powers of Revenue to ensure compliance while introducing tailored incentives aimed at stimulating economic activity and employment opportunities.

Moreover, the Act incorporates technical amendments that enhance tax administration processes, including assessments, appeals, and provisions related to interest and penalties. As a cornerstone of Ireland's annual fiscal cycle, this legislation is instrumental in shaping tax policy and revenue strategies in response to evolving economic conditions and governmental priorities.
