CT | Corporation Tax Registration for Companies

Most limited companies in Ireland are legally required to register for Corporation Tax (CT) with the Office of the Revenue Commissioners (Revenue) within 4 weeks from the date of first income. If no income has yet been received, registration must occur within 12 months of incorporation. CT registration is essential, as it assigns your company a Tax Registration Number (TRN) — the foundation for all other tax registrations, including Employers Tax (PAYE), Relevant Contracts Tax (RCT), and Value Added Tax (VAT).

Entrust your CT registration to Chern & Co professionals — we handle all steps end-to-end via Revenue Online Service (ROS) as your authorised tax agent.

Important: Corporation Tax (CT) Registration Requirements for Proprietary Directors

As of October 2024, the Revenue of Ireland has tightened CT registration rules. All proprietary directors — i.e. directors or shareholders controlling more than 15% of the company’s share capital — must:

Hold an Irish PPS Number (PPSN)
Be registered for Income Tax

Revenue guidance (summary):

Shareholders holding over 15% are categorised as proprietary directors and must register for Income Tax and file Form 11 annually.
They are subject to self-assessment even if no other income exists — filing Form 11 remains mandatory.
Income from directorships is taxable in Ireland on an earnings basis, regardless of residence or where duties are performed.

PPSN vs IPN — Key Difference

PPSN (Personal Public Service Number) is the Revenue identifier and mandatory on the TR2 form for each director during CT registration.

IPN (Identified Person Number) is used only for CRO/RBO filings and cannot replace a PPSN in Revenue registrations.

Submissions omitting a valid PPSN or attempting to use an IPN instead are rejected — CT registration will not be completed. The two numbers are not interchangeable.

Note: If the company’s shareholder is another corporate entity (not an individual), and the appointed director does not own shares — i.e. is not a proprietary director — then PPSN and Income Tax registration are not required for that director.
