Gross salary 🇮🇪 Ireland net/mo 🇺🇸 United States net/mo
50,000 / 55,000 €3,329/mo (20.1%) $3,860/mo (15.8%)
70,000 / 75,000 €4,194/mo (28.1%) $5,109/mo (18.3%)

Gross salary appears in each country's own currency at matching nominal values rather than converted, which is what you want when weighing up two offers quoted locally. The effective rate is in brackets.

The American column is federal-only, so the real gap may be narrower

As with every American comparison on this site, the figures above leave out state income tax, which spans 0% in Texas, Florida and seven other states to more than 13% in California. Dublin's technology and pharmaceutical cluster competes for people who could realistically move to American hubs in high-tax states such as California or Massachusetts, in which case the true gap closes considerably against what is shown here. Move instead to a no-tax state like Texas and the American advantage lands close to what the table implies.

Irish USC climbs more steeply than most people anticipate

The Universal Social Charge is the principal reason the Irish effective rate rises from 20.1% at 50,000 euros to 38.1% at 120,000, a sharper curve than the headline 20% and 40% income tax bands would on their own produce. Our complete USC breakdown lists the exact thresholds. It is a distinctly Irish mechanism with no direct American parallel, sitting on top of ordinary income tax and PRSI.

Questions readers ask

Judged on federal tax alone the US holds a clear lead at every level, for example $6,281/month against 4,992 euros/month at the 90k euro versus $95k pairing. State income tax is excluded, and depending on which state is genuinely on the table it could either close that gap substantially or leave it broadly intact.

A corporate tax rate of 12.5%, among the lowest in the OECD, an English-speaking workforce inside the EU, and decades of deliberate foreign direct investment policy have made Dublin the European or EMEA base of choice for many large American technology and pharmaceutical firms, which in turn creates heavy local demand for technical and professional staff.

The Universal Social Charge is a surcharge layered on top of Irish income tax, climbing from 0.5% to 8% across four income bands. It is the main reason the Irish effective rate accelerates as sharply as it does through the professional range. Our dedicated USC guide sets out the exact figures.

It does not. Irish public healthcare, with a means-tested private alternative, is paid for through general taxation and PRSI. American healthcare is usually employer-sponsored and carries real premiums and deductibles that appear in neither take-home figure.
