How does Irish income tax compare to UK income tax at tech salaries?
At most tech salary ranges, Ireland has a slightly higher combined effective rate than the UK when you include USC and PRSI versus National Insurance. At €90,000 (roughly £76,000 at a 1.18 rate), an Irish employee pays approximately 40% effective rate across income tax, USC, and PRSI. A UK employee at the same gross in GBP pays roughly 33–36% across income tax and National Insurance. However, a direct comparison requires converting to the same currency and accounting for the fact that Dublin and London gross salaries for equivalent roles are often at different absolute levels.
