Ireland vs UK Salary: Which Gives You More Take-Home Pay?

Ireland and the UK share a similar PAYE tax system, the same language, and many of the same employers (especially in tech). But the take-home pay on the same gross salary is surprisingly different. Here's exactly how they compare.

Side-by-side comparison

The UK wins at every income level, with the biggest advantage in the €55,000-€100,000 range where Ireland's 40% band and USC bite hardest.

Why the UK takes less

Ireland's 40% rate starts too early. Ireland's higher rate (40%) kicks in at €44,000 for a single person. In the UK, the equivalent 40% rate doesn't start until £50,270 (~€59,000). That's a €15,000 band where Irish workers pay 40% and UK workers pay only 20%.

USC adds up. Ireland's Universal Social Charge (0.5-8%) is an additional layer that doesn't exist in the UK. At €60,000, USC costs about €2,400/year. The UK equivalent — National Insurance — is actually lower at 8% above £12,570.

PRSI vs NI: Ireland's PRSI (4.2%) and the UK's NI (8%/2%) are the social insurance components. The UK's rate is higher, but the threshold structure means the effective burden is similar.

But gross salaries tell a different story

Ireland often pays higher gross salaries than the UK, especially in tech. Dublin tech salaries frequently exceed London equivalents:

At senior levels, Dublin and London are comparable. But London's lower tax rates mean more take-home on the same gross.

Cost of living: Dublin vs London

Housing is the great equalizer. Dublin is expensive — not London expensive, but close:

• Dublin 1-bed: €1,600-2,200/month
• London Zone 2 1-bed: £1,500-2,000 (€1,750-2,350)
• Cork/Galway 1-bed: €1,100-1,500 (significantly cheaper than Dublin)

If you're choosing between Dublin and London, the net salary advantage of the UK is partially eaten by similar housing costs. But Cork or Galway vs a UK city outside London? Ireland could win on quality of life.

The UK's 60% tax trap vs Ireland's straightforward system

One area where Ireland is simpler: it doesn't have the UK's bizarre "60% tax trap" between £100,000-£125,140 where the personal allowance is withdrawn, creating an effective 60% marginal rate. Ireland's system is more predictable at high incomes.
