Question 1

Do I still pay UK tax if I move from the UK to Ireland?

Accepted Answer

Usually yes, but only on UK-source items. Once you are non-resident under the Statutory Residence Test, often from your departure date with split-year treatment, your worldwide income generally falls out of the UK tax net. UK rental income, UK property gains, pay for UK workdays and some pensions stay UK-taxable, and Ireland taxes you as a resident under its own rules. Horizon files the departure-year return and tells you exactly what the UK keeps.

Question 2

Does the Common Travel Area mean I can ignore UK tax residence?

Accepted Answer

No. The Common Travel Area governs free movement between the UK and Ireland and has no bearing on tax residence. Your UK position is decided by the Statutory Residence Test, with days counted at midnight. Someone with four UK ties can become UK resident again on as few as 16 days, which regular short trips back from Dublin can breach. Horizon runs the test for the year you leave and the year after, and tells you how many UK days your ties allow.

Question 3

Will my UK pension be taxed in the UK or in Ireland?

Accepted Answer

It depends on the pension and the UK-Ireland treaty, in force since 1976. Most ordinary occupational and private pensions become taxable only in Ireland, your country of residence, and can often be paid gross once the position is in place. UK government-service pensions (civil service, NHS, armed forces, teachers) generally stay UK-taxable, and the position can differ if you are an Irish or dual national. Horizon makes the claim so the pension can be paid without UK deduction; the State Pension position is confirmed separately, and the Irish treatment with a local adviser.

Question 4

I am moving to the UK from Ireland. What should I sort out first?

Accepted Answer

Your start date, whether the year splits, and whether gains from an earlier absence can be re-taxed. If you were not UK resident in the previous three tax years, fewer than 46 UK days keeps you non-resident; if you were, it drops to 16. Priority rules pick among five arrival split-year cases. Four-year FIG relief may be open after at least 10 consecutive non-resident years. If you left the UK after at least four UK-resident years out of seven and return within five, the temporary non-residence rule can tax gains and certain income realised while away. Horizon identifies the case the priority rules give you, fixes the split date and says what the UK re-taxes.

Question 5

How much does a UK tax return cost if I live in Ireland, and can it all be done remotely?

Accepted Answer

£550 fixed for a non-resident or expat tax return, including the SA109 residence pages that HMRC's free online service cannot file. Personal tax returns start from £350 and complex returns from £750. Advisory work, such as planning a departure or a return, is quoted as a fixed fee agreed in writing before any work starts. There is never an hourly rate. Everything is handled remotely from London, with year-round support and direct access to the adviser, so nothing needs a trip from Ireland. Start with the free 30-minute clarity call.
