Irish company tax registrations and Revenue records under review

Incorporating a company with the CRO does not complete its tax setup. A trading company must identify the Revenue registrations, filing dates and records that match its activity, staff, cross-border supplies and payment flows.

StartCompany.ie provides tax services from €400, including registration and access to support for Corporation Tax, VAT, employer PAYE and related compliance. The scope should be agreed around the company’s facts rather than assuming every tax head is required.

Corporation Tax and starting to trade

Revenue requires a company to register for tax when it starts a business, and Irish companies generally file an annual CT1 through ROS. The widely cited 12.5 percent rate applies to qualifying trading income; other income and special regimes can have different treatment.

A company should document when trading begins, its business activity, contracts and management. Incorporation date and tax commencement are related but not identical concepts.

VAT, PAYE and other registrations

VAT depends on taxable activities, turnover, thresholds, cross-border acquisitions and voluntary-registration conditions. Revenue may request evidence that the business is genuinely carrying on or intends to carry on taxable activity.

A company paying employees or directors may need employer PAYE registration and real-time payroll reporting. Construction and subcontracting can also bring RCT, while imports and EU trade can create customs, VIES or Intrastat work.

  • Corporation Tax registration and CT1 planning.
  • VAT registration, VAT3 and annual RTD requirements.
  • Employer PAYE and payroll reporting.
  • RCT or cross-border reporting where relevant.
  • ROS access, payment dates and record keeping.

Tax support for non-resident founders

Foreign ownership does not remove Irish company obligations. Director residence, where management decisions occur, permanent establishments, payroll and home-country reporting can create questions in more than one jurisdiction.

A registered office or Irish incorporation alone does not settle tax residence or treaty entitlement. Cross-border companies should obtain advice covering both Ireland and the founders’ home jurisdictions.

Working with StartCompany.ie

StartCompany.ie’s tax services begin from €400, with the final scope depending on registrations and ongoing work required. Prepare the incorporation documents, activity description, expected turnover, customers, suppliers, staff, director pay and cross-border plans.

Ask for a written list of included registrations and returns. Bookkeeping, payroll, annual accounts, tax returns and advisory projects are distinct tasks even when delivered by the same professional team.

Revenue states that a company must register and operate PAYE on directors’ remuneration, even without other employees.

Is all Irish company income taxed at 12.5 percent?

No. The 12.5 percent rate applies to qualifying trading income; other income and regimes can use different rates.

Does a registered office establish tax residence?

No. Address, central management, treaty and substance questions require a separate tax analysis.
