Why the gap exists
Dublin's executive market grew meaningfully after Brexit, as financial services firms (Bank of America, Citigroup, JPMorgan, Morgan Stanley) established or expanded EU operations there to preserve passporting rights. The city now hosts a dense cluster of major technology companies and a maturing financial services and payments ecosystem. Ireland's tax structure is surprisingly similar to the UK's at senior executive comp levels: 40% income tax above €44K, plus USC (Universal Social Charge) of 8% above €70K, plus PRSI of 4.1% - giving an effective rate around 46% at $300K, slightly higher than London.
Despite the similar headline rates, Dublin offers several structural advantages: EU market access post-Brexit, a lower cost of living than central London, a smaller but fast-growing executive network, and stronger tax treatment for stock options under KEEP and other Irish regimes. Compensation in Dublin for equivalent roles typically trails London by 15–25% in gross terms, which can erode the quality-of-life advantages. Housing in Dublin has become severely constrained since 2020, with rental and purchase costs near parity with London for city-center locations. For executives with EU citizenship or Irish heritage, Dublin is often the easier relocation logistically.
