Every figure above is a separate call to the same engine the calculator uses, run at build time on 2026-08-12. The green column is the best available outcome at that income.
The Ireland options, priced
- Standard rates. Ordinary Irish income tax, USC and PRSI.
Ireland has one regime to model here, which makes the structure and the residency date the only levers that matter.
What actually moves the number
- Ireland is usually more expensive than the UK on this income, and the calculator says so rather than talking around it.
- USC applies on top of income tax and is the part people forget when they compare headline rates.
- Ireland has a remittance basis for non-domiciled residents, which the engine does not model, so treat the standard figure as the ceiling.
When Ireland starts taxing you
183 days in a tax year, or 280 days across two consecutive years with at least 30 in each. The Common Travel Area covers immigration, not tax.
The other half is the UK side. Leaving the UK tax net is the Statutory Residence Test, and running a UK company from outside the UK raises Central Management and Control and Permanent Establishment questions that are separate from your own residence. Running a UK limited company while living abroad covers both.
What this calculation assumes
- Social security is the weak point in this calculation. The model charges the destination country's employee contributions and drops UK National Insurance the moment residence moves. In practice UK NI often continues for a period after you leave, and which country you contribute to is set by a social security agreement rather than by where you are tax resident. Treat the take-home figure as the optimistic end of the range, and the gap is largest where the destination charges no social security of its own.
- Employer National Insurance is shown as an employer cost, so it is outside your take-home. It does not disappear when you move, and it is often the reason an employer says no.
- Cross-border scenario detected. Check the applicable double-tax treaty between United Kingdom and Ireland.
- Budget 2025: single standard band EUR 44,000. Relief via tax credits not allowance; USC+PRSI stack on top.
The last items are the engine's own disclosures, reproduced rather than summarised. Where a regime is not modelled it is named as not modelled, because a caveat you have to go looking for is not a caveat.
