UK tax help in Ireland
Two tax systems, one land border, and Buzz on both sides of it — our Northern Ireland office lives with UK/Irish cross-border tax every day.
Ireland is the one country on this list where Buzz is genuinely local: Buzz Accounting operates in Northern Ireland, and UK/Irish cross-border questions — workers, landlords, companies, pensions — are daily work rather than an exotic specialism.
The usual cases
- Moved to Dublin, kept a UK property — Irish residents are taxed on worldwide income (with a remittance basis for non-domiciled foreign income in some cases); the UK taxes the rent first, Ireland credits it. NRL returns from us, Irish return by your Irish accountant — or ask us; we work with both systems.
- Cross-border workers — living in one jurisdiction, employed in the other: payroll, residence and relief claims that most accountants on either side see rarely and we see weekly.
- Companies — a UK Ltd trading into Ireland, or directors living in the Republic running a UK company: corporate residence and PAYE positions need managing on both sides (how we handle it).
- Pensions and NI — UK State Pension uprating applies in Ireland (no freeze), which makes voluntary NI unambiguous good value for most movers.
Three Ireland stories we see every month
Names changed, numbers real. If one of these is you, the fix is usually days of work, not months.
The Newry–Dundalk commute
Director living in the Republic, company in Newry. Payroll ran UK PAYE only; Irish residence made him Irish-taxable too. Fixed with the cross-border relief workings both sides — the NI office does this weekly.
The Dublin move that kept the Belfast house
Rented out on moving south: NRL scheme applies (it's a UK property, he's non-UK-resident now), Irish return credits the UK tax. Both returns handled inside the Buzz group.
Two pensions, no freeze
Ireland uprates the UK State Pension normally, so voluntary NI is unambiguous: six Class 2 back-years bought, £342/yr each, index-linked, alongside the Irish PRSI record.

Asked from Ireland, constantly
I work in Belfast but live in Dublin — where do I pay tax?+
Both systems touch you: UK PAYE on the employment, Irish residence taxes worldwide income with transborder relief typically eliminating the double charge. It has to be set up, not assumed.
Can Buzz handle both my UK and Irish filings?+
The UK side fully; the Irish side through the group's NI operation and its Republic-facing work — one thread either way, no relay race between strangers.
Does the CTA change anything?+
The Common Travel Area covers residence and work rights, not tax. The UK-Ireland treaty does the tax work.
