The short answer: Ireland pays more on paper, the UK is closer than you think after tax
Irish tech salaries are consistently higher than their UK equivalents in gross terms, typically by 10–20% for the same role. A Senior Software Engineer earns a median of €108,000 in Ireland versus £95,000in the UK. At the exchange rate in mid–2026 (roughly €1 = £0.86), that is a gross advantage of around €15,000 in Ireland's favour.
The comparison looks quite different once you factor in tax. Ireland's marginal rate for higher earners combines Income Tax, USC, and PRSI into something approaching 52%. The UK tops out at 42% above £50,270. That gap erodes a significant chunk of Ireland's gross premium. At the Senior Engineer salary example above, an Irish engineer takes home roughly €67,000–€69,000; their UK counterpart on £95,000 takes home around £62,000–£63,500, which converts to approximately €72,000 at current rates. The UK can actually come out slightly ahead on net.

Why does Ireland pay more in gross terms?
Three structural factors drive Ireland's gross salary premium, and they are unlikely to change any time soon.
- 1
Every major US tech company has a presence in Dublin. Google, Meta, Apple, Microsoft, Amazon, LinkedIn, and Salesforce: virtually the entire Fortune 50 tech sector has engineering operations in Ireland. These companies benchmark compensation globally, not locally. When a Dublin office is competing for engineers against offices in San Francisco and New York, Irish salaries get pulled up toward US levels. That effect is most pronounced at senior and staff levels, and it lifts the whole market.
- 2
Ireland is a small country with a lot of tech demand. Ireland has a population of about 5 million. The supply of Senior and Staff engineers is inherently limited, while demand from global companies is not. That imbalance is most visible at the top of the market, where Ireland's median salary for Principal Engineers and Engineering Managers can exceed equivalent London figures even after currency conversion.
- 3
Dublin costs almost as much as London to live in. Employers know this and factor it into offers. The gross premium is partly a cost-of-living offset. The question is whether it is a sufficient offset, which is where people's views diverge.
The tax reality: where the UK catches up
Ireland has a genuinely high marginal tax rate. Once your gross income exceeds €36,800, you are paying 40% Income Tax, 8% USC, and 4% PRSI on each additional euro, giving an effective marginal rate of around 52%. The UK's equivalent above £50,270 is 42% (40% Income Tax, 2% National Insurance). That is a 10 percentage point gap, and it matters more as salaries rise.
Estimates assume standard tax credits with no additional deductions. Individual results vary. Exchange rate: €1 = £0.86 (mid-2026).
Salary is only part of the picture
If you are deciding between an Ireland and UK tech role, the gross salary and the tax number are the starting point, not the conclusion. Here is what else matters.
- Housing costs: Dublin rents are among the highest in Europe. London is similarly brutal. Neither city offers an easy path to affordability, but Dublin has a more constrained rental supply at the lower end of the market. This is a real quality-of-life factor that the gross salary premium does not fully compensate for.
- Equity and total compensation: The US multinationals based in Ireland almost all operate global RSU and options programmes. A Senior Engineer or Engineering Manager at one of these companies will often receive €20,000–€50,000+ in annual equity on top of base salary. That changes the calculus dramatically. If you are comparing a base salary at an Irish hyperscaler against a UK startup, you are not comparing the same thing.
- Career trajectory: London has a deeper ecosystem for early-stage startup work and a wider range of industries. Dublin's market is heavily concentrated around a small number of very large employers, which provides stability and excellent compensation but fewer paths to founding-team equity or broad industry exposure. This is a real trade-off, not a knock on either market.
- Quality of life: Ireland performs well on healthcare access, social infrastructure, and working hours. London wins on cultural density, international travel connections, and sheer variety. This comes down to what you actually want from where you live.
One important nuance for non-EEA engineers considering Ireland: the RSUs and equity that define the Silicon Docks financial package do not count toward the Critical Skills Employment Permit salary threshold. DETE evaluates gross base salary only, and if your base is below €40,904, the equity component does not rescue the application. For contractors rather than permanent hires, our Ireland contract rate calculator models take-home across all three company structures.
So, should you work in Ireland or the UK?
If you are a senior engineer or engineering manager targeting one of the hyperscalers with a Dublin presence, Ireland is the better financial choice on a gross basis, and when you factor in equity, often on a total-comp basis too. The gross premium is real and meaningful at this level, and it holds even with the tax haircut for top-of-market roles earning €120K+.
If you are a mid-level engineer without a clear specialisation, the financial case for Ireland is much weaker. After tax, the gap nearly disappears. At that point the decision should be driven by the specific company, the role, your career goals, and frankly, where you want to live. Do not make it primarily about the salary number.
For either market, the highest-paying discipline right now is AI and data engineering. If that is your background, both Ireland and the UK will pay you well, though Ireland's concentration of hyperscaler AI investment makes it the stronger market for those specific roles in 2026.

Frequently asked questions
Does Ireland or the UK pay more for tech jobs in 2026?
Ireland pays more in gross terms, typically by 10–20% for the same role. A Senior Software Engineer earns a median of €108,000 in Ireland versus £95,000 in the UK. However, after tax the gap narrows significantly. Ireland's marginal rate reaches 52% above €36,800 (Income Tax, USC, and PRSI combined), while the UK's equivalent above £50,270 is 42%. At Senior Engineer level, Irish take-home is roughly €67,000–€69,000 versus £62,000–£63,500 for the UK, which at current exchange rates converts to approximately €72,000, putting the UK slightly ahead net.
What is the take-home pay difference between Ireland and the UK after tax?
At Senior Software Engineer level (€108,000 Ireland vs £95,000 UK), Irish take-home is approximately €67,000–€69,000 while UK take-home is approximately £62,000–£63,500. At mid-2026 exchange rates (€1 = £0.86), that UK figure converts to roughly €72,000, making the UK slightly ahead after tax despite the lower gross. The gap reverses at the very top of the market (€120,000+) where Ireland's gross premium is large enough to win even after the tax haircut. Use the Ireland and UK take-home calculators to model your exact figures.
How do Ireland and UK income tax rates compare for tech workers?
Ireland's marginal rate above €36,800 is approximately 52% (40% Income Tax, 8% USC, 4% PRSI). The UK's marginal rate above £50,270 is 42% (40% Income Tax, 2% National Insurance). That 10 percentage point gap on marginal rates is the main mechanism eroding Ireland's gross salary advantage. Both countries have lower rates on the first tranche of income: Ireland taxes income up to €36,800 at roughly 28%, while the UK taxes income from £12,571–£50,270 at 20%.
Is it worth moving from the UK to Ireland for a higher tech salary?
It depends on your level and target employer. For senior engineers and engineering managers targeting hyperscalers in Dublin (Google, Meta, Apple, Microsoft), the financial case is strong: the gross premium is real, often supplemented by RSU packages worth €20,000–€50,000+ annually. For mid-level engineers without a clear specialisation, the after-tax difference largely disappears. Non-financial factors, including Dublin's housing costs, career trajectory, and lifestyle preferences, often matter more than the salary comparison at that level.
Which tech roles show the biggest Ireland vs UK salary gap?
Engineering managers and staff-plus engineers show the largest Ireland premium, driven by hyperscaler compensation benchmarking against US market rates. AI and data engineers also earn a meaningful premium in Ireland due to concentrated hyperscaler AI investment in Dublin. Cloud and platform engineers show a moderate premium. For most roles, Ireland's gross advantage is largest at senior and staff levels (where it can exceed €15,000–€20,000) and smallest at mid level, where after-tax parity is common.
Does RSU equity count toward Ireland vs UK salary comparisons?
Equity is a significant factor for Irish hyperscaler roles and can change the comparison dramatically. Senior engineers and engineering managers at Dublin-based US multinationals often receive €20,000–€50,000+ in annual RSU vesting on top of base salary. Note that RSUs and equity do not count toward Ireland's Critical Skills Employment Permit salary threshold: the Department of Enterprise evaluates gross base salary only, so equity does not rescue a base salary that falls below the permit threshold.
