UK Accounting & Filing Support for Irish Companies
If an Irish-incorporated company starts trading, employing staff, holding premises or carrying on other activity in the UK, additional UK accounting and filing obligations may arise.
ATA helps keep the UK side organised while ensuring the accounting information continues to reconcile back to the Irish company’s underlying records.
UK Obligations Can Arise in Different Ways
The filing position depends on what the Irish company is actually doing in the UK. These are common situations that should trigger a review.
UK Office or Branch
A physical UK place of business may create Companies House and tax obligations.
Trading in the UK
UK trading through people, premises or business arrangements may need to be reviewed for Corporation Tax purposes.
UK Employees
PAYE, payroll and employer reporting obligations may arise where employees work in the UK.
UK VAT Activity
UK sales, imports, stock movements and other transactions can create UK VAT questions.
UK Property
Owning, letting, developing or disposing of UK property may create separate UK tax obligations.
Management in the UK
Where strategic management and control takes place can affect the company residence analysis.
Keeping the Irish and UK Filing Position Connected
The practical challenge is often not simply another tax return. It is making sure both jurisdictions are working from consistent accounting information.
Irish company accounts and corporate filings.
Irish Corporation Tax records and filing information.
Irish VAT records and returns where applicable.
Irish payroll information where employees remain in Ireland.
Relevant Contracts Tax where the company operates in construction.
UK establishment and Companies House filing requirements.
UK Corporation Tax registration and returns where applicable.
UK VAT registration, records and returns where required.
UK payroll and employer compliance for UK employees.
Accounting schedules supporting the UK activity or establishment.
Does the Irish Company Need to Register in the UK?
An overseas company may need to register with Companies House if it establishes a place of business in the UK.
Registration with Companies House and liability to UK tax are separate questions, so both need to be considered.

UK Tax Can Apply Even Without a Traditional Branch
The UK tax position may depend on the nature of the activity, where business decisions are made, whether there is a permanent establishment, and whether the company holds UK property.
Permanent Establishment
A branch, office or dependent-agent arrangement can create a UK Corporation Tax presence.
Company Residence
Central management and control can create company residence and treaty questions.
UK Property
Non-UK companies can fall within UK Corporation Tax on UK property income and related activity.
One Set of Records. Clear UK Schedules. Better Coordination.
UK accounting for Irish companies works best when the UK schedules reconcile directly to the underlying Irish company records. ATA helps organise the accounting information so both sides remain connected.
This can reduce duplication, inconsistent figures and unnecessary back-and-forth between advisers.
Separate UK income, costs, assets, liabilities and payroll data.
Ensure UK schedules continue to reconcile to the Irish company records.
Maintain visibility across HMRC, Companies House, CRO and Revenue.
Provide clean schedules and supporting records to the relevant UK or Irish adviser.
The Right Expertise in the Right Jurisdiction
Some cross-border company issues can require jurisdiction-specific tax or legal input. ATA can keep the accounting work coordinated while working alongside the appropriate independent adviser where needed.
Where an Irish filing requires an authorised Irish agent or specialist input, ATA can provide the reconciled accounting information and work alongside the appropriate independent adviser.
Start With a Review of What the Company Is Doing in the UK
