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
- The company is assumed to distribute everything it can in the same year, after a director salary at the UK National Insurance threshold. Leaving profit in the company, or paying into a pension from it, changes the answer and is usually worth modelling.
- Corporation tax is charged at UK rates throughout, because a company incorporated in the UK stays UK tax resident wherever its director lives.
- Cross-border scenario detected. Check the applicable double-tax treaty between United Kingdom and Ireland.
- Source-country (United Kingdom) dividend withholding tax of 0% applied on the gross dividend; a foreign tax credit is granted in Ireland up to the residence-country liability (relief under the applicable double-tax treaty).
- 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.
